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:
Whether you’re shedding pounds with the help of effective new medicines, slimming down after weight loss surgery or cutting calories and adding exercise, there will come a day when the numbers on the scale stop going down, and you hit the dreaded weight loss plateau.
In a recent study, Kevin Hall, a researcher at the National Institutes of Health who specializes in measuring metabolism and weight change, looked at when weight loss typically stops depending on the method people were using todrop pounds. He broke down the plateau into mathematical models using data from high-quality clinical trials of different ways to lose weight to understand why people stop losing when they do. The study published Monday in the journal Obesity.
Gene therapy can be performed safely in the human salivary gland, according to scientists at the National Institute of Dental and Craniofacial Research (NIDCR), part of the National Institutes of Health. This finding comes from the first-ever safety, or Phase I, clinical study of gene therapy in a human salivary gland. Its results, published this week in the Proceedings of the National Academy of Sciences, also show that the transferred gene, Aquaporin-1, has great potential to help head and neck cancer survivors who battle with chronic dry mouth.
National Institutes of Health (NIH) researchers have discovered a significant new mechanism of action for a class of chemotherapy drugs known as poly (ADP-ribose) polymerase inhibitors, or PARP inhibitors. They have also identified differences in the toxic capabilities of three drugs in this class which are currently being tested in clinical trials.
The world's largest, most detailed catalog of human genetic variation — used by disease researchers around the world — has more than doubled in size with the 1000 Genomes Project's latest publication in the Oct. 31 issue of Nature. The National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, helps fund and direct this international public-private consortium of researchers in the United States, Britain, China, Germany and Canada.
Serous endometrial tumors account for some of the most difficult to treat cancers of the uterine lining
Researchers have identified several genes that are linked to one of the most lethal forms of uterine cancer, serous endometrial cancer. The researchers describe how three of the genes found in the study are frequently altered in the disease, suggesting that the genes drive the development of tumors.
NIH research shows exercise as key in reducing body fat while preserving muscle
Exercise and healthy eating reduce body fat and preserve muscle in adults better than diet alone, according to a study funded and conducted by National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), part of the National Institutes of Health.
A bacterial protein in common house dust may worsen allergic responses to indoor allergens, according to research conducted by the National Institutes of Health and Duke University. The finding is the first to document the presence of the protein flagellin in house dust, bolstering the link between allergic asthma and the environment.
Andrew Holmes, Ph.D., chief of the Laboratory of Behavioral and Genomic Neuroscience at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health, has been selected as the 2012 recipient of the Jacob P. Waletzky Award from the Society for Neuroscience. The $25,000 prize is given in recognition of innovative research into substance abuse and the brain and nervous system.
A free source of evidence-based information for health care professionals and for researchers studying liver injury associated with prescription and over-the-counter drugs, herbals, and dietary supplements is now available from the National Institutes of Health. Researchers and health care professionals can use the LiverTox database to identify basic and clinical research questions to be answered and to chart optimal ways to diagnose and control drug-induced liver injury.
Results may help improve drugs for neurological disorders
Researchers have published the first highly detailed description of how neurotensin, a neuropeptide hormone which modulates nerve cell activity in the brain, interacts with its receptor. Their results suggest that neuropeptide hormones use a novel binding mechanism to activate a class of receptors called G-protein coupled receptors (GPCRs).
NIH-supported study first to show reduced risk solely through dietary modification
By sticking to a healthy diet in the years after pregnancy, women who develop diabetes during pregnancy can greatly reduce their risk of developing type 2 diabetes, a study supported by the National Institutes of Health has found.
