Brain Tumor :: Brain tumors may originate with neural stem cells

Researchers at University of Texas (UT) Southwestern Medical Center have determined that stem cells in a certain region of the brain may be the source of a particular type of incurable brain tumor and may be implicated in other types of brain cancers as well.

Stem Cells :: Discarded placentas deliver researchers promising cells

Routinely discarded as medical waste, placental tissue could feasibly provide an abundant source of cells that may have the potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells, suggests a University of Pittsburgh study to be published in the journal Stem Cells and available now as an early online publication in Stem Cells Express.

Hair Transplant :: Follicular grouping – innovative hair transplant technique

Experiments performed by the hair transplant surgeon Dr Seager in 1996 gave significant credence to the surgical technique of unit follicular hair transplant. Since these experiments had demonstrated that the survival rate of intact follicular unit was better than the single hair micro-grafts, the use of micro-grafts for hair transplant surgery was more or less dropped.

Cholesterol :: Role of cholesterol in atheromatous disease

In conditions with elevated concentrations of LDL particles, especially small LDL particles, cholesterol promotes atheroma plaque deposits in the walls of arteries, a condition known as atherosclerosis, which is a major contributor to coronary heart disease and other forms of cardiovascular disease.
