Bone Density Recovers After Teens Stop Injected Contraceptive

...t used DMPA had used other forms of contraception, including oral contraceptives. Oral contraceptives also contain hormones. Some contain a combination of the hormones estrogen and progestin, some contain only progestin. It is not known whether oral contraceptive use affects bone mineral density and NICHD is c...

Breast-Cancer Risk Linked to Exposure to Traffic Emissions at Menarche, First Birth

...e years from 1960 to 2002 and tail-pipe emissions, including measurements from tunnels and tests on individual vehicles. A geographic model was used to reconstruct historic traffic PAHs, using measurements of benzo[a]pyrene, a known potent mutagen and carcinogen, as a surrogate for total PAH exposure. Cruise e...

New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

...ific autoantibodies that react with many proteins, including one's own tissues, like the antibodies made by innate B cells. In laboratory tests, the antibodies reacted with multiple types of human molecules, most prominently with a fat molecule called cardiolipin. "It appears the most vulnerable spots on the ...

Researchers develop rapid diagnostic tool for pathogen identification

... assay that detects and discriminates 22 pathogens including viruses and bacteria that can present as clinically similar pulmonary disease. This new technology platform addresses important challenges for infectious disease identification—sensitivity and breadth. Mass Tag PCR provides the ability to be precis...

Genetically modified rice in China benefits farmers' health, study finds

The study found that cryptorchidism was associated with low birth weight, preterm delivery, small gestational weight and other congenital abnormalitie...

Variation in women's X chromosomes may explain differences among individuals, between sexes

...he same issue of Nature, more than 250 researchers including Willard and Carrel, reported the complete DNA sequence of the human X chromosome. In animals, sexual identity is governed by sex chromosomes. In humans and other mammals, males have one X and one Y chromosome, while females have a pair of X's. Many...

Drug-resistant bacteria on poultry products differ by brand

The widespread presence of this drug-resistant form of the bacteria makes the antibiotic less effective in human medicine. Especially vulnerable are the very young, the elderly and people whose immune systems are compro...

Hirsute Or Hairless? Two Proteins May Spell The Difference
