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:
BETHESDA, Md. (AP) — Sam Srisatta, a 20-year-old Florida college student, spent a month living inside a government hospital here last fall, playing video games and allowing scientists to document every morsel of food that went into his mouth.
From big bowls of salad to platters of meatballs and spaghetti sauce, Srisatta noshed his way through a nutrition study aimed at understanding the health effects of ultraprocessed foods, the controversial fare that now accounts for more than 70% of the U.S. food supply. He allowed The Associated Press to tag along for a day.
“Today my lunch was chicken nuggets, some chips, some ketchup,” said Srisatta, one of three dozen participants paid $5,000 each to devote 28 days of their lives to science. “It was pretty fulfilling.”
Examining exactly what made those nuggets so satisfying is the goal of the widely anticipated research led by National Institutes of Health nutrition researcher Kevin Hall.
“What we hope to do is figure out what those mechanisms are so that we can better understand that process,” Hall said.
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.
Side effects minimized with combination therapy in hard-to-treat patients
In a study of an all-oral drug regimen, a majority of volunteers with liver damage due to hepatitis C virus (HCV) infection were cured following a six-month course of therapy that combined an experimental drug, sofosbuvir, with the licensed antiviral drug ribavirin. The results showed that the regimen was highly effective in clearing the virus and well tolerated in a group of patients who historically have had unfavorable prognoses. Scientists from the National Institute of Allergy and Infectious Diseases (NIAID) and the NIH Clinical Center, parts of the National Institutes of Health, led the Phase II trial.
Chronic alcohol exposure leads to brain adaptations that shift behavior control away from an area of the brain involved in complex decision-making and toward a region associated with habit formation, according to a new study conducted in mice by scientists at the National Institutes of Health.
