CHICAGO (Reuters) - Breastfeeding, backed for the health effects it bestows on the baby, also appears to reduce the mother's risk of developing adult onset diabetes, researchers said on Tuesday.

NEW YORK (Reuters Health) - The presence of a specific gene mutation and low birth weight appear to increase the risk of early-onset antisocial behavior in children with attention-deficit/hyperactivity disorder, according to findings published in the Archives of General Psychiatry. Dr.

In the neural train wreck that is stroke, the cutoff of oxygen kills brain cells through a buildup of acid, as well as by overexciting receptors on the surface of brain cells. Now, researchers exploring the detailed mechanism of this excitotoxicity and acidotoxicity have discovered how an insidious chain of molecular events contributes to its damage. In an article in the November 23, 2005, issue of Neuron, Jun Gao and colleagues say that their findings could contribute to the development of drugs to protect against the molecular "cabal" that produces such lethality.

CHICAGO (Reuters) - The blood-thinning drug Lovenox works as well as a standard artery-clearing drug in patients with severe heart-related chest pain, but neither reduced the risk of death after a year of treatment, a study said on Tuesday.

Neonatal mortality rates--that is, mortality in the first 28 days--in the United States fell significantly between 1940 and 2000 from 28.8 deaths per live birth to 4.6 deaths. Yet ethnic and racial disparities have persisted or increased during that time. Deaths among very low-birthweight infants (VLBW) account for more than half the infant deaths in the United States. The researchers sought to determine whether there is a correlation between mortality among VLBW infants and quality of care. The research was based on data from 74,000 infants at 332 hospitals across the nation.

In investigating the molecular mechanisms of cancer cell motility – the unique property that enables cancer to spread from its primary origin to other parts of the body – researchers have uncovered a surprising role for the AKT/PKB (protein kinase B) enzyme, providing important new insights into cancer metastasis and suggesting that current efforts to develop cancer therapies by inhibiting AKT may be inadvertently promoting the spread of the disease.

A University of Minnesota Cancer Center study indicates that older women who receive radiation therapy for treatment of pelvic cancers have an increased risk of hip and other pelvic fractures later in life. Researchers encourage such women to talk with their physicians about their risks and preventive measures, including having their bone density levels checked.

By Graciela Flores NEW YORK (Reuters Health) - Women who breastfeed longer have a lower risk of developing type 2 diabetes, new research shows.

NEW YORK (Reuters Health) - Women who have recently had diabetes develop during pregnancy, a condition known as gestational diabetes, are often insufficiently physically active after giving birth.

Previous studies have suggested that people reduce their average alcohol consumption as they age. In the new study the researchers sought to determine whether the percentage of heavy drinkers--that is, men who have at least five drinks in one sitting and women who have at least four drinks -- also reduced as they aged. This latest study was based on data from 14,127 participants, aged 25 to 74, in the National Health and Nutrition Examination Study, first administered between 1971 and 1974, with three follow-ups through 1992.
