1-Objective:- Polyphenols are biochemical compounds with antioxidant activity against differences diseases related to Lipid peroxidation such as diabetes mellitus. Polyphenols distributed widely in medical plants, the aim of the study is to extract and analyze some polyphenolic compounds from grape seeds and examine their effects on (STZ) induced diabetic mice. 2-Methods:- In the present study , a group of polyphenols has been extracted from Iraqi grape seeds by ethanol and the extract has been analyzed by using High Performance Liquid Chromatography (HPLC) coupled to ultra violet (UV) detection. Five fractions were eluted from the column : procyanidin B1, gallic acid , quercetin , catechin and epicatechin. The detection was recorded at (280 nm). The reactive action of the above polyphenols on glucose, and malondialdehyde (MDA) levels and glutathione – S – transferase (GST) activity was tested in (30) streptozotocin (STZ) induced diabetic mice which treated with extracted grape seeds polyphenols to examine the antioxidant effect of these compounds . Grape seeds polyphenols action on the above parameters was determined before treatment and after (1 week), ( 2 weeks) and (3 weeks) of treatment with this reactive extract. 3-Results:- The data have shown that glucose levels were increased in (30) diabetic mice (after injection with streptozotocin) compared with control group (p<0.001) but after treatment with grape seeds polyphenols , glucose levels were decreased relatively (p<0.001) after (1 week), (p<0.001) after (2 weeks) and (p<0.01) after (3 weeks) of treatment with these polyphenolic compounds. MDA levels were increased for diabetic mice (after injection with streptozotocin) compared with control group (p<0.001) but after treatment with grape seeds polyphenols , MDA levels were decreased relatively (p<0.01) after (1 week) ,(p<0.01) after (2 weeks) and (p<0.05) after (3 weeks) of treatment. GST activity was increased in diabetic mice (after injection with streptozotocin ) compared with control group (p<0.001) but after treatment with grape seeds polyphenols , GST activity was decreased relatively (p<0.01) after (1 week), (p<0.01) after (2 weeks) an (p<0.05) after (3 weeks)of treatment with these antioxidant compounds. 4-Conclusion:- Our data indicated that glucose , MDA levels and GST activity correlated positively with oxidative stress related to diabetes mellitus.
This study research to Showing The impact of the integration process on the quality of Insurance service and analyze the impact financially to determine whether there is any impact on the quality of the insurance service, in addition to identifying the obstacles that impede the merger between the insurance companies, insurance and the appropriate proposals for its' application and benefit from the benefits achieved.
The importance of The study lies in the fact that it is an important and vital spotlight that is becoming increasingly important in the world to confront the various difficulties and crises that have occurred recently in light of the liberalization of international trade, globalization a

Latent heat energy storage (LHES) is one of the suitable solutions for this problem. LHES becomes a basic element in renewable energy systems. LHES compensate for the energy lack when these systems are at low production conditions. The present work considered a shell and tube LHES for numerical investigation of the tube rotation influence on the melting process. The simulation and calculations were carried out using ANSYS Fluent software. Paraffin wax represents the phase change material (PCM) in this work, while water was selected to be the heat transfer fluid (HTF). The calculations were carried o

The research problem is summarized in the main question: How does satire featured in television programs influence the portrayal of Iraqi politicians? This research adopts a descriptive approach and employs a survey methodology. The primary data collection tool is a questionnaire, complemented by observation and measurement techniques. The study draws upon the framework of cultural cultivation theory as a guiding theoretical foundation. A total of 430 questionnaires were disseminated among respondents who regularly watch satirical programs, selected through a multi-stage random sampling procedure.

This research aims to conduct a linguistic analysis of the translation of the novel "The Corpse Washer" by the Iraqi author Sinan Antoon. The main objective is to explore the challenges and strategies involved in translating this literary work, particularly the difficulties in translating the Baghdadi dialect and the obstacles it poses for non-native speakers. Employing a descriptive research methodology, the study examines the linguistic aspects of the translation, specifically selected conversational texts in the novel. It identifies the difficulties faced by translators in preserving the essence of the original novel and presents instances where errors occurred in translating vocabulary, conversational expressions, proverbs, and idi

This study aimed to test the effect of different concentrations of cardamom and black tea extracts on the sensitivity and growth of salivary mutans streptococci in comparison to chlorhexidine gluconate (0.2%) in vitro. Materials and methods: In this study. Mutans streptococci were isolated from saliva of 34 healthy people (aged between 22-40yrs). The bacteria was isolated, purifiedand diagnosed according to morphologicalcharacteristic and biochemical tests. Aqueous extracts of cardamom and black tea were prepared.
