Toxic substances, nutrient shortage, viral infection, heat and many other events trigger stress responses in cells. In such cases, the affected cells launch a programme which tries to protect them against stress-related damages. They usually ramp down the production of endogenous proteins to save resources which they later need to repair cell damages or to survive under the stress conditions for some time.
Based on complex simulations of quantum chromodynamics performed using the K computer, one of the most powerful computers in the world, the HAL QCD Collaboration, made up of scientists from the RIKEN Nishina Center for Accelerator-based Science and the RIKEN Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) program, together with colleagues from a number of universities, have predicted a new type of "dibaryon"--a particle that contains six quarks instead of the usual three.
Led by the London School of Hygiene & Tropical Medicine, the study examined the health records of almost 2m people in the UK. Patients with severe eczema were found to experience a 20% increased risk of stroke (389/19,622 patients with severe eczema v 21,387/1,528,477 without), 70% increased risk of heart failure (419/19,624 v 16,983/1,528,477), and 40-50% increased risk of the remaining cardiovascular outcomes, including unstable angina, myocardial infarction, atrial fibrillation and cardiovascular death, compared to patients without eczema.
Students from some of England's worst performing secondary schools who enroll on medical degrees with lower A Level grades, on average, do at least as well as their peers from top performing schools, a new study has revealed.
The research also found that students from poorly performing schools who match the top A Level grades achieved by pupils from the best performing schools, go on to do better during a medical degree.
The authors of the research are now calling for medical school entry criteria to be relaxed for all pupils applying from low-performing schools.
Psychologists at the University of Sussex have found a link between depression and an acceleration of the rate at which the brain ages. Although scientists have previously reported that people with depression or anxiety have an increased risk of dementia in later life, this is the first study that provides comprehensive evidence for the effect of depression on decline in overall cognitive function (also referred to as cognitive state), in a general population.
Not only is smoking bad for your lungs, but new research shows that components in cigarette smoke directly damages your muscles. The research, published in The Journal of Physiology, indicates that smoking decreases the number of small blood vessels that bring oxygen and nutrients to muscles in the legs.
We know that smoking limits a person's ability to exercise because it makes their muscles weaker. It was widely believed this muscle weakness is because the lungs become inflamed and eventually destroyed by habitual smoking, therefore limiting activity and exercise.
A lot can happen at 160 degrees Fahrenheit: Eggs fry, salmonella bacteria dies, and human skin will suffer third-degree burns. If a car is parked in the sun on a hot summer day, its dashboard can hit 160 degrees in about an hour. One hour is also about how long it can take for a young child trapped in a car to suffer heat injury or even die from hyperthermia.
Combining data from electronic health records with results from standardized depression questionnaires better predicts suicide risk in the 90 days following either mental health specialty or primary care outpatient visits, reports a team from the Mental Health Research Network, led by Kaiser Permanente research scientists.
Researchers at Children's Hospital Colorado (Children's Colorado) and the University of Colorado School of Medicine have found that taking a specially formulated antioxidant-enriched multivitamin may decrease respiratory illnesses in people with cystic fibrosis (CF).
TAMPA, Fla. (May 23, 2018)- Music can be the ultimate mood setter. Faster beats ignite excitement, while slower songs help one relax. And that makes all the difference in what we order from restaurant menus.
AURORA, Colo. (May 23, 2018) - Research by physician-scientists at the University of Colorado Anschutz Medical Campus offers hope for improved quality of life for people who rely on intravenous nutrition due to intestinal damage.
Karim C. El Kasmi, MD, PhD, assistant professor of pediatrics, and Ronald Sokol, MD, professor of pediatrics, are authors of an article in the April 2018 Nature Communications that sheds light on the underlying cause of intestinal failure-associated liver disease and suggests new therapeutic approaches.
Researchers at Columbia Engineering have demonstrated, for the first time, a chip-based dual-comb spectrometer in the mid-infrared range, that requires no moving parts and can acquire spectra in less than 2 microseconds. The system, which consists of two mutually coherent, low-noise, microresonator-based frequency combs spanning 2600 nm to 4100 nm, could lead to the development of a spectroscopy lab-on-a-chip for real-time sensing on the nanosecond time scale.
A new Presidential Studies Quarterly article analyzes the effects of the early Trump Presidency on public attitudes toward the Republican Party.
Survey data indicate that Trump appears to be widening the demographic and cultural differences between ordinary Republicans and Democrats, exacerbating the gender, age, and racial gaps between the party coalitions in a way that threatens the long-term vitality of his party.
People in centenarians' close social networks are often not aware of their thoughts on end-of-life issues, a new Journal of the American Geriatrics Society study reveals.
Groundbreaking research shows that neurological health depends as much on signals sent by the body's large, leg muscles to the brain as it does on directives from the brain to the muscles.
