Cellular metabolism arms T cells to battle viruses and tumors Posted: 24 Dec 2012 08:34 AM PST New research demonstrates that the cellular metabolism of certain immune cells is closely linked to their function, which includes protecting against viral infections and the development of tumors. Results recently published reveal the relationship between glucose metabolism in Cytotoxic T lymphocytes (CTL) and their ability to acquire the tools necessary to migrate and kill virally infected cells or tumor cells.

How excess holiday eating disturbs your 'food clock' Posted: 24 Dec 2012 08:33 AM PST If the sinful excess of holiday eating sends your system into butter-slathered, brandy-soaked overload, you are not alone: People who are jet-lagged, people who work graveyard shifts and plain-old late-night snackers know just how you feel. All these activities upset the body's "food clock," a collection of interacting genes and molecules known technically as the food-entrainable oscillator, which keeps the human body on a metabolic even keel. A new study is helping to reveal how this clock works on a molecular level.

Ultrasound diagnoses appendicitis without X-rays Posted: 24 Dec 2012 08:33 AM PST Children suspected of having appendicitis are more likely to receive CT scans, which involve radiation, if they are evaluated at a general hospital, a new study has shown.

Nearly one in three children with food allergies experience bullying, survey shows Posted: 24 Dec 2012 08:33 AM PST Nearly a third of children diagnosed with food allergies who participated in a recent study are bullied, according to researchers. Almost eight percent of children in the U.S. are allergic to foods such as peanuts, tree-nuts, milk, eggs, and shellfish.

Gene variants affect pain susceptibility in children Posted: 24 Dec 2012 08:33 AM PST At least two common gene variants are linked to "clinically meaningful" differences in pain scores in children after major surgery, a new study reports.

How shrubs are reducing the positive contribution of peatlands to climate Posted: 23 Dec 2012 03:00 PM PST Peatlands (bogs, turf moors) are among the most important ecosystems worldwide for the storage of atmospheric carbon and thus for containing the climate warming process. In the last 30 to 50 years the peat (Sphagnum) mosses, whose decay produces the peat (turf), have come under pressure by vascular plants, mostly small shrubs.
