Possible Interaction: Dietary Fiber and Hydrogen Peroxide

“Treatment with H2O2 increased the number of fiber cells undergoing apoptosis, and this increase was augmented with dominant-negative mutants that disrupted both hemichannels formed from Cx46 (also known as GJA3) and Cx50, while Cx50E48K, which only impairs gap junctions, did not have such an effect.”

“Exposure of intact muscle fibres to the oxidant hydrogen peroxide ( H2O2 ) affects mainly the myofibrillar function, where an initial increase in Ca2+ sensitivity is followed by a decrease.”

“These findings indicate that natural fibres generate more H2O2 and OH.”

“They also suggest that the natural fibres , amosite, crocidolite, antophyllite, erionite, and wollastonite may act catalytically in the dissociation of H2O2 to OH.”

“In contrast, incubation of fibres with 50 μm H2O2 sped up the development of Ca2+ sparks and increased their frequency.”

“Treatment with 1 mm H2O2 also increased the peak force of low [caffeine] contracture by ∼45 % in both fibre types compared to control (P < 0.01), which could be partly reversed following treatment with 10 mm dithiothreitol (DTT).”

“ Total fiber (TF) and NDF concentrations of all treatment residues were increased (P less than .05) over control substrates by AHP because of greater losses of cell solubles than of cell wall constituents.”

“The removal rate of impurities and the fineness of lotus fibres are improved after they are treated with hydrogen peroxide.”

“When corn fiber was pretreated with alkaline hydrogen peroxide , up to 429 mg of reducing sugars were released per gram of corn fiber.”
