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 / 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 / Common blood storage bags may leach microplastics into stored blood
In the 1970s, PVC bags revolutionized the storage of blood and blood products for transfusion. Disposable plastic (PVC) bags replaced reusable glass bottles, making the process more convenient and safer from contamination. ...
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 / 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 / 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 ...
Medical Xpress / New vaccine strategy protects against chikungunya in mice and could become a platform for combating other diseases
An international team of researchers has developed an innovative strategy for producing new vaccines. They created a genetically modified version of the chikungunya virus that replicates only once yet still trains the immune ...
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 / Single dose of psilocybin for depression shows promising results in UK's first publicly funded randomized trial
The first randomized controlled trial in the U.K. has found that a single dose of psilocybin, the active compound found in "magic mushrooms," produced significant improvements in depression compared with a placebo. This is ...
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 / Rising deaths in LA County Jail are tied to longer stays, study shows
The effects of stress, depression and inadequate health care in the Los Angeles County Jail—a blanket term widely used for the county's eight facilities—build up into lethal risk, a new study led by UCLA researchers has found.
Medical Xpress / The human side of robotic surgery: Tracking surgeons' stress in the operating room
Robot-assisted surgery (RAS) is one of the most advanced tools in modern medicine. These systems give surgeons extreme precision, allowing procedures to be performed through small incisions that minimize both pain and recovery ...
