the objective of this research is to identify arabidopsis thaliana genes encoding acid phosphatases induced by phosphate starvation. multiple alignments of eukaryotic acid phosphatase amino acid sequences led to the classification of these proteins into four groups including purple acid phosphatases (paps). specific primers were degenerated and designed based on conserved sequences of paps isol...

introduction: the impact of chromium exposure was studied on liver, kidney, testis, spleen, cerebrum and cerebellum of male wistar rats (80-100 g body weight). material & method: it was observed that treatments of rats with chromium (i.p. at a dose of 0.8 mg / 100 g body weight per day) for a period of 28 days caused significant increase in chromium content while declining the body weight along...

backgrounds and aims: the purpose of this study was to examine the effects of potassium, sodium and zinc metal ions on ammonium sulfate fraction of acid phosphatase activity of orange fruit. materials and methods: acid phosphatase was extracted and purified from orange fruit and then various samples as well as a control sample were prepared in vitro. in addition to substrates, ions of potassium...

effects of gibberellic acid (ga) and abscisic acid (aba) on dormant and after-ripened wheat seed, cultivar rl4137, were studied. the aim of the study was to evaluate the effects of seed after-ripening in comparison with gibberellin application on breaking of seed dormancy. moreover, the effect of abscisic acid on dormancy induction was also evaluated. acid and alkaline posphatase activity of se...

The main role of cumulus cells (CC) is to provide nutritious materials for developing oocytes. Follicular fluid (FF) contains the enzyme acid phosphatase, which plays a role in ovulation and fertilization of oocyte. The objective of this prospective study was to evaluate the levels of acid phosphatase in FF and the rate of apoptosis in CC of fertilized and unfertilized oocytes in intracytoplasm...

introduction: the aim of this study was to evaluate the correlation between serum levels of ovarian and gonadotropin hormones, age and number of follicles with follicular alkaline and acid phosphatase activity in infertile women under controlled ovarian hyperstimulation. methods: after collection of follicular fluid and calculation of the number of follicles, the specific activity of alkaline (...

Background: Heavy metals such as cadmium (Cd2+) are natural components of the Earth's crust which can not be degraded or destroyed. Industrial, mining and agricultural activities, particularly the excessive use of phosphate fertilizers, have led to high levels of cadmium contamination at many locations worldwide. Some toxic effects of cadmium are due to its inhibition of various enzyme sys...
