Medical Xpress / Largest genetic study of schizophrenia and African ancestry reveals shared biology across global populations
A team of researchers has conducted the largest and most comprehensive genome-wide association study (GWAS) to date of schizophrenia in individuals of African ancestry.
Medical Xpress / Lithium study yields insights in the fight against HIV
Lithium, a widely used treatment for bipolar disorder and other mood disorders, has shown early promise in suppressing HIV, McGill University researchers report.
Medical Xpress / Treating psoriasis without side effects: Light-activated molecules demonstrate potential
Researchers from the Institute for Advanced Chemistry of Catalonia (IQAC) of the Spanish National Research Council (CSIC) have developed a series of light-activatable drug candidates that could serve as a potential treatment ...
Medical Xpress / Brain navigation study reveals function of an unconventional electrical-signaling mode in neurons
Navigating the world is no mean feat, especially when the world pushes back. For instance, airflow hitting a fly on its right side can, after a turn, become a headwind. To stay on course, the fly's brain must interpret sensations ...
Medical Xpress / Donated blood has a shelf life, and a new test tracks how it ages
A new, fast and easy test could revolutionize blood transfusions, giving blood centers and hospitals a reliable way to monitor the quality of red blood cells after they sit for weeks in storage.
Medical Xpress / Small number of 'highly plastic' cancer cells drive disease progression and treatment resistance
A small number of cancer cells with the ability to change their identities and behaviors appear to be a key driver of cancer progression and its ability to evolve resistance to treatment.
Medical Xpress / Trees, not grass and other greenery, associated with lower heart disease risk in cities
A multi-institutional study led by the University of California, Davis, finds that living in urban areas with a higher percentage of visible trees is associated with a 4% decrease in cardiovascular disease. By comparison, ...
Medical Xpress / Manipulating blood CO₂ levels may help clear toxic proteins from the brain
Abnormal clumps of proteins like α-synuclein, amyloid beta and tau are associated with neurodegenerative conditions like Parkinson's and Alzheimer's disease, but a waste removal mechanism called the glymphatic pathway can ...
Medical Xpress / Delayed stroke care linked to increased disability risk
Gaps in the U.S. stroke transfer system are drastically reducing survivors' chances of receiving critical treatment and increasing the likelihood that they will leave the hospital with a disability, according to a study published ...
Medical Xpress / Childhood ADHD linked to midlife physical health problems
People who have ADHD traits at age 10 are more likely than those without such traits to have physical health problems and to report physical health-related disability at age 46, according to a study led by University College ...
Medical Xpress / Super-enhancers in cancer cells trigger DNA breaks and error-prone repair cycles
A new study shows that cancer damages its own DNA by pushing key genes to work too hard. Researchers found that the most powerful genetic "on switches" in cancer cells, called super-enhancers, drive unusually intense gene ...
Medical Xpress / Scientists uncover hidden cells fueling brain cancer—and a drug that could stop them
A team of Canadian scientists has uncovered a new way to slow the growth of glioblastoma, the most aggressive and currently incurable form of brain cancer—and identified an existing medication that could treat it.
