Effect of Probiotics on The Relative Activity of Hyaluronidase and Streptokinase from Locally Isolated Streptococcus pyogenes

        This study aimed to investigate the inhibitory effect of probiotic microorganisms against Streptococcus pyogenes. A total of 85 pharyngeal swaps were collected from children infected with pharyngitis. Four isolates S. pyogenes were obtained and then evaluated for the activity of its spreading factors for infection streptokinase and hyaluronidase.

Effect of Wheat Germ Extracts on Some Biological Aspects: In vivo and In vitro Study

This project is aimed   to study the inhibition effect of wheat germ extract on some microorganisms, cancer cell line, and atopic dermatitis (eczema).The quantitative and qualitative detections of methanolic extract and methanol chloroform method extract by using gas chromatography–mass spectrometry (GC-MS) technique were achieved to detect the active groups.

Cytogenetic Study of Heat Stable Enterotoxin (a) Produced by Enterotoxigenic Escherichia coli on Colorectal Cancer Patients and Its Effect on Cancer Cells

       This study was conducted for investigating the effect of heat stable enterotoxin a (STa) produced by enterotoxigenic Escherichia coli on the proliferation of colorectal cancer cells. A total of (25) stool samples were collected from patients suffering from diarrhea to isolate E. coli strains that produce STa, and after performing microscopic examination, cultural characterization and biochemical identification only (11) isolates showed positive E. coli.

Effect of Abiotic Stress on The Accumulation of Some Metabolites in Ruta graveolens (In Vitro)

      Structural and functional characterization of environmental stress- induced genes has contributed to a better understanding of how plants respond and adapt to different abiotic stresses by using DDRT-PCR, with the aim of increasing salinity and drought tolerance in Ruta graveolens by employing plant tissue culture technique.

الاستجواب البرلماني وفق الدستور العراقي لعام 2005

تنص بعض النظم الدستورية على الرقابة المتبادلة بين السلطتين التشريعية والتنفيذية لتؤكد خضوع الهيئات الحاكمة للقواعد الدستورية ،ـ ولتكفل إلى حد كبير عدم طغيان أحدى السلطتين على الأخرى ، وعدم تجأوز أحدهما الوظيفة التي أسندها اليها المشرع الدستوري الى وظيفة أخرى ، وتظهر هذه الرقابة عادة في النظم الدستورية التي تأخذ بالنظام البرلماني ، فالقواعد الدستورية في النظم البرلمانية تقرر للسلطة التشريعية حقوقا معينة تمارسها في مواجهة الحكومة ، وتتحقق باستعمالها رقابتها الفعالة على أعمال السلطة التنفيذية وتصرفاتها ، وفي مقابل هذه الحقوق التي يضعها المشرع الدستوري تحت

Production, purification and characterization of protease produced from Cronobacter sakazakii

      In this study, five isolates of Cronobacter sakazakii  were obtained from biotechnology department, college of science, of AL-Nahrain university, primarily identified according to their cultural , morphological characteristics and biochemical tests. The ability of these isolates in protease production was examined. Results showed that all five isolates of C.sakazakii were protease producers with variable degrees. Among them, the isolate symbold  C.sakazakii R4 was the most efficient in protease production.

Effect of Static Magnetic Field on Aflatoxin Production by Aspergillus flavus under Solid State Fermentation

    The fungus Aspergillus flavus was exposed to the north pole of the magnetic field and then compared its effect with the control treatment (without the magnetic field energy). The substrates used for the growth of A. flavus  (corn, wheat, rice and wheat flour) were obtained from the local market and sterilized by autoclaving. A  static magnetic field of 100 gauss was subjected to the A. flavus for (7, 14
