New calculator reveals whether you should really worry about statin side effects

1 month 3 weeks ago
Scientists at the University of Oxford have created a calculator that predicts a person's individual risk of serious muscle disorders from statin medications. Their analysis found that more than 98% of people who qualify for statins are at low risk for these rare complications, despite widespread concerns about side effects. The study also revealed that most eligible patients are not taking statins, potentially missing important protection against heart attacks and strokes.

Scientists say creatine may help fight depression

1 month 3 weeks ago
Creatine is best known as a muscle-building supplement, but scientists are now investigating whether it could also help treat depression by boosting the brain's energy supply. A new review examined five randomized clinical trials involving 238 participants and found mixed results. Two studies, both involving women with major depressive disorder, reported that adding creatine to standard treatment improved symptoms, while three others found no meaningful benefit.

Scientists discover an unexpected way to make pancreatic cancer cells self-destruct

1 month 3 weeks ago
Researchers tested experimental PCAI compounds against pancreatic cancer cells and found they had powerful anticancer effects. One leading compound blocked more than 90% of cancer cell migration, suggesting it could help prevent the spread of tumors. Rather than suppressing cancer signaling, the treatment hyperactivated key pathways until the cells essentially self-destructed.

Arc mediates intercellular tau transmission via extracellular vesicles

1 month 3 weeks ago
Tau pathology spreads cell to cell, but the mechanisms of intercellular tau transmission remain unclear. We find that the neuronal gene Arc is critical for the release of tau in neuronal extracellular vesicles (EVs) via a direct protein-protein interaction. Brain EVs purified from transgenic rTg4510 mutant tau mice (rTg^(WT)) crossed with Arc knockout mice (rTg^(Arc KO)) contain less tau and reduced tau seeding potential. Both Arc and tau are co-packaged in mouse and human brain-derived EVs....
