APR-246 enhances the anticancer effect of doxorubicin against p53-mutant AsPC-1 pancreatic cancer cells
...Show More Authors

سرطان البنكرياس هو مرض ذو معدل وفيات مرتفع، ولا يزال التشخيص المبكر لسرطان البنكرياس يمثل تحديًا. يظل معدل البقاء النسبي لمدة 5 سنوات أقل من 8%، والاستراتيجيات العلاجية غير فعالة في زيادة معدلات بقاء المريض على قيد الحياة. في خلايا سرطان البنكرياس، ارتبطت مقاومة العلاج بالتغيرات الجينية التي تؤدي إلى ظهور مسارات خلوية شاذة؛ ولذلك، هناك ما يبرر ايجاد استراتيجيات جديدة لعلاج هذا المرض. هنا، سعينا لاستكشاف مُنشط p53، APR-246، إما كدواء أحادي أو مدمج مع دوكسوروبيسين في خط خلايا AsPC-1  ذات بروتين p53 المتحول  (p53-mut). تمت دراسة السمية الخلوية لـدوائي APR-246 ودوكوروبيسين اما منفردة أو مجتمعة في خط خلايا AsPC-1 مع اختبار MTT. تم حساب مؤشر معامل قياس التأزر (Combination Index) بناءً على نهج Chou و Talalay باستخدام برنامج CalcuSyn. تم تقييم موت الخلايا المبرمج بعد تصبيغها باستخداممادة الاكريدين اورنج/ايثيديوم برومايد (AO/EB).  تم فحص التغيرات المورفولوجية تحت المجهر المقلوب بقوة تكبير 200 مرة  تم قياس كمية التعبير الجيني باستخدام فحص النسخ العكسي الكمي PCR  . أظهر APR-246 وحده تأثيرات متواضعة مضادة للتكاثر، في حين أظهر دوكسوروبيسين مع APR-246 تأثيرات تآزرية مرتبطة بالتغير المورفولوجي؛ لم يلاحظ أزدياد في نسبة موت الخلايا المبرمج في الخلايا المعاملة بكلا العقارين و هذا ما اكدته مستويات جين ال NOXA. في الختام، APR-246، سواء كان العلاج وحيدًا أو مقترنًا بـدوكسوروبيسين، كان يعيق تكاثر خلايا AsPC-1  ذات p53-mut، وهناك ما يبرر إجراء المزيد من الأبحاث في المختبر وفي الجسم الحي.

The Effect of Internal Marketing on Organizational Citizenship Behavior
...Show More Authors

The aim of this paper is to determine the effect of internal marketing through three dimensions: vision, development, and reward - on organizational citizenship behavior in three private universities in Iraq. Organizations’ view of their members as internal customers could be made them more realistic in dealing with the reasons for leaving and going to other organizations. This can promote business organizations to build an organizational environment that contributes to making the organization look like the homeland of those workers. The research method is descriptive and analytical. The tool for data collection was the questionnaire. Statistical software (SPSS V.23 and AMOS V.23) was used to analyze the data. The research sample was r

The Effect of Services system in Architectural form developments
...Show More Authors

Architecture forms theoretical summaries and multi systems that have the essence of change, and that what distinguishes Architecture from other sciences and their systems. Architecture means way of life via its expressional products and that appears through its systems. These systems are based on formative and technological properties in form, structure, services and materials as well as
their moral forms. All these are associated with techniques and facilities in order to establish integrated system.
Architectural creation does not come from void but it depends on a conception base to create a new condition for creative architectural product. The general problem of the research concentrated on limited theoretical and practica

The Effect of Chronic Renal Failure on Thyroid Hormones
...Show More Authors

       Chronic renal failure (CRF) affects thyroid function in multiple ways, including low circulating thyroid hormone concentration, altered peripheral hormone metabolism, disturbed binding to carrier proteins, possible reduction in tissue thyroid hormone content, and increased iodine store in thyroid glands.The target of study is to find a relationship between chronic renal failure and thyroid function.In addition, we tried to study the effect of CRF on serum creatinine dependent on the level of thyroid hormones (T3 and T4) and thyroid stimulating hormones(TSH). Forty patients with chronic renal failure (20 male, 20 female) were enrolled in this study in addition to forty healthy individual as control gro

The Effect of Grain Boundaries on Schottky Diode Parameters
...Show More Authors

The activation energy and optical band gap of different regions (p-type) polysilicon have been measured. Both microscopic studies and current-voltage characteristics of diodes prepared on different surface regions were carried out. Comparison of diodes parameters and microscopic studies indicate that the type of angles between boundaries has a significant effect on diodes parameters while the boundary lengths per unit area has less effect. The mechanism of Al-interaction with grain boundaries and their intersecting points at different temperature were also studies. The X-ray fluorescence spectrometry has been used for detection of diffused A1%.

The effect of silver nanoparticles on braf gene expression
...Show More Authors

The recent studies suggested the possible toxicities or genetic alterations associated with biological and medical applications of silver nanoparticles (AgNPs). The current research is directed to see if AgNPs administration can lead to some changes in expression of BRAF gene in selected body organs tissues. Fifty-six male of musmusculs (Balb/C) mice from the animal house of Al-Nahrain Centre of Biotechnology were used. These animals were divided randomly to seven groups (eight mouse in each group), one of these groups represented the control group, three groups were subjected to different doses of AgNPs (0.25, 0.5and 1 mg/kg of body weight) for one week, and the remaining three groups were subjected to three different doses of AgNP
