we have reviewed the medical records of 40 patients with disseminated (bacille calmette-guerin) bcg from 1996 to 1999 in the immunology department of the children hospital, medical center, tehran university. these patients are divided in to 3 groups: 1. patients who had disseminated (bacille calmette-guerin) bcg after vaccination and their diagnosis was chronic granulomatous disease. 2. patient...

objective(s) previous studies have demonstrated that the nitric oxide (no) dependent death of murine peritoneal macrophages activated in vitro with ifn-g and lps is mediated through apoptosis. in the present study, we investigated the synergistic effect of lps, ifn-g and iron on no production and apoptosis. materials and methods after determination of iron cytotoxicity, the peritoneal macrophag...

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...

background previous studies using pegylated interferon (peg-ifn) and ribavirin (rbv) combination therapy suggested that patients with hepatitis c virus (hcv) genotype 1 and low pretreatment hcv rna level who achieved rapid virological response (rvr) can be treated for 24 weeks without compromising sustained virological response (svr) rate. objectives the current study aimed to investigate the e...

conclusions our study showed no correlation between rs12979860 and rs8099917 snps and chronic hbv infection. further studies, with larger sample sizes and different ethnicities, are necessary to validate our findings. objectives this study was carried-out to investigate the association of ifnl3 gene polymorphisms (rs12979860 and rs8099917) with hbv susceptibility, in chronic hbv-infected patien...

background the hepatitis c virus (hcv) infection has been identified as a leading cause of progressive liver diseases worldwide. despite new treatment strategies, pegylated interferon alfa-2a (peg-ifnα-2a), in combination with ribavirin (rbv), still represents the gold standard of therapy for hepatitis c in developing countries. results in this study, a significant association was observed betw...

interferon regulatory factor 7 (irf7) gene was cloned from a subtractive cdna library constructed with mrnas obtained from rainbow trout (oncorhynchus mykiss) macrophage cell line (rts-11). using expressed sequence tag clones of submitted irf7 amino acid sequences, specific primers were designed. results showed that irf7 cdna contains an orf of 1251 nucleotides that translates into a 416 residu...

objective: despite availability of an effective vaccine against hepatitis b virus (hbv), the global prevalence of this virus infection has not diminished significantly. contrary to numerous other human viruses, hbv does not have the ability to propagate in cell culture. however, infectious virus has been produced by transfection of human hepatoma cells with plasmids that contain full length hbv...

the aggregation of protein is the most prevalent and the most disturbing kind of instability and this challenge exists in almost every stage of the development of protein drug. the presence of insoluble aggregations in protein drugs will make the supply of the product a tough job. this study identifies the inhibition of the folded interferon beta 1-b’s aggregation with the assistance of some ex...
