Our research focused on the production, characterization and application of silver nanoparticles (AgNPs), which can be utilized in biomedical research and environmental cleaning applications. We used an environmentally friendly extracellular biosynthetic technique for the production of the AgNPs. The reducing agents used to produce the nanoparticles were from aqueous extracts made from the leav...
We examined the effect of lactational exposure to tributyltin on innate immunodefenses in the F1 generation using in vivo and in vitro experiments. Pregnant C57BL/6 mice were given drinking water containing 0, 15, or 50 microg/ml of tributyltin chloride (TBTCl) from parturition to weaning. At weaning time, offspring were inoculated with Escherichia coli K-12, and bacterial clearances from the p...
Paints with high lead concentrations (ppm) continue to be sold around the world in many developing countries and those with economies in transition representing a major preventable environmental health hazard that is being increased as the economies expand and paint consumption is increasing. Prior lead paint testing had been performed in Brazil and India and these countries were selected to ex...
The effects of antibiotic, probiotic, and prebiotic as dietary feed additives on carcass composition as well as Salmonella counts and its serotypes in droppings and intestine of broiler chickens on days 1, 28, and 56 of experiment were investigated. Dietary treatments were control diet (basal diet without additives), OXYT diet (basal diet with 600 ppm of the antibiotic oxytetracycline), GRO-UP ...
Chemical Composition, Antioxidant, and Antibacterial Activity of Wood Vinegar from Litchi chinensis.
The antioxidant and antibacterial activities of wood vinegar from Litchi chinensis, and its components have been studied. The chemical compositions of wood vinegar were analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 17 chemical compounds were identified, representing 83.96% of the compositions in the wood vinegar. Three major components, included 2,6-dimethoxyphenol (syrin...
Preclinical and clinical studies have provided evidence that aspirin, celecoxib, (cyclooxygenase-2 inhibitor), and statins (3-hydroxy-3-methylglutaryl CoA reductase inhibitors) inhibit colon carcinogenesis. Chronic use of high doses of these agents may induce side effects in ostensibly normal individuals. Combining low doses of agents may be an effective way to increase their efficacy and minim...
To investigate the efficacy of alternatives to antibiotics, the present study was conducted to compare the effects of antibiotic, lactic acid, a blend of commercial essential oils (EOs) and EOs in combination with lactic acid on growth performance and the functional activity of the gut in broiler chickens. A total of 168 broiler chickens were given the basal diet supplemented with 10 ppm colist...
مقدمه: فلاونوییدها طبقه بزرگی از پلی فنل ها با بیش از 4000 ترکیب هستند، اغلب مسؤول رنگ زرد، قرمز و ارغوانی گل ها، میوه ها و سبزیجات در گیاه هستند . فلاونوییدها نقش آنتی اکسیدانی را در فتوسنتز گیاهان به عهده دارند ، فلاونوییدها دارای اثرات آنتی اکسیدانی، ضد التهابی، جلوگیری کننده سرطان و محافظت کننده از قلب می باشند. هدف : هدف از این تحقیق، استخراج و اندازه گیری ترکیب های فلاونوییدی کامفرول و کو...
