Human papillomavirus (HPV) infection is the leading risk factor for cervical intraepithelial neoplasia (CIN) and cervical cancer. Detection of high-risk HPV infections might identify women who are at increased risk of development or progression of a cervical lesion and may have prognostic significance. Therefore there is considerable interest in identifying and accurately typing the viruses. PC...
OBJECTIVE The aim of this study was to compare and evaluate three methods of DNA extraction for the amplification of Chlamydia trachomatis in uterine cervical samples collected in PreservCyt solution. ThinPrep is the trade name for the slide preparation. METHODS Thirty-eight samples collected in LCx buffer medium, which were identified as C. trachomatis infected by ligase chain reaction (LCR)...
RNA replicon derived from Flavivirus genome is a valuable tool for studying viral replication independent of virion assembly and maturation, besides being a great potential for heterologous gene expression. In this study we described the construction of subgenomic replicons of yellow fever virus by yeast-based homologous recombination technique. The plasmid containing the yellow fever 17D strai...
Polymerase chain reaction-amplified product length polymorphism (PCR-APLP) is one of the most convenient and reliable methods for single nucleotide polymorphism (SNP) analysis. This method is based on PCR, but uses allele-specific primers containing SNP sites at the 3'-terminus of each primer. To use this method at least two allele-specific primers and one "counter-primer", which serves as a co...
Helicobacter pylori is thought to represent a significant etiopathogenic factor in diseases of the upper gastrointestinal tract. It seems, therefore, important to elaborate effective techniques for its detection. The aim of the present study was to evaluate the effectiveness of Helicobacter pylori detection using the PCR technique on paraffin sections with various pairs of primers and to compar...
PURPOSE NY-ESO-1 and LAGE-1 are homologous cancer-testis antigens, which are expressed in many different cancers. It is essential to type tumors accurately to assess patient suitability for clinical trials which target these. This study evaluates typing strategies used to distinguish these two homologous but distinct antigens and to characterize and quantitate expression of each in clinical sam...
