Vegetarianism can reduce risk of heart disease by up to a third

The risk of hospitalisation or death from heart disease is 32% lower in vegetarians than people who eat meat and fish, according to a new study from the University of Oxford.

Heart disease is the single largest cause of death in developed countries, and is responsible for 65,000 deaths each year in the UK alone. The new findings, published in the American Journal of Clinical Nutrition, suggest that a vegetarian diet could significantly reduce people's risk of heart disease.

How does fibrosis occur in Crohn's disease?

New research has shown that a protein, known as IL-13, could be the key to the development of fibrosis in Crohn's disease. This breakthrough could help to advance new medicines to treat people suffering with the disease.

Snails signal a humid Mediterranean

An international team of researchers has shown that old wives' tales that snails can tell us about the weather should not be dismissed too hastily.

While the story goes that if a snail climbs a plant or post, rain is coming, research led by the University of York goes one better: it shows snails can provide a wealth of information about the prevailing weather conditions thousands of years ago.

A new genre of 'intelligent' micro- and nanomotors

Enzymes, workhorse molecules of life that underpin almost every biological process, may have a new role as "intelligent" micro- and nanomotors with applications in medicine, engineering and other fields. That's the topic of a report in the Journal of the American Chemical Society, showing that single molecules of common enzymes can generate enough force to cause movement in specific directions.

Aging cells lose their grip on DNA rogues

PROVIDENCE, R.I. [Brown University] — Even in our DNA there is no refuge from rogues that prey on the elderly. Parasitic strands of genetic material called transposable elements — transposons — lurk in our chromosomes, poised to wreak genomic havoc. Cells have evolved ways to defend themselves, but in a new study, Brown University researchers describe how cells lose this ability as they age, possibly resulting in a decline in their function and health.

How our cells cope with toxic small molecules

In this week's issue of the prestigious journal Nature Chemical Biology, scientists Carole Linster (University of Luxembourg), Emile Van Schaftingen (Louvain University), and Andrew D. Hanson (University of Florida, Gainesville) review an important, but so far neglected, part of metabolism, namely metabolite damage-control.

TV viewing and sedentary lifestyle in teens linked to disease risk in adulthood

A team of scientists at Umeå University, in collaboration with colleagues in Melbourne, Australia, have found that television viewing and lack of exercise at age 16 is associated with the risk of developing metabolic syndrome at 43 years age.

Metabolic syndrome is a name for the disorder of metabolism - a combination of abdominal obesity, elevated blood lipids, hypertension and impaired glucose tolerance - which provides for a significantly increased risk of developing type 2 diabetes, stroke and cardiovascular disease.

Study finds little progress in participation of early-career RNs in hospital QI

Nurses are the largest group of health care providers in the U.S., and health care leaders and experts agree that engaging registered nurses (RNs) in quality improvement (QI) efforts is essential to improving our health care system, patient care and our nation's health. Unfortunately, despite studies demonstrating the value of nurse-led quality improvement efforts, far too few nurses are involved in these efforts, and the number is not growing, according to a study published in the Journal of Nursing Care Quality.

Campus as laboratory: U-M student biologists use Diag trees to help solve gypsy moth mystery

ANN ARBOR—Working beneath the towering oaks and maples on the University of Michigan's central campus Diag, undergraduate researchers and their faculty adviser helped explain an observation that had puzzled insect ecologists who study voracious leaf-munching gypsy moth caterpillars.

The caterpillars, which defoliate and sometimes kill stands of trees in the Upper Midwest and the Northeast, are especially fond of oaks, but sugar maple trees appear to be relatively resistant to the European pest.

5-year follow-up - over half of all ACL reconstructions could be avoided

"We have continued with our study and for the first time are able to present a five-year follow-up on the need for and results of ACL surgery as compared with physiotherapy. The findings have been published in the British Medical Journal and are basically unchanged from 2010. This will no doubt surprise many people, as we have not seen any difference in the incidence of osteoarthritis", says Richard Frobell, one of the researchers behind the study, who is an associate professor at Lund University and a clinician at the orthopaedic department, Helsingborg Hospital.

Toward a better cyanide antidote for terrorist attacks and other mass casualty events

In an advance toward closing a major gap in defenses against terrorist attacks and other mass casualty events, scientists are reporting discovery of a promising substance that could be the basis for development of a better antidote for cyanide poisoning. Their report, which describes a potential antidote that could be self-administered, much like the medication delivered by allergy injection pens, appears in ACS' Journal of Medicinal Chemistry.

UCSB research provides insight into mechanics of arthritis

(Santa Barbara, Calif.) –– A new, noninvasive, and low-cost method for the early detection and monitoring of osteoarthritis (arthritis caused by wear and tear) may be on its way, thanks to research by UC Santa Barbara scientists from the Department of Chemical Engineering and the Department of Materials.

New target to stop cancer's spread discovered by Georgia State scientists

Disrupting a key interaction between two types of proteins in cells inhibits the spread of cancerous cells, providing researchers with a new pathway toward developing cancer-fighting drugs, according to new findings by Georgia State University scientists.

Cell migration is essential for the spread of cancerous cells, also known as metastasis, as well as for other diseases. The research team in the labs of Zhi-Ren Liu, professor of biology, and Jenny Yang, professor of biochemistry, studied the interaction of two molecules, p68 RNA helicase and calcium-calmodulin.

Erectile dysfunction drug also helps men ejaculate and orgasm

NEW YORK (January 30, 2013) -- New data suggests the erectile dysfunction (ED) drug Cialis may also be beneficial in helping men who have problems with ejaculation and orgasm, report researchers from NewYork-Presbyterian Hospital/Weill Cornell Medical Center in the February issue of the British Journal of Urology International. Cialis is currently approved for the treatment of ED, benign prostate hypertrophy (BPH) and for treatment of men with both conditions.

More sex for married couples with traditional divisions of housework

Married men and women who divide household chores in traditional ways report having more sex than couples who share so-called men's and women's work, according to a new study co-authored by sociologists at the University of Washington.

Other studies have found that husbands got more sex if they did more housework, implying that sex was in exchange for housework. But those studies did not factor in what types of chores the husbands were doing.
