type-specific cervico-vaginal human papillomavirus infection increases risk of hiv acquisition independent of other sexually transmitted infections.sexually transmitted infections (stis) such as herpes simplex virus (hsv)-2 are associated with an increased risk of hiv infection. human papillomavirus (hpv) is a common sti, but little is know about its role in hiv transmission. the objective of this study was to determine whether cervico-vaginal hpv infection increases the risk of hiv acquisition in women independent of other common stis.201020386706
chronic viral infection and primary central nervous system malignancy.primary central nervous system (cns) tumors cause significant morbidity and mortality in both adults and children. while some of the genetic and molecular mechanisms of neuro-oncogenesis are known, much less is known about possible epigenetic contributions to disease pathophysiology. over the last several decades, chronic viral infections have been associated with a number of human malignancies. in primary cns malignancies, two families of viruses, namely polyomavirus and herpesvirus, have been ...201020387126
the glycoproteins c and g are equivalent target antigens for the determination of herpes simplex virus type 1-specific antibodies.seroreactivity to the glycoproteins c and g of herpes simplex virus type 1 (hsv-1) was compared in 310 serum samples using a western blot assay containing a whole antigen extract of hsv-1 and an elisa employing gc1 isolated from hsv-1. the prevalence of reactivity to gc1 was 75.8% by western blot and 73.9% by elisa, while antibody responses to gg1 were detected in 72.9% of sera by western blot. an absolute correlation of 96.1% between the reactivity to gc1 and gg1 was demonstrated using the west ...201020171247
estradiol limits viral replication following intravaginal immunization leading to diminished mucosal igg response and non-sterile protection against genital herpes challenge.previously we reported that ovariectomized (ovx) mice receiving estradiol (e) prior to immunization with an attenuated strain of hsv-2 (tk-hsv-2) were not protected. lack of protection in the e group was because of the inability of tk-hsv-2 to penetrate the thick keratinized epithelium. in this study, we determined the outcome of immunization after the thickening of vaginal epithelium following e-treatment waned. ovx, c57bl/6 mice were given progesterone (p), e or saline (s) for 3 days and immun ...201020070285
a highly lipophilic sulfated tetrasaccharide glycoside related to muparfostat (pi-88) exhibits virucidal activity against herpes simplex virus.although sulfated polysaccharides potently inhibit the infectivity of herpes simplex virus (hsv) and human immunodeficiency virus in cultured cells, these compounds fail to show protective effects in humans, most likely due to their poor virucidal activity. herein we report on sulfated oligosaccharide glycosides related to muparfostat (formerly known as pi-88) and their assessment for anti-hsv activity. chemical modifications based on the introduction of specific hydrophobic groups at the reduci ...201020176055
bayesian adjustment for exposure misclassification in case-control studies.poor measurement of explanatory variables occurs frequently in observational studies. error-prone observations may lead to biased estimation and loss of power in detecting the impact of explanatory variables on the response. we consider misclassified binary exposure in the context of case-control studies, assuming the availability of validation data to inform the magnitude of the misclassification. a bayesian adjustment to correct the misclassification is investigated. simulation studies show th ...201020087839
