| sexually transmitted infections and hiv: epidemiology and interventions. | although the association of hiv and sexually transmitted infections (stis) has been well known for 25 years, there is insufficient attention to stis by many hiv providers, in part because patients are asymptomatic or have nonspecific symptoms and because of provider demands and focus. optimal patient care requires frequent testing for stis as well as obtaining an accurate medical history, which requires building trust with patients and asking direct but open-ended questions about risks and sympt ... | 2010 | 21107013 |
| benzalkonium chloride causes colposcopic changes and increased susceptibility to genital herpes infection in mice. | colposcopy is widely used in clinical microbicide safety testing but not in preclinical small animal studies. endoscopic colposcopy could be employed in small animals allowing colposcopy to be used as one component in a multifactorial safety testing paradigm. | 2010 | 20803781 |
| undiagnosed hiv infection among adolescents seeking primary health care in zimbabwe. | mother-to-child transmission of human immunodeficiency virus (hiv) infection was extremely common in southern africa during the 1990s, and a substantial minority of infected infants have survived to reach adolescence undiagnosed. studies have shown a high prevalence of hiv infection in hospitalized adolescents who have features associated with long-standing hiv infection, including stunting and frequent minor illnesses. we therefore investigated the epidemiology of hiv infection at the primary c ... | 2010 | 20804412 |
| structure activity relationship of dendrimer microbicides with dual action antiviral activity. | topical microbicides, used by women to prevent the transmission of hiv and other sexually transmitted infections are urgently required. dendrimers are highly branched nanoparticles being developed as microbicides. however, the anti-hiv and hsv structure-activity relationship of dendrimers comprising benzyhydryl amide cores and lysine branches, and a comprehensive analysis of their broad-spectrum anti-hiv activity and mechanism of action have not been published. | 2010 | 20808791 |
| herpes simplex virus 2 icp0 mutant viruses are avirulent and immunogenic: implications for a genital herpes vaccine. | herpes simplex virus 1 (hsv-1) icp0(-) mutants are interferon-sensitive, avirulent, and elicit protective immunity against hsv-1 (virol j, 2006, 3:44). if an icp0(-) mutant of herpes simplex virus 2 (hsv-2) exhibited similar properties, such a virus might be used to vaccinate against genital herpes. the current study was initiated to explore this possibility. several hsv-2 icp0(-) mutant viruses were constructed and evaluated in terms of three parameters: i. interferon-sensitivity; ii. virulence ... | 2010 | 20808928 |

| evaluation of a novel serology algorithm to detect herpes simplex virus 1 or 2 antibodies. | herpes simplex virus (hsv)-type specific serology (tss) testing has been commercially available for nearly a decade. guidelines on appropriate use of such testing exist, including canadian-based recommendations. despite this, most canadian laboratories do not offer hsv-type specific serology and many provide only nontype-specific hsv serology tests. | 2010 | 20693937 |
| evaluation of an edible blue-green alga, aphanothece sacrum, for its inhibitory effect on replication of herpes simplex virus type 2 and influenza virus type a. | a hot-water extract of aphanothece sacrum, an edible aquacultured blue-green alga, was found to show a remarkable inhibitory effect on the replication of enveloped viruses including herpes simplex virus type 2 (hsv-2) and influenza virus type a (ifv-a, h1n1) in vitro. the main active components were suggested to be sulfated polysaccharides in non-dialyzable portion (aswph). aswph was found to inhibit the viral adsorption to the receptor of the host cells involved in the replication process of hs ... | 2010 | 20699552 |
| anti-herpetic activity of callissia fragrans and simmondsia chinensis leaf extracts in vitro. | the antiviral activity of callissia fragrans and simnondsia chinensis aquatic and ethanol leaf extracts, as well as purified fractions from these extracts was studied against herpetic viruses in vitro. ethanol extract of c. fragrans effectively inhibited the infection of vero cells by hsv-1, hsv-2 in vitro, while its aquatic extract inhibited only vzv. although s. chinensis leaf extract strongly inhibited all studied viruses, the selectivity index of this extract was very low, due to its high to ... | 2010 | 20700398 |
| use of acyclovir for suppression of human immunodeficiency virus infection is not associated with genotypic evidence of herpes simplex virus type 2 resistance to acyclovir: analysis of specimens from three phase iii trials. | herpes simplex virus type 2 (hsv-2) is the most common cause of genital ulcer disease and is a cofactor for hiv-1 acquisition and transmission. we analyzed specimens from three separate phase iii trials of acyclovir (acv) for prevention of hiv-1 acquisition and transmission to determine if failure of acv to interrupt hiv acquisition and transmission was associated with genotypic acv resistance. acyclovir (400 mg twice daily) or placebo was provided to hsv-2-infected persons at risk of hiv-1 infe ... | 2010 | 20702659 |
| aquaporin 4 antibody positive central nervous system autoimmunity and multiple sclerosis are characterized by a distinct profile of antibodies to herpes viruses. | viral infections are implicated in the onset and promotion of autoimmunity in genetically predisposed individuals. in this study, immune response patterns to herpes viruses were compared in aquaporin 4 (aqp4) antibody positive central nervous system (cns) autoimmunity and multiple sclerosis (ms). serum samples of patients with aqp4 antibody positive cns autoimmunity (n=52), relapsing-remitting ms (n=55) and controls including non-autoimmune neurological disorders and healthy individuals (n=56) w ... | 2010 | 20705110 |
| combining prevention of hiv-1, other sexually transmitted infections and unintended pregnancies: development of dual-protection technologies. | a significant number of women, especially in developing countries, need protection against more than one sexually transmitted infection (stis), for instance hiv-1 and hsv-2, and family planning methods to prevent unwanted pregnancies. dual protection technologies (dpts; also known as multipurpose technologies) are designed to address two different indications with one product. examples of dpts are vaginal products capable of preventing transmission of hiv-1 in women while simultaneously providin ... | 2010 | 21109068 |
| novel approaches to vaginal delivery and safety of microbicides: biopharmaceuticals, nanoparticles, and vaccines. | the hiv-1 epidemic remains unchecked despite existing technology; vaccines and microbicides in development may help reverse the epidemic. reverse transcriptase inhibitors (rtis) formulated in gels tenofovir (tfv) and ivrs (dapivirine) are under clinical development. while tfv or similar products may prove successful for hiv-1, alternatives to rtis may provide additional benefits, e.g., broader sti prevention. biopharmaceutical agents under development as microbicides include cyanovirin, rantes a ... | 2010 | 21109069 |
| hsv-2 seroincidence among mexican college students: the delay of sexual debut is not enough to avoid risky sexual behaviours and virus transmission. | early sexual debut is a behaviour that has been associated with acquiring sexually transmitted infections. higher schooling may delay sexual debut, thus the university population is categorised with low-risk sexual behaviours. the rate ratio of herpes simplex virus type 2 (hsv-2) seroincidence according to demographic characteristics and sexual behaviour was estimated for a cohort of university students. | 2010 | 21113070 |
