Advances in organometallic chemistry are crucial for improving the design of compounds to reduce toxic side effects and understand their mechanisms of action. The reaction of platinum(II) organometallic complexes with bidentate Schiff bases derived from 2-Hydroxynaphtalydeneaniline have been carried out. It concerns N,N’-naphtalidene para-nitroaniline (1-a), the, the N,N’-naphtalidene para-ethoxyaniline (1-b), the N,N’-naphtalideneaniline (1-c), the N,N’-naphtalidene para-chloroaniline (1-d) and the N,N’-naphtalidene para-methoxyaniline (1-e). The ligands were fully characterized by I.R., elemental analysis, 1H-NMR, 13C-NMR, ESI Mass Spectrometry and X-Ray Diffraction. The resulting metal complexes were obtained as a cationic species, through a simple substitution reaction, leading to two geometric isomers [1, 2], and characterized by IR, 1H-NMR, 13C-NMR, LIFDI Mass Spectrometry and supported by Elemental Analysis and X-Ray diffraction. Furthermore, a bimetallic platinum complex was prepared from the same ligands and dichloro(1,5-cyclooctadiene)platinum and characterized by X-Ray diffraction [3]The catalytic properties of the prepared platinum complexes in the hydrogenative and dehydrogenative silylation of styrene were investigated, and reaction kinetics conversion to products was determined by 1H-NMR and confirmed by GC-MS. This presentation will detail a comparison of the catalytic activity of five platinum organometallic complexes bearing different Schiff base ligands in the hydrosilylation of styrene, varying the experimental conditions of temperature, nature of the complex and the loading of the catalyst. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalysis" title="catalysis">catalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrosilylation" title=" hydrosilylation"> hydrosilylation</a>, <a href="https://publications.waset.org/abstracts/search?q=organometallic" title=" organometallic"> organometallic</a>, <a href="https://publications.waset.org/abstracts/search?q=schiff%20base" title=" schiff base"> schiff base</a> </p> <a href="https://publications.waset.org/abstracts/43642/application-of-a-series-of-new-platinum-organometallic-complexes-derived-from-bidentate-schiff-base-ligands-in-the-hydrogenative-and-dehydrogenative-silylation-of-styrene" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43642.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">254</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Screening of New Antimicrobial Agents from Heterocyclic Derivatives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Mazari">W.

In these last years, the incidence of these infections has risen sharply. Several microorganisms are the cause of these nosocomial infections and the emergence of resistance of the microbial strains against antibiotics creates a danger to public health. The search for new antimicrobial agents to overcome this problem has produced interesting compounds through chemical synthesis, which plays a very important role in the research and discovery of new drugs. It is in this framework that our study was conducted at our laboratory and it involves evaluating the antibacterial activity of thirteen 2-pyridone derivatives synthesized by two methods, the diffusion disc method and the dilution method against eight Gram negative bacterial strains. The results seem interesting especially for two products that have shown the best activities against Escherichia coli ATCC 25922 and Enterobacter cloacae ATCC 13047 with CMI of 512µg/ml. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heterocyclic%20derivatives" title="heterocyclic derivatives">heterocyclic derivatives</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20synthesis" title=" chemical synthesis"> chemical synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=biotechnology" title=" biotechnology"> biotechnology</a> </p> <a href="https://publications.waset.org/abstracts/5761/screening-of-new-antimicrobial-agents-from-heterocyclic-derivatives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5761.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">367</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Synthesis of a Serie of Metallic Complexes Derived from bis(4-Amino-5-Mercapto-1,2,4-Triazol-3-yl)butane with First Raw Transition Metals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Belbachir">I.

The bis-triazolic ligand was characterized by different spectroscopic studies, in order to enlighten its coordination mode, in the neutral and deprotonated forms, towards cobalt(II), nickel(II) and copper(II) sulfates, in both solution and solid state. The stoichiometry of the complexes [neutral BAMT-metal] and [deprotonated BAMT-metal] was first established in a solution of DMF with each of the three metallic cations and their complexation constants calculated, allowing us to compare the stability of the various prepared complexes. The various complexes were finally isolated in the solid state and the coordination mode of neutral and deprotonated BAMT explored towards each of the three metallic sulfates. The establishment of some ligand field parameters (Dq, B, β…) by electronic spectroscopy finally allowed to compare the coordination modes of BAMT towards each of the three metals and to highlight the influence of the deprotonation on the complexing properties of the bis-triazolic ligand. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=1" title="1">1</a>, <a href="https://publications.waset.org/abstracts/search?q=2" title="2">2</a>, <a href="https://publications.waset.org/abstracts/search?q=4-triazol" title="4-triazol">4-triazol</a>, <a href="https://publications.waset.org/abstracts/search?q=bis-1" title=" bis-1"> bis-1</a>, <a href="https://publications.waset.org/abstracts/search?q=2" title="2">2</a>, <a href="https://publications.waset.org/abstracts/search?q=4-triazol" title="4-triazol">4-triazol</a>, <a href="https://publications.waset.org/abstracts/search?q=metallic%20complexes" title=" metallic complexes"> metallic complexes</a>, <a href="https://publications.waset.org/abstracts/search?q=coordination%20in%20solution%20and%20solid%20state" title=" coordination in solution and solid state"> coordination in solution and solid state</a> </p> <a href="https://publications.waset.org/abstracts/43893/synthesis-of-a-serie-of-metallic-complexes-derived-from-bis4-amino-5-mercapto-124-triazol-3-ylbutane-with-first-raw-transition-metals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43893.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Selective Extraction of Couple Nickel(II) / Cobalt(II) by a Series of Schiff Bases in Sulfate Medium, in the Chloroforme-Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Belhadj">N.

This allowed to explore and to quantify in each of these media, some of their properties in solution such as, their acid-base behavior (determination and comparison of pKa), their distribution powers (determination and comparison of logKd), and their thermodynamic constants (determining ∆H°, ΔS° and ∆G°moy) by optimizing both the temperature and ionic strength. Study of the extraction of nickel (II) and cobalt(II) separately was undertaken in the aqueous-organic system, chloroform-water. Different extraction parameters have been thus optimized such, the pH, the concentration of extractant and the ionic strength, and the extraction constants established in each case.

The shear modulus, Young's modulus and Poisson's ratio for Ti, Zr, and Hf metals have were calculated and compared with the corresponding experimental values. Using elastic constants obtained from calculations GGA, the bulk modulus along the crystallographic axes of single crystals was calculated. This is in good agreement with experiment for Ti and Zr, whereas the hcp structure for Hf is a prediction. At zero temperature and zero pressure, the bcc crystal structure is found to be mechanically unstable for Ti, Zr, and Hf.

The surface quality, microstructure, impact energy and hardness of the prepared samples were investigated. Good surface quality and dispersion of nanoparticles were attained through employing sufficient processing conditions. The experimental results indicated that as the percentage of nanoparticles increased, the impact energy and hardness increased, reaching 2 kJ/m2 and 14.7 HV at a nanoparticle concentration of 25%, which means that the toughness and the hardness of the polymer-ceramic produced composite is higher than unprocessed PMMA by 66% and 33% respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20processing" title="friction stir processing">friction stir processing</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20matrix%20nanocomposite" title=" polymer matrix nanocomposite"> polymer matrix nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a> </p> <a href="https://publications.waset.org/abstracts/141761/microstructure-and-mechanical-evaluation-of-pmmaal2o3-nanocomposite-fabricated-via-friction-stir-processing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141761.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> The Plasma Additional Heating Systems by Electron Cyclotron Waves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghoutia%20Naima%20Sabri">Ghoutia Naima Sabri</a>, <a href="https://publications.waset.org/abstracts/search?q=Tayeb%20Benouaz"> Tayeb Benouaz </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The interaction between wave and electron cyclotron movement when the electron passes through a layer of resonance at a fixed frequency results an Electron Cyclotron (EC) absorption in Tokamak plasma and dependent magnetic field. This technique is the principle of additional heating (ECRH) and the generation of non-inductive current drive (ECCD) in modern fusion devices. In this paper we are interested by the problem of EC absorption which used a microscopic description of kinetic theory treatment versus the propagation which used the cold plasma description. The power absorbed depends on the optical depth which in turn depends on coefficient of absorption and the order of the excited harmonic for O-mode or X-mode. There is another possibility of heating by dissipation of Alfven waves, based on resonance of cold plasma waves, the shear Alfven wave (SW) and the compressional Alfven wave (FW). Once the (FW) power is coupled to (SW), it stays on the magnetic surface and dissipates there, which cause the heating of bulk plasmas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electron%20cyclotron" title="electron cyclotron">electron cyclotron</a>, <a href="https://publications.waset.org/abstracts/search?q=heating" title=" heating"> heating</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma" title=" plasma"> plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=tokamak" title=" tokamak"> tokamak</a> </p> <a href="https://publications.waset.org/abstracts/30668/the-plasma-additional-heating-systems-by-electron-cyclotron-waves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30668.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">513</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Production of a Sustainable Slow-Release Urea Fertilizer Using Starch and Poly-Vinyl Alcohol</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20M.%20H.%20Shokry">A.

One particular technique has been to coat urea fertilizer granules with less-soluble chemicals that permit the gradual release of nutrients in a slow and controlled manner. The aim of this research is to develop a biodegradable slow-release fertilizer (SRF) with materials that come from sustainable sources; starch and polyvinyl alcohol (PVA). The slow-release behavior and water retention capacity of the coated granules were determined. In addition, the aqueous release and absorbency rates were also tested. Results confirmed that the release rate from coated granules was slower than through plain membranes; and that the water absorption capacity of the coated urea decreased as PVA content increased. The SRF was also tested and gave positive results that confirmed the integrity of the product. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradability" title="biodegradability">biodegradability</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrogen-use%20efficiency" title=" nitrogen-use efficiency"> nitrogen-use efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=poly-vinyl%20alcohol" title=" poly-vinyl alcohol"> poly-vinyl alcohol</a>, <a href="https://publications.waset.org/abstracts/search?q=slow-release%20fertilizer" title=" slow-release fertilizer"> slow-release fertilizer</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/139377/production-of-a-sustainable-slow-release-urea-fertilizer-using-starch-and-poly-vinyl-alcohol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139377.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">214</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> The Behavior of Dam Foundation Reinforced by Stone Columns: Case Study of Kissir Dam-Jijel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Toufik%20Karech">Toufik Karech</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderahmen%20Benseghir"> Abderahmen Benseghir</a>, <a href="https://publications.waset.org/abstracts/search?q=Tayeb%20Bouzid"> Tayeb Bouzid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents a 2D numerical simulation of an earth dam to assess the behavior of its foundation after a treatment by stone columns.

For the evaluation of the pore pressures, the position of the phreatic line and the flow network was defined, and a seepage analysis was performed with the software MIDAS Soil Works. The consolidation calculation is performed through a simulation of the actual construction stages of the dam. These analyzes were performed using the Mohr-Coulomb soil model and the results are compared with the actual measurements of settlement gauges implanted in the dam.

However, its high cost is a major constraint, especially on the less windy sites. The purpose of wind energy systems is to maximize energy efficiency, and extract maximum power from the wind speed. In other words, having a power coefficient is maximum and therefore the maximum power point tracking. In this case, the MPPT control becomes important.To realize this control, strategy conventional proportional and integral (PI) controller is usually used. However, this strategy cannot achieve better performance. This paper proposes a robust control of a turbine which optimizes its production, that is improve the quality and energy efficiency, namely, a strategy of sliding mode control. The proposed sliding mode control strategy presents attractive features such as robustness to parametric uncertainties of the turbine; the proposed sliding mode control approach has been simulated on three-blade wind turbine. The simulation result under Matlab\Simulink has validated the performance of the proposed MPPT strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine" title="wind turbine">wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20power%20point%20tracking" title=" maximum power point tracking"> maximum power point tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20mode" title=" sliding mode"> sliding mode</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20conversion%20systems" title=" energy conversion systems"> energy conversion systems</a> </p> <a href="https://publications.waset.org/abstracts/21686/sliding-mode-control-of-variable-speed-wind-energy-conversion-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21686.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">611</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Mechanical and Hydraulic Behavior of Arid Zone Soils Treated with Lime: Case of Abadla, Bechar Clays, South of Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadek%20Younes">Sadek Younes</a>, <a href="https://publications.waset.org/abstracts/search?q=Fali%20Leyla"> Fali Leyla</a>, <a href="https://publications.waset.org/abstracts/search?q=Rikioui%20Tayeb"> Rikioui Tayeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Zizouni%20Khaled"> Zizouni Khaled</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stabilization of clay with lime as bearing stratum is an alternative to replacement of original soil.

The paper investigates the effect of hydrated lime on the behaviour of lime treated, arid zones clay (Abadla Clay). A number of mechanical and hydraulic tests were performed to identify the effect of lime dosage and compaction water content on the compressibility, permeability, and shear strength parameters of the soil. Test results show that the soil parameters can be improved through additives such as lime. Overall, the addition percentages of 6% and 9% lime give the best desired results. Also, results revealed that the compressibility behavior of lime-treated soil strongly affected by lime content. The results are presented in terms of modern interpretation of the behaviour of treated soils, in comparison with the parameters of the untreated soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arid%20zones" title="arid zones">arid zones</a>, <a href="https://publications.waset.org/abstracts/search?q=compressibility" title=" compressibility"> compressibility</a>, <a href="https://publications.waset.org/abstracts/search?q=lime" title=" lime"> lime</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20behaviour" title=" soil behaviour"> soil behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20stabilization" title=" soil stabilization"> soil stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=unsaturated%20soil" title=" unsaturated soil"> unsaturated soil</a> </p> <a href="https://publications.waset.org/abstracts/93366/mechanical-and-hydraulic-behavior-of-arid-zone-soils-treated-with-lime-case-of-abadla-bechar-clays-south-of-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93366.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">180</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Air Pollutants Assessment across the UAE Using Repeated Measures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karam%20Al-Assaf">Karam Al-Assaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Israa%20Al%20Khaffaf"> Israa Al Khaffaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Ryan%20Al%20Tayeb"> Ryan Al Tayeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayman%20Alzaatreh"> Ayman Alzaatreh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A significant, manageable hazard to public health, happiness, and the achievement of sustainable development is air pollution. Outdoor air pollution has increased globally over the previous years, exposing billions of people worldwide to hazardous air. With UAE being no different, there are a variety of pollution-related problems that need to be addressed. Therefore, to gain insights from the government and decision makers, this study aims to analyze the annual trends of the five major air pollutants (NO2, SO2, O3, CO, and PM10) across five emirates in the UAE (Abu Dhabi, Dubai, Sharjah, Ajman, and Ras AL Khaimah) from 2013 to 2020. The results of the analysis revealed that air pollutants NO2, SO2, and PM10 were significantly different across the years and states. Moreover, it was found that the levels of NO2 are significantly different in Dubai across the years. Moreover, the levels of SO2 are significantly different in Sharjah across the years. Furthermore, it was found that PM10 was significantly different in Ajman across the years. Moreover, the analysis of the significant difference in the pollutants in the three areas (Downtown, Residential, Industrial) revealed that there is no significant difference in the pollutant levels across the years in the three different areas. This tool has shown its effectiveness in monitoring pollutant trends, providing valuable data for government investigations and control measures across the UAE. Additionally, it serves as a valuable resource for decision-makers to develop and implement policies aimed at improving pollutant levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20pollution" title="air pollution">air pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20pollutant" title=" air pollutant"> air pollutant</a>, <a href="https://publications.waset.org/abstracts/search?q=repeated%20measures" title=" repeated measures"> repeated measures</a>, <a href="https://publications.waset.org/abstracts/search?q=MANOVA" title=" MANOVA"> MANOVA</a>, <a href="https://publications.waset.org/abstracts/search?q=UAE" title=" UAE"> UAE</a> </p> <a href="https://publications.waset.org/abstracts/175112/air-pollutants-assessment-across-the-uae-using-repeated-measures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175112.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Literature Review of the Antibacterial Effects of Salvia Officinalis L.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benguerine%20Zohra">Benguerine Zohra</a>, <a href="https://publications.waset.org/abstracts/search?q=Merzak%20Siham"> Merzak Siham</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouziane%20Cheimaa"> Bouziane Cheimaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Si%20Tayeb%20Fatima"> Si Tayeb Fatima</a>, <a href="https://publications.waset.org/abstracts/search?q=Jou%20Siham"> Jou Siham</a>, <a href="https://publications.waset.org/abstracts/search?q=Belkessam"> Belkessam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Antibiotics, widely produced and consumed in large quantities, have proven problematic due to various types of side effects. The development of bacterial resistance to currently available antibiotics has made the search for new antibacterial agents necessary. One alternative strategy to combat antibiotic-resistant bacteria is the use of natural antimicrobial substances such as plant extracts. The objective of this study is to provide an overview of the antibacterial effects of a plant native to the Middle East and Mediterranean regions, Salvia officinalis (sage). Materials and Methods: This review article was conducted by searching studies in the PubMed, Scopus, JSTOR, and SpringerLink databases. The search terms were "Salvia officinalis L." and "antibacterial effects." Only studies that met our inclusion criteria (in English, antibacterial effects of Salvia officinalis L., and primarily dating from 2012 to 2023) were accepted for further review. Results and Discussion: The initial search strategy identified approximately 78 references, with only 13 articles included in this review. The synthesis of the articles revealed that several data sources confirm the antimicrobial effects of S. officinalis. Its essential oil and alcoholic extract exhibit strong bactericidal and bacteriostatic effects against both Gram-positive and Gram-negative bacteria. Conclusion: The significant value of the extract, oil, and leaves of S. officinalis calls for further studies on the other useful and unknown properties of this multi-purpose plant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=salvia%20officinalis" title="salvia officinalis">salvia officinalis</a>, <a href="https://publications.waset.org/abstracts/search?q=literature%20review" title=" literature review"> literature review</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial" title=" antibacterial"> antibacterial</a>, <a href="https://publications.waset.org/abstracts/search?q=effects" title=" effects"> effects</a> </p> <a href="https://publications.waset.org/abstracts/186196/literature-review-of-the-antibacterial-effects-of-salvia-officinalis-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186196.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">38</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Degradation of Different Organic Contaminates Using Corona Discharge Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20H.%20El-Shazly">A.

This work examines the possibility of increasing the organic pollution removal efficiency from wastewater using non-thermal plasma. Three types of organic pollution phenol, acid blue 25 and methylene blue are presented to investigate experimentally the amount of organic pollution removal efficiency from wastewater. Measurement results for phenol degradation percentage are 71% in 35 min and 96% when its residence time is 60 min. In addition, the degradation behavior of acid blue 25 utilizing dual pin-to-plate corona discharge plasma system displays a removal efficiency of 82% in 11 min. The complete decolorization was accomplished in 35 min for concentration of acid blue 25 up to 100 ppm. Furthermore, the methylene blue degradation touched up to 85% during 35 min treatment in corona discharge plasma a batch reactor system. The decolorization ratio, conductivity, corona current and discharge energy are considered at various concentration molarity for AlCl3, CaCl2, KCl and NaCl under different molar concentration. It was observed that the attendance of salts at the same concentration level considerably diminished the rate and the extent of decolorization. The research presented that the corona system could be positively utilized in a diversity of organically contaminated at diverse concentrations. Energy consumption requirements for decolorization was considered. The consequences will be valuable for designing the plasma treatment systems appropriate for industrial wastewaters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wastewater%20treatment" title="wastewater treatment">wastewater treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=corona%20discharge" title=" corona discharge"> corona discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=non-thermal%20plasma" title=" non-thermal plasma"> non-thermal plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20pollution" title=" organic pollution"> organic pollution</a> </p> <a href="https://publications.waset.org/abstracts/52495/degradation-of-different-organic-contaminates-using-corona-discharge-plasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52495.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">338</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Study of Complex (CO) 3Ti (PHND) and CpV (PHND) (PHND = Phénanthridine)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akila%20Tayeb-Benmachiche">Akila Tayeb-Benmachiche</a>, <a href="https://publications.waset.org/abstracts/search?q=Saber-Mustapha%20Zendaoui"> Saber-Mustapha Zendaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Salah-Eddine%20Bouaoud"> Salah-Eddine Bouaoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Bachir%20Zouchoune"> Bachir Zouchoune </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The variation of the metal coordination site in π-coordinated polycyclic aromatic hydrocarbons (PAH) corresponds to the haptotropic rearrangement or haptotropic migration in which the metal fragment MLn is considered as the moveable moiety that is shifted between two rings of polycyclic or heteropolycyclic ligands. These structural characteristics and dynamical properties give to this category of transition metal complexes a considerable interest. We have investigated the coordination and the haptotropic shifts of (CO)3Ti and CpV moieties over the phenanthridine aromatic system and according to the metal atom nature. The optimization of (CO)3Ti(PHND) and CpV(PHND), using the Amsterdam Density Functional (ADF) program, without a symmetrical restriction of geometry gives an η6 coordination mode of the C6 and C5N rings, which in turn give rise to a six low-lying deficient 16-MVE of each (CO)3Ti(PHND) and CpV(PHND) structure (three singlet and three triplet state structures for Ti complexes and three triplet and three quintet state structures for V complexes). Thus, the η6–η6 haptotropic migration of the metal fragment MLn from the terminal C6 ring to the central C5N ring has been achieved by a loss of energy. However, its η6–η6 haptotropic migration from central C5N ring to the terminal C6 rings has been accomplished by a gain of energy. These results show the capability of the phenanthridine ligand to adapt itself to the electronic demand of the metal in agreement with the nature of the metal–ligand bonding and demonstrate that this theoretical study can also be applied to large fused π-systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electronic%20structure" title="electronic structure">electronic structure</a>, <a href="https://publications.waset.org/abstracts/search?q=bonding%20analysis" title=" bonding analysis"> bonding analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=density%20functional%20theory" title=" density functional theory"> density functional theory</a>, <a href="https://publications.waset.org/abstracts/search?q=coordination%20%20chemistry%20haptotropic%20migration" title=" coordination chemistry haptotropic migration "> coordination chemistry haptotropic migration </a> </p> <a href="https://publications.waset.org/abstracts/38303/study-of-complex-co-3ti-phnd-and-cpv-phnd-phnd-phenanthridine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38303.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> The Therapeutic Rise of Turmeric: From Spice to Medicine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Merzak%20Siham">Merzak Siham</a>, <a href="https://publications.waset.org/abstracts/search?q=Benguerine%20Zohra"> Benguerine Zohra</a>, <a href="https://publications.waset.org/abstracts/search?q=Si%20Tayeb%20Fatima"> Si Tayeb Fatima</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouzian%20Chaimaa%20Affaf"> Bouzian Chaimaa Affaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Jou%20Siham"> Jou Siham</a>, <a href="https://publications.waset.org/abstracts/search?q=Belkessam%20Nafissa"> Belkessam Nafissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Medicinal plants, particularly spices, are essential for pharmacological research due to their health benefits. This study focuses on Curcuma longa, a spice recognized for its therapeutic properties. Materials and Methods: This study is based on a thorough search conducted on Google Scholar, PubMed, and ScienceDirect. From an initial selection of 25 articles, five were chosen to extract relevant information on Curcuma longa. Results and Discussions: Clinical studies have indicated that curcumin is well tolerated at doses up to 12 g/day. Its anti-rheumatic efficacy was compared to phenylbutazone in 18 individuals. Each participant received a daily dose of either 1200 mg of curcumin or 300 mg of phenylbutazone for 2 weeks. Curcumin was well tolerated at this dose and demonstrated activity comparable to phenylbutazone. Additionally, a study on 62 patients showed that curcumin sustainably relieved symptoms without toxicity. Its effects included reduced itching, lesions, and pain. In ten volunteers, administering 500 mg of curcumin for seven days resulted in a 33% decrease in lipid peroxidation, a 29% increase in HDL cholesterol, and a 12% decrease in total cholesterol. It is important to note that curcumin is a potent, selective inhibitor of phosphorylase kinase, an increased marker in psoriasis. Conclusion: Curcumin is promising as a future drug for various diseases, but its bioavailability must be improved through techniques such as nano encapsulation. Additionally, exploring chemical derivatives of curcumin could lead to more potent and targeted molecules. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=turmeric" title="turmeric">turmeric</a>, <a href="https://publications.waset.org/abstracts/search?q=spice" title=" spice"> spice</a>, <a href="https://publications.waset.org/abstracts/search?q=medicinal%20plants" title=" medicinal plants"> medicinal plants</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmacological%20activities." title=" pharmacological activities."> pharmacological activities.</a> </p> <a href="https://publications.waset.org/abstracts/187066/the-therapeutic-rise-of-turmeric-from-spice-to-medicine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187066.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">35</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Radon-222 Concentration and Potential Risk to Workers of Al-Jalamid Phosphate Mines, North Province, Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=El-Said.%20I.%20Shabana">El-Said.

Due to their different pathways in the environment, the <sup>238</sup>U/<sup>232</sup>Th activity concentration ratio usually found to be greater than unity in phosphate sediments. The presence of these radionuclides creates a potential need to control exposure of workers in the mining and processing activities of the phosphate minerals in accordance with IAEA safety standards. The greatest dose to workers comes from exposure to radon, especially <sup>222</sup>Rn from the uranium series, and has to be controlled. In this regard, radon (<sup>222</sup>Rn) was measured in the atmosphere (indoor and outdoor) of Al-Jalamid phosphate-mines working area using a portable radon-measurement instrument RAD7, in a purpose of radiation protection. Radon was measured in 61 sites inside the open phosphate mines, the phosphate upgrading facility (offices and rooms of the workers, and in some open-air sites) and in the dwellings of the workers residence-village that lies at about 3 km from the mines working area. The obtained results indicated that the average indoor radon concentration was about 48.4 Bq/m<sup>3</sup>. Inside the upgrading facility, the average outdoor concentrations were 10.8 and 9.7 Bq/m<sup>3</sup> in the concentrate piles and crushing areas, respectively. It was 12.3 Bq/m<sup>3</sup> in the atmosphere of the open mines. These values are comparable with the global average values. Based on the average values, the annual effective dose due to radon inhalation was calculated and risk estimates have been done. The average annual effective dose to workers due to the radon inhalation was estimated by 1.32 mSv. The potential excess risk of lung cancer mortality that could be attributed to radon, when considering the lifetime exposure, was estimated by 53.0x10<sup>-4</sup>. The results have been discussed in detail. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dosimetry" title="dosimetry">dosimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20monitoring" title=" environmental monitoring"> environmental monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphate%20deposits" title=" phosphate deposits"> phosphate deposits</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20protection" title=" radiation protection"> radiation protection</a>, <a href="https://publications.waset.org/abstracts/search?q=radon" title=" radon"> radon</a> </p> <a href="https://publications.waset.org/abstracts/52996/radon-222-concentration-and-potential-risk-to-workers-of-al-jalamid-phosphate-mines-north-province-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52996.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">272</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Determinants of Stone Free Status After a Single Session of Flexible Ureteroscopy with Laser Lithotripsy for Renal Calculi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elkoushy">Mohamed Elkoushy</a>, <a href="https://publications.waset.org/abstracts/search?q=Sameer%20Munshi"> Sameer Munshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Waseem%20Tayeb"> Waseem Tayeb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Flexible ureteroscopy (fURS) has dramatically improved the minimally invasive management of complex nephrolithiasis. fUR is increasingly being used as the first-line treatment for patients with renal stones. Stone-free status (SFS) is the primary goal in the management of patients with urolithiasis. However, substantial variations exist in the reported SFS following fURS. Objectives: This study determines the predictors of SFS after a single session of fURS with holmium laser lithotripsy (HLL) for renal calculi. Methods: A retrospective review of prospectively collected data was performed for all consecutive patients undergoing fURS and HLL for renal calculi at a tertiary care center. Patients with previous ipsilateral URS for the same stones were excluded. All patients underwent JJ ureteral stent insertion at the end of the procedure. SFS was defined as the presence of no residuals or ≤4-mm non-obstructing stone and was assessed by CT/KUB imaging after 3-4 weeks post-operatively. Multivariate logistic regression was used to detect possible predictors of SFS. Results: A total of 212 patients were included with a mean age of 52.3±8.3 years and a stone burden <20 mm (49.1%), 20-30 mm (41.0%) and >30 mm (9.9%). Overall SFS after a single session of fURS was 71.7%, 92% and 52% for stones less and larger than 20 mm, respectively. Patients with stones> 20 mm need retreatment with a mean number of 1.8 (1.3-2.7) fURS. SFS was significantly associated with male gender, stone bulk <20 mm (95.7% vs. 56.2%), non-lower pole stones, hydronephrotic kidney, low stone intensity, ureteral access sheath, and preoperative stenting. SFS was associated with a lower readmission rate (5.9% vs. 38.9%) and urinary tract infections (3.8% vs. 25.9%). In multivariate regression analysis, SFS maintains its significant association with low stone burden of <20 mm (OR: 5.21), stone intensity <600 HFU (OR: 2.87), and non-lower caliceal stones (OR: 3.84). Conclusion: Best results after a single-session fURS for renal stone were obtained for the stone burden of less than 20 mm and low stone attenuation. Lower calyceal stones may influence stone clearance and need a different approach than fURS, especially for higher stone burden. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ureteroscopy" title="ureteroscopy">ureteroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=kidney%20stone" title=" kidney stone"> kidney stone</a>, <a href="https://publications.waset.org/abstracts/search?q=lithotripsy" title=" lithotripsy"> lithotripsy</a>, <a href="https://publications.waset.org/abstracts/search?q=stone-free" title=" stone-free"> stone-free</a>, <a href="https://publications.waset.org/abstracts/search?q=predictors" title=" predictors"> predictors</a> </p> <a href="https://publications.waset.org/abstracts/192556/determinants-of-stone-free-status-after-a-single-session-of-flexible-ureteroscopy-with-laser-lithotripsy-for-renal-calculi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192556.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">18</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> In Silico Analysis of Deleterious nsSNPs (Missense) of Dihydrolipoamide Branched-Chain Transacylase E2 Gene Associated with Maple Syrup Urine Disease Type II</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zainab%20S.%20Ahmed">Zainab S.

The development of disease has been associated with SNPs in the DBT gene. Despite that, the computational analysis of SNPs in coding and noncoding and their functional impacts on protein level still remains unknown. Hence, in this study, we carried out a comprehensive in silico analysis of missense that was predicted to have a harmful influence on DBT structure and function. In this study, eight different in silico prediction algorithms; SIFT, PROVEAN, MutPred, SNP&GO, PhD-SNP, PANTHER, I-Mutant 2.0 and MUpo were used for screening nsSNPs in DBT including. Additionally, to understand the effect of mutations in the strength of the interactions that bind protein together the ELASPIC servers were used. Finally, the 3D structure of DBT was formed using Mutation3D and Chimera servers respectively. Our result showed that a total of 15 nsSNPs confirmed by 4 software (R301C, R376H, W84R, S268F, W84C, F276C, H452R, R178H, I355T, V191G, M444T, T174A, I200T, R113H, and R178C) were found damaging and can lead to a shift in DBT gene structure. Moreover, we found 7 nsSNPs located on the 2-oxoacid_dh catalytic domain, 5 nsSNPs on the E_3 binding domain and 3 nsSNPs on the Biotin Domain. So these nsSNPs may alter the putative structure of DBT’s domain. Furthermore, we detected all these nsSNPs are on the core residues of the protein and have the ability to change the stability of the protein. Additionally, we found W84R, S268F, and M444T have high significance, and they affected Leucine, Isoleucine, and Valine, which reduces or disrupt the function of BCKD complex, E2-subunit which the DBT gene encodes. In conclusion, based on our extensive in-silico analysis, we report 15 nsSNPs that have possible association with protein deteriorating and disease-causing abilities. These candidate SNPs can aid in future studies on Maple Syrup Urine Disease type II base in the genetic level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DBT%20gene" title="DBT gene">DBT gene</a>, <a href="https://publications.waset.org/abstracts/search?q=ELASPIC" title=" ELASPIC"> ELASPIC</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20silico%20analysis" title=" in silico analysis"> in silico analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=UCSF%20chimer" title=" UCSF chimer"> UCSF chimer</a> </p> <a href="https://publications.waset.org/abstracts/83720/in-silico-analysis-of-deleterious-nssnps-missense-of-dihydrolipoamide-branched-chain-transacylase-e2-gene-associated-with-maple-syrup-urine-disease-type-ii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83720.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">201</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Genome Sequencing and Analysis of the Spontaneous Nanosilver Resistant Bacterium Proteus mirabilis Strain scdr1</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amr%20Saeb">Amr Saeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Al-Rubeaan"> Khalid Al-Rubeaan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abouelhoda"> Mohamed Abouelhoda</a>, <a href="https://publications.waset.org/abstracts/search?q=Manojkumar%20Selvaraju"> Manojkumar Selvaraju</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamsa%20Tayeb"> Hamsa Tayeb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: P. mirabilis is a common uropathogenic bacterium that can cause major complications in patients with long-standing indwelling catheters or patients with urinary tract anomalies. In addition, P. mirabilis is a common cause of chronic osteomyelitis in diabetic foot ulcer (DFU) patients. Methodology: P. mirabilis SCDR1 was isolated from a diabetic ulcer patient.

The enzyme is responsible for the metabolism and elimination of approximately 25% of clinically used drugs, especially in breast cancer and psychiatric therapy. Different phenotypes have been described displaying alleles that lead to a complete loss of enzyme activity, reduced function (poor metabolizers – PM), hyperfunctionality (ultrarapid metabolizers–UM) and therefore drug intoxication or loss of drug effect. The prevalence of these variants may vary among different ethnic groups. Furthermore, the xTAG system has been developed to categorized all patients into different groups based on their CYP2D6 substrate metabolization. Aim of the study: To determine the prevalence of the different CYP2D6 variants in our population, and to evaluate their clinical relevance in personalized medicine. Methodology: We used the Luminex xMAP genotyping system to sequence 305 Saudi individuals visiting the Blood Bank of our Institution and determine which polymorphisms of CYP2D6 gene are prevalent in our region. Results: xTAG genotyping showed that 36.72% (112 out of 305 individuals) carried the CYP2D6_*2. Out of the 112 individuals with the *2 SNP, 6.23% had multiple copies of *2 SNP (19 individuals out of 305 individuals), resulting in an UM phenotype. About 33.44% carried the CYP2D6_*41, which leads to decreased activity of the CYP2D6 enzyme. 19.67% had the wild-type alleles and thus had normal enzyme function. Furthermore, 15.74% carried the CYP2D6_*4, which is the most common nonfunctional form of the CYP2D6 enzyme worldwide. 6.56% carried the CYP2D6_*17, resulting in decreased enzyme activity. Approximately 5.73% carried the CYP2D6_*10, consequently decreasing the enzyme activity, resulting in a PM phenotype. 2.30% carried the CYP2D6_*29, leading to decreased metabolic activity of the enzyme, and 2.30% carried the CYP2D6_*35, resulting in an UM phenotype, 1.64% had a whole-gene deletion CYP2D6_*5, thus resulting in the loss of CYP2D6 enzyme production, 0.66% carried the CYP2D6_*6 variant. One individual carried the CYP2D6_*3(B), producing an inactive form of the enzyme, which leads to decrease of enzyme activity, resulting in a PM phenotype. Finally, one individual carried the CYP2D6_*9, which decreases the enzyme activity. Conclusions: Our study demonstrates that different CYP2D6 variants are highly prevalent in ethnic Saudi Arabs. This finding sets a basis for informed genotyping for these variants in personalized medicine. The study also suggests that xTAG is an appropriate procedure for genotyping the CYP2D6 variants in personalized medicine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CYP2D6" title="CYP2D6">CYP2D6</a>, <a href="https://publications.waset.org/abstracts/search?q=hormonal%20breast%20cancer" title=" hormonal breast cancer"> hormonal breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmacogenetics" title=" pharmacogenetics"> pharmacogenetics</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=psychiatric%20treatment" title=" psychiatric treatment"> psychiatric treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20population" title=" Saudi population"> Saudi population</a> </p> <a href="https://publications.waset.org/abstracts/22860/prevalence-of-cyp2d6-and-its-implications-for-personalized-medicine-in-saudi-arabs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22860.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">572</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Effect of Nigella Sativa Seeds and Ajwa Date on Blood Glucose Level in Saudi Patients with Type 2 Diabetes Mellitus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reham%20Algheshairy">Reham Algheshairy</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Tayeb"> Khaled Tayeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Smith"> Christopher Smith</a>, <a href="https://publications.waset.org/abstracts/search?q=Rebecca%20Gregg"> Rebecca Gregg</a>, <a href="https://publications.waset.org/abstracts/search?q=Haruna%20Musa"> Haruna Musa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Diabetes is a medical condition that refers to the pancreas’ inability to secrete sufficient insulin levels, a hormone responsible for controlling glucose levels in the body. Any surplus glucose in the blood stream is excreted through the urinary system. Insulin resistance in blood cells can also cause this condition despite the fact that the pancreas is producing the required amount of insulin A number of researchers claim that the prevalence of diabetes in Saudi Arabia has reached epidemic proportions, although one study did observe one positive in the rise in the awareness of diabetes, possibly indicative of Saudi Arabia’s improving healthcare system. While a number of factors can cause diabetes, the ever-increasing incidence of the disease in Saudi Arabia has been blamed primarily on low levels of physical activity and high levels of obesity. Objectives: The project has two aims. The first aim of the project is to investigate the regulatory effects of consumption of Nigella seeds and Ajwah dates on blood glucose levels in diabetic patients with type 2 diabetes. The second aim of the project is to investigate whether these dietary factors may have potentially beneficial effects in controlling the complications that associated with type 2 diabetes. Methods: This use a random-cross intervention trail of 75 Saudi male and female with type 2 diabetes in Al-Noor hospital in Makkah ( KSA) aged between 18 and 70 years were divided into 3 groups. Group 1 will consume 2g of Nigella Sativa seeds daily along with a modified diet for 12 weeks, group 2 will be given Ajwah dates daily with a modified diet for 12 weeks and group 3 will follow a modified diet for 12 weeks. Anthropometric measurements were taken at baseline, along with bloods for HbA1c, fasting blood sugar and at the end of 12 weeks. Results: This study found significant decrease in blood level (FBG & 2PPBG) and HbA1c in the groups with diet and Nigella seeds) compared to Ajwa date. However, there is no significant change were found in HbA1c, FBG and 2hrpp regarding Ajwa group. Conclusion: This study illustrated a significant improvement in some markers of glycaemia following 2 g of Ns and diet for 12 weeks. The dose of 2g/day of consumed Nigella seeds was found to be more effective in controlling BGL and HbA1c than control and Ajwa groups. This suggests that Nigella seeds and following a diet may have a potential effect (a role in controlling outcomes for type 2 diabetes and controlling the disease). Further research is needed on a large scale to determine the optimum dose and duration of Nigella and Ajwa in order to achieve the desired results. <p class="card-text"><strong>Keywords:</strong> <a
