| Researchers find benefits and drawbacks to two-step surgical approach for 'leaky heart valves' Posted: 13 Nov 2021 03:14 PM PST Patients with mitral and tricuspid valve regurgitation, a condition sometimes called 'leaky heart valves,' appeared to do better after two years if they had a tricuspid valve repair at the time of mitral valve surgery, according to a new study. |
| Anxiety cues found in the brain despite safe environment Posted: 13 Nov 2021 04:25 AM PST Researchers used a virtual-reality environment to understand the impact anxiety has on the brain and how brain regions interact with one another to shape behavior. |
| For stem cells, bigger doesn’t mean better Posted: 13 Nov 2021 04:25 AM PST A new study suggests that enlargement of stem cells contributes to age-related decline in function. The researchers found that blood stem cells, which are among the smallest cells in the body, lose their ability to perform their normal function -- replenishing the body's blood cells -- as they grow larger. When the cells were restored to their usual size, they behaved normally again. |
| Illuminating dark matter in human DNA Posted: 13 Nov 2021 04:22 AM PST Researchers have produced a single-cell chromatin atlas for the human genome. Delineating chromatin regions in cells of different human tissue types would be a major step toward understanding the role of gene regulatory elements (non-coding DNA) in human health or disease. |
| Vascular defects appear to underlie the progression of Parkinson's disease Posted: 13 Nov 2021 04:22 AM PST In an unexpected discovery, researchers have identified what appears to be a significant vascular defect in patients with moderately severe Parkinson's disease. The finding could help explain an earlier outcome of the same study, in which the drug nilotinib was able to halt motor and non-motor (cognition and quality of life) decline in the long term. |
| Best way to avoid procrastination Posted: 13 Nov 2021 04:22 AM PST They say procrastination is the thief of time -- actually deadlines are. New research has found that if you want someone to help you out with something, it is best not to set a deadline at all. But if you do set a deadline, make it short. |
| Breaking down fungal biofilm defenses provides potential path to treating sticky infections Posted: 12 Nov 2021 10:47 AM PST In a new study designed to better understand and combat these structures, scientists identified some of the key proteins in biofilms of the fungus Candida albicans that control both how they resist antifungal drugs and how they become dispersed throughout the body. |
| Microbiome discovery may open new doors to development of treatments for gastrointestinal diseases Posted: 12 Nov 2021 09:22 AM PST Researchers probing the gut -- 'the inner tube of life' -- have for the first time discovered specific factors in its workings that in the future may help improve treatment for patients facing gut damage or gastrointestinal disease. |
| Building bacteria to keep us well Posted: 12 Nov 2021 09:15 AM PST Scientists have engineered bacteria that can detect specific molecules in the gut. |
| Team engineers new way to get medication past blood-brain barrier Posted: 12 Nov 2021 09:15 AM PST A team of researchers has developed a new technique to open the blood-brain barrier temporarily to deliver medication to the brain. Getting medication past the brain's unique and protective blood vessels, known as the blood-brain barrier, is one of the biggest challenges in treating brain and central nervous system diseases, according to researchers. The technique uses light and nanoparticles to pry open temporarily these barriers -- called tight junctions -- to allow medication to reach its target. |
| Scientists employ digital esophagus to battle Barrett’s Posted: 12 Nov 2021 09:15 AM PST A team has developed a digital tool to better monitor a condition known as Barrett's esophagus, which affects more than 3 million people in the United States. Barrett's occurs when the mucosal lining of the lower esophagus deteriorates, altering its cellular structure, and is most common in those with chronic acid reflux. |
