REVIEW
Nitish Boodhoo, Angila Gurung, Shayan Sharif, Shahriar Behboudi
Marek's disease (MD), caused by Marek's disease virus (MDV), is a commercially important neoplastic disease of poultry which is only controlled by mass vaccination. Importantly, vaccines that can provide sterile immunity and inhibit virus transmission are lacking; such that vaccines are only capable of preventing neuropathy, oncogenic disease and immunosuppression, but are unable to prevent MDV transmission or infection, leading to emergence of increasingly virulent pathotypes. Hence, to address these issues, developing more efficacious vaccines that induce sterile immunity have become one of the important research goals for avian immunologists today...

BACKGROUND: Following neuropathy α2-adrenoceptor-mediated diffuse noxious inhibitory controls (DNIC), whereby a noxious conditioning stimulus inhibits the activity of spinal wide dynamic range (WDR) neurons, are abolished, and spinal 5-HT7 receptor densities are increased. Here, we manipulate spinal 5-HT content in spinal nerve ligated (SNL) animals and investigate which 5-HT receptor mediated actions predominate. METHODS: Using in vivo electrophysiology we recorded WDR neuronal responses to von frey filaments applied to the hind paw before, and concurrent to, a noxious ear pinch (the conditioning stimulus) in isoflurane-anaesthetised rats...

Hearing is an essential sense for communication in animals and humans. Normal function of the cochlea of higher vertebrates relies on a fine-tuned interplay of afferent and efferent innervation of both inner and outer hair cells. Efferent inhibition is controlled via olivocochlear feedback loops, mediated mainly by acetylcholine, γ-aminobutyric acid (GABA) and glycine, and is one of the first sites affected by synapto- and neuropathy in the development of hearing loss. While the functions of acetylcholine, GABA, and other inhibitory transmitters within these feedback loops are at least partially understood, especially the function of glycine still remains elusive...

BACKGROUND: There are currently no promising therapies available to treat or prevent peripheral neuropathy (PN) induced by anticancer drugs in a cumulative dose-dependent manner. In this study, we investigated the efficacy of regional cooling of hands and feet in preventing paclitaxel (PTX)-induced PN. METHODS: Patients with gynecologic cancer who received a tri-weekly cycle of chemotherapy including PTX at doses of 150-175 mg/m(2) were included in this study. Regional cooling was performed by covering patient hands and feet with cold insulators during PTX administration (regional cooling group)...

Glaucoma is an irreversible and blinding neurodegenerative disease of the eye, and is characterized by progressive loss of retinal ganglion cells (RGCs). Since endogenous hydrogen sulfide (H2S) was reported to be involved in neurodegeneration in the central nervous system, the authors aimed to develop a chronic ocular hypertension (COH) rat model simulating glaucoma and therein test the H2S level together with the retinal protein expressions of related synthases, and further investigated the effect of exogenous H2S supplement on RGC survival...

PURPOSE: Chemotherapy-induced peripheral neuropathy (CIPN) is an issue for both cancer patients and specialists, and the number of cases of CIPN is growing with the increasing number of cancer patients worldwide. CIPN is often caused by common anticancer drugs such as taxanes and platinum analogs. These are key drugs for various cancers including colorectal and gastric cancers. However, there are currently no effective drugs to prevent CIPN. Goshajinkigan, a Japanese traditional herbal medicine (Kampo), is a promising drug which is used to treat diabetic neuropathy in Japan...

A novel, simple and reliable method based on micellar electrokinetic chromatography with ultraviolet detection was developed to analyze idebenone in a pediatric formulation. Idebenone is a synthetic short chain benzoquinone that acts as an electron carrier in the mitochondrial electron transport chain facilitating the production of adenosine triphosphate. It can be found in two different redox states that differ in their physiological properties. Idebenone has been investigated as a treatment in several neurological disorders like Friedreich's ataxia, Leber's hereditary optic neuropathy, mitochondrial encephalomyopathies and senile dementia...

PURPOSE: The aim of the present study is to investigate the protective effects of oxytocin (OT) on diabetic neuropathy (DNP) in rats. MATERIALS AND METHODS: Eighteen rats were used to induce diabetes using single dose streptozotocin (STZ, 60 mg/kg). Diabetic DNP was verified by electromyography (EMG) and motor function test on 21st day following STZ injection. Six rats served as naïve control group and received no drug (n = 6). Following EMG, diabetic rats were randomly divided into three groups and administered with either 1 ml/kg saline or 80 μg/kg OT or 160 μg/kg OT intraperitoneally for four weeks...

Patients with bilateral vestibular failure (BVF) exhibit imbalance when standing and walking that is linked to a higher fall risk. The purpose of this study was to identify risk factors for falls in BVF. We therefore systematically investigated the interrelationship of clinical and demographic characteristics, gait impairments, and the fall frequency of these patients. Clinical and demographic characteristics as well as quantitative measures of gait performance on a pressure-sensitive gait carpet were collected from 55 patients with different etiologies of BVF...

Glaucoma is an optic neuropathy and a major cause of blindness globally. Trabecular meshwork cells are important in maintaining aqueous humor flow, the dysfunction of which tends to induce glaucoma. As important regulators of gene expression, microRNAs may be crucial in regulating trabecular meshwork cells. The present study aimed to reveal the effect of microRNA‑93 (miR‑93) on glaucoma trabecular meshwork (GTM) cell apoptosis. The expression levels of miR‑93 were compared between human trabecular meshwork (HTM) cells and GTM cells...

INTRODUCTION: Ulnar neuropathy at the elbow (UNE) is a common peripheral compression neuropathy and in most cases occurs at 2 sites, the retroepicondylar groove or the cubital tunnel. With regard to a potential therapeutic approach with perineural corticosteroid injection the aim of this study was to evaluate the distribution of injection fluid applied at a standard site. METHODS: We performed ultrasound-guided (US-guided) perineural injections to the ulnar nerve halfway between the olecranon and the medial epicondyle in 21 upper limbs from 11 non-embalmed cadavers...

Several studies have demonstrated the therapeutic potential of applying microtubule- (MT-) stabilizing agents (MSAs) that cross the blood-brain barrier to promote axon regeneration and prevent axonal dystrophy in rodent models of spinal cord injury and neurodegenerative diseases. Paradoxically, administration of MSAs, which have been widely prescribed to treat malignancies, is well known to cause debilitating peripheral neuropathy and axon degeneration. Despite the growing interest of applying MSAs to treat the injured or degenerating central nervous system (CNS), consequences of MSA exposure to neurons in the central and peripheral nervous system (PNS) have not been thoroughly investigated...

Sensory neuropathies are the most common neurological complication of HIV. Of these, distal sensory polyneuropathy (DSP) is directly caused by HIV infection and characterized by length-dependent axonal degeneration of dorsal root ganglion (DRG) neurons. Mechanisms for axonal degeneration in DSP remain unclear, but recent experiments revealed that the HIV glycoprotein gp120 is internalized and localized within axons of DRG neurons. Based on these findings, we investigated whether intra-axonal gp120 might impair fast axonal transport (FAT), a cellular process critical for appropriate maintenance of the axonal compartment...

BACKGROUND Eosinophilic granulomatosis with polyangiitis (EGPA), also known as Churg-Strauss syndrome (CSS), is a rare vasculitis of unknown etiology. Most of the patients have a long history of asthma and then develop autoimmune inflammation of small and medium-sized blood vessels, with consequent reduction of blood flow to various organs and tissues. EGPA can cause disorders in multiple systems; the most seriously affected organs are the retina, kidney, brain, cardiovascular system, and skin. CASE REPORT The patient was hospitalized for high fever and skin rashes and then developed right upper abdominal pain, decreased visual acuity, coma, and convulsions...
