UNLABELLED The HLA-DRB1 alleles encoding an amino acid sequence (QKRAA/QRRAA/RRRAA) at position 70 74 of the third hypervariable region of the β1 chain of the HLA-DRB1 gene, called shared epitope (SE), are associated with increased susceptibility to and severity of rheumatoid arthritis (RA) in different populations. OBJECTIVE To determine the frequency of HLA-DRB1 alleles in Brazilian patient...
BACKGROUND HLA-DRB1 alleles are major determinants of genetic predisposition to rheumatic diseases. We assessed whether DRB1 alleles are associated with susceptibility to particular clinical features of adult onset Still's disease (AOSD) in a Japanese population by determining the DRB1 allele distributions. METHODS DRB1 genotyping of 96 patients with AOSD and 1,026 healthy controls was perfor...
OBJECTIVE Human leukocyte antigen (HLA) DRB1*04:36 is a low-frequency HLA-DRB1 allele. The aim here is to report the ethnicity of DRB1*04:36 and its associated HLA haplotypes among Taiwanese individuals. MATERIALS AND METHODS A sequence-based typing method was employed to confirm this low incidence allele. Polymerase chain reaction was performed to amplify exons 2 and 3 of the HLA-A and HLA-B...

مقدمه: بیماری مالتیپل اسکلروزیس یک بیماری خود ایمن، دمیلینه کننده و تخریب کننده سیستم اعصاب مرکزی است. آسیبشناسی این بیماری تا کنون مشخص نشده است، اگرچه شواهدی حاکی از تاثیر عوامل محیطی بر افراد دارای استعداد ژنتیکی وجود دارد. در بسیاری از مطالعات مبتنی بر جمعیت نقش هاپلوتایپ های hla drb1*15 (hla drb1*1501, dqa1*0102, dqb1*0602) در خطر ابتلا به ms تکرار و تایید شده است. با این حال، مطالعات تعدا...
Two hundred Japanese panels were serologically typed for human leukocyte antigen (HLA) - DR to assign 65 HLA-DR8 haplotypes, which were then subdivided into two genotypes, i.e., DRB1*0802 and DRB1*0803, by a polymerase chain reaction (PCR)--based, simple, and practical method. The panels possessing DR8 specificity were firstly subjected to PCR with a couple of primers specifically to amplify th...
OBJECTIVE The protective effect of HLA-DRB1 alleles on the development of rheumatoid arthritis (RA) is poorly understood. The aim of this study was to perform a meta-analysis of 4 European populations to investigate which HLA-DRB1 alleles are associated with protection in anti-citrullinated protein antibody (ACPA)-positive RA and ACPA-negative RA. METHODS Data for >2,800 patients and >3,000 c...
We investigate diffusion-limited aggregation (DLA) in a wedge geometry. Arneodo and collaborators have suggested that the ensemble average of DLA cluster density should be close to the noise-free selected Saffman-Taylor finger. We show that a different, but related, ensemble average, that of the conformal maps associated with random clusters, yields a nontrivial shape which is also not far from...
I review current results from searching for galaxies giving rise to damped Lyα absorbers (DLAs) at z < 1. Using 14 confirmed DLA galaxies, I further show that intermediate-redshift galaxies possess large H I envelope out to 24−30 h kpc radius. The photometric and spectral properties of these galaxies confirm that DLA galaxies are drawn from the typical field population, and not from a separate ...
Several studies have focused on polymorphisms of major histocompatibility complex (MHC) in sheep, Ovar-MHC. This molecule plays a pivotal role in antigen presentation for eliciting immune responses against invading pathogens. The best-characterized genetic control of disease resistance and immune response in animals is associated with MHC. Numerous molecular genetic investigations have been und...
