Pregnancy-associated plasma protein-A and -A2 (PAPP-A and -A2) are proteases that cleave insulin-like growth factor-binding proteins (IGFBPs), resulting in local activation of IGF signaling pathways. Here, we examined PAPP-A and -A2 mRNA and protein levels in placenta and maternal sera from women with pre-eclampsia and compared them with samples from uncomplicated pregnancy. PAPP-A2 but not PAP...
Pregnancy-associated plasma protein A2 (PAPP-A2, also known as pappalysin-2) is a large metalloproteinase that is known to be required for normal postnatal growth and bone development in mice. We here report the detection of zebrafish papp-a2 mRNA in the chordamesoderm, notochord and lower jaw of zebrafish (Danio rerio) embryos, and that papp-a2-knockdown embryos display broadened axial mesoder...
نجم آباد در جنوب شهر گناباد، استان خراسان رضوی، و در شمال بلوک لوت واقع شده است. دو مجموعه گرانیتوییدی سری ایلمنیت به سن ژوراسیک و سری مگنتیت به سن ترشیری در منطقه شناسایی شدند. هدف از این مطالعه تعیین سن دقیق و بررسی پتروژنز توده های سری مگنتیت است. بر اساس سن سنجی به روش u-pb در کانی زیرکن، سن توده های مونزونیتی منطقه نجم آباد معادل 9/39 میلیون سال (ائوسن میانی) است. این توده ها عمدتاً ماهیت م...
Commercial microcolumns introduced in 1976 by Helena Laboratories ("Hb A2 Quik Column") and by Isolab, Inc. ("Quik-Sep") provide a rapid, simple, accurate method for quantitation of hemoglobin A2 (Hb A2). However, these kits cannot be used for the quantitation of Hb A2 in the presence of slow-moving variants such as Hb S. Recently, Isolab, Inc., produced a new kit ("Quik-Sep Improved Hb A2 Test...
As compared with the vigorous T cell response normally observed against allogeneic MHC molecules, T cells recognize xenogeneic MHC molecules poorly. To define structural features of the MHC molecule important for such species-specific recognition, HLA-A2(A2)-specific murine CTL were examined for their recognition of transfected cell lines expressing the class I molecules A2 or A2/H-2Kb(A2/Kb). ...
Human pulmonary surfactant protein A (SP-A) is encoded by two genes, SP-A1 and SP-A2, that exhibit coding sequence (allelic) and 5' splicing variability. In this report we determine the effect of the genetic variability within the SP-A1 and SP-A2 genes on the level of SP-A mRNAs and on the SP-A2 splicing variants in different individuals. We analysed mRNA specimens from 23 unrelated adults usin...
Calcium dependent phospholipase A2 activity in the mixed micelles of 1-palmitoyl-2-oleoyl-phosphatidylglycerol and cholate was measured in sera of 39 patients with Crohn's disease, 40 patients with ulcerative colitis, and 40 healthy controls. The phospholipase A2 activity was significantly raised in those sera of the patients with active Crohn's disease and those with moderate and severe ulcera...
hnRNP A2/B1 proteins are among the most abundant pre-mRNA-binding proteins of vertebrates and structurally similar to hnRNP A1. We have produced two specific monoclonal antibodies against A2 and B1 and studied their molecular characteristics and in vivo expression in rat tissues. Immunoprecipitation demonstrated that the hnRNP A2/B1 complexes contain many snRNP (small nuclear ribonucleoprotein)...
Cyclin A2 is a key player in the regulation of the cell cycle. Its degradation in mid-mitosis depends primarily on the ubiquitin-proteasome system (UPS), while autophagy also contributes. However, a fraction of cyclin A2 persists beyond metaphase. In this work, we focus on cyclin A2-rich foci detected in mitosis by high resolution imaging and analyse their movements. We demonstrate that cyclin ...
(2)1 For every real number a such that 1 ≤ a holds a ≤ a2. (3) For every real number a such that −1 ≥ a holds −a ≤ a2. (4) For every real number a such that −1 > a holds −a < a2. (5) For all real numbers a, b such that b2 ≤ a2 and a ≥ 0 holds −a ≤ b and b ≤ a. (6) For all real numbers a, b such that b2 < a2 and a ≥ 0 holds −a < b and b < a. (7) For all real numbers a, b such that −a ≤ b and b ≤...
