حظيت السمية الخلوية للمستخلصات النباتية باهتمام كبير في السنوات الأخيرة لتقييم نشاطها ضد الأورام. تركز الوقاية الكيميائية من السرطان على السمية الخلوية للمستخلصات النباتية لتكون سامة تجاه خطوط الخلايا السرطانية دون أن تؤثر على الخلايا الطبيعية. الهدف من هذه الدراسة هو تقييم السمية الخلوية لمستخلصي الزنجبيل و أوراق الزيتون ومزيجهما بنسبة 1: 1 تجاه خطوط خلايا RD وتقدير فعالية هذه المسخلصات ضد الاجهاد التاكسدي بدلالة SOD و MDA. تم الحصول على المستخلصات الكحولية لكل من الزنجبيل وأوراق الزيتون بطريقة السوكسيلت. وحضر المستخلص الثالث بخلط كميات متساوية من مستخلص أوراق الزيتون والزنجبيل بنسبة 1: 1. تم تحضير اطباق من خطوط الخلايا RD وخطوط الخلايا الاعتيادية وتم اختبار تراكيز مختلفة من المستخلصات المحضرة (12.5 - 800 ميكروغرام / مل) لتسجيل فعالياتهم تجاه كل من RD وخطوط الخلايا الطبيعية. . كذلك ، تم تقدير مستوى انزيم SOD و MDA اعتمادًا على طرائق العمل الخاصة بهما. اظهرت النتائج وجود فرق معنوي بين السمية الخلوية للتراكيز المدروسة لكل مستخلص تجاه خطوط الخلايا RD، اذ انخفضت قابلية بقاء خطوط الخلايا RD مع زيادة تراكيز المستخلصات ، وفي نفس الوقت لم تؤثر تلك المستخلصات على خطوط الخلايا الطبيعية. كذلك بينت النتائج ازدياد مستويات SOD مع زيادة تركيز المستخلص على عكس مستويات MDA التي انخفضت مع زيادة تراكيز المستخلص. يمكن الاستنتاج بان نشاط المستخلصات المحضرة تجاه خطوط الخلايا RD دون التأثير على خطوط الخلايا الطبيعية يعزز مبادئ المنع الكيميائي للسرطان ، إلى جانب الخصائص المضادة للأكسدة التي يمكن أن تقلل من الإجهاد التأكسدي الذي يصاحب الخلايا السرطانية وتنشيط العوامل الطبيعية المضادة للاكسدة في جسم الانسان.
Background: Cardiopulmonary resuscitation (CPR) is a technique or procedure that combined chest compression and rescue breathing to maintain enough circulation that prevents brain damage until other essential steps are taken to control the main cause of cardiac and respiratory arrest. The health care personnel should be qualified in the performing of cardiopulmonary resuscitation (CPR) to improve the survival rate of the victims. Therefore; it is necessary to use new methods for learning [1]. Objectives: the study aims to compare the effectiveness of self-instructional teaching strategy and traditional teaching approach on student’s knowledge toward cardiopulmonary resuscitation. Methods: A randomized comparative trial (RCT) design was ca

Show MoreThe main purpose of the research is to diagnose the importance of the role that strategic memory plays with its three variables (content, structure, and processes) in helping the human resource department to use the COSO model with its five components (culture and governance, strategy and objectives, performance, communications and information, and feedback) in auditing activities and tasks Her own. As the research problem emphasized the existence of a lack of cognitive perception, of the importance of strategic memory, and the investment of its components in the rationalization of the application of the COSO model. and therefore it can be emphasized that the importance of the research is to provide treatments for problems relate

It can inhibit insulin receptor, enhance insulin sensitivity and make the individuals more likely to develop type 2 diabetes, then disorder in lipid profile (Total cholesterol(TC), low density lipoprotein cholesterol (LDL-c), high density lipoprotein cholesterol (HDL-c), Triglyceride(TG) and very low density lipoprotein cholesterol (VLDL-c) . To evaluate Fetuin-A, total protein, albumin, globulin, HbAlc and lipid profile in 200 adult and elderly Iraqi patients with type 2 Diabetes Mellitus were taken and compare them with 200 subjects as a healthy control. The laboratory analysis(for patients and

Efficiency of Pisum sativum plants in using tricalcium super phosphate (TSP) in presence and absence of mycorrhizal fungi was evaluated in the field experiment in College of Science / Al-Mustansiriyah University. The experiment comprised of (6) treatments prepared from the interaction of two levels of inoculation [non-inoculation with fungus F0 and inoculation with Glomus mosseae fungus (F1)]. And three levels of phosphorus: 0,20,40 Kg P/ha. The experimental size was (1x2)m. Irrigation and hand-weeding were done when needed. The following plant measurements were recorded: (Shoots dry weight, concentration of N and P% in addition to percentage of root infection with mycorrhizal fungi at flowering 50% of plants. The re

Show MoreThe environmental contamination by the polycyclic aromatic hydrocarbons (PAHs) and heavy metals (Pb, Cu, Ni, Cr, and Cd) concentrations in the leaves of plant Eucalyptus camaldulensis were determined at the city of Kirkuk in 15 selected locations using GPS. The pickings up of samples were carried out in two periods October 2010 and March 2011. Compared with results of other studies, the concentration levels of determined heavy metals show values within these studies results. The average total concentration of polycyclic aromatic hydrocarbons (PAHs) in the leaves of Plant Eucalyptus camaldulensis indicated 37.1 ppb in October, while in March 165.2 ppb.

Agrobacterium is one plant genetic engineering tool that integrates genes of interest inside a host plant. In recent years, the need to produce recombinant proteins as therapeutics has growing rapidly, and human glucocerebrosidase is one of the proteins that is need to treat disease. In this study, specific primers were designed to amplify Hu-GBA1 gene from constructed pGEM-GBA plasmid which was cloned into the plant expression vector pCAMBIA1304. The generated recombinant pCAMBIA1304-GBA plasmid was used to transform A. tumefaciens LBA4404
