Introduction: Increase in enamel surface roughness after bleaching is one of its major side effects. The purpose of this study is to compare changes in enamel surface roughness following bleaching with home versus office bleaching agents. Materials and Methods: In this experimental study, forty human sound premolar teeth were divided into 4 groups, randomly. Ten teeth were bleached using hydrog...

recently, application of sa has increased to improve plants resistance to stresses such as drought. hence, to investigate sa effects on morphophysiological characteristics of fennel(foeniculum vulgare mill.) under drought stress, a split plot experiment based on latin square design with three replications was carried out at research farm of shahid bahonar university of kerman in 2012. three lev...

 Background and purpose: About 50% of infertility in couples is related to male factors and oxidative stress is one of the main causes of infertility in men. Hydrogen peroxide has an adverse effect on male reproductive system due to its free radicals. Spirulina and phycocyanin are known to have antioxidant properties and can modify stressors. Materials and methods: In this experimental study, ...

Horseradish peroxidase-mediated oxidative cross-linking of a thiolated poly(ethylene glycol) is promoted in the absence of exogenous hydrogen peroxide, by adding a small amount of a phenolic compound under physiological conditions. The prepared hydrogel can encapsulate and release living mammalian cells.
