Synthetic nitrogen fertilizers can contribute to environmental hazards. Moreover, their manufacturing is an energy-intensive process which causes greenhouse gas emissions, lead climate change. Therefore, it should evaluate the possibility use organic sources such as Azolla a partial substitute for synthetic in cultivation, this may reduce cost of fertilizer inputs, and promote sustainable agric...

the aim of this study was to investigate the effect of adding different levels of zinc sulfate in semen extender on bovine sperm quality during cryopreservation. semen was collected from 4 holstein bull twice a week and the proper samples were pooled. semen were allocated to four extender treatments consisted of 0, 50, 100, 150 µm of zinc sulfate in 5 replicates and then, were frozen. post-thaw...

We investigated the effect of locally applied zinc on the healing of partial-thickness skin wounds in the domestic pig using two zinc compounds (zinc oxide and zinc sulfate) in two different vehicles (a gauze compress and a collagen sponge). The rate of re-epithelialization was determined morphometrically 48 and 64 hr after infliction of standardized square wounds (4.8 cm2 and 400-microns deep)...

Zinc sulfate is a known olfactory toxicant, although its specific effects on the olfactory epithelium of zebrafish are unknown. Olfactory organs of adult zebrafish were exposed to zinc sulfate and, after 2, 3, 5, 7, 10 or 14 days, fish were processed for histological, immunohistochemical, ultrastructural, and behavioral analyses. Severe morphological disruption of the olfactory organ was observ...
