Published Soccer heading linked to measurable decline in brain function (via sciencedaily.com)
New research links soccer heading -- where players hit the ball with their head -- to a measurable decline in the microstructure and function of the brain over a two-year period.
Published Eye-safe laser technology to diagnose traumatic brain injury (via sciencedaily.com)
Researchers have designed and developed a novel diagnostic device to detect traumatic brain injury (TBI) by shining a safe laser into the eye.
Published Researchers find connections between neuroinflammation and Alzheimer's disease (via sciencedaily.com)
Investigators revealed how genetic changes in certain types of brain cells may contribute to the inflammatory response seen in Alzheimer's disease.
Published Heart over head? Stages of the heart's cycle affect neural responses (via sciencedaily.com) Original source
Optimal windows exist for action and perception during the 0.8 seconds of a heartbeat, according to new research. The sequence of contraction and relaxation is linked to changes in the motor system and its ability to respond to stimulation, and this could have implications for treatments for depression and stroke that excite nerve cells.
Published Fat cells help repair damaged nerves (via sciencedaily.com) Original source
Damage to the body's peripheral nerves can cause pain and movement disorders. Researchers have recently investigated how damaged nerves can regenerate better. They found that fat tissue strongly supports the Schwann cells needed for repair during the healing process.
Published Repairing nerve cells after injury and in chronic disease (via sciencedaily.com) Original source
Researchers discovered a mechanism for repairing damaged nerves during peripheral neuropathy in mice, wherein the protein Mitf orchestrates nerve repair after both trauma-induced and chronic nerve damage conditions, like Charcot Marie Tooth disease. Their findings may inspire novel therapeutics that bolster repair function and heal peripheral neuropathy -- even in hereditary and developmental cases.
Published Discrimination during pregnancy can affect infant's brain circuitry (via sciencedaily.com) Original source
Experiences of discrimination and acculturation are known to have a detrimental effect on a person's health. For pregnant women, these painful experiences can also affect the brain circuitry of their children, a new study finds. These effects, the researchers say, are separate from those caused by general stress and depression. The study was published in the journal Neuropsychopharmacology.
Published Stronger thigh muscles may prevent knee replacement surgery (via sciencedaily.com) Original source
Stronger quadriceps muscles, relative to the hamstrings, may lower the risk of total knee replacement, according to new research. Researchers said the findings could inform strength-training programs for people with advanced arthritis in the knee.
Published New framework for using AI in health care considers medical knowledge, practices, procedures, values (via sciencedaily.com) Original source
Health care organizations are looking to artificial intelligence (AI) tools to improve patient care, but their translation into clinical settings has been inconsistent, in part because evaluating AI in health care remains challenging. In a new article, researchers propose a framework for using AI that includes practical guidance for applying values and that incorporates not just the tool's properties but the systems surrounding its use.
Published Child care centers aren't a likely source of COVID-19 spread, study says (via sciencedaily.com) Original source
Parents who send their children to child care can breathe a little easier. New research shows that children in daycare were not significant spreaders of COVID-19.
Published Testosterone hormone therapy for transmasculine individuals is safer than previously thought, researchers find (via sciencedaily.com) Original source
A common concern about gender-affirming hormone therapy for transmasculine people is the risk of red blood cell volume changes and erythrocytosis, a high concentration of red blood cells, with the use of prescribed testosterone. However, researchers have found that testosterone treatment may be safer than previously reported.
Published AI may spare breast cancer patients unnecessary treatments (via sciencedaily.com) Original source
A new AI (Artificial Intelligence) tool may make it possible to spare breast cancer patients unnecessary chemotherapy treatments by using a more precise method of predicting their outcomes, reports a new study. AI evaluations of patient tissues were better at predicting the future course of a patient's disease than evaluations performed by expert pathologists.
Published Early-stage stem cell therapy trial shows promise for treating progressive MS (via sciencedaily.com) Original source
An international team has shown that the injection of a type of stem cell into the brains of patients living with progressive multiple sclerosis (MS) is safe, well tolerated and has a long-lasting effect that appears to protect the brain from further damage.
Published Innovative design achieves tenfold better resolution for functional MRI brain imaging (via sciencedaily.com) Original source
Hospital MRI scanners, using 3 Tesla magnets, provide poor spatial resolution in brain imaging. More recent 7T MRIs are better but used mainly in the rare research lab. Scientists have now supercharged the standard 7T scanner to improve the resolution by nearly a factor of 10 -- a 50-times improvement over standard 3T MRIs. The NexGen 7T can track signals through the brain and perhaps tie functional changes to brain maladies.
Published Stem cell-based treatment controls blood sugar in people with Type 1 diabetes (via sciencedaily.com) Original source
An innovative stem cell-based treatment for Type 1 diabetes can meaningfully regulate blood glucose levels and reduce dependence on daily insulin injections, according to new clinical trial results. The therapy aims to replace the insulin-producing beta cells that people with Type 1 diabetes lack. Dubbed VC-02, the small medical implant contains millions of lab-grown pancreatic islet cells, including beta cells, that originate from a line of pluripotent stem cells.
Published Lowering a form of brain cholesterol reduces Alzheimer's-like damage in mice (via sciencedaily.com) Original source
Researchers have found that a form of cholesterol known as cholesteryl esters builds up in the brains of mice with Alzheimer's-like disease, and that clearing out the cholesteryl esters helps prevent brain damage and behavioral changes.
Published Researchers develop new method for prenatal genetic testing (via sciencedaily.com) Original source
Researchers have developed a non-invasive genetic test that can screen the blood of pregnant individuals to survey all genes from the fetal genome.
Published Drones enabled the use of defibrillators before ambulance arrival (via sciencedaily.com) Original source
Researchers have evaluated the possibility of alerting drones equipped with automated external defibrillators (AED) to patients with suspected cardiac arrest. In more than half of the cases, the drones were ahead of the ambulance by an average of three minutes. In cases where the patient was in cardiac arrest, the drone-delivered defibrillator was used in a majority of cases.
Published A new diagnostic tool to identify and treat pathological social withdrawal, Hikikomori (via sciencedaily.com) Original source
Hikikomori is a pathology characterized by social withdrawal for a period exceeding six months. While first defined in Japan, the pathology is growing globally. To help better assess individuals for Hikikomori, researchers developed the the Hikikomori Diagnostic Evaluation, or HiDE, a diagnostic tool to be a guide on collecting information on the growing pathology.
Published Chlorine disinfectant is no more effective than water at killing off hospital superbug (via sciencedaily.com) Original source
Research has shown spores of Clostridioides difficile, commonly known as C. diff, are completely unaffected despite being treated with high concentrations of bleach used in many hospitals. The study's authors say susceptible people working and being treated in clinical settings might be unknowingly placed at risk of contracting the superbug.
