A virus (MnPV) with the structural characteristics of papilloma viruses was isolated from benign and malignant proliferations of adult animals of the inbred line 'GRA Giessen' of Mastomys natalensis. The particles can be banded in CsCl gradients at densities of 1.34 g/ml (full particles) and 1.29 g/ml (empty particles). The virus DNA has a buoyant density of 1.7104 g/ml and can exist in three d...

Background: Neuromyelitis Optica (NMO) is an autoimmune inflammation of the central nervous system in which autoantibodies are released against Aquaporin-4 (AQP-4), astrocytic water channels. The disease is characterized by transverse myelitis and optic neuritis. Viruses could be inflammatory agents in the brain. Due to such inflammatory reactions, autoantibodies would cross the blood brain bar...

A fibrosarcoma was induced in a hamster by bovine papilloma virus type 2 (BPV2). The content of BPV2 DNA sequences was measured by DNA-DNA and cRNA-DNA hybridizations. The tumor contained approximately 300 BPV2 genome equivalents per cell. Southern blot hybridization indicated that the viral DNA was in free form, the entire genome most likely being present. In situ hybridization with BPV2 cRNA ...

abstract aims: a few studies concentrate on the level of knowledge of hpv. this study was conducted to evaluate the level of knowledge about hpv, its risk factors, and its relation with cervical cancer in women of kashan city, iran. instrument & methods: this descriptive cross-sectional study was conducted in january 2015 in the population of the women of kashan city, iran, and 200 persons were...

human papilloma virus causes benign and malignant abnormalities in different part of the body. the link between high risk types of hpv and some anogenital and aerodigestive tract cancer is well established. oral hpv infection plays a role in developing oropharyngeal squamous cell carcinoma. we studied the prevalence of oral hpv in healthy individuals and its relative risk factors.saliva samples...

purpose: to explore any association between human papilloma virus (hpv) infection and ocular surface squamous neoplasia. methods: forty pathological specimens including 20 cases of conjunctival intra-epithelial neoplasia grade i (cin i) and 20 cases of cin iii and invasive squamous cell carcinoma (scc) together with 20 pterygium samples (controls) were analyzed by polymerase chain reaction (pcr...

The ability to obtain infectious papillomavirus virions from molecularly cloned DNA has not been previously reported. We demonstrate here that viral genomes isolated from a recombinant++ DNA clone of cottontail rabbit papillomavirus (CRPV) gave rise to infectious virus when inoculated into cottontail rabbit skin. Replication occurred in papillomas that formed at inoculation sites. Extract of a ...

introduction: the human papilloma virus (hpv) can play a role in the development of head and neck squamous cell carcinoma (scc). our aim was to assess the prevalence of hpv dna in scc of the larynx. the impact of hpv infection on patient survival was also evaluated.  materials and methods: this case-control study was performed in 44 patients with scc of the larynx (case group), while the contro...
