CONTEXT Dopamine receptor-mediated pathways play critical roles in the mechanism of addiction. However, associations of the D(2) dopamine receptor gene (DRD2) with substance abuse are controversial. OBJECTIVE To determine whether susceptibility sites resided at DRD2. DESIGN Haplotype-based case-control analysis of 2 distinct populations using 10 single nucleotide polymorphisms (SNPs) with h...
This study was conducted in the laboratories of Department Animal Production College Agriculture - University Basrah for period from 1/11/2021 to 1/5/2021. The data this were collected Dhi Qar Governorate included samples blood and meat. These taken 30 imported local (Jenoubi) calves aged (1 2) years. Ten ml as well 250 g meat thigh, shoulder back area all animals. DNA extracted primer DNMT3b...
The Amur grape (Vitis amurensis Rupr.) thrives naturally in cool climates of Northeast Asia. Resistance against the introduced pathogen Plasmopara viticola is common among wild ecotypes that were propagated from Manchuria into Chinese vineyards or collected by Soviet botanists in Siberia, and used for the introgression of resistance into wine grapes (Vitis vinifera L.). A QTL analysis revealed ...
medullary thyroid carcinoma (mtc) occurs in both sporadic (75%) and hereditary (25%) forms. the missense mutations of the rearranged during transfection (ret) proto-oncogene in mtc development have been well demonstrated. the aim of this study was to investigate frequency of g691s/s904s haplotype in mtc patients and their relatives.in this research 293 participants were studied, including 181 p...
Human hemoglobins, the oxygen carriers in the blood, are composed by two a-like and two b-like globin monomers. The -globin gene cluster located at 11p15.5 comprises one pseudogene and five genes whose expression undergoes two critical switches: the embryonic-to-fetal and fetal-to-adult transition. HBD encodes the d-globin chain of the minor adult hemoglobin (HbA2), which is assumed to be physi...
Sickle cell hemoglobin is a β chain structural variant where valine is substituted for glutamic acid in the sixth amino acid position. A point mutation (A--->T) in codon 6 of the β globin gene which is located on the short arm of chromosome 11 is responsible for this abnormality. Despite the fact that all sickle cell disease patients have an identical single base change in their DNA, the severi...
We characterized the pattern and magnitude of phylogeographical variation among breeding populations of a long-distance migratory bird, the Wilson's warbler (Wilsonia pusilla), and used this information to assess the utility of mtDNA markers for assaying demographic connectivity between breeding and overwintering regions. We found a complex pattern of population differentiation in mitochondrial...
Knowledge about community structure and genetic diversity can help assess the potential for change in loss restoration of biodiversity, thereby facilitating effective management ecosystem protection. Macroinvertebrate communities are an important biotic component deep sea cold seep ecosystems. As Haima is increasingly being assessed its gas hydrate mineral wealth, knowledge characteristics macr...
Morphological similarities of the populations and species of the genus Ponticola in the southern Caspian Sea make their identification difficult based on the provided keys. Molecular markers are used as a supplementary tools to better understanding of the fishes’ taxonomic statues. This study was conducted to understand taxonomic statues of gobiids from 6 rivers (Siah, Zaringol, Babol, Tajan, S...
