Health disparities not connected to lack of exercise, Vanderbilt study finds

Health disparities between white and black adults in the South are not connected to a lack of exercise but more likely related to other factors such as access to health care, socioeconomic status and perhaps genetics, according to a Vanderbilt study published in the journal PLOS ONE.

Ribavirin, interferon-alpha 2b inhibit virus replication in cell culture, NIH study finds

National Institutes of Health scientists studying an emerging coronavirus have found that a combination of two licensed antiviral drugs, ribavirin and interferon-alpha 2b, can stop the virus from replicating in laboratory-grown cells.

Study finds dietary supplements accounted for more than half the Class 1 drugs recalled by FDA

Dietary supplements accounted for more than half the Class 1 drugs recalled by the U.S. Food and Drug Administration from 2004-12, meaning they contained substances that could cause serious health problems or even death, a new study from St. Michael's Hospital has found.

North American scientists chart new territory in immunity research

Cracking the DNA code for a complex region of the human genome has helped 14 North American scientists, including five at Simon Fraser University, chart new territory in immunity research.

Researchers study new ways of taking advantage of caffeine's lethal effects on cancer cells

Researchers from the University of Alberta are abuzz after using fruit flies to find new ways of taking advantage of caffeine's lethal effects on cancer cells-results that could one day be used to advance cancer therapies for people.

Antibiotic resistance: A growing problem in hospital and outpatient settings

A new study concludes that problems with antibiotic resistance faced by outpatients may be as bad as those in hospitalized patients, and that more studies of outpatients are needed - both to protect their health and to avoid inappropriate or unnecessary drug use.

Research findings provide new hope for people suffering from dry eye disease

Natural lubricants play an important role in health, including a well-known effect to help prevent osteoarthritis in knee and ankle joints. However, much is still unknown about their role and function in other areas of the body.

Elevated responsivity of reward regions in the brain increases risk for future substance use

Do people get caught in the cycle of overeating and drug addiction because their brain reward centers are over-active causing them to experience greater cravings for food or drugs? In a unique prospective study Oregon Research Institute senior scientist Eric Stice, Ph.D., and colleagues tested this theory, called the reward surfeit model.

Study highlights how genes can acquire, adapt to different roles in human evolution

Researchers have designed a method that can universally test for evolutionary adaption, or positive (Darwinian) selection, in any chosen set of genes, using re-sequencing data such as that generated by the 1000 Genomes Project.

Tel Aviv University researcher reveals the missing link between brain patterns and Alzheimer's

Evidence indicates that the accumulation of amyloid-beta proteins, which form the plaques found in the brains of Alzheimer's patients, is critical for the development of Alzheimer's disease, which impacts 5.4 million Americans.

Scientists probe source of pulsing signal in the sleeping brain

New findings clarify where and how the brain's "slow waves" originate. These rhythmic signal pulses, which sweep through the brain during deep sleep at the rate of about one cycle per second, are assumed to play a role in processes such as consolidation of memory.

Three missense variants of BRCA1 gene linked to breast or ovarian cancer risk, study shows

Researchers of the hereditary cancer research group at the Bellvitge Biomedical Research Institute and the Catalan Institute of Oncology conducted a functional and structural study of seven missense variants of the BRCA1 gene concluding that three of these variants are pathogenic, linked to the risk of suffering breast or ovarian cancer.

Research shows English-speaking U.S. Hispanics less likely to engage in skin cancer prevention practices

Research from The Cancer Institute of New Jersey shows that U.S. Hispanics who speak English are less likely to engage in skin cancer prevention practices and more likely to put themselves at risk for skin cancer as compared to Spanish-speaking Hispanics who live in this country.

Painful effects of harsh discipline can be moderated by a loving mother

The use of harsh discipline of unwanted behaviour in children has long been controversial. Whether verbal (insults, disparaging remarks, threats) or physical (slapping/spanking), harsh discipline at all stages of childhood carries a large risk of manifesting antisocial 'externalising behaviours' in the child, including aggression, delinquency or hyperactivity.

Study shows long-term exposure to fine particle matter air pollution is associated with atherosclerosis

The association between road traffic and heart disease has been suggested in several studies. In 2012 a large prospective cohort study from Denmark showed that traffic noise was significantly associated with risk of heart attack - for every 10 decibel increase in noise exposure (either at the time of the attack or over the five years preceding it) there was a 12% increased risk.

Mentally vulnerable people face increase risk of fatal and non-fatal cardiovascular disease

People deemed to be "mentally vulnerable" are at a significantly increased risk of both fatal and non-fatal cardiovascular disease, according to results of a large population study from Denmark. The details of the study were presented today at the EuroPRevent 2013 congress in Rome.

Studies suggest physically demanding work is a risk factor for coronary heart disease

Two studies presented at this year's EuroPRevent 2013 congress suggest that demanding physical work has a detrimental effect on an individual's risk of coronary heart disease.

New combination therapies with anti-sickling capabilities needed for sickle cell disease

Pain is an undeniable focal point for patients with sickle cell disease but it's not the best focus for drug development, says one of the dying breed of physicians specializing in the condition.
