A new study warns, even one night of lost sleep may cause the brain to fill with protein chunks that have long been linked to the development of Alzheimer's disease
Researchers developed a camera that concentrated beneath the skin to help diagnose and monitor a wide variety of health conditions. The interdisciplinary effort, led by Rice University, will combine advanced optics and sophisticated computation to make sense of light that penetrates the skin but scatters off internal tissues and anatomical structures. This will enable noninvasive bio-optical imaging at a cellular scale something not possible with ultrasound, X-rays and other medical imaging technologies.
Clitoral reconstruction after female genital mutilation is associated with improved sexual function and genital self-image, clinicians from Spain report. It has emerged as an effective way to restore genitals and improve quality of life.
By mimicking the intricate visual system of a butterfly, researchers have created a camera that provides surgeons with both a traditional color image as well as a near-infrared image that makes fluorescently labeled cancerous cells visible even under bright surgical lighting.
The new camera is designed to help surgeons remove all the cancerous cells without damaging healthy tissue, making it less likely that cancer will spread and reducing the need for multiple surgeries.
Researchers from Johns Hopkins University may have found an alternative use for metformin – a common diabetes drug. In a study conducted on mice, it was showed that metformin potentially blocks symptoms of nicotine withdrawal in rodents. The study findings, reported in the Proceedings of the National Academy of Sciences (PNAS), could help people to kick their nicotine habits.
A new study established a novel technique that prevents coronary artery obstruction during transcatheter aortic valve replacement (TAVR), a rare but often fatal complication. The method, called Bioprosthetic Aortic Scallop Intentional Laceration to prevent Iatrogenic Coronary Artery obstruction (BASILICA), will increase treatment options for high-risk patients who need heart valve procedures. The study was published in the Journal of the American College of Cardiology: Cardiovascular Interventions.
Researchers have developed a new approach to repair cells deep inside the ear, a potential remedy that could restore hearing for millions of elderly people and others who suffer hearing loss. The lab study demonstrates a novel way for a drug to zero in on damaged nerves and cells inside the ear. It's a potential remedy for a problem that afflicts two-thirds of people over 70 years and 17% of all adults in the United States.
Researchers established the discovery of a new class of antibiotics that may be effective in treating drug-resistant infections. A newly discovered antibiotic binds to the ribosome for disrupting protein synthesis. Researchers from the University of Illinois at Chicago and Nosopharm, a biotechnology company based in Lyon, France, are part of an international team reporting on the discovery of a new class of antibiotics. The study was published in Molecular Cell.
In Tennessee, treatment for veterans is beginning to include the ancient martial art of tai chi. Zibin Guo guides veterans in wheelchairs through slow-motion poses as a Bluetooth speaker blares a classic tai chi soundtrack. The practice of tai chi could help ease pain and PTSD, according to Guo.
Researchers at the University of Georgia have discovered that dormancy of the parasite Trypanosoma cruzi prevents effective drug treatment for Chagas disease, which kills more than 50,000 people each year in Central and South America and is a growing threat in the United States and Europe.
NEW YORK (Reuters Health) – Variation in the use of exclusive enteral nutrition (EEN) for pediatric Crohn's disease highlights the need to improve patient education and support and reduce barriers to treatment, researchers say.
