خلفية البحث: مرض السكري هو عامل خطر لأمراض القلب والأوعية الدموية وتصلب الشرايين وسبب مهم للوفاة. يرتبط خلل الدهون في الدم بشكل شائع بمرض السكري من النوع الثاني ويعتبر مؤشر تصلب الشرايين في البلازما علامة قوية للتنبؤ بخطر الإصابة بتصلب الشرايين وأمراض القلب التاجية. الهدف من البحث: دراسة ارتباط المؤشرات الدهنية لتصلب الشرايين لدى المرضى العراقيين المصابين بالسكري من النوع الثاني ولديهم أمراض قلبية وعائية. المرضى وطرق العمل: أجريت هذه الدراسة السريرية في مستشفى بغداد التعليمي/ مدينة الطب - بغداد في الفترة من تشرين الأول 2022 ولغاية شباط 2023. تم مشاركة 60 مريضًا مصاباً بالسكري من النوع الثاني في هذه الدراسة. ثلاثون مريضا منهم كانوا يعانون من أمراض القلب والأوعية الدموية و 30 غير مصابين بأمراض القلب والأوعية الدموية. تراوحت أعمارهم بين 40-55 سنة. تم اختيار 30 فردًا سليما كمجموعة سيطرة. النتائج: كان هناك ارتفاع كبير في فحوصات نسبة السكر والدهون في الدم لدى مرضى السكري المصابين بأمراض القلب والأوعية الدموية مقارنة مع أولئك الذين لا يعانون من أمراض القلب والأوعية الدموية ومجموعة السيطرة. أظهرت النتائج الحالية مستويات مرتفعة من نسب الدهون لدى مرضى السكري المصابين بأمراض القلب والأوعية الدموية. كشفت النتائج أيضًا عن مستويات عالية من البروتين الدهني غير عالي الكثافة لدى مرضى السكري المصابين بأمراض القلب والأوعية الدموية (241.8 ± 12.24 ملغم/ ديسيلتر) مقابل (150.1 ± 7.12 و 68.9 ± 5.1 ملغم/ ديسيلتر) لأولئك الذين لا يعانون من أمراض القلب والأوعية الدموية ومجموعة السيطرة على التوالي. كان مؤشر تصلب الشرايين للبلازما لدى مرضى السكري المصابين بأمراض القلب والأوعية الدموية مقارنة بمجاميع مرضى السكري والأصحاء (0.8 ± 0.09) مقابل (0.7 ± 0.03 و 0.2 ± 0.08) على التوالي. كان هناك ارتباط معنوي موجب بين مؤشر تصلب الشرايين للبلازما والعوامل الجسمية، صورة السكر والدهون في الدم مع نسبها لدى مرضى السكري مع وبدون أمراض القلب والأوعية الدموية. الاستنتاجات: تؤكد نتائج هذه الدراسة أن مؤشرات الدهون هي مؤشرات خطر لضبط نسبة السكر في الدم بقيمة تنبؤية أعلى من العوامل التقليدية. أيضًا، ممكن اعتبار البروتين الدهني غير عالي الكثافة ومؤشر تصلب الشرايين في البلازما من العوامل الهامة للسيطرة على نسبة السكر في الدم.
Material obtained from the demolition of concrete structures and milling of flexible pavements has the highest potential for recyclability. This study aimed to evaluate the performance of hot mix asphalt with the concurrent use of recycled asphalt pavement (RAP) and recycled concrete aggregate (RCA). Contents of RAP and RCA were varied from 0% to 50% by fixing the total recycling materials percentage to 50%. Penetration grade 40/50 virgin binder and waste engine oil (WEO) as rejuvenator were used in the present study. A series of tests, such as Scanning electron microscopy (SEM), Marshall stability, indirect tensile strength test, IDEAL CT, uniaxial compression test, and resilient modulus test, were carried out to assess the performance of

Many biochemical changes occur in plants as a response to water stress, such as activation of antioxidant systems. Molybdenum (Mo) plays an important part in activating the expression of many enzymes, such as CAT, POD, and SOD, as well as increasing the proline content. Mo therefore supports the defence system in plants and plays an important role in the defence system of mung bean plants growing under water stress conditions. Four concentrations of Mo (0, 15, 30, and 45 mg·L−1) were applied to plants, using two approaches: (a) seed soaking and (b) foliar application. Mung bean plants were subject
... Show MoreIn this study, Zizphus spina-christi leaf powder was applied for the adsorption of methyl orange. The effect of different operating parameters on the Batch Process adsorption was investigated such as solution pH (2-12), effect of contact time (0-60 min.), initial dye concentration (2-20 mg/L), effect of adsorbent dosage (0-4.5 g) and effect of temperature (20-50ᵒC). The results show a maximum removal rate and adsorption capacity (%R= 23.146, qe = 2.778 mg/g) at pH = 2 and equilibrium was reached at 40 min. The pseudo- second-order kinetics were found to be best fit for the removal process (R2 = 0.997). Different isotherm models (Langmuir, Freundlich, Dubini-Radushkevich,Temkin) were applied in this stud
... Show MoreIn this study, manganese dioxide (MnO₂) nanoparticles (NPs) were synthesized via the hydrothermal method and utilized for the adsorption of Janus green dye (JG) from aqueous solutions. The effects of MnO₂ NPs on kinetics and diffusion were also analyzed. The synthesized NPs were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X-ray analysis (EDX), and Fourier-transform infrared spectroscopy (FT-IR), with XRD confirming the nanoparticle size of 6.23 nm. The adsorption kinetics were investigated using three models: pseudo-first-order (PFO), pseudo-second-order (PSO), and the intraparticle diffusion model. The PSO model provided the best fit (R² = 0.999), indicating that the adsorpti

Show MoreDetecting the optimum layer for well placement, which requires a diverse assortment of tools and techniques, represents a significant challenge in petroleum studies due to its critical impact on minimizing drilling costs and time. This study aims to evaluate integrated geological, petrophysical, seismic, and geomechanical data to identify the optimum zones for well placement. Three different reservoirs were analyzed to account for lateral and vertical variations in reservoir properties. The integrated data from these reservoirs provides many tools for reservoir development, especially to detect appropriate well placement zones based on evaluations of reservoir and geomechanical quality. The Mechanical Earth Model (MEM) was construct
... Show MoreA new adsorbent was developed by integrating algae biomass (AG) into a chitosan (CN) matrix, followed by structural enhancement via crosslinking with pyromellitic dianhydride (PMDA) through a hydrothermal synthesis approach. This process resulted in the formation of a robust AG@CN-PMDA composite with improved physicochemical characteristics suitable for advanced adsorption applications. The AG@CN-PMDA composite was evaluated for its efficiency in removal of the cationic dye methyl violet 2B (MV 2B) from aqueous solution. The adsorption process was refined through the Box-Behnken design (RSM-BBD), evaluating three essential parameters: adsorbent dosage (A: 0.02–0.1 g/100 mL), pH (B: 4–10), and time (C: 5–20 min). The ideal conditions f
