NIH researchers have discovered molecular mechanisms that may underlie a woman’s susceptibility to disabling irritability, sadness and anxiety in the days leading up to her menstrual period.

Investigators with the Cancer Genome Atlas (TCGA) Research Network have identified novel genomic and molecular characteristics of cervical cancer that will aid in the sub-classification of the disease and may help target therapies that are most appropriate for each patient.

Children of obese parents may be at risk for developmental delays, according to a study by researchers at NIH.

An investigational malaria vaccine has protected a small number of healthy U.S. adults from infection with a malaria strain different from that contained in the vaccine, according to a study published Feb. 21 in the Proceedings of the National Academy of Sciences.

Very early preterm infants are more likely to survive than in previous years and the survivors are less likely to have neurological problems, according to an analysis of records from an NIH research network.

In older men with low testosterone, 1 year of testosterone treatment improved bone density and corrected anemia of both known and unknown causes, but also increased the volume of coronary artery plaque, according to results reported from the Testosterone Trials (T Trials).

Researchers at Vanderbilt University have discovered that in zebrafish, decreased levels of the neurotransmitter gamma-aminobutyric acid (GABA) cue the retina, the light-sensing tissue in the back of the eye, to produce stem cells.

An international team of researchers has discovered that approximately 1 percent of West Africans, African Americans and others of African ancestry carry a genomic variant that increases their risk of obesity.

A study in Neurology suggests that analyzing levels of the protein p75ECD in urine samples from people with amyotrophic lateral sclerosis (ALS) may help monitor disease progression as well as determine the effectiveness of therapies.

A study in mice and humans suggests that bacteria in the gut can influence the structure of the brain’s blood vessels and may be responsible for producing malformations that can lead to stroke or epilepsy.
