Background and objective :Helicobacter pylori [H.pylori] infection is one of the most common chronic bacterial infections worldwide especially in the developing countries. This bacterium is the cause of many diseases such as MALT lymphoma, gastritis, peptic ulcers, and stomach cancer. According to recent reports, H.pylori infection may increase the risk of colorectal cancer. The current study aimed at investigating the association of H. pylori infection and the risk of colorectal cancer and adenomatous polyps. Methods: The current study was conducted on 52 patients with colon cancer as the case group and 200 subjects without pathological finding (i e, polyps, neoplasms, or inflammatory diseases) as the control group. Blood samples were collected from the patients in order to assess the presence of anti-H. pylori infection antibodies by the serum titer levels of anti-H. pylori IgG antibodies were measured using enzyme-linked immunosorbent assay (ELISA) with commercial kit by (Dia.Pro Diagnostic Bioprobes-Italy). Results: This study demonstrates distinct associations between H.pylori infection markers and CRC risk. While IgG seropositivity showed a significant 2.16-fold increased CRC risk (p = 0.019). Conclusion: This research finding IgG seropositivity may serve as a broader risk marker.

Abstract: 

This study presents a critical discourse analysis (CDA) of the construction of political identity 

during periods of revolutionary crisis. It examines the dichotomous representation of Muammar 

Gaddafi in February 2011 through two primary data streams: his first major public address 

following the uprising (February 22, 2011) and the contemporaneous visual and textual 

coverage in three newspapers—The Sun (UK), The Daily News (a prominent US tabloid-style 

outlet), and Alshourouq (Egypt). Employing Fairclough’s (1992) three-dimensional model of 

CDA, Halliday’s (1978) Systemic Functional Linguistics (SFL), and Kress and van Leeuwen’s 

(2006) grammar of visual design, the analysis reveals a profound disjuncture between Gaddafi’s 

linguistic self-fashioning and his mediated portrayal. Findings indicate that Gaddafi’s speech 

strategically deployed lexical choices, transitivity, and modality to construct identities of a 

rightful leader, paternal protector, and historical embodiment of Libya. Conversely, the selected 

newspapers, despite ideological nuances, converged on a representational framework depicting 

Gaddafi as weak, cowardly, and delegitimized, primarily through specific visual framing, 

camera angles, and captions. This study argues that the conflict between these representations 

is not merely descriptive but deeply ideological, reflecting the struggle for discursive hegemony 

during the Arab Spring, where control over narrative became a key battleground alongside 

military confrontation.

Libya is country of desert and the arid climate makes it in extreme lack of surface water .Groundwater then bececomes a very important resource to meet the economical and agricultural demand ,which believed to be comparatively much cleaner and free from poliution than surface water , water poliution is a state of deviation from pure condition .whereby its normal function and properties are affected .The present study is amied at assesses the bacteriologcal pollution of ground water samples used for humans and animals at different 11 localities in Tripoli rigion , Libya .This study related to the bacteriologcal analysis revealed high values of toral bacterial count in groundwater samples from both tanks (648.85 cfu/ml)and wells (394.34cfu/ml) than standard count imit (100cfu/ml)for driking water by EPA. Naarly similar values of MPN of coliform (58.00MPN/100ml) and E.coli bacteria (0.20) from both tanks and wells, other than zero number per 100 ml set by WHO .Finally , we did not find pathogenic bacteria as Salmonella and Enterococci bacteria , but there is very littel number of pathognic bacteria as Staphylocooccus aurous (1.50) and Pseudomonas aerugnosa (0.07) isoaled from both tanks and wells samples . Hence ,it was concluded that . This research to analysis the bacteriologcal pollution of grandwater used for hnmans and animals for some different localities of Tripoli , Libya with review to the hygienic standards and suggest an approach for imporing and prevent such contamination . Microbiological lested ground waters samples are good and mostly suitable for domestic uses. the coliform and pathogenic bacterial contamination render this water unsatisfactory for driking purposes unless bacteriologically perfactly treated ,if necessary for consideration for utility.
