Highly pathogenic H5N1 influenza A virus remains a substantial threat to public health. To understand the molecular basis and host mechanism for high virulence of viruses in mammals, we compared two isolates which have similar genetic backgrounds but greatly differ their mice. A/Chicken/Jiangsu/k0402/2010 (CK10) is highly pathogenic, whereas A/Goose/Jiangsu/k0403/2010 (GS10) nonpathogenic. We first showed that CK10 elicited more potent innate immune response than did GS10 mouse lungs by...

The surface electromyography (sEMG) signal has been used for volitional control of robotic assistive devices. There are still challenges in improving system performance accuracy and processing to remove systematic noise. A sEMG-controlled ambulation exoskeleton was developed this study, aiming achieve harmonic interactions between a user the system. gait cycle duration (GCD) extracted from sEMG signals using autocorrelation algorithm Bayesian redundant fusion algorithm. GCDs various walking...

Cervical facet joints are implicated as a major source of pain after whiplash injury. The purpose this study was to investigate the proposed capsule strain injury mechanism using neurophysiologic methods. Strain thresholds, threshold distribution, saturation strains and afterdischarge responses neural receptors were characterized in vivo. Goat C5-C6 joint capsules used identify characterize response controlled uniaxial stretch by recording C6 dorsal rootlet nerve discharge. stretched at 0.5...

This study investigates the functional and structural responses of spinal nerve roots in vivo to various strains strain rates. Seventy-two L5 dorsal from male Sprague-Dawley rats were each subjected a predetermined (<10%, 10-20%, >20%; n = 8) rate (0.01 mm/sec, 1 or 15 mm/sec; 24). Neurophysiologic recordings performed before after stretch determine changes conduction velocity (CV), amplitude, area compound action potential (CAP). Morphological injury as evident by primary secondary axotomy...

Accurate assessment of Newcastle disease virus (NDV) antibody titers is crucial for effective poultry control and surveillance. This article introduces an optimized method preparing 4 hemagglutination units (4-HAU) antigen solution, a key component the inhibition assay (HI) used in NDV serological detection. Unlike conventional methods, which involve time-consuming undefined back-titration adjustment steps, this approach streamlines process by accurately measuring HA titer using initial...

Background: Reverse total shoulder arthroplasty (RSA) increases deltoid muscle fiber recruitment and tension to compensate for deficient rotator cuff activity; however, it is unclear whether the anterior or middle becomes dominant how activation profile changes postoperatively. Using minimally invasive electromyography, this study evaluated activity of surrounding muscles during motion assess post-RSA. Methods: In observational study, we assessed change in preoperative postoperative 10...

Background: Concerns exist regarding potential complications associated with injectable cosmetic treatments for lying ear correction. This study aimed to examine the blood vessel distribution patterns in and face related filler procedures surgeries by using three-dimensional computed tomography angiography of cadaveric head specimens. Methods: In total, 50 high-resolution images lateral aspects specimens were captured. Three-dimensional vessels cephalo-auricular sulcus created Mimics. The...

Traumatic brain injury (TBI) continues to be a major health problem, with over 500,000 cases per year societal cost of approximately $85 billion in the US. Motor vehicle accidents are leading cause such injuries. In many TBI widespread disruption axons occurs through process known as diffuse axonal (DAI) or traumatic (TAI). current study, an vivo TAI model was developed using spinal nerve roots adult rats. This used determine functional and structural responses various strains displacement...

In Brief Study Design. To establish a methodology for the neurophysiologic study of mechanoreceptors in cervical facet joint capsule.
