Gel provides protection from HIV and herpes

Mount Sinai School of Medicine researchers demonstrated that a gel applied in the vagina provides protection from both the human immunodeficiency virus (HIV) and the herpes simplex Virus. The study, presented at the 12th Conference on Retroviruses and Opportunistic Infections, is the first to show that a gel can retain anti-viral activity within the human vagina.

Common epigenetic problem doubles cancer risk

In experiments with mice, a team of scientists from the United States, Sweden and Japan has discovered that having a double dose of one protein is sufficient to change the normal balance of cells within the lining of the colon, thereby doubling the risk that a cancer-causing genetic mutation will trigger a tumor there.

Cellular porthole has a major role in helping the brain sense odors

A cellular "porthole" known best for its role in the digestive system apparently has a major role in helping the brain sense odors, Johns Hopkins scientists report in the Feb. 17 issue of Neuron. The porthole, which lets chloride into cells, is also critical in digestion, hearing, balance, and fertility.

Protein called CK2 plays a deadly role in colorectal carcinoma

A protein called CK2 plays a deadly role in colorectal carcinoma by blocking the ability of these tumors to activate a natural self-destruct mechanism that would clear this cancer from the body. This finding, by researchers at St. Jude Children's Research Hospital, is currently published in the online edition of Oncogene.

Mathematical model describes the electrical storm that rages during a brain seizure

"We're trying to get to the underlying state of the brain that leads to these seizures," said Mark Kramer, a Ph.D. student in UC Berkeley's Applied Science and Technology Program and lead author of the paper. "Our hope is that the model can highlight potential areas where a seizure can be stopped."

Is it exercise or dieting that helps prevent cancer?

Scientists and health professionals have long believed that maintaining a healthy - or "ideal" - weight makes a difference in decreasing an individual's risk for cancer. But one lingering question is whether or not it's better, in terms of cancer prevention, if that weight is reached and maintained by dieting or by exercising.
