Clinical studies by scientists at British American Tobacco indicate that when smokers switched completely from conventional cigarettes to glo, their exposure to certain harmful chemicals was significantly reduced. In some cases, the reductions were the same as those in smokers who quit altogether. These data suggest the potential of glo as a reduced-risk product. glo is a tobacco heating product designed to heat rather than burn tobacco. Tests show that glo vapour has around 90-95 percent less toxicants than smoke.
Many hospital patients get medicine or nutrition delivered straight into their bloodstream through a tiny device called a PICC. In just a decade, it's become the go-to device for intravenous care. But a new study finds that one in every four times a PICC gets inserted, the patient didn't need it long enough to justify the risks it can pose. And nearly one in ten of those patients suffered a complication linked to the device.
Researchers from Arizona State University School of Life Sciences and Smithsonian Tropical Research Institute have sequenced the complete genetic code -- the genome -- of several vertebrate species from Panama. They found that changes in genes involved in the interbrain (the site of the pineal gland and other endocrine glands), for color vision, hormones and the colorful dewlap that males bob to attract females, may contribute to the formation of boundaries between species. Genes regulating limb development also evolved especially quickly.
Soil pathogen testing -- critical to farming, but painstakingly slow and expensive -- will soon be done accurately, quickly, inexpensively and onsite, thanks to research that Washington State University scientists plant pathologists are sharing.
Researchers at Brigham and Women's Hospital (BWH) have discovered a new cellular and molecular pathway that regulates CD4+ T cell response -- a finding that may lead to new ways to treat diseases that result from alterations in these cells.
A Syracuse University researcher explores the impact of de-icing salt from roads and highways on a local watershed. She says their findings make her 'cautiously optimistic' about the watershed's future surface-water chloride concentrations.
As described in a study published today in Nature Communications, researchers at the New York Genome Center (NYGC) and New York University (NYU) have taken steps to facilitate broad access to single-cell sequencing by developing a 3-D-printed, portable and low-cost microfluidic controller. To demonstrate the utility of the instrument in clinical environments, the researchers deployed the device to study synovial tissue from patients with rheumatoid arthritis (RA) at the Hospital for Special Surgery (HSS).
At most US maternity units, women in labor are put on nil per os (NPO) status -- they're not allowed to eat or drink anything, except ice chips. But new nursing research questions that policy, showing no increase in risks for women who are allowed to eat and drink during labor. The study appears in the March issue of the American Journal of Nursing, published by Wolters Kluwer.
New research published in the Feb. 23 issue of the Journal of Biological Chemistry identifies an enzyme that turns off transglutaminase 2, potentially paving the way for new treatments for celiac disease.
New study from MIT and CNRS shows a way to dial down the urban heat island effects that can pump up city temperatures, through different city planning based on classical physics formulas.
