Background: Progesterone is indispensable for differentiation of human endometrial stromal cells (HESCs) into decidual cells, a process that critically controls embryo implantation. However, HESCs also abundantly express androgen receptors (AR), yet the role of this member of the superfamily of ligand-dependent transcription factors in the decidual process remains poorly elucidated. Materials a...
The reduction of {ArFeBr}(2) (Ar = terphenyl) with KC(8) in the presence of excess PMe(3) afforded the Fe(i) complex 3,5-Pr(i)(2)-Ar'Fe(PMe(3)) (1) (Ar'-3,5-Pr(i)(2) = C(6)H-2,6-(C(6)H(3)-2,6-Pr(i)(2))-3,5-Pr(i)(2)), which has a structure very different from the previously reported, linear Cr(i) species 3,5-Pr(i)(2)-Ar*Cr(PMe(3)) (3,5-Pr(i)(2)-Ar* = C(6)H-2,6-(C(6)H(2)-2,4,6-Pr(i)(3))(2)-3,5-Pr...
we consider two commutativity ratios $pr(g)$ and $f(g)$ in a finite group $g$ and examine the properties of $g$ when these ratios are `large'. we show that if $pr(g) > frac{7}{24}$, then $g$ is metabelian and we give threshold results in the cases where $g$ is insoluble and $g'$ is nilpotent. we also show that if $f(g) > frac{1}{2}$, then $f(g) = frac{n+1}{2n}$, for some na...
In Arabidopsis, NPR1 mediates the salicylic acid (SA)-induced expression of pathogenesis-related (PR) genes and systemic acquired resistance (SAR). Here, we report the identification of another component, CPR 6, that may function with NPR1 in regulating PR gene expression. The dominant CPR 6-1 mutant expresses the SA/NPR1-regulated PR genes (PR-1, BGL 2, and PR-5) and displays enhanced resistan...
The two, nearly identical, isoforms of human progesterone receptors (PR), PR-B and -A, share activation functions (AF) 1 and 2, yet they possess markedly different transcriptional profiles, with PR-B being much stronger transactivators. Their differences map to a unique AF3 in the B-upstream segment (BUS), at the far N terminus of PR-B, which is missing in PR-A. Combined mutation of two LXXLL m...
The protease (PR) of Murine leukemia virus (MLV) was expressed in Escherichia coli, purified to homogeneity and characterized by using various assay methods, including HPLC-based, photometric and fluorometric activity measurements. The specificity of the bacterially expressed PR was similar to that of virion-extracted PR. Compared with human immunodeficiency virus type 1 (HIV-1) PR, the pH opti...
این مطالعه به منظور برآورد میزان تنوع ژنتیکی در جمعیت لاین های مختلف جوجه های گوشتی آرین انجام گرفت. برای انجام این تحقیق200 نمونه خون از هر دو جنس (نر و ماده) در هر یک از جمعیت های a، b، c و d به تعداد 50 نمونه از هر لاین جمع آوری شد. نمونه های خون با حفظ زنجیره سرد به آزمایشگاه منتقل و استخراج dna به روش نمکی بهینه یافته انجام پذیرفت. برآورد تنوع ژنتیکی به کمک 20 نشانگر rapd و با استفاده از و...
The granular Gd1-x-zPrxCazBa2Cu3O7-δ high-temperature cuprate samples with 0.0 ≤ x ≤ 0.3 and 0.0≤ x ≤ 0.35 are prepared by standard solid state reaction and characterized by XRD and SEM techniques. The BaCuO2 and impurity phases are less than 1% in the samples having high levels of pr and Ca concentrations. The electrical resistivity measurements show a nonlinear reduction in Tc(x,z=etc) vers...
BACKGROUND The pathology of diabetic neuropathy involves oxidative stress on pancreatic β-cells, and is related to decreased levels of Insulin-like growth factor 1 (IGF-1). Acylated steryl β-glucoside (PR-ASG) found in pre-germiated brown rice is a bioactive substance exhibiting properties that enhance activity of homocysteine-thiolactonase (HTase), reducing oxidative stress in diabetic neuropa...
