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...

The Holstein bulls (n=50) were genotyped for bovine lymphocyte antigen (BoLA-DRB3.2) alleles by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). Genomic DNA was extracted from bull semen using phenol-chloroform method. A two-step PCR was conducted in order to amplify a 284 base-pair fragment of the target gene. Amplicons were digested by RsaI, HaeIII and BstyI ...

Background: The length of GT-repeats polymorphic region in the promoter of human Heme oxygenase-1 gene (HO-1) alters the level of its transcriptional activity in response to oxidative stresses. Decreased level of HO-1 protein in the seminal plasma has been reported to be associated with oligospermia and azoospermia in male infertility. This is the first study to investigate the association betw...

background: genetic polymorphisms of cytochrome p450 in humans are the main cause of differences in the metabolism. the allele and genotype frequencies of cyp2c19 and cyp2c9 have been studied in some iranian populations. the aim of present study was to examine the frequencies of cyp2c18m1, and cyp2c18m2, alleles in the mazandarani ethnic group among iranian population. materials and methods: in...

The present research aims to study the association and allelic diversity of linked microsatellite markers to grain quality QTLs of 84 exotic rice genotypes. To this end, 9 microsatellite markers (RM540, RM539, RM587, RM527, RM216, RM467, RM3188, RM246, RM5461) were used in which a total of 61 alleles were identified with a mean of 6 alleles per locus. The polymorphism information content (PIC) ...

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: The myotonic dystrophies (DM1, DM2) are the most common adult muscle diseases and characterized by multisystem involvement. DM1 has been described in diverse populations, whereas DM2 seems to occur primarily European Caucasians. Both caused expression of expanded microsatellite repeats. In DM1, there is a reservoir premutation alleles; however, have no reported alleles for DM...

Background: Cytochrome P450 2C19 (CYP2C19) is a polymorphically expressed enzyme that shows marked interindividual and interethnic variation. CYP2C19*2 and CYP2C19*3 are the most frequently identified defective alleles in Orientals and Caucasian poor metabolizers (PM). The aim of this study was to investigate the frequencies of CYP2C19*1, CYP2C19*2 and CYP2C19*3 alleles and CYP2C19 genotypes in...
