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 / 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 ...
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 / 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 / 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 / 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 / Cell signaling step sharpens understanding of how the body responds to exercise's energy demands
Researchers have investigated the role of a certain enzyme in regulating energy in muscle and exercise performance for decades, but a new study by Virginia Tech scientists has identified more precisely than ever how this ...
Medical Xpress / Yawns in healthy fetuses might indicate mild distress
Even in the womb, where all oxygen is provided by the parental placenta, fetuses can—and do—yawn. More yawns during observation were associated with a lower weight at birth—potentially indicating mild fetal stress in ...
Medical Xpress / Vitamin B7 reveals a new metabolic weak spot in some cancers
A research group at the University of Lausanne (Unil) has identified a new mechanism that exposes the vulnerability of tumor cells when they are deprived of vitamin B7. The ability of cells to adapt to fluctuations in nutrient ...
Medical Xpress / In Rett syndrome, leaky brain blood vessels traced to microRNA
MIT researchers have discovered that two common genetic mutations that cause Rett syndrome each set off a molecular chain of events that compromises the structural integrity of developing brain blood vessels, making them ...
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 ...
