Prenatal BPA exposure associated with diminished lung function in children

Prenatal BPA exposure associated with diminished lung function in children

Date: October 6, 2014 Source: The JAMA Network Journals Summary: Prenatal exposure to bisphenol A, a common chemical used in some plastics, appears to be inconsistently associated with diminished lung function and the development of persistent wheeze in children. Prenatal exposure to bisphenol A (BPA, a common chemical used in some plastics) appears to be inconsistently associated with diminished lung function and the development of persistent wheeze in children, write Adam J Continue reading

Stochastic variations of migration speed between cells in clonal populations

Stochastic variations of migration speed between cells in clonal populations

Microfluidic tools for precision measurements of cell migration speed reveal that migratory speed of individual cells changes stochastically from parent cells to their descendants, while the average speed of the cell population remains constant through successive generations. A team of researchers at the Massachusetts General Hospital and Harvard Medical School in Boston has developed technologies for precision measurement of cell migration speed before and applied the new tool to study the variations of migration speed in population of cancer cells. This tool enabled comparisons between successive generations of cells with single cell resolution. Continue reading

Earlier intervention for common form of heart attack linked to improved survival

Earlier intervention for common form of heart attack linked to improved survival

Changes in the treatment of the most common form of heart attack over the past decade have been associated with higher survival rates for men and women regardless of age, race and ethnicity, according to a UCLA-led analysis. But the study also suggests that there is room for improvement in how current treatment guidelines are applied among specific patient groups. The researchers reviewed records for 6.5 million people who were treated for heart attacks between 2002 and 2011 Continue reading

New discovery in living cell signaling

New discovery in living cell signaling

A breakthrough discovery into how living cells process and respond to chemical information could help advance the development of treatments for a large number of cancers and other cellular disorders that have been resistant to therapy. An international collaboration of researchers, led by scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley, have unlocked the secret behind the activation of the Ras family of proteins, one of the most important components of cellular signaling networks in biology and major drivers of cancers that are among the most difficult to treat Continue reading

Brain may never fully recover from exposure to paint, glue, degreasers

People who are exposed to paint, glue or degreaser fumes at work may experience memory and thinking problems in retirement, decades after their exposure, according to a study published in the May 13, 2014, print issue of Neurology ®, the medical journal of the American Academy of Neurology. “Our findings are particularly important because exposure to solvents is very common, even in industrialized countries like the United States.” said study author Erika L.

Eating fruits, vegetables linked to healthier arteries later in life

Eating fruits, vegetables linked to healthier arteries later in life

Women who ate a diet high in fresh fruits and vegetables as young adults were much less likely to have plaque build-up in their arteries 20 years later compared with those who consumed lower amounts of these foods, according to research to be presented at the American College of Cardiology’s 63rd Annual Scientific Session.

Pollution linked to low birth weight

5 February 2013 Last updated at 20:46 ET Pregnant women who live in areas with significant air pollution risk having babies of low birth weight, the largest study to date suggests. The study, in Environmental Health Perspectives, looked at more than three million births in nine nations. Continue reading

Hospital patient loads often at unsafe levels, physician survey says

Jan. 28, 2013 — Nationwide, more than one-quarter of hospital-based general practitioners who take over for patients’ primary care doctors to manage inpatient care say their average patient load exceeds safe levels multiple times per month, according to a new Johns Hopkins study. Continue reading
