Researchers test new therapy for advanced melanoma

.... This indicates the immune system formed a memory response that recognized the melanoma cells as foreign and prevented tumor regrowth. "We were very encouraged by the results of the preclinical studies." Dr. Heller said. "We're hoping this translates into a beneficial treatment for patients." The Phase 1 c...

Innovative coating could give medical implants a longer life

Lipids get new comprehensive classification system

In response to the growing number of lipids expected to be discovered through lipidomics and in anticipation of the massive amounts of data that will be generated by the lipid community, an international group of scientists has developed a comprehensive classifi...

Second messenger NAADP shows fast, dose-related impact on satiety cycle

...direct demonstration of changes in NAADP levels in response to agonist-stimulations has been lacking, Yamasaki said. "We found that application of cholecystokinin to isolated populations of pancreatic acinar cells caused NAAPD level to increase as much as 6-fold in only 5 to 10 seconds," Yamasaki said. The c...
