Resveratrol shows therapeutic potential for cancer chemoprevention as well as cardioprotection. Resveratrol may aid in the prevention of age-related disorders, such as neurodegenerative diseases, inflammation, diabetes and cardiovascular disease. Low doses of resveratrol improve cell survival as a component of cardio- and neuro-protection, while high doses increase cell death.

Researchers have discovered a reason why smoking increases the risk of heart disease and strokes. Nicotine promotes insulin resistance, also called prediabetes, which is a risk factor for cardiovascular disease.

What was once thought of as DNA with zero value in plants–dubbed “junk” DNA–may turn out to be key in helping scientists improve the control of gene expression in transgenic crops.

Researchers have found that a specific type of immune cell, the regulatory T lymphocyte plays an important role in hypertension-induced cardiac damage. The injected Treg that they harvested from donor mice into recipient mice were infused with angiotensin II, a blood pressure-raising peptide. The Tregs had no influence on the blood pressure response to angiotensin [...]

Cocaine and heroin increase permeability of the placenta. Researchers have shown that exposure to the drugs causes an increase in the passage of some chemicals into the fetus.
