الحمد لله رب العالمين، حمداً يوافي نِعَمَهُ ويُكافئُ مزيدَه، والصلاةُ والسلامُ على سيدِ الأنامِ وإمام المرسَلين، سيدِنا محمدٍ الصادق الأمين. نسأل الله تعالى أن يعلّمَنا ما ينفعُنا وينفعَنا بما علّمَنا، وأن يُعيننا متعلمين ومعلمين على التأدب بأدب القرآن الكريم.

أما بعد، فالعلم هبة الله، وهبة الله لا تُعطى إلا لمن يُعطي من نفسه وقتاً وجهداً وصبراً، لذا قيل: (إنَّ العِلْمَ لا يُعطيكَ بَعضَه

كان النبي (r) العابد المتحنّث، ورجل السياسة الذي شيّد أمة من الفتات المتناثر، ورجلَ حربٍ يضع الخطط ويقود الجيوش، وأباً حنوناً عطوفاً، وزوجاً تحققت فيه المودة والرحمة والسكن، وصديقاً رحيماً، وقريباً كريماً، وجاراً تشغله هموم جيرانه، وحاكماً تملأ نفسه مشاعر محكوميهِ، يعودُهم ويزورُهم ويُعينُهم، ويمنحهم من مودته وعطفه ما يجعلهم يفتدونه بأنفسهم، ومع هذا كله فهو قائم على أعظم دعوةٍ شهدت

Background: Survey of the occlusion in population groups usually include in their objections the academic assessment of occlusal feature, the planning resources for public health treatment programmers, the comparison of different population and the screening of groups for orthodontic treatment. Likewise a thorough investigation of the occurrence of malocclusions among school–students would be of major importance in the planning of orthodontic treatment in the public dental health services. For this purpose it is necessary to have detailed information on the prevalence of individual malocclusion among boys and girls at different ages distributed regionally, and moreover, an analysis of the need for orthodontic treatment in the different sc

In this part of programme , different bacterial isolates mainly Salmonella spp, Shigella spp and Escherichia coli were used for antagonism with Saccharomyces boulardii under different conditions . S.boulardii was grown under aerobic conditions and antagonized with young overnight nutrient broth cultures of test bacterial isolates and other kept in refrigerator for a week after full growth . Young cultures were more susceptible to antagonistic effect of yeast compared to old cultures and on isolates grown on solid medium for 24 hr. S.boulardii grown under aerobic and microaerobic conditions and antagonized with overnight broth cultures of test bacterial isolates , The results revealed that aerobic cultures of yeast had more inhibito

Endothelin-1 (ET-1) is a potent vasoconstrictor hormone that has been identified as an important factor
responsible for the development of cardiovascular dysfunctions. ET-1 exerts its vasoconstrictor activity
through two pharmacologically distinct receptors, ETA and ETB that are found in vascular smooth muscle
cells (VSMCs) and the vasodilator activity through an ETB receptor located on endothelial cells. This study
aimed to show the impact of 1µM L-arginine (LA), 100µM tetrahydrobiopterin (BH4), and their combined
effect on ET-1 activity in both lead-treated and lead-untreated rat aortic rings. This means, investigating how
endothelial dysfunction reverses the role of nitric oxide precursor and cofa

Materials with external dimensions of one or more nanometers are referred to as nanomaterials. These structures result from a number of manufacturing processes. They are used in many industries, including pharmaceuticals, which is the most significant one. Numerous variables, including size, shape, surface morphology, crystallinity, solubility, etc., affect physical properties. While new physical and chemical processes are being created constantly, the biological method is the ideal strategy for synthesizing nanoparticles since it is straightforward, safe, and economical. Different kinds of nanoparticles can be metabolically synthesized by a wide variety of biological sources, including plants, bacteria, fungi, and yeast. There are

The letters are exposed in some texts of the classical Arabic language (poetry or prose), or in some of the Qur’anic texts, which are the main sources that were adopted on the day when provisions, rules and linguistic controls were established. I say that some of these letters are exposed in some contexts to deletion, mention, or change in the structure and shape of the letter. As for the omission, it is one of the aspects that distinguished Arabic, as well as other languages, for many purposes that differ among their user.
