Kinetic Model of Biphasic Character of Catalyse Inhibition

Nonlinear Analysis, 2003
A mathematical model of kinetics of fungal catalase inhibition with hydroxylamine in presence of substrate (hydrogen peroxide) has been developed. The scheme includes an intermediate formation and slow reversible native enzyme production.

Pyrite/H2O2/hydroxylamine system for efficient decolorization of rhodamine B

Water Science and Technology, 2021
To improve the efficiency of the Fe(II)/Fe(III) cycle and continuous reactivity of pyrite, a pyrite/H2O2/hydroxylamine (HA) system was proposed to treat rhodamine B (RhB).

Dissolved Nitrous Oxide and Hydroxylamine in the South Yellow Sea and the East China Sea During Early Spring: Distribution, Production, and Emissions

Frontiers in Marine Science, 2021
Coastal marine systems are active regions for the production and emission of nitrous oxide (N2O), a potent greenhouse gas. Due to the inherently high variability in different coastal biogeochemical cycles, the factors and mechanisms regulating coastal ...

Spores of Clostridium engineered for clinical efficacy and safety cause regression and cure of tumors in vivo. [PDF]

, 2014
Spores of some species of the strictly anaerobic bacteria Clostridium naturally target and partially lyse the hypoxic cores of tumors, which tend to be refractory to conventional therapies. The anti-tumor effect can be augmented by engineering strains to

Molecular Probes for Evaluation of Oxidative Stress by In Vivo EPR Spectroscopy and Imaging: State-of-the-Art and Limitations

Magnetochemistry, 2019
Oxidative stress, defined as a misbalance between the production of reactive oxygen species and the antioxidant defenses of the cell, appears as a critical factor either in the onset or in the etiology of many pathological conditions.

2-aminophenols containing electron-withdrawing groups from N-aryl hydroxylamines [PDF]

, 2010
Reaction of substituted N-aryl hydroxylamines with methanesulfonyl chloride, p-toluenesulfonyl chloride, or trifluoromethanesulfonic anhydride under basic conditions leads to the rearranged 2-aminophenols (45-94%).

The two-photon reversible reaction of the bistable jumping spider rhodopsin-1 [PDF]

, 2019
Bistable opsins are photopigments expressed in both invertebrates and vertebrates. These light-sensitive G-protein-coupled receptors undergo a reversible reaction upon illumination.
