The system showed acceptable expert authority and preliminary internal consistency, suggesting potential applicability for nursing quality monitoring.
Researchers discovered that metformin significantly reduces the risk of early and preterm births for mothers at high metabolic risk. In a study published in the New England Journal of Medicine, women taking metformin had a 35% lower odds of giving birth prematurely compared to those receiving a placebo.
Researchers found that bats have evolved genes that enable them to live longer without disease, and that this adaptability is linked to their ability to resist cancer. The study suggests that bats' unique genetic mechanism allows them to diversify gene function, potentially leading to new insights for human health.
Researchers develop a polymer nanogel system called Nano-ERASER that uses antibodies to degrade targeted proteins, inducing neuron regeneration and restoring neural circuits in human brain organoids and mice with Alzheimer's disease. The study provides a critical step in regenerative neuroscience, offering a roadmap for a potential cure.
A new study found that people with Parkinson’s disease have altered extracellular vesicles in their stool samples, suggesting changes in microbial communication. The study suggests that these vesicles could serve as biomarkers for the disease and potentially reveal new therapeutic targets.
Scientists at HZB developed a solution to improve perovskite growth on textured silicon substrates, using a caesium chloride seed layer to enhance uniformity and prevent lead iodide formation. This boosts efficiency in tandem solar cells to record values.
A new study from Northwestern University found that coronary calcium scans are most valuable for patients with borderline cardiovascular risk. The scans added relatively little to risk prediction from existing risk calculators, but provided a clearer picture for those at intermediate risk. The study suggests that not everyone needs a c...
A US study found that low neighborhood opportunity is associated with a higher concentration of fatal police pursuit incidents. Disproportionate impact on low-opportunity communities was observed, suggesting that future research should examine pursuit frequency and lethality differences.
GLP-1 receptor agonists were associated with lower mortality and cardiovascular events in serious mental illness patients. The benefits were evident within 1 year and were consistent across subgroups, driven by semaglutide and tirzepatide.
Scientists have developed a technique to measure the spectrum of a single molecule without destroying it. By using quantum information processing, they were able to detect the absorption of individual photons and identify a characteristic molecular vibration. This breakthrough enables precise spectroscopy of complex molecules and paves...
