From bite site to brain: How rabies virus hijacks and speeds up transport in nerve cells

From bite site to brain: How rabies virus hijacks and speeds up transport in nerve cells

Rabies (and rabies virus, its causative agent) is usually transmitted through the bite of an infected animal into muscle tissue of the new host. From there, the virus travels all the way to the brain where it multiplies and causes the usually fatal disease. Continue reading

Small molecule acts as on-off switch for nature’s antibiotic factory: Tells Streptomyces to either veg out or get busy

Small molecule acts as on-off switch for nature’s antibiotic factory: Tells Streptomyces to either veg out or get busy

Scientists have identified the developmental on-off switch for Streptomyces, a group of soil microbes that produce more than two-thirds of the world’s naturally derived antibiotic medicines. Their hope now would be to see whether it is possible to manipulate this switch to make nature’s antibiotic factory more efficient. Continue reading

Indoor mold poses health risk to asthma sufferers

Indoor mold poses health risk to asthma sufferers

Damp and mould in homes could pose a significant health risk to people with asthma according to a new study published in the Journal of Allergy and Clinical Immunology. By critically reviewing the findings from 17 studies in eight different countries, the research has found that the presence of several types of mould can lead to breathing problems in asthma sufferers, as well as increasing the likelihood of developing the condition. The research has been conducted by a team at the University of Exeter Medical School and is the first time all of the information relating to mould and asthma has been gathered and analysed together.

Avatars make the Internet sign to deaf people

It is challenging for deaf people to learn a sound-based language, since they are physically not able to hear those sounds. Hence, most of them struggle with written language as well as with text reading and comprehension. Continue reading

Three-quarters of depressed cancer patients do not receive treatment for depression; new approach could transform care

Three-quarters of depressed cancer patients do not receive treatment for depression; new approach could transform care

Three papers published in The Lancet Psychiatry, The Lancet, and The Lancet Oncology reveal that around three-quarters of cancer patients who have major depression are not currently receiving treatment for depression, and that a new integrated treatment program is strikingly more effective at reducing depression and improving quality of life than current care. An analysis of data from more than 21,000 patients attending cancer clinics in Scotland, UK, published in The Lancet Psychiatry , found that major depression is substantially more common in cancer patients than in the general population Continue reading

Tracking spending among commercially insured

Tracking spending among commercially insured

Recent growth in health care spending for commercially insured individuals is due primarily to increases in prices for medical services, rather than increased use, according to a new study led by researchers at The Dartmouth Institute for Health Policy & Clinical Practice, published in the American Journal of Managed Care. There is increasing concern that consolidation in the health care marketplace will lead to increased prices faced by payers and, ultimately, consumers,” said Carrie Colla, PhD, assistant professor at The Dartmouth Institute and the study’s lead author Continue reading

Gang life brings deep health risks for girls

Gang life brings deep health risks for girls

Being involved in a gang poses considerable health-related risks for adolescent African American girls, including more casual sex partners and substance abuse combined with less testing for HIV and less knowledge about preventing sexually transmitted diseases, according to a new study.

Xenon exposure shown to erase traumatic memories

Xenon exposure shown to erase traumatic memories

McLean Hospital researchers are reporting that xenon gas, used in humans for anesthesia and diagnostic imaging, has the potential to be a treatment for post-traumatic stress disorder (PTSD) and other memory-related disorders. “In our study, we found that xenon gas has the capability of reducing memories of traumatic events,” said Edward G. Meloni, PhD, assistant psychologist at McLean Hospital and an assistant professor of Psychiatry at Harvard Medical School. Continue reading

Alcohol-dependence gene linked to neurotransmitter

Alcohol-dependence gene linked to neurotransmitter

Scientists at The Scripps Research Institute (TSRI) have solved the mystery of why a specific signaling pathway can be associated with alcohol dependence. This signaling pathway is regulated by a gene, called neurofibromatosis type 1 (Nf1), which TSRI scientists found is linked with excessive drinking in mice Continue reading
