background three single nucleotide polymorphisms (snps) near interleukin-28b (il-28b) gene were shown to be highly associated with treatment response (svr) in patients with chronic hepatitis c virus (hcv) infection. there is limited data about the role of single and combined il-28b polymorphisms in hcv-infected polish population. objectives this study's aim was to determine predictability of th...

there are limited clinical investigations identifying the percentage of t helper 1 (th1) and t regulatory (treg) cells in stable as well as rejected kidney allografts, a concept which needs to be more studied. the aim of our study was to compare the percentage of cd4+ ifn-γ+ cells, the number of ifn-γ secreting cells and the amount of foxp3 expression in patients with or without stable graft fu...

the aim of this study was to investigate the possible influence of interferon-gamma (ifn- γ) gene polymorphism +874 (a/t) (rs2430561) in the susceptibility and renal complications of patients with henoch-schonlein purpura (hsp). we also studied the effects of ifn-γ allelic variation on serum levels of pro-and anti-inflammatory cytokines in hsp patients. the  study  population  comprised  97  pa...

background: a dinucleotide variant rs368234815 in interferon lambda 4 (ifnl4) gene was recently found to be associated with the hepatitis c virus (hcv) treatment response. this study aimed to assess the impact of ifnl4 rs368234815 polymorphism on treatment response to pegylated?ifn alpha (peg?ifn??) and ribavirin (rbv) in hemophilic patients with chronic hepatitis c (chc). materials and methods...

Rat leukocytes produce three interferon species after infection with Newcastle disease virus. Two of the three interferon species (22-24,000 and 30,000 daltons) were acid and heat stable, protected rat and mouse cells from virus-mediated cytopathic effect (CPE), and were neutralized by antisera to mouse L-cell (alpha/beta) interferon. The third, 30,000-dalton interferon species was heat and aci...

Treatment of HeLa cells with human interferons inhibited 51Cr release from cells induced by ultraviolet-inactivated Sendai virus. The inhibitory effect became apparent about 6 h after interferon treatment and persisted for 24 to 48 h. In the interferon-treated cells, the cytolysis was inhibited within 10 min after adding virus and the inhibitory action was suppressed by the treatment of the cel...

A new lymphoblastoid cell line, DG-75, was investigated for its ability to produce interferon. DG-75 cells, previously shown to be free of Epstein-Barr virus genome and receptors, could be grown in submerged culture and could produce interferon in titers comparable to interferon produced by Namalva cells. The interferon produced was similar in size to the Namalva interferon as determined by gel...

Prior to the production of human gamma interferon using recombinant DNA technology, it had been producedmainly upon mitogenic induction of lymphocytes in very low amounts, which evidently hamperedits characterization and its medical applications. The recombinant gamma interferons produced in largerquantities in prokaryotic systems retain their biological activities, and can be...

If, to be successful, a book need have but one reader, Spiro's Clinical Gastroenterology will be a megasuccess. For many will read it and all will profit. Blest with uniauthorship in an era when a case report must include even the name of the assistant resident who did the work, the style flows evenly throughout and overlap is kept to a minimum. Spiro's target is the physician who takes care of...

Investigating the Therapeutic Effect of β-Interferon and Methylprednisolone on COVID- 19 Patients’Consequence: A Non- Randomized, Double-Blinded, Controlled Study
