OBJECTIVE Intestinal gamma/delta- intraepithelial lymphocytes (IEL) have increased in children with juvenile idiopathic arthritis (JIA). To further characterise intestinal immune activation in these children, we have quantitated cytotoxic lymphocytes in intestinal mucosa. METHODS We studied 23 children with JIA suffering from gastrointestinal symptoms with gastroduodenoscopy and colonoscopy. ...

The aim of this paper is to investigate the multiple attribute decision making problems with intuitionistic fuzzy information, in which the information about attribute weights is incompletely known, and the attribute values take the form of intuitionistic fuzzy numbers. In order to get the weight vector of the attribute, we establish an optimization model based on the basic ideal of traditional...

We propose a generalized regression neural network (GRNN) approach based on grey relational analysis (GRA) and principal component analysis (PCA) (GP-GRNN) to improve the accuracy of density functional theory (DFT) calculation for homolysis bond dissociation energies (BDE) of Y-NO bond. As a demonstration, this combined quantum chemistry calculation with the GP-GRNN approach has been applied to...

Glucocorticoid-remediable aldosteronism (GRA) is an autosomal-dominant inheritable form of hyperaldosteronism with early onset hypertension. GRA is caused by unequal crossing-over of the steroid 11 beta-hydroxylase (CYP11B1) and aldosterone synthase (CYP11B2) genes. As a result of chimeric gene duplication, aldosterone is ectopically synthesized in the adrenal zona fasciculata under the control...

Activated CTLs and NK cells induce apoptosis via multiple mechanisms, including that termed granule exocytosis. The latter pathway consists of vectorial secretion of perforin and a family of granule-associated serine proteases (granzymes) to the target cell. To establish whether granzymes are released extracellularly during cytolytic reactions in vivo, ELISAs that measure the native enzymes wer...

Purpose – The relationship between energy consumption (EC) and economic growth is a well-known and more studied subject in literature. In this study, Turkey’s EC and gross domestic product (GDP) relation is analyzed. The aim of this study is to find out the relative importance of energy components on GDP for Turkey. Hence, the authors can make some strategic implications up to the importance of...

INTRODUCTION Sulforaphane (SFN) is an isothiocyanate derived from glucoraphanin (GRA), which is found in great amounts especially in broccoli. Its consumption has been reported to be associated with a lower risk of myocardial infarction and cancer development. Additionally, its effects have been studied in neurodegenerative diseases, diabetes, and atherosclerosis, most of the times using animal...

چکیده- صفحات مستغرق، سازه­هایی هستند که در بستر رودخانه­ها و کانال­ها با زاویه­ای در برابر جریان نصب می شوند. این سازه­ها معمولاً به صورت گروهی استفاده می­شوند و کارکرد اصلی آن ها ایجاد جریان گردابی و تغییر الگوی جریان و بستر است. کارکرد صفحات مستغرق تحت تأثیر شاخص های هندسی آن ها است. در این پژوهش، شاخص های هندسی یک صفحه مستغرق در بستر رسوبی کانال مستقیم با مدل سازی عددی بهینه سازی شده است. منظ...

Herein, we have investigated the adsorption behavior of gas molecules, including C2H2, H2S, SO2, SO3, and O2, on FeN3-doped graphene (FeN3-gra). The change geometric stability, electric structure, magnetic properties is discussed comprehensively. results demonstrated that stability substrate enhanced by hybridization between Fe N atoms in FeN3-gra. Besides, dopant can enhance ability gases grap...
