Simple surgical technique associated with significant reduction in the risk of atrial fibrillation after cardiac surgery
A simple surgical technique during cardiac surgery was associated with a 56 percent reduction in the incidence of an irregular heart rhythm known as atrial fibrillation that can lead to stroke, with no added risks or side effects, according to a new.....»»
Altered fat metabolism, enzyme, likely plays key role in Lou Gehrig’s disease
A new study using genetically engineered mice and human cell and tissue samples has added to evidence that higher levels of inflammatory chemicals involved in fat metabolism occur in people with amyotrophic lateral sclerosis (ALS), the neuromuscular.....»»
Using T cells to target malignant brain tumors
Doctors and scientists have successfully tested a neoantigen-specific transgenic immune cell therapy for malignant brain tumors for the first time using an experimental model in mice......»»
Singing, being male, and being an adult tend to produce more respiratory aerosols, study finds
A new study measured respiratory particles produced from people singing or playing instruments. Is singing worse than talking when it comes to how many particles are being emitted? Yes, according to the study. And the louder one talks or sings, the w.....»»
Researchers find benefits and drawbacks to two-step surgical approach for "leaky heart valves"
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
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......»»
Vascular defects appear to underlie the progression of Parkinson"s disease
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 ni.....»»
Breaking down fungal biofilm defenses provides potential path to treating sticky infections
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 throu.....»»
Microbiome discovery may open new doors to development of treatments for gastrointestinal diseases
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......»»

Scientists have engineered bacteria that can detect specific molecules in the gut......»»
Team engineers new way to get medication past blood-brain barrier
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 t.....»»
Scientists employ digital esophagus to battle Barrett’s
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.....»»
For stem cells, bigger doesn’t mean better
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 -- re.....»»
Illuminating dark matter in human DNA
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 h.....»»
Malaria: New knowledge about naturally acquired immunity may improve vaccines
When you have become immune to malaria after having contracted the disease, it seems that the body uses a more efficient protection than if you have been vaccinated against the deadly disease. The researchers believe the new findings may be used to i.....»»
Noninvasive brain biopsy shows improved sensitivity in tumor detection
A team of researchers has developed a noninvasive diagnostic method that may one day replace the biopsy with a simple blood test......»»
Obesity raises the risk of gum disease by inflating growth of bone-destroying cells
Chronic inflammation caused by obesity may trigger the development of cells that break down bone tissue, including the bone that holds teeth in place, according to new research that sought to improve understanding of the connection between obesity an.....»»
Low-cost medicine effective in treating high blood pressure for some
Medical researchers found that chlorthalidone was effective in lowering blood pressure in individuals with advanced kidney disease......»»
Moderate amounts of caffeine not linked to maternal health risks
Consuming a low amount of caffeine during pregnancy could help to reduce gestational diabetes risk, according to researchers......»»
