Measurement of nitric oxide (NO) generation rate by chloroplasts employing electron spin resonance (ESR)
(Humana Press, 2016-04)
Chloroplasts are among the more active organelles involved in free energy transduction in plants (photophosphorylation). Nitric oxide (NO) generation by soybean (Glycine max, var ADM 4800) chloroplasts was measured as an ...
Collapse of the G d 3 + ESR fine structure throughout the coherent temperature of the Gd-doped Kondo Semiconductor CeF e 4 P 12
(American Physical Society, 2016-12-15)
Recent experiments on Gd3+ electron-spin resonance (ESR) in the filled skutterudite Ce1−xGdxFe4P12(x≈0.001), at temperatures where the host resistivity manifests a smooth insulator-metal crossover, provide evidence of the ...
ESR characterization of thallium(III)-mediated nitrones oxidation
(Elsevier Science Sa, 2009-05)
We characterized the reactions between Tl (III) and the usual nitrone spin traps (DMPO, POBN, and PBN). The ESR signal obtained with DMPO corresponded to DMPOX which was avoided neither by the enzymes superoxide dismutase ...
Exchange mechanism for electron paramagnetic resonance of individual adatoms
(American Physical Society, 2017-11)
We propose a universal mechanism that makes it possible to drive an individual atomic spin using a spin-polarized scanning tunnel microscope (STM) with an oscillating electric signal. We show that the combination of the ...
A deregulated expression of estrogen-target genes is associated with an altered response to estradiol in aged rats perinatally exposed to Bisphenol A
(Elsevier Ireland, 2016-02)
Here we assessed the effects of perinatal exposure to bisphenol A (BPA) on the uterine response to 17bestradiol(E2) in aged rats. Pregnant rats were orally exposed to 0.5 or 50 mg BPA/kg/day from gestationalday 9 until ...
Landscape Evolution of Southern Patagonia
(E Schweizerbartsche Verlags, 2000-12)
Investigations have been focused on the glacial history and valley development in the region of the terminal basins Lago Argentino, Lago Viedma and the adjacent Río Santa Cruz and Río Shehuen Valleys, as well as on the ...
Regarding the measurement of microviscosity in lipid bilayers by EPR
(Elsevier Science, 2019-09)
Simulations of electron paramagnetic resonance spectra of stearic acid spin labels in lipid bilayers are used to illustrate the fact that the apparent order parameter Sapp calculated from the spectral shape does not coincide ...
Male mammary gland development and methylation status of estrogen receptor alpha in Wistar rats are modified by the developmental exposure to a glyphosate-based herbicide
(Elsevier Ireland, 2019-02)
Postnatal treatment with glyphosate-based herbicides (GBHs) induces endocrine-disrupting effects on the male rat mammary gland. In this study, the effects of developmental exposure to GBH on mammary gland growth and ...
Single spin resonance driven by electric modulation of the g-factor anisotropy
(American Physical Society, 2019-12)
We address the problem of electronic and nuclear spin resonance of an individual atom on a surface driven by a scanning tunneling microscope. Several mechanisms have been proposed so far, some of them based on the modulation ...
Electrochemical behaviour of methylene blue in non-aqueous solvents
(Pergamon-Elsevier Science Ltd, 2015-05)
The electrochemical behaviour of methylene blue in solution of non-aqueous solvents with different supporting electrolytes was studied by cyclic voltammetry. Dye electro-reduction presents two well-defined processes of ...
