Sinonasal papilloma is a common benign epithelial tumor of the sinonasal tract and accounts for 0.5% to 4% of all nasal tumors. The etiology of sinonasal papilloma remains unclear, although human papilloma virus has been proposed as a major risk factor. Other etiological factors, such as anatomical variations of the nasal cavity, may be related to the pathogenesis of sinonasal papilloma, becaus...

OBJECTIVES The aim of the present study was to assess the prevalence of Herpes Simplex virus, Epstein Barr virus and Human Papilloma virus -16 in oral lichen planus cases and to evaluate whether any clinical variant, histopathological or demographic feature correlates with these viruses. STUDY DESIGN The study was conducted on 65 cases. Viruses were detected immunohistochemically. We evaluate...

Twelve neonate calves were repeatedly challenged with bovine papilloma virus. All calves were initially susceptible to bovine papilloma virus and complete resistance to challenge occurred after the onset of fibroma regression. Fibroma regression was not correlated with serum antibody titers to bovine papilloma virus as measured by an immunodiffusion assay. Fibroma regression occurred prior to t...

Thirty seven cases of oesophageal squamous cell carcinoma were studied by applying DNA slot blot analysis and in situ hybridisation using type specific probes for HPV 6, 11, 16 and 18. Cases of condyloma accuminata, cervical carcinoma, and laryngeal papilloma were used as controls. Blocks including areas of invasive carcinoma, intraepithelial neoplasia, and normal epithelium were studied in eac...

In the present study we describe sandwich design hybridization probes consisting of magnetic particles (MP) and quantum dots (QD) with target DNA, and their application in the detection of avian influenza virus (H5N1) sequences. Hybridization of 25-, 40-, and 100-mer target DNA with both probes was analyzed and quantified by flow cytometry and fluorescence microscopy on the scale of single part...

High-risk human papilloma virus (hrHPV) plays an important role in cervical cancer. The aim of this study was to investigate the distribution HPV genotypes region and correlate it with liquid-based-cytology (LBC) colposcopic biopsy results. Furthermore, potential relationship between infections bacterial vaginosis (BV) investigated. were determined using real-time PCR. LBC, biopsies, BV examina...

Herpes B virus DNA was specifically amplified by PCR, targeting the regions that did not cross-react with herpes simplex virus (HSV). The amplified products, which were shown to be highly genetic polymorphisms among herpes B virus isolates, were identified by microplate hybridization with probes generated by PCR. The products immobilized in microplate wells were hybridized with the biotin-label...
