زمینه و هدف: آلوئولار و سیستیک اکینوکوکوزیس به ترتیب ناشی از مراحل لاروی کرمهای نواری اکینوکوکوس مولتی لوکولاریس و اکینوکوکوس گرانولوزوس می باشد. این مطالعه برای تعیین میزان گسترش بیماری AE و CE انسانی در میان عشایر و دامداران و کشاورزان جلگه مغان صورت گرفته است. شیوع عفونت (CE و AE) به طور معنی داری با سن افزایش می یابد. روش کار: در این مطالعه از روش ELISA و برای بار اول جهت غربالگری از HCF-...
BACKGROUND AND OBJECTIVES A single reactive IgG anti-Dengue virus ELISA test in the absence of IgM antibodies or NS1 antigen may denote current infection or past exposure to the virus. To determine whether IgG index value can be used to identify true current dengue infection we conducted a prospective observational study. MATERIALS AND METHODS Suspected dengue patients (n =1745) were tested i...
Background: Anti-cytosolic 5′-nucleotidase 1A (anti-cN1A) antibodies were proposed as a biomarker for the diagnosis of inclusion body myositis (IBM), but conflicting specificity and sensitivity evidence limits its use. Our study aimed to assess diagnostic accuracy anti-cN1A in cohort patients who underwent line immunoassay suspected idiopathic inflammatory myopathies (IIM). We also assessed agr...
Background and Objective: Since the distribution of HBV genotypes in patients with hepatitis B indicates the predominant genotypes in specific geographical area, this study aimed to investigate the prevalence of S gene mutations in high-risk children with maternal HBV in southeastern Iran. Materials and Methods: This cross-sectional prospective study was performed from March 2019 to March 2020...
results among the 181 anti-hcv ab negative patients, 13 (7.2%) were positive for hcv core ag and 11 (6%) had detectable hcv rna with a range of 40-336543 iu/ml by pcr. the two tests had a high measurement agreement (kappa=0.82, p<0.001). of the 13 patients with positive hcv core ag test results, 3 were negative for hcv rna. considering real time pcr for hcv rna as the gold standard for hcv infe...
BACKGROUND End-stage renal disease patients on chronic hemodialysis are among high risk groups for hepatitis C virus (HCV) infection for whom routine HCV screening is recommended. Anti-HCV antibody (ab) testing may not be reliable to detect all infected cases because of the blunted ab response due to depressed immune state in these patients. Using a more reliable, cost-effective and non-complex...
BACKGROUND Detection of dengue NS1 antigen in acute infection has been proposed for early diagnosis of dengue disease. The aim of this study was to evaluate the clinical and virological factors influencing the performance of the Platelia NS1 Ag kit (BioRad) and to assess the potential use of NS1 antigen and dengue viral loads as markers of dengue disease severity. METHODOLOGY/PRINCIPAL FINDIN...
در این تحقیق واکنش تشکیل کمپلکس بین کاتیون های tl+، ag+ و +2pb با 2و6-دی(فوران-2ایل)-4-(4-متوکسی فنیل)پیریدین (dfmp) به عنوان یک لیگاند سنتزی جدید در سیستم های دو جزئی استونیتریل(an)–آب(o2h)و متانول(meoh)–آب(o2h)در دماهای مختلف بوسیله تکنیک هدایت سنجی مورد مطالعه قرار گرفت.
We have shown previously that an early complement C5-dependent cascade is required to recruit T cells to elicit 24-h contact sensitivity (CS) responses. In this paper, we have characterized molecular events of this early required cascade by biochemically analyzing extracts of mouse ears undergoing elicitation of CS. Chemotactic activity was found after local Ag challenge, in CS ear extracts ear...
