A large study found that postmenopausal women with higher trans fat intake have an increased risk of ischemic stroke. Aspirin use was shown to reduce this risk. The study, published in Annals of Neurology, highlights the importance of following a diet low in trans fats and adding an aspirin regimen to help women reduce their stroke risk.
Scientists have combined NO- and H2S-releasing designer aspirins into a hybrid substance called NOSH-aspirin, which appears more effective in controlling cancer growth than either of its predecessors. The new compound inhibits the growth of various cancer cells, including breast, colon, and leukemia, with minimal harm to normal cells.
