Collagen protein-chitosan nerve conduits with neuroepithelial stem cells promote peripheral nerve regeneration.

The peripheral nervous system consists of ganglia, nerve trunks, plexuses, and nerve endings, that transmit afferent and efferent information. Regeneration after a peripheral nerve damage is sluggish and imperfect. Peripheral nerve injury frequently causes partial or complete loss of motor and sensory function, physical impairment, and neuropathic pain, all of which have a negative impact on patients' quality of life.

Erythropoietin Protects Erythrocytes Against Oxidative Stress-Induced Eryptosis In Vitro.

Background: Excessive eryptosis has been found in maintained hemodialysis or peritoneal dialysis patients. Signaling of triggering eryptosis includes oxidative stress, increased cytosolic Ca2+-activity, and ceramide. Erythropoietin (EPO) possesses the property of an antioxidant.
