To locate the genes controlling adaptability in bread wheat using AMMI (additive main effect and multiplicative interaction) model, twenty-one substitution lines derived from the parents Chinese Spring (recipient) and Chayan (donor) were used in a randomized complete block design with three replications in three different environments in the Agricultural College of Razi University, Kermanshah, ...

Background and Aims: The cytochrome P450 1A1 (CYP1A1) plays a curial role in phase I metabolism of polycyclic aromatic hydrocarbons to their ultimate biologically active intermediates that have potential reproductive toxicity in men. Reproductive functions in men may be impaired by many environmental, physiologic, and genetic factors. The majority of the environmental factors are xenobiotics. M...

reactions of 1 ,zdihydropyridines (la-c) and 1,4-dihydropyridines (2a-c) in the presence of benzyne (3) under thermal conditions, and in the case of (2c) under photochemical conditions, have been investigated. benzyne acts as an oxidizing agent to convert dihydropyridine (la) and (2a) to the corresponding pyridine (4) or adds as a dienophile to (lb-c).

background: canine parvovirus (cpv) infection is one ofthe most common causes of infectious gastroenteritis in dogs andis a highly contagious, often fatal disease. the original virus(cpv type 2) has had some mutations since its emergence andnew variants (cpv-2a, 2b and 2c) have been reported from manycountries all around the world. early diagnosis and treatment canprofoundly affect the disease ...

background egypt has one of the highest (16-8%) prevalence rates of hcv infection in the world. approximately 90% of egyptian hcv isolates belong to a single subtype (4a), which responds less successfully to interferon therapy than other subtypes. studies comparing the efficacy and safety of pegifn alfa-2a and pegifn alfa-2b in treatment-naive hcv-infected patients have shown conflicting result...

conclusions there was no significant difference in the efficacy of peginterferon-alpha-2a and peginterferon-alpha-2b in iranian patients. physicians might choose the treatment regimen for every individual concerning the differences in side effects of peginterferons. background nearly 0.5% of iranians are infected with hcv. peginterferon-alpha-2a and peginterferon-alpha-2b are the two available ...

Background: Hepatitis C virus (HCV) infection is the most common transfusion transmitted disease in poly-transfused patients worldwide. In this study we aimed to evaluate the effects of pegylated interferon alfa-2a (PEG-IFN A-2a) in reducing serum ALT and eradicating serum hepatitis C virus (HCV) RNA in HCV infected polytransfused thalassemic patients. Materials and Methods: A cohort of 51 HCV-...
