Medical Xpress / Are heart failure and atrial fibrillation the same disease? Study reveals shared genetic and molecular mechanics
New research from a multi-institutional team, published in Nature Cardiovascular Research, reveals that heart failure and atrial fibrillation share underlying genetic and molecular mechanisms, suggesting that the two cardiovascular ...
Medical Xpress / Study of 11,000 tumors maps 134 DNA damage signatures across 16 cancers
A team of cancer genomics scientists from The University of Manchester and The Institute of Cancer Research, London, forensically examined the genetic make-up of tumors in 16 different cancers. Their findings, which have ...
Medical Xpress / Teens who sleep past 8 a.m. eat more and move less, study suggests
When people think about ways to improve cardiovascular health, diet and exercise are often at the top of the list. But long-term health, especially in adolescents, might start with something more fundamental: sleep. A new ...
Medical Xpress / Over the past decade, early-stage drug innovation has shifted toward China, researchers find
Early-stage drug development worldwide has nearly doubled over the past decade and shifted from a U.S.-dominated model to a dual hub centered in the United States and China, according to new research described by Georgetown ...
Medical Xpress / Why some cancer therapies don't work for all patients: A tumor backup survival pathway
Drugs that block enzymes called tyrosine kinases are among the most effective targeted therapies for cancer. However, they typically work for only 40% to 80% of the patients who would be expected to respond to them. In a ...
Medical Xpress / Staying active throughout middle age can cut women's risk of premature death in half
Women who consistently met physical activity guidelines throughout middle age had half the risk of dying from any cause compared to women who remained inactive, according to a paper published in PLOS Medicine by Binh Nguyen ...
Medical Xpress / Breakdown products from 'eco-friendly' plastics impede fetal development in mice, study shows
When the "eco-friendly" bioplastic, polylactic acid (PLA), biodegrades, the resulting nanoplastics can accumulate in the fetuses of pregnant mice and interfere with fetal growth. Yichao Huang and De-Xiang Xu of Anhui Medical ...
Medical Xpress / How the brain fine-tunes fear as threats fade
Researchers at Tulane University have identified brain circuits that help determine how fear responses change as perceived threats diminish, offering new insight into how the brain regulates defensive behavior and why those ...
