Acculturation seems to be positively associated with participation in leisure-time physical activity.[Acute Liver Failure, Acute-On-Chronic Liver Failure, Hepatorenal Syndrome, Hepatopulmonary Syndrome and Portopulmonary Hypertension, Artificial Liver Support on the ICU]. |
Background Acute hepatic dysfunction in the form of acute liver failure (ALF) or acute-on-chronic liver failure (ACLF) is a disease with a high risk of mortality and requires interdisciplinary intensive care. Aim This article explains the nomenclature, pathophysiology, prognosis and possible treatment options of ALF an... |
In an age of increasing complexity, simple answers no longer suffice, but the demand for greater sophistication is itself at odds with an era of growing specialization. Researchers must thus incorporate information from specialists in other fields. This trend in interdisciplinary research contains hidden challenges, ho... |
Mycobacterium aurum is considered a surrogate of M. tuberculosis and recently has been proposed as test organism in high throughput screening of antituberculosis drugs (3). In this investigation, we suggest use of a recombinant M. aurum expressing E. coli lacZ gene, in which beta-galactosidase production is the reporte... |
A-not-A refers to a Mandarin reduplication construction where the underlying form /RED-pu-A/ contains a reduplication of the first syllable in A. In this study I investigate the kinds of adaptations that occur when an English word serves as the base A in code-switching speech. Since the complex onsets and most codas al... |
Breeding redpoll finches (Aves: Carduelinae) show extensive plumage and size variability and, in many cases, a plumage polymorphism that is not related to age or sex. This has been ascribed to extreme phenotypic variation within a single taxon or to moderate variability within distinct taxa coupled with hybridization. ... |
We studied 15 resected cases with a history of apoplexy (2.5%) among 599 cases of esophageal cancer admitted between 1972 and 1993. Fourteen were male, and female, aged 48 to 77 years. Twelve had suffered from cerebral infarction, 2 intracerebral hemorrhage, and one subarachnoid hemorrhage. Duration from apoplexy to op... |
INTRODUCTION AND OBJECTIVE |
Conditions of a healthy, friendly and safe work environment and proper work organisation increase self-efficacy and decrease or eliminate the factors causing the occurrence of burnout symptoms, all of which have a decisive impact on increasing the quality of work. The aim of the study was to analyse and assess the infl... |
MATERIAL AND METHODS |
The study comprised randomly selected professionally-active nurses working on hospital wards (N=405) on the area of two provinces in Poland. The study used the Generalized Self-Efficacy Scale, Copenhagen Burnout Inventory and a questionnaire concerning the factors that influence the process of work organisation at nurs... |
RESULTS |
Lower scores for self-efficacy resulted in a worse assessment of development opportunities and promotion prospects (r=-0.11), participation in the decision-making process (r=-0.11) and teamwork (r=-0.10). Lower self-efficacy contributed to the occurrence of burnout symptoms r∈[-0.19 - -0.17]. |
CONCLUSIONS |
Properly shaped and used organisational factors are stimulating for professional efficiency and effectiveness, and consequently, for the quality of nursing work. Negative assessment of the factors in the work environment contributes to the occurrence of burnout symptoms and decrease in self-efficacy. Nurses with lower ... |
Background Impetigo is the most common skin infection in pediatric age and has the highest incidence increase relative to other skin infections observed in children. The reported incidences in the literature are between 1.65–2.8%, being evident a seasonal variation with peak of incidence during summer and autumn.The ai... |
The implementation of cervical cancer screening programs beginning in the 1950s is largely credited with a more than 70% reduction in cervical cancer deaths in the United States. In the decades since the introduction of these programs, the annual or biennial Papanicolaou (Pap) test has gained widespread accept-ance by ... |
Psychophysical thresholds and neuronal responses for isolated stimuli are strongly modified by nearby stimuli in the visual field. We studied the orientation and position specificity of these contextual interactions using a dual-frequency visual-evoked potential technique in developing human infants and adults. One set... |
We discuss necessary conditions for a Banach space to satisfy the property that its bounded sets are bounding in its bidual space. Apart from the classic case of co, we prove that, among others, the direct sum c 0 (l n 2 ) is another example of spaces having such property.Cleavage of a non-conserved target by a specifi... |
Micro RNAs (miRNAs) have emerged as an important class of gene expression regulators controlling development, growth and metabolism. These short RNA molecules are 20–24 nucleotides in length and act post-transcriptionally to regulate the cleavage or translation of specific mRNA targets. In the model legume Medicago tru... |
The Penrose tiling provides a prototype for the quasiperiodic crystal model of quasicrystals. We report results of Monte Carlo simulations of a two-dimensional model in which a Penrose tiling is the ground state. A single energy is assigned to any violation of the Penrose matching rules. Our results support the existen... |
LetX, Γbe Banach spaces and ^f\X^ Y, &\ Γ*-+X* be linear relations. Suppose ^f is a restriction of the adjoint (or preadjoint) ^* of & and the codimension of G(-$O in G(&*) is not necessarily finite. Under certain hypotheses we can describe in computational ly useful ways extensions ^ of sf which are restrictions of ^*... |
Business process improvement evaluation enables performance indicators to be used alongside process improvement techniques in order to quantitatively compare measurement information between the as-is and to-be processes. Limitations of the present methods of business process improvement indicate there is scope for look... |
ABSTRACT Streptococcus agalactiae is considered one of the major causes of bovine intramammary infections. It is also found in the vaginas of women without any apparent clinical symptoms, but reports of neonatal infections, causing significant morbidity, are relatively frequent. The aim of this study was to evaluate th... |
BACKGROUND |
Among patients with implanted cardiac implantable electronic device (CIED), ipsilateral upper extremity vein stenosis or occlusion (VSO) is observed more frequently than the in general population. However, there are no data available concerning relationship between hemostatic markers (and their dynamics) and occurrence... |
METHODS |
We performed a single-center, prospective study of consecutive first time CIED recipients. In an ultrasound examination before CIED implantation the presence of upper extremity VSO was excluded. Biochemical data were collected from all the patients before CIED implantation (first measuring), up to seven days (second me... |
RESULTS |
The study included 71 patients (mean age 73.1 + 10.5 years; 39 (55%) male). The incidence of VSO within 6-months follow up was 21.1%. Average concentrations of hemostatic markers increased significantly in all the patients immediately after CIED implantation. Serial hemostatic marker concentrations were similar in pati... |
CONCLUSION |
A significant increase in von Wilebrand factor concentration at six months post implantation may be a marker for VSO occurrence.[Primary lymphoma of the central nervous system: 20 years' experience in a referral hospital]. |
INTRODUCTION |
Primary central nervous system lymphomas (PCNSL) are rare neoplasms. AIM. To study the clinical aspects and the immuno-phenotype of all cases of PCNSL in a 20 years lapse in a referral hospital in Northeastern Mexico. |
PATIENTS AND METHODS |
From January 1986 to December 2005 all PCNSL histologically confirmed were studied. |
RESULTS |
The primary lymphomas were 1% of malignant central nervous system neoplasms. 21 cases were studied (ages from 9-70 years) with male predominance (2:1). 24% patients had immuno-suppression. The more frequent clinical data were: papilledema (71%), headache (62%), paresis (48%) and seizures (33%). 33% of patients died dur... |
CONCLUSIONS |
PCNSL are still a diagnostic challenge. Multicenter studies are required in order to determine the best treatment protocol.[Etiology, clinical picture, and diagnosis of postoperative peritonitis in rectal cancer]. |
Under analysis were 40 case histories and records of dissections of patients dead of diffuse peritonitis after operations for rectum cancer. It was established that in 1/3 of observations technical defects were responsible for peritonitis. Measures for the prevention of peritonitis are proposed when infection in the ab... |

The ossification of the cervical posterior longitudinal ligament (OPLL) is widely known and studied in Japan where a roentgenological incidence of 2.06% adults affected has been found. Data concerning the ossification of the lumbar posterior longitudinal ligament are few and occasional. An epidemiological survey on lum... |
The detection of airports using synthetic aperture radar (SAR) images has attracted considerable attention. Traditional methods easily result in inaccurate detection due to the complex scenes and multiplicative speckle noise. Therefore, airport detection from SAR images is still a challenging task. In order to limit th... |
BACKGROUND |
Converging neuroanatomic, neurophysiological, and neurobehavioral evidence implicate prefrontal subregions in schizophrenia. Neuroanatomic studies with magnetic resonance (MR) imaging enable regional volume parcellation. Inconsistent reports may relate to variable methods and small samples. We attempted to resolve volu... |
METHODS |
Magnetic resonance imaging was performed in 70 patients with schizophrenia (40 men and 30 women; 29 neuroleptic naive and 41 previously treated) and 81 healthy controls (34 men and 47 women). Gray and white matter volumes of the dorsolateral, dorsomedial, orbitolateral, and orbitomedial prefrontal cortex were quantifie... |
RESULTS |
Reduced prefrontal gray matter volume was observed in patients. The reduction was evident for the dorsolateral area in men (9%) and women (11%), for the dorsomedial area only in men (9%), and for orbital regions only in women (23% and 10% for lateral and medial, respectively). The reduction of orbital volume in women w... |
CONCLUSIONS |
Schizophrenia is associated with reduced gray matter volume in prefrontal cortex, which affects men and women in the dorsolateral sector. The effects are moderated by sex for dorsomedial and orbital regions and are related to symptom severity and cognitive function. This is not a by-product of treatment, since the diff... |
