... and a half weeks into the new nerve growth, Houle implanted a small pump that delivered a steady dose of chondroitinase to a new incision site near C5 where the researchers hoped to reconnect the other end of the bridge to the spinal cord, but also prevent further scarring.

...onal Heart, Lung, and Blood Institute, the authors implanted a mutant human desmoplakin gene into mice, which resulted in the mice's cardiac integrity being compromised, leading to dilation of the right ventricle, buildup of scar and fatty tissue, and arrhythmia.

Then they were exposed to extinction procedures (saline replaced cocaine, and cocaine-associated cues were removed) until lever pressing abated. Reinstatement of drug seeking was triggered by a priming injection of cocaine. AM251 inhibited...Cancer stem cells spur glioma angiogenesis, could hold key to brain tumor therapy
...These stem cell-like glioma cells form tumors when implanted in animals. As the ability to form new blood vessels (called angiogenesis) to supply blood carrying nutrients is critical in cancer growth, Dr. Rich's team studied if the formation of tumors by stem cell-like glioma cells could be due to increased an...News tips from the Journal of Neuroscience
