For persons aged 60 years or older with displaced distal radius fracture, surgical treatment seems not to be better than nonsurgical treatment for patient-reported wrist function, according to a study published online April 27 in JAMA Surgery. Andrew Lawson, M.P.H., from the Ingham Institute for Applied Medical Research in Sydney, and colleagues conducted a secondary analysis...
How one inflammatory disorder exacerbates another
by Katherine Unger Baillie, University of Pennsylvania Inflammation in the gums can increase susceptibility to other forms of inflammation, such as arthritis, through changes to immune cell precursors in the bone marrow, according to new research led by Penn scientists and collaborators. Credit: Katie Vicari The immune system remembers. Often this memory, primed by past...
‘Keto’ molecule may be useful in preventing and treating colorectal cancer, study suggests
by Perelman School of Medicine at the University of Pennsylvania Cancer — Histopathologic image of colonic carcinoid. Credit: Wikipedia/CC BY-SA 3.0 A molecule produced in the liver in response to low-carb “ketogenic” diets has a powerful effect in suppressing colorectal tumor growth and may be useful as a preventive and treatment of such cancers, according...
How it works: The protein that stimulates muscle growth
by Laurie Fickman, University of Houston Credit: CC0 Public Domain In the gym, you are not just pumping iron, you are oxygenating muscle cells which keeps those muscles healthy, strong and growing—a process called hypertrophy, or an increase in muscle mass due to an increase in muscle cell size. Conversely, under the covers, lounging, your...
Virtual Reality in Neurorehabilitation
By Dmitry Dorofeev, B.Sc Reviewed by Sophia Coveney What is virtual reality? Virtual reality is an environment generated with the help of animated computer programs and displayed on the screen – an external space that is similar to a real one. Although it has similar properties to film and television, virtual reality has some distinctive...
RACE SKEWS EXPERIMENTAL ALZHEIMER’S BLOOD TEST RESULTS
A fourth blood test, the PrecivityAD test, is equally effective at detecting early Alzheimer’s disease regardless of the race of the person being tested, the researchers say. Since cutoffs between normal and abnormal test scores usually are set based on predominantly white volunteers, tests that perform differently in Black compared to white populations put Black...
University of Washington COVID vaccine effective in test
A COVID-19 vaccine developed at the University of Washington School of Medicine has proven safe and effective in late-stage clinical testing. SK bioscience, the company leading the vaccine’s clinical development, will seek authorization for its use in South Korea within the month. The Seattle scientists behind the new vaccine sought to create a ‘second-generation’ vaccine for COVID-19...
How the Discovery of an Alzheimer’s Tipping Point Could Improve Drug Trials
Researchers have known for many years that Alzheimer’s disease involves two proteins called amyloid-beta and tau, and that interaction drives the spread of neurodegeneration. What hasn’t been clear is where and how those interactions occur over time as the disease progresses. In a study published in the journal Neuron, neurologist William Seeley, MD, and his colleagues at...
Molecular Robots Swarm to Deliver Cargo
APRIL 26TH, 2022 CONN HASTINGS MEDICINE, NANOMEDICINE, ONCOLOGY Researchers at Hokkaido University in Japan created molecular robots that can employ swarm behaviors to move and release small cargoes. The robots can be controlled using light, and they consist of biological components, including DNA, microtubules, which are a cytoskeletal component, and kinesin, which is a motor protein...
