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.
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.
Researchers from the University of Freiburg are mapping the distribution of all proteins in mitochondria for the first time.
Chemical engineers at the University of Notre Dame have discovered a catalytic process that could help curb emissions of nitrogen oxides from diesel-powered vehicles, a priority air pollutant that is a key ingredient in smog.
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.
Avian flu can be transmitted from birds to humans; transmission among humans, however, is limited. The reason may be an eggshell-like mineral layer that the virus acquires due to the high calcium concentration in the intestines of birds. As reported by Chinese researchers in the journal Angewandte Chemie, these mineralized viruses are significantly more infectious and, in addition, more robust and heat stable than the native viruses.
Artificial neural networks decode brain activity during performed and imagined movements.
A theory that has gained considerable attention in international media, including Newsweek and the CBS broadcast 60 minutes, suggest that antidepressant drugs, such as the SSRIs, do not exert any actual antidepressant effect. A research group at the Sahlgrenska Academy has now analyzed data from clinical trials and can rebut this theory.
Researchers at Nagoya University revealed that a molecule called Daple is essential for the correct orientation and coordinated beating of cilia on the surface of cells lining ventricles in the brain. Without Daple, the cilia develop a random arrangement and cannot produce a uniform flow of CSF. This in turn leads to a build-up of fluid, which is associated with swelling of the head, known as hydrocephalus.
