Voice May Change After Rhinoplasty, Reports Plastic and Reconstructive Surgery

Patients who have undergone plastic surgery to change the appearance of their nose may also notice changes in the sound of their voice, reports a study in the February issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).

H.M.'s Brain Yields New Evidence

During his lifetime, Henry G. Molaison (H.M.) was the best-known and possibly the most-studied patient of modern neuroscience. Now, thanks to the postmortem study of his brain, based on histological sectioning and digital three-dimensional construction led by Jacopo Annese, PhD, at the University of California, San Diego, scientists around the globe will finally have insight into the neurological basis of the case that defined modern studies of human memory.

New Imaging Technique Speeds Removal of Non-Melanoma Skin Cancers

Skin cancer surgery involves successive removal of tissue, which is processed using a 45 minute procedure to determine if residual cancer remains and is often repeated several times. Now, NIBIB-funded researchers have developed a microscopic technique that identifies residual cancer tissue in 90 seconds, promising to dramatically reduce the length, inefficiency, and cost of this common surgery.

Melatonin Shows Potential to Slow Tumor Growth in Certain Breast Cancers

An early stage study shows melatonin – a hormone that regulates the body’s sleep and awake cycles – may have the potential to help slow the growth of certain breast cancer tumors, according to researchers from Henry Ford Hospital in Detroit and Foundation for Research Support of the State of São Paulo.

Converting Adult Human Cells to Hair-Follicle-Generating Stem Cells

Researchers have come up with a method to convert adult cells into epithelial stem cells, the first time anyone has achieved this in either humans or mice. The epithelial stem cells, when implanted into immunocompromised mice, regenerated the different cell types of human skin and hair follicles, and even produced structurally recognizable hair shaft, raising the possibility that they may eventually enable hair regeneration in people.

Université De Montréal Study Analyzes Content of Nightmares and Bad Dreams

According to a new study by researchers at the University of Montreal, nightmares have greater emotional impact than bad dreams do, and fear is not always a factor. In fact, it is mostly absent in bad dreams and in a third of nightmares.

Origins of Plague: Scientists Reveal the Cause of One of the Most Devastating Pandemics in Human History

A_JenniferKlunkexaminesasamplemedium.jpg

An international team of scientists has discovered that two of the world’s most devastating plagues – the plague of Justinian and the Black Death, each responsible for killing as many as half the people in Europe—were caused by distinct strains of the same pathogen, one that faded out on its own, the other leading to worldwide spread and re-emergence in the late 1800s. These findings suggest a new strain of plague could emerge again in humans in the future.

Research Finds Link Between Alcohol Use, Not Pot, and Domestic Violence

Research among college students found that men under the influence of alcohol are more likely to perpetrate physical, psychological or sexual aggression against their partners than men under the influence of marijuana. Women, on the other hand, were more likely to be physically and psychologically aggressive under the influence of alcohol but, unlike men, they were also more likely to be psychologically aggressive under the influence of marijuana.

Pesticide Exposure Linked to Alzheimer’s Disease

Scientists have known for more than 40 years that the synthetic pesticide DDT is harmful to bird habitats and a threat to the environment. Now researchers at Rutgers University, writing in JAMA Neurology, say exposure to DDT – banned in the United States since 1972 but still used as a pesticide in other countries – may also increase the risk and severity of Alzheimer’s disease in some people, particularly those over the age of 60.

Yoga Can Lower Fatigue, Inflammation in Breast Cancer Survivors

Practicing yoga for as little as three months can reduce fatigue and lower inflammation in breast cancer survivors, according to new research. The more the women in the study practiced yoga, the better their results.
