Anstract- While wireless technologies are common solutions to the last mile problem for IoT systems, challenges exist with devices that are in remote locations, sparse deployments, have power and cost constraints, and low data applications as the cost of wireless and the supporting infrastructure presents barriers to e... |
In summary, there are several ways to manage chronic pain with pharmacologic agents. The clinician should consider adjunctive agents such as antidepressants, stimulants, and antianxiety drugs as well as the standard narcotic analgesics. It is important to consider various modalities in treating the patient. A greater l... |
It is well established that aqueous solutions of methylcellulose (MC) can form hydrogels on heating, with the rheological gel point closely correlated to the appearance of optical turbidity. However, the detailed gelation mechanism and the resulting gel structure remain poorly understood. Herein the fibrillar structure... |
In recent years, indoor positioning has been getting a lot of attention. An indoor location method based on optimal dilution of precision of displacement vector components and factor of weighting adjustment with multiple array pseudolites is proposed to solve two problems that: 1) a single array pseudolite drops sharpl... |
The wide-use airport cement concrete direct-thickening double-deck pavement slabs (ACCDDPS) were selected as the research object to study their mechanical properties. The airport runway simulation test station (ARSTS) was used to conduct indoor tests to demonstrate the distribution of tension stress at the bottom of sl... |
The developmental cycle of a new species of Sarcocystis (S. neotomafelis) was investigated. Cysts obtained from the muscle fibers of the woodrats were given orally to 19 laboratory newborn kittens, 5 pups and 5 crotalids. Infection developed only in newborn kittens. Macrogametes, microgamonts and immature oocysts were ... |
OBJECTIVE |
To assess the feasibility of performing the C(1-2) transarticular screw fixation (Magerl's technique) for patients whose C(1-2) dislocation could not be reduced completely. |
METHODS |
Nineteen consecutive patients (from 2001 Feb. to 2003 Jan.) underwent bilateral C(1-2) transarticular screw fixation, 8 of which had an incompletely-reduced atlantoaxial dislocation. The patients' clinical outcomes within- and after-operation were evaluated, and the screws position and fixation conditions were studied ... |
RESULTS |
All the patients' symptoms had some improvement, no severe complications, such as injury of nerve or blood vessels, especially the vertebral arteries, were encountered. The screws were placed precisely, and purchased enough bone substance. Firm fixation obtained, no vertebral artery lesion occurred. |
CONCLUSION |
For the patients who have atlantoaxial dislocation that could not be reduced completely, if there is enough bone to contain the screw, performing bilateral transarticular screw fixation (Magerl technique) is still feasible and safe.Lifetime of biomolecules in polymer-based hybrid nanodevices |
Prolonging the lifetime of biomolecules in their functional states is critical for many applications where biomolecules are integrated into synthetic materials or devices. A simplified molecular shuttle system, which consists of fluorescently labelled microtubules propelled by kinesin motor proteins bound to the surfac... |
The previous chapters have displayed examples of partial differential equations in various fields of mathematical physics. Attention has been paid to the interpretation of these equations in the specific contexts they were presented. 1 In fact, we have delineated three types of field equations, namely hyperbolic, parab... |

The efficacy of a fenbendazole divided dose regime against immature stages of Trichonema spp, Strongylus vulgaris and Strongylus edentatus was evaluated. A group of 8 naturally infected 30 to 36-month-old ponies was divided into 2 equal groups on the basis of previous treatment and faecal egg counts, one group being tr... |
Industrial production of NH3 heavily depends on the conventional Haber-Bosch process under rigorous conditions with a large amount of energy consumption and carbon emissions. Electrocatalysis exhibits an intriguing prospect for the N2 reduction reaction (NRR) at ambient conditions. Wherein, a high-efficiency and low-co... |
In phaseless super-resolution, we only have the magnitude information of continuously-parameterized signals in a transform domain, and try to recover the original signals from these magnitude measurements. Optical microscopy is one application where the phaseless super-resolution for 2D signals arise. In this paper, we... |
The performance of 39 elderly subjects on three speech discrimination tasks, viz, CID W-22 word lists, the SPIN test and compressed SPIN sentence lists, was investigated. The effects of age and audiometric configuration on discrimination ability were examined, and age was found to significantly differentiate between su... |
OBJECTIVE |
The main objectives of this study were to describe the epidemiological characteristics, the associated factors and outcomes of extra-axial hematoma (EAH) in patients of traumatic brain injury (TBI) due to road traffic accident (RTA) and to assess their survival probability after 6 and 12 months to RTA. |
PATIENTS AND METHODS |
This was a retrospective record-based study. A total of 520 patients diagnosed with EAH due to RTA-related TBI were studied. This study covered ten years from January 1, 2010, to December 31, 2019. Descriptive statistics, including frequencies, percentages, mean, standard deviation, median and range were used. To test ... |
RESULTS |
EAH occurred in 42.1% of RTA-related TBI. Subdural hematoma (SDH) was the most common RTA-related EAH. Age and sex differences exist in the type of EAH with male preponderance and a significantly higher rate of SDH in patients aged 55 years or above. The total EHA mortality was 18.7%, and most occurred within the first... |
CONCLUSIONS |
Extra-axial hematomas are very common in RTA-related TBIs and have high mortality. SDH is the most common, tSAH had the highest mortality, while EDH has the best survival. Aggressive efforts are compulsory to reduce RTA-related TBI.[Effect of ginsenoside Rg1 on expressions of phosphory protein tau and N-methyl-D-aspart... |
OBJECTIVE |
To investigate the effect of ginsenoside Rg1 on the expressions of phosphory protein Tau (P-Tau), N-methyl-D-aspartate receptor subunit 1 (NR1) and N-methyl-D-aspartate receptor subunit 2B(NR2B) in rat brain slice model of Alzheimer's disease. |
METHOD |
Brains of 5-week-old Wistar rats were cut into slices which were 400 microm thick. These brain slices were randomly divided into normal control group, untreated group, low-dose ginsenoside Rg1 group, medium-dose ginsenoside Rg1 group and high-dose ginsenoside Rg1 group, with 10 slices in each group. All brain slices we... |
RESULT |
Compared with the normal control group, the expression of P-Tau was significantly increased (P < 0.05 or P < 0.01) and the expressions of NR1 and NR2B were decreased (P < 0.01) in untreated group. Compared with the untreated group, the expression of P-Tau was significantly decreased (P < 0.01 or P < 0.05) and the expre... |
CONCLUSION |
Ginsenoside Rg1 can play the role of anti-dementia by inhibiting the expression of P-Tau so as to slow the formation of neurofibrillary tangles and increasing the expression of NR1 and NR2B so as to improve learning and memory abilities in rat brain slice model of Alzheimer's disease.Re: "Treating Buccinator with Botul... |

It was previously reported that acylation of the N‐terminus of several known B2 antagonists with various types of bulky acyl groups consistently improved their antagonistic potency in the rat blood pressure assay. On the other hand, earlier results seem to suggest that the effects of acylation on the contractility of i... |
Repeated episodes of peritonitis cause malnutrition in CAPD patients because of increased protein loss into the dialysate, a high protein catabolic rate (PCR), and/or a decrease in appetite. The purpose of this study was to investigate whether protein supplements could improve the nutritional status of CAPD patients an... |
