New Treatment for Knee Injuries

MIT engineers have built a new tissue scaffold that can stimulate bone and cartilage growth when transplanted into knees and other joints, potentially offering a more effective, less expensive – and painful – option to more conventional therapies.
The scaffold developed by MIT has two layers, one that mimics bone and another that mimics cartilage. When implanted into a joint, the scaffold can stimulate mesenchymal stem cells in the bone marrow to produce new bone and cartilage.
The researchers demonstrated the scaffold's effectiveness in a 16-week study involving goats. In the study, the scaffold successfully stimulated bone and cartilage growth after being implanted in the goats' knees. Although the technology is still limited to small defects, using scaffolds roughly 8 mm (0.3-inches) in diameter, the scaffold offers a potential new treatment for sports injuries and other cartilage damage, such as arthritis.

Pills Against Insomnia Cause Sleepwalking

Ambien and Lunest are often prescribed sleeping pills. These pills, however, cause the most strange side effects. The Food and Drug Administration reported yesterday such strange behavior as eating or driving while asleep.

These reports have provoked the F.D.E. to order the drug makers to make certain fliers for such sleeping drugs, where patients could read detailed instructions on how to use them.

The investigation of such side effects was caused by, but limited to numerous reports from the users of Ambien (the most prescribed sleeping drug). Their complaints ranged from harmless sleepwalking and hallucinations to eating while asleep, violent outbursts and driving, which is the most disturbing.
