background: equine piroplasmosis is caused by two haemoprotozoan parasites: babesia caballi and theileria equi . negative economic impact on international trade has been associated to endemic sites. this is the reason why carrier detection requires reliable diagnostic methods. various diagnostic modalities can be used alone or in combination including pcr. however, genetic variation of commonly...

infertility can be caused by an unexplained reduction in semen quality in males who present asnormal on physical examination and endocrine testing. there is some evidence that aberrantmetabolism of micronutrients such as choline may play a causative role in male factorinfertility. choline is a crucial factor in the regulation of sperm membrane structure andmotility, and this nutrient plays an i...

the barn owl, tyto alba (scopoli, 1769), occurs worldwide and shows a considerable amount of morphological and geographical variation, leading to the recognition of many subspecies around the world. yet comprehensive study on this species needs to be done. data from mitochondrial gene (cytb) with 620bp length is analyzed for 30 individuals around the world. maximum likelihood (ml), maximum pars...

background: for screening sequence variations in genes, rapid turnover time is of fundamental importance. while, many of the current methods are unfortunately time consuming and technically difficult to implement. denaturing high-performance liquid chromatography (dhplc) method had been shown to be a high-throughput, time saving, and economical tool for mutation screening. objective: in the pre...

Melanocortin-3 receptor (MC3R) plays an important role in the central control of energy homeostasis, and several functional polymorphisms of this gene have been detected. We have studied MC3R as a candidate gene responsible for variation in economically important traits in chicken. To determine the association between MC3R polymorphism and phenotypic variation, a total of 190 individuals from b...

In this report, β-tubulin gene polymorphism was investigated in Haemonchus contortus  populations isolated from sheep flocks in different regions of Khouzestan province, southwestern Iran. The samples were chosen on the basis of regional variation in benzimidazole treatment background of sheep flocks. Our objective was to study the relationship between treatment background andβ -tubulin gene po...

Background: Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Several studies have shown that ALL occurs as a result of genetic abnormalities. 1, 25-Dihydroxyvitamin D3 as a secosteroid hormone plays an important role in different metabolic pathways. The normal function of vitamin D occurs via binding to a ligand-activated transcription factor i.e. vitamin D receptor (VDR)...

conclusions the present findings showed that the ta7/7 promoter of ugt1a1 gene accounted for a considerable number of gilbert’s syndrome cases (11.3%). the studied variations had a significant effect on creatine phosphokinase and serum total bilirubin levels. results about 78.9% of the studied subjects had normal homozygous genotypes, and 21.1% were heterozygous for the gly71arg variation. in t...

Esox lucius is an economically important freshwater species. Mitochondrial cytb, 12SrRNA, and 16SrRNA gene sequences were used in order to clarify the genetic variation and population structure in three E. Lucius populations, i.e., one Wild population (W) and two hatchery populations (Hatchery Population I-HPI and Hatchery Population II-HPII). A total of 55 individuals, with 19 from wild and 1...
