High-risk human papillomaviruses (HPV) cause cancer at multiple distinct anatomical locations. Regardless of the tissue of origin, most HPV positive (HPV+) cancers show highly upregulated expression of the p16 product of the cyclin-dependent kinase inhibitor 2A (CDKN2A) gene. Paradoxically, HPV+ tumor cells require continuous expression of this tumor suppressor for survival. Thus, restoration o...

PURPOSE To report the identification of human papillomavirus types in four cases of conjunctival papillomas and to review the literature regarding human conjunctival papillomavirus (HPV). METHODS Specimens from conjunctival papillomas of four patients were analyzed for the presence of HPV by polymerase chain reaction and subsequent filter hybridization. HPV types 6, 11, 16, 18, 31, and 33 wer...

background: cervical cancer has been shown to be highly associated with human papillomavirus (hpv) infection. the viral oncogenes e6 and e7 are constantly expressed by the tumor cells and are therefore potent targets for therapeutic genetic vaccination. in the present study, it was investigated the potential effect of hpv-16 e6, e7 and l1 co-administration to activate specific cytotoxic t lymph...

Human papillomavirus (HPV) infection is known to play a fundamental role in cervical and other ano-genital human cancers. The recent identification of HPVs in human breast tumors and the immortalization of normal breast cancer cells by HPV high risk types 16 and 18 suggest that the virus could be implicated in the pathogenesis of human mammary tumors. In this study, we investigated the presence...

Background: Condyloma acuminata (CA) is a sexually transmitted infection (STI) caused by human papillomavirus (HPV), especially types 6 and 11. The number of HPV infections increases in immunosuppressed conditions, such as immunodeficiency virus (HIV) infection. Risk factors CA patients gender, sexual partner, orientation, intercourse can increase HIV status.

Background/Purpose: HPV vaccine is critical in the primary prevention of infection and related diseases. vaccination alone reduces by 70% cervical cancer 48%. Healthcare workers are expected to have sufficient knowledge positive attitudes behaviours about vaccine. This study aimed determine level healthcare their beliefs barriers towards vaccination. 
 Methods: In this cross-sectional stud...

background: cervical cancer is one of the most common types of women’s reproductive cancers. a major risk factor for cervical cancer is exposure to a group of common sexually transmitted viruses called human papillomavirus  (hpv). the over expression of hpv 16 i.e., e6 antigen in the tumors of suspected cervical cancer tissues. however e-6 antigen has hyaluronan binding protein site. methods: t...

human papilloma virus (hpv) is considered as the main sexually transmitted etiological agent for the cause and progression of preneoplastic cervical lesions to cervical cancer. this study is discussing the prevalence of hpv and its genotypes in cervical lesions and invasive cervical cancer tissues and their association with various risk factors in women from varanasi and its adjoining areas in ...
