This study was conducted to examine the effects of Zingiber officinale (ginger) powder on male broiler reproductive system. Zingiber officinale was administered in the feed of two groups of male broiler breeder (30 wk age) at levels of 5 and 10 kg/ton, Third group was a control group (no additive). Treatments were ejaculate volume, sperm concentration, counts, movements, motility and abnormality, blood serum LH, FSH and testosterone concentration. The ginger caused a significant increase (p<0.05) in ejaculate volume, sperm concentration, counts, movements and a significant decrease (p<0.05) in motility and abnormality. There was also a significant increase (p<0.05) in blood serum LH, FSH and testosterone levels. Our results indicated that Zingiber officinale powder possesses pro-fertility properties in male broiler which might be a product of androgenic activities. © Asian Network for Scientific Information, 2011.

This paper reports the results of mass loss measurements in the corrosion inhibition of mild steel in different concentrations of H3PO4 in the temperature range 30-60 °C using potassium iodide as an inhibitor. The present work is focused on determining the optimum mathematical equation and the ANN architecture in order to gain good prediction properties. Three mathematical equations and three ANN architectures are suggested. Computer aided program was used for developing these models. The results show that the polynomial mathematical equation and multi-layer perception are able to accurately predict the measured data with high correlation coefficients. © 2013 Korean Institute of Chemical Engineers, Seoul, Korea.

The effect of different temperatures and acid concentrations on the corrosion of mild steel in nitric acid are addressed in this work. The effect of temperature is explained by the application of the Arrhenius equation and transition state theory, while the acid concentration effect is explained using reaction kinetic equations. The combined effect of temperature and acid concentration is then modeled using a nonlinear regression method. Thermodynamic parameters of activation (E, ΔH* and ΔS*) and detailed kinetic studies for the corrosion reaction are carried out. Nonlinear corrosion rates as a function of temperature and acid concentration are estimated with a good prediction of corrosion rate values. The values of activation energy E and enthalpy of activation DH., decrease with an increase in acid concentration indicating the increasing reaction rate. Entropies of activation DS.tend to lower values with increasing acid concentration, which indicates that the activated complex is more orderly relative to the initial state. The corrosion reaction was approximately first order. © Akadémiai Kiadó, Budapest, Hungary 2014.

AIM: To determine the risk factors associated with H. pylori infection and possible correlation with clinicopathological parameters. MATERIAL AND METHODS: Gastroduodenal biopsies were examined by rapid urease test and Gram staining. Cag A cytotoxin was detected by in situ hybridization. RESULTS: Risk of H. pylori acquisition reported as following: Males have 1.38 fold, rural residents have 0.63 fold, Nonsmokers have 0.39 fold, mild smokers have 18 fold, and moderate smokers have 1.4 fold while heavy smokers have 1 fold. A person who’s in contact with animals has 1.52 fold risks. Illiterates and patients with primary education have 5.36 & 3 fold risk respectively. Pa-tients under proton pump inhibitor (PPI) therapy have 1.02 fold. Patients under NSAID therapy have 3.48 fold while nonalcoholic Patients have 0.75 fold. Patients using tap water have 0.45 fold risk. H. pylori infection positively correlated with age, weight loss, and heartburn. H. pylori inversely correlated with endoscopic diagnosis, Cag A positivity, and education level. Cag A positivity corre-lated with animal contact and NSAID usage. CONCLUSIONS: Several life style factors, education, animal contact, using of PPI, and NSAIDs increase the risk of H. pylori infection. Weight loss and heartburn cardinal signs for H. pylori infec-tion. Endoscopic diagnosis and clinicopathological parameters not strictly associated with Cag A positivity. © 2015 Ali Ibrahim Ali AL-Ezzy.

The purpose of this study was to evaluate the ability of clindamycin and metronidazole to synergize with natural antimicrobials against biofilms of bacterial vaginosis (BV)-associated Gardnerella vaginalis. Minimum bactericidal concentrations for biofilm cells (MBCs-B) were determined for each antimicrobial. The MBCs-B of lauramide arginine ethyl ester (LAE), subtilosin, clindamycin and metronidazole were 50, 69.5, 20 and 500 μg mL(-1), respectively. A checkerboard assay and isobologram were used to analyze the type of interactions between these antimicrobials. The combination of metronidazole with natural antimicrobials did not inhibit planktonic lactobacilli. Clindamycin with either LAE or with subtilosin was inhibitory for planktonic but not for biofilm-associated lactobacilli. All tested antimicrobial combinations were inhibitory for BV-associated Mobiluncus curtisii and Peptostreptococcus anaerobius. LAE and subtilosin synergized with clindamycin and metronidazole against biofilms of G. vaginalis but not biofilm-associated vaginal lactobacilli. The biofilms of BV-associated pathogens can be controlled by synergistically acting combinations of conventional antibiotics and natural antimicrobials which will help better management of current antibiotics, especially considering robust bacterial resistance. Our findings create a foundation for a new strategy in the effective control of vaginal infections. © FEMS 2015. All rights reserved. For permissions, please e-mail: email@example.com.
