Gene linked to inherited blood biomarker associated with asthma risk

Risk for developing asthma is linked to variants in a gene called CHI3L1, which can be measured by checking levels of an inherited blood protein regulated by that gene, according to new research sponsored by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health.

Researchers close in on origins of main ingredient of Alzheimer's plaques

The ability of brain cells to take in substances from their surface is essential to the production of a key ingredient in Alzheimer's brain plaques, neuroscientists at Washington University School of Medicine in St. Louis have learned.

Repeated methamphetamine use causes long-term adaptations in brains of mice

Repeatedly stimulating the mouse brain with methamphetamine depresses important areas of the brain, and those changes can only be undone by re-introducing the drug, according to research at the University of Washington and other institutions.

Soy appears to protect against development of breast cancer

Evidence is growing from animal and human studies that genistein, a potent chemical found in soy, protects against development of breast cancer - but only if consumed during puberty, says a Georgetown University Medical Center researcher in the British Journal of Cancer published online today.
