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 To administer ACT, T cells are withdrawn from a patient and cultivated in a laboratory (ex vivo) for weeks or months, until a massive number of cells are available to be injected back into the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.

A hormone replacement therapy may protect memory for some women, according to a new USC-led study.

The findings by USC researchers are the latest to indicate that hormone replacement therapy may have some benefits, deepening scientific discussions about the pros and cons of the menopausal treatment.

San Francisco, CA—Picture a bare wire, without its regular plastic coating. It’s exposed to the elements and risks being degraded. And, without insulation, it may not conduct electricity as well as a coated wire. Now, imagine this wire is inside your brain.

Diffuse large B-cell lymphoma (DLBCL) is an aggressive cancer and the most frequently diagnosed non-Hodgkin lymphoma worldwide (nearly 40% of cases). Recent advancements indicate that both the prognosis and choice of treatment of DLBCL may depend on identifying its molecular subtype. In a report in the Journal of Molecular Diagnostics, researchers describe their development of a reliable, accessible, rapid, and cost-effective new gene expression signature assay that can enhance lymphoma management by helping to match tumors with the appropriate targeted therapy.

Users of statins, widely prescribed for prevention of cardiac disease, have a 27% lower risk of contracting a Staphylococcus aureus (S. aureus) bloodstream infection outside of a hospital, according to a new study in Mayo Clinic Proceedings. Researchers report that statin use, especially among elderly patients with preexisting chronic conditions such as diabetes, kidney, or liver disease, may be protective against this serious bloodstream infection. As the western world's population is aging and more people live with chronic medical conditions, any potential preventive effect of statins could have important clinical implications.

While immune cells called neutrophils are known to act as infantry in the body’s war on germs, a National Institutes of Health-funded study suggests they can act as medics as well. By studying rodents, researchers showed that instead of attacking germs, some neutrophils may help heal the brain after an intracerebral hemorrhage, a form of stroke caused by ruptured blood vessels. The study suggests that two neutrophil-related proteins may play critical roles in protecting the brain from stroke-induced damage and could be used as treatments for intracerebral hemorrhage.
