Key aspects of human cell aging reversed by new compounds

Key aspects of the aging of human cells can be reversed by new compounds. In a laboratory study of endothelial cells, researchers tested compounds designed to target mitochondria. The number of senescent cells (older cells that have deteriorated and stopped dividing) was reduced by up to 50 percent.

Solving its insolubility, researchers discover method to deliver curcumin to cancer cells

Scientists have discovered that curcumin to be an effective agent for killing cancer cells. Curcumin’s effective has been extremely limited because it isn’t natually soluble in water. Recently, however a team has created a sophisticated metallocyclic complex using platinum that has not only enabled curcumin’s solubility, but whose synergy has proven 100 times more effective in treating various cancer types such as melanoma and breast cancer cells than using curcumin and platinum agents separately.
