introduction: previous studies have indicated that stress levels of glucocorticoid hormones induce impairment of long term memory retrieval, but the underlying mechanisms (genomic or non-genomic) are not clear. to clarify this issue, we investigated the involvement of brain corticosteroid receptors and protein synthesis in the glucocorticoid-induced impairment of memory retrieval. methods: 140 ...
abstract: a pure nucleotide pool is an essential precursor of correct dna replication and prevention of mutagenesis and abnormality in a living cell. inosine triphosphatase (itpase) is a critical enzyme to remove any deaminated rough purine nucleotides such as inosine from nucleotide pool. it has been shown that the rate of substitution mutation in genomic dna increase by abnormal function and ...
The genomic and cDNA clones encoding cellobiohydrolase II (CBHII) have been isolated and sequenced from a native Iranian isolate of Trichoderma parceramosum, a high cellulolytic enzymes producer isolate. This represents the first report of cbhII gene from this organism. Comparison of genomic and cDNA sequences indicates this gene contains three short introns and also an open reading frame codin...
Embryo transfer (ET) in Holstein dairy cattle became an important commercial enterprise after the introduction of non-surgical recovery technique. Embryo transfer could increase the reproductive rate of genetically superior cows. The objectives of the present study were to evaluate the use of ET in Iranian Holstein dairy cattle to increase selection intensity on the dam side, economically; esti...
Background: Anti-dsDNA antibodies frequently found in the sera Systemic Lupus Erythematosus patients, particularly in active disease stage. Nowadays exploit different eukaryotic and prokaryotic dsDNA as antigen source and different reagents as binder. The aim of this study to compared two dsDNA different sources and tow different kinds of reagents for binder in ELISA test. Methods: In this stu...
The purpose of this study was to compare the accuracy of genomic evaluation for Bayes A, Bayes B, Bayes C and Bayes L multi-step methods and SSBR-C and SSBR-A single-step methods in the different values of π for predicting genomic breeding values of the genotyped and non-genotyped animals. A genome with 40000 SNPs on the 20 chromosom was simulated with the same distance (100cM). The π valu...
هدف از این مطالعه بررسی انتقال یک ژن عمده با روشهای سنتی (Classic)، ژنومیک (Genomic)، سنتی با انتخاب به کمک ژن (GasClassic) و ژنومیک با انتخاب به کمک ژن (GasGenomic) برای بهبود صفت چندقلوزایی با استفاده از شبیهسازی رایانهای در یک جمعیت گوسفند بود. بدین منظور صفتی با وراثتپذیری 1/0 شامل دو کروموزم که هر یک به طول صد سانتی مورگان بود، شبیه سازی شد. بر روی هر کروموزم 10000 SNPو 100QTL به صورت ...
