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.
Researchers have identified a genomic variant strongly associated with sensitivity to the sun, brown hair, blue eyes – and freckles. In the study of Icelanders the researchers uncovered an intricate pathway involving the interspersed DNA sequence, or non-coding region, of a gene that is among a few dozen that are associated with human pigmentation traits.
Adult patients with a type of cancer known as Burkitt lymphoma had excellent long-term survival rates — upwards of 90 percent — following treatment with low-intensity chemotherapy regimens, according to a new clinical trial finding. Standard treatment for Burkitt lymphoma involves high-dose chemotherapy, which has a high rate of toxicity, including death, and cures only 60 percent of adult patients. This trial was conducted by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and appeared Nov. 14, 2013, in the New England Journal of Medicine.
Researchers have launched an early-stage clinical trial of an investigational vaccine designed to prevent genital herpes disease. The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, is sponsoring the Phase I trial, which is being conducted at the NIH Clinical Center in Bethesda, Md.
Structure-based design may be key to successful vaccine for common childhood illness
An experimental vaccine to protect against respiratory syncytial virus (RSV), a leading cause of illness and hospitalization among very young children, elicited high levels of RSV-specific antibodies when tested in animals, according to a report in the journal Science.
Three scientists at the National Institutes of Health have been elected members of the Institute of Medicine. Election to the IOM is considered one of the highest honors in the fields of health and medicine and recognizes individuals who have demonstrated outstanding professional achievement and commitment to service.
A gene important in skin tanning has been linked to higher risk for testicular cancer in white men, according to a study led by scientists from the U.S. National Institutes of Health and the University of Oxford in England. Nearly 80 percent of white men carry a variant form of this gene, which increased risk of testicular cancer up to threefold in the study.
Mouse study suggests new drug could slow progress of fatal childhood disorder
Researchers at the National Institutes of Health have identified a potential new drug that could help in the treatment of a form of Batten disease, a fatal childhood disorder. The researchers tested the drug in mice with the disease and found that it slowed the loss of coordination seen in the disorder, and extended the animals’ life span.
Selectively bred strains of laboratory rats that either prefer or avoid alcohol have been a mainstay of alcohol research for decades. So-called alcohol-preferring rats voluntarily consume much greater amounts of alcohol than do non-preferring rats. Scientists at the National Institutes of Health now report that a specific gene plays an important role in the alcohol-consuming tendencies of both types of rats.
Scientists from NIH and Australia investigate risk factors that contribute to cerebral palsy and early infant death
Karin B. Nelson, M.D., scientist emeritus at the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health, and her colleagues from the University of Sydney, the University of Western Australia and Sydney Adventist Hospital in Australia examined the degree to which four specific risk factors contributed to cerebral palsy and young infant death. The risk factors were asphyxial birth events (incidences during labor and delivery that had the potential to interfere with oxygen getting to the newborn’s brain), inflammation (signs of infection), birth defects, and poor fetal growth (low birth weight plus some other factors related to expected size).
NIH intramural study also shows that individual organs are affected differently
By lowering the expression of a single gene, researchers at the National Institutes of Health have extended the average lifespan of a group of mice by about 20 percent — the equivalent of raising the average human lifespan by 16 years, from 79 to 95. The research team targeted a gene called mTOR, which is involved in metabolism and energy balance, and may be connected with the increased lifespan associated with caloric restriction.
