For most women, expecting a baby brings intense joy -- and a fair amount of worry. But what about women who have lived through something awful enough to cause post-traumatic stress disorder? Contrary to what researchers expected, a new study shows that pregnancy may actually reduce their PTSD symptoms. Or at the least, it won't cause a flare-up.
Recently, a new mutation signature found in cancer cells was suspected to have been created by a family of enzymes found in human cells called the APOBEC3 family. The study, 'Strand-biased Cytosine deamination at the Replication Fork causes Cytosine to Thymine Mutations in Escherichia coli,' led by Ashok Bhagwat, Ph.D., professor of chemistry in the College of Liberal Arts and Sciences at Wayne State University, was recently published in the Proceedings of the National Academy of Sciences.
A McGill-led research team has recently discovered that for girls who are carriers of a particular gene variant (DRD4 VNTR with 7 repeats), the crucial element that influences a child's fat intake is not the gene variant itself. Instead, it is the interplay between the gene and girls' early socioeconomic environment that may determine whether they have increased fat intake or healthier than average eating compared to their peers from the same class background.
Differences in the neural wiring across development of men and women across ages, matched behavioral differences commonly associated with each of the sexes, according to an imaging-based study from researchers at the Perelman School of Medicine at the University of Pennsylvania published Feb. 1 in Philosophical Transactions of the Royal Society B.
A USC-led team of researchers have hope that behavioral interventions could help doctors slow the rise of treatment-resistant infections in hospitals and clinics, reduce adverse drug events in patients, and lower health care costs.
Infant girls at risk for autism pay more attention to social cues in faces than infant boys, according to a Yale School of Medicine study -- the first one known to prospectively examine sex-related social differences in at-risk infants.
A team at Cold Spring Harbor Laboratory has discovered the purpose of a highly conserved genetic tool that is present in both mosses and flowering plants, organisms whose common ancestor dates back 450 million years. As they report in Developmental Cell, the gene network, which comprising a snippet of non-coding genetic material called a small RNA and the protein it regulates, has been used over the eons to make plants more sensitive to environmental cues and facilitate robust, yet flexible, responses to those cues.
In injured mouse intestines, specific types of bacteria step forward to promote healing, Emory scientists have found. Potentially, some of these microbes could be exploited as treatments for conditions such as inflammatory bowel disease.
Researchers from Carnegie Mellon University have created the first robotically driven experimentation system to determine the effects of a large number of drugs on many proteins, reducing the number of necessary experiments by 70 percent.
A new way of mapping the collection of RNA read-outs that are expressed by a cell's active genes has been devised to shed additional light on the role of RNAs in cells. These 'dark' variations in RNA likely have roles in gene regulation across tissues, development, and in human diseases. The team will use the now-free software to interrogate cells in brain disorders, cancers, and other illnesses.
