Hepatocellular carcinoma (HCC) is known to be associated with both HBV and HCV. While epigenetic changes have been previously reported to be associated with hepatocellular carcinoma (HCC), whether the epigenetic profile of HBC associated HCC differs from that of HCV-associated HCC is unclear. We analyzed DNA methylation of ten genes (APC, CCND2, CDKN2A,(More)
Previous studies among women worldwide have demonstrated that infection with specific types of human papillomaviruses (HPV) is central to the pathogenesis of cervical neoplasia. There is little data, however, concerning the prevalence of specific HPV types and the association of each type with cervical neoplasia among women in sub-Saharan Africa, who remain(More)
PURPOSE Novel approaches to breast cancer screening are necessary, especially in the developing world where mammography is not feasible. In this study, we explored the hypothesis that blood-based biomarkers have potential for biomarkers for breast cancer. PATIENTS AND METHODS We first determined the frequency of aberrant methylation of four candidate(More)
We used MethyLight assays to analyze DNA methylation status of 27 genes on 49 paired cancerous and noncancerous tissue samples from non-small cell lung cancer (NSCLC) patients who underwent surgical resection. Seven genes (RARB, BVES, CDKN2A, KCNH5, RASSF1, CDH13, and RUNX) were found to be methylated significantly more frequently in tumor tissues than in(More)
OBJECTIVES To measure the risk of preterm delivery, premature rupture of membranes, infant low birth weight and infant mortality, by a population-based retrospective cohort study using Washington State birth certificate data. METHODS All women diagnosed with Chlamydia trachomatis infection (n = 851), noted with a check box on the birth certificate from(More)
We examined the feasibility of using detection of high-risk human papillomavirus (HPV) DNA in combination with the presence of aberrantly methylated genes (DAPK1, RARB, TWIST1, and CDH13) for urine-based cervical cancer screening. Urine samples from 129 Senegalese women, aged 35 years or older, 110 with (same day) biopsy-proven cervical neoplasia [cervical(More)
BACKGROUND Women infected with human immunodeficiency virus type 1 (HIV-1) and -2 may be at higher risk of developing cervical cancer than uninfected women. We assessed the relationships among human papillomavirus (HPV) types and persistence, HIV-1 and/or HIV-2 infection, and the development of high-grade cervical squamous intraepithelial lesions (HSILs) in(More)
BACKGROUND The efficacy of various antiretroviral (ARV) therapy regimens for human immunodeficiency virus type 2 (HIV-2) infection remains unclear. HIV-2 is intrinsically resistant to the nonnucleoside reverse-transcriptase inhibitors and to enfuvirtide and may also be less susceptible than HIV-1 to some protease inhibitors (PIs). However, the mutations in(More)
We sought to identify factors associated with delayed diagnosis of human immunodeficiency virus (HIV; testing HIV-seropositive 6 months or more after HIV seroconversion), by comparing delayed testers to non-delayed testers (persons who were diagnosed within 6 months of HIV seroconversion), in King County, Washington among men who have sex with men (MSM).(More)
Lactobacillus acidophilus has been reported to be the predominant vaginal species. Vaginal lactobacilli isolated from 215 sexually active women were identified using whole-chromosomal DNA probes to 20 American Type Culture Collection Lactobacillus strains. Most women were colonized by L. crispatus (32%), followed by L. jensenii (23%), a previously(More)
