Spin Trapping: An Essential Tool for the Study of Diseases Caused by Oxidative Stress
(Bentham Science Publ, 2015)
Electron spin resonance (ESR), called also electron paramagnetic resonance (EPR) together with the spin trapping technique, has allowed us to study and understand how free radicals are involved in various pathologies. In ...
Substituent effect on the rate of the hydroxyl and phenyl radical spin trapping with nitrones
(CHEMICAL SOC JAPAN, 2002-09)
Hydroxyl and phenyl radical spin trapping rates by alpha-phenyl-N-t-butylnitrone (PBN, N-benzylidene-t-butylamine N-oxide) and its analogs were determined using a competitive trapping method. Hydroxyl radical was generated ...
Saproxylic Beetle Assemblage Selection as Determining Factor of Species Distributional Patterns: Implications for Conservation
(Oxford Univ Press, 2016)
The knowledge of the distributional patterns of saproxylic beetles is essential for conservation biology due to the relevance of this fauna in the maintenance of ecological processes and the endangerment of species. The ...
Identification of the transition state for fast reactions: The trapping of hydroxyl and methyl radicals by DMPO - A DFT approach
(Elsevier Inc., 2014)
Up to date, attempts to locate the transition state (TS) for the trapping reaction between ̇OH and ̇DMPO have been unsuccessful, and the lack of molecular mechanisms by which ̇OH binds to the spin-trap constitutes a question ...
Dimensional crossover for the Bose-Einstein condensation
(Sociedad Mexicana de Fisica, 1998)
We study Bose-Einstein condensation (BEC) for a non-interacting gas in a very anisotropic trap. Therefore, at enough small temperatures some degrees of freedom "freeze", thus reducing the "effective" dimensionality of the ...
Applications of electron spin resonance and spin trapping in tropical parasitic diseases
(2006)
Free radicals may be reaction intermediates in biological systems in more situations than are presently recognized. However, progress in detecting such species by Electron Spin Resonance (ESR) has been relatively slow. ESR ...
New heteroaryl nitrones with spin trap properties: Identification of a 4-furoxanyl derivative with excellent properties to be used in biological systems
(ELSEVIER, 2010)
A new series of heteroaryl nitrones, 1–7, bearing furoxanyl and thiadiazolyl moieties, were evaluated for
their free radical-trapping properties. The physicochemical characterization by electron paramagnetic
resonance ...
Nitrones: a potential new alternative as therapeutic agents
(Bentham Science Publishers Ltd., 2017)
Background: Nowadays, nitrones are the most used spin traps to characterize free radicals in biological systems due to the versatility and variety depending on the types of radicals to study and that the half-lives of the ...
Bone resorptive activity in symptomatic and asymptomatic apical lesions of endodontic origin
(Springer, 2017)
The aim of this study is to assess the levels and diagnostic accuracy of a set of bone resorption biomarkers, including TRAP-5, RANKL, and OPG in symptomatic and asymptomatic apical lesions and controls.
Apical tissues ...
