Mechanisms and pathways of ethidium bromide Fenton-like degradation by reusable magnetic nanocatalysts

Degradation of Azo Dye Reactive Black 5 and Acid Orange 7 by Fenton-Like Mechanism

Efficient Fenton like degradation of Methylene blue in aqueous solution by using Fe3O4 nanoparticles as catalyst

Fe3O4 nanoparticles were prepared hydrothermally and characterized by X-Ray diffraction spectroscopy (XRD), and scanning electron microscopy (SEM). It was found that these nanoparticles can act as an efficient catalyst in the degradation of Methylene blue dye in aqueous solution in a Fenton like system in presence of 30% perhydrol. Uv-Vis spectroscopy was used to determine the concentration of ...

A novel and robust conditioning lesion induced by ethidium bromide.

Molecular and cellular mechanisms underlying the peripheral conditioning lesion remain unsolved. We show here that injection of a chemical demyelinating agent, ethidium bromide, into the sciatic nerve induces a similar set of regeneration-associated genes and promotes a 2.7-fold greater extent of sensory axon regeneration in the spinal cord than sciatic nerve crush. We found that more severe pe...

Modulation of petite induction by low concentrations of ethidium bromide.

When starved, exponential phase cells of Saccharomyces cerevisiae are exposed to lo-25 UM ethidium bromide in buffer, the proportion of respiration deficient mutants in the population exhibits a rapid increase, followed by a pronounced decrease. This "self-rescue" by the mutagen can be dissociated from and studied independently of its mutagenic action and is shown to exhibit different requireme...

Evaluation of HLA-DR typing by ethidium bromide fluorescence.

Sixty individuals were typed for D-related human leukocyte antigens (HLA-DR) using two methods: the standard eosin exclusion method and a recently described one-color ethidium bromide technique. As a result, 88 of the 90 DR antigens detected by the standard technique were also detected by one-color fluorescence (sensitivity = 97.8 percent). However, of the 99 DR antigens identified by ethidium ...
