Genomic growth hormone gene polymorphisms in native Chinese chickens.
Chicken growth hormone (cGH), a polypeptide hormone synthesized in and secreted by the pituitary gland, is involved in a wide variety of physiological functions such as growth, body composition, egg production, aging, and reproduction. Chicken growth hormone polymorphisms have been reported to be associated with certain phenotypes. Our objective is to investigate the GH gene polymorphism in sel...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولGrowth Hormone Gene Polymorphism in Two Iranian Native Fowls (Short Communication)
Biochemical polymorphism study is a method of determination of genetic variation. This variability could be a basis for selection and subsequent genetic improvement in farm animals. The polymorphism in the intron 1 of chicken growth hormone (cGH) gene was investigated in the Iranian native fowls by using polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method. The...
متن کاملO-36: Evaluation of Genetic Variations in Intron 4 and Exon 5 of RABL2B Gene in Infertile Men with Oligoasthenoteratospermia and Immotile Short Tail Sperm Defects
Background One of the main causes of male infertility is defect in structure and function of sperm cells. Infertile men with oligoasthenoteratospermia (OAT) defect, have sperms with abnormalities in count, motility and morphology. Patients with immotile short tail sperm (ISTS) disorder have immotile short-tailed sperm with disorganized axonem, and a significant decrease in sperm counts. Numerou...
متن کاملOntogeny of growth hormone receptor gene expression in tissue of growth-selected strains of broiler chickens.
The purpose of this study was to determine the relationship between genetic selection for growth traits and tissue expression of the chicken growth hormone receptor (cGHR) gene. Two different populations of broiler chickens were studied. One population consisted of strain (S) 80, selected for 14 generations for high 9-week body weight (BW), and its progenitor, S90 (a 1950's strain). The second ...
