an extensive study of fischer-tropsch synthesis (fts) on alumina-supported cobalt catalysts promoted with different amounts of ruthenium and rhenium is reported. up to 2 wt% of promoters, are added to the catalyst by coimpregnation. the catalysts are characterized by different methods including: bet physisorption, x-ray diffraction, hydrogen chemisorption, and temperature-programmed reduction. ...
background and objectives: zinc oxide (zno) nano-particles have been proven to have strong antibacterial activity against food borne pathogens. the practical applications of different concentrations (control, 0, 1, 2, 4, 6 and 8 mm) of zno suspensions containing 1% acetic acid were investigated against the pathogenic bacteria like staphylococcus aureus. materials and methods: the projects of la...
چکیده : مقدمه : ابتلا به آترواسکلروز در بیماران دیابتی بیشتر از افراد سالم می باشد . هموسیستئین می تواند به عنوان یکی از عوامل خطرزای آترواسکلروز مطرح با شد . آنزیم لستین کلسترول آسیل ترنسفراز نقش مهمی را در پاک سازی کلسترول آزاد در بافت ها از طریق عملکرد hdl-c بر عهده دارد .هدف از این مطالعه تعیین سطح فعالیت لستین کلسترول آسیل ترنسفراز (lcat activity ) در بیماران دیابتی نوع 2 در مقایسه با افر...
heteropoly acid promoted nanoparticle of nickel oxide samples were prepared by sol-gel method using heteropoly acids. prepared composite was characterized by xrd, ft-ir and icp technique. in this work, we have reported bromination of phenol, its derivatives and some aromatic compounds. the liquid phase bromination of phenol was performed using heteropoly acids immobilized nanoparticle of nickel...
Background and objectives: A key aspect of cisplatin-induced hepatotoxicity is oxidative stress. The current study was conducted to show, for the first time, the restoring and synergistic effects of morin and hesperidin against oxidative stress in hepatotoxicity. Methods: Fourty-two Wistar albino rats were randomly divided into seven groups: group A (control), ...
Abstract Background and Objective: Recently, diabetes mellitus has been known as one of the main cause of upper gastrointestinal symptoms. Since a high prevalence of H. Pylori in diabetic patients has been reported, we aimed to evaluate the level of gastric juice Nitric Oxide (NO°), Oxidative Stress and Glycated Hemoglobin. Material and Methods: In case group, the participants were 60 diabe...
Background: Physical activity has a range of effects on male reproductive function depending upon the intensity and duration of the activity. Materials and Methods: In order to investigate the protective effects of nano zinc oxide on endurance exercise induced testicular oxidative stress, 30 adult male Wistar rats were randomly divided into the following groups: control group (n=10); exercised ...
Background: Studies have shown that metal nanoparticles are highly active and exhibits remarkable bactericidal activity against a wide range of bacteria. Objective: The aim of this study was to examine the antibacterial activity of zinc oxide nanoparticles against standard strains of Pseudomonas aeruginosa and Staphylococcus aureus and their isolates in food products. Methods: This experiment...
a hydroponics study was carried out in order to understand the behavior of antioxidant enzymes, soluble protein content and its effect on cell death in different old leaves of durum wheat. two month after planting, the different old leaves were sampled and the activity of super oxide dismutase (sod), catalase, ascorbat peroxidase and guaiacol peroxidase were measured. furthermore, the rate of c...
The gaseous neurotransmitter nitric oxide plays an important role in the modulation of corticostriatal synaptic transmission. This study examined the impact of frontal cortex stimulation on striatal nitric oxide efflux and neuron activity in urethane-anesthetized rats using amperometric microsensor and single-unit extracellular recordings, respectively. Systemic administration of the neuronal n...
