"We estimate that three percent of all premature deaths can be attributed to the high consumption of processed meat," summarizes Sabine Rohrmann from the Institute of Social and Preventive Medicine at the University of Zurich. Teaming up with research colleagues from ten countries, she has been studying the link between the consumption of processed meat and the risk of mortality as part of a Europe-wide study with around 450,000 participants.
Anyone whose hand or foot has "fallen asleep" has an idea of the numbness and tingling often experienced by people with peripheral nerve damage. The condition also can cause a range of other symptoms, including unrelenting pain, stinging, burning, itching and sensitivity to touch.
Although peripheral neuropathies afflict some 20 million Americans, their underlying causes are not completely understood. Much research has focused on the breakdown of cellular energy factories in nerve cells as a contributing factor.
A research team at the University of Guelph has developed a new line of transgenic "Enviropigs." The new line of pigs is called the Cassie line, and it is known for passing genes on more reliably. The results of this project were published ahead of print in the Journal of Animal Science.
Flu viruses are a major cause of death and sickness around the world, and antiviral drugs currently do not protect the most seriously ill patients. A study published March 7th by Cell Press in the journal Cell reveals that a compound derived from fats found in fish oils prevents death in influenza-virus-infected mice, even at advanced stages of disease. The study offers a promising strategy for the treatment of patients with severe influenza virus infections.
When animals like dogs or rats sniff one another, there might be more going on than you'd think. Research reported in Current Biology, a Cell Press publication, on March 7th finds in rats that those sniffing behaviors communicate information about an individual's social status. In those encounters, more dominant rats act as primary sniffers, while subordinate sniffees actually slow their breath.
An Australian researcher has found the third and final missing piece in the genetic puzzle of an unusual form of hemophilia, more than 20 year after he discovered the first two pieces.
Professor Merlin Crossley, of the University of New South Wales, and his international team studied the blood-clotting disorder, hemophilia B Leyden, which is unusual because symptoms improve after puberty.
USC scientists have discovered how two different structural apparatuses collaborate to protect repetitive DNA when it is at its most vulnerable – while it is being unzipped for replication.
Using the technique that created Dolly the sheep, researchers from the RIKEN Center for Developmental Biology in Kobe, Japan have identified a way to produce healthy mouse clones that live a normal lifespan and can be sequentially cloned indefinitely.
Their study is published today in the journal Cell Stem Cell.
In an experiment that started in 2005, the team led by Dr. Teruhiko Wakayama has used a technique called somatic cell nuclear transfer (SNCT) to produce 581 clones of one original 'donor' mouse, through 25 consecutive rounds of cloning.
PHILADELPHIA – It happens to everyone: You stay up late one night to finish an assignment, and the next day, you're exhausted. Humans aren't unique in that; all animals need sleep, and if they don't get it, they must make it up.
The biological term for that pay-the-piper behavior is "sleep homeostasis," and now, thanks to a research team at the Perelman School of Medicine, University of Pennsylvania, one of the molecular players in this process has been identified – at least in nematode round worms.
NEW YORK, 7 March 2013 – Between 2011 and 2020, more than 140 million girls will become child brides, according to United Nations Population Fund (UNFPA).
If current levels of child marriages hold, 14.2 million girls annually or 39,000 daily will marry too young.
Furthermore, of the 140 million girls who will marry before the age of 18, 50 million will be under the age of 15.
CHAPEL HILL, N.C. - Locally advanced squamous cell carcinoma of the head and neck is a potentially curable disease in nearly every patient at the time of diagnosis, yet despite the most aggressive efforts, up to 30-50 percent of patients may ultimately succumb to the disease. For diseases where outcomes are so uncertain, medical science frequently addresses the need by intensifying therapy.
Cold Spring Harbor, NY – In collaboration with colleagues at Cornell University, a team of cancer researchers at Cold Spring Harbor Laboratory (CSHL) has discovered cells with stem-cell properties in the ovary that can mutate to form tumors.
The team demonstrated that when two important tumor suppressor genes are inactivated, a previously unknown subset of ovarian stem-like epithelial cells undergoes cancerous transformation. The findings, published today in the journal Nature, have important implications for our knowledge about ovarian cancer.
SAN FRANCISCO (March 7, 2013) — Modest financial incentives offered over an extended period of time were significantly more likely to encourage sustained participation in a weight-loss program and long-term maintenance of weight loss than an identical program that did not offer financial rewards, according to a study being presented at the American College of Cardiology's 62nd Annual Scientific Session.
SAN FRANCISCO (March 7, 2013) — Being overweight, especially from a young age, appears to lead to a bigger heart later in life, a condition that has been linked to serious heart problems and even death, according to research being presented at the American College of Cardiology's 62nd Annual Scientific Session.
SAN FRANCISCO (March 7, 2013) — Suppressing a hunger-stimulating hormone with a minimally invasive procedure was safe in humans and led to significant weight loss for at least six months in a small preliminary study being presented at the American College of Cardiology's 62nd Annual Scientific Session.
More than two-thirds of American adults are overweight or obese, conditions that total more than $147 billion in medical costs each year. Excess weight also increases the risk for other conditions, such as high blood pressure, high cholesterol and type 2 diabetes.
