A scheme of the processes in Fenton solution with various substances is offered, and the channels of light formation registered by the luminometer are analyzed. Under the proposed scheme we discuss the possibilities of studying the properties of antioxidants and prooxidants. Oxidation of alanine, albumin and sodium oxalate have been taken as an example. The properties of ascorbic acid and the mechanism of display of its oxidant and prooxidant properties are analyzed herewith. Methodical questions of the chemiluminescence research in Fenton solution such as the selection of reagents concentration, water preparation and the effect of the background radiation have been considered in this study as well
HLA-I depletion does not preclude hESC differentiation into cardiac or hepatic lineages. This methodology can be used to engineer tissue from nonautologous hESC sources with improved immunocompatibility.
Generators of spark discharge in air have been developed, where the active factors affecting the object are plasma radiation and the active species formed in the discharge that diffuse to the surface of the object. The first effects observed in the water sample immediately after treatment are a decrease in pH and the formation of nitrous acid. In the experiments, two types of generators are used, which, in the water after treatment, yield a minimum pH value and a maximum concentration of nitrous acid. Processing was carried out in two modes. The first mode is with a discharge cavity completely opened in the direction of the sample (with light). The second mode is with a direction on the sample overlapping with an opaque insert (without light), but with the ability to freely diffuse gaseous products to the surface of the sample. Water samples are observed for 14 days after treatment. The products formed under the action of a low pressure mercury lamp (λ=253.7 nm) and plasma radiation are compared. The mechanism of generation of the active species in the discharge itself, which can diffuse to the sample surface and be absorbed by water, and species formed directly in water under the action of plasma radiation are considered. The role of plasma radiation in the formation of active species in water is analysed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
