Thorough removal of silicic acid from treated water, as a water pretreatment procedure, is essential for the prevention silica deposits on anion exchange resins and reverse osmosis membranes. In this study, thorough was achieved using Tiron (1,2-dihydroxy-3,5-benzendisulfonate) combined resin. column experiment, it confirmed that could be removed below detection limit molybdenum-blue methods. T...

Recent research found that Tiron was an effective antioxidant that could act as the intracellular reactive oxygen species (ROS) scavenger or alleviate the acute toxic metal overload in vivo. In this study, we investigated the inhibitory effect of Tiron on matrix metalloproteinase (MMP)-1 and MMP-3 expression in human dermal fibroblast cells. Western blot and ELISA analysis revealed that Tiron i...

O3 is the major component of photochemical oxidants and gives rise to visible injuries on plant leaves. In O3-exposed plants, O2- is produced before the formation of the injury, but the role that O2- plays in plant response to 03 exposure is still unknown. To clarify its role, we observed the behavior of plants during O3 exposure after pretreatment with tiron, which is an O2- scavenger. When ti...

Although the widespread use of titanium dioxide nanoparticles (TiO2 NPs), few studies were conducted on its hazard influence on human health. Tiron a synthetic vitamin E analog was proven to be a mitochondrial targeting antioxidant. The current investigation was performed to assess the efficacy of tiron against TiO2 NPs induced nephrotoxicity. Eighty adult male rats divided into four different ...

In the present study an attempt has been made to evaluate the effect of Tiron along with Zinc, Selenium and Vitamin E against vanadium intoxication in female albino rats. Toxicant caused significant increase in the activities of serum transaminases, serum alkaline phosphatase and lactate dehydrogenase. Significant decrease was observed in blood sugar, serum albumin and triglyceride levels where...

Recent evidence suggests that increased inactivation of endothelium-derived nitric oxide (NO) by oxygen free radical (OFR) formation is involved in the pathogenesis of endothelial dysfunction in heart failure (HF). However, it is unclear whether increased OFR limits coronary flow reserve in HF. To test this hypothesis, we examined the effects of antioxidant therapy on coronary flow reserve in a...

Recent evidence suggests the possibility that enhanced inactivation of endothelium-derived nitric oxide (NO) by oxygen free radical (OFR) may cause endothelial dysfunction in heart failure (HF). To test this hypothesis, we examined the effect of antioxidant therapy on endothelium-dependent vasodilation of the coronary circulation in a canine model of tachycardia-induced HF. Endothelium-dependen...

The equilibrium constants and kinetics for the complexing of aqueous iron(m) by 2,3dihydroxybenzoic acid (DHB) and 1,2-dihydroxy-3~-benzenedisulfo~te (Tiron) have been studied with iron(IIl) in excess over ligand. Formation constant comparisons indicate that DHB complexes in a mode analogous to salicylate. The reaction rate has the hydrogen ion dependence typical for iron(m) complexation, but t...
