To help Harris County target its preventive strategies for sudden unexpected infant death (SUID), researchers at The University of Texas Health Science Center at Houston (UTHealth) have identified areas of the county where these tragic deaths are most likely to occur. Their research appears in the American Journal of Forensic Medicine and Pathology and was […]
Researchers from Singapore and South Korea have uncovered new details of a brain pathway that can cause impulsive behaviours. Using mice, the research team led by Professor George Augustine from Nanyang Technological University, Singapore (NTU Singapore), discovered that impulsive behaviour is triggered when the brain signalling chemical dopamine is passed to an unexpected area of […]
Researchers from the University of Alabama at Birmingham Department of Ophthalmology and Visual Sciences, along with collaborators from the University of Iowa, have discovered a genetic biomarker that is associated with age-related macular degeneration and delayed rod-mediated dark adaptation—the first visual function for incident AMD in older adults with normal macular health and early AMD. […]
A new mechanism for activating the immune system against cancer cells allows immune cells to detect and destroy cancer cells better than before, according to a study published this week in the journal Nature. The study was led by Prof. Nick Haining, of Harvard Medical School, and co-authored by Prof. Erez Levanon, doctoral student Ilana […]
Scientist have long known that bacteria in the intestines, also known as the microbiome, perform a variety of useful functions for their hosts, such as breaking down dietary fiber in the digestive process and making vitamins K and B7. Yet a new study unveils another useful role the microbiome plays. A team of researchers from […]
A team of Rutgers scientists, including Leonard Lee and Shaohua Li, have taken an important step toward the goal of making diseased hearts heal themselves—a new model that would reduce the need for bypass surgery, heart transplants or artificial pumping devices. The study, recently published in Frontiers in Cell and Developmental Biology, involved removing connective […]
For the first time, researchers have identified that an immune cell subset called gamma delta T cells that may be causing and/or perpetuating the systemic inflammation found in normal aging in the general geriatric population and in HIV-infected people who are responding well to drugs (anti-retrovirals). Even with effective viral control, HIV-infected individuals are at […]
Patients diagnosed with pancreatic cancer face a poor prognosis because the tumor forms dense scar-like tissue that is difficult for chemotherapy drugs to penetrate, but a new model may help researchers develop new therapies. “More than 85 percent of pancreatic tumors form this fibrous tissue,” explained Assistant Professor Joshua Reineke of the South Dakota State […]
A new study by researchers at Karolinska Institutet supports the theory that replacement of dysfunctional immune cells in the brain has therapeutic potential for neurodegenerative diseases like ALS and Alzheimer’s disease. The study, which involved repopulating the brain with new immune cells in an experimental disease model, is published in Nature Communications. Macrophages are immune […]
‘Trojan horse’ antibiotic can kill drug-resistant superbugs from WITHIN ‘by hijacking their defences’ The drug, called cefiderocol, works by attaching itself on to iron molecules Once allowed inside the bacterial cell, it can destroy it from within, experts say Experts now hope it will top up the world’s dwindling arsenal of antibiotics Antibiotic resistance is […]
