Chemical Reaction Keeps Stroke Damaged Brain from Repairing itself

When the brain produces too much nitric oxide, it contributes to the severity and progression of stroke and neurodegenerative diseases such as Alzheimer’s. Researchers recently discovered that nitric oxide not only damages neurons, it also shuts down the brain’s repair mechanisms.

Stroke Damage in Mice Overcome by Training Which ‘Rewires’ Brain Centers

A new study discovers mice can recover from physically debilitating strokes that damage the primary motor cortex, if the rodents are quickly subjected to physical conditioning that rapidly “rewires” a different part of the brain to take over lost function.

Simulations Show how Blood Vessels Regroup after Stroke

By simulating patterns of microvasculature cell growth and compare the results with real networks grown in lab, researchers hope to direct how they grow into the tiny blood vessels that feed the brain and help people regain functions lost to stroke and disease.

Researchers Uncover New Findings on Genetic Risks of Behçet’s Disease

Researchers identify regions of genes linked to Behçet’s disease, a poorly understood condition that causes painful and serious symptoms, including ulcers and brain inflammation. The study identified novel gene variants in the inflammatory disorder and uncovered data that could apply to studies of other diseases.
