Preparing a Compound of New Nanoparticles of Lactam, PE to Improve Their Specifications
...Show More Authors

يدور هذا البحث حول خواص البولي ايثيلين (PE) باستخدام اللاكتام مع مركبات أكسيد النانو المعدنية المستخرجة من نبات (القرنفل) وهي براعم زهرة شجرة القرنفل كمثبت وعامل اختزال . حيث يستقر أكسيد النانو ويغطي البوليمر الطبيعي. الهدف من الدراسة هو أن أكسيد النانو يؤدي أفضل ترابط للمركبات المحضرة ، بسبب زيادة مساحة السطح ، وبالتالي القدرة على الارتباط بالبوليمر المحضر. والقدرة على الثبات الإلكتروني بسبب كثرة الروابط مما يسمح بتوزيع الشحنة الإلكترونية ثم تشتيتها خارج سطح البوليمر مما يحسن من خواص البوليمر ويجعله مادة صديقة للبيئة يسهل استخدامها تقنية مرتبطة بالصب. بحيث لا يضر بصحة الإنسان والكائنات الحية الأخرى. خلصت الدراسة إلى أنه تم تحضير جزيئات أكسيد الزنك النانوية من مصادر نباتية طبيعية ذات منتج عالي لاستخدامها كمحفز لتحضير المونومرات المهمة صناعياً ، كما تمت إضافة بوليمر لاكتام في وجود أكسيد الزنك المستخرج من النباتات (القرنفل). بوليمر اصطناعي يتحلل عندما يستهلكه الإنسان. تم تمييز جزيئات الأكسيد النانوية والمونومرات والبوليمرات باستخدام طرق التحليل الطيفي. وأشار تحليل FTIR و TGA وباستعمال حيود الأشعة السينية (XRD) والمسح المجهري الإلكتروني (SEM) والفحص المجهري للقوة الذرية، أن البوليمر الناتج عبارة عن مادة متجانسة ذات وزن جزيئي مرتفع مطعمة بمقاييس نانوية عالية الجودة.

Designing of Human Serum Albumin Nanoparticles for Drug Delivery: a Potential Use of Anticancer Treatment
...Show More Authors

Human serum albumin (HSA) nanoparticles have been widely used as versatile drug delivery systems for improving the efficiency and pharmaceutical properties of drugs. The present study aimed to design HSA nanoparticle encapsulated with the hydrophobic anticancer pyridine derivative (2-((2-([1,1'-biphenyl]-4-yl)imidazo[1,2-a]pyrimidin-3-yl)methylene)hydrazine-1-carbothioamide (BIPHC)). The synthesis of HSA-BIPHC nanoparticles was achieved using a desolvation process. Atomic force microscopy (AFM) analysis showed the average size of HSA-BIPHC nanoparticles was 80.21 nm. The percentages of entrapment efficacy, loading capacity and production yield were 98.11%, 9.77% and 91.29%, respectively. An In vitro release study revealed that HSA-BIPHC nan

Summary

   

 Praise be to God, Lord of the Worlds, and prayers and peace be upon the Master of the Messengers, Muhammad, and upon all his family and companions.

      The circle of taboos in the Jewish Sharia is wider than other laws, as the Jews have severe and very complicated rituals in the matter of food, which may not be found among other people of other religions, as the dietary laws that specify foods and drinks forbidden in the Jewish Sharia include very diverse topics.  The Torah specified all these laws with several texts

Abstract

To evaluate the effectiveness of Phenolic Compound of Salvia Frigida on induced atopic dermatitis (AD) of mice. Forty mice were included in the study, divided in to four groups (10 mice/group): apparently healthy, induced AD without treatment, induced AD treated with tacrolimus 0.1% ointment, and induced AD treated with Phenolic Compound of Salvia Frigida cream 5%. Examination of histopathology was done and skin homogenates levels also measured. Levels of WBC, Eosinophil, skin tissue homogenate of IL-13 and IL-4, serum IgE, and histopathological scores were significantly increased among induced non treated AD group in comparison with control group.
