conclusions this study showed that cccdna can be detected in the plasma specimen of 17.9% of iranian treatment-naive patients with chronic hepatitis b infection. therefore, designing prospective studies focusing on the detection of cccdna in these patients would provide more information. results the mean (sd) age of the patients was 41.1 ± 12.4 years (range, 20 - 62 years). from a total of 106 ...

the main objective of the present work was to synthesis polyamide 6 through anionic polymerization of ε-caprolactam in an internal mixer. the reaction time and the rheological properties of samples during the polymerization were studied. the samples were characterized by thermo gravimetry analysis (tga), differential scanning calorimeter (dsc) and ft-ir spectrometer. the melt flow behavior and ...

conclusions simpleprobe® real-time pcr is a fast and accurate technique qualified to detect vkorc1 and cyp2c9 snps. these results encourage taking further steps towards using vkorc1 and cyp2c9 allelic screening to prevent clinical complications due to resistance or sensitivity to warfarin as well as anti-coagulant dose adjustment. results the allelic frequencies for vkorc1 c1173t (cc, ct, tt) w...

conclusions the quite sensitive in-house taqman real time rt-pcr assay was able to detect and quantify all four main hcv genotypes prevailing around all geographical regions of iran. results the lower limit detection of this in-house hcv real-time rt-pcr was determined as 100 rna copies/ml. inter- and intra-assay coefficient of variation (cv) of this in-house hcv real-time rt-pcr ranged from 0....
