Medical Xpress / Lab-grown human retina reveals how vision loss begins in Batten disease
Researchers have developed a new way to study CLN3-Batten disease, a rare inherited condition that causes early vision loss in children followed by progressive neurological decline. Their findings offer new insight into how ...
Medical Xpress / Novel molecular shuttle could expand delivery of medicines across the blood–brain barrier
The blood–brain barrier (BBB) is a protective filter that lines the brain's blood vessels and is notoriously hard to penetrate, making the treatment of brain disorders very difficult. Strategies designed to breach the BBB ...
Medical Xpress / Gut bacteria may communicate differently with the human body in patients with Parkinson's disease
A new study from the University of Oulu suggests that gut bacteria may send different biological signals in Parkinson's disease. The findings add to growing evidence that changes in the gut could be linked to Parkinson's ...
Medical Xpress / Can research gleaned from a hibernating snail save a human heart?
University of Alberta researchers have discovered a novel drug that unlocks the secret of snail hibernation, allowing them to safely put non-hibernating animal organs into a deep metabolic sleep. The study, published in Nature ...
Medical Xpress / Standard breast cancer classification may overlook important differences
Breast cancer is often classified as either estrogen receptor-positive (hormone-sensitive) or not. However, a new study from Karolinska Institutet suggests that this simplified classification may overlook important biological ...

It's an increasingly popular scan that measures calcium in the heart's arteries and helps predict the risk of future heart disease. But according to a new Northwestern Medicine study, the quick and inexpensive test—known ...
Medical Xpress / Mimicking natural connections could improve rotator cuff repair
Researchers have developed a "scaffold" that mimics natural tissue and could lead to more durable rotator cuff repairs, including for large injuries and cases involving bone and tissue degeneration that are often the most ...
Medical Xpress / Vagus nerve stimulation hints at a vascular pathway to support long-term learning
Do you ever feel like sometimes you can master a new dance step almost immediately, while other times you struggle to nail it despite repeated practice? This might be due to skill or effort, but also to something less obvious: ...
Medical Xpress / Overuse of inhalers found to increase heart attack risk in asthma and COPD patients
Overuse of reliever inhalers is associated with higher risks of developing and dying from cardiovascular disease, including heart failure, heart attack and ischemic stroke, in patients with asthma and COPD, according to a ...
Medical Xpress / Inspired by soap bubbles, scientists reproduce alveolar movement in artificial lung model
Almost everyone has blown a soap bubble through a straw at least once. Inspired by this thin soap bubble film, an artificial lung that breathes like a real lung has been developed. A research team led by Professor Sungjune ...
