Experts prove the geochemical origin of part of the CO2 emissions in semiarid climates

Experts prove the geochemical origin of part of the CO2 emissions in semiarid climates

The implementation of the Kyoto Protocol has raised, among other pressing matters, the need of getting to know the annual levels of carbon in different earth’s ecosystems. Scientists connected with the CEAMA-Andalusian Centre for the Environment (University of Granada-Andalusian Council) are studying these levels in semiarid Mediterranean scrubland, situated in Eastern Andalusia, whose results are comparable to wide regions of the world.

Folate scores a win in animal studies: Brief, high doses of B vitamin blunt damage from heart attack

Long known for its role in preventing anemia in expectant mothers and spinal birth defects in newborns, the B vitamin folate, found in leafy green vegetables, beans and nuts has now been shown to blunt the damaging effects of heart attack when given in short-term, high doses to test animals.

Long-term use of mechanical ventilation contributes to the deterioration of human diaphragm muscle

PHILADELPHIA – A new study by University of Pennsylvania School of Medicine shows, for the first time in humans, that ventilators combined with diaphragm disuse contributes to muscle atrophy in the diaphragm in as little as eighteen hours. Muscle atrophy in the diaphragm is a major contributor of why patients who have undergone prolonged mechanical ventilation often have difficulty breathing after being removed from the ventilator.

Coronary calcium testing predicts future heart ailments

Irvine, Calif. - Calcium deposits in coronary arteries provide a strong predictor for possible future heart attacks and cardiac diseases, and detecting such deposits can be valuable for promoting overall cardiac health, according to a study led by the University of California, Irvine and appearing in the March 28 issue of the New England Journal of Medicine.

FDA deadlines may compromise drug safety by rushing approval

Many medications are approved by the U.S. Food and Drug Administration on the brink of congressionally mandated deadlines, and those drugs are more likely to face later regulatory intervention than those approved with greater deliberation, researchers at Harvard University have found.

Drugs fast-tracked by the FDA are more likely to eventually be withdrawn from global markets for safety reasons, undergo manufacturing revisions, or face labeling changes, according to Daniel Carpenter, professor of government in Harvard’s Faculty of Arts and Sciences.

Increasing access to antiretroviral drugs would drastically cut AIDS deaths in South Africa

More that 1.2 million deaths could be prevented in South Africa over the next five years by accelerating efforts to provide access to antiretroviral therapy (ART), according to a study released online today by the Journal of Infectious Diseases. Using a sophisticated mathematical model of HIV disease and treatment, a team of researchers led by Rochelle Walensky, MD, MPH of Massachusetts General Hospital (MGH) estimated the number of AIDS-related deaths in South Africa through 2012 under alternative ART scale-up assumptions.
