Lifespan and ROS levels in different Drosophila melanogaster strains after 24 h hypoxia exposure

open access: yesBiology Open, 2022
During recent decades, model organisms such as Drosophila melanogaster have made it possible to study the effects of different environmental oxygen conditions on lifespan and oxidative stress.

The Einstein-Podolsky-Rosen paradox: from concepts to applications [PDF]

open access: yes, 2008
This Colloquium examines the field of the EPR Gedankenexperiment, from the original paper of Einstein, Podolsky and Rosen, through to modern theoretical proposals of how to realize both the continuous-variable and discrete versions of the EPR paradox. We

EPR states and Bell correlated states in algebraic quantum field theory

open access: yes, 2013
A mathematical rigorous definition of EPR states has been introduced by Arens and Varadarajan for finite dimensional systems, and extended by Werner to general systems. In the present paper we follow a definition of EPR states due to Werner. Then we show

EPR Spectra from “EPR-Silent” Species:  High-Field EPR Spectroscopy of Aqueous Chromium(II). [PDF]

open access: yesInorganic Chemistry, 1998
High-field (up to 14.5 T) multifrequency (∼90−440 GHz) electron paramagnetic resonance (EPR) spectroscopy has been used to probe the non-Kramers, S = 2, Cr2+ ion in frozen aqueous solution, in the presence and absence of the glassing agent, glycerol. Solutions with both chloride and sulfate counterions were investigated.

Potentially Diagnostic Electron Paramagnetic Resonance Spectra Elucidate the Underlying Mechanism of Mitochondrial Dysfunction in the Deoxyguanosine Kinase Deficient Rat Model of a Genetic Mitochondrial DNA Depletion Syndrome [PDF]

open access: yes, 2016
A novel rat model for a well-characterized human mitochondrial disease, mitochondrial DNA depletion syndrome with associated deoxyguanosine kinase (DGUOK) deficiency, is described.

EPR on Flavoproteins [PDF]

open access: yes, 2014
Flavoproteins often employ radical mechanisms in their enzymatic reactions. This involves paramagnetic species, which can ideally be investigated with electron paramagnetic resonance (EPR) spectroscopy. In this chapter we focus on the example of flavin-based photoreceptors and discuss, how different EPR methods have been used to extract information ...

Silicon facilitates manganese phytoextraction by cucumber (Cucumis sativus L.)

open access: yesZaštita Materijala, 2016
The effect of excess nutrient levels of manganese (Mn, 50 and 100 mM) on the growth inhibition and the appearance of Mn-toxicity symptoms in the leaves was studied in cucumber plants (Cucumis sativus L. cv. Chinese long). Silicon (Si), when supplied as 1.

Entanglement properties of third harmonic generation via direct and cascaded parametric processes [PDF]

open access: yes, 2017
We compare the bipartite entanglement and EPR-steering properties of the two different schemes which produce third harmonic optical fields from an input field at the fundamental frequency. The first scheme uses second harmonic cascaded with sum-frequency
