Football Scores a Health Hat Trick for Hypertensive Men

Playing football (soccer) could be the best way for people with high blood pressure, known as hypertension, to improve their fitness, normalise their blood pressure and reduce their risk of stroke, according to research published today (Monday 15 October 2012) in the journal Medicine and Science in Sports and Exercise.

Research from Universities of Exeter and Copenhagen, and Gentofte University Hospital in Denmark suggests football training prevents cardiovascular disease in middle-aged men with hypertension and is more effective than healthy lifestyle advice currently prescribed by GPs.

After six months of football training, three out of four men in this study had blood pressure within the normal, healthy range. (more…)

Engineered Flies Spill Secret of Seizures

Scientists have observed the neurological mechanism behind temperature-dependent — febrile — seizures by genetically engineering fruit flies to harbor a mutation analogous to one that causes epileptic seizures in people. In addition to contributing the insight on epilepsy, their new study highlights the first use of genetic engineering to swap a human genetic disease mutation into a directly analogous gene in a fly.

PROVIDENCE, R.I. [Brown University] — In a newly reported set of experiments that show the value of a particularly precise but difficult genetic engineering technique, researchers at Brown University and the University of California–Irvine have created a Drosophila fruit fly model of epilepsy to discern the mechanism by which temperature-dependent seizures happen.

UCLA Scientists Discover Sleeping Brain Behaves as If It’s Remembering Something

UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer’s disease during sleep. They discovered that this region, called the entorhinal cortex, behaves as if it’s remembering something, even during anesthesia–induced sleep — a finding that counters conventional theories about sleep-time memory consolidation.

Doctors Wary of Studies Funded by Pharmaceutical Industry, Study Shows

Physicians are about half as willing to prescribe drugs tested in pharmaceutical-industry funded trials than those in NIH-funded studies, a new study finds.

Physicians are less likely to trust the results of clinical trials when they know those trials were funded by pharmaceutical companies, regardless of the quality of the research, a recent study in the New England Journal of Medicine shows.

The study, led by Dr. Aaron Kesselheim of the Harvard Medical School in Boston and co-authored by University of Arizona associate professor of law Christopher Robertson, evaluated physicians’ confidence in the results of drug trials conducted with a high, medium or low level of methodological rigor. It then looked at how their confidence in those same results changed when a trial’s funding source was revealed as either the National Institutes of Health or a company in the pharmaceutical industry, versus when no funding source was disclosed.

COLUMBUS, Ohio – Taking enough omega-3 fatty acid supplements to change the balance of oils in the diet could slow a key biological process linked to aging, new research suggests.

The study showed that most overweight but healthy middle-aged and older adults who took omega-3 supplements for four months altered a ratio of their fatty acid consumption in a way that helped preserve tiny segments of DNA in their white blood cells. (more…)

For Some Women, Genes May Influence Pressure to Be Thin

EAST LANSING, Mich. — Genetics may make some women more vulnerable to the pressure of being thin, a study led by Michigan State University researchers has found.

From size-zero models to airbrushed film stars, thinness is portrayed as equaling beauty across Western culture, and it’s an ideal often cited as a cause of eating disorder symptoms in young women. The researchers focused on the potential psychological impact of women buying into this perceived ideal of thinness, which they call thin-ideal internalization. Changes in self-perception and behavior, caused by this idealization, can lead to body dissatisfaction, a preoccupation with weight and other symptoms of eating disorders. (more…)
