من خلال ملاحظة الباحثتين الميدانية لمستوى الأداء الفني لمنتخب ناشئات القطر بالجمناستك لمهارة قفزة اليدين الأمامية على جهاز منصة القفز الحديثة لاحظن وجود مشكلة تكمن في ضعف هذا الأداء والذي يؤثر على بعض المتغيرات البيوكينماتيكية لهذه المهارة مما يؤدي إلى عدم أداء المهارة بالشكل الصحيح ، وتعزو الباحثتان ذلك الضعف إلى قلة الدفع بالرجلين والذراعين . لذا ارتأت الباحثتان إجراء هذا البحث الذي يهدف إلى تنمية القوة الانفجارية باستخدام تدريبات الأثقال بطريقة الصعود والهبوط للتعرف على تأثيرها في تحسين بعض المتغيرات البيوكينماتيكية والأداء الفني لمهارة البحث المختارة ، وكان من أهداف البحث التعرف على تأثير استخدام هذه التدريبات في تنمية القوة الانفجارية لدى اللاعبات ، وقد افترضت الباحثتان عدة فروض كان منها إن هنالك فروقاً ذات دلالة إحصائية بين نتائج التقويمين القبلي والبعدي نتيجة تنمية القوة الانفجارية باستخدام تدريبات الأثقال بطريقة الصعود والهبوط ولصالح التقويم البعدي ، وعليه كان المنهج المستخدم في البحث هو المنهج التجريبي وشملت عينة البحث لاعبات منتخب ناشئات القطر بالجمناستك بأعمار ( 10 – 12 سنة ) والبالغ عددهن ( 6 لاعبات ) ، وقد استغرق تطبيق المنهج التدريبي ( 3 أشهر ) بواقع ( 3 وحدات ) أسبوعياً أي بمجموع ( 36 ) وحدة تدريبية طوال مدة البحث ، وقد استنتجت الباحثتان عدة استنتاجات كان من أهمها أن التدريب بالأثقال بطريقة الصعود والهبوط يؤدي إلى تنمية القوة الانفجارية وان تنمية القوة الانفجارية يؤدي إلى تحسين بعض المتغيرات البيوكينماتيكية والأداء الفني لمهارة البحث المختارة .
Behavioral and emotional disorders represent one of the commonest problems facing children in particular and disturbing their parents and educators in general. This is because Iraqi people have long been living in difficult conditions and faced various terrorists’ operations, such as killing, destruction, robbery, and looting. Such operations are said to be one of the reasons that leads to the development of such disorders, and may negatively affect the psyche of the child and be reflected on his behavior as represented by playing with the IPad for hours, and suffering from nightmares. Accordingly, the current research aims to examine specifically the commonest negative behavioral disorders among kindergarten children during the post-t

Several characteristics of irradiated dental hard tissues have been considered advantageous, microscopically rough surfaces without demineralization, open dentinal tubules without smear layer production and dentin surface sterilization. The aim of this study is to determine and compare histology the microleakage in class V cavity restored with a light cured composite after conditioning the samples(tooth surface) with 1-acid etching, 2-Q-switched Nd:YAG Laser etching and finally 3- acid and laser etching. Materials and methods: Twenty four non carious human extracted teeth were used in this study. The samples were equally grouped into four groups of six teeth each.

Chitinase-3-like 1 protein (YKL-40) is a glycoprotein primarily produced in the arthritic joint and plays a crucial role in inflammatory processes. The aim of the study is to establish the role of YKL-40 as a biomarker for rheumatoid arthritis (RA) compared to proinflammatory biomarkers and disease activity. The study included 58 patients and 18 control. Diseases activity score (DAS-28) and clinical disease activity index (CDAI) were measured. Serum level of YKL-40, tumor necrosis factor-α (TNF-α), interleukin-1B (IL-1β), erythrocyte sedimentation (ESR), rheumatoid factor (RF), C-reactive protein (CRP), and anti-citrullinated protein antibody (ACPA) were assessed. The results showed that the median serum YKL-40 level which was 5.42
