    166-173In this study, colour and chemical oxygen demand (COD) removal from the textile wastewater by heterogeneous Fenton process have been investigated. Primarily, the Fe(III)/SnO2 catalyst is prepared by co-precipitation method and characterized by BET analyses. The BET analysis results show that the pore size of the Fe(III)/SnO2 catalyst is 2.013 nm and it is classified as a mesoporous catalyst. Then the prepared catalyst is used in the heterogeneous Fenton tests. The effects of the amount of the catalyst, pH of the solution, hydrogen peroxide (H2O2) concentration, temperature and reaction time on the color and COD removals have been studied and the optimum conditions are determined. In the optimum experimental conditions (2.0 g/L of 8 wt.% Fe/SnO2, pH 2, hydrogen peroxide concentration 300 mg/L, temperature 35C and reaction time 90 min), 91% colour and 86% COD removal efficiencies are obtained. The COD removal kinetics of textile wastewater is also investigated. It is determined that the removal of COD obeyed the second-order kinetics. Finally, stability and reuse of the catalyst are tested. This catalyst can be successfully used repeatedly and suitable for textile wastewater treatmen

    With the increase in industrialization, the unconscious use of surface and groundwater has led to the rapid pollution of water, which is the main source of life for all living things. As a result, the need for clean water has brought the global water crisis to the agenda. The textile industry is one of the largest producers of wastewater in the world. Textile industry wastewater contains high amounts of non-biodegradable organic compounds, high concentrations of dyestuffs, salt, detergent and soap. Therefore, it is of great importance to remove organic pollutants in this wastewater. Since traditional methods are insufficient to remove organic compounds in wastewater, advanced treatment methods are required. Advanced oxidation processes (AOPs) are one of the alternative treatment methods preferred in recent years. In this study, color removal from textile industry wastewater was researched by the heterogeneous Fenton process, which is an advanced oxidation process. The parameters such as catalyst dosage, pH, hydrogen peroxide concentration, temperature, reaction time and mixing speed that effect heterogeneous Fenton processes were investigated. Under optimum experimental conditions, the color removal efficiency was achieved as 84.4%

    Symmetric bisthiocarbohydrazone compounds (1, 2, 3) were obtained by the condensation of thiocarbohydrazide with carbonyl compounds such as isatin (a heterocyclic ketone) and two hydroxyl aldehydes (2-hydroxybenzaldehyde, 2-hydroxy-1-naphthaldehyde) respectively, according to the previously reported methods. These synthesized compounds were evaluated in terms of their anti-tyrosinase, anti-elastase and antioxidant potentials in vitro. All of the tested compounds exhibited anti-tyrosinase and anti-elastase activities. It was observed that the inhibition increased with the increase of bisthiocarbohydrazone concentrations. Compound 1 showed the highest anti-tyrosinase activity. The anti-tyrosinase activity is decreasing in the following order; 2<3<1. Compound 1 showed also the highest anti-elastase activity. The anti-elastase activity is decreasing as 3<2<1. As a result, the most effective compound in terms of anti-tyrosinase and anti-elastase activities is bisthiocarbohydrazone derived from isatin. Compounds 2 and 3 with the hydroxyl substitution showed antioxidant activity close to Trolox. These compounds were found to have significant reducing effects and to be effective scavengers of DPPH

    AbstractPhysical activity level (PAL) is an important factor to promote and maintain a healthy lifestyle along the whole life cycle. The children and adolescent period is the critical time to acquire positive lifestyle habits. The purpose of this study was to investigate the effect of both high school entrance exam (HSEE) and parental behaviors on habitual PAL of students during the preparation of this exam. Totally 319 Elementary School students (154 girls, 165 boys) between ages of 11-13 were selected randomly for this study. PAL of students were evaluated by using the Beacke Physical Activity Questionnaires. There were a no significant differences between attendance and non attendance to extra courses for HSEE in terms of word activity (WA), sport activity (SA), and leisure activity (LA) scores (p<.05) among the students. It was shown that regular physical activity attendance of mothers plaid a significant role in LA scores (p≤.03) among the students. However, WA, and SA scores of students were not affected from their mother's habitual activities (p<.05). On the other hand, there were significant differences in WA, and SA according to father's regular physical activity attendance (p≤.01).As a conclusion, parental habitual physical activity level played an important role in high score of student's LA. It is recommended to monitor and promote parental physical activity

    IntroductionElevated transaminases and/or creatine phosphokinase can indicate underlying muscle disease. Therefore, this study aims to determine the frequency of Duchenne muscular dystrophy/Becker muscular dystrophy (DMD/BMD) in male children and Pompe disease (PD) in male and female children with isolated hypertransaminasemia.MethodsThis multi-center, prospective study enrolled patients aged 3–216 months with serum alanine transaminase (ALT) and/or aspartate transaminase (AST) levels &gt;2× the upper limit of normal (ULN) for ≥3 months. Patients with a known history of liver or muscle disease or physical examination findings suggestive of liver disease were excluded. Patients were screened for creatinine phosphokinase (CPK) levels, and molecular genetic tests for DMD/BMD in male patients and enzyme analysis for PD in male and female patients with elevated CPK levels were performed. Genetic analyses confirmed PD. Demographic, clinical, and laboratory characteristics of the patients were analyzed.ResultsOverall, 589 patients [66.8% male, mean age of 63.4 months (standard deviation: 60.5)] were included. In total, 251 patients (188 male and 63 female) had CPK levels above the ULN. Of the patients assessed, 47% (85/182) of male patients were diagnosed with DMD/BMD and 1% (3/228) of male and female patients were diagnosed with PD. The median ALT, AST, and CPK levels were statistically significantly higher, and the questioned neurological symptoms and previously unnoticed examination findings were more common in DMD/BMD patients than those without DMD/BMD or PD (p &lt; 0.001).DiscussionQuestioning neurological symptoms, conducting a complete physical examination, and testing for CPK levels in patients with isolated hypertransaminasemia will prevent costly and time-consuming investigations for liver diseases and will lead to the diagnosis of occult neuromuscular diseases.

    A new symmetric bisthiocarbohydrazone [1,5-bis(5-allyl-2-hydroxy-3-methoxybenzylidene)thiocarbohydrazone (H2L)] was prepared from the reaction of thiocarbohydrazide with 5-allyl-2-hydroxy-3-methoxybenzaldehyde. Five new solvate dioxomolybdenum(VI) complexes of close formulas [MoO2(L)R-OH] (R: methyl for Mo1, ethyl for Mo2, propyl for Mo3, butyl for Mo4 and pentyl for Mo5) were synthesized by reacting bis(acetyla-cetonato)dioxomolybdenum(VI) [MoO2(acac)2] with this proligand H2L. The structures of all compounds were verified by IR, UV-vis and 1H NMR spectroscopies, elemental analysis, magnetism and molar conductivity measurings. The solid-state structures of Mo1 and Mo2 were also elucidated using the X-ray crystallography technique. X-ray crystallographic studies indicated that symmetric bisthiocarbohydrazone is coordinated to the cis-MoO22+ ion through sulfur atom, imine nitrogen and phenolic oxygen as the tridentate ONS donor. The sixth coordination of the molybdenum atom, which has distorted octahedral geometry around it, is completed by solvent (R-OH). The thermal characteristics of the compounds were studied by thermogravimetric analysis (TGA). TGA results support the presence of solvent molecules coordinated to molybdenum atoms in the com-plexes. Antioxidant capacities of the compounds were measured using the CUPric Reducing Antioxidant Capacity (CUPRAC) method. The compounds were also examined for their free radical scavenging activities by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical method. When compared to a standard, Trolox, all of the com-pounds demonstrated good antioxidant activity
