جرثومة الزائفة الزنجارية كاشف فعال للتحري عن المستخلصات النباتية المثبطة لاستشعار النصاب
...Show More Authors

استشعار النصاب (Quorum sensing, QS) هو آلية معروفة تستخدمها جراثيم عديدة للسيطرة على عوامل الضراوة الهامة من خلال الإنتاج والاستجابة اللاحقة ل .)N-acylhomoserine (AHLs جرى تسجيل تثبيط استشعار النصاب (QSI) ، الذي يستهدف الإشارات المعتمدة على AHL، كاستراتيجية للسيطرة على الأمراضية الجرثومية. وبالتالي، تهدف هذه الدراسة إلى البحث عن قدرة جرثومة الزائفة الزنجارية كمؤشر للفحص السريع عن QSI المحتمل المتسبب عن المستخلصات النباتية على أساس تثبيط الصبغة. استخدمت أربع مستخلصات نباتية كحولية بضمنها: براعم زهور القرنفل المجففة ( Syzygium aromaticum L)، لحاء القرفة (Cinnamomum cassia L)، أوراق المورينجا (Moringa oleifera Lam)، والقطب (Tribulus terrestris L) وجرى مقارنة قابيلتها على التثبيط QSI)) مع الفيورانون. استخدمت طريقة الانتشار في حفر الهلام، إذ جري تلقيح عزلة الزائفة الزنجارية على وسط الهلام الخاص بـها الذي احتوى على حفر بحجم 8 ملم لتحميل تراكيز مختلفة من المستخلصات النباتية فضلا عن الفيورانون أو محلول الفوسفات الداريء (سيطرة سالبة). أظهرت النتائج نجاح الفيورانون في تثبيط صبغة البايوسيانين للزوائف الزنجارية دون التداخل مع النمو الجرثومي، وهذا يؤكد قدرة هذه العزلة الجرثومية كمؤشر فعال يستدل من خلاله على وجود QS. الأهم من ذلك، سبب مستخلص القرنفل بتراكيز مختلفة في تثبيط تام لصبغة البايوسيانين مع تأثير ضئيل على النمو الجرثومي. عند استخدام القرفة، أظهرت التراكيز العالية فقط تثبي ًطا واض ًحا لصبغة العزلة المستخدمة. تسببت المورينغا أي ًضا في درجة معينة من تثبيط الصبغة ولكن بتراكيز عالية فقط. وعلى العكس من ذلك، لم يؤثر القطب على إنتاج البيوسيانين ولا على الحيوية الجرثومية. يستنتج من هذه الدراسة نجاح عزلة الزائفة الزنجارية المنتجة للبايوسيانين في فحص مثبطات QS. توصي هذه الدراسة البسيطة باستخدام مثل هذه العزلة ككاشف عن QSI دون الاعتماد على استيراد سلالات معينة من جراثيم Chromobacterium violaceum أو Pseudomonas aureofaciens أو Agrobacterium tumefaciens.

Detection of Cd69 Marker by Flow Cytometry in Iraqi Patients with Coeliac Disease.
...Show More Authors

Background: Coeliac disease is a chronic, immunologically determined form of enteropathy affecting the small intestine in genetically predisposed children and adults. It is precipitated by the ingestion of gluten-containing foods. It is also referred to as celiac sprue, gluten-sensitive enteropathy, or nontropical sprue. CD69 is a lymphoid activation antigen whose rapid expression makes it suitable for the detection of T-ce

An Adaptive Harmony Search Part-of-Speech tagger for Square Hmong Corpus
...Show More Authors

Data-driven models perform poorly on part-of-speech tagging problems with the square Hmong language, a low-resource corpus. This paper designs a weight evaluation function to reduce the influence of unknown words. It proposes an improved harmony search algorithm utilizing the roulette and local evaluation strategies for handling the square Hmong part-of-speech tagging problem. The experiment shows that the average accuracy of the proposed model is 6%, 8% more than HMM and BiLSTM-CRF models, respectively. Meanwhile, the average F1 of the proposed model is also 6%, 3% more than HMM and BiLSTM-CRF models, respectively.

Use of Remote Sensing in the assessment and classification of land degradation in the district of Mahmudiya for the period 1990-2007
...Show More Authors

The study consisted in the development and use of a practical method to detect and
monitor, analyze and produce maps of changes in land use and land cover in the district of
Mahmudiya in Baghdad during the period 1990-2007 using the applications of remote sensing
techniques and with the assisstant of geographic information systems (GIS),as a valuable
contribution to land degradation studies.
This study is based maiuly on the processing on two subsets of landsat5 TM images picked up
in August 1990 and 2007 respectively in order to facilitate comparision and were thengeometrically and radiometrcally calibrated ,to used for digital classification purposes using
maximum liklihoods classification or six spectral bands of

Abstract:                                        

   We can notice cluster data in social, health and behavioral sciences, so this type of data have a link between its observations and we can express these clusters through the relationship between measurements on units within the same group.

    In this research, I estimate the reliability function of cluster function by using the seemingly unrelate

Predict the Laser Power and Recovery Period in Treatment by Endovenous Laser Ablation (EVLA)
...Show More Authors

            Eight patients (3 male and 5 female) were treated in this study by Endovenous Laser Ablation (EVLA); Mathematical models are proposed to estimate the applied laser power and to assess the recovery period. The estimations of the applied laser power and recovery period in these models will be depended mainly on the diameter of the incompetent vein.  In addition, Excel Program was utilized to find the proposed models.  A 1470 nm diode laser up to 15W continuous power (CW) was used in the treatment of venous ulcers by EVLA procedure. Following up by duplex ultrasound was started in the 1st week after the first session until the vein is completely closed. The present study concluded that the relationship both between
