Exposure to phthalates increases risk of asthma-related airway inflammation in children

Children exposed to diethyl phthalate (DEP) and butylbenzyl phthalate (BBzP)-phthalate chemicals commonly found in personal care and plastic products-have elevated risk of asthma-related airway inflammation, according to researchers at Columbia Center for Children's Environmental Health (CCCEH) at the Mailman School of Public Health.

Exposure to perfluorooctanoic acid appears to increase risk of CVD and peripheral arterial disease

Exposure to perfluorooctanoic acid (PFOA), a manmade chemical used in the manufacture of some common household products, appears to be associated with cardiovascular disease and peripheral arterial disease in a study of 1,216 individuals, according to a report published Online First by Archives of Internal Medicine, a JAMA Network publication.

Exposure to polychlorinated biphenyls could increase risk of asthma symptoms in children

Children who are exposed to polychlorinated biphenyls (PCBs), which were commonly used in a range of industrial products, could be at risk of an increase in asthma symptoms, according to new research.

Prenatal exposures to polyfluoroalkyl compounds may lead to obesity in babies

Pregnant women who are highly exposed to common environmental chemicals - polyfluoroalkyl compounds (PFCs) - have babies that are smaller at birth and larger at 20 months of age, according to a study from Emory University's Rollins School of Public Health published online in the August 30 edition of Environmental Health Perspectives.

MAOA gene appears to make women happy

A new study has found a gene that appears to make women happy, but it doesn't work for men. The finding may help explain why women are often happier than men, the research team said.

SPR microscopy examines binding kinetics of membrane proteins

Proteins adorning the surfaces of human cells perform an array of essential functions, including cell signaling, communication and the transport of vital substances into and out of cells. They are critical targets for drug delivery and many proteins are now being identified as disease biomarkers - early warning beacons announcing the pre-symptomatic presence of cancers and other diseases.

Refrigerating coal-plant emissions would reduce levels of dangerous chemicals in air

Refrigerating coal-plant emissions would reduce levels of dangerous chemicals that pour into the air -- including carbon dioxide by more than 90 percent -- at a cost of 25 percent efficiency, according to a simple math-driven formula designed by a team of University of Oregon physicists.

More than 40 plant-based compounds can turn on genes that slow the spread of cancer

More than 40 plant-based compounds can turn on genes that slow the spread of cancer, according to a first-of-its-kind study by a Washington State University researcher.

Study investigates effects of passive smoking on the levels of three parameters

"It is well known that passive smoking is harmful for cardiovascular health, but the mechanism has not yet been discovered," said Dr Kaya. "We investigated the effects of passive smoking on the levels of three parameters - mean platelet volume (MPV), carboxyhemoglobin (COHb) and lactate - in an effort to further understand this mechanism. We also looked at the correlation between the three parameters."

Chemists develop new lab test to examine how DNA damage disrupts protein synthesis

Transcription is a cellular process by which genetic information from DNA is copied to messenger RNA for protein production. But anticancer drugs and environmental chemicals can sometimes interrupt this flow of genetic information by causing modifications in DNA.
