In spite of the pathological significance of oxidation of plasma lipids, no method is currently available for the evaluation of the susceptibility of these lipids to oxidation in unfractionated plasma. Here we demonstrate that copper-induced oxidation of diluted plasma, in the presence of citrate can be monitored continuously by recording the absorbance at 245 nm. The kinetics of accumulation of oxidation products in unfractionated plasma is a sum of lipid oxidation products obtained in low and high density lipoproteins isolated from the same p...

The treatment of enrofloxacin synthetic wastewaters using conductive-diamond electrochemical oxidation (CDEO), ozonation and Fenton oxidation has been studied. Results show that the three technologies can reduce the organic content of enrofloxacin synthetic wastewaters but with different performances. CDEO was the most efficient technology in terms of mineralization but not on COD removal, which was more efficiently achieved by ozonation. This indicates that ozonation is efficient in the breakage of the complex molecules but not on the removal ...

In this paper, the application of Fenton and Oxone/Co(2+) oxidation processes for landfill leachate treatment was investigated. The removal of the chemical oxygen demand (COD), suspended substances (SS) and the color of the landfill leachate by Fenton oxidation to that by Oxone/Co(2+) oxidation were compared under optimal operational conditions. For Fenton oxidation process, the optimal conditions were determined as: [H(2)O(2)]=80 mmol L(-1), [H(2)O(2)]/[Fe(2+)]=2.0, initial pH=2.5, reaction temperature=37.5+/-1 degrees C, reaction time=160 min...

The stratum corneum is located at the interface between body and environment and thus is constantly exposed to a pro-oxidative environment. Previously, we have demonstrated that stratum corneum lipids are targets of oxidative stress induced by ozone and by ultraviolet A and B exposure. Here, we employed an immunoblotting technique to detect protein oxidation in human stratum corneum obtained by tape stripping. After lysis, protein carbonyl groups were measured by derivatization with dinitrophenylhydrazine, separation by sodium dodecylsulfate-po...

Immediately after birth, glycolysis and lactate oxidation are the major source of ATP production in the rabbit heart. Although the ability of heart to oxidize fatty acid increases within days, glucose oxidation rates remain low in the first week after birth. To further examine the changes in energy substrate use in the newborn period, we developed a right and left ventricular isolated working heart model, in which 2-wk-old rabbit hearts were perfused with buffer containing 11 mM glucose, 0.8 mM palmitate, 0.5 mM lactate, and 100 microU/mL insul...

We investigated the influence of glycated low density lipoprotein (LDL) for vascular smooth muscle cell (SMC) proliferation or injury. We utilized glycated, slightly oxidized LDL (GLDL-LOX), glycated, auto-oxidized LDL (GLDL) and glycated, metal-induced extensively oxidized LDL (GLDL-OX) to examine the effect of glycation itself or combined glycation and oxidation on SMC. GLDL-LOX induced SMC proliferation and migration, and increased the number of platelet-derived growth factor receptor, beta subunits, (PDGF-R) positive SMC. Also, GLDL-LOX pro...

The purpose of this study was to understand better the factors providing oxidation resistance to human low-density lipoprotein (LDL). Therefore, the susceptibility to copper-induced in vitro oxidation of LDL from vitamin E deficient patients and normal healthy subjects was studied. Surprisingly, the LDL of vitamin E deficient patients appeared less susceptible to oxidation than control LDL. Both oxidation rate and extent of oxidation, measured as diene production, were reduced when compared to control LDL. The lag time, a measure of resistance ...

Catalytic abatement of solutions of 1,000 mg/L in phenol, ortho and para nitrophenol and ortho and para cresols was acomplished by using two catalytic systems. Fenton's reagent was used at 50 degrees C by adding 10 mg/L of ferrous cation and different dosages of H2O2. The mixture was reacting isothermically in a batch way during 3 hours. Catalytic wet oxidation (CWO) was carried out by using a commercial Activated Carbon, Industrial React FE01606A, CWO runs were carried out in a fixed bed reactor (FBR) with concurrent upflow. Temperature and ox...

The susceptibility of carbon fibers and interphases to oxidation can prohibit the use of carbon fiber reinforced composites in applications with oxidizing environments at elevated temperatures. C/SiC composites and their constituents were studied in different tests in oxidizing environments to help identify the limitations of the basic C/SiC material system and point to potential protection schemes that can be used to inhibit oxidation of the carbon constituents. Thermogravimetric analysis (TGA) tests were conducted on C/SiC composites to study...
