Background Asthenozoospermia accounts for almost 50% of the cases of male infertility. Our study investigating phosphoproteins differentially expressed in asthenozoosperm has identified the phosphoproteins relevant to sperm motility and the signature molecules likely to be altered in asthenozoospermia. The 66 phosphoproteins differentially expressed included four alpha tubulin isoforms which we...

Dynamic geometry software (DGS), especially GeoGebra, have been used in mathematics lessons around the world since it enables a dynamic learning environment. To date, there exist so many published researches about DGS, which leads to need for meaningful organisation. This study aims give broad picture related DGS. For this reason, 210 articles accessed from Web of Science database were analysed...

dynamic assessment (da) which is rooted in vygotsky’s (1978) sociocultural theory involves the integration of instruction and assessment in a dialectical way to achieve two main purposes: enhancing learners' development and understanding about their learning potential. however, the feasibility and appropriateness of mediation are two main concerns of da. the former is concerned with the applica...

The software was designed to process and conduct comparative analysis of Big medical statistical data. This is easy use. It allows the indexes in dynamics, gives a fair assessment time-series tendencies, helps compare studied presents graphic display information. can be used by health-care institutions, high education health-related scientific research organizations, physical culture organizati...

This work evaluates sperm head morphometric characteristics in adolescents from 12 to 18 years of age, and the effect of varicocele. Volunteers between 150 and 224 months of age (mean 191, n = 87), who had reached oigarche by 12 years old, were recruited in the area of Barranquilla, Colombia. Morphometric analysis of sperm heads was performed with principal component (PC) and discriminant analy...

purpose : this study intended to the effect of exercise protocol on 11 – 13 years old students’ dynamic balance while walking on balance beam. materials and methods: 30 non-athlete male students were equally and randomly assigned to an experimental (weight: 400.43 ± 8.34; height: 148.20 ± 6.87) and a control group (weight: 425.56 ± 7.25; height: 148.46 ± 7.28). the experimental group participat...

the nonlinear static procedures (nsps) proposed by design codes do not lead to reliable results especially for tall buildings. they generally provide inconsistent estimates of inelastic seismic demands, especially for the top floors due to their inabilities in considering the higher modes effects. in this paper, a new enhanced pushover procedure is proposed which is based on the envelope of the...

The attempt to achieved the goal could be through using artificial insemination (AI) by frozen semen. This study aims evaluate effect of breed on sperm motility Madura, Bali bulls and Bos taurus experiment used local bull semen (Madura breeds) (Simmental Limousin produced Singosari’s center. Sperm evaluation was conducted computer-assisted analysis (CASA, Spermvision, Minitube®, Germany). analy...
