TL;DR: Failure to require cysteine, glutathione, or manganese ions, and to be inhibited by aureomycin and other chelating agents, as well as its complete inhibition by oxygen shows that the mammalian system differs from the bacterial system of Escherichea coli.
Abstract: A nitro reductase system found predominantly in the liver and kidney of rabbit but also present to a small degree in other tissues, reduces chloramphenicol, p -nitrobenzoic acid and a variety of other aromatic nitro compounds to the corresponding amines. The nitro reductase system is found both in the soluble fraction of the cells and in microsomes. Either TPNH or DPNH can act as hydrogen donors but the former seems to be considerably more active. The system includes a flavoprotein whose prosthetic group can be replaced by FMN, FAD or riboflavin. An added excess of flavins accelerates the normal rate of reduction, perhaps by acting as an artificial electron carrier between the reduced pyridine nucleotide and the substrate.
Failure to require cysteine, glutathione, or manganese ions, and to be inhibited by aureomycin and other chelating agents, as well as its complete inhibition by oxygen shows that the mammalian system differs from the bacterial system of Escherichea coli .
There is considerable species difference in the activity of the reductase, the enzyme being highly active in mice, guinea pigs and rabbits and less so in rats and dogs.

TL;DR: In this article, the intercalation process was achieved by anion exchange of nitrates in the host material, Ca2Al(OH)6NO3, nH2O (CaAl LDH), which was prepared by a coprecipitation technique.

TL;DR: Hydrogen sulfide was determined with N-ethylmaleimide, p-chloromercuribenzoate, and 5,5′-dithiobis-(2-nitrobenzoic acid) (DTNB) and in the presence of proteins containing different amounts of sulfhydryls reacting with DTNB, 78 to 94% of the added hydrogen sulfide could be recovered.

TL;DR: A simply prepared gold nanoparticle-based sensor, 5,5'-dithiobis (2-nitrobenzoic acid) (DTNBA)-modified gold nanoparticles, was prepared to explore the sensitive and selective detection of metal ions using a colorimetric technique.
Abstract: A simply prepared gold nanoparticle-based sensor, 5,5′-dithiobis (2-nitrobenzoic acid) (DTNBA)-modified gold nanoparticles, was prepared to explore the sensitive and selective detection of metal ions using a colorimetric technique. The selective detection of trace levels (93.6 ppb) Cr3+ in aqueous solution was achieved over 15 other metal ions. The functionalized gold nanoparticles became aggregated in solution in the presence of Cr3+ by an ion-templated chelation process, which caused an easily measurable change in the extinction spectrum of the particles and provided an inherently sensitive method for Cr3+ detection in aqueous solution.

TL;DR: Results suggest that distinct cellular components mediate activation versus deactivation of the fat cell hexose transport system, and N-Ethylmaleimide, which effectively penetrates fat cells, inhibits both processes while the layer, more polar dithio(bis)nitrobenzoic acid blocks activation but not de activation of this transport system.
