background: there are controversial reports about the exact mechanisms of lead-induced hypertension, but many factors such as alteration in the responsiveness of cardiovascular system to endogenous substances including catecholamines could be one of the mechanisms involved. in present study, the effect of exposure to 100 ppm lead acetate by drinking water (in the periods of 4, 8 and 12 weeks) o...

abstract— in the present study, genetic programming (gp) as a completely different approach in comparison with conventional methods, based on the imitation of natural evolution of living organism is proposed for the prediction of cellulose acetate (ca) polymeric membrane characteristics. the membrane preparation parameters of polymer concentration, additive concentration and coagulation bath te...

introduction: wistar rats are an outbred strain of albino rats belonging to the species rattus norvegicus. histopathological studies on the testis was carried out to determine the effects of heat and lead on male fertility by evaluating some andrological parameters of the wistar rat such as morphology of spermatozoa, sperm count and motility. the main objective of this research was to compare t...

calcium acetate is used as an oral phosphate binder to control hyperphosphatemia in patients with chronic renal failure. compared to calcium carbonate, control of hyperphosphatemia can be achieved at lower calcium administration with calcium acetate which likely reduces the risk of hypercalcemia. in this study, various formulations of calcium acetate tablets were prepared and their disintegrati...
