PURPOSE The aim of this study was to evaluate the human papillomavirus genotypes and the frequency of multiple human papillomavirus infections, as well as to assess the association between human papillomavirus genotype, cyto-histopathological abnormalities and age range. METHODS A retrospective cross-sectional study was carried out between June 2010 and October 2013 in Salvador, Bahia, Brazil...

We conducted a cross-sectional analysis to assess the distribution of human papillomavirus (HPV) types and explored an acceptable strategy for cervical screening in Shenzhen, China. A total of 2717 individuals ranging in age from 30-59 years were recruited. Clinical sensitivity and specificity as well as positive (PPV) and negative (NPV) predictive values were estimated. A triage strategy was r...

BACKGROUND We describe the incidence and duration of cervical human papillomavirus (HPV) infection episodes along with the risk of infection reappearance following a period of nondetection. METHODS Women (1,788) ages 16 to 23 years underwent cytologic testing and PCR-based testing of cervical swab samples for HPV DNA (HPV-16/18/31/33/35/45/52/58/59) at approximately 6-month intervals for up t...

Human Papillomaviruses are viruses that infect the epithelial layers of the oral, rectal, vaginal, and cervical mucosa. There is a causal link between the development of cervical cancer and some other cancers and high-risk human papillomavirus infection (1, 2). Currently there is no prophylactic or therapeutic vaccine available against human papillomavirus infection and its associated lesions. ...

Human papillomavirus (HPV) is a significant health care burden in the United States. The majority of sexually active men and women will be infected with HPV at some point in their lives and are subject to developing human papillomavirus-associated disease. Current estimates suggest that 20 million Americans are currently infected, and more than 5 million new infections occur each year. The prev...

Cervical cancer remains the fourth most common cause of cancer-related deaths in women worldwide, and human papillomavirus infection represents the most important risk factor for the development of cervical cancer. Minichromosome maintenance protein-2 has been previously identified by DNA microarray and transcriptional profiling as genes that is overexpressed in cervical carcinomas. 183 cases w...

Human papillomaviruses cause the most common sexually transmitted infection in the world and are responsible for nearly all cases of cervical cancer. Genital human papillomavirus infection can be divided into low-risk infections (causing genital warts) and high-risk infections (causing cervical intraepithelial neoplasia, and cervical and other cancers). Exposure to human papilloma- virus typica...

  Objective(s):  Infection by high-risk papillomavirus is regarded as the major risk factor in the development of cervical cancer. Recombinant DNA technology allows expression of the L1 major capsid protein of HPV in different expression systems, which has intrinsic capacity to self-assemble into viral-like particles (VLP). VLPS are non-infectious, highly immunogenic and can elicit neutralizing...

Real-time type-specific multiplex human papillomavirus (HPV) PCR assays were developed to detect HPV DNA in samples collected for the efficacy determination of the quadrivalent HPV (type 6, 11, 16, and 18) L1 virus-like particle (VLP) vaccine (Gardasil). Additional multiplex (L1, E6, and E7 open reading frame [ORF]) or duplex (E6 and E7 ORF) HPV PCR assays were developed to detect high-risk HPV...

Human papillomavirus (HPV) replication occurs in terminally differentiating epithelium, and requires the activation of cellular DNA replication proteins. Unscheduled DNA replication can result in the induction of apoptosis, and the viral E6 protein induces the degradation of p53 to prevent this. It has recently been shown that HPV-18 E6 can also stimulate the degradation of Bak, a pro-apoptotic...
