The corrosion inhibition of copper alloy was studied experimentally in our previous work. The effect of phenylenediamine (PDA), Tetraethylenepentamine (TEPA), Diethylenetriamine (DETA) and Ethylenediamine (EDA) were used and evaluated. Quantum chemical and theoretical calculations were carried out in present study. Several quantum parameters are obtained via two computer software. Maximum energy band gab was 6.263 eV for PDA, while minimum one was 3.057 eV in the case of EDA, which support the experimental results of inhibitors efficiency. A comparative study was done. Theoretical calculations are a powerful way for estimation inhibitors efficiencies. A good correlation was seen between experimental inhibitor efficiency and theoretical one with high correlation coefficients. © 2017, University of Mohammed Premier Oujda Morocco.


Objectives: To determine the role of Bcl2 and p53 gene expression in the pathogenesis of antral-predominant non-atrophic gastritis (APNG) according to Helicobacter pylori (HP) cytotoxin-associated gene A (CagA) status. Methods: Multiple antral biopsies were taken from 78 patients for rapid urease test, histopathology, Bcl2 and P53 immunohistochemistry and HP CagA in situ hybridization. Results: CagA was detected in 74.35% cases. There was no significant difference in Bcl2 expression among CagA+ and CagA− APNG cases. Significant differences in polymorphonuclear neutrophils (PMNs) and lymphocytes grades were detected among CagA+ and CagA− APNG cases. There was no significant correlation among patients’ age, inflammatory infiltrates, Bcl2, p53 expression. CagA has positive correlation with p53 (p=0.001), PMNs grade (p=0.027), lymphocytes grade (p=0.003), inflammation intensity (p=0.006), and inflammation activity (p=0.007). Bcl2 has no significant correlation with p53, CagA, PMNs, and lymphocytes indexes. P53 expression has significant correlation with PMNs and lymphocyte grades (p=0.000), inflammation intensity (p=0.003), and inflammation activity (p=0.002). PMNs grade has positive correlation with lymphocyte grade, inflammation intensity, and activity (p=0.000). Lymphocyte grade has a significant correlation with inflammation intensity and activity (p=0.000). Inflammation intensity has a significant correlation with inflammation activity (p=0.000). Conclusions: CagA cytotoxin has direct effect on P53 gene and indirect effect on Bcl2 gene expression in APNG cases. Bcl2 and P53 expression do not get affected by patient’s age and gender. PMNs grade, lymphocytes grade, inflammation intensity, and inflammation activity affected directly by P53 and CagA cytotoxin expression and indirectly by Bcl2 expression. The balance of P53-Bcl2 pathways play a vital role in pathogenesis of HP and CagA-induced APNG. © 2017 The Authors.

This research was conducted to study potassium status and forms in some desert Torrifluvents soil, from south of Libya and to clarify the effect of cultivation on its forms. Composite soil samples were collected from surface soils (0-30 cm) of some cultivated fields and from larva regions besides these fields. Various forms of potassium were determined i.e. soluble-K, NH4OAC extractable-K, reserve-K, sulphuric acid-K, boiling nitric acid-K to determine primary step-K and total step-K, and total K. Results indicated that all soils have high content of soluble and exchangeable potassium, and within the range of arid and semi-arid soils. Reserve-K was ranged between 0.359- 3.422 cmol kg-1 with an average of 1.702 and 2.637 cmol kg-1 in cultivated and virgin soils respectively. All soils had low content of primary step which ranged between 0.214-1.294 cmol kg-1 with an average of 0.522 and 0.926 cmol kg-1 in cultivated and virgin soils respectively. Total step potassium was ranged between 0.982-5.995 cmol kg-1 with average of 2.480 and 3.765 cmol kg-1 for cultivated and larva soils respectively. Total potassium concentration was between 15.16-36.71 and 23.53-30.06 cmol kg-1 with average of 24.52 and 26.38 in cultivated and virgin soils respectively. All forms of potassium were decreased as a result of cultivation. Apart from K-HCl and total K, the rest forms of potassium were significantly correlated with each other's.

This work was conducted to assess the impact of soil salinization and sodification on natural vegetation and land deterioration in Wadi Al-Shatti, Southern Libya. Fallow soils were very strongly saline with mean ECe of 111.2 and 68.78 dS m-1 in crust and surface layers respectively. The cultivated soils were moderately, strongly and very strongly saline with mean ECe of 14.52 dS m-1. Sodium was the dominant cations, followed by calcium and magnesium. Chloride was the dominant anion. Very low concentrations of bicarbonate and absence of carbonate was recorded. Sodium chloride was prevalent salt in all samples, followed by calcium sulphate in some and magnesium chloride in the others. Sodium and magnesium sulphate were found in some samples, while the presence of calcium and magnesium chloride was confined in fallow soils and crust of very high salinity. Crust and surface layers of fallow soils have high values of ESP with means of 47.78 and 33.85% respectively, whereas low values were noticed in cultivated soils with mean of 18.10%. Field study results showed the disappearance of ordinary natural vegetation and the occurrence of halophyte plants, like; Athel trees (Tamarix aphylla), Spiny rush (Juncus acutus), Cogon grass (Emperica cylinderica), Camel thorn (Alhagi maurorum) and Nitre bush (Nitraria retusa). Degradation indices confirmed that the cultivated soils suffered from slight to moderate deterioration, whereas fallow soils suffer from sever to very sever deterioration.

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.

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.

Two methods were experimented to regenerate the spent ZnO catalyst. The first one involved combustion by air while the second one involved steam treating of catalyst. The results abstracted from the first method showed that it is not suitable and reliable in regeneration of the catalyst because of the formation of zinc sulphate which cause blockage of the catalyst pores and hence reduce its activity. The steam regeneration method seem to be very practical and promising as the catalyst regenerated have a good activity which approached 97 %, in addition, the physical and chemical properties of the regenerated catalysts was very close and similar to the commercial new one © EuroJournals Publishing, Inc. 2010.
