Why do African-American women have more pregnancy problems?
... women has improved in recent years, it still lags behind white women: 75 percent of black women seek prenatal care vs. 89 percent of white women. The discrepancy continues after the baby is born too: 58 percent of white infants get all recommended well-child care, compared to 35 percent of black infants. F......ex. Both are located toward the front of the brain behind the forehead. Previously, brain scan studies have found differences in brain activity levels and size in these areas in people with psychiatric illnesses. In the current paper, the researchers report what they found when they zeroed in on a group of ...OHSU study: Bacterial switching mechanism key to survival
..., OHSU School of Medicine, uncovered the mechanism behind the ability of "gram-positive" bacteria to switch their metabolic programs to take advantage of the best-available carbon source for energy. Gram-positive bacteria include those that cause staph infections, strep throat, pneumonias, botulism, toxic s...ENCODE consortium publishes scientific strategy

This finding has implications for understanding how congenital heart defects occur, and may lead to genetic tests for certain defects, such as proteins that determine how genes are expressed. This also opens new insights int...Link between immune protein and longer survival in melanoma patients identified
