rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
even though, to date, a lot of studies have been conducted on the subject of politeness theory, there are very few studies regarding the applicability of this theory to translation between english and persian which shows the reason behind conducting the present study. this study was carried out with the aim of highlighting whether there is any difference between english and persian methods of u...
Removal of seminal plasma facilitates stallion sperm survival during storage, but washing may damage chromatin. Therefore, quality was compared in samples following single-layer centrifugation (SLC) or and controls (extension only) two extenders, INRA82 INRA96. Ejaculates from six stallions were split among treatments: SLC, washing, controls, Sperm motility acrosome status evaluated at 0, 24, 4...
evidence suggests that human sperm chromatin anomalies adversely affect reproductive outcomes and infertile men possess substantially amount of sperm with chromatin anomalies than fertile men. routine semen analysis evaluates parameters such as sperm motility and morphology, but does not examine the nuclear dna integrity of spermatozoa. it has been suggested that altered nuclear chromatin struc...
Background: Cisplatin (CIS), an anticancer alkylating agent, induces DNA adducts and effectively cross links the DNA strands and so affects spermatozoa as a male reproductive tract toxicant. Materials and Methods: The present study investigated the cellular/biochemical mechanisms underlying possible protective effect of selenium nano-particles (Nano-Se) as an established strong antioxidant with...
Massive parallel DNA sequencing combined with chromatin immunoprecipitation and a large variety of DNA/RNA-enrichment methodologies is at the origin of data resources of major importance. Indeed these resources, available for multiple genomes, represent the most comprehensive catalogue of (i) cell, development and signal transduction-specified patterns of binding sites for transcription factors...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
abstract this study tried to investigate whether there was any significant relationship between technical translation quality of the senior english translation students and their levels of verbal-linguistic, visual-spatial and interpersonal intelligences. in order to investigate the research questions, the researcher selected a hundred senior english translation students from three universitie...
the aim of this study was to investigate the effect of adding different levels of zinc sulfate in semen extender on bovine sperm quality during cryopreservation. semen was collected from 4 holstein bull twice a week and the proper samples were pooled. semen were allocated to four extender treatments consisted of 0, 50, 100, 150 µm of zinc sulfate in 5 replicates and then, were frozen. post-thaw...
