Nowadays, the usage of NSAIDs has been increased dramatically for relieving pain and the treatment of divers inflammatory conditions, therefore, it is necessary to develop this class of drug by increasing their activity and decreasing their side effects. Their most common side effect is the gastrointestinal disorders, especially, gastric bleeding resulting from the inhibition of prostaglandins synthesis.


Artificial intelligence review:
Research summary
تتناول هذه الدراسة تصميم مضاهئات جديدة لمركب نيمسوليد باستخدام تقنيات النمذجة الجزيئية وتصميم الأدوية بمساعدة الحاسوب. يهدف البحث إلى تحسين فعالية نيمسوليد وتقليل آثاره الجانبية، خاصة تلك المتعلقة بالجهاز الهضمي. تم التركيز على تحسين انتقائية المركبات تجاه إنزيم السيكلوأوكسجيناز-2 (COX-2) لتقليل التأثيرات الجانبية غير المرغوبة. تم استخدام برنامج AutoDock Vina لإجراء عمليات الترسية وحساب طاقة الارتباط بين المضاهئات المصممة وإنزيم COX-2. أظهرت النتائج أن إضافة ذرة فلور في الموضع بارا بالنسبة لمجموعة الفِنوكسي وزمرة ميثيل في الموضع ميتا على حلقة البنزن الثانية قد حسنت من طاقة الارتباط. تم الحصول على مضاهئات ذات طاقة ارتباط أفضل من نيمسوليد، مما يشير إلى إمكانية تطوير مضادات التهاب غير ستيرويدية جديدة بفعالية أكبر وآثار جانبية أقل.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو تحسين فعالية نيمسوليد وتقليل آثاره الجانبية، إلا أن هناك بعض النقاط التي يمكن مناقشتها. أولاً، تعتمد الدراسة بشكل كبير على النمذجة الجزيئية والترسية الافتراضية، والتي قد لا تعكس بدقة التفاعلات الحيوية في الجسم الحي. لذلك، من المهم إجراء تجارب مختبرية وحيوية لتأكيد النتائج. ثانياً، لم يتم التطرق بشكل كافٍ إلى الآثار الجانبية المحتملة للمضاهئات الجديدة، خاصة فيما يتعلق بالسمية الكبدية التي يعاني منها نيمسوليد. أخيراً، يمكن أن تكون الدراسة أكثر شمولية إذا تم تضمين تحليلات إضافية مثل الديناميكا الجزيئية لتقديم فهم أعمق للتفاعلات بين المضاهئات وإنزيم COX-2.

Compounds, showing selectivity towards COX-2, are promising agents as selective non-steroidal anti-inflammatory drugs (NSAIDs) with lower side effects, especially, gastrointestinal ones. However, recent reports reveal the cardiovascular side effec ts associated with the selective COX-2 inhibitors. Therefore, attempts have been done to develop the second generation of selective COX-2 inheritors. They have safer profile compared to the first generation. Lumiracoxib belongs to this class of compounds. In this study, the molecular structure of the target enzymes were prepared. Library of rationally designed lumiracoxib analogues were docked.
Nowadays, glycogen synthase kinase 3 (GSK-3) inhibitors become one of the most important drug targets for the development of their selective inhibitors serving as promising drugs for the treatment of many diseases, particularly Alzheimer's disease . Targeting GSK-3 enzyme has a therapeutic importance in many diseases and is one of the valuable fields for researchers in both academic research centers and pharmaceutical companies.
This paper addresses the subject of design changes management in the context of a multidisciplinary collaborative Building Information Models (BIM) environment. Within Building projects organization field, This research aims to use change managemen t as tool for design and decision making. The proposed method for the management of design changes depends on both modeling the elements of structure based on BIM and using parameter-based design structure matrix as tool for Change Management in a way that will support the effective flow of information between disciplines, and thus reduces design changes, and will be able to trace a series of successive changes within the BIM environment. This paper offers different necessary models to build the DSM; then they are fed by the information of a commercial building project collected from design engineers. The proposed method represents the various dependencies between the parameters of building and evaluates their impact on the levels of elements, the whole system and subsystems in a way that allows to identify the critical parameters and predict some of the iterative cycles of change to avoid unnecessary rework.
In the framework of the increasing awareness about environmental issues, The reasons behind the worsening greenhouse gas emissions, And the great attrition Of nonrenewable natural resources In the operation of residential, commercial, industrial, a nd other,Research came within the concept of green architecture, And green building requirements, The most important reasons behind the support of the Global Environment organizations About the support and guide the development of architects, and specialists mechanism To adopt the architecture is able to achieve a balance between the buildings sector and between the natural environment surrounding it, And make available resources in the environment part of the design program, to mitigate the adverse impact of the buildings and the elimination of diseased cities. The research focuses on international experiences based green eco-friendly home design, And using the latest technological techniques available, And which help to achieve the goal of the designer in the creation of an appropriate healthy dwelling for a person practiced by the various activities complete the well-being and applied sustainability in all its aspects, For use in the development of the current reality in our society and to transform our housing more convenient healthy buildings.
Driving simulators are valuable research tool for conducting driving studies instead of conducting these studies on the real roads. However, to be accepted as a representative of the real world, a driving simulator must provide an acceptable degree o f realism. It is always a goal of the designers of driving simulators to increase their degree of realism as possible. However, increasing the realism of a driving simulator leads to increasing its cost beyond the allocated cost. So it is common to build a driving simulator initially with an acceptable degree of realism and then have it undergo continuous changes to increase its realism whenever there is a chance to do so. The objective of this paper is to present a modular design of the software components of a fixed-base driving simulator. By following this design, it is possible to start building a simulator with a degree of realism that can continually be increased by improving each of the software components alone without the need to radically change other components of the simulator. This design also helps to build economical alternatives while conducting a study on a simulator and to collect the experiment data by providing specialized software components for these tasks.
