Regarding low fertilization rate of Barbus sharpeyi, one of the main Barbus species in south of Iran, saline activator solutions (SAS 1 and 2) were used for increasing of sperm activation and its sperm quality indices were assessed by using Image J software as a fish sperm adapted tools. SAS 1 (45mM NaCl, 5mM KCl, 30mM Tris, 188±2.3 mosmol/kg) and SAS 2 (50mM NaCl, 30mM KCl, 30mM Tris, 189±1.7 ...

Background Low levels of reactive oxygen species (ROS) and calcium are necessary for sperm function. NADPH oxidase 5 (NOX5) is a membrane enzyme which produces ROS. This enzyme is dependent on calcium for its activity. We investigated the importance of NOX5 and an important calcium channel (CatSper) on sperm function. Methods This laboratory in-vitro study was done in Shiraz, Iran, 2016. Norm...

Background Cryopreservation procedure for poultry semen is not reliable due to structural and biochemical damages which can lead to reduction in sperm quality and fertility. Development of cryopreservation medium has crucial effects for successful recovery of sperm after freezing. The objective of this study was assessment of cryopreservation of rooster semen using hand-made cryopreservation me...

A photographic description of meiosis and spermatogenesis in single sperm cysts of Drosophila melanogaster cultured in vitro is presented. In addition to the utility of this description for the study of spermatogenesis in whole live testes, the culture procedure provides a means for studying the dynamic development of individual sperm cysts from flies carrying male-sterile mutations, as illustr...

The maintenance or reengineering of an object-oriented system includes its reverse engineering. In other words its internal structure and behavior needs to be understood. Many researchers have proposed different techniques to support the reverse engineering effort. The two predominant approaches to reverse engineering are: • static analysis of source code • dynamic analysis of behavior of a sys...

The aspiration of this study is to perform the comparative analysis of static and dynamic metric for structured programming environment. Software metrics is one of the vital tools that can be worn to find significant estimates for software products and directs us in intriguing managerial and technical decisions. Software metrics have become an integral part of software development and are used ...
