Experimental models for the investigation of nerve regeneration are critical in studying new strategies able to promote the repair process. The aim of the present work was to characterize morphological and functional aspects of sciatic nerve regeneration after mechanical crush injury in rodents. Morphological changes were assessed after a four minutes sciatic nerve injury induced by means of a ...

Diabetes Mellitus, a highly prevalent and rapidly increasing metabolic disease, can cause several serious complications including visual damage blindness caused by ocular nerve damage. Nerve fiber degeneration might occur because of the accumulation glycation end-products in Descemet’s membrane nerve. The severity corneal diabetic keratopathy be examined through regeneration nerves, specificall...

Sural nerve regeneration and sensation were evaluated in 16 subjects five or more years after fascicular or whole nerve biopsy. Conduction studies demonstrated successful nerve regeneration in all subjects who had whole nerve biopsy. Postbiopsy interrogation revealed no long-term pain or paresthesias but a high incidence of tactile-induced dysesthesias. No significant difference was seen when a...

BACKGROUND Photobiomodulation by red to near-infrared light-emitting diodes (LEDs) has been reported to accelerate wound healing, attenuate degeneration of an injured optic nerve, and promote tissue growth. The purpose of this study was to investigate the effect of LEDs on nerve regeneration. A histological study as well as a measurement of antioxidation levels in the nerve regeneration chamber...

Retinal ganglion cells are usually not able to regenerate their axons after optic nerve injury or degenerative disorders, resulting in lifelong visual loss. This situation can be partially reversed by activating the intrinsic growth state of retinal ganglion cells, maintaining their viability, and counteracting inhibitory signals in the extracellular environment. Advances during the past few ye...

Diabetic peripheral neuropathy (DPN) is one of the most common complications of chronic diabetes mellitus. Pathological characteristics of DPN include axonal atrophy, nerve demyelination, and delayed regeneration of peripheral sensory nerve fibers. The goal of treatment in DPN is not only to ameliorate neurological symptoms but also to slow or reverse the underlying neurodegenerative process. S...

Injury to peripheral nerves can occur as a result of various surgical procedures, including oral and maxillofacial surgery. In the case of nerve transaction, the gold standard treatment is the end-to-end reconnection of the two nerve stumps. When it cannot be performed, the actual strategies consist of the positioning of a nerve graft between the two stumps. Guided nerve regeneration using nano...

We assessed the effects of treatment with 4-methylcatechol (4MC), a known inducer of nerve growth factor, on peripheral nerve regeneration by analyzing cutaneous and muscular reinnervation in mice after sciatic nerve crush injury. At 3 months postinjury, the skin innervation index was significantly higher in the 4MC group than the control group (p=0.0002); there was also increased unmyelinated ...

BACKGROUND AND AIM Curcumin at 100mg/kg has been shown to have a protective effect on crush nerve injury. However, it is unclear whether the protective effect of curcumin on nerve injury is dose dependent. The present study was designed to investigate such a possibility. METHODS The rats subjected to crush nerve injury were intraperitoneally administrated daily for 4 weeks with curcumin (50 m...

Design and construction of biocompatible tissue-engineered stents for long segment peripheral nerve regeneration has become a significant research topic. However, in the early of damaged, the immigration and aggregation of inflammatory cells and factors can induce a secondary nerve injury and peroxide damage to the injured nerves, which in turn can result in severe neuronal apoptosis. The use o...
