Kinetics of the reaction of CO3 center dot-(H2O)(n), n=0, 1, 2, with nitric acid, a key reaction in tropospheric negative ion chemistryA significant fraction of nitrate in the troposphere is formed in the reactions of HNO3 with the carbonate radical anion CO3 center dot- and the mo...
ROS accumulation after 3 h post AaT treatment without significant alteration in\({{\rm{O}}}_{2}^{\cdot -}\)generation indicates the direct generation of H2O2. Various oxidases such as amino-acid oxidase, glucose oxidase, glycolate oxidase, and sulfite oxidase generate H2O2by hyper-oxidation ...
According to the previously article [40], the rice variety Zhendao 88 did carry a resistant allele of STV11, which encoded a sulfotransferase that catalyzes the conversion of salicylic acid into sulphonated SA, confers resistance in RSV. It has also been reported that NO is required for the ...
Iron is an essential micronutrient for plants as it involves in several important physiological processes. Understanding iron homeostasis in plants is pivo
The UPS-inhibited cells could be rescued by the addition of single amino acid ar- ginine, emphasizing the crucial function of UPS in NO production in iron-deficient T. vaginalis. In other words, this result demonstrates that NO is a pivotal molecule for cell survival when T. vaginalis ...
Tissues were fixed in formalin or HOPE (HEPES–glutamic acid buffer–mediated organic solvent protection effect; DCS Innovative Diagnostic Systems) and embedded in paraffin. An antigen retrieval procedure was performed with ER2 buffer (Leica Biosystems), and sections were stained with rat anti-mouse ...
