In multiple sclerosis, a defective response of the body's own immune system leads to brain tissue damage. Gastrointestinal microbiota could play a far greater role in the pathogenesis of the disease than previously assumed, researchers at the University of Zurich have now found.
Becoming overweight at a young age can trigger a molecular chain reaction that leads some girls to experience puberty early, according to new research published in Nature Communications. Scientists have discovered an enzyme in the brain that behaves differently in fat and thin rats, and leads overweight female rats to have early-onset puberty.
One amino acid, alanine, may produce a short-term lowering of glucose levels by altering energy metabolism in the cell.
For those living with diabetes, monitoring blood glucose accurately is necessary to prevent diabetes-related complications. Researchers from the University of Missouri School of Medicine and the Massachusetts Institute of Technology recently evaluated the accuracy of an MIT-developed technology to monitor blood glucose levels without needles or a finger prick. Early results show that the noninvasive technology measures blood glucose levels as effectively as a finger prick test -- without drawing blood.
Microablative fractional CO2 lasers are energy-based devices designed to help manage troublesome menopause symptoms such as painful sex, dryness, itching/burning, urinary frequency, and incontinence. Although there is ongoing debate regarding the safety and effectiveness of vaginal laser surgery, a new study suggests that it may be effective, especially after multiple treatments. Study results are published online in Menopause, the journal of The North American Menopause Society (NAMS).
Planned intermittent fasting may help to reverse type 2 diabetes, suggest doctors writing in the journal BMJ Case Reports after three patients in their care, who did this, were able to cut out the need for insulin treatment altogether.
Consuming too much vitamin A may decrease bone thickness, leading to weak and fracture prone bones, according to a study published in the Journal of Endocrinology. The study, undertaken in mice, found that sustained intake of vitamin A, at levels equivalent to 4.5-13 times the human recommended daily allowance (RDA), caused significant weakening of the bones, and suggests that people should be cautious of over-supplementing vitamin A in their diets.
While liver biopsies are powerful and reliable, they are also invasive, painful, limited and subject to complications. These effects may soon be a thing of the past for some patients thanks to new research showing PET imaging with the 18F-FAC radiotracer can be used as a non-invasive substitute. The study is featured in the October issue of The Journal of Nuclear Medicine.
A discovery by scientists at UC Riverside may open up new ways to control steroid hormone-mediated processes, including growth and development in insects, and sexual maturation, immunity, and cancer progression in humans.
Study is the largest meta-analysis to date and includes data from 81 randomized controlled trials.
