Evaluation of the Antibiofilm Activity of Laurus nobilis Leaves Extract and Assessment of Its Effect on fimA and papC genes in Escherichia coli isolates
...Show More Authors

Background: The beneficial gut bacterium E. coli can cause blood poisoning, diarrhoea, and other gastrointestinal and systemic disorders. Objective: This study amid to examines the antibiofilm activity of Laurus nobilis leaves extract on E. coli isolates and compares pre- and post-treatment gene expression of fimA and papC genes. Subjects and Methods: Ten isolates of E. coli were obtained from the Genetic Engineering and Biotechnology Institute, University of Baghdad, which was previously collected from Baghdad city hospitals and diagnosed by chemical tests, the diagnosis was confirmed using VITEK-2 System. The preparation of the aqueous and methanolic Laurus nobilis leaves extracts was done by using the maceration method and Soxhlet apparatus respectively. HPLC were conducted to determine the active compounds in the extracts. Moreover, molecular detection of fimA and papC genes and analysis of the gene expression by comparing the isolates treated with sub MIC of methanolic L. nobilis leaves extract with the untreated isolates. Results: Methanolic and aqueous extracts contained alkaloids, tannins, phenols, saponins, flavonoids, and glycosides. Seven polyphenolic compounds, four flavonoids derivatives (Apigenin, Luteolin, Rutin, and kaempferol) and three phenolic acids (Caffeic acid, Gallic acid, and Syringic acid), were identified by matching retention time with the standards. Laurus nobilis methanolic leaf extract inhibited 90% and 100% of E. coli biofilm development at 32 and 64 mg/ml. Conclusion: The result of the gene expression revealed that there is a decrease in the expression of the fimA and papC genes. The present study concluded that the Laurus nobilis leaves extract have rich phytochemical contents, so the methanolic extract had an excellent reduction effect on biofilm formation and showed remarkable down-regulation on the papC and fimA genes, which are responsible for the biofilm formation in E. coli.

Hiding Multi Short Audio Signals in Color Image by using Fast Fourier Transform
...Show More Authors

Many purposes require communicating audio files between the users using different applications of social media. The security level of these applications is limited; at the same time many audio files are secured and must be accessed by authorized persons only, while, most present works attempt to hide single audio file in certain cover media. In this paper, a new approach of hiding three audio signals with unequal sizes in single color digital image has been proposed using the frequencies transform of this image. In the proposed approach, the Fast Fourier Transform was adopted where each audio signal is embedded in specific region with high frequencies in the frequency spectrum of the cover image to sa

Optical Power Distributions for 4×4 MIMO Visible Light Communications in Indoor Environment
...Show More Authors

Visible Light Communication (VLC) has emerged as a powerful technique for wireless communication systems. Providing high data rate and increasing capacity are the major problems in VLC. Recent evidence suggests that Multiple Input Multiple Output (MIMO) technique can offers improved data rates and increased link range. This paper describes the design and implementation of visible light communication system in indoor environment exploring the benefits of MIMO. The specific objective of this research was to implement a 4× 4 Multiple Input (LEDs) Multiple Output (photodetectors)-VLC communication system, where a 16 white power LEDs in four arrays are setting up at transmitter and four RX modules are setting up at receiver side without the nee

...Show More Authors

Post-structural critical studies highlighted the importance of studying the texts surrounding the text as an important part in the process of receiving and understanding texts, and although this topic was dealt with by the ancient Arabs and Europeans, interest in it appeared clearly after the appearance of Gerard Genet's book (SEUILS), which separated it Text Thresholds. Or what he called paratexte, and dealt with them with interest as he reads them on books. With the development of semiotic studies, interest in paratexte studies began in a broader way and in various literary and non-literary texts, including journalistic texts. And since specialized magazines are one of the press releases that enjoy their privacy in terms of topics and
