Background and purpose: Dyes are one of the major sources of chemicals responsible for environmental pollution. Synthetic dyes degradation in industrial wastewaters has received increasing attention due to their high solubility and stability in water. In the present study, the photocatalytic efficiency of as-synthesized nano- TiO2 supported on the H-form Fe- Fe-ZSM-5 zeolite was investigate...
Abstract This article is a part of scientific project focused on obtaining new type composite materials that are characterized by singlet oxygen generation upon irradiation with red light, which can be used as antibacterial agents. The material nanoscale graphite oxide (GO) particles covalently bonded to an axially substituted zirconium phthalocyanine complex. For this purpose, two complexes, m...
The umu test system is a newly developed method to evaluate genotoxicities of a wide variety of environmental carcinogens and mutagens (Oda et al., 1985; Nakamura et al., 1987). In the present study, SOS-inducing activity of 142 synthetic dyes was investigated by the umu test using Salmonella typhimurium (TA1535/pSK1002) under the condition of absence and presence of rat liver microsomal fracti...
background: although red meat consumption is related to the prevalence of diabetes, few data are available showing the relationship between red meat intake, inflammation, and metabolic syndrome. the study aimed to identify the association between the red meat intake, metabolic syndrome, and circulating concentration of c-reactive protein (crp) as a surrogate measure of inflammation. methods: in...
INTRODUCTION Red blood cell transfusions are common in intensive care units. For many years, transfusions of red blood were thought to have obvious clinical benefits. However, in recent years, the risks and benefits of blood transfusions have been examined more carefully, including the risk of increased morbidity and mortality due to transfusion-related immunomodulation effects. OBJECTIVES To...
Automatic Code Generation for Red-Time Reactive Systems in TROMLAB Environment
objective(s) sickle cell disease is a genetic disorder characterized by chronic haemolytic anaemia. haemoglobin s containing red blood cells may be susceptible to oxidative stress due to imbalance between production of reactive oxygen species and the countering effect of the various antioxidants present in the body. materials and methods we evaluated some antioxidant enzymes which include gluta...
استفاده از پارچههای بافته شده از مخلوط الیاف طبیعی و مصنوعی به منظور بهرهمند شدن از خواص مطلوب هر یک از اجزاء، متداول میباشد. روش شناخته شده برای رنگرزی این نوع کالاها، استفاده از مواد رنگزای راکتیو/ دیسپرس و یا مخلوط آنهاست که برای رنگرزی جزء پنبهای با رنگزای راکتیو از قلیا استفاده میشود. از آنجایی که افزودن قلیا سبب بروز مشکلاتی از جمله ایجاد نایکنواختی در رنگرزی شده و از طرفی زمانبر اس...
Synthetic dyes are using extensively in various industries such as textile, leather tanning, plastic, pulp and paper. Since this dyes are mainly toxic and even carcinogenic, discharging dye containing wastewater into the environment generates serious environmental and health consequences. Therefore, in this research investigated and evaluated the removal effect of Reactive Red 120 (RR 120) from...
toxicity, cancinogenic activity, and mutagenicity. The purpose of this study was evaluation of the removal of Reactive Red 120 (RR-120) dye from aqueous solution by date Palm (Phoenix dactylifera) seed particles. Batch adsorption studies carried out to study various parameters included contact time, initial concentration of Reactive Red 120, pH, and adsorbent dosage. The concentration of dye wa...
