High-resolution real-time images show how nerves may be damaged during earliest stages of MS

High-resolution real-time images show in mice how nerves may be damaged during the earliest stages of multiple sclerosis. The results suggest that the critical step happens when fibrinogen, a blood-clotting protein, leaks into the central nervous system and activates immune cells called microglia.

Topically applied simvastatin enhances wound recovery in diabetic mice

Delayed wound healing is a major complication of diabetes because the physiological changes in tissues and cells impair the wound healing process. This can result in additional disease outcomes such as diabetic foot ulcer, a significant cause of morbidity in the growing population of diabetic patients. A new study has found that topically applied simvastatin accelerates wound healing in diabetic mice, suggesting important implications for humans with diabetes.
