To test the feasibility of localized intravaginal therapy directed to neighboring lymph nodes, the transport of quantum dots across the vaginal wall was investigated. Quantum dots instilled into the mouse vagina were transported across the vaginal mucosa into draining lymph nodes, but not into distant nodes. Most of the particles were transported to the lumbar nodes; far fewer were transported ...

Great questions! Here's the scoop on what you heard: according to a four-year study conducted by the Joint United Nations Programme on HIV/AIDS (UNAIDS) [2], women who used nonoxynol-9 (N-9) gel were infected with human immunodeficiency virus (HIV) at a higher rate than those who used a placebo gel. Though N-9 isn?t effective at protecting against HIV and other sexually transmitted infections (...
