The double crush hypothesis has not been rigorously evaluated in humans. We therefore analyzed cases of C6, C7, and C8 radiculopathy and exploited the fact that the median sensory response is of C6/C7 origin and the median motor response is primarily of C8 origin. We hypothesized that C6 and/or C7 cases would demonstrate an increased frequency of median mononeuropathy by sensory criteria, and C...

Fatal crush conditions occur in crowds with tragic frequency. Event organizers and architects are often criticised for failing to consider the causes and implications of crush, but the reality is that the prediction and mitigation of such conditions offers a significant technical challenge. Full treatment of physical force within crowd simulations is precise but computationally expensive; the m...

to evaluate the effects of local administration of the fetal brain extract (fbe) on the crushed peripheral nerve, 15 male wistar rats were used. the right sciatic nerve of 10 rats was locally underwent the tense compression for 30 seconds and then randomly divided into experimental and control (sham) groups. the remained rats were considered as intact animals. treatment was commenced weekly, by...

objective: the aim of present study was to evaluate the effects of oral administration of gallic acid (ga) for 21 days alone and in combination with exercise on nerve conduction velocity and sensory and motor functions in rats with sciatic nerve crush. materials and methods: seventy adult male wistar rats (250-300 g) were divided randomly into 7 groups with 10 in each: 1) control (cont), 2) cru...

Polyadenylated messenger RNA was isolated from goldfish retinas at various times following unilateral crush of the optic nerve. RNA was translated in a cell-free system and product proteins analyzed by two-dimensional gel electrophoresis and autofluorography. Poly(A)+ mRNA-directed protein synthesis revealed an 8-fold increase in the labeling of polypeptides of about 30 kd Mr and a pI of 5.5 in...

Limited optic nerve crush is a model of diffuse mechanical axon injury, the most prevalent cause of secondary neurodegeneration after closed head neurotrauma. In this report, a protocol is presented which allows for the rapid screening of differential gene expression in the inner retina, as well as the optic nerve, in response to partial nerve crush. To prove the reliability of the method, prot...

Introduction: The peripheral nervous system is remarkable in its ability to regenerate after injury because of a local permissive environment and activation of the neuronal intrinsic growth capacity. Local induction of inflammatory cytokines, which are produced by macrophages and Schwann cells, plays a crucial role in controlling Wallerian degeneration (WD) and nerve regeneration (1). Tumor nec...

The present study examined the temperament of 699 cows Aberdeen Angus cattle breed, reared in 14 farms Bulgaria. It was carried out within period 2017-2020. animals subject to were between two and eight years old. visually evaluated following a scoring system from 1 5. assessment method involved behavioural reaction upon manipulation, passing through chute fixation into crush. different systems...
