Harvard Medical School researchers have identified the mechanism behind red blood cell specialization and revealed that it is controlled by an enzyme called UBE2O. This finding could spark the development of new treatments for blood disorders and cancers.
Clinical signs such as gastrointestinal problems may be better predictors of mortality in neonatal calves with diarrhea than blood pH levels and other laboratory findings, suggests a new study co-written by University of Illinois veterinary medicine dean Peter Constable; Florian M. Trefz and Annette Lorch, both of the Center of Veterinary Clinical Medicine at Ludwig Maximilian University of Munich; and Ingrid Lorenz, of the Bavarian Animal Health Service.
Smokers were found to be 20 percent more likely to quit smoking when packs of cigarettes cost just one dollar more, according to a new public health study out of Drexel University.
The American Society for Radiation Oncology (ASTRO) applauds the United States Nuclear Regulatory Commission for yesterday's announcement of a final rule that updates the definition of medical events for permanent implant brachytherapy and protects patients' access to this treatment.
Researchers at UC San Diego Moores Cancer Center, with colleagues from Memorial Sloan Kettering Cancer Center and Fox Chase Cancer Center, have determined that a specific region of the small bowel, called the duodenal-jejunal flexure or DJF, shows a high frequency of gastrointestinal stromal tumors (GISTs) with mutations of the NF1 gene.
Leading pediatrics and sleep associations agree: Teens shouldn't start school so early. Yet University of Michigan research finds parents are split almost down the middle on whether they support delays in school start times that might permit their 13- to 17-year-olds to sleep later on school days.
A recent study found an elevated risk of heart failure in more than half of older individuals, and this risk was significantly associated with vitamin D deficiency.
Researchers at Brigham and Women's Hospital and CHERG used the first international, multi-ethnic birth weight standard, known as the INTERGROWTH-21st, to describe the global burden of suboptimal fetal growth.
Elucidating how body parts in their earliest recognizable form are assembled in tetrapods during development is essential for understanding the nature of morphological evolution. Nagoya University researchers found in eight tetrapod species that the position of the sacral vertebrae and the hindlimbs is determined by the initiation timing of Gdf11 gene expression. This will contribute to a forthcoming model explaining the coupling of spine and hindlimb positioning - a major step in fully understanding tetrapod evolution.
Scientists of the German Center for Diabetes Research (DZD) in Tübingen discovered that a fatty liver can cause damage to other organs. In two just-published studies they demonstrate the effects of fatty liver disease on the function of the hormone-producing islet cells in the pancreas and on renal function.
