يعد تحليل العلاقات الكمية بين البنية والممتلكات/النشاط (QSPR/QSAR) أمرًا بالغ الأهمية لفهم خصائص المركبات المرتبطة بالمخدرات، خاصة في علاج مرض الزهايمر. في هذه الدراسة، هدفنا هو استخدام أساليب مبتكرة بما في ذلك استخدام المؤشرات الطوبولوجية -درجة و- درجة ، المستمدة من نظرية الرسم البياني، لتقييم الخصائص والخصائص الفيزيائية والكيميائية لخمسة أدوية لمرض الزهايمر: تاكرين، دونيبيزيل، ريفيستيجمين، جالانتامين و والهوبرزين أ . تقدم هذه المؤشرات الطوبولوجية طريقة جديدة لالتقاط المعلومات الهيكلية الجزيئية الأساسية، مما يقلل من عدد الواصفات مع تعزيز ارتباطها بالخصائص الجزيئية المتنوعة. ومن خلال الحسابات الشاملة لهذه المؤشرات، هدفنا هو توضيح الخصائص الجزيئية المعقدة لأدوية مرض الزهايمر. علاوة على ذلك، أجرينا تحليلات QSPR وQSAR لربط المؤشرات الطوبولوجية المحسوبة بالخصائص الفيزيائية والكيميائية المختلفة للأدوية. في حين أن الأساليب المبتكرة المستخدمة في دراستنا توفر رؤى قيمة. لا تساهم النتائج التي توصلنا إليها في تعزيز فهمنا لخصائص أدوية مرض الزهايمر فحسب، بل تحمل أيضًا آثارًا على تطوير الأدوية وتحسينها في إدارة مرض الزهايمر. ومن خلال تعزيز معرفتنا بخصائص هذه المركبات، فإن هدفنا هو معالجة الطبيعة المتعددة العوامل لمرض الزهايمر وتحسين التدخلات العلاجية.
The study was conducted to determine the effect Toxoplasma gondii and the efficacy of azithromycin and garlic tablets on the treatment of acute murine toxoplasmosis and observe the histopathological changes due to infection. 60 Albino mice were divided into six groups, and their survival rate, pathology, bioassay trial and immunofluorescence were observed. Results revealed that azithromycin (250 mg/kg/day) given to infected mice increased the survival rate (90% on day 7 PI) and decreased the histopathological changes when compared with the control groups. Garlic tablets (500 mg/kg/day) had lesser effect on infected mice, and the survival rate (40% at days 6 and 7 PI) was lower than the groups treated with azithromycin. The group treated wit

For analyzing the dynamical behavior of cholera disease, a fractional-order model was developed. First, the positivity and boundedness of the system's solutions were established. The local stability of the equilibrium points was also analyzed. Second, a Lyapunov function was used to construct the global asymptotic stability of the system for both endemic and disease-free equilibrium points. Finally, numerical simulations and sensitivity analysis were carried out using matlab software to demonstrate the accuracy and validate the obtained results.
Background: human paillomavirus infections (genital warts) are the most frequent sexually transmitted viral infections. a wide range of treatment options is available with different efficacy.
Objective: To evaluate the efficacy of podophyllin, trichloracetic acid (TCA) in the treatment of genital warts and side effects of them.
Subjects and methods: a total of sixty patients with genital warts were randomly selected, 30 in each group, in the Department of Dermatology, medical city for a Duration of 11 months from January 2009 to December 2009 treated with 35 % podophyllin in the tincture of benzoin or 50% TCA) .Forty-eight patients were followed up for three months.

Background and purpose: Animal model helps researchers to evaluate new treatment plan for human and understand pathological mechanism involved in a development of disease. The use of rats as an animal model for Alzheimer's research has become a favorite among researchers. Rats are capable in mimicking Alzheimer disease due to their intelligence and quick adaptation to nature. At present there are several methods that can be used to induce Alzheimer's animals, but each method has advantages and disadvantages. We need to learn other methods that can provide many advantages and few disadvantages. The Amyloid-beta 42 (Aβ-42) and Reactive Oxygen Species (ROS) are thought to play an important role in the pathology of Alzheimer’s disease. Th

From fatty liver, which often has benign, non-progressive clinical history, to non-alcoholic steatohepatitis, a more serious variant of fatty liver that can lead to cirrhosis and end-stage liver disease, non-alcoholic fatty liver disease encompasses broad spectrum of diseases. The gold standard for determining extent of hepatic fibrosis is still liver biopsy; however, number of noninvasive tests have been established to make diagnosis and assess effectiveness of treatment.

Show MoreThe current research aims to identify the psychological well-being of the educational counselors, as well as to identify the significance of differences in psychological well-being according to the variables (gender, duration of service). The number of scale's items reached (42) items distributed evenly on six dimensions (autonomy, environmental mastery, personal growth, positive relationships with others, purpose in life, self-acceptance), for each field (7) items. The scale was applied to a sample of (400) school counselors (male-female) who were randomly selected from the six directorates in the Baghdad governorate for the academic year 2020/2021. The results showed that the educational counselors in the Baghdad governorate for the si
