Background: Postherpetic neuralgia (PHN) is persistent pain in the affected dermatome that occurs more than three months after eruption of herpes zoster has disappeared. Vitamin D a role Schwann cell regeneration and stimulates release nerve growth factors.

One of the most nervous system evolution are memory and learning in humans. Learning is a skill that enhances synaptic activity in the hippocampus of prefrontal cortex. In fact, basic passive learning is communication between the conditioned and Unconditioned stimulation. Passive learning involves three steps: habit, education and remember. According to the results of investigations, the hippoc...

the p75 pan-neurotrophin receptor (p75ntr) plays a pivotal role in linking the immune system with the nervous system. p75ntr is required for the development of several characteristic features of allergic asthma. also p75ntr upregulated by reactive schwann cells after peripheral nerve injury. moreover p75ntr and rhoa play a critical role in the regulation of apoptosis. to determine whether the d...

Background: Pigment epithelium-derived factor (PEDF) is regarded as a multifunctional protein possessing neurotrophic and neuroprotective properties. PEDF has a very short half-life, and it would require multiple injections to maintain a therapeutically relevant level without a delivery system. However, multiple injections are prone to cause local damage or infection. To overcome this, we chose...

background: two main muscles studied in the hand for evaluation of median nerve injuries are opponens pollicis (op) and abductor pollicis brevis (apb). however, riché-cannieu communicating branch (rccb) may limit the use of these muscles in electrodiagnosis. this condition is confusing in the case of median nerve injuries. this study was conducted to evaluate the prevalence of rccb.   methods: ...

conclusions our results support the use of pns in some patients with refractory chronic headaches. appropriate surgical planning and technique are important to achieve good clinical outcome and to minimize complications. background subcutaneous peripheral nerve stimulation (pns) has emerged as a useful tool in the treatment of intractable headaches. however, complications such as skin erosion, ...

The nerve injury, whether it results in tissue loss or not, involves cutting off the nerve, making impossible for two portions to interact and, as a result, impairing functionality. Mesenchymal stem cells are one of best options cell therapy many diseases due their distinct functional properties, such potent differentiation capacity, immunomodulatory capacity and growth support. secretome gener...
