Inside the government study trying to understand the health effects of ultraprocessed foods

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.

New test offers more information on genetic causes of stillbirth

NIH network study confirms more detailed information from microarray analysis

A more precise method for examining a fetus’ genetic material may help detect abnormalities in 40 percent more cases of stillbirth than does the traditional method, according to a National Institutes of Health network study.

New rheumatoid arthritis drug targets NIH-discovered protein

The U.S. Food and Drug Administration recently approved a new oral medication for the treatment of rheumatoid arthritis that represents a new class of drugs for the disease... Tofacitinib is from a new class of drugs developed to target Janus kinases. One member of this family, JAK3, was discovered in the early 1990s by a National Institutes of Health laboratory in the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS).

Prenatal intervention reduces learning deficit in mice

Mice with a condition that serves as a laboratory model for Down syndrome perform better on memory and learning tasks as adults if they were treated before birth with neuroprotective peptides, according to researchers at the National Institutes of Health.

NIH study suggests immune system could play a central role in AMD

Changes in how genes in the immune system function may result in age-related macular degeneration (AMD), the leading cause of visual impairment in older adults, based on preliminary research conducted by National Institutes of Health (NIH) investigators.

This is your brain on freestyle rap

...The findings, published online in the Nov. 15 issue of the journal Scientific Reports, reveal that this form of vocal improvisation is associated with a unique functional reallocation of brain activity in the prefrontal cortex and proposes a novel neural network that appears to be intimately involved in improvisatory and creative endeavors.

PCBs, other pollutants may play role in pregnancy delay

Couples with high levels of PCBs and similar environmental pollutants take longer to achieve pregnancy in comparison to other couples with lower levels of the pollutants, according to a preliminary study by researchers at the National Institutes of Health and other institutions.

Gene variations linked to lung cancer susceptibility in Asian women

An international group of scientists has identified three genetic regions that predispose Asian women who have never smoked to lung cancer. The finding provides further evidence that risk of lung cancer among never-smokers, especially Asian women, may be associated with certain unique inherited genetic characteristics that distinguishes it from lung cancer in smokers.

First gene therapy study in human salivary gland shows promise

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.

NIH study uncovers new mechanism of action for class of chemotherapy drugs

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.
