Research Journal of Poultry Sciences , 2012,
Abstract: This experiment was carried out to evaluation usage different levels of Canola Oil (CO) (0, 2 and 4%) and Choline Chloride Supplement (CCS) (0, 500 and 1000 mg kg 1) in the basal diet (corn and soybean meal) and their effects on the broiler chick s performance. This trial was conducted in 3 3 factorial experiment with Completely Randomized Design (CRD) with 270 male chicks (Ross 308). All diets were isoenergetic and isonitrogenous and balanced with NRC recommendation. Result shown that interaction effects of canola oil and choline chloride supplement could affected Live Body Weight (LBW), Feed Intake (FI) and Feed Conversion Ratio (FCR). In 22-42 day old canola oil and choline chloride supplement in 9 and 6 treatment (T9 = 4% canola oil + 1000 mg kg 1 choline chloride supplement and T6 = 2% canola oil + 1000 mg kg 1 choline chloride supplement) could significantly increase the live body weight, respectively (p<0.0001) and canola oil and choline chloride supplement in 8, 7 and 6 treatment (T8 = 4% canola oil + 500 mg kg 1 choline chloride supplement, T7 = 4% canola oil + without choline chloride supplement and T6 = 2% canola oil + 1000 mg kg 1 choline chloride supplement) could significantly increase the feed intake respectively (p<0.0001) and in 9 and 8 treatment (T9 = 4% canola oil + 1000 mg kg 1 choline chloride supplement and T8 = 4% canola oil + 500 mg kg 1 choline chloride supplement) could significantly decrease the feed conversion ratio respectively (p<0.0001). In 43-56 day old canola oil and choline chloride supplement in 6 and 4 treatment (T6 = 2% canola oil + 1000 mg kg 1 choline chloride supplement and T4 = 2% canola oil + without choline chloride supplement) could significantly increase the live body weight (p<0.0001) and canola oil and choline chloride supplement in 1, 2, 4 and 7 treatment (T1 = basal diet, T2 = without canola oil + 500 mg kg 1 choline chloride supplement, T4 = 2% canola oil + without choline chloride supplement and T7 = 4% canola oil + without choline chloride supplement) could significantly increase the feed intake respectively (p<0.0001) and in 9 and 8 treatment (T9 = 4% canola oil + 1000 mg kg 1 choline chloride supplement and T8 = 4% canola oil + 500 mg kg 1 choline chloride supplement) could significantly decrease the feed conversion ratio respectively (p<0.0001). No mortality was in all over period.

Indian Journal of Medical Sciences , 2009,
Abstract: Background: Vancomycin-resistant enterococci pose an emerging health risk. The limitation in therapeutic options has resulted in the development of new drugs such as quinupristin/ dalfopristin and linezolid. Aim, Setting and Design: This study investigated the species prevalence and antibacterial resistance among enterococci isolated in selected Tehran hospitals. Materials and Methods: Between March 2006 and August 2007, 200 enterococcal isolates from urine, blood, stool and wound were recovered in 2 teaching hospitals of Tehran province. Susceptibility of all isolates was tested against vancomycin, teicoplanin and linezolid antibiotics by disk diffusion and agar dilution method. Results and Conclusion: Seventeen (8.5%), 6 (3%) and 4 (2%) of the isolates were resistant to vancomycin, teicoplanin and linezolid, respectively. Within the vancomycin-resistant isolates, 6 (35.2%), 4 (25%) and 1 (5.88%) showed vanA, vanB and vanC genotype patterns, respectively. Four (23.5%) of VRE isolates were resistant to linezolid with minimum inhibitory concentrations between 16 and 32 μg/mL. Two linezolid vancomycin resistant enterococci were E. faecium.

Journal of Biological Sciences , 2008,
Abstract: The aim of this study was to evaluate the risk of legionellosis within the hospital water supplies. Legionella species are ubiquitous in various water systems. It is not surprising that hospital waters may be colonized with legionnaire bacterium. Cold and hot water samples from different hospitals of Tehran were screened, using standard culture method and PCR technique. A total of 132 cold and hot water samples were collected during the summer of 2006. All samples were concentrated and cultured on standard BCYE agar after pretreatment. The mip gene based primer system were then used to detect mip protein of L. pneumophila within each hospital water sample. The results were obtained from culturing and PCR compared to each other. The water samples that analyzed in this study were collected from hospitals and medical institution located in different parts of the city. Legionella were isolated from the total of 30 water samples (22.7%). The mip based primer sets by amplicon size of 630 bp detected Legionella genome from approximately (37%) of the culture positive samples that indicating they could be considered as L. pneumophila. The results showed that the risk of nosocomial legionellosis could not be excluded from the city hospitals due to significant contamination of the hospital water supplies. We concluded that hospital water screening for Legionella pneumophila contamination will help the diagnosis the threat of nosocomial outbreak of legionnaires` disease and also the evaluation of decontamination process of water supplies within high risk areas.

Abstract: Unwanted water production together with oil and gas production is a striking problem in oil and gas industries, and many approaches have been examined to overcome this major problem. Preformed particle gels (PPGs) showed dramatically good properties for this purpose in mature oil and gas reservoirs. In this study, we carefully synthesized an efficient series of PPGs with using a design of experiments (DOE) software. Acrylamide (AAm)/Acrylic acid (AA) mole ratio, N,N’-methylenebisacrylamide (MBA) mole percentage and swelling time were considered as key parameters to examine PPG swelling behavior. Our results presented a detailed empirical correlation, which could significantly predict the swelling capacity of PPGs in CaCl2 salt solution (200,000 ppm).

Journal of Animal and Veterinary Advances , 2012,
Abstract: One of the most famous omega 3 fatty acids source is canola oil. The aim of this study was to evaluate the effects on omega 3 fatty acids include of Docosahexaenoic (DHA) and Eicosapentaenoic (EPA) content when Canola Oil (CO) was included in broiler chicks rations. Ninety one day old male broiler chicks (Ross- 308) were randomly distributed into 3 treatment: Control (0% CO), 2% CO and 4% CO for 5 week. These diets were isonitrogenous and isoenergetic were given to broiler chickens throughout a 42 days growth period. Eicosapentaenoic and docosahexaenoic acids and other fatty acids were analyzed by gas chromatography. This trial was conducted in completely randomized design. Birds were slaughtered at 56 days of age. Breast and thigh meat samples were separated and frozen at -20 C until to determine as fatty acid profile. Data was analyzed with one way ANOVA and means compared with Duncan test. Results show that using CO with high level of omega 3 fatty acids could influence fatty acid profile and improved meat quality. With increasing dietary canola oil level in diet (from 0-4 g kg 1 diet) omega 3 contents that were significantly (p< 0.05) increased in thigh and breast meat. N-3 fatty acids, DHA and EPA content were significant among treatment (p< 0.05).
