GAINESVILLE, Fla. — Blueberry wine can provide more potentially healthy compounds than white wines and many red wines, according to a new University of Florida study.

Researchers with UF’s Institute of Food and Agricultural Sciences measured antioxidant content in a Florida-produced blueberry wine and compared it to published reports of antioxidant content in white and red wines made from grapes. Antioxidants are compounds that may offer cells protection from damaging molecules called free radicals. (more…)

Chemists Unlock Potential Target For Drug Development

EAST LANSING, Mich. — A receptor found on blood platelets whose importance as a potential pharmaceutical target has long been questioned may in fact be fruitful in drug testing, according to new research from Michigan State University chemists.

A team led by Dana Spence of MSU’s Department of Chemistry has revealed a way to isolate and test the receptor known as P2X1. By creating a new, simple method to study it after blood is drawn, the team has unlocked a potential new drug target for many diseases that impact red blood cells, such as diabetes, hypertension and cystic fibrosis.

*Research could lead to techniques to improve fertilization in humans*

In new research that could have implications for improving fertilization in humans and other mammals, life scientists studied interactions between individual sperm and eggs in red abalone, an ocean-dwelling snail, and made precise chemical measurements and physical models of these interactions. They are the first scientists to do so.

By simulating the natural habitat of the abalone in the laboratory, the scientists were able to determine the conditions under which sperm–egg encounters and fertilization were most likely to occur. (more…)

Scientists Now Know Why Some Cancers Become Malignant and Others Don’t

Cancer cells reproduce by dividing in two, but a molecule known as PML limits how many times this can happen, according to researchers lead by Dr. Gerardo Ferbeyre of the University of Montreal’s Department of Biochemistry. The team proved that malignant cancers have problems with this molecule, meaning that in its absence they can continue to grow and eventually spread to other organs. Importantly, the presence of PML molecules can easily be detected, and could serve to diagnose whether a tumor is malignant or not. (more…)
