The cellular process autophagy appears to not work properly, contributing to the destruction of insulin-producing beta cells
People with Type 2 diabetes have an excess of a protein called islet amyloid polypeptide, or IAPP, and the accumulation of this protein is linked to the loss of insulin-producing pancreatic beta cells.
Researchers have uncovered a way the malaria parasite becomes resistant to an investigational drug. The discovery, at Washington University School of Medicine in St. Louis, also is relevant for other infectious diseases including bacterial infections and tuberculosis.
The study appears July 24 in Nature Communications.
Traditional methods of characterising and detecting bacteria are often slow and time-consuming. Therefore, development of new methods of characterising and detecting illness-causing microorganisms is very important for improving food safety.
Trine Hansen, PhD student at the National Food Institute, has studied new methods of characterising Salmonella in pork meat processing and detecting unknown bacteria in water, feed and food samples.
It is seldom sufficient to read the declaration of contents if you need to know precisely what substances a product contains. In fact, to do this you need to be a highly skilled chemist or to have genuine X-ray vision so that you can look directly into the molecular structure of the various substances. Christian Grundahl Frankær, a Postdoc at DTU Chemical Engineering, is almost both, as he has developed a method that allows him to use X-rays to look deep into biological samples.
The 'Fingerprints' of a Substance
New research from the University of Sydney Voice Research Laboratory has discovered unique vocal cord vibration patterns might be the secret behind a good radio voice.
The world-first study filmed the vocal folds of 16 male radio performers, including announcers, broadcasters, newsreaders and voice-over artists and found their vocal folds move and close faster than non-broadcasters.
Philadelphia – Students graduating from U.S. medical schools in 2012 feel they've received a better education in health policy issues than graduates surveyed in 2008, according to a multi-center study led by the Perelman School of Medicine at the University of Pennsylvania, and published online this month in Academic Medicine. The study applied a new framework for teaching and evaluating perceptions of training in health policy, first proposed by the authors in a 2011 perspective published in the New England Journal of Medicine.
The immune system has evolved to recognize and respond to threats to health, and to provide life-long memory that prevents recurrent disease. A detailed understanding of the mechanism underlying immunologic memory, however, has remained elusive. Since 2001, various lines of research have converged to support the hypothesis that the persistence of immune memory arises from a reservoir of immune cells with stem-cell-like potential. Until now, there was no conclusive evidence, largely because experiments could only be carried out on populations of cells.
Odds are, there’s a virus living inside your gut that has gone undetected by scientists for decades. A new study led by researchers at San Diego State University has found that more than half the world’s population is host to a newly described virus, named crAssphage, which infects one of the most common types of gut bacteria, Bacteroidetes. This phylum of bacteria is thought to be connected with obesity, diabetes and other gut-related diseases. The research appears today in Nature Communications.
Washington, DC (July 21, 2014) – It seems common practice. After a long day at work, sometimes you just want to turn on the TV or play a video game to relax, decompress. This is supposed to make you feel better. But, a recent study published in the Journal of Communication, by researchers at the Johannes Gutenberg University Mainz, Germany, and VU University Amsterdam, found that people who had high stress levels after work and engaged in television viewing or video game play didn't feel relaxed or recovered, but had high levels of guilt and feelings of failure.
Children, teenagers and young adults living near Sellafield or Dounreay since the 1990s are not at an increased risk of developing cancer according to research published in the British Journal of Cancer today* (Wednesday).
(Philadelphia, PA) – Asking patients if a suspicious skin lesion is painful or itchy may help doctors decide whether the spot is likely to be cancerous, according to a new study headed by Gil Yosipovitch, MD, Chairman of the Department of Dermatology at Temple University School of Medicine.
Bottom Line: An enhanced recovery program for patients after colorectal surgery appears to be feasible in a community hospital setting after having been shown to be successful in international and academic medical centers.
Author: Cristina B. Geltzeiler, M.D., of Oregon Health and Science University, Portland, and colleagues.
Bottom Line: A postoperative pneumonia prevention program for patients in the surgical ward at a California Veterans Affairs hospital lowered the case rate for the condition, which can cause significant complications and increase the cost of care.
Author: Hadiza S. Kazaure, M.D., of the Stanford University School of Medicine, California, and colleagues.
Background: Pneumonia is a common infection that accounts for about 15 percent of all hospital-acquired infections and as much as 3.4 percent of complications among surgical patients.
In lab experiments using tissue samples cultured from cystic fibrosis patients, scientists at the UNC School of Medicine and the UNC Marsico Lung Institute have shown that a new CF drug counteracts the intended beneficial molecular effect of another CF drug.
The finding, published today in the journal Science Translational Medicine, shows how a mutant CFTR protein becomes unstable and loses its ability to function properly when in the presence of the two drugs. The research offers several insights into how novel CF pharmacotherapies could be improved.
