Research advances from the National Institutes of Health (NIH) Intramural Research Program (IRP) often make headlines. Read the news releases that describe our most recent findings:
An immune system protein normally found in semen appears to enhance the spread of HIV to tissue from the uterine cervix, according to researchers at the National Institutes of Health.
NIH-funded consortium finds connection between lipoprotein(a) and valve calcification
A newly identified genetic variant doubles the risk of calcium buildup in the heart’s aortic valve. Calcium buildup is the most common cause of aortic stenosis, a narrowing of the aortic valve that can lead to heart failure, stroke, and sudden cardiac death.
A protein associated with conditions of metabolic imbalance, such as diabetes and obesity, may play a role in the development of aggressive forms of breast cancer, according to new findings by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and their colleagues. Metabolic imbalance is often caused by elevated carbohydrate intake, which can lead to over-activating a molecule called C-terminal binding protein (CtBP). This over-activation, in turn, can increase the risk of breast cancer. Results of their work appeared in Nature Communications, Feb. 5, 2013.
Signals dysfunction in brain system targeted by scopolamine – NIH study
A telltale boost of activity at the back of the brain while processing emotional information predicted whether depressed patients would respond to an experimental rapid-acting antidepressant, a National Institutes of Health study has found.
Physicians often fail to ask high school-aged patients about alcohol use and to advise young people to reduce or stop drinking, according to a study led by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health.
A new computed tomography (CT) scanner substantially reduces potentially harmful radiation while still improving overall image quality. National Institutes of Health researchers, along with engineers at Toshiba Medical Systems, worked on the scanner. An analysis of data on 107 patients undergoing heart scans found that radiation exposure was reduced by as much as 95 percent compared to the range of current machines, while the resulting images showed less blurriness, reduced graininess, and greater visibility of fine details.
Voluntary movements involve the coordinated activation of two brain pathways that connect parts of deep brain structures called the basal ganglia, according to a study in mice by researchers at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health. The findings, which challenge the classical view of basal ganglia function, were published online in Nature on Jan. 23.
A clinical trial to evaluate a drug candidate called cyclodextrin as a possible treatment for Niemann-Pick disease type C1 (NPC), a rare and fatal genetic disease, will start today, researchers announced. Scientists from the NIH’s National Center for Advancing Translational Sciences (NCATS) and the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) will conduct the clinical trial at the NIH Clinical Center. Reaching this trial stage required collaboration among government, industry, patient advocacy groups and academic researchers.
A candidate dengue vaccine developed by scientists at the National Institutes of Health has been found to be safe and to stimulate a strong immune response in most vaccine recipients, according to results from an early-stage clinical trial sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the NIH. The trial results appeared in the January 17 issue of the Journal of Infectious Diseases.
NIH researcher assists in study of Norwegian women
Norwegian pregnant women who received a vaccine against the 2009 H1N1 influenza virus showed no increased risk of pregnancy loss, while pregnant women who experienced influenza during pregnancy had an increased risk of miscarriages and still births, a study has found. The study suggests that influenza infection may increase the risk of fetal loss.
