Does prevalence and correlate of Penile HPV Infection in a Clinic-Based Sample of Hispanic Males?
HPV infection is common among sexually active males frequenting this STI clinic. HPV types not covered by the current quadrivalent HPV vaccine were identified. Multiple HPV types in the penis are significantly related to the lifetime number of female sexual partners. The high prevalence of HPV at this particular STI clinic evidences that males need to be targeted in primary care settings if the available vaccine is to be effectively promoted. In addition, opportunities for secondary prevention of HPV in STI settings are recommended, because of the burden of anal and penile cancer documented in the island.
Based on the toxicity mechanisms of NPs, two different approaches can be applied for prediction of in vivo lung inflammogenicity. Most in vitro assays were good at detecting NPs that act via soluble ions (i.e., ZnO and CuO NP). However, in vitro assays were limited in detecting NPs acting via surface reactivity as their mechanism of toxicity, except for the haemolysis assay.
