Effect of different concentrations of Zinc and their interaction with Sodium nitroprusside (SNP) on physiological and biochemical parameters of Plantago major L. Sara Nasiri Savadkoohi1*, Sakineh Saeidi-sar2 Abbas Ali Dehpour3 and Hossein Abbaspour1
Zinc is a necessary micronutrient in plants whose deficiency can alter essential functions in plant metabolism. High concentrations of Zn can be potentially toxic to plants causing phytotoxicity by the formation of reactive oxygen species. On the other hand, sodium nitroprusside (SNP), a donor of nitric oxide (NO) can protect cells from oxidative damage produce by reactive oxygen species. In th...
متن کاملStudies on Genotoxic Effects of Mobile Phone Radiation on A375 Cells
Introduction: Radiation from cell phones has been associated with an increased risk of cancer. The literature has reported evidence of certain biological effects resulting from exposure to various wavelengths, doses, and intensities of radiofrequency radiation. The present study aimed to evaluate the possible adverse effects of radiation from a GSM mobile phone operating at 900 MHz on human mel...
متن کاملReactive Oxygen Species and Antioxidant in Seminal Plasma and Their Impact on Male Fertility
Spermatozoa generate reactive oxygen species (ROS) in physiological amounts which play a role in sperm functions during sperm capacitation acrosome reaction (AR) and oocyte fusion. In addition damaged sperm are likely to be the source of ROS. The most important ROS produced by human sperm are hydrogen peroxide superoxide anion and hydroxyl radicals. Besides human seminal plasma and sperm posses...
متن کاملInvestigation of toxicity of zinc oxide nanoparticles synthesized by olive extract on growth and pigments in Borago officinalis
The synthesis of metal nanoparticles has attracted the attention of scientists in various fields, particularly in the chemical, physical, biological and medical sciences. Using extract of plant for nanoparticle synthesis can be advantageous over other biological processes because it eliminates the elaborate proc...
متن کامل7, 8-Dihydroxyflavone Protects an Endothelial Cell Line from H2O2 Damage
7, 8-dihydroxyflavone (7, 8-DHF), a selective agonist for TrkB receptors, has been well studied for its neurotrophic functions. However, its roles outside the neural tissues have scarcely been studied as yet. In this study, we investigated the protecting roles of 7, 8-DHF in EA.hy926 cells, a human umbilic vein endothelial cell line which was exposed to hydrogen peroxide (H2O2). We found that 7...
