Varicocele is one of the most common causes of low semen quality, which is reflected in high percentages of sperm cells with fragmented DNA. While varicocelectomy is usually performed to ameliorate a patient's fertility, its impact on sperm DNA integrity in the case of subclinical varicocele is poorly documented. In this study, multiple DNA fragmentation analyses (TUNEL, SCD, and SCSA) were per...

The positioning and format of performance assessment in examination physical education varies between courses across Australia internationally. This paper centres on developments the Physical Education Studies (PES) course Western (WA). In 2021 School Curriculum Standards Authority (SCSA) undertook an validation trial school-based students participating modified competitive game play 10 PES spo...

It is well known that transit through the epididymis involves an increase in the compaction of sperm chromatin, which acquires fully condensed status at the caput epididymidis. The purpose of this study was to compare the terminal deoxyribonucleotidyl transferase-mediated dUTP nick end-labelling (TUNEL) assay, the comet assay, the sperm chromatin structure assay (SCSA) and the sperm chromatin d...

Host stress is well known to result in flare-ups of many bacterial, viral and parasitic infections. The mechanism by which host stress is exploited to increase pathogen loads, is poorly understood. Here we show that Salmonella enterica subspecies enterica serovar Typhimurium employs a dedicated mechanism, driven by the scsA gene, to respond to the host stress hormone cortisol. Through this mech...

The aim of this study was to investigate whether the sperm chromatin structure assay (SCSA) results after swim-up are related to fertilization rates, embryo quality and pregnancy rates following in vitro fertilization (IVF). A total of 223 couples undergoing IVF in our hospital from October 2008 to September 2009 were included in this study. Data on the IVF process and sperm chromatin structure...

In the discipline of civil engineering, foundation plays a crucial role in supporting and containing loads complete structures. Therefore, needs to be strong enough increase any structure's useful life. The soil has direct impact on foundation. Vertisols is with unstable weak that stabilized make suitable for construction purposes. study determine effectiveness pulverized used paper sugarcane s...

Over the past 25 years, various methods have been developed to measure sperm DNA strand breaks in situ. Currently, there are four major tests of sperm DNA fragmentation, including the Comet, Tunel, sperm chromatin structure assay (SCSA) and the acridine orange test (AOT). The Comet assay is a light microscope technique where the sperm cells are mixed with melted agarose and then placed on a gla...

The objective of the present study was to explore the potential relationships of ovine sperm chromatin integrity, quantified using the sperm chromatin structure assay (SCSA), to the heat load of the scrotum and the discomfort felt by the animals because of fluctuations of microclimatic factors at different time periods before ejaculation. Ejaculates were collected once per week from five Chios ...

Object detection is one of the most widespread applications for numerous Unmanned Aerial Vehicle (UAV) tasks. Due to shooting angle and flying height UAV, compared with general scenarios, small objects account a large proportion aerial images, common object detectors are not extremely effective in images. Moreover, since computing resources UAV platforms generally limited, deployment number par...
