Mayo Clinic Study Shows Association Among Childhood ADHD, Sex And Obesity,
A new study has found the brain’s information storage capacity may be around a quadrillion bytes,
The National Institutes of Health today announced its research priorities for studies to investigate how Zika virus infection affects reproduction, pregnancy and the developing fetus. Zika virus currently is circulating in about 30 countries and territories (link is external), notably in Latin America and the Caribbean. The virus has been linked to a spike in cases of microcephaly (link is external)— an abnormally small head resulting from an underdeveloped and/or damaged brain — among newborn babies.
National Institutes of Health researchers have identified a striking signature in tumor DNA that occurs in five different types of cancer. They also found evidence that this methylation signature may be present in many more types of cancer. The specific signature results from a chemical modification of DNA called methylation, which can control the expression of genes like a dimmer on a light switch. Higher amounts of DNA methylation (hypermethylation), like that found by the researchers in some tumor DNA, decreases a gene’s activity. Based on this advance, the researchers hope to spur development of a blood test that can be used to diagnose a variety of cancers at early stages, when treatments can be most effective. The study appeared Feb. 5, 2016, in The Journal of Molecular Diagnostics.
Vacations Can Lead To Weight Gain, Contribute To ‘Creeping Obesity’
Prenatal steroid therapy reduces the chance of respiratory complications among infants born at 34-36 weeks, so-called “late” preterm infants, according to a study by a National Institutes of Health research network.
Scientists at the National Institutes of Health have identified a genetic mutation responsible for a rare form of inherited hives induced by vibration, also known as vibratory urticaria. Running, hand clapping, towel drying or even taking a bumpy bus ride can cause temporary skin rashes in people with this rare disorder. By studying affected families, researchers discovered how vibration promotes the release of inflammatory chemicals from the immune system’s mast cells, causing hives and other allergic symptoms.
Depression can be a devastating and unremitting problem,
Researchers of a new study published in the current issue of Biological Psychiatry report successful reduction of depressive symptoms in patients using a novel non-invasive method of vagus nerve stimulation, or VNS.
Scientists at the University of Georgia have shown that a hormone instrumental in the aging process is under genetic control, introducing a new pathway by which genetics regulates aging and disease.
Increasing the level of a naturally-produced protein, called tristetraprolin (TTP), significantly reduced or protected mice from inflammation, according to researchers at the National Institutes of Health. The results suggest that pharmaceutical compounds or other therapeutic methods that produce elevated levels of TTP in humans may offer an effective treatment for some inflammatory diseases, such as rheumatoid arthritis, psoriasis, and multiple sclerosis. The report appeared online Feb. 1 in the Proceedings of the National Academy of Sciences.
