الخلفية: العقدية المقيحة المعروفة أيضًا باسم ""(GAS) هي احدى مسببات الأمراض ذات الأهمية الصحية العامة، حيث تصيب 18.1 مليون شخص في جميع أنحاء العالم وتقتل 500000 شخص كل عام. الهدف: حددت هذه المراجعة المقالات المنشورة حول عوامل الخطر واستراتيجيات الوقاية والسيطرة لأمراض المكورات العقدية. المواد والأساليب: تم إجراء بحث منهجي لتحديد الأوراق المنشورة على قواعد البيانات الإلكترونية Web of Science و PubMed و Scopus و Google Scholar في محاولة لتوفير معلومات أساسية حول عدوى Streptococcus ، والمخاطر المحتملة لانتشارها ، واستراتيجيات العلاج والوقاية . النتائج: الطرق الأكثر شيوعًا لانتقال العقديه القيحيه هي من خلال الرذاذ التنفسي ، الآفات الجلدية التي تسببها العقديه القيحيه ملامسة الأشياء أو الأجهزة المصابة. هناك طريقة أخرى محتملة وهي انتقال العدوى عن طريق الغذاء ولكن هناك حاجة إلى مزيد من البحث لتحديد مسار العدوى هذا. تم العثور على المجتمعات الأصلية ، وتلك ذات الوضع الاجتماعي والاقتصادي المنخفض في جميع أنحاء العالم معرضة بشكل خاص لأمراض المكورات العقدية ، وكذلك الأطفال وكبار السن والذين يعانون من ضعف في جهاز المناعة. هذه المجموعات معرضة للإصابة بعدوى العقديه القيحيه ومضاعفاتها مع ارتفاع معدلات العدوى في المؤسسات التعليمية والمستشفيات والازدحام والزيادة المستمرة في الاتصال الاجتماعي. أهمية تحسين الظروف المعيشية والنظافة الشخصية واليدين هي إحدى التقنيات للوقاية من عدوى العقديه القيحيه مع التركيز على طرق مكافحة العدوى بدقة أكبر. الاستنتاج: يجب أن تستهدف تدابير المنع والمكافحةللعدوى بالعقديه القيحيه مع تحسين الظروف المعيشية والنظافة الشخصية غسل اليدين باستمرار ايضا يجب التأكيد على الالتزام بممارسات الوقاية من العدوى ومكافحتها في الاشخاص الذين يملكون ظروف مريضيه عالية الخطورة .
This research focuses on the contemporary geostrategic transformations that afflicted the countries of the Middle East, with a focus on the countries of the Arab East, after the collapse of the system of international relations, and the emergence of the unipolar system led by the United States of America. After the events of September 11 and the events that followed, especially the occupation of Iraq in 2003, the study area witnessed a group of geopolitical variables and the emergence of dangerous phenomena that threatened the state structure in the countries of the Middle East; the most notably are the phenomenon of terrorism, cross-border armed groups, sectarian polarization, the phenomenon of migration and the internal and the externa

Show MoreIn this work a novel drug delivery system through modification of poly acrylic acid with Methionine as a spacer between the poly acrylic acid which was converted to its acyl chloride and reacted with Methionine as spacer unit which has been reacted with Ampicillin drug. In vitro drug release study had been conducted successfully in basic medium in pH 7.4 and acidic medium in pH 1.1 at 37?. Due to many problems associated with drug release and, this modification could decrease the side effect of drug. The prepared prodrug polymer was characterized by spectra method [FTIR and 1H?NMR]. Physical properties and intrinsic viscosity of drug polymer were determined. The good results were obtained in the presence of spacer unit with compar

Characterized the Middle East has geographic, economic, and geostrategic peculiarities, but it suffers from many problems, such as disagreement over what it means as a concept, or what it represents of a geographic extension. The question is related to the ambiguity surrounding the concept of the Middle East? The purpose of its launch? As it relates to its geostrategic, economic, and geo-cultural importance? And manifestations of this importance? And to what extent he retained his value in the strategies of the major powers? Research hypotheses:
-The multiplicity of concepts for the Middle East region, with international political and Geostrategic interests.- The geostrategic value of the Middle East has made it a focal point for
... Show MoreChaotic systems have been proved to be useful and effective for cryptography. Through this work, a new Feistel cipher depend upon chaos systems and Feistel network structure with dynamic secret key size according to the message size have been proposed. Compared with the classical traditional ciphers like Feistel-based structure ciphers, Data Encryption Standards (DES), is the common example of Feistel-based ciphers, the process of confusion and diffusion, will contains the dynamical permutation choice boxes, dynamical substitution choice boxes, which will be generated once and hence, considered static,
While using chaotic maps, in the suggested system, called
Biometrics is widely used with security systems nowadays; each biometric modality can be useful and has distinctive properties that provide uniqueness and ambiguity for security systems especially in communication and network technologies. This paper is about using biometric features of fingerprint, which is called (minutiae) to cipher a text message and ensure safe arrival of data at receiver end. The classical cryptosystems (Caesar, Vigenère, etc.) became obsolete methods for encryption because of the high-performance machines which focusing on repetition of the key in their attacks to break the cipher. Several Researchers of cryptography give efforts to modify and develop Vigenère cipher by enhancing its weaknesses.
