Two genes linked to binge drinking

University of Maryland School of Medicine researchers have identified two genes associated with binge drinking that may open doors to new, more effective treatments for excessive alcohol drinking. The scientists found that manipulating two receptors in the brain, GABA receptors and toll-like receptor 4 (TLR4), "caused profound reduction" of binge drinking for two weeks in rodents that had been bred and trained to drink excessively. The study was published online the week of Feb. 28 in the journal the Proceedings of the National Academy of Sciences.

Treat discomfort not fever say the new pediatric guidelines

According to a new report from the American Academy of Pediatrics (AAP), fevers alone are not a cause for intervention in children. Dr. Janice Sullivan, the lead author of the report says, “The focus should be on comfort and not on absolute temperature.” That’s because fever can be help fight illness, by slowing down the reproduction of bacteria and viruses or stimulating the body’s immune response she explains. “That’s a benefit of fever…and may shorten the time that your child remains ill,” she adds.

Mouse model could help develop new classes of antidepressant drugs

The most widely prescribed antidepressants - medicines such as Prozac, Lexapro and Paxil - work by blocking the serotonin transporter, a brain protein that normally clears away the mood-regulating chemical serotonin. Or so the current thinking goes.

Slime of starfish may hold a clue for treating inflammatory diseases

Starfish have arms, spines and a mouth on the underside of its body. But what scientists are finding really interesting is the sticky goo which is secreted when the Starfish feels threatened. The slime contains properties which may prove invaluable in treating certain kinds of inflammatory illnesses.

Crustacean inspired technology leads to better calcium supplements

Ben-Gurion University of the Negev (BGU) researchers have developed a unique technology that stabilizes an otherwise unstable form of calcium carbonate. This mineral form provides significantly higher biological absorption and retention rates than other sources presently used as dietary calcium supplements.

Study explores role of proline containing peptides in inhibiting anti-apoptotic function of XIAP

Basic and translational research on cancer, and development of new cancer therapeutics, has focused on different aspects of cancer cellular function. One area of focus is the life and death of a cancer cell. Apoptosis, also known as programmed cell death, is a fundamental process of cells including cancer cells. The signal transduction pathways of apoptosis involve many different proteins and their interactions with each other.
