1. Alterations in the expression and activity of extracellular matrix components in HPV-associated infections and diseases
Infection with human papillomaviruses is associated with a series of benign and malignant hyperproliferative diseases that impose a heavy burden on human populations. A subgroup of mucosal human papillomavirus types are associated with the majority of cervical cancers and a relevant fraction of vulvar, vaginal, anal, penile and head and neck carcinomas. Huma

2. Epidemiology and biology of cutaneous human papillomavirus
Cutaneous human papillomaviruses (HPVs) include β- and γ-HPVs, in addition to a small fraction of α-HPVs. β-HPVs were first isolated from patients with the rare genetic disorder Epidermodysplasia verruciformis, and they are associated with the development of nonmelanoma skin cancer at sun-exposed skin sites in these individuals. Organ transplant recipien

3. Epidemiology of oral HPV in the oral mucosa in women without signs of oral disease from Yucatan, Mexico
High-risk human papillomaviruses (HR-HPV) are considered necessary for the development of cervical cancer. Furthermore, there is no doubt that some types of oral squamous cell carcinoma are associated with HR-HPV. The epidemiology of oral HPV infections in healthy subjects remains unclear due to a lack of knowledge. The objective of this study was to investi

4. Enhanced anti-tumor effect of a gene gun-delivered DNA vaccine encoding the human papillomavirus type 16 oncoproteins genetically fused to the herpes simplex virus glycoprotein D
Anti-cancer DNA vaccines have attracted growing interest as a simple and non-invasive method for both the treatment and prevention of tumors induced by human papillomaviruses. Nonetheless, the low immunogenicity of parenterally administered vaccines, particularly regarding the activation of cytotoxic CD8+ T cell responses, suggests that further improvements

5. Identificação e estudo da diversidade do papilomavírus associado a lesões cutâneas em bovinos
Papillomaviruses (PV) has a worldwide distribution and is recognized as an etiologic agent associated with several benign and malignant epithelia lesions in human and animals. The Papillomaviridae family is a highly heterogeneous group of viruses, which has 18 genera, and likely occurs in most mammals and birds. The PV genome is circular double-stranded DNA

6. Prevalence of Human Papillomaviruses - HPV in women wich were atended in SAE in Cacoal City, between 2003 and 2005 / Prevalência do papilomavírus humano - HPV em mulheres atendidas no serviço de atendimento especializado, no município de Cacoal - RO, no período de 2003 a 2005
Population subjected to poor life conditions are more vulnerable, because the social, cultural and economical inequality influence directly on the population process of becoming sick and dying, as, the Sexually Transmitted Diseases (STDs) are among the more common disease causes in the world and bring sanitary, social and economical nature consequence being

7. Study on the prevalence of human papillomavirus and clinical and histological aspects in chronic actinic cheilitis. / "Estudo da prevalência do papilomavirus humano e dos aspectos clínicos e histológicos na queilite actínica crônica"
The oncogenic human papillomaviruses (HPVs) are important agents in the etiology of gynecological cancer and have been recently related to some premalignant lesions and to some types of mouth cancer. In order to evaluate the relation between HPVs and one type of precancerous lesion that affects the lips called chronic actinic cheilitis (CAC), 29 CAC patients

8. Infection with human papillomaviruses of sexual partners of women having cervical intraepithelial neoplasia
Epidemiological studies show that human papillomaviruses (HPV) are strongly related to cervical cancer and cervical intraepithelial neoplasias (CIN). Unlike the case for women, there are no consistent data on the natural history of HPV in the male population even though these viruses are prevalent in males. We carried out a prospective study to assess the pr

9. Healthy Skin of Many Animal Species Harbors Papillomaviruses Which Are Closely Related to Their Human Counterparts
Papillomaviruses associated with clinical symptoms have been found in many vertebrate species. In this study, we have used an L1 gene consensus PCR test designed to detect a broad spectrum of human skin papillomaviruses to analyze swab samples from healthy skin of 111 animals belonging to 19 vertebrate species. In eight of the species, papillomavirus DNA was

10. Epidermodysplasia verruciformis associated human papillomaviruses present a subgenus-specific organization of the regulatory genome region.
The regulatory regions of the human papillomaviruses (HPVs) 9, 17, 20, and 36 were mapped, sequenced, and aligned. They revealed an arrangement of putative protein binding sites specific for the epidermodysplasia verruciformis associated HPVs. Three subgroups could be differentiated.

11. Evolution of human papillomavirus type 18: an ancient phylogenetic root in Africa and intratype diversity reflect coevolution with human ethnic groups.
Papillomaviruses are an ideal model system for the study of DNA virus evolution. On several levels, phylogenetic trees of papillomaviruses reflect the relationship of their hosts. Papillomaviruses isolated from remotely related vertebrates form major branches. One branch of human papillomaviruses (HPVs) includes an ape and two monkey papillomaviruses, possib

12. The Ubiquity and Impressive Genomic Diversity of Human Skin Papillomaviruses Suggest a Commensalic Nature of These Viruses
Human papillomaviruses (HPV) are epitheliotropic viruses, with some types suggested to be associated with skin cancer. In this study, swab samples collected from five different sites on the skin of renal transplant recipients, dialysis patients, and age- and sex-matched healthy controls were analyzed for HPV DNA by a newly designed PCR test. Most individuals
