carnation (dianthus caryophyllus l.) is one of the most important cut flowers in the world. themajority of thecarnation cultivars are sensitive to ethylene which affected the physiological and biochemical postharvest characteristics of these flowers.applying inhibitors of biosynthesis and action of ethylene is important factor to protect the display quality and extend postharvest life. in order...

background in a severe oxidative stress condition, balance of oxidant-anioxdiant system of the body breaks down, which is in order to produce more oxidants and, after that, important macromolecules such as dna undergo irreversible changes. there are reports indicating the therapeutic effects of the date. this study was aimed to evaluate the effect of date kernel`s on antioxidant capacity and th...

in order to study the effect of salicylic acid on antioxidant enzymes activity such as peroxidase (pod), gayacol peroxidase (gpx) and poly phenol oxidase (ppo), chlorophyll a, b and carotenoid in coriander, this study was done as completely randomized whit three replication in biocenter of zabol university, 2014. salicylic acid was in four level (0, 1, 1.5 and 2 mm). in comparison with control,...

Magnetic nanoparticles (MNPs) have emerged as a promising material in disease diagnostics due to their potential enhance detection sensitivity, facilitate concentration and purification of target substances diverse samples, enable favorable color-based detection. In this study, antibody-conjugated MNPs were successfully synthesized validated through two appropriate methods: the measurement MNPs...

Synthesis, structure and antioxidant activity of new cyclohexene-fused spiroselenuranes and a spirotellurane is reported. Oxidation reactions of bis(o-formylcyclohex- 1-ene)selenide/bis(2-hydroxymethylcyclohex-1-ene)selenide provide the corresponding spiroselenuranes. The glutathione peroxidase-like activity of the newly synthesized compounds has been evaluated.

Nanozymes are defined as mimic enzymes with both unique nanostructures and catalytic activity. Inspired by natural enzymes, herein, we reported a dual-functional nanozyme of Au/Cu hierarchically organized particles (Hops) excellent polyphenol oxidase-like (PPO-like) peroxidase-like (POD-like) activities, which could rapidly oxidize refractory toxic phenolic pollutants serve sensitive tool to de...
