He also sees applications in medical procedures ?such as artificial skins for surgery. The ideas are in the early stages with health and s...

UCLA/Toronto researchers unlock key to memory storage in brain

...nked the CREB protein to keeping memories stable," added Silva, a member of the UCLA Brain Research Institute. "We suspected it also played a key role in channeling memories to brain cells that are ready to store them." Silva and his colleagues used a mouse model to evaluate their hypothesis. They impl...

The NHPD issues product licenses in several categories. Because COLD-fX® is a unique patented product, it was issued an NPN ...

Statin plus cancer drug deliver combo punch to brain cancer cells

...-survival signal, and lovastatin could provide the added boost necessary to kill more cancer cells." Specifically, Eberhart found links between the expression of key hedgehog-related genes in medulloblastoma cells and another cell signal already tied to cancer, Bcl-2. Eberhart and his team believed that...
