Brain scan, AI may help determine efficacy of OCD treatment

Brain scan, AI may help determine efficacy of OCD treatment

Health
Feb. 14 (UPI) -- Researchers at the University of California Los Angeles have developed an artificial intelligence system to predict whether patients with obsessive compulsive disorder can benefit from cognitive behavior therapy.Neuroscience researchers at UCLA announced on Tuesday that a technique using brain scans and machine learning can forecast whether those with OCD should be treated with cognitive behavior therapy.OCD is a lifelong illness marked by repetitive thoughts and actions that can seriously impair work performance, relationships and quality of life. It is commonly treated with medication and cognitive behavioral therapy, or CBT, a form of psychotherapy. Treatment can be expensive and time-consuming, and is not always successful."If the results of this study are replicated i...

Study: Vitamin B3 variant could help Alzheimer's patients

Feb. 7 (UPI) -- A form of Vitamin B3 improved cognitive and physical function in mice with Alzheimer's disease-like symptoms in experiments, the National Institutes of Health report in a new study.The effects of the supplement nicotinamide riboside, a form of Vitamin B3, when given to mice suggests a new method for treating Alzheimer's disease, researchers at the National Institute on Aging, a NIH agency, reported on Tuesday.In Alzheimer's disease, the brain's usual DNA repair activity is impaired, leading to mitochondrial dysfunction, lower neuron production and increased neuronal dysfunction and inflammation. Nicotinamide riboside, or NR, normalizes levels of nicotinamide adenine dinucleotide, a metabolite vital to cellular energy, stem cell self-renewal, resistance to neuronal stress an...
Chemistry 'Van Gogh' could help with cancer

Chemistry 'Van Gogh' could help with cancer

Health
"Incredible" images of DNA in action have been captured by scientists who will use them to design cancer drugs.Researcher Dr Alessandro Vannini said the pictures were "beautiful" and in artistic comparisons were "definitely a Van Gogh". They capture a fundamental part of all plant and animal life, called RNA polymerase III, reading the genetic instructions contained in DNA.It is a process that gets hijacked by cancer. Human DNA contains the genetic instructions for building and running the human body. It is RNA polymerase III's job to come along and read the genetic instruction manual. The team at the Institute of Cancer Research used a technique called cryo-electron microscopy, which won the 2017 Nobel Prize for chemistry for revolutionising biochemistry. They purified RNA polymerase III,...
Study: Genetic indicators help determine COPD risk

Study: Genetic indicators help determine COPD risk

Health
Jan. 16 (UPI) -- Researchers found in study published Tuesday that genetic variations in lungs can help identify people at risk for chronic obstructive pulmonary disease, or COPD, which is often caused by cigarette smoke and pollution.The study -- funded by the National Heart, Lung and Blood Institute, which is part of the National Institutes of Health -- identified people with low, but stable, lung function early in life who developed COPD.For the study, published today in the Proceedings of the National Academy of Sciences, the scientists were attempting to learn why not all smokers develop COPD, but many non-smokers do."This work raises many interesting questions for researchers. Understanding precisely why these genes influence the development of COPD may lead to entirely new and more ...
Why this year's flu is worse and how to help prevent the spread

Why this year's flu is worse and how to help prevent the spread

Health
The flu has ramped up early this year and is rapidly spreading across the country, with widespread flu activity in 46 states, according to the latest data from the U.S. Centers for Disease Control and Prevention. "This is a feature of this year’s flu -- not only did it start early, but it seemed to occur all over the country more or less simultaneously," Dr. William Schaffner, infectious disease specialist at Vanderbilt University, told ABC News. The flu has not yet reached “epidemic” proportions, according to last week’s CDC data, but it may happen soon. A flu epidemic occurs when the percentage of people who have died from the flu exceeds a threshold set by the CDC using data from prior years. Last week, the number of people who died from the flu this year was only 0.2 percent below t
