The use of polymorphic markers in breeding programmes could make selection more accurate and efficient. A total of 324 individuals from six Iranian cattle populations (Sarabi, Golpayegani, Sistani, Taleshi, Mazandarani, Dashtiyari), F1 Golpayegani × Brown Swiss and Iranian buffalo populations were genotypedfor the Pit-1 HinfI and leptin Sau3AI polymorphisms by the polymerase chain reactio...

wiskott-aldrich syndrome (was) is a life-threatening x-linked recessive immunodeficiency disease described as a clinical triad of thrombocytopenia,  eczema, and recurrent infections, caused by mutations of the was protein (wasp) gene. the milder form of this disease is x-linked thrombocytopenia  (xlt) that  presents only as platelet abnormalities. mutation analysis for 15 boys with wiskott-aldr...

idiopathic hypogonadotropic hypogonadism (ihh) is a condition caused by low doses of hypothalamic gonadotropin-releasing hormone (gnrh) leading to absence or incomplete sexual maturation. one of the disorders leading to ihh is kallmann syndrome which is characterized by gnrh deficiency with anosmia or hyposmia. this disorder generally occurs as a hereditary syndrome with x-linked recessive inhe...

Introduction: X chromosome inactivation (XCI) is a process during which one of the two X chromosomes in female human is silenced leading to equal gene expression with males who have only one X chromosome. Here we have investigated XCI ratio in females with opioid addiction to see whether XCI skewness in women could be a risk factor for opioid addiction. Methods: 30 adult females meeting DS...

background: cytogenetic analysis, y-chromosome microdeletion screening, fish techniques and other genetic methods have helped in finding the causes of infertility in azoospermic or severe oligoazoospermic cases in the last decade. objective: in the present study, we characterized an abnormal y-chromosome, detected as a mosaic in an azoospermic male ascertained for infertility. materials and met...

background:   objective: in this study we performed linkage analysis on a large x linked rsa pedigree to find a novel susceptibility locus for rsa.   materials and methods: a linkage scan using 11 microsatellites was performed in 27 members of a large pedigree of hereditary x-linked rsa. two point parametric linkage was performed using superlink v 1.6 program. results: evidence of linkage was o...

background and objectives: isolation of xanthomonas campestris from soil has a wide range of applications from monitoring of phytopathogenic populations in soil to screening of improved xanthan-producing strains. identification of xanthomonas campestris and its pathovars requires pathogenicity tests in addition to phenotypic and molecular characterization. materials and methods: thirty phenotyp...
