Human adult testes cells can become embryonic-like

Using what they say is a relatively simple method, scientists at Georgetown University Medical Center have extracted stem/progenitor cells from testes and have converted them back into pluripotent embryonic-like stem cells.

Thinning of right hemisphere in brain a marker for familial form of depression

Findings from one of the largest-ever imaging studies of depression indicate that a structural difference in the brain - a thinning of the right hemisphere - appears to be linked to a higher risk for depression, according to new research at Columbia University Medical Center and the New York State Psychiatric Institute.

Levels of PLTP enzyme in blood should be a consideration for potential statin treatment

In a patient study of over 1,000 individuals with coronary artery disease (CAD), researchers have found that high levels of an enzyme called PLTP significantly increased the risk of heart attack in the subset of patients taking statins.
