Medical Xpress / Bacterial supplements may boost female fertility
As women get older, their uterine environment changes. This includes a decrease in a beneficial bacterium called Lactobacillus gasseri, which may make conception—whether natural or via in vitro fertilization—difficult. In ...
Medical Xpress / Map of tonsil's genetic 'spaghetti' yields insights into immunity
About 2 meters (6.6 feet) of genetic material must fit into the nucleus of each of most of our trillions of cells, coiling and winding to form what looks like a tangled mess. But when genes are used, how they are used and ...
Medical Xpress / Mammography use has dropped among some groups, study finds
Researchers at WashU Medicine have found a significant decline in mammography use among certain groups of women. A recent study, led by Adetunji Toriola, MD, Ph.D., a professor of surgery and a William H. Danforth Washington ...
Medical Xpress / First complete marmoset genome will enable research on Alzheimer's and neurodegenerative diseases
To study complex diseases like Alzheimer's, scientists and clinicians analyze how genes change and malfunction in other species. Marmosets, a species of tiny monkey from South America, have become an important animal model ...
Medical Xpress / Gene mutations behind serious bone marrow conditions identified
Inherited bone marrow failure syndrome, or IBMFS, describes a group of disorders in which inherited genetic abnormalities impair the bone marrow's ability to produce sufficient healthy blood cells. Patients with these disorders ...
Medical Xpress / Immune-inspired public health strategy improves detection of disease-carrying insects
A disease surveillance strategy modeled on the body's immune system detected more disease-carrying insects than the traditional top-down approach, according to a study led by researchers from the Perelman School of Medicine ...
Medical Xpress / How oxygen levels synchronize heart muscle and blood vessel development
During development, regional dips in oxygen levels serve as a signal that triggers the coordinated growth of heart muscle and coronary vessels, according to a study led by researchers at Weill Cornell Medicine. The findings, ...
Medical Xpress / Wearable fingertip sensor identifies physical patterns linked to stress and anxiety
Researchers have shown that measurements taken from a person's fingertip could help identify physical patterns associated with stress, anxiety and depression. The international study, involving experts from Aston University, ...
Medical Xpress / Soluble signals released by neighboring cells direct how the human kidney is built
A human kidney is built once, before birth, and the rules guiding its construction have been largely inferred from animal models. Researchers at Penn Medicine have now read those rules directly in human tissue. They found ...
Medical Xpress / Three proteins help organs tailor shared circadian clock to their individual needs, mouse study finds
LMU researchers have elucidated how different organs adapt the same clock machinery to regulate their individual needs over the course of a day.
Medical Xpress / Hidden DNA regulators may drive neurodevelopmental disorders by reducing FOXG1 protein
A new study from the laboratory of Gemma Carvill, Ph.D., associate professor in the Ken and Ruth Davee Department of Neurology's Division of Epilepsy and Clinical Neurophysiology, has uncovered variants in noncoding regulatory ...
Medical Xpress / From planning to action: Fundamental insights on movement planning in the brain
When the signal sounds, all the runners push off from their starting blocks and set off sprinting. We can act within fractions of a second because we plan movements in our brains in advance, before carrying them out. At the ...
