(2022-05-04)
One-electron oxidation of alkylsulfinic acids has been of great interest for years as the reaction mechanisms are known to be quite elusive. We herein investigate the kinetics and mechanism of oxidation of an alkylsulfinic ...
Mechanism of the Outer-sphere Oxidation of Aqueous L-cysteine and of Iodide in Acetonitrile by a Series of Iron(III) Complexes
(2007-05-15)
Trace copper catalysis was observed in the oxidation of L-cysteine by [Fe(bpy)2(CN)2]+ and [Fe(bpy)(CN)4]- in anaerobic aqueous solution. The copper catalysis was effectively inhibited with the addition of dipicolinate ...
Mechanisms and Evolution of Disease Resistance in Birds
(2017-01-04)
Disease outbreaks in wildlife, agricultural animals, and humans have increased in both frequency and magnitude in recent decades, refocusing research efforts on understanding the factors that influence disease emergence. ...
Mechanisms and Kinetics of Proton-Coupled Electron-Transfer Oxidation of Phenols
(2011-11-28)
The kinetics of the aqueous oxidation of phenol by a deficiency of [IrCl6]2– has been investigated. The reaction initially produces [IrCl6]3– and phenoxyl radicals. The inhibition caused by [IrCl6]3– can be prevented by ...
Mechanisms and Performance Measures in Mastery-Based Incremental Repeated Acquisition: Behavioral and Pharmacological Analyses
(2009-09-10)
Pharmacological and behavioral determinants of learning were examined using a mastery-based incremental repeated acquisition procedure. A 60-minute session began with a one link chain (single lever-press) that incremented ...
Mechanisms Mediating Antidiabetic Effects of Serviceberry extracts, Curcumin, and Stilbenes
(2012-05-07)
Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia in which homeostasis of carbohydrate and lipid metabolism is improperly regulated by insulin. Hippocrates (460-377 B.C), said “Let food be ...
Mechanisms of Cytoplasmic Incompatibility Operon Horizontal Gene Transfer
(2023-07-27)
Transposable elements are responsible for vast genetic changes within the global ecosystem. It is observed that transposons can change the genetic makeup of an organism through the modification of the genome; such as the ...
Mechanisms of Olfaction in Parasitic Wasps: Analytical and Behavioral Studies of Response of a Specialist (Microplitis croceipes) and a Generalist (Cotesia marginiventris) Parasitoid to Host-Related Odor
(2011-07-27)
Parasitic wasps (parasitoids) are known to utilize as host location cues various types of host-related volatile signals. These volatile signals could be plant-based, originate from the herbivore host, or be produced from ...
Mechanisms of Olfaction in Parasitic Wasps: Neurophysiological and Neuroanatomical Studies of Olfaction in a Specialist (Microplitis croceipes) and a Generalist (Cotesia marginiventris) Parasitoid
(2012-12-06)
The success of parasitic wasps (parasitoids) in controlling pest populations depends on their ability to locate their hosts in a complex olfactory environment. Parasitic wasps are known to utilize various types of host-related ...
Mechanisms Underlying Myeloperoxidase Inhibition: Evaluating the Efficacy and Safety of Anti-inflammatory MPO Inhibitors Designed to Limit the Generation of Reactive Oxygen and Nitrogen Species
(2015-07-24)
Myeloperoxidase (MPO), a heme-containing peroxidase, plays a critical role in the innate immune response by producing hypochlorous acid. MPO-mediated oxidation is also associated with chronic obstructive pulmonary disease ...
