Medical Xpress / Can intimate relationships affect your heart? New study says 'yes'
With heart disease as the leading cause of death worldwide, there is growing recognition that recovery is not only physical but also emotional and social. A new study shows that strong and supportive relationships can indeed ...
Medical Xpress / Higher maternal vitamin D during pregnancy tied to less childhood tooth decay
Zhejiang University School of Medicine investigators reported that higher maternal plasma 25-hydroxyvitamin D levels across pregnancy aligned with lower odds of early childhood caries in children.
Medical Xpress / Neurons use physical signals, not electricity, to stabilize communication
Every movement you make and every memory you form depends on precise communication between neurons. When that communication is disrupted, the brain must rapidly rebalance its internal signaling to keep circuits functioning ...
Medical Xpress / When neural spikes break time's symmetry: Linking the information-theoretic cost of brain activity to behavior
What if we could peer into the brain and watch how it organizes information as we act, perceive, or make decisions? A new study has introduced a method that does exactly this—not just by looking at fine-grained neuronal ...
Medical Xpress / 'Zombie' cells spark inflammation in severe fatty liver disease, researchers find
Mayo Clinic researchers have uncovered how aging "zombie cells" trigger harmful inflammation that accelerates a severe and increasingly common form of fatty liver disease called metabolic dysfunction-associated steatohepatitis ...
Medical Xpress / How the immune system keeps mucosal fungi in check
The microbiome not only consists of bacteria, but also of fungi. Most of them support human and animal health. However, some fungi also have pathogenic potential. For instance, the yeast Candida albicans can grow in an uncontrolled ...
Medical Xpress / Common medicines may influence CRISPR therapy outcomes and precision cancer treatment
In a new study, scientists at the Max Planck Institute for Evolutionary Anthropology in Leipzig analyzed the impact of more than 2,000 clinically approved drugs on DNA repair and CRISPR genome editing outcomes. They found ...
Medical Xpress / Gene therapy for hereditary spastic paraplegia hits proof-of-principle milestone
There is no cure for the rare disease Hereditary Spastic Paraplegia (HSP), but researchers from Drexel University's College of Medicine and the UMass Chan Medical School have achieved proof-of-principle success with "silence ...
Medical Xpress / Neurons use simple rules to localize genetic messages, scientists discover
Scientists found that messenger RNA (mRNA) molecules that carry genetic instructions to the far reaches of neurons in the brain tend to cluster together mostly because they are abundant, not because they move in coordinated ...
Medical Xpress / AI helps explain how covert attention works and uncovers new neuron types
Shifting focus on a visual scene without moving our eyes—think driving, or reading a room for the reaction to your joke—is a behavior known as covert attention. We do it all the time, but little is known about its neurophysiological ...
Medical Xpress / A testing paradox: Rising sexually transmitted infections cases may mask actual decline in infections
For several years, pre-exposure prophylaxis against HIV (PrEP) has been a major success in preventing new cases. However, individuals on PrEP typically engage in riskier sexual behavior and thus are more susceptible to acquiring ...
Medical Xpress / AI-engineered nasal spray antiviral platform developed to block flu and COVID-19
Respiratory viruses that have diverse strains and mutate rapidly, such as influenza and COVID-19, are difficult to block perfectly with vaccines alone. To solve this problem, KAIST's research team has successfully developed ...
