Bio-Engineered Graphene-Based Cage for Efficient Local Enrichment and Biodegradation of Aqueous Organic Wastes

Abstract: Abstract Microorganism immobilization has attracted great attention as a traditional method to overcome aqueous organic wastes containing N, N-dimethylformamide (DMF). In this approach, graphene oxide was modified with functional polymer firstly to obtain micro-composites material (PGO), and then the prepared composites were deposited on the surface of copper mesh (CM) to block the meshes and CM@PGO was achieved. Moreover, cage-shaped model was designed based on CM@PGO and P. denitrificans was packed inside the cage for batch experiments. This strategy could enrich the local concentration of DMF due to the formation of hydrogen bonds with the oxygen-containing groups from PGO and the character of bacteria in captivity could also contribute to the process of degradation. Results showed that the approach could remove DMF more efficiently about 15% compared with free microorganism and presented excellent cycling performance. Meantime, physical adsorption and chemical adsorption were both contributed to the process of PGO adsorption, and the adsorption isotherm fits Langmuir model well, furthermore, the theoretical maximum of adsorption ability calculated through Langmuir model is 95 mg/g. In other words, this cage-shaped CM@PGO provided a facile platform for treating various wastewaters by altering the species of packed microorganisms, which exhibited considerable prospects for wastewater treatment.

The effect of replacing saturated fat with mostly n-6 polyunsaturated fat on coronary heart disease: a meta-analysis of randomised controlled trials

Abstract: Abstract Background A cornerstone of conventional dietary advice is the recommendation to replace saturated fatty acids (SFA) with mostly n-6 polyunsaturated fatty acids (PUFA) to reduce the risk of coronary heart disease (CHD). Many clinical trials aimed to test this advice and have had their results pooled in several meta-analyses. However, earlier meta-analyses did not sufficiently account for major confounding variables that were present in some of those trials. Therefore, the aim of the study was to account for the major confounding variables in the diet heart trials, and emphasise the results from those trials that most accurately test the effect of replacing SFA with mostly n-6 PUFA. Design Clinical trials were identified from earlier meta-analyses. Relevant trials were categorised as ‘adequately controlled’ or ‘inadequately controlled’ depending on whether there were substantial dietary or non-dietary differences between the experimental and control groups that were not related to SFA or mostly n-6 PUFA intake, then were subject to different subgroup analyses. Results When pooling results from only the adequately controlled trials there was no effect for major CHD events (RR = 1.06, CI = 0.86–1.31), total CHD events (RR = 1.02, CI = 0.84–1.23), CHD mortality (RR = 1.13, CI = 0.91–1.40) and total mortality (RR = 1.07, CI = 0.90–1.26). Whereas, the pooled results from all trials, including the inadequately controlled trials, suggested that replacing SFA with mostly n-6 PUFA would significantly reduce the risk of total CHD events (RR = 0.80, CI = 0.65–0.98, P = 0.03), but not major CHD events (RR = 0.87, CI = 0.70–1.07), CHD mortality (RR = 0.90, CI = 0.70–1.17) and total mortality (RR = 1.00, CI = 0.90–1.10). Conclusion Available evidence from adequately controlled randomised controlled trials suggest replacing SFA with mostly n-6 PUFA is unlikely to reduce CHD events, CHD mortality or total mortality. The suggestion of benefits reported in earlier meta-analyses is due to the inclusion of inadequately controlled trials. These findings have implications for current dietary recommendations.

Defense related decadienal elicits membrane lipid remodeling in the diatom Phaeodactylum tricornutum.

Abstract: Diatoms rapidly release extracellular oxylipins (oxygenated lipids) including polyunsaturated aldehydes in response to herbivory and other stresses. Oxylipins have several defense-related activities including inhibition of reproduction in herbivores and signaling to distant diatoms. Physiological changes in diatoms exposed to varying levels of oxylipins are only beginning to be understood. In this study, Phaeodactylum tricornutum cultures were treated with sublethal concentrations of the polyunsaturated aldehyde trans,trans-2,4-decadienal (DD) to assess effects on lipid composition and membrane permeability. In cells treated with DD for 3 hr, all measured saturated and unsaturated fatty acids significantly decreased (0.46-0.69 fold of levels in solvent control cells) except for 18:2 (decreased but not significantly). The decrease was greater in the polyunsaturated fatty acid pool than the saturated and monounsaturated fatty acid pool. Analysis of lipid classes revealed increased abundances of phosphatidylethanolamine and phosphatidylcholine at 3 and 6 hr. Concomitantly, these and other membrane lipids exhibited increased saturated and monounsaturated acyl chains content relative to polyunsaturated acyl chains compared to control cells. Evidence of decreased plasma membrane permeability in DD treated cells was obtained, based on reduced uptake of two of three dyes relative to control cells. Additionally, cells pre-conditioned with a sublethal DD dose for 3 hr then treated with a lethal DD dose for 2 hr exhibited greater membrane integrity than solvent pre-conditioned control cells that were similarly treated. Taken together, the data are supportive of the hypothesis that membrane remodeling induced by sublethal DD is a key element in the development of cellular resistance in diatoms to varying and potentially toxic levels of polyunsaturated aldehydes in environments impacted by herbivory or other stresses.

Embodied science and mixed reality: How gesture and motion capture affect physics education

Abstract: Abstract A mixed design was created using text and game-like multimedia to instruct in the content of physics. The study assessed which variables predicted learning gains after a 1-h lesson on the electric field. The three manipulated variables were: (1) level of embodiment; (2) level of active generativity; and (3) presence of story narrative. Two types of tests were administered: (1) a traditional text-based physics test answered with a keyboard; and (2) a more embodied, transfer test using the Wacom large tablet where learners could use gestures (long swipes) to create vectors and answers. The 166 participants were randomly assigned to four conditions: (1) symbols and text; (2) low embodied; (3) high embodied/active; or (4) high embodied/active with narrative. The last two conditions were active because the on-screen content could be manipulated with gross body gestures gathered via the Kinect sensor. Results demonstrated that the three groups that included embodiment learned significantly more than the symbols and text group on the traditional keyboard post-test. When knowledge was assessed with the Wacom tablet format that facilitated gestures, the two active gesture-based groups scored significantly higher. In addition, engagement scores were significantly higher for the two active embodied groups. The Wacom results suggest test sensitivity issues; the more embodied test revealed greater gains in learning for the more embodied conditions. We recommend that as more embodied learning comes to the fore, more sensitive tests that incorporate gesture be used to accurately assess learning. The predicted differences in engagement and learning for the condition with the graphically rich story narrative were not supported. We hypothesize that a narrative effect for motivation and learning may be difficult to uncover in a lab experiment where participants are primarily motivated by course credit. Several design principles for mediated and embodied science education are proposed.

Measurement the Mentality of Residents  of the New Districts and Planned in Relation
with the  Guality of Life Components (Case Study: Jahed neighborhood of Mashhad)

Abstract: Paying attention only to the growth of cities and to avoid developing developmental approaches toward cities has led to the emergence of macrocosmic phenomena, which has a direct impact on the quality of life in cities. A remarkable point in dealing with quality of life is to consider it in all dimensions (subjective and objective), so that it can be comprehensively evaluated. Therefore, the present article aims to analyze and evaluate the quality of life (two objective and subjective dimensions) in urban planning areas seeking to improve the quality of life in these neighborhoods by increasing the environmental components.The study area is Jahed Shahr  in 12th district of Mashhad. The criteria and indicators for the objective and subjective quality of life in four levels have been developed hierarchically. The method used is objective and applied in terms of descriptive-analytical method.Data were collected using library and field studies. Using the Cochran formula, 372 individuals were selected as sample size and questionnaires distributed as simply randomized . Data analysis was done using SPSS and AMOS software. Results: The quality of life in Jahed Shahr  Neighborhood was assessed  moderate to weak level  (only in the good transportation sector) and the objective quality of life is moderately upward (only in the components of social security and leisure).

Vibration Noise Modeling for Measurement While Drilling System Based on FOGs

Abstract: Aiming to improve survey accuracy of Measurement While Drilling (MWD) based on Fiber Optic Gyroscopes (FOGs) in the long period, the external aiding sources are fused into the inertial navigation by the Kalman filter (KF) method. The KF method needs to model the inertial sensors’ noise as the system noise model. The system noise is modeled as white Gaussian noise conventionally. However, because of the vibration while drilling, the noise in gyros isn’t white Gaussian noise any more. Moreover, an incorrect noise model will degrade the accuracy of KF. This paper developed a new approach for noise modeling on the basis of dynamic Allan variance (DAVAR). In contrast to conventional white noise models, the new noise model contains both the white noise and the color noise. With this new noise model, the KF for the MWD was designed. Finally, two vibration experiments have been performed. Experimental results showed that the proposed vibration noise modeling approach significantly improved the estimated accuracies of the inertial sensor drifts. Compared the navigation results based on different noise model, with the DAVAR noise model, the position error and the toolface angle error are reduced more than 90%. The velocity error is reduced more than 65%. The azimuth error is reduced more than 50%.

Association of maternal and umbilical cord blood leptin concentrations and abnormal color Doppler indices of umbilical artery with fetal growth restriction

Abstract:
Background: Fetal growth restriction (FGR) is a condition with heterogeneous pathophysiology which characterized by fetal weight less than the tenth percentile for gestational age. Several factors have impact on maternal, placental and fetal due to growth restriction.
Objective: The aim of this study was to investigate the relationship between levels of leptin in the cord, and serum leptin of mothers also abnormal color Doppler indices of umbilical artery with fetal growth restriction.
Materials and Methods: This is a cross sectional study conducted in Isfahan, Iran, 2015-2016. We recruited 40 women with singleton pregnancies complicated by fetal growth restriction (Group I) and 40 pregnant women with normal fetal growth (Group II) with matched age. Maternal serum and umbilical artery leptin levels were determined with Enzyme-Linked immunosorben method. Also, color Doppler ultrasound of umbilical artery was performed.
Results: Mean maternal and fetal leptin levels were lower in the FGR group compared to the normal group (36.58±(20.99) and 7.42 ±(4.08)vs. 47.32±(22.50) and 30.49±(14.50) respectively). Also, mean fetal leptin level was lower in the group with abnormal color Doppler sonographic indices compared to the normal group (7. 40 ±(4.10)vs 27.06±(15.80), respectively).
Conclusion: This study indicated that maternal and fetal leptin levels are correlated with FGR originating from damaged placental function; also fetal leptin level can indicate changes in color Doppler sonographic indices.

A Dynamic and Adaptive Selection Radar Tracking Method Based on Information Entropy

Abstract: Nowadays, the battlefield environment has become much more complex and variable. This paper presents a quantitative method and lower bound for the amount of target information acquired from multiple radar observations to adaptively and dynamically organize the detection of battlefield resources based on the principle of information entropy. Furthermore, for minimizing the given information entropy’s lower bound for target measurement at every moment, a method to dynamically and adaptively select radars with a high amount of information for target tracking is proposed. The simulation results indicate that the proposed method has higher tracking accuracy than that of tracking without adaptive radar selection based on entropy.

EL CHOCHO  (Lupinus mutabilis Sweet) , COMPLEMENTO NUTRICIONAL EN GESTANTES ADOLESCENTES, AMARILIS - HUÁNUCO – 2009

Abstract: Experimentalmente  determinamos el valor nutricional del chocho (Lupinus mutabilis Sweet) como complemento nutricional en gestantes adolescentes tempranas desnutridas. Para ello se escogió a cuatro gestantes a partir del Cuarto mes de embarazo, distribuidas en grupo A y C (control) en igual número. El chocho fue administrado vía oral en forma de ensalada a razón de 100 gr diario por 90 días consecutivos al grupo A, mientras al grupo control se le brindó orientación y consejería sobre nutrición. Se calculó el peso antes de la gestación, durante el I, II y III trimestre, con la tabla de ganancia de peso para gestantes, normado por el Ministerio de Salud. Al realizar la evaluación al final de la investigación, se observó que las gestantes del grupo A, a las cuales se aplicó el estímulo  incrementaron su peso correspondiente al embarazo, y un ligero incremento que corresponde a la frecuencia del 4%, algo significativo, como  complemento sumatorio nutricional, en comparación con el grupo control, donde las gestantes, incrementaron sólo el peso correspondiente a la ganancia del embarazo, demostrando que el chocho es un complemento nutricional poco significativo en la dieta de la embarazada.

Comparative Outer Membrane Protein Analysis of High and Low-Invasive Strains of Cronobacter malonaticus

Abstract: Cronobacter are an important group of foodborne pathogens that has been linked to life-threatening infections in both infants and adults. The major infections associated with Cronobacter species are neonatal meningitis, necrotizing enterocolitis, and septicaemia. There are seven species in the Cronobacter genus, of which only three are of clinical importance; Cronobacter sakazakii, Cronobacter malonaticus, and Cronobacter turicensis. To date most studies have focussed on C. sakazakii as it is the major species associated with neonatal infections. However, recently C. malonaticus, in particular sequence type 7 (ST7), has been noted as being prevalent in adult infections and therefore warranting further investigation. In this study, eight strains of C. malonaticus ST7, that had been isolated from a wide range of sources and varied in their in vitro virulence, were chosen for proteomic analysis of their outer membrane proteins (OMPs). One-dimensional gel analysis revealed a ~29 kDa size band that was only present in the highly invasive strains. Subsequent mass spectrometric analysis identified several peptides that matched the flagellin protein. The presence of flagellin protein was confirmed in 2D gel spot. Mass spectrometry analysis of total OMPs revealed that the four highly invasive C. malonaticus strains expressed the main flagellum proteins that were absent from the four low invasive strains. These were the flagellar hook protein FlgE, flagellar hook-associated protein 1, flagellar hook-associated protein, flagellin, and flagellar hook-filament junction protein FlgL. This data indicates that C. malonaticus flagellar proteins may have an important role in the organism's invasion properties.

Classical Dialogue: Allusion and intertextuality in Charl-Pierre Naudé’s Against the Light

Abstract: The contemporary Afrikaans poet Charl-Pierre Naudé is one of the most promising voices in South African poetry today. Following two award-winning Afrikaans collections, Naudé s debut collection in English, Against the Light (2007), demonstrates learned intertexual references to classical literature, particularly the Roman poets Horace and Catullus. These Latin poets become competing models for Naudé’s own poetics, either passionate and personal, or political and pastoral. In post-apartheid South Africa, after a period of dramatic social change, ultimately Catullus offers himself as the more compelling poetic model for this South African writer.


A practical method of I-131 thyroid cancer therapy dose optimization using estimated effective renal clearance

Abstract: In thyroid cancer patients with renal impairment or other complicating factors, it is important to maximize I-131 therapy efficacy while minimizing bone marrow and lung damage. We developed a web-based calculator based on a modified Benua and Leeper method to calculate the maximum I-131 dose to reduce the risk of these toxicities, based on the effective renal clearance of I-123 as measured from two whole-body I-123 scans, performed at 0 and 24 h post-administration.

Современные предпосылки будущего арктических трудовых ресурсов

Abstract: В связи с уникальным геополитическим положением России в Арктическом регионе, возрастающей заинтересованностью государства в развитии арктических территорий и реализацией различных арктических проектов проблема сохранения населения Российской Арктики и обеспечения Арктической зоны трудовыми ресурсами приобретает все большую актуальность. Статистическая оценка демографических процессов свидетельствует о сокращении численности населения в арктических регионах России. При этом в период хозяйственного освоения и фактически до начала 1990-х гг. На Севере и Крайнем Севере России, в отличие от других арктических государств, всегда преобладало население, проживающее на постоянной основе. По экспертным оценкам, уже к 2018 г. Регионы Арктической зоны в целом начнут испытывать нехватку трудовых ресурсов. Исследование построено на основе данных, полученных в ходе изучения демографических процессов в Мурманской области. Область была выбрана как наиболее урбанизированный регион Российской Арктики с развитыми системами расселения, крупными городскими поселениями и относительно высокой плотностью населения. В то же время в Мурманской области, по сравнению с другими арктическими регионами, наблюдается наиболее интенсивный отток населения, особенно молодого возраста. Причиной значительной убыли молодежи являются миграционные процессы, которые связаны не только с групповой спецификой молодежи (ее мобильностью), но и с особенностями условий социализации и самореализации в регионе. Результаты социологических исследований условий и качества жизни населения Мурманской области, проведенных в период с 2008 по 2016 гг., позволили выявить «критические точки» в оценке населением, в том числе молодежью, различных аспектов жизни в регионе. В группе молодых жителей региона выявлены устойчивые миграционные настроения и планы.

Formaldehyde Fixation of Extracellular Matrix Protein Layers for Enhanced Primary Cell Growth

Abstract: Coating tissue culture vessels with the components of the extracellular matrix such as fibronectin and collagens provides a more natural environment for primary cells in vitro and stimulates their proliferation. However, the effects of such protein layers are usually rather modest, which might be explained by the loss immobilized proteins due to their weak non-covalent association with the tissue culture plastic. Here we describe a simple protocol for a controlled fixation of fibronectin, vitronectin and collagen IV layers by formaldehyde, which substantially enhances the stimulation of primary cell proliferation by these extracellular proteins.


Signal-to-noise ratio evaluation of magnetic resonance images in the presence of an ultrasonic motor

Abstract: Abstract Background Safe robot-assisted intervention using magnetic resonance imaging (MRI) guidance requires the precise control of assistive devices, and most currently available tools are rarely MRI-compatible. To obtain high precision, it is necessary to characterize and develop existing MRI-safe actuators for use in a high magnetic field (≥3 T). Although an ultrasonic motor (USM) is considered to be an MRI-safe actuator, and can be used in the vicinity of a high field scanner, its presence interferes with MR images. Although an MR image provides valuable information regarding the pathology of a patient’s body, noise, generally of a granular type, decreases the quality of the image and jeopardizes the true evaluation of any existing pathological issues. An eddy current induced in the conductor material of the motor structure can be a source of noise when the motor is close to the isocenter of the image. We aimed to assess the effects of a USM on the signal-to-noise ratio (SNR) of MR images in a 3-T scanner. The SNR was compared for four image sequences in transverse directions for three orientations of the motor (x, y, and z) when the motor was in the “off” state. The SNR was evaluated to assess three artifact reduction methods used to minimize the motor-induced artifacts. Results The SNR had a range of 5–10 dB for slices close to the motor in the x and y orientations, and increased to 15–20 dB for slices far from the motor. Averaging the SNR for slices in all cases gave an SNR loss of about 10 dB. The maximum SNR was measured in the z orientation. In this case, the SNR loss was almost the same as that of other motor orientations, approximately 10 dB, but with a higher range, approximately 20–40 dB. Conclusions The selection of certain scanning parameters is necessary for reducing motor-generated artifacts. These parameters include slice selection and bandwidth. In developing any MRI-compatible assisted device actuated by a USM, this study recommends the use of an approximately 3-mm slice thickness with minimum bandwidth to achieve optimized SNR values when a USM is operating close to (within approximately 40 mm) the region being imaged. The SNR can be further enhanced by increasing the number of signal averages, but this is achieved only at the cost of increased scan duration.

Under Pressure: Interactions between Commensal Microbiota and the Teleost Immune System

Abstract: Commensal microorganisms inhabit every mucosal surface of teleost fish. At these surfaces, microorganisms directly and indirectly shape the teleost immune system. This review provides a comprehensive overview of how the microbiota and microbiota-derived products influence both the mucosal and systemic immune system of fish. The cross talk between the microbiota and the teleost immune system shifts significantly under stress or disease scenarios rendering commensals into opportunists or pathogens. Lessons learnt from germ-free fish models as well as from oral administration of live probiotics to fish highlight the vast impact that microbiota have on immune development, antibody production, mucosal homeostasis, and resistance to stress. Future studies should dissect the specific mechanisms by which different members of the fish microbiota and the metabolites they produce interact with pathogens, with other commensals, and with the teleost immune system.


Design of Fatigue Life Test System of the Energy Efficient Heavy Transmission

Abstract: During the development process of heavy transmission,a cyclic loading fatigue life test is required to carry out in a certain load to verify the reliability of the internal gear,shaft,bearing,box,and the overall system.

Antennal olfactory responses of adult meadow spittlebug, Philaenus spumarius, to volatile organic compounds (VOCs).

Abstract: The meadow spittlebug, Philaenus spumarius L. (Hemiptera, Aphrophoridae) is a commonly found vector of Xylella fastidiosa Wells et al. (1987) strain subspecies pauca associated with the "Olive Quick Decline Syndrome" in Italy. To contribute to the knowledge of the adult P. spumarius chemoreceptivity, electroantennographic (EAG) responses of both sexes to 50 volatile organic compounds (VOCs) including aliphatic aldehydes, alcohols, esters, and ketones, terpenoids, and aromatics were recorded. Measurable EAG responses were elicited by all compounds tested. In both sexes, octanal, 2-octanol, 2-decanone, (E)-2-hexenyl acetate, and vanillin elicited the strongest antennal amplitude within the chemical groups of aliphatic saturated aldehydes, aliphatic alcohols, aliphatic acetates and aromatics, respectively. Male and female EAG responses to sulcatol, (±)linalool, and sulcatone were higher than those to other terpenoinds. In both sexes, the weakest antennal stimulants were phenethyl alcohol and 2-pentanone. Sexual differences in the EAG amplitude were found only for four of test compounds suggesting a general similarity between males and females in antennal sensitivity. The olfactory system of both sexes proved to be sensitive to changes in stimulus concentration, carbon chain length, and compound structure. Compounds with short carbon chain length (C5-C6) elicited lower EAG amplitudes than compounds with higher carbon chain length (C9-C10) in all classes of aliphatic hydrocarbons with different functional groups. The elucidation of the sensitivity profile of P. spumarius to a variety of VOCs provides a basis for future identification of behaviorally-active compounds useful for developing semiochemical-based control strategies of this pest.

An ML-Based Radial Velocity Estimation Algorithm for Moving Targets in Spaceborne High-Resolution and Wide-Swath SAR Systems

Abstract: Multichannel synthetic aperture radar (SAR) is a significant breakthrough to the inherent limitation between high-resolution and wide-swath (HRWS) compared with conventional SAR. Moving target indication (MTI) is an important application of spaceborne HRWS SAR systems. In contrast to previous studies of SAR MTI, the HRWS SAR mainly faces the problem of under-sampled data of each channel, causing single-channel imaging and processing to be infeasible. In this study, the estimation of velocity is equivalent to the estimation of the cone angle according to their relationship. The maximum likelihood (ML) based algorithm is proposed to estimate the radial velocity in the existence of Doppler ambiguities. After that, the signal reconstruction and compensation for the phase offset caused by radial velocity are processed for a moving target. Finally, the traditional imaging algorithm is applied to obtain a focused moving target image. Experiments are conducted to evaluate the accuracy and effectiveness of the estimator under different signal-to-noise ratios (SNR). Furthermore, the performance is analyzed with respect to the motion ship that experiences interference due to different distributions of sea clutter. The results verify that the proposed algorithm is accurate and efficient with low computational complexity. This paper aims at providing a solution to the velocity estimation problem in the future HRWS SAR systems with multiple receive channels.

High Dose MicroCT Does Not Contribute Toward Improved MicroPET/CT Image Quantitative Accuracy and Can Limit Longitudinal Scanning of Small Animals

Abstract: Obtaining accurate quantitative measurements in preclinical Positron Emission Tomography/Computed Tomography (PET/CT) imaging is of paramount importance in biomedical research and helps supporting efficient translation of preclinical results to the clinic. The purpose of this study was two-fold: (1) to investigate the effects of different CT acquisition protocols on PET/CT image quality and data quantification; and (2) to evaluate the absorbed dose associated with varying CT parameters.Methods: An air/water quality control CT phantom, tissue equivalent material phantom, an in-house 3D printed phantom and an image quality PET/CT phantom were imaged using a Mediso nanoPET/CT scanner. Collected data was analyzed using PMOD software, VivoQuant software and National Electric Manufactures Association (NEMA) software implemented by Mediso. Measured Hounsfield Unit (HU) in collected CT images were compared to the known HU values and image noise was quantified. PET recovery coefficients (RC), uniformity and quantitative bias were also measured.Results: Only less than 2 and 1% of CT acquisition protocols yielded water HU values < −80 and air HU values < −840, respectively. Four out of 11 CT protocols resulted in more than 100 mGy absorbed dose. Different CT protocols did not impact PET uniformity and RC, and resulted in <4% overall bias relative to expected radioactive concentration.Conclusion: Preclinical CT protocols with increased exposure times can result in high absorbed doses to the small animals. These should be avoided, as they do not contributed toward improved microPET/CT image quantitative accuracy and could limit longitudinal scanning of small animals.

Ile lingwistyki w slawistyce, ile slawistyki w lingwistyce?

Abstract:
How Much Linguistics in Slavistics, How Much Slavistics in Linguistics?
The author makes an attempt to discuss the current role of linguistics among other disciplines of Slavonic studies (Slavistics), i.e. literature and cultural studies. The second part of the question in the title refers to the place of Slavonic linguistic studies within contemporary Polish linguistics. On the basis of preliminary observations and queries one may propose several hypotheses: 1) Slavonic linguistics in Poland differs significantly from the research on Polish language, both with regard to methodology and topics; 1.a) Inside Slavonic linguistics there is another division, between Russian and non-Russian Slavistics; 2) Slavonic and Polish Linguistics are also divided in the frames of Polish universities and Academy of Sciences; c) The main scientific forums, such as journals and conferences, reflect the divisions mentioned above, what results in relatively isolated communities in various fields of Slavonic linguistics, i.e. research on Polish, Russian and other Slavonic languages. To justify and illustrate the hypotheses in question, the author analyses the organizational structures of selected scientific centres, the contents of the most distinguished linguistic journals in Poland, as well as themes of conferences and the International Congress of Slavists.

Aboliendo las fronteras entre la historia natural y la magia natural. El Sylva sylvarum y la Historia vitae et mortis de Francis Bacon

Abstract: En este artículo investigo las historias naturales de Francis Bacon haciendo énfasis en la latina Historia vitae et mortis y el póstumo Sylva Sylvarum. Mi tesis es que el filósofo inglés no estaba interesado en compilar historias naturales de particulares, sino de las virtudes, de los procesos y de la actividad oculta de la materia. Los dos escritos mencionados representan la ejemplificación de este interés. A pesar de sus muy diferentes estructuras y composiciones, comparten muchas características que los eleva al nivel de la filosofía natural. Como se muestra en este artículo, su relación con la teoría de la materia, la práctica experimental involucrada, y su carácter operativo representan elementos específicos de la metafísica y la magia natural.

Extreme anoxia tolerance in crucian carp and goldfish through neofunctionalization of duplicated genes creating a new ethanol-producing pyruvate decarboxylase pathway

Abstract: Abstract Without oxygen, most vertebrates die within minutes as they cannot meet cellular energy demands with anaerobic metabolism. However, fish of the genus Carassius (crucian carp and goldfish) have evolved a specialized metabolic system that allows them to survive prolonged periods without oxygen by producing ethanol as their metabolic end-product. Here we show that this has been made possible by the evolution of a pyruvate decarboxylase, analogous to that in brewer’s yeast and the first described in vertebrates, in addition to a specialized alcohol dehydrogenase. Whole-genome duplication events have provided additional gene copies of the pyruvate dehydrogenase multienzyme complex that have evolved into a pyruvate decarboxylase, while other copies retained the essential function of the parent enzymes. We reveal the key molecular substitution in duplicated pyruvate dehydrogenase genes that underpins one of the most extreme hypoxic survival strategies among vertebrates and that is highly deleterious in humans.

Perceived Intensity and Discrimination Ability for Lingual Electrotactile Stimulation Depends on Location and Orientation of Electrodes

Abstract: Malfunctioning sensory systems can severely impact quality of life and repair is not always possible. One solution, called sensory substitution, is to use another sensory system to bring lost information to the brain. This approach often involves the use of bioengineered devices that electrically stimulate somatosensory fibers. Interestingly, the tongue is an ideal location for electrotactile stimulation due to its dense innervation, moisture, and protected environment. Success with transmitting visual and vestibular information through the tongue indicates promise for future applications. However, sensitivity and discrimination ability varies between individuals and across the tongue surface complicating efforts to produce reliable and consistent sensations. The goals of the present study were to investigate these differences more precisely to better understand the mechanosensory innervation of the tongue so that future electrotactile devices can be designed more effectively. Specifically, we tested whether stimulation of certain regions of the tongue consistently result in better perception, whether the spacing of stimulating electrodes affects perceived intensity, and whether the orientation of electrodes affects perceived intensity and discrimination. To test these hypotheses, we built a custom tongue stimulation device, recruited 25 participants, and collected perceived intensity and discrimination data. We then subjected the data to thorough statistical analyses. Consistent with previous studies, we found that stimulation of the anterior medial tongue region was perceived as more intense than stimulation of lateral and posterior regions. This region also had the best discrimination ability for electrodes. Dividing the stimulated tongue area into 16 distinct regions allowed us to compare perception ability between anterior and posterior regions, medial and lateral regions, and the left and right sides of the tongue. Stimulation of the most anterior and medial tongue resulted in the highest perceived intensity and the best discrimination ability. Most individuals were able to perceive and discriminate electrotactile stimulation better on one side of the tongue, and orientation of stimulating electrodes affected perception. In conclusion, the present studies reveal new information about the somatosensory innervation of the tongue and will assist the design of future electrotactile tongue stimulation devices that will help provide sensory information to people with damaged sensory systems.

Ethnomedicinal uses, phytochemistry and pharmacological aspects of the genus Premna: a review

Abstract: Context: The genus Premna (Lamiaceae), distributed throughout tropical and subtropical Asia, Africa, Australia and the Pacific Islands, is used in folk medicine primarily to treat inflammation, immune-related diseases, stomach disorders, wound healing, and skin diseases. Objectives: This review exhaustively gathers available information on ethnopharmacological uses, phytochemistry, and bioactivity studies on more than 20 species of Premna and critically analyzes the reports to provide the perspectives and directions for future research for the plants as potential source of drug leads and pharmaceutical agents. Methods: A literature search was performed on Premna species based on books of herbal medicine, major scientific databases including Chemical Abstract, Pubmed, SciFinder, Springerlink, Science Direct, Scopus, the Web of Science, Google Scholar, and ethnobotanical databases. Results: More than 250 compounds have been isolated and identified from Premna species, comprising of diterpenoids, iridoid glycosides, and flavonoids as the most common secondary metabolites, followed by sesquiterpenes, lignans, phenylethanoids, megastigmanes, glyceroglycolipids, and ceramides. Many in vitro and in vivo studies have been conducted to evaluate the biological and pharmacological properties of the extracts, and isolated compounds of Premna species with antimicrobial, antioxidant, anti-inflammatory, immunomodulatory, antihyperglycaemia, and cytotoxic activities. Conclusion: The bioactive compounds responsible for the bioactivities of most plants have not been well identified as the reported in vivo pharmacological studies were mostly carried out on the crude extracts. The isolated bioactive components should also be further subjected to more preclinical studies and elaborate toxicity study before clinical trials can be pursued.


Is health-related quality of life the same for elderly polish migrants, Turkish migrants and German natives? Testing the reliability and construct validity of the Sf-36 health survey in a cross-cultural comparison

Abstract: Objective: The Sf-36 is the most widely used instrument to measure health-related quality of life (HRQoL) with the most convincing evidence of both internal consistency and test–retest reliability. In addition, it is appropriate for use among elderly and minority groups like migrants. The aim of this study is to investigate and compare the reliability and the factorial structure of the Sf-36 in a sample of elderly migrants and natives. The hypothesis is that the construct (the HRQoL consisting of eight dimensions correlated with two components) is the same for elderly Turkish migrants, Polish migrants and German natives. This means that the Sf-36 model shows good psychometric properties and model invariance for the three groups investigated in this study. Methods: The Sf-36 v.2 was forward and backward translated to Turkish and Polish. In this cross-sectional study, interviews were conducted with a sample of elderly migrants from Turkey (n = 100), from Poland (n = 103) and a sample of elderly German natives (n = 101). All data were entered and analysed using SPSS version 21 and AMOS Graphics. Cronbach’s α was used to analyse the reliability of the Sf-36. Multi-group confirmatory factor analysis (MGCFA) and structural equation modelling (SEM) were used for the Sf-36 model invariance testing. Results: The reliability of the Sf-36 was good to excellent for all Sf-36 dimensions (α > 0.7) except for General Health (0.55) in the Polish group. Multi-group confirmatory factor analysis (MGCFA) showed non-invariance between the three groups (CMIN: 180.172, df: 51, CMIN/df: 3.533, p < 0.001, CFI: 0.895, RMSEA: 0.092 for the unconstrained model). Model modifications resulted in a good model fit for the Polish group. However, an applicable common Sf-36 model for the three groups was not attained. Conclusion: This study doesn’t support the idea that the factorial structure of the Sf-36 with two components and eight dimensions is the same across three ethnically and culturally diverse groups of elderly subjects. Therefore, comparing subscale scores of the Sf-36 between different ethnic groups may be problematic.

Effect of Systematic Control of Pd Thickness and Annealing Temperature on the Fabrication and Evolution of Palladium Nanostructures on Si (111) via the Solid State Dewetting

Abstract: Abstract Si-based optoelectronic devices embedded with metallic nanoparticles (NPs) have demonstrated the NP shape, size, spacing, and crystallinity dependent on light absorption and emission induced by the localized surface plasmon resonance. In this work, we demonstrate various sizes and configurations of palladium (Pd) nanostructures on Si (111) by the systematic thermal annealing with the variation of Pd thickness and annealing temperature. The evolution of Pd nanostructures are systematically controlled by the dewetting of thin film by means of the surface diffusion in conjunction with the surface and interface energy minimization and Volmer-Weber growth model. Depending on the control of deposition amount ranging between 0.5 and 100 nm at various annealing temperatures, four distinctive regimes of Pd nanostructures are demonstrated: (i) small pits and grain formation, (ii) nucleation and growth of NPs, (iii) lateral evolution of NPs, and (iv) merged nanostructures. In addition, by the control of annealing between 300 and 800 °C, the Pd nanostructures show the evolution of small pits and grains, isolated NPs, and finally, Pd NP-assisted nanohole formation along with the Si decomposition and Pd-Si inter-diffusion. The Raman analysis showed the discrepancies on phonon modes of Si (111) such that the decreased peak intensity with left shift after the fabrication of Pd nanostructures. Furthermore, the UV-VIS-NIR reflectance spectra revealed the existence of surface morphology dependent on absorption, scattering, and reflectance properties.

Mujeres con pena privativa de libertad: ¿quiénes son y cómo viven en una cárcel de Ecuador?/  Women's imprisonment: Who they are and how they live in a prison in Ecuador?

Abstract:
Los estudios acerca de personas con pena privativa de libertad tradicionalmente han excluido en el análisis al grupo de mujeres presas bajo el argumento de su escaso número. Esta ausencia en el conocimiento motivó la realización del presente estudio que tiene como objetivo perfilar social y jurídicamente a mujeres recluidas en uno de los Centros de Rehabilitación Social ecuatorianos y, así mismo, conocer su forma de vida mientras cumplen condena, en la mayoría de casos, junto con sus hijos. El enfoque mixto en esta investigación permitió definir un diagnóstico coincidente con los planteamientos de la teoría del desarrollo sobre la delincuencia femenina. Los resultados permitieron ratificar que la falta de educación, el desempleo, la desestructuración familiar y la pobreza caracterizan mayoritariamente la realidad social de mujeres contraventoras de la ley y que los efectos adversos de las penas que cumplen trascienden los muros carcelarios y alcanzan sus redes familiares.

Abstract

Studies on people with custodial sentences have traditionally excluded in the analysis the group of women imprisoned under the argument of their limited number. This exclusion has motivated the development of the present study that as an objective wants to create a social and legal profile of women in one of the Ecuadorian Centers of Social Rehabilitation. This will help understand their daily life while in prison, which in major cases includes their life with their children. The emphasis of this investigation allows to define a diagnose that consists with the approaches of the theory of development of criminal activity by women. The results allowed to emphasise that the lack of education, employment, the destruction of families and the poverty is part of the social reality of the majority of women who break the law. The adversary effects of the jail sentences transcends prison walls and reaches the families of the women who are in prison.

Endoscopic Ultrasound-Guided Drainage of Intra-Abdominal Abscess after Gastric Perforation in a Patient Receiving Ramucirumab and Paclitaxel for Advanced Gastric Cancer

Abstract: Gastrointestinal perforation is a serious adverse event that occurs in approximately 1% of patients receiving ramucirumab and paclitaxel. A 67-year-old man with unresectable advanced gastric cancer was admitted to our hospital and treated with ramucirumab and paclitaxel. Gastric perforation occurred during the second cycle of chemotherapy. Although the patient’s condition improved without surgery, an abscess developed in the intra-abdominal fluid collection resulting from the perforation. We performed endoscopic ultrasound-guided abscess drainage. The patient improved and was discharged in satisfactory condition. Endoscopic ultrasound-guided drainage is a treatment option for patients with intra-abdominal abscess following gastric perforation due to ramucirumab.

An Integral Model to Provide Reactive and Proactive Services in an Academic CSIRT Based on Business Intelligence

Abstract: Cyber-attacks have increased in severity and complexity. That requires, that the CERT/CSIRT research and develops new security tools. Therefore, our study focuses on the design of an integral model based on Business Intelligence (BI), which provides reactive and proactive services in a CSIRT, in order to alert and reduce any suspicious or malicious activity on information systems and data networks. To achieve this purpose, a solution has been assembled, that generates information stores, being compiled from a continuous network transmission of several internal and external sources of an organization. However, it contemplates a data warehouse, which is focused like a correlator of logs, being formed by the information of feeds with diverse formats. Furthermore, it analyzed attack detection and port scanning, obtained from sensors such as Snort and Passive Vulnerability Scanner, which are stored in a database, where the logs have been generated by the systems. With such inputs, we designed and implemented BI systems using the phases of the Ralph Kimball methodology, ETL and OLAP processes. In addition, a software application has been implemented using the SCRUM methodology, which allowed to link the obtained logs to the BI system for visualization in dynamic dashboards, with the purpose of generating early alerts and constructing complex queries using the user interface through objects structures. The results demonstrate, that this solution has generated early warnings based on the level of criticality and level of sensitivity of malware and vulnerabilities as well as monitoring efficiency, increasing the level of security of member institutions.

The metabolic equivalents of one-mile walking by older adults; implications for health promotion

Abstract: Background: Instructions for older adults regarding the intensity of walking may not elicit an intensity to infer health gains. We recorded the metabolic equivalents (METs) during a 1-mile walk using constant and predicted values of resting MET in older adults to establish walking guidelines for health promotion and participation.Methods: In a cross-sectional design study, participants (15 men, 10 women) walked 1-mile over ground, in a wooden floored gymnasium, wearing the Cosmed K4b2 for measurement of energy expenditure. Constant or predicted values for resting MET were used to calculate the number of 1-mile walks to meet 450-750 MET∙min∙wk-1.Results: Participants had MET values higher than 3 for both methods, with 29% and 64% of the participants higher than 6 for a constant and predicted MET value, respectively. The METs of the1-mile walk were (mean ± SD) 6 ± 1 and 7 ± 1 METs using constant and predicted resting MET,and similar for men (constant: 6 ± 1 METs; predicted: 7 ± 1 METs) and women (constant: 5±1METs; predicted: 6 ± 1 METs) (P > 0.05).Conclusion: Older adults that are instructed to walk 1-mile at a fast and constant pace meet the minimum required intensity for physical activity, and public health guidelines. Health professionals, that administer exercise, could encourage older adults to accumulate between six and nine 1-mile walks per week for health gains.

Evaluation of microhardness of residual dentin in primary molars following caries removal with conventional and chemomechanical techniques: An In vitro Study

Abstract: Background: Many patients consider removal of caries to be a very unpleasant experience. Removal of caries with conventional drill is considered traumatic mainly due to fear and anxiety of children and their parents. Minimally invasive dentistry adopts a philosophy that integrates prevention, remineralization, and minimal intervention for the placement and replacement of restorations, thus reaching the treatment objective using the least invasive surgical approach, with the removal of the minimal amount of healthy tissues. Chemomechanical caries removal (CMCR) is a method for minimally invasive, gentle dentin caries removal based on biological principles which is an effective alternative to the traditional method. The present study was done to compare the microhardness of sound dentin before and after carious removal using a chemomechanical method and a conventional method. Materials and Methods: The present in vitro study was done on 28 proximal surfaces of fourteen extracted primary molars (with active caries on one proximal surface and sound side as control). The study was done to assess the Knoop microhardness of remaining dentinal surface after caries removal using a slow speed conventional bur and a chemomechanical method (Carie-Care™). Results and Conclusion: The rotary instrument group showed a consistent microhardness value with not much difference according to depth. The chemomechanical group showed a lesser microhardness value closer to the cavity floor than away from it. The microhardness values at all depths were significantly different for each treatment group with an increased value seen in the rotary group. The mean microhardness values of residual dentin in treated side were found to be insignificant when compared among each interval in each group. The microhardness of sound dentin had high significant difference from that of residual dentin in both the rotary group and the chemomechanical group.

Epitope Sequences in Dengue Virus NS1 Protein Identified by Monoclonal Antibodies

Abstract: Dengue nonstructural protein 1 (NS1) is a multi-functional glycoprotein with essential functions both in viral replication and modulation of host innate immune responses. NS1 has been established as a good surrogate marker for infection. In the present study, we generated four anti-NS1 monoclonal antibodies against recombinant NS1 protein from dengue virus serotype 2 (DENV2), which were used to map three NS1 epitopes. The sequence 193AVHADMGYWIESALNDT209 was recognized by monoclonal antibodies 2H5 and 4H1BC, which also cross-reacted with Zika virus (ZIKV) protein. On the other hand, the sequence 25VHTWTEQYKFQPES38 was recognized by mAb 4F6 that did not cross react with ZIKV. Lastly, a previously unidentified DENV2 NS1-specific epitope, represented by the sequence 127ELHNQTFLIDGPETAEC143, is described in the present study after reaction with mAb 4H2, which also did not cross react with ZIKV. The selection and characterization of the epitope, specificity of anti-NS1 mAbs, may contribute to the development of diagnostic tools able to differentiate DENV and ZIKV infections.

FK866 attenuates acute hepatic failure through c-jun-N-terminal kinase (JNK)-dependent autophagy

Abstract: Abstract FK866 exhibits a protective effect on D-galactosamine (GaIN)/lipopolysaccharide (LPS) and concanavalin A (ConA)-induced acute liver failure (ALF), but the mechanism by which FK866 affords this benefit has not yet been elucidated. Autophagy has a protective effect on acute liver injury. However, the contribution of autophagy to FK866-conferred hepatoprotection is still unclear. This study aimed to investigate whether FK866 could attenuate GaIN/LPS and ConA-induced ALF through c-jun-N-terminal kinase (JNK)-dependent autophagy. In vivo, Mice were pretreated with FK866 at 24, 12, and 0.5 h before treatment with GaIN/LPS and ConA. 3-methyladenine (3MA) or rapamycin were used to determine the role of autophagy in FK866-conferred hepatoprotection. In primary hepatocytes, autophagy was inhibited by 3MA or autophagy-related protein 7 (Atg7) small interfering RNA (siRNA). JNK was suppressed by SP600125 or Jnk siRNA. FK866 alleviated hepatotoxicity and increased autophagy while decreased JNK activation. Suppression of autophagy abolished the FK866-conferred protection. Inhibition of JNK increased autophagy and exhibited strongly protective effect. Collectively, FK866 could ameliorate GaIN/LPS and ConA-induced ALF through induction of autophagy while suppression of JNK. These findings suggest that FK866 acts as a simple and applicable preconditioning intervention to protect against ALF; autophagy and JNK may also provide therapeutic targets for ALF treatment.

C3a Enhances the Formation of Intestinal Organoids through C3aR1

Abstract: C3a is important in the regulation of the immune response as well as in the development of organ inflammation and injury. Furthermore, C3a contributes to liver regeneration but its role in intestinal stem cell function has not been studied. We hypothesized that C3a is important for intestinal repair and regeneration. Intestinal organoid formation, a measure of stem cell capacity, was significantly limited in C3-deficient and C3a receptor (C3aR) 1-deficient mice while C3a promoted the growth of organoids from normal mice by supporting Wnt-signaling but not from C3aR1-deficient mice. Similarly, the presence of C3a in media enhanced the expression of the intestinal stem cell marker leucine-rich repeat G-protein-coupled receptor 5 (Lgr5) and of the cell proliferation marker Ki67 in organoids formed from C3-deficient but not from C3aR1-deficient mice. Using Lgr5.egfp mice we showed significant expression of C3 in Lgr5+ intestinal stem cells whereas C3aR1 was expressed on the surface of various intestinal cells. C3 and C3aR1 expression was induced in intestinal crypts in response to ischemia/reperfusion injury. Finally, C3aR1-deficient mice displayed ischemia/reperfusion injury comparable to control mice. These data suggest that C3a through interaction with C3aR1 enhances stem cell expansion and organoid formation and as such may have a role in intestinal regeneration.

Fabrication and Properties of Iron-based Soft Magnetic Composites Coated with NiZnFe2O4

Abstract: This paper focuses on iron-based soft magnetic composites which were synthesized by utilizing the sol-gel method prepared Ni-Zn ferrite particles as insulating compound to coat iron powder, and the influence of NiZnFe2O4 content and molding pressure on the magnetic properties was studied. The morphology, magnetic properties and density of Ni-Zn ferrite insulated compacts were investigated. Scanning electron microscope,line-scan EDX analysis and distribution maps show that the iron particle surface is covered with a thin layer of uniform Ni-Zn ferrites. The existing of the insulating layer can effectively improve the electrical resistivity of soft magnetic composites. Magnetic measurements show that the real part of permeability decreases with the increase of the Ni-Zn ferrite content, and the sample with 3%(mass fraction, the same below) Ni-Zn ferrite has an acceptable real part and minimum imaginary part of permeability in comparison with other samples. Results show that the addition of NiZnFe2O4 can dramatically decrease the internal magnetic loss, the magnetic loss of coated samples decreases by 83.8% as compared with that of uncoated samples at 100kHz. The density of the Fe-3%NiZnFe2O4 compacts reaches 7.14g/cm3 and the saturation magnetization is 1.47T when the molding pressure is 1000MPa.

« Peuples des Balkans, fédérez‑vous ! » : projets pour une résolution pacifique de la question d’Orient au tournant du xxe siècle

Abstract: Throughout the 19th century, pacifist solutions to the disputes between communities or States in the Balkans, had been coined along with nationalist, militarist and expansionist answers. Formulated and elaborated by a series of individual and institutional actors, these solutions were mainly built upon a federalisation project for the Balkan space. The idea for the creation of a Federal Republic, goes back to the end of the 18th century and it reappeared at various times, during the crisis that punctuated the Eastern question, till the attempt for the constitution of a Balkan confederation by French socialist Paul Argyriadis, as well as other European federalists/pacifists at the end of the 19th century. At the eve of the 1912‑1913 conflicts which caused an upheaval to the European ottoman possessions, or in front of the bellicist threats as a result of the outbreak of the Great War, new initiatives aiming at the organisation of a Balkan federation, had been undertaken by socialist parties or movements in the region; they were led by personalities such as Abraham Benaroya, Dragiša Lapčević, Christian Rakovski and Yanko Sakazov.

Measuring stigma affecting sex workers (SW) and men who have sex with men (MSM): A systematic review.

Abstract:
Background
Stigma involves discrediting a person or group based on a perceived attribute, behaviour or reputation associated with them. Sex workers (SW) and men who have sex with men (MSM) are key populations who are often at increased risk for the acquisition and transmission of HIV and who are affected by stigma that can negatively impact their health and well-being. Although stigma was included as an indicator in the US National HIV/AIDS Strategic Plan and there have been consultations focused on adding a stigma indicator within PEPFAR and the Global Fund in relation to potentiating HIV risks among key populations, there remains limited consensus on the appropriate measurement of SW- or MSM-associated stigma. Consequently, this systematic review summarizes studies using quantitative, qualitative, or mixed methods approaches to measure stigma affecting sex workers and men who have sex with men.
Methods and findings
This systematic review included English, French, and Spanish peer-reviewed research of any study design measuring SW- or MSM-associated stigma. Articles were published from January 1, 2004 to March 26, 2014 in PsycINFO, PubMed, EMBASE, CINAHL Plus, Global Health, and World Health Organization Global Health Library Regional Indexes. Of the 541 articles reviewed, the majority measured stigma toward MSM (over 97%), were conducted in North America, used quantitative methods, and focused on internalized stigma.
Conclusions
With the inclusion of addressing stigma in several domestic and international HIV strategies, there is a need to ensure the use of validated metrics for stigma. The field to date has completed limited measurement of stigma affecting sex workers, and limited measurement of stigma affecting MSM outside of higher income settings. Moving forward requires a concerted effort integrating validated metrics of stigma into health-related surveys and programs for key populations.

Future Protein Supply and Demand: Strategies and Factors Influencing a Sustainable Equilibrium

Abstract: A growing global population, combined with factors such as changing socio-demographics, will place increased pressure on the world’s resources to provide not only more but also different types of food. Increased demand for animal-based protein in particular is expected to have a negative environmental impact, generating greenhouse gas emissions, requiring more water and more land. Addressing this “perfect storm” will necessitate more sustainable production of existing sources of protein as well as alternative sources for direct human consumption. This paper outlines some potential demand scenarios and provides an overview of selected existing and novel protein sources in terms of their potential to sustainably deliver protein for the future, considering drivers and challenges relating to nutritional, environmental, and technological and market/consumer domains. It concludes that different factors influence the potential of existing and novel sources. Existing protein sources are primarily hindered by their negative environmental impacts with some concerns around health. However, they offer social and economic benefits, and have a high level of consumer acceptance. Furthermore, recent research emphasizes the role of livestock as part of the solution to greenhouse gas emissions, and indicates that animal-based protein has an important role as part of a sustainable diet and as a contributor to food security. Novel proteins require the development of new value chains, and attention to issues such as production costs, food safety, scalability and consumer acceptance. Furthermore, positive environmental impacts cannot be assumed with novel protein sources and care must be taken to ensure that comparisons between novel and existing protein sources are valid. Greater alignment of political forces, and the involvement of wider stakeholders in a governance role, as well as development/commercialization role, is required to address both sources of protein and ensure food security.

Anti-inflammatory activity of two varieties of pumpkin seed oil in an adjuvant arthritis model in rats

Abstract: The aim of the present research was to evaluate the anti-inflammatory activity of pumpkin seed oils (PSOs) of an Egyptian and European variety, in a rat model of adjuvant arthritis. Edema thickness, plasma tumor necrosis factor-α (TNF-α) and erythrocyte sedimentation rate (ESR) were determined as inflammatory biomarkers while malondialdehyde (MDA) and total antioxidant capacity (TAC) were assessed as indicative of oxidative stress. Chromosomal aberration, sperm shape abnormalities, and DNA fragmentations are cytogenetic parameters which aid in tracing inflammatory and oxidative activity. Phenolic contents and β-carotene were determined in PSOs. The results showed elevated ESR, plasma TNF-α, plasma MDA, liver cellular DNA fragmentation, bone marrow chromosomal aberration, sperm shape abnormalities with a reduction in plasma TAC and body weight gain in an adjuvant arthritis control compared to a healthy control. Administration of low and high doses of either Egyptian or European PSO improved all the aforementioned parameters with variable degrees.

The effect of 8 weeks of whole body vibration training on static balance and explosive strength of lower limbs in physical education students

Abstract: Background: It has been shown that whole body vibration training has an effect on strength and balance in athletes of various sports.Objective: The purpose of the study was to examine the effect of 8 weeks of Whole Body Vibration (WBV) training on static balance and explosive strength of the lower limbs, using two different training intensities vibration protocols.Methods: Eighty-three physical education students (age 19.39 ± 2.35 years) volunteered to participate in an 8-week WBV training. They were randomly divided into two groups with 30 sec and 60 sec duration of vibration exposure per exercise, total volume of exercise was the same for both groups. The explosive strength of the lower limbs was assessed by a squat jump and static balance by Balance Error Scoring System at the baseline (pre-test) and after 8 weeks of WBV training at 15 sec, 5, 10, and 15 min after the end of WBV exposure. A two-way ANOVA 2 × 5 (protocol × time) with repeated measures on both factors was used. Univariate analyses with simple contrasts across time were selected as post hoc tests.Results: Results showed a time × protocol interaction effect for static balance (p < .001) but not for the squat jump (p > .05). Furthermore, a time effect was found for the static balance and squat jump test. The 60 sec protocol had a greater percentage improvement compared to the 30 sec protocol in static balance (p = .003), whereas the 30 sec protocol was superior to the 60 sec protocol in explosive strength. However, the differences between the two protocols were not significant.Conclusion: WBV training had positive effects on static balance and explosive strength in physical education students. Balance and jump performance may benefit from WBV training. Therefore, WBV may be an effective training method for the improvement of static balance and lower limb strength.

Free piston linear generator for low grid power generation

Abstract: Generating power is of great importance nowadays across the world. However, recently, the world became aware of the climatic changes due to the greenhouse effect caused by CO2 emissions and began seeking solutions to reduce the negative impact on the environment. Besides, the exhaustion of fossil fuels and their environmental impact, make it is crucial to develop clean energy sources, and efforts are focused on developing and improving the efficiency of all energy consuming systems. The tubular permanent magnet linear generators (TPMLGs) are the best candidate for energy converters. Despite being suffering problem of attraction force between permanent magnets and stator teeth, to eliminate such attraction force, ironless-stator could be considered. Thus, they could waive the presence of any magnetic attraction between the moving and stator part. This paper presents the design and analysis of ironless -cored TPMLG for low grid power generation. The main advantages of this generator are the low cogging force and high efficiency. Therefore, the magnetic field computation of the proposed generator has been performed by applying a magnetic vector potential and utilizing a 2-D finite element analysis (FEA). Moreover, the experimental results for the current profile, pressure profile and velocity profile have been presented.

Management of Ureters Involved in Inguinal Hernias

Abstract:
Background: The presence of a ureter in a hernia sac presents a unique surgical challenge and can increase the likelihood of ureteral injury at the time of surgery as they are often not identified pre-operatively. Here we present our institutional experience and thorough systematic review in order to provide guidance on the urologist’s role in this situation.

Materials and Methods: A PubMed and Medline search was conducted to identify relevant literature published in the year 2000 or later. Case reports and case series in the English language were included using terms “ureter and hernia”, “herniated ureter”, “ureteral hernia”, inguinal hernia and ureter”.

Results: The presence of a ureter in an inguinal hernia sac is an uncommon finding. When present, many are not identified pre-operatively, which places the patient at risk for ureteral injury during herniorrhaphy.Patients with ureters contained in their inguinal hernias, that were identified pre-operatively or intra-operatively and not injured, recovered well. Post-operative imaging, when performed, showed stabilization or improvement of hydronephrosis and a more normal course of the ureter. One case reported the identification of ureteral involvement post-operatively after injury, which resulted in worsened renal function and required a re-operation.

Conclusions:The presence of a ureter in an inguinal hernia can be differently managed. The primary goal should be avoidance of injury intra-operatively.

Мигранты и Российское государство в XX веке: возможности и ограничения

Abstract: Статья продолжает тему «самовольных мигрантов», поднятую Л. Сигельбаумом и Л. П. Мох в работе “Escaping in Twentieth-Century Russia”. По мнению автора, Российское государство в течение большей части XX столетия наиболее остро реагировало на нарушения политического режима, часто предпочитая не замечать экономическую миграцию. Это происходило из-за тщательно скрываемой неспособности власти тотально контролировать население. Нарушения режима территориальных перемещений индивидуальными мигрантами были возможны по причине несогласованных действий центральных и местных органов власти. По мере постепенной либерализации советской системы во второй половине XX в. у мигрантов появлялось все больше возможностей для легальных перемещений. Отказ от силового регулирования миграционных потоков, вытеснение политического фактора в миграциях экономических привели к сужению пространства «самовольности».

Social Security and Fighting Poverty in Tunisia

Abstract: The objective of this study was to examine the role of social security in fighting poverty in Metlaoui, Tunisia, using survey data collected between July 2012 and January 2014, covering 200 poor households. We used questionnaire data, which gave a thorough analysis of the reactions, behavior, and strategies adopted by poor households as a result of various forms of risk. Social security has an effect on a number of different areas, including health, education, housing, and income. Our methodology explored both complete and partial risk-sharing, to investigate the impact of social security schemes on the strategies adopted by households to cope with economic shocks. The estimation results of different models showed that social security could help social security-covered households choose less costly strategies to cope with risks. However, the role of social security remains insufficient, given that covered households had less confidence in its services and they adopted strategies of self-insurance or income smoothing. Overall, the results showed that social security plays an important role in Metlaoui, but it remains insufficient, especially for households that are not covered by social security and are suffering from heavy health expenditures.


Variation in TMEM106B in chronic traumatic encephalopathy

Abstract: Abstract The genetic basis of chronic traumatic encephalopathy (CTE) is poorly understood. Variation in transmembrane protein 106B (TMEM106B) has been associated with enhanced neuroinflammation during aging and with TDP-43-related neurodegenerative disease, and rs3173615, a missense coding SNP in TMEM106B, has been implicated as a functional variant in these processes. Neuroinflammation and TDP-43 pathology are prominent features in CTE. The purpose of this study was to determine whether genetic variation in TMEM106B is associated with CTE risk, pathological features, and ante-mortem dementia. Eighty-six deceased male athletes with a history of participation in American football, informant-reported Caucasian, and a positive postmortem diagnosis of CTE without comorbid neurodegenerative disease were genotyped for rs3173615. The minor allele frequency (MAF = 0.42) in participants with CTE did not differ from previously reported neurologically normal controls (MAF = 0.43). However, in a case-only analysis among CTE cases, the minor allele was associated with reduced phosphorylated tau (ptau) pathology in the dorsolateral frontal cortex (DLFC) (AT8 density, odds ratio [OR] of increasing one quartile = 0.42, 95% confidence interval [CI] 0.22–0.79, p = 0.008), reduced neuroinflammation in the DLFC (CD68 density, OR of increasing one quartile = 0.53, 95% CI 0.29–0.98, p = 0.043), and increased synaptic protein density (β = 0.306, 95% CI 0.065–0.546, p = 0.014). Among CTE cases, TMEM106B minor allele was also associated with reduced ante-mortem dementia (OR = 0.40, 95% CI 0.16–0.99, p = 0.048), but was not associated with TDP-43 pathology. All case-only models were adjusted for age at death and duration of football play. Taken together, variation in TMEM106B may have a protective effect on CTE-related outcomes.

Behavior Responses to Chemical and Optogenetic Stimuli in Drosophila Larvae

Abstract: An animal’s ability to navigate an olfactory environment is critically dependent on the activities of its first-order olfactory receptor neurons (ORNs). While considerable research has focused on ORN responses to odorants, the mechanisms by which olfactory information is encoded in the activities of ORNs and translated into navigational behavior remain poorly understood. We sought to determine the contributions of most Drosophila melanogaster larval ORNs to navigational behavior. Using odorants to activate ORNs and a larval tracking assay to measure the corresponding behavioral response, we observed that larval ORN activators cluster into four groups based on the behavior responses elicited from larvae. This is significant because it provides new insights into the functional relationship between ORN activity and behavioral response. Subsequent optogenetic analyses of a subset of ORNs revealed previously undescribed properties of larval ORNs. Furthermore, our results indicated that different temporal patterns of ORN activation elicit different behavioral outputs: some ORNs respond to stimulus increments while others respond to stimulus decrements. These results suggest that the ability of ORNs to encode temporal patterns of stimulation increases the coding capacity of the olfactory circuit. Moreover, the ability of ORNs to sense stimulus increments and decrements facilitates instantaneous evaluations of concentration changes in the environment. Together, these ORN properties enable larvae to efficiently navigate a complex olfactory environment. Ultimately, knowledge of how ORN activity patterns and their weighted contributions influence odor coding may eventually reveal how peripheral information is organized and transmitted to subsequent layers of a neural circuit.

Water mites (Acari, Hydrachnidia) of riparian springs in a small lowland river valley: what are the key factors for species distribution?

Abstract: This paper examines the impact of disturbance factors—flooding and intermittency—on the distribution of water mites in the riparian springs situated in the valley of a small lowland river, the Krąpiel. The landscape factors and physicochemical parameters of the water were analysed in order to gain an understanding of the pattern of water mite assemblages in the riparian springs. Three limnological types of springs were examined (helocrenes, limnocrenes and rheocrenes) along the whole course of the river and a total of 35 water mite species were found. Our study shows that flooding influences spring assemblages, causing a decrease in crenobiontic water mites in flooded springs. The impact of intermittency resulted in a high percentage of species typical of temporary water bodies. Surprisingly, the study revealed the positive impact of the anthropogenic transformation of the river valley: preventing the riparian springs from flooding enhances the diversity of crenobiontic species in non-flooded springs. In the conclusion, our study revealed that further conservation strategies for the protection of the riparian springs along large rivers would take into account ongoing climatic changes and possible the positive impact of the anthropogenic transformation of river valleys.

Dielectric and impedance spectroscopic studies of three phase graphene/titania/poly(vinyl alcohol) nanocomposite films

Abstract: Flexible dielectric polymer composites with high dielectric permittivity and low dielectric loss have many applications in different areas of electronic industry. In this paper, we propose synthesis of flexible dielectric materials with efficient dielectric properties. We increased dielectric efficiency of poly(vinyl alcohol) by reinforcement of conducting graphene and rutile titania fillers in different weight fractions. The superiority of this method is that synthesized three phase graphene/titania/poly(vinyl alcohol) nanocomposite films have high dielectric permittivity, low dielectric loss and are flexible. Our results show that graphene/titania/poly(vinyl alcohol) with weight/weight fraction of 3:20:100 bears dielectric permittivity of 330 at 20 Hz that is about 36 times larger than that of neat PVA at same frequency. At this frequency above mentioned graphene/titania/poly(vinyl alcohol) nanocomposite has loss tangent of 4.39 acceptable for dielectrics in embedded capacitors and AC conductivity of 1.6 × 10−6 Sm−1 that is much greater than that of neat PVA i.e; 6.5 × 10−9 Sm−1. Complex impedance spectroscopy, complex electric modulus and Cole-Cole plots of synthesized graphene/titania/poly(vinyl alcohol) nanocomposite films further confirm its better capacitive performance. Keywords: Ceramics, Polymer, Dielectric response, Impedance spectroscopy, AC conductivity

A Robust Information Life Cycle Management Framework for Securing and Governing Critical Infrastructure Systems

Abstract: In modern societies, the rampant growth of the Internet, both on the technological and social level, has created fertile ground for the emergence of new types of risk. On top of that, it enhances pre-existing threats by offering new means for accessing and exploiting Critical Infrastructures. As the kinds of potential threats evolve, the security, safety and resilience of these infrastructures must be updated accordingly, both at a prevention, as well as a real-time confrontation level. Our research approaches the security of these infrastructures with a focus on the data and utilization of every possible piece of information that derives from this ecosystem. Such a task is quite daunting, since the quantity of data that requires processing resides in the Big Dataspace. To address this, we introduce a new well-defined Information Life Cycle in order to properly model and optimise the way information flows through a modern security system. This life cycle covers all the possible stages, starting from the collection phase up until the exploitation of information intelligence. That ensures the efficiency of data processing and filtering while increasing both the veracity and validity of the final outcome. In addition, an agile Framework is introduced that is optimised to take full advantage of the Information Life Cycle. As a result, it exploits the generated knowledge taking the correct sequence of actions that will successfully address possible threats. This Framework leverages every possible data source that could provide vital information to Critical Infrastructures by performing analysis and data fusion being able to cope with data variety and variability. At the same time, it orchestrates the pre-existing processes and resources of these infrastructures. Through rigorous testing, it was found that response time against hazards was dramatically decreased. As a result, this Framework is an ideal candidate for strengthening and shielding the infrastructures’ resilience while improving management of the resources used.

Efficient and Memory Saving Method Based on Pseudoskeleton Approximation for Analysis of Finite Periodic Structures

Abstract: An efficient and memory saving method based on pseudoskeleton approximation (PSA) is presented for the effective and accurate analysis of finite periodic structures. Different from the macro basis function analysis model, our proposed method uses the formulations derived by the local Rao-Wilton-Glisson basis functions. PSA is not only used to accelerate the matrix-vector product (MVP) inside the single unit but also adopted to decrease the calculation burden of the coupling between the different cells. Moreover, the number of decomposed coupling matrices is minimized due to the displacement invariance of the periodic property. Consequently, even compared with the multilevel fast multipole algorithm (MLFMA), the new method saves much more memory resources and computation time, which is also demonstrated by the numerical examples.

Influence of the nutrient medium and the spectral composition of light on the reproduction of strawberry in vitro

Abstract: The research was conducted in 2016-2017 on the basis of a meristem laboratory. Object of the research is the micro-shoots of garden strawberry the Festival variety and remontant strawberry the Brighton variety at the stages of micropropagation and rooting. The following nutrient media were studied: Murashige and Skoog (control), Murashige and Skoog modified (microelements were replaced with a corresponding dose of microfertilizer “Siliplant”) and Boxyu; LED irradiators - with a ratio in the spectrum of red, blue and white light R2: B1:W1 and R1: B1: W1, respectively, and a programmable one with a changing spectrum. A luminescent lamp with white light served as the control. The highest rate of reproduction in the cultivation of garden strawberry in vitro was obtained using the Murashige and Skoog culture medium under a LED irradiator with a R1: B1: W1 combination of red, blue and white light and the irradiator with a changing spectral composition: 6.0 and 6.2 pieces/microcutting, respectively. The highest reproduction factor of remontant strawberry was provided by cultivation on the Murashige and Skoog nutrient medium using the LED light irradiator in ratio of red, blue and white as R1:B1:W1 and the irradiator with a changing spectral composition: 3.5 and 3.2 pieces / microcutting, respectively. A rooting of micro-shoots of garden strawberry on the modified Murashige and Skoog nutrient medium and Boxyu provided a significant increase in rooting ability to 100% and 97.5%, respectively. Cultivation on the Boxyu nutrient medium has increased the rooting ability of micro-shoots of remontant strawberry to 95.0%. All the LED irradiators provided a significant increase in the rooting ability of micro-shoots: for garden strawberries - up to 96.6-100%, for remontant - up to 83.3-90.0%.

Preliminary screening of biostimulative effects of Göemar BM-86 on eggplant cultivars grown under field conditions in Poland

Abstract: Seaweed extracts are widely used in agriculture as ecological focus substances applied to improve crop growth and quality. One of the primary benefits they bring is increased effectiveness of fruit setting as well as improved stress tolerance, essential for warm-climate crops cultivated in the nonoptimal environmental conditions of Northern and Central Europe. The aim of this study was a preliminary investigation of any genotype-dependent reaction of eggplant cultivars (Solanum melongena) to application of a standardized extract of the seaweed Ascophyllum nodosum (Göemar BM-86) under field conditions in Poland. The only statistically relevant result of this biostimulant was shown for cultivar ‘Flavine’ F1, where it positively affected the early crop yield and the number of fruits per plant. Fruit quality attributes, including antioxidant activity, as well as selected mineral contents, increased as an effect of biostimulant spraying. This reaction was specific for the cultivars investigated, and it was confirmed by significant differences in the main effects between biostimulant and control treatments for almost all the properties measured. The use of this A. nodosum extract suggested that there could be an improvement in fruit yield and quality in selected eggplant cultivars under field conditions in the temperate climatic zone.
