Researchers find benefits and drawbacks to two-step surgical approach for ‘leaky heart valves’: Study finds better short-term outcomes, but increased need for a pacemaker
Patients with mitral and tricuspid valve regurgitation, a condition sometimes called “leaky heart valves,” appeared to do better after two years if they had a tricuspid valve repair at the time of mitral valve surgery, according to a study supported by the National Heart, Lung, and Blood Institute (NHLBI), a part of the National Institutes […]
Supplements to Prevent Bone Breaks? VITAL Says Forget It
New analyses from the big prospective study called VITAL cast additional doubt on the value of routine vitamin D and omega-3 fatty acid supplements for generally healthy individuals. Daily administration of 2,000 IU of vitamin D, in many cases on top of supplements that study participants were taking on their own, had no effect on […]
Are Rubella and German Measles the Same? Rubella vs Measles Chart
Rubella is a contagious viral infection that is also called German measles or three-day measles. While rubella infection symptoms are mild, they are more severe for pregnant women. Rubella, commonly called German measles or three-day measles, is usually a mild illness caused by a virus. While it is also called German measles the virus that […]
Yeast and bacteria together biosynthesize plant hormones for weed control: Synthetic strigolactones could also improve nutrient uptake in crops
Plants regulate their growth and development using hormones, including a group called strigolactones that prevent excessive budding and branching. For the first time, scientists led by UC Riverside have synthesized strigolactones from microbes. The work is published in the open-access journal, Science Advances. Strigolactones also help plant roots form symbiotic relationships with microorganisms that allow […]
Jaws; or, how an African ray-finned fish is helping to rethink the fundamentals of evolution: New research suggests that some evolutionary constraints are the secret to success
A family of fishes, called the cichlids, in Africa’s Lake Malawi is helping researchers at the University of Massachusetts Amherst to refine our understanding of how evolution works. In new research published in Nature Communications, co-authors Andrew J. Conith, postdoctoral researcher in the UMass Amherst biology department, and Craig Albertson, professor of biology at UMass […]
WHO Seeks Booster Shot Moratorium So Other Countries Can Catch Up
GENEVA (AP) — The head of the World Health Organization called Wednesday for a moratorium on administering booster shots of COVID-19 vaccines as a way to help ensure that doses are available in countries where few people have received their first shots. WHO Director-General Tedros Adhanom Ghebreyesus made the appeal mostly to wealthier countries that […]
Managing attention deficit disorder by training the brain
Scientists explored a technique called ‘neurofeedback,’ which enables ADHD patients to train their attention, based on instant feedback from the level of their brain activity. The team of neuroscientists found that not only did the training have a positive effect on patients’ concentration abilities, but also that the attention improvement was closely linked to an […]
