Placental function can illuminate future disease in adults and children

AURORA, Colo. (Jan. 22, 2021) – Researchers at the University of Colorado Anschutz Medical Campus have discovered a direct association between placental function in pregnant women and future metabolic disorders in children and adults, a finding that could lead to earlier intervention and diagnosis of disease. “We’ve known for some time that many major diseases […]

How did forelimb function change as vertebrates acquired limbs and moved onto land?

When tetrapods (four-limbed vertebrates) began to move from water to land roughly 390 million years ago it set in motion the rise of lizards, birds, mammals, and all land animals that exist today, including humans […]

New treatment allows some people with spinal cord injury to regain hand and arm function

Almost 18,000 Americans experience traumatic spinal cord injuries every year. Many of these people are unable to use their hands and arms and can’t do everyday tasks such as eating, grooming or drinking water without help. Using physical therapy combined with a noninvasive method of stimulating nerve cells in the spinal cord, University of Washington […]

Tweaking AI software to function like a human brain improves computer’s learning ability

WASHINGTON – Computer-based artificial intelligence can function more like human intelligence when programmed to use a much faster technique for learning new objects, say two neuroscientists who designed such a model that was designed to mirror human visual learning. In the journal Frontiers in Computational Neuroscience, Maximilian Riesenhuber, PhD, professor of neuroscience, at Georgetown University […]

Gut microbiota plays a role in brain function and mood regulation — ScienceDaily

Depression is a mental disorder that affects more than 264 million people of all ages worldwide. Understanding its mechanisms is vital for the development of effective therapeutic strategies. Scientists from the Institut Pasteur, Inserm and the CNRS recently conducted a study showing that an imbalance in the gut bacterial community can cause a reduction in […]

Study forecasts advantages and disadvantages for Black patients of removing race from kidney function calculators — ScienceDaily

Race is not biology. As a social construct, race is an unreliable predictor of physiologic variation and a notoriously unreliable marker for biologic differences across populations. To reflect this growing realization, hospital systems and professional medical organizations have started reconsidering the use of race in clinical calculators that estimate how well a person’s kidneys work. […]

Methotrexate improves function in people with knee OA after 3 months

ATLANTA — A new study presented at ACR Convergence, the American College of Rheumatology’s annual meeting, shows that after three months of treatment with oral methotrexate, adults with primary knee osteoarthritis (OA) with inflammation had significant improvements in physical function and inflammation, a sign that this inexpensive, generic pill may be an important intervention for […]

Natural killer cells also have a memory function
