Female sex workers in Kigali, Rwanda: a key population at risk of HIV, sexually transmitted infections, and unplanned pregnancy.

Female sex workers (FSWs) were recruited from known hotspots in Kigali, Rwanda, and offered free, anonymous human immunodeficiency virus (HIV) counseling and testing, diagnosis and treatment of sexually transmitted infections (STIs) and long-acting reversible contraception (LARC). From September 2012 to March 2015, 1168 FSWs sought services, including 587 (50%) who were HIV-positive. More than 90% had previously tested for HIV, and 26% who reported previously testing negative had seroconverted.

Antiangiogenic effects of a novel synthetic curcumin analogue in pancreatic cancer.

Hypoxia-inducible factors (HIFs) and NF-κB play essential roles in cancer cell growth and metastasis by promoting angiogenesis. Heat shock protein 90 (Hsp90) serves as a regulator of HIF-1α and NF-κB protein. We hypothesized that curcumin and its analogues EF31 and UBS109 would disrupt angiogenesis in pancreatic cancer (PC) through modulation of HIF-1α and NF-κB.

Effects of naloxone, serotonin, and dopamine on reproduction of the freshwater crab Barytelphusa guerini.

Several investigators suggest a relationship between neurotransmitters, serotonin (also called 5-hydroxytryptamine, 5-HT), and dopamine (DA) in the regulation of growth and reproductive development of vertebrate species, rather than the invertebrate species. In this study, we evaluated the role of 5-HT and DA in reproductive development of an invertebrate species, the freshwater crab Barytelphusa guerini. We tested the effects of 5-HT both alone and combined, and also the effects of an opioid antagonist naloxone, on reproductive development of B.
