A cooling technique intended to protect the skin may actually increase the risk of discoloration in dark-skinned patients undergoing laser treatments for mole-like skin lesions, according to a report in the September issue of Archives of Dermatology, one of the JAMA/Archives journals.
A groundbreaking environmental study to be published in a prestigious American science journal proves that mercury atmospheric emissions will end up in fish in as little as three years. Biologists from the University of Alberta in Edmonton, Canada, played a key role in designing and carrying out the experiment.
The 15 minutes it took to remove Buffalo Bills player Kevin Everett off the field after he suffered a spinal cord injury may seem like a long time for someone needing acute medical care, but in fact, those minutes underscore how critical it is to carefully move a player with a suspected spinal cord injury off the field. It also highlights the challenges faced when needing to minimize any further movement to an injured spinal cord.
The most commonly used measure for pain screening may only be modestly accurate, according to researchers from the Indiana University School of Medicine and the University of North Carolina. In a study that appears in the October issue of the Journal of General Internal Medicine, they evaluate the usefulness of a scale that asks patients in primary care to rate their current pain from 0 (no pain) to 10 (worst pain).
Women and men appear to respond differently to the same biochemical manipulation. Major depressive disorder (MDD) is one of the most common mental disorders, and it is also one of the most studied.
For orthopaedic implants to be successful, bone must meld to the metal that these artificial hips, knees and shoulders are made of. A team of Brown University engineers, led by Thomas Webster, has discovered a new material that could significantly increase this success rate.
A team of researchers led by Fei Hu, assistant professor of computer engineering at Rochester Institute of Technology, is working to advance the integration of radio frequency identification technology, also known as RFID, into cardiac sensor networks, a new wireless technology for telemedicine delivery.
A preliminary study suggests that patients with cancer in the head and neck region may have inferior performance in some driving skills compared with individuals without the disease, according to a report in the September issue of Archives of Otolaryngology-Head & Neck Surgery, one of the JAMA/Archives journals.
For the first time scientists have been able to film, in real time, the nanoscale interaction of an enzyme and a DNA strand from an attacking virus. Researchers from the University of Cambridge have used a revolutionary Scanning Atomic Force Microscope in Japan to produce amazing footage of a protective enzyme unravelling the DNA of a virus trying to infect a bacterial host.
A University of Minnesota study of prostate cancer tumors from Caucasian and African-American men has shown no evidence that the cancer is more aggressive in black men. Lead investigator Akhouri Sinha, a professor of genetics, cell biology, and development and research scientist at the Minneapolis VA Medical Center, said the belief that black men’s tumors are more aggressive is based on studies that failed to match patients properly and used only indirect means to measure tumor aggressiveness.
