Objective(s) The aim of this study was to search for new antiviral agents from herbal medicines. Ethanol extracts of C. semipervirens, C. semipervirens var. horizontalis and C. semipervirens cv. Cereiformis were used in experiments to test their influence on herpes viruses (HSV-1). Materials and Methods HeLa cells monolayers were infected with herpes viruses (HSV-1). Antiviral activity of th...

background polymorphisms in the interferon λ (inf λ) genes on chromosome 19 have been associated with clearance of hepatitis c virus (hcv) induced by interferon and ribavirin therapy however there is no such data available for pakistani patients with hcv infection. objectives in this study, the effects of single nucleotide polymorphisms (snps) have been investigated in response to treatment wit...

conclusions the rvr is the strongest factor of svr and infection with hcv genotype 2 is significantly associated with rvr. neither biochemical and/or metabolic factors seem to exert influence on rvr. objectives the main aim of this study was to assess the strength of rvr, as a predictive factor of antiviral treatment response. patients and methods using univariate and multivariate analysis, we ...

conclusions our results indicated a reversible increase in rbv bioavailability after telaprevir exposure, which might be linked to the impairment of the gfr. this also suggests a rbv-telaprevir pharmacological interaction, a possible source of severe anemia observed under triple therapy. these results suggest that rbv pharmacological monitoring may be clinically relevant, especially in the cont...

objectives the current research aimed to study achillea millefolium and thymus vulgaris antiviral activity against newcastle disease virus (ndv). materials and methods the antiviral activity of the plants was measured by the reduction assay of viral titer, and explained by inhibition percentage (ip). background nowadays natural products such as pure compounds and plant extract scan provide unli...

Background and Aims: Currently, there are antiviral chemicals used to treat viral infections accompanied by limitations such as high levels of toxicity and adverse effects in humans, the emergence of drug-resistant viral strains, low numbers, and limited diversity. Therefore, it is necessary to evaluate new photochemical to obtain new therapeutic methods. The present study was conducted to eval...

results genotype b (73.6%) and genotype c (26.4%) were detected in these patients. after treatment for 12 months, the rate of hbv dna seroclearance, alt normalization, and hbeag seroconversion were significantly higher in adv group than in placebo group (p < 0.05). however, there were no significant differences in these three rates between patients infected with genotype b and c (p > 0.05). obj...

conclusions further studies on the role of hepcidin in pathogenesis of chc are needed to assess the potency of its use in antiviral treatment. results patients with chc had lower hepcidin mrna expression and more frequently iron deposits in hepatocytes than subjects with chb did. in chc group, hepcidin mrna expression was positively correlated with alanine aminotransferase activity and serum ir...
