Nanofiber Bandages Speed Healing

Cornell University researchers have identified a new way to harness the antioxidant and antibacterial properties of a botanical compound to make nanofiber-coated cotton bandages that fight infection and help wounds heal more quickly. The findings are especially important given the increasing prevalence of multidrug-resistant bacteria. Cotton gauze is one of the most common wound dressings; […]

Aggression in People With Dementia

Immigrants living with dementia were more likely to present with agitation and aggression compared with their non-immigrant counterparts, a new study by Edith Cowan University (ECU) in collaboration with The Dementia Centre, HammondCare, found. Researchers from ECU’s Centre for Research in Aged Care and HammondCare’s The Dementia Centre noted that behaviours and psychological symptoms of […]

Effective Long-Term Lupus Treatment?

Australian researchers have worked out how to fix a defect that causes lupus, and hope their world-first discovery will offer effective long-term treatment. Published in Nature Communications, the Monash University-led study found a way to reprogram the defective cells of lupus patients with protective molecules from healthy people. Using human cells, the new treatment restores […]

Cell Therapy Shows Promise for ARDS

Promising trial results indicate that a new type of cell therapy could imrove the prognosis of those who are critically ill with acute respiratory distress syndrome (ARDS) resulting from severe Covid-19. Published in the journal Nature Communications, Professor Justin Stebbing of Anglia Ruskin University (ARU) is the joint senior author of the new study investigating […]

Common Food Preservative Has Unexpected Effects on the Gut Microbiome

Food manufacturers often add preservatives to food products to keep them fresh. A primary purpose of these preservatives is to kill microbes that could break down and otherwise spoil the food.  Common additives like sugar, salt, vinegar and alcohol have been used as preservatives for centuries, but modern-day food labels now reveal more unfamiliar ingredients […]

Lighting Up Alzheimer’s-Related Proteins to Allow for Earlier Disease Detection

Many neurodegenerative diseases, including Alzheimer’s and Parkinson’s, are difficult to diagnose before symptoms begin to appear. However, disease-related biomarkers such as aggregated proteins called amyloids could provide important insight much earlier, if they can be readily detected.  Researchers publishing in ACS Sensors have developed one such method using an array of sensor molecules that can […]

Therapy Versus Medication: Comparing Treatments for Depression in Heart Disease

New research by investigators from the Department of Psychiatry and Behavioral Neurosciences at Cedars-Sinai shows that behavioral activation therapy is as effective as antidepressant medications in treating symptoms of depression in patients with heart failure. Heart failure affects nearly 6 million adults in the United States, and approximately 50% of heart failure patients experience symptoms […]

Brain Boost from Exercise: Feel-Good Hormone

A study exploring the mechanisms behind why cognitive performance improves in response to exercise, has found that dopamine plays a key role. The neurotransmitter and hormone — which is tied to pleasure, satisfaction and motivation — is known to increase when you work out. New findings suggest it is also linked to faster reaction time […]

Long COVID Fatigue Linked to Malfunctioning Mitochondria

At least 65 million people around the world have long COVID, a condition where they continue to experience COVID-19 symptoms for months after their symptoms originally start. The most common symptoms of long COVID are fatigue, dizziness, mobility issues, sleep problems, cognitive impairment, and brain fog or inability to concentrate. These types of lingering symptoms […]

Stress, Via Inflammation, Is Linked to Metabolic Syndrome

Lifestyle and genetics, and a range of other factors within and outside our control, are known to contribute to development of metabolic syndrome, a cluster of conditions that add up to increased risk for serious health problems. A new study has found that stress, through its propensity to drive up inflammation in the body, is […]
