Exercise can shift the human body clock, with the direction and amount of this effect depending on the time of day or night in which people exercise. That's according to new research in published in The Journal of Physiology. These findings suggest exercise could counter the effects of jet lag, shift work, and other disruptions to the body's internal clock (e.g., military deployments) helping individuals adjust to shifted schedules.
The disease systemic lupus erythematosus (SLE) -- marked by the attack on joints, skin, and kidneys by the body's immune system -- is linked to an abnormal mix of bacteria in the gut. This is according to a new study led by scientists at NYU School of Medicine.
Children living in homes with all vinyl flooring or flame-retardant chemicals in the sofa have significantly higher concentrations of potentially harmful semi-volatile organic compounds (SVOCs) in their blood or urine than children from homes where these materials are not present, according to new Duke University-led research. The researchers presented their findings Feb. 17 at the annual meeting of the American Association for the Advancement of Science in Washington, D.C.
Proper development of the fetal penis requires not just testosterone from the testes, but a second hormone produced by other tissues, including the placenta, according to a new study publishing Feb. 14 in the open-access journal PLOS Biology from Paul Fowler of the University of Aberdeen, Michelle Bellingham of the University of Glasgow, and colleagues in the UK, France and Sweden. The results reveal a previously unknown pathway of masculinization of the external genitals.
All women exposed to high levels of DDT are at increased risk for breast cancer through age 54, but the timing of cancer risk depends on when they were first exposed. Women exposed before 14 years of age, particularly in infancy and early childhood, were most likely to develop premenopausal breast cancer, while those who were exposed after infancy were at increased risk of developing cancer later, at 50-54 years of age.
Biology textbooks teach us that adult cell types remain fixed in the identity they have acquired upon differentiation. By inducing non-insulin-producing human pancreatic cells to modify their function to produce insulin in a sustainable way, researchers at the University of Geneva, Switzerland, show for the first time that the adaptive capacity of our cells is much greater than previously thought. Moreover, this plasticity would not be exclusive to human pancreatic cells.
Oral complications are rare in women taking medications for postmenopausal osteoporosis, according to a study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
All women exposed to high levels of DDT are at increased risk for breast cancer through age 54, but the timing of cancer risk depends on when they were first exposed, according to a new study published today in the Journal of the National Cancer Institute by the Public Health Institute's Child Health and Development Studies.
In the largest study to date on phthalates and postmenopausal breast cancer, a University of Massachusetts Amherst cancer epidemiology researcher found no association between breast cancer risk and exposure to the plasticizing and solvent chemicals used in such common products as shampoo, makeup, vinyl flooring, toys, medical devices and car interiors.
A University of Virginia School of Medicine researcher will provide updates on a UVA-developed artificial pancreas -- including early results from a nationwide clinical trial -- during a presentation at the AAAS Annual Meeting. The presentation from Boris Kovatchev, PhD, director of the UVA Center for Diabetes Technology, is scheduled for 1:30-2 p.m. Feb. 15.
