Role of reactive oxygen species in the renal fibrosis. (6/20)

Renal fibrosis is a common pathway of progressive renal diseases leading to end-stage renal disease regardless of the etiology. Accumulating evidence indicates that oxidative stress, resulting in generation of reactive oxygen species (ROS), plays a critical role in the initiation and progression of fibrotic diseases. Nicotinamide adenine dinucleotide phosphate (NADPH) oxidase is the predominant enzyme source for ROS generation and is now recognized as a key mediator of cell proliferation and matrix accumulation in renal disease. Multiple stimuli and agonists, such as transforming growth factor beta1, tumor necrosis factor, platelet derived growth factor, angiotensin II, hyperglycemia, oxidized low-density lipoprotein and albumin have been shown to alter the activity or expression of the NADPH oxidase and ultimately increase ROS production. ROS directly incites damage to biologically important macromolecules and leads to generation of the so-called advanced oxidation protein products (AOPPs) and advanced glycation end products, which are not only markers of oxidative stress but also cause renal injury. Targeting NADPH oxidase and/or reducing AOPPs production might be a novel strategy for the therapeutic intervention of variety of fibrotic kidney disorders.  (+info)

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

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 ...

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 ...
Degradation of hazardous organic compounds using ultrasound is an attractive advanced oxidation technology for wastewater treatment, and it is well known that the ultrasonic degradation reaction is enhanced by particle addition. In this study, the effects of ultrasonic irradiation conditions and particle addition on the degradation rate constant were investigated using pseudo-first-order chemical reaction model. Moreover, the application of this model to degradation of other organic compounds in the presence of particles by other research groups has been investigated. The degradation reaction was enhanced by particle addition, and the apparent degradation rate constant is proportional to the increase in amount of particle. In addition, the constant of proportionality is not influenced by degraded material and ultrasonic frequency. However, particle type influences the constant of proportionality ...
Pure water is never found in nature and it is increasingly rare to encounter a source of water that requires no treatment before being used for portable water supply. Conventional treatment methods are not effective for the degradation of toxic organic pollutants; hence other treatment techniques are necessary. One of the recent developments in this field is the Advanced Oxidation Process (AOP). In this Advanced Oxidation Process, photo catalysis is a technique which utilizes the solar radiation to treat the sewage with more organic contents. For the removal of organic waste form the sewage, oxidation reduction reaction is used and this reaction is accelerated using titanium dioxide as a strong oxidizing agent. Titanium di-oxide (TiO2) is widely used as a catalyst for this purpose, to oxidise or reduce the organic pollutants in wastewater. This paper deals with performance of the titanium dioxide under varying parameters of the sewage and its efficiency. The photo catalysis of sewage has been studied
It was studied the feasibility of a H2O2/UV AOP for tertiary treatment in a WWTP fed with municipal and textile wastewater (the latter about 30% as flow and 60% as COD load). The plant is located near Como (Italy), in a touristic area characterized by the presence of textile industries and by sensitive receiving water bodies. The effluents from the biological treatment is still coloured, with a scarcely biodegradable residual COD and contains surfactants in significant concentration. A pilot scale H2O2/UV advanced oxidation reactor was implemented after the biological treatment for assessing the possibility of substituting the existing tertiary coagulation-flocculation stage and for evaluating the upgrade of the UV disinfection to an H2O2/UV advanced oxidation treatment. Decolorization yields were monitored as a function of H2O2 and UV radiation dosages (H2O2: 0.1-2 g/L, UV radiation: 120-6,400 mJ/cm2). Surfactants, aldehydes and TOC removals were measured. Process parameters were optimized for ...
... Daewon Pak, Haemin Ku, Yongho Lee Graduate School of Energy and Environment, Seoul National University of Science and Technology, 232 Gongneungro, Nowon-gu, Seoul, Korea, [email protected] In recent years, photocatalytic oxidation processes have shown great potential as a low-cost, environmental friendly treatment technology in the water and wastewater industry [1, 2]. This oxidation technology has been widely demonstrated to have the ability to remove persistent organic compounds and microorganisms in water [3, 4]. The rationale for this advanced oxidation technology is based on the in-situ generation of highly reactive transitory species (i.e. OH, H2O2, O2, O3) for oxidation of refractory organic compounds and disinfection of water pathogens. A photocatalytic reactor employing TiO2 nanotubes grown on Ti plate was designed and operated. In order to synthesize TiO2 nanotubes on a Ti plate, self-organized oxide
Photocatalysis over semiconductors, mainly Ti02, has been employed and extensively studied over the past few decades (Malato et aI., 2009). The so-called first generation photocatalYSIS are characterised by their photoexcitation limited to the UV region of the solar spectrum. Nevertheless, many photocatalysts showed outstanding performance in decomposing a large number of pollutants of water and air. A number of water pollutants belong to the family of biorecalcitrant pollutants (non-biodegradable) and these include pharmaceutical and personal care products, industrial wastes, and a large number of pesticides/herbicides. Many of the emerging pollutants are resistant to conventional water treatment processes, noxious to the environment and some are classified as endoctine disrupting agents. The removal of non-biodegradable pollutants from wastewater poses a serious challenge for the water industry. Generally, advanced oxidation processes (AOP) are employed to achieve this goal. Heterogeneous ...
There is a growing concern about pharmaceuticals entering the aquatic environment. Many of these compounds cannot be removed completely in sewage treatment plants. To remove these unwanted medicines from water, oxidative degradation techniques may complement the current purification steps. In this paper we studied the effect of advanced oxidation on the cytostatic drug cyclophosphamide (CP) by comparing thermal plasma activation with UV/H2O2 treatment. Plasma activated water (PAW) contains highly reactive oxygen and nitrogen species (RONS) as a result of electric gas discharges in air over water. CP solutions in tap water were oxidized over a period of 120 min and subsequently analyzed by LC-MS/MS to measure the compound degradation. Plasma activation was applied at 50, 100, or 150 W electric power input and UV/H2O2 treatment was carried out by the addition of H2O2 and placing an UV-C source above the test solution for immediate irradiation. The oxidative degradation of CP in PAW resulted in a ...

DESCRIPTION (provided by applicant): Groundwater is one of the most important freshwater resources on this planet. However, contaminated groundwater has become an ever-increasing problem in the United State. Among the many types of contaminants, Volatile Organic Chemicals (VOCs) are a major concern and a potential human health threat for those who use groundwater for the supply of drinking water. Pump-and-treat technology is one of the most widely used groundwater remediation approaches, and can be effective when combined with other remediation methods, including Advanced Oxidation Technologies (AOTs). The Dense Medium Plasma (DMP) technology is a highly efficient AOT for treatment of VOCs in extracted groundwater. Compared to other existing AOTs that are often used to destroy saturated hydrocarbons in pump-and-treat groundwater remediation applications, the DMP technology requires less energy input, produces superior remediation performance, can operate in continuous mode for high throughput, ...
The joint effort will likely result in new beach closure thresholds and testing methods, and new recreational water quality criteria and testing methods for bacteria and viruses in State Water Quality Standards. These changes may require new disinfection practices for municipal waste water treatment facilities (e.g. advanced oxidation and UV) so are a particularly important consideration for facilities undergoing or about to embark on facilities planning efforts. Information on EPAs coliphage effort can be found HERE ...
The present study investigates the oxidation of methyl tert-butyl ether (MTBE) by conventional ozonation and the advanced oxidation process (AOP) ozone/hydrogen peroxide under drinking water treatment conditions. The major degradation products identified were tert-butyl formate (TBF), tert-butyl alcohol (TBA), 2-methoxy-2-methyl propionaldehyde (MMP), acetone (AC), methyl acetate (MA), hydroxyisobutyraldehyde (HiBA), and formaldehyde (FA). The rate constants of the reaction of ozone and OH radicals with MTBE were found to be 0.14 and 1.9 x 10(9) M-1 s(-1), respectively. The rate constants for the same oxidation processes were also measured fort he degradation products TBF, MMP, MA, and HiBA (k(O3-TBF) = 0.78 M-1 S-1; k(OH-TBF) = 7.0 x 10(8) M-1 s(-1); k(O3-MMP) = 5 M-1 s(-1); k(OH-MMP) = 3 x 10(9) M-1 s(-1), k(O3-MA) = 0.09 M-1 s(-1), k(O3- HiBA) = 5 M-1 s(-1); k(OH-HiBA) = 3 x 10(9) M-1 s(-1)). Since all compounds reacted slowly with molecular ozone only the degradation pathway of MTBE with OH ...
Atrazine is widely used as a selective triazine herbicide for controlling a wide varieties of broad-leaf and grassy weeds [1]. Atrazine herbicide is moderately present in the aquatic environment and has a low rate of biodegradability. Despite the atrazines low water solubility, there is much concern about the contamination of water resources with the highly toxic herbicides [2, 3]. Many studies reported that atrazines half-life in the aqueous phase and groundwater resources ranges from 41 to 237 days and 15 months to 20 years, respectively [4].. The maximum contaminant level for atrazine in drinking water established by the USEPA and WHO is 3.0 and 2.0 \( \mu \)gL−1, respectively [5]. Long-term effects of atrazine include probable human carcinogen, endocrine-disrupter, alteration in vitamins function, hepatotoxicity and renal toxicity [6].. Advanced oxidation processes (AOPs) [7] and photocatalytic oxidation process are efficient methods relying on hydroxyl radicals (OH°) production to ...
Estrogenic compounds are most significant endocrine disrupting compounds (EDC), which are of primary concern due to their widespread presence in the aqueous environment and also due to their adverse impact both on aquatic life and potential risk to human health. Conventional wastewater treatment plants are not designed to remove EDC, with biosorption on biosolids as the predominant removal mechanism. Anaerobic digestion is one of the most preferred processes employed for sludge stabilization in wastewater treatment plants. Advanced oxidation processes (AOPs) are seen as promising technologies for removal of estrogens from the environment. In this research, a controlled degradation study of estrogenic compounds in anaerobic digestion was undertaken. Anaerobic digestion of estrogens was not observed under any circumstances and pretreatment only played the role of reducing the estrogen loading on the anaerobic digesters. Digestion led to increase in estrogenicity which may be attributed to

There is a raise in concern as shown in recent studies, that when it comes to the traditional wastewater disinfection methods such as chlorination and ozonation, there is a formation of health related disinfection by-products such as trihalomethanes and haloacetic acids that can have carcinogenic tendencies. One of the alternative methods available for commercialization in the near future are advanced oxidation processes, which use semiconductor photochemistry in disinfection. The most effective photo catalyst for these disinfection purposes is TiO2, which is a non-toxic substance that is widely used in products like toothpastes and cosmetics. Traditionally these methods are added as a tertiary or final stage of wastewater treatment, which renders them an additional cost to wastewater systems. In this research, heterogeneous photo catalysis of TiO2 is combined with a pressure driven nanofiltration system, in order to integrate disinfection into a water quality solution and avoid the separation ...
ZnO and SnO2-doped ZnO nanoparticles were prepared by a sol-gel method for the first time. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the ZnO and SnO2-doped ZnO samples. Advanced oxidation processes (AOPs) have proved very effective in treatment of the various hazardous organic pollutants such as surfactants and pharmaceuticals in water. The photocatalytic degradation of drug phenylephrine hydrochloride (PHE) was studied as model organic pollutant. Under UV exposure the process was investigated with ZnO and SnO2-doped ZnO. The degradation was studied under different conditions including irradiation time, pH, catalyst concentration, phenylephrine hydrochloride concentration and potassium peroxydisulfate as an oxidant. The experimental results indicated that maximum degradation (99.4±1.0%) of drug occurred with SnO2-doped ZnO catalyst. The results demonstrated that photodegradation efficiency of SnO2-doped ZnO was significantly higher than that of undoped ZnO
