Enterococci are hardy microbes that thrive in the gastrointestinal tracts of nearly all land animals, including our own, and generally cause no harm. But their ruggedness has lately made them leading causes of multi-drug-resistant infections, especially in settings like hospitals where antibiotic use disrupts the natural balance of intestinal microbes.
A unique platform that resulted in a promising HIV vaccine has also led to a new, highly effective vaccine against tuberculosis that is moving toward testing in humans.
Women have many options for oral contraceptives that are safe, effective and reversible, but despite decades of research, men have none. Now, scientists report a rat study in ACS' Journal of Medicinal Chemistry that shows they finally have a good lead for a male birth control pill. It's based on ouabain, a plant extract that African warriors and hunters traditionally used as a heart-stopping poison on their arrows.
Attention-deficit/hyperactivity disorder (ADHD) increases the risk of subsequent sexually transmitted infections (STIs) among adolescent and young adult populations by about three times, reports a study published in the January 2018 issue of the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP)
Scientists have shown how alcohol damages DNA in stem cells, helping to explain why drinking increases your risk of cancer, according to research part-funded by Cancer Research UK and published in Nature today.
A new Tel Aviv University study reveals that hyperbaric oxygen treatments may ameliorate symptoms experienced by patients with Alzheimer's disease.
Reducing a protein found in the mitochondria of cardiac muscle cells initiates cardiac dysfunction and heart failure, a finding that could provide insight for new treatments for cardiovascular diseases, a study led by Georgia State University has shown.
In recent years, the search for new cancer treatments has increasingly focused on immunotherapies that harness the body's own defenses to fight tumors. Adoptive cell therapy (ACT) is a powerful immunotherapeutic strategy that can effectively control some cancers but that also has drawbacks. To administer ACT, T cells are withdrawn from a patient and cultivated in a laboratory (ex vivo) for weeks or months, until a massive number of cells are available to be injected back into the patient. During ex vivo cultivation, the T cells often lose potency and life span.
A joint study conducted by scientists at the National Academy of Sciences in Belarus and Kazan Federal University in Russia, looks at the role of nitric oxide (NO) in brain tissue in simulated ischemia in rats.
The vaccine that protects against cancer-causing types of human papillomavirus (HPV) also prevents an uncommon but incurable childhood respiratory disease, according to a new study published in The Journal of Infectious Diseases. The findings suggest that the chronic and difficult-to-treat condition, recurrent respiratory papillomatosis, is disappearing in Australian children as a result of the nation’s highly successful HPV vaccination program.
