Medical Xpress / Superagers' brains have a 'resilience signature,' and it's all about neuron growth
Brains of older adults with super-healthy cognition grow more new neurons than those of their peers, according to a study from UIC, Northwestern University and the University of Washington. Researchers found that the brains ...
Medical Xpress / Skeletal muscle retains a 'molecular memory' of repeated disuse, study finds
Muscle loss (atrophy) due to inactivity is common after illness, injury, hospitalization or falls, and becomes increasingly frequent with aging. New research published in Advanced Science shows that skeletal muscle retains ...
Medical Xpress / Surprising culprit leads to chronic rejection of transplanted lungs and hearts
Despite advances in the field of organ transplantation, long-term organ rejection that can become apparent a decade or more after a heart or lung transplant remains a common problem for patients. This chronic organ failure ...
Medical Xpress / Keto diet may restore exercise benefits in people with high blood sugar
To be healthy, conventional wisdom tells us to exercise and limit fatty foods. Exercise helps us lose weight and build muscle. It makes our hearts stronger and boosts how we take in and use oxygen for energy—one of the ...
Medical Xpress / Women show greater tau buildup and faster cognitive decline than men in Alzheimer's
Tau proteins act like the brain's maintenance crew, helping maintain the structure and proper function of brain cells. In neurodegenerative diseases such as Alzheimer's, the tau proteins can form tangles that disrupt normal ...
Medical Xpress / Vitamin B3 therapy offers hope for fatal childhood disease
Scientists at Gladstone Institutes have flipped the traditional approach to finding potential treatments for deadly diseases. Instead of starting with a disease and hunting for a cure, they began with vitamins and systematically ...
Medical Xpress / Long-term brain effects of COVID-19 vs. flu: Study reveals key differences
Even a mild case of COVID-19 or the flu can impact the body long after the fever and cough fade, according to new Tulane University research that may help explain why some people struggle to feel fully recovered weeks or ...
Medical Xpress / Single daily pill shows promise as replacement for complex, multi-tablet HIV treatment regimens
A new, daily oral tablet that combines two current HIV treatment medications, bictegravir and lenacapavir (BIC/LEN), could effectively replace more complicated HIV treatment regimens used by people living with HIV who are ...
Medical Xpress / How ketogenic diets help prevent seizures
A ketogenic diet—one that is high in fat and extremely low in carbohydrates—has been known for decades to reduce seizures in some epilepsy patients. But how the highly restrictive diet achieves these effects has not previously ...
Medical Xpress / Neurosurgeons are really good at removing brain tumors—they're about to get even better
When removing cancerous tissue in the brain, neurosurgeons often use "awake brain mapping" to minimize the risk of causing unintended disruptions to a patient's quality of life while removing as much tumor as possible. This ...
Medical Xpress / Differing immune responses in infants may explain increased severity of RSV over SARS-CoV-2
Young infants hospitalized with respiratory syncytial virus (RSV) often become much sicker than those infected with SARS-CoV-2, the virus that causes COVID-19. In a study published in Science Translational Medicine, scientists ...
Medical Xpress / Keeping neurons on the right path: Scientists identify key driver of cortical layering during brain development
The cerebral cortex, the brain's outermost region responsible for higher cognitive functions, depends on a highly ordered, layered structure. Its proper development requires newly generated neurons to migrate to precise locations ...
