Patients with chronic inflammatory disorders (ID) have an increased risk of developing cardiovascular disease, and routinely determined parameters do not reveal the real metabolic status of specific subgroups, such as patients with rheumatoid arthritis (RA). In this study, in order to evaluate state of the art markers for the assessment of cardiometabolic risk, abnormalities in lipoprotein leve...

nitrate is one of the pollutants of groundwater and the great amount of nitrate in drinking water can bring about some hygienic problems such as methemoglobinema phenomena in children. therefore, this research aims to study the efficiency of photo- fenton in removing nitrate and investigating the variables affecting it in aqueous solutions. this research was carried out in water and wastewater ...

Novel advanced oxidation processes (AOPs) show great promise for application in many wastewater treatment areas. AOPs are an emerging technology that may be employed for specific goals in wastewater treatment. These AOPs utilize the very strong oxidizing power of hydroxyl radicals to oxidize organic compounds to the preferred end products of carbon dioxide and water. Advanced oxidation has been...

During recent years, many advanced oxidation techniques have been investigated for water and wastewater treatment to overcome the shortage of clean water. This review summarizes the background and principles of photocatalysis applied as an advanced oxidation technology. In particular, this paper focuses on modification of photocatalysts with various dopants as well as the novel photocatalytic r...

In two recent studies, Wu et al. showed that fasting plasma levels of fluorescent oxidation products are markers of oxidative stress (1) and independently predict coronary heart disease in men (2). The authors concluded that this fluorescent assay may become a useful global marker for epidemiologic studies. As mentioned by Wu et al., ‘‘this method has not been widely used [as it may be] a nonsp...

Potentially harmful disinfection byproducts (DBPs), as a significant challenge in water treatment, are formed when oxidizing disinfectants react with natural organic matters (NOM). Unfortunately, an  unwanted  side  effect  is  the  formation  of  harmful by-products,  such  as  THMs  and  HAAs, following the chlorination stage. DBPs  cause a variety of diseases like cancer in humans.  In this ...

This study presents a review on advanced oxidation processes (AOP) for simultaneous removal of NO and SO2. AOP is based on using a strong oxidant such as ozone and H2O2 which is able to generate highly reactive intermediates. The pollutant will be oxidized and removed by these intermediates. In recent years, AOP has been considered as an effective and attractive technology in the field of flue ...

Many industrial activities utilize organic compounds as a key chemical in organic synthesis of special chemicals such as, synthetic resins, paper products, medicinal products, drugs, dying and others. Different chemical processes, most of them based in oxidation-reduction reactions, are being applied. Processes such as chlorination, ozonation, UV irradiation, electrochemical treatments and proc...
