recurrent aphthous stomatitis (ras) is known as the most common chronic disease of the oral cavity, which affects a range of 5-25% of the population. ras appears to be associated with some human leukocyte antigen (hla) class ii alleles and haplotypes. this study attempts to survey the distribution of hla-drb and -dqb alleles among iranian ras patients and healthy controls. in order to evaluate ...

background: pulmonary tuberculosis (pt) is one of the endemic diseases in iraq, and among the suggested predisposing factors are alleles of the human leukocyte antigen (hla) system. we sought to investigate the association between hla-class i (a and b) and -class ii (dr and dq) alleles in a sample of pt iraqi patients. methods: lymphocytes of 105 pt patients and 40 controls were phenotyped for ...

background: a common human leukocyte antigen (hla) class ii allele, dqβ1*03:01, seems to be associated with bullous pemphigoid (bp) in caucasians whereas previous studies in other ethnic groups showed other hla class ii alleles as genetic predisposing factors for bp. objective: to investigate the association of hla class ii alleles and haplotypes with bp in iranian population. methods: fifty pa...

53 persons suspected to alpha1-antitrypsin deficiency detection (aatd) were investigated for zz, mz, zs, ss, and ms alleles analysis by serum protein electrophoresis (spe), measurement of trypsin inhibiting capacity (tic), isoelectric focusing (ief), polymerase chain reaction (pcr), and ief/pcr-rflp techniques. the result clearly shows by using spe and tic techniques only 35.85 % and 50.08% of ...

in an attempt to characterize theileria parva parasites circulating in south sudan cattle , polymerase chain reaction (pcr)-based assays were carried out using four single copy encoding antigen genes p104, pim, p150 and p67 in addition to one microsatellite ms321. a total of 20 bovine dna samples from two locations in south sudan were included in this study, in addition to two references strain...

Human leukocyte antigen (HLA) genes have been associated with susceptibility and protection against a number of cancers. Here we used an immunogenetic epidemiological approach to evaluate the overall influence 127 HLA Class I II alleles on 30 types cancer. We found preponderance protective (negatively correlated cancer prevalences), especially for I. Of cancers investigated, 13 were mostly effe...
