Brassinosteroid (BR)-induced antioxidant defence has been shown to enhance stress tolerance. In this study, the role of the maize 65 kDa microtubule-associated protein (MAP65), ZmMAP65-1a, in BR-induced antioxidant defence was investigated. Treatment with BR increased the expression of ZmMAP65-1a in maize (Zea mays) leaves and mesophyll protoplasts. Transient expression and RNA interference sil...
The human transcription factor EF-1A binds to the purine-rich E1A core enhancer sequence in the adenovirus E1A and E4 and polyomavirus enhancer regions. The consensus binding site for EF-1A resembles that of members of the ets domain protein family. EF-1A activation of transcription requires a dimeric binding site. Analysis of binding sites containing point mutations revealed that EF-1A binding...
oxidative addition reactions of 1,4-diiodo-butane and 1,3-diiodo-propane with [ptme2(ph2phen)]; in which ph2phen=4,7-diphenyl-1,10-phenanthroline, were studied in different solvents such as acetone and benzene.oxidative addition reaction of [pt me2(ph2phen)] with i(ch2)4i and i(ch2)3i produced the [pt me2i(ch2)4(ph2phen)i] (1a) and [pt me2i(ch2)3(ph2phen)i] (1b).all the platinum (iv) products w...
Results from recent studies have shown that alpha(1A)-adrenergic receptor (alpha(1A)-AR) antagonists could offer a new alternative in the treatment of preterm delivery. However, members of this group [2-(2,6-dimethoxyphenoxyethyl)aminomethyl-1,4-benzodioxane hydrochloride (WB4101), 5-methylurapidil (5-MU)] are known to influence serotonin (5-hydroxy-tryptamine) (5-HT(1A)) receptors, too. Our ob...
سابقه و هدف: بیماری های قلبی - عروقی شایع ترین علل مرگ و میر در جهان و ایران هستند.sdf-1a به عنوان یک کموکین موثر در کاهش التهاب و آسیب، در آنژیوژنز نیز نقش دارد. این مطالعه به بررسی مقایسه ای سطح سرمی این کموکین در مبتلایان به سکته قلبی و افراد سالم بر اساس سن و جنس پرداخته است.مواد و روش ها: این مطالعه مورد - شاهدی در دو گروه 63 نفری شامل یک گروه مبتلا به سکته قلبی و گروه دیگر افراد غیرمبتلا ...
Abstract Background and Objectives Following incompatible blood transfusions, anti-HLA and anti- HPA antibodies may develop and cause various disorders such as post-transfusion purpura, platelet refractoriness, and thrombocytopenia leading to bleeding. The aim of this study was to investigate platelet antigens and antibodies in multi-transfused patients. Materials and Methods In this desc...
Macrophage inflammatory protein-1a (MIP-1a) is a member of the chemokine family of proinflammatory mediators. In addition to its inflammatory roles, MIP-1a has been shown to be active as an inhibitor of primitive hemopoietic cell proliferation. Indeed, a dysfunction in this inhibitory process has been postulated to contribute to leukemogenesis. Research has been aimed at characterizing the rece...
Diphenyldiazomethane with four iodine groups at the ortho positions and two tert-butyl groups at the para positions, i.e., bis(4-tert-butyl-2,6-diiodophenyl)diazomethane (1a-N₂), was synthesized as a sterically hindered triplet carbene precursor. Irradiation of 1a-N₂ in solution effectively generated the corresponding triplet diphenylcarbene ³1a, which was characterized by UV-vis spectroscopy a...
Brome mosaic virus (BMV), a positive-strand RNA virus in the alphavirus-like superfamily, encodes two RNA replication proteins. The 1a protein has putative helicase and RNA-capping domains, whereas 2a contains a polymerase-like domain. Saccharomyces cerevisiae expressing 1a and 2a is capable of replicating a BMV RNA3 template produced by in vivo transcription of a DNA copy of RNA3. Although ins...
Abstract: Genotyping of the hepatitis C virus (HCV) is important for designing therapeutic strategies and regional specific diagnostic assays. The aim of this study was to identify the HCV genotypes in HCV infected blood donors. This is the first report on HCV genotypes in blood donors in Iran. In this cross-sectional study, 103 blood donors with hepatitis C were investigated for HCV genotype...
