1. Update on human papilloma virus - part I: epidemiology, pathogenesis, and clinical spectrum,,
Abstract Infection with human papilloma virus (HPV) is related to a great number of cutaneous and mucosal manifestations. The spectrum of HPV ranges from inapparent infections, through various clinical benign presentations including cutaneous and mucosal disease, to malignant and premalignant conditions. New HPV types are currently described in the literatur

2. Uncommon non-oncogenic HPV genotypes, TP53 and MDM2 genes polymorphisms in HIV-infected women in Southern Brazil
Background:It is believed that Human Papillomavirus (HPV) and Human Immunodeficiency Virus coinfection contributes to increase the risk for cervical intraepithelial injuries. Several factors may contribute to cervical cancer (CC) development, including genetic variants such as TP53and MDM2 gene polymorphisms.Materials and methods:A hundred HIV-infected women

3. Prevalence of human papillomavirus infection, distribution of viral types and risk factors in cervical samples from human immunodeficiency virus-positive women attending three human immunodeficiency virus-acquired immune deficiency syndrome reference centres in northeastern Brazil
Human immunodeficiency virus (HIV)-positive patients have a greater prevalence of coinfection with human papillomavirus (HPV) is of high oncogenic risk. Indeed, the presence of the virus favours intraepithelial squamous cell lesion progression and may induce cancer. The aim of this study was to evaluate the prevalence of HPV infection, distribution of HPV ty

4. Presence of highly oncogenic human papillomavirus in the oral mucosa of asymptomatic men
OBJECTIVES: The aim of this study was to identify highly oncogenic forms of human papillomavirus in the oral mucosa of asymptomatic men. METHODS: In this study, we analyzed samples of exfoliated cells from the oral cavity of 559 asymptomatic men. DNA-human papillomavirus was detected using the consensus primers PGMY09/11; viral genotyping was performed

5. Human papillomavirus infection among sexual partners attending a Sexually Transmitted Disease Clinic in Rio de Janeiro, Brazil
Cervical cancer is a major source of illness and death among women worldwide and genital infection with oncogenic human papillomavirus (HPV) its principal cause. There is evidence of the influence of the male factor in the development of cervical neoplasia. Nevertheless, the pathogenic processes of HPV in men are still poorly understood. It has been observed

6. Interação de oncoproteínas virais E6 e E7 de HPV16/18 com alvos celulares potenciais para o desenvolvimento de estratégias terapêuticas. / Interaction of E6 and E7 viral oncoproteins of HPV16/18 with potential cellular targets to the development of therapeutic strategies.
O potencial oncogênico do papilomavírus humano (HPV) baseia-se na capacidade das oncoproteínas virais E6 e E7 alterarem o ciclo celular, levando à imortalização e malignidade das células. O importante papel das oncoproteínas na progressão tumoral e na interação com inúmeros alvos celulares tem relevância em estudos para o desenvolvimento de vaci

7. Nível de evidência acerca da eficácia das vacinas disponíveis contra a infecção pelo vírus HPV: revisão sistemática / Level of evidence about the efficacy of available vaccines against HPV infection: systematic review
Annually, about 500,000 new cases of cervical cancer occur and nearly 230,000 women die worldwide affected by this cancer, with particular emphasis on developing countries. Persistent HPV infection is a necessary condition for the occurrence of this disease and the oncogenic types HPV 16 and HPV 18 are responsible for approximately 70% of cervical cancer cas

8. Caracterização molecular do Epstein-Barr vírus (EBV) em pacientes portadores de HIV, em tratamento, atendidos no sistema hospitalar do sistema penitenciário do Estado de São Paulo. / Molecular characterization of Epstein-Barr virus (EBV) in HIV patients in treatment from the hospitalar system in the penitentiary system from São Paulo State, Brazil.
The Epstein-Barr Virus (EBV) is the only species to the genus Lymphocriptovirus that infects humans. One of the possible route for its transmission thought by contamined saliva and usually occurs in the childhood. This study analysed 165 clinical samples from HIV infected patients, treated by HARRT, attended in the Hospitalar System in the Penitentiary Syste

9. Desenvolvimento de estratégias vacinais contra tumores induzidos pelo vírus do papiloma humano tipo 16 (HPV-16) baseadas em linhagens geneticamente modificadas de Bacillus subtilis. / Development of vaccine strategies against tumors induced by human papiloma virus type 16 (HPV-16) based on genetically modified Bacillus subtilis strains.
Bacillus subtilis é uma bactéria gram-positiva, não patogênica, formadora de esporos e com um grande conhecimento disponível a cerca de sua genética e fisiologia, comparável apenas à Escherichia coli K12. Recentemente, linhagens geneticamente modificadas de B. subtilis foram utilizadas como veículos vacinais mas, até o momento, não se havia avalia

11. Avaliação da resposta clínica e imunológica local de pacientes com neoplasia intra-epitelial cervical graus II e III tratadas com interferon alfa-2b intralesional.
Introduction: HPV is a DNA virus of tape double which can infect the lower genital tract. Its persistence, especially with oncogenic types is highly associated with the development of the high-grade squamous intraepithelial lesions. Treatment of these lesions is usually excisional (cold conization, laser conization, diathermic conization) and some studies ha

12. 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
