We have investigated the properties of nerve cell precursors in hydra by analyzing the differentiation and proliferation capacity of interstitial cells in the peduncle of Hydra oligactis, which is a region of active nerve cell differentiation. Our results indicate that about 50% of the interstitial cells in the peduncle can grow rapidly and also give rise to nematocyte precursors when transplan...

In hydra, HA is produced by nerve cells and released into the intercellular space bound to large-molecular-weight carrier(s). By additional interaction with extracellular matrix components and selfinactivation by dimerisation, a local action is ensured. HA acts as a mitogen on all dividing cell types in hydra forcing them to pass through G2, divide, and either start a new round of cell division...

We aim to understand the role of immunity microbiota and IL17 in nerve overgrowth display psoriasis skin. used a model pre-exposure imiquimod (IMQ) induce skin inflammation mice. Skin sensory neurons participate physiology immunity. released by commensal-specific Th17 directly signals via IL17RA promotes regeneration upon injury. Neurogenic is essential psoriasis. Psoriasis patients report neur...

traffic accident has increased in the last decade. one of the most important outcomes of accident is spinal cord injury (sci). so, cell therapy is obtained a greater attention in most fields of medicine because of its potential for incurable diseases through replacing of dead cells. the current study aims to describe the important of locomotor functional and structural connection of the spinal ...

Controlling nerve cells to form pre-designed 3D neural networks that recapitulate the intricate interconnectivity in brain is essential for developing neuronal interfaces and new regeneration approaches. Here, within biomaterials are dynamically localized using nano-based magnetic manipulations. Nerve transformed into units their organizational layout manipulated external field gradients. Iron ...

Studies, which evaluated the effects of 632.8nm and 780nm laser irradiation on Schwann 1 and nerve cell 2 cultures and injured peripheral nerves of animals 3-7 showed positive results. Laser phototherapy induces Schwann cell proliferation 1 and affects nerve cell metabolism and induces nerve processes sprouting 2. Laser phototherapy significantly improves recovery of the injured peripheral nerv...

Oculomotor palsy is one of the most frequent neuro-ophthalmologic complications in patients with diabetes. Specifically, sixth nerve common. A 51-year-old female a past medical history type 1 diabetes on insulin and hypertension presented complaints worsening headache diplopia. Physical exam was remarkable for recurrent palsy. Patient hemodynamically stable. Labs showed blood glucose 367 mg/dL ...

Apoptotic nerve cell death is implicated in the pathogenesis of several devastating neurodegenerative conditions, including glaucoma and Alzheimer's and Parkinson's diseases. We have devised a noninvasive real-time imaging technique using confocal laser-scanning ophthalmoscopy to visualize single nerve cell apoptosis in vivo, which allows longitudinal study of disease processes that has not pre...

gonadotropin-releasing hormone (gnrh) has neuromodulatory roles in central and peripheral nervous systems. the purpose of this study is to evaluate the effect of gnrh analog (buserelin) on peripheral nerve regeneration. forty adult male rats were divided into buserelin-treated, normal saline, sham surgery, and castrated + buserelin groups. the left sciatic nerve was crushed by a fine forceps an...

case presentation in this report, ultrasound-guided sciatic nerve block was performed in a 25-year-old patient with tetanus to progress his respiratory drive which was decreased due to high dose sedative administration. this procedure accelerates the weaning process and extubation. introduction muscle rigidity and generalized spasm can cause severe pain in patients with tetanus. administration ...
