Determination Of Plant-Specific Retrotransposons In Chicken, Levent Mercan, Ci̇hat Erdem Bülbül, Fati̇h Bi̇lgi̇, Sevgi̇ Marakli

Turkish Journal of Veterinary & Animal Sciences

Mobile genetic elements are also known as transposons, comprising a significant proportion of plant and animal genomes. Retrotransposons, a class of transposons, move copy and paste mechanism and, therefore, cause genome obesity. Moreover, the transferability of retrotransposons within and between different kingdoms has provided valuable information for evolutionary relationships in addition to detailed knowledge about genomes. We identified barley-specific retrotransposons (Nikita and Sukkula) and determined polymorphism ratios of these retrotransposons in a chicken genome for the first time to gain new insights for retrotransposons found in different genomes. Transposon sequences belonging to chicken and barley genomes were also investigated to …

A Game Theoretic Approach To Design Mating Programs For Livestock, Ebru Ergüneş Berki̇n, Hasan Önder, Özgür Hakan Aydoğmuş

Turkish Journal of Veterinary & Animal Sciences

In this study, we proposed a new game theoretic method to design a mating program. The index and game theoretic methods were applied with calculated breeding values using pedigree on two different data sets whose economic traits consist of negative (milk yield and fat percentage) and positive (birth and weaning weight) genetic correlated data. For the negative genetic correlated data set, even if total expected benefits were equal for two methods, mating programs were changed, and the coefficient of variation obtained using the game theoretic method was smaller than that of the index method. This result showed that the expected …

Effects Of Centrifugation And Washing Of Freeze-Thawed Blood On Isolated Dna Characteristics, Mevlüt Arslan Jan 2022

Effects Of Centrifugation And Washing Of Freeze-Thawed Blood On Isolated Dna Characteristics, Mevlüt Arslan

Turkish Journal of Veterinary & Animal Sciences

DNA isolations from the whole blood are commonly performed to obtain DNA for molecular research and diagnostics. Generally, blood samples are taken into anticoagulant tubes and stored in deep freezers until DNA isolation. In fresh blood, pretreatments or leukocytes preparations can be performed and suggested for advanced DNA isolation. However, similar applications in freeze-thawed blood (FTB) have not been shown yet. In the study, centrifugation and washing of FTB were applied as pretreatment before DNA isolations, and their effects on isolated DNA characteristics including DNA integrity, quality, quantity, mitochondrial (mt), and nuclear (n) DNA levels were investigated.

Background/aim: Infertility is a global problem that brings about serious sexual and social consequences that strain the health sector and society. The expansion of CAG and GGC repeats in androgen receptor (AR) gene (Ensembl number ENSG00000169083) may lead to reduced fertility. Our objective was to determine the association of CAG and GGC repeats with altered sperm parameters in male infertile subjects. Materials and methods: This was a cross-sectional study conducted at Aga Khan University, Karachi, Pakistan. A total of 376 males were recruited, out of which group A (N = 208) and group B (N = 168) were comprised of …
