Forsyth scientists gain new understanding of latent tuberculosis

Scientists at the Forsyth have gained new insight on how Tuberculosis (TB) remains a global epidemic. Although drugs have been available to fight TB for 50 years, the disease still infects nearly 2.2 billion people worldwide and causes 1.7 million annual deaths. This is largely attributed to the bacteria's ability to stay dormant in the human body and later resurface as active disease. The Forsyth team, and its collaborators from Stanford University, has recently discovered that Mycobacterium tuberculosis, the bacteria that causes TB, can lay dormant and thrive within ...

Itching for new help for eczema: Recently identified immune cells possible therapeutic target

PHILADELPHIA - The increasing incidence of allergic skin diseases, and the accompanying economic burden and heightened risk of developing other allergic conditions, have spurred researchers to look for better ways to control these immune system-based disorders. Atopic dermatitis, more commonly called eczema, now affects 10 to 20 percent of children in the United States and direct health-care costs exceed $3 billion, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases. What's more, up to 50 percent of children with atopic dermatitis ...

Scientists may have received millions in duplicate funding

Big Data computation at the Virginia Bioinformatics Institute at Virginia Tech reveals that over the past two decades funding agencies may have awarded millions and possibly billions of dollars to scientists who submitted the same grant request multiple times — and accepted duplicate funding. An analysis led by Harold R. Garner, a professor at Virginia Tech, not only indicates that millions in funding may have been granted and used inappropriately, it points to techniques to uncover existing instances of duplicate funding and ways to prevent it in the future. The analysis ...

Setting the stage for a new paradigm in treatment of heart failure

CHAPEL HILL, N.C. – Despite a substantial increase in the number of people suffering the debilitating and often deadly effects of heart failure, treatments for the condition have not advanced significantly for at least 10 years. An analysis by researchers at the University of North Carolina School of Medicine shows new breakthroughs could be closer than we thought. The analysis points to striking similarities between heart cells in patients with heart failure and brain cells in patients with Alzheimer's disease, raising the possibility that some treatment approaches being ...

Current evidence does not support selenium for preventing heart disease in well-nourished adults

A systematic review published today in The Cochrane Library finds that in well-nourished adults current evidence does not support selenium for preventing heart disease. The review suggests that taking selenium supplements does not reduce a person's risk of developing heart disease, although most evidence is currently limited to healthy American adults. Diet is a key factor influencing heart disease risk. Selenium is one dietary element that could potentially play a role in preventing heart disease by protecting against oxidative stress and inflammation. It is a common ...

Brain activity study lends insight into schizophrenia

Magnetic fields produced by the naturally occurring electrical currents in the brain could potentially be used as an objective test for schizophrenia and help to better understand the disease, according to new research published today. A team of researchers from Plymouth and Spain have used the non-invasive magnetoencephalogram (MEG) technique to find two spectral features that are significantly different in schizophrenia patients compared to healthy control subjects. Furthermore, they found that there were four spectral features in the brain signals of schizophrenia ...

Chronic hepatitis C: Interferon may be harmful in re-treatment

People with hepatitis C and chronic liver disease who relapsed or failed to respond to initial treatment are unlikely to improve on interferon retreatment. In fact, they may face an increased risk of dying sooner, and are likely to experience a variety of adverse effects, according to an updated systematic review published in The Cochrane Library. Hepatitis C affects around 170 million people worldwide. In some cases, infection leads to chronic liver disease, liver failure or liver cancer, eventually resulting in death. Treatment is based on antiviral drugs. Interferon ...

New research shows complexity of global warming

Global warming from greenhouse gases affects rainfall patterns in the world differently than that from solar heating, according to a study by an international team of scientists in the January 31 issue of Nature. Using computer model simulations, the scientists, led by Jian Liu (Chinese Academy of Sciences) and Bin Wang (International Pacific Research Center, University of Hawaii at Manoa), showed that global rainfall has increased less over the present-day warming period than during the Medieval Warm Period, even though temperatures are higher today than they were then. ...

Tuberculosis may lurk in bone marrow stem cells of infected patients, Stanford researchers say

STANFORD, Calif. - Tuberculosis is a devastating disease that kills nearly 2 million people worldwide each year. Although antibiotics exist that can ameliorate the symptoms, the courses of therapy last for months and don't completely eradicate the disease, which frequently recurs years or decades after the initial treatment. Now, in a classic case of bench-to-bedside research, scientists at the Stanford University School of Medicine have discovered a possible reason for the disease's resistance: The ability of the tuberculosis bacteria to infiltrate and settle down in ...

Antibiotics cut death rate for malnourished children

Severely malnourished children are far more likely to recover and survive when given antibiotics along with a therapeutic peanut-based food than children who are simply treated with the therapeutic food alone, researchers at Washington University School of Medicine in St. Louis have found. "The findings are remarkable," says Indi Trehan, MD, lead author of the research, published Jan. 31 in The New England Journal of Medicine. "Based on previous research, we didn't think there would be much benefit from antibiotics. We did not at all expect to see a drop in the death ...

Vultures foraging far and wide face a poisonous future

A first ever study of the range and habits of white-backed vultures across southern Africa shows that they often shun national parks, preferring to forage further afield on private farmland. This behaviour and their tendency to scavenge in groups, means that vultures risk encountering dead cattle that have been administered veterinary drugs that are poisonous to them, or even poisoned carcasses intended to control other carnivores such as jackals. The research, using Global Positioning System (GPS) satellite transmitters to track the movements of adolescent vultures, ...

Disasters can prompt older children to be more giving, younger children to be more selfish

A natural disaster can bring out the best in older children, prompting 9-year-olds to be more willing to share, while 6-year-olds become more selfish. Researchers at the University of Toronto, the University of Chicago, and Liaoning Normal University made this finding in a rare natural experiment in China around the time of a horrific earthquake. A crucial difference between the two age groups emerged one month after the disaster. The 6-year-olds' willingness to share in a test measuring altruism dropped by a third, while among 9-year-olds, willingness to give to others ...
