، hla-a شامل hla تعداد 500 نفر از مردم اصفهان که از سلامتی کامل برخوردار بودند، از نظر آنتی ژنهای گروه یک مورد آزمایش قرار گرفتند. روش آزمایش به این شکل بود که در هر نمونه لنفوسیت ها از 5 میلی لیتر hla-c و hla-b از نظر nih خون وریدی جدا می شدند و با استفاده از روش استاندارد دو مرحله ای میکرولنفوسیتوتوکسیسیتی تحت بررسی قرار می گرفتند. نتایج بدست آمده حاکی از آن است که شیوع hla-c و hla-b ، ...
Objectives: Accurately identifying the Antigens (Ags) on recipient red blood cells (RBCs) is critical in prevention of RBC alloimmunization in chronically transfused patients. The goal of this study was to compare RBC molecular genotyping to serological phenotyping in those patients. Methods: Serological phenotyping and molecular genotyping methods were used to study blood samples from 18 healt...
Introduction: Recognition of human leukocyte antigens (HLA) is of importance for hematopoietic stem cell transplantation. Any HLA-mismatches between the donor and recipient can cause graft rejection or other complications. In HLA-typing experiments, usage of HLA-known reference cells accompany with HLA-unknown samples is obligatory. Some international centers represent these cells with high e...
Objective: This study aimed to investigate the association between HLA alleles and visceral leishmaniasis (VL) in a sample of Iraqi patients. Methods: A total of 30 patients were studied, in addition to 20 age, gender and ethnicity matched controls. All subjects were genotyped by polymerase chain reaction-sequence specific primers (PCR-SSP) method. Results: For HLA-class I region (A and B loci)...
چکید ه سابقه و هدف با توجه به تاسیس مرکز پذیرش اهداکنندگان سلول‌های بنیادی خونساز در سازمان انتقال خون ایران (مرکز سپاس) در سال 1387, بر آن شدیم به بررسی آنتی‌ژن‌های سازگاری بافتی داوطلبان اهدای این سلول‌ها از قومیت‌های حاضر در شهر تهران طی سال 91-90 بپردازیم. مواد و روش‌ها در یک مطالعه توصیفی، 1513 نفر از افراد داوطلب عضو مرکز سپاس در محدوده سنی 18 تا 50 سال و با سابقه یک بار اهدای خ...
Background: Non-Hodgkin lymphoma (NHL) includes a wide range of diseases with different clinical and biological features. NHL is usually presented as localized or generalized lymphadenopathy. It has been suggested that the HLA class I and II are associated with susceptibility to NHL. Different ethnic groups have been found to have different HLA class I and II alleles which affect NHL. Objective...
Root phenotyping provides trait information for plant breeding. A shortcoming of high-throughput root phenotyping is the limitation to seedling plants and failure to make inferences on mature root systems. We suggest root system architecture (RSA) models to predict mature root traits and overcome the inference problem. Sixteen pea genotypes were phenotyped in (i) seedling (Petri dishes) and (ii...
The association of HLA and disease varies in different populations. We have . studied the association of HLA class I in Iranian psoriatic patients, in order to compare this association with other reports. Fifty-one Iranian patients with psoriasis were HLA typed. The frequency of HLA antigens in patients and patient subgroups, based on clinical patterns, age of onset, family history and prov...
Background: Human leukocyte antigen (HLA) class II has shown potential in determining prognosis, understanding medication reactions, and predicting onset of Graves’ disease. The aim this study is to further investigate the association between disease HLA II, specifically HLA-DQ HLA-DR, via meta-analysis find HLAs that can be examined for prognostic reasons.
Gene variants derived from Neanderthals or Denisovans can be associated with polygenic traits, validating the utility of notion about archaic gene flow. Endoplasmic reticulum aminopeptidase 1 (ERAP1) haplotypes control disease risk primarily mediated by HLA-C*06:02, HLA-B*27 and HLA-B*51 for psoriasis, ankylosing spondylitis (AS) Behçet's (BD). In this genetic interaction corresponds to differe...
