Doctors issue stern warning on e-cigarette use as it can damage vital organs

E-cigarette use has increased dramatically over the last decade. With its popularity, the use of e-cigarette spans from adolescents to adults. Now, cardiologists warn against the use of e-cigarettes and how these devices cause damage to vital organs, including the heart, brain, lungs, and blood vessels.

Study describes a molecular strategy that helps prevent development of tumors in mice

The body's process for manufacturing fatty acids is regulated by the enzyme FASN. In normal cells, this is not a very active process - except occasionally in the liver and adipose tissue - since most of the fatty acids we need for cell maintenance are obtained from the diet.

Stony Brook-led study reveals how proteome collapse process drives cell death and aging

Cells undergo natural aging and death, processes that impact a multitude of cellular factors. A new Stony Brook University-led study, to be published in PNAS, provides a biophysical model that reveals how damage accumulates in the shapes of cellular proteins with age and is a trigger to death.

Study shows microRNA can protect the heart from reperfusion injury

Heart muscle can continue to die even after restoring blood following a heart attack, and scientists have new evidence that one way to help it live is by boosting levels of a tiny RNA that helped the heart form.
