Introduction: We wished to compare the survival benefit associated with gross total resection (GTR) in World Health Organization (WHO) grade II astrocytomas (A2) to those of grade III (A3) and grade IV (glioblastoma) astrocytomas. Methods: Using the Surveillance, Epidemiology, and End Results (SEER) Program (1999-2010) database, we identified 4,113 A2 patients. Surgical resection was defined as...
AIMS To examine the potential role of the lipolytic enzyme phospholipase A2, produced by Helicobacter pylori in ulcer formation. METHODS Phospholipase A2 activity in H pylori was compared with that in 10 commonly occurring pathogenic bacteria. Phospholipase A2 activity and its cytotoxic metabolite, lysolecithin, in the basal gastric aspirates of 12 patients infected with H pylori were compare...
Introduction: Breast cancer is the second most common cancer in the world and the most common cancer in Iranian women in terms of rate. The cytochrome P-450c17α (CYP17) gene, located on chromosome 10q24.3, encodes the enzyme cytochrome P-450c17α, which functions as a susceptibility factor in breast cancer. Material and methods: Three common polymorphisms have been described in the CYP17 gene. T...
Phenobarbital and other xenobiotics induce drug-metabolizing enzymes, including glutathione S-transferase A1/A2 (rGSTA1/A2). We examined the mechanism of induction of rGSTA1/A2 in rat livers after phenobarbital treatment. The induction of rGSTA1/A2 was not uniform across the hepatic lobule; steady-state transcript levels were threefold higher in perivenous hepatocytes relative to periportal hep...
در این کار پژوهشی از الکترود مغز مداد برای تثبیت الکتروشیمیایی و غیرالکتروشیمیایی هموگلوبین استفاده شد. کار پژوهشی حاضر شامل 4 بخش است که به ترتیب زیر می توان خلاصه کرد: الف- تثبیت الکتروشیمیایی هموگلوبین بر روی الکترود مغز مداد با اعمال پتانسیل ثابت به الکترود مغز مداد انجام گرفت. بدین ترتیب جریان آندی حاصل از اکسایش هموگلوبین تثبیت شده با غلظت هموگلوبین در محلول آن (محلول به کار رفته برای ت...
Respiratory syncytial virus (RSV) is the major cause of viral lower respiratory tract illness in children. In contrast to the RSV prototypic strain A2, clinical isolate RSV 2-20 induces airway mucin expression in mice, a clinically relevant phenotype dependent on the fusion (F) protein of the RSV strain. Epidermal growth factor receptor (EGFR) plays a role in airway mucin expression in other sy...
Several functional tests were performed to compare Hb A, Hb A2, and Hb Lepore Boston, which has a delta-beta crossover in the region of residues 87 to 116. Oxygen equilibrium curves determined by an automatic apparatus in 0.1 M potassium phosphate buffer, pH 7.0, at 20 degrees showed that the p50 was 5.8 mm Hg for Hb Lepore Boston, in contrast to 8.1 and 10.3 mm Hg for Hb A2 and Hb A, respectiv...
We have previously demonstrated that plasmin acts as a potent proinflammatory activator of human peripheral monocytes. Here we identify the annexin A2 heterotetramer, composed of annexin A2 and S100A10, as a receptor for the plasmin-induced signaling in human monocytes. Monocytes express the annexin A2 heterotetramer on the cell surface as shown by flow cytometry, fluorescence microscopy, and c...
چکید ه سابقه و هدف سنجش هموگلوبین به روش نواری به عنوان یک وسیله تشخیصی ساده، قابل اعتماد و کم هزینه برای غربالگری اهداکنندگان خون از نظر کم خونی، قبل از اهدا استفاده می‌شود. هدف از این مطالعه بررسی ارزش تشخیصی روش سنجش نواری هموگلوبین و سولفات مس در مقایسه با روش مرجع(سیان مت هموگلوبین) بود. مواد و روش‌ها در این مطالعه مقطعی، 506 نفر از اهداکنندگان خون به روش سرشماری انتخاب و میزان ه...
We show that the braided tensor product algebra A1⊗A2 of two module algebras A1,A2 of a quasitriangular Hopf algebraH is equal to the ordinary tensor product algebra of A1 with a subalgebra of A1⊗A2 isomorphic to A2, provided there exists a realization of H within A1. In other words, under this assumption we construct a transformation of generators which ‘decouples’ A1,A2 (i.e. makes them commu...
