New pain mechanisms revealed for neurotoxin in spinal cord injury

A toxin released by the body in response to spinal cord injuries increases pain by causing a proliferation of channels containing pain sensors, new research shows, and this hypersensitivity also extends to peripheral nerves ...

Dental pulp cell transplants help regenerate peripheral nerves

Peripheral nerve injuries often are caused by trauma or surgical complications and can result in considerable disabilities. Regeneration of peripheral nerves can be accomplished effectively using autologous (self-donated) ...

Older people may have glaucoma without realizing it

It can be hard to know that you have glaucoma. In a study carried out at the University of Gothenburg, almost 5% of 70-year-olds were found to have glaucoma, and half of those diagnosed were unaware that they had the disease.

Zebrafish reveal how axons regenerate on a proper path

When peripheral nerves are damaged and their vital synaptic paths are disrupted, they have the ability to regenerate and reestablish lost connections. But what about when a nerve is severed completely, its original route ...

New molecular mechanism of neuropathic pain in mice

A research group from Hiroshima University demonstrated that the downregulation of spinal astrocyte connexin43 (Cx43) expression causes sustained neuropathic pain following peripheral nerve injury. Controlling the Cx43 expression ...

Hybrid tunnel may help guide severed nerves back to health

Building a tunnel made up of both hard and soft materials to guide the reconnection of severed nerve endings may be the first step toward helping patients who have suffered extensive nerve trauma regain feeling and movement, ...

Recovery protocol cuts opioid use after elective neurosurgery

(HealthDay)—Enhanced recovery after surgery (ERAS) protocols can reduce postoperative use of opioids in patients undergoing elective spine and peripheral nerve surgical procedures, according to a study published online ...

Unique 3-D images reveal the architecture of nerve fibers

In an international collaboration led by Lund University in Sweden, researchers have used synchrotron light to study what happens to the nerves in diabetes. The technique shows the 3-D structure of nerve fibers in very high ...
