AI eye exams accurately identify heart disease risk during routine visits

A new system that uses artificial intelligence (AI) to assess cardiovascular risk based on images of the eye captured during eye exams demonstrated strong correlation with a standard cardiovascular risk assessment, according to a study presented at the American College of Cardiology’s Annual Scientific Session (ACC.26). Researchers said using AI to screen for heart disease … Read more

Drugs targeting TIE2 protein could help prevent formation of cerebral cavernous malformations

Researchers in the Perelman School of Medicine at the University of Pennsylvania have identified a cell surface receptor protein called TIE2 as the missing link between two key signaling pathways that drive the growth of blood vessel abnormalities known as cerebral cavernous malformations (CCMs). The study, to be published March 27 in the Journal of … Read more

AI-driven OCT imaging system enables precise wound healing assessment

No matter the size or severity, wounds on human skin are difficult to monitor while they heal. Biopsies disrupt the wound site and are too invasive for routine, repeated monitoring, and most medical imaging devices that could do the job are large, expensive and booked up with more pressing diagnostics. Clinicians typically resort to visual … Read more

Blood pressure readings may help identify future dementia risk

Measures of blood vessel health derived from routine blood pressure readings may help identify adults at increased risk for dementia, according to research being presented at the American College of Cardiology’s Annual Scientific Session (ACC.26). The findings from two studies that tracked patterns of arterial stiffness over time align with growing evidence that uncontrolled hypertension … Read more

Researchers identify cellular drivers of gut scarring in Crohn’s disease

As inflamed regions of the gut form scar tissue, the space within the gut lumen becomes smaller and more restricted, leading to symptoms of gut obstruction. There is currently no drug treatment available for this complication – eventually as fibrosis worsens, surgery becomes the only option. The researchers discovered that the biggest build up of … Read more

New RNA therapy enhances the heart’s ability to repair itself after injury

After a heart attack, cardiologists can reopen blocked vessels and restore blood flow, but the muscle cells that died will never be replaced. “The heart is one of the organs with the least ability to regenerate,” said Ke Cheng, Alan L. Kaganov Professor of Biomedical Engineering at Columbia Engineering. “The spontaneous regeneration power is very, very limited.” In … Read more

Single receptor PAR1 controls opposing responses in blood vessels

Researchers at the University of California San Diego have uncovered how a single protein triggers two opposite responses in blood vessels – one inflammatory and one protective. This protein, a cell-surface receptor called protease-activated receptor-1 (PAR1), plays a critical role in maintaining the structural integrity of our blood vessels. Understanding how PAR1 switches between healing … Read more

Novel microneedle patch accelerates healing of chronic diabetic wounds using light

Researchers from Nanjing Drum Tower Hospital, Southeast University, and Wenzhou Medical University have developed a novel microneedle patch that combines MXene hydrogel with nitric oxide (NO) and hypoxia-inducible factor-1α (HIF-1α) plasmid for enhanced diabetic wound treatment. This study, published in the journal Engineering, presents a promising approach to addressing the chronic and non-healing wounds often … Read more

How PIEZO2 Senses Touch: New Insights into Molecular Mechanisms & Sensory Disorders

Archyde The sensation of touch, from a gentle tap to the feeling of clothing against skin, relies on a complex network of nerve cells and specialized proteins. Scientists have long known… You can read the full story here: How PIEZO2 Senses Touch: New Insights into Molecular Mechanisms & Sensory Disorders. Source link

Satellite livers could provide booster function for patients awaiting transplants

More than 10,000 Americans who suffer from chronic liver disease are on a waitlist for a liver transplant, but there are not enough donated organs for all of those patients. Additionally, many people with liver failure aren’t eligible for a transplant if they are not healthy enough to tolerate the surgery. To help those patients, … Read more
