Measuring the effects of the acute intake of natural products on human biomarker concentrations, such as those related to oxidation and inflammation, can be an advantageous strategy for early clinical research on an ingredient or product. 31 total healthy subjects were randomized in a double-blinded, placebo-controlled, acute pilot study with post-hoc subgroup analysis on 20 of the subjects. The study examined the effects of a single dose of a polyphenol-rich beverage (PRB), commercially marketed as SoZo®, on serum anti-inflammatory and antioxidant markers. In addition, phytochemical analyses of PRB, and in vitro antioxidant capacity were also performed. At 1 hour post-intake, serum values for 8-iso-PGF2-alpha and advanced oxidation protein products decreased significantly by 40% and 39%, respectively. Additionally, there was a trend toward decreased C-reactive protein, and increased nitric oxide levels. Both placebo and PRB treatment resulted in statistically significant increases in hydroxyl

The aim of this study was to compare the kinetics of the glycoxidation of bovine serum albumin (BSA) as a model protein by three sugars: glucose, fructose and ribose, using fluorometric measurements of the content of advanced glycation end products (AGEs), protein-bound fructosamine, dityrosine, N-formylkynurenine, kynurenine, tryptophan, the content of advanced oxidation protein products (AOPP), protein carbonyl groups, as well as thiol groups. Moreover, the levels of glycoalbumin and AGEs were determined by using an enzyme-linked immunosorbent assay. Based on the kinetic results, the optimal incubation time for studies of the modification of the glycoxidation rate by additives was chosen, and the effects of 25 compounds of natural origin on the glycoxidation of BSA induced by various sugars were examined. The same compounds were found to have different effects on glycoxidation induced by various sugars, which suggests caution in extrapolation from experiments based on one sugar to other sugars. From

Background: Methyl-thiophanate (MT), a fungicide largely used in agriculture throughout the world including Tunisia, protects many vegetables, fruits and field crops against a wide spectrum of fungal diseases. Oxidative stress has been proposed as a possible mechanism involved in MT toxicity on non-target organism.. Methods: In the present study, the effect of MT injected intraperitoneally to adult rats at 300 or 500 mg/kg of body weight was studied on blood, liver and kidney.. Results: Our results showed 3 days after MT injection, a significant decrease in hemoglobin and hematocrit values. A disruption in total white blood cells and platelets also occurred. Accordingly, an increased in malondialdehyde, H2O2 and advanced oxidation protein levels in liver and kidney were noted with the two doses. A significant change in plasma biomarkers and organ enzymatic and non-enzymatic activities were observed after MT treatment. The modifications in biochemical parameters were substantiated by ...

The generation of highly polluting leachate from Sanitary Landfills has prompted the development of technologies applicable to treatment of these liquids. The aim of this study was to determine the kinetics of adsorption of organic and inorganic matter contained in pre-treated leachate (by advanced oxidation by the Fenton reaction); after two adsorbents were used, first eggshell and then activated carbon. To determine the content of organic and inorganic matter COD was measured; this was the parameter for monitoring the kinetics. The leachate was subjected to advanced oxidation treatment by the Fenton reaction, then the adsorption process was conducted by batch, in two consecutive steps, the first step was the use of eggshell and the second step activated carbon. Due to the oxidation treatment the pH value decreased to 2, after the adsorption eggshell the pH increased to 6.9 and this was maintained in the treatment with activated carbon. The kinetics of adsorption of organic and

Water scarcity and water pollution is a worldwide problem and has driven research into eco-friendly and low-energy cost efficient remediation. The reuse of wastewater for non-potable purpose after proper treatment is the only sustainable solution to the problem. Advanced oxidation processes (AOP) based on the in-situ generation of hydroxyl radicals have been intensively investigated for this purpose as a treatment step to achieve wastewater reuse. The main degradation mechanism of AOPs is based on the reaction of hydroxyl radicals with dissolved organic matter. However, hydroxyl radicals follow unselective multi-step pathways, limiting their efficiency in complex environmental matrices. To overcome such limitations, AOP treatment, based on generation of sulfate radicals, has been developed and widely investigated. This current mini-review will cover the most recent developments regarding emerging contaminant removal, i.e., organic micropollutants, using sulfate radicals generated by active persulfate or
Electrical discharges in water are currently known as another reliable method to conventional advanced oxidation processes in treatment of drinking water or industrial water for public water supply system. Generation of nonthermal plasmas by electrical discharges in water, induces a variety of physical and chemical processes, which include, among others, formation of reactive molecules (H2O2, H2 a O2) and free radicals (OH·, H·, O· and HO2·). Previous researches showed that this products are very effective in removal of organic and microbial decontamination in water.. The aim of this thesis was to develop a deeper understanding of plasmachemical processes induced in water by pulsed corona discharges with the main focus on its oxidation-reduction properties and their application to the decomposition of resistant organic compounds in water. Discharge was generated in water using needle-to-plate electrode configuration. In the first part of thesis, the effect of conductivity solution, applied ...

Our advanced oxidation system uses patented reactor technology to combine ozone and hydrogen peroxide to produce hydroxyl radicals in a plug flow reactor.
Water is our most useful and necessary resource. It is also becoming a scarce resource in many parts of the world. Water borne diseases claim more lives and make more people sick than any other cause. As our population continues to increase and urbanize, clean water becomes more and more scarce. The pollutants in our water are also becoming more difficult to remove. Levels of antibiotics, pharmaceuticals, agricultural chemicals, and many other substances in our drinking water are all on the rise. It is clear that water issues are at the core of sustainability. Our research on water treatment methods, such as Advanced Oxidation Processes and membrane technologies, are at the forefront of the subject. BBISS director, John Crittenden, is the lead author of the classic text on the subject of water treatment.. ...

Alternative treatment methods, that is, advanced oxidation processes (AOPs), have been studied extensively during the last years: the most studied being ozonation and photocatalysis. Recently, the degradation of ibuprofen (IBP)-which is one of the top-ten drugs sold worldwide-by non‐thermal plasma has also been investigated. Approximately 15% of IBP is excreted unchanged or as its glucuronide and the rest is metabolized to several other compounds, including hydroxyl and carboxyl metabolites and their conjugates, which are also partly excreted. The relatively low excretion rate is balanced or even surpassed by the extensive consumption, and thus IBP has been detected in high concentrations in raw wastewater. IBP has also been found in surface water and is highly concentrated in seawater, especially in the Mediterranean Sea.. A team of researchers from the National Institute for Lasers and University of Bucharest in Romania set up a study to see how plasma could help with this problem: the team ...
