           To Investigate the ability of Streptomyces isolate to produce hygromycin B antibiotic as antithelmantic agent in poultry feed and selecting a suitable expression vector encoded hygromycin B phosphotransferase resistance gene and transforming Lactobacillus isolateby electroporation , from a total of 53 Streptomyces isolates, DNA was extracted and screened for the presence of hygomycin B gene using specific designed primer sets in Polymerase Chain Reaction (PCR) technique.  Only three of the isolates were positive for the existence of such a gene which

Mutations in NPM1 gene ranked within the most frequent known genetic marker in AML. In order to detect the frequency of NPM1 mutations within the region of exon 2 and exon 3 in Iraqi AML patients using conventional polymerized chain reaction technique, the region from 2380 bp to 4140 bp of NPM1 gene,which represents the region flanking both exon 2 and 3, was amplified by using two specific primers in a thermal cycler. Results showed that the concentration of genomic DNA after extraction was ranged between (52-93) µg/ml with purity of (1.8-1.92).

     The present study was designed to detect the effect of Saussurea lappa and Cyperus esculentus extracts on male albino mice fertility in addition to the histopathological changes in liver, kidney and testes. Saussurea lappa extract was prepared by maceration of 50 gm of Saussurea lappa roots with 90% methanol, then chemical detection of flavonoids, alkaloids, tannins, saponins, terpenes and steroids was carried out.

الجريمة ظاهرة اجتماعية لها جوانب مادية ندركها بحواسنا ونشعر بها من خلال ما تحدثه من خلل وارباك في أوضاع الجماعة وفي النظم العامة التي تحدد سير الحياة المجتمعية، وما يترتب على ذلك من اضرار اقتصادية وسياسية وثقافية تؤدي الى تأخر تقدم المجتمع، وتحول بينه ويبن التطور اللازم لنمو طاقاته المختلفة.ومرتكب هذه الجريمة انسان دفعته عوامل عدة لارتكابها، منها داخلية واخرى خارجية، تظافرت وامتزجت وتفاعلت في انتاج هذا السلوك المؤدي الى ارتكاب الجريمة، وهنا يبرز الجانب المعنوي الذي يتمثل في الدوافع الداخلية لدى مرتكب الجريمة حيث تعتبر الارادة الآثمة المظهر الرئيس له.
