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.

A Feminist Discourse Analysis of Writer's Gender Biases about Violence Against Women
...Show More Authors

    The present study is concerned with the writer's ideologies towards violence against women. The study focuses on analyzing violence against women in English novel to see the extent the writers are being affected and influenced by their genders. It also focuses on showing to what extent the writer's ideologies are reflected in their works. Gender influences social groups ideologies; therefore, when a writer discusses an issue that concerns the other gender, they will be either subjective or objective depending on the degree of influence, i.e., gender has influenced their thoughts as well as behaviors. A single fact may be presented differently by different writers depending on the range of a

Antibacterial Activity of Lactiplantibacillus plantarum‎ from Dairy Products ‎Against Some ‎Foodborne Bacteria
...Show More Authors

Lactiplantibacillus plantarum‎, one of lactic acid bacteria (LAB), is found in various foods, ‎‎including dairy products, meat, and vegetables, and most of these bacteria offer beneficial ‎‎effects to humans and animals as potential probiotics with broad-spectrum antimicrobial ‎‎activities. The aim of this study was evaluating the antibacterial efficacy of L. ‎plantarum‎ ‎against ‎some foodborne bacteria isolated from dairy products. This research involved 34 dairy ‎products, ‎including local and imported milk, cheese, and yogurt sold locally in Baghdad ‎province, Iraq, during May ‎‎2022. For the isolation of L. ‎plantarum‎, a special medium called ‎MRS (de Man Rogosa and ‎Sharpe) was applied. Colonie

INACTIVATION OF SELECTED ANTIBIOTICS AGAINST ESCHERICHIA COLI BY VAMIN NUTRITIO- NAL SUPPLEMENTATION
...Show More Authors

Posible interference of vamin with the activity of several antibiotics against E. coli was evaluated in vitro. In MBS- glucose medium, significant growth delay was induced by 8 ug/ml of terramycin (oxytetracycline- polymyxin B) and bactrim (trimethoprim-sulphamethoxazole), and by 16 ug/ml of refocin, lincomycin, and chloramphenicol. Rapid growth inhibition was induced by 32 ug/ml of all an- tibiotic tested separately. Significant inactivation of up to 64 ug/ml of licomycin and bactrim was in- duced by the addition of vamin at a concentration of 1:20 v/v of the medium. This effect was found to be due to the presence of specific amino acids in vamin. Among them is valine, leucine, isoleucine tyrosine, tryptophan, phenylalanine, cysteine, meth

INACTIVATION OF GENTAMYCIN AND STREPTOMYCIN TOXICITY AGAINST E.COLI BY AMINO ACID SUPPLEMENTATION
...Show More Authors

Various nutritional solutions given to patients contain amino acids. Possible interference of this supplementation with selected aminoglycoside antiboiotics, namely gentamycin and streptomycin was evaluated in vitro. In minimal medium, E.coli was inhibited by gentamycin and by streptomycin. Circumvention of this inhibition was obtained with a mixture of 20 amino acids in the medium. Deletion of amino acids revealved that circumvention. specific amino acids were required for such Deletion of the aromatic amino acids or cysteine abolished the protection against gentamycin and streptomycin, while the deletion of the branched chain amino acids abolished the protection against streptomycin only. Thereonine, on the other hand, appears to be essen

INACTIVATION OF B*- LACTAM ANTIBIOTICS AGAINST E. COLI BY VAMIN NUTRITIONAL SUPPLEMENTION
...Show More Authors

ABSTRACT Possible interference of vamin nutritional solution with the activity of several B-lactam antibiotics against E.coli was evaluated in vitro.In Minimal basal salts-glucose medium rapid growth inhibition of sensitive E. coli was induced by 4 µg/ml of ampicillin / cloxaillin, 8 µg/ml of ampicillin, 6 µg/ml of carbencillin, hostacillin, and cephalotin, and by 32 µg/ml of penicillin G and cloxacillin. Significant inactivation of up to 32 µg/ml of carbencillin, cephalotin, penicillin G, and hostacillin was induced by addition of 1:20 v/v vamin. This inactivation was due to the presence of specific amino acids in the mixture. Deletions of amino acids revealed that valine, leucine, isoleucine, tyrosine, tryptophan, phenylalanine, cys

Background

Since the COVID-19 pandemic began, there have been concerns related to the preparedness of healthcare workers (HCWs). This study aimed to describe the level of awareness and preparedness of hospital HCWs at the time of the first wave.

Methods

This multinational, multicenter, cross-sectional survey was conducted among hospital HCWs from February to May 2020. We used a hierarchical logistic regression multivariate analysis to adjust the influence of variables based on awareness and preparedness. We then used association rule mining to identify relationships between HCW confidence in handling suspected

Genomic Fingerprinting of Interleukin IL-12RB2 of Nasal Mucosal Stem Cells in Nasal Polyposes (NPs) of Iraqi Patients
...Show More Authors

The inflammatory reactions cause nasal polyposes (NPs), which contained the paranasal sinuses and the nasal mucous membrane. They consist of recurrent multiple masses originating in the paranasal sinuses then spread from the middle meatus to the nasals cavity, which leads to the nasal blockage that causes the restriction of airflow to the olfactory area. This study aims at clarifying the role of IL-12RB2 polymorphism by using PCR technology in nasal mucosal stem cells in nasal polyps of Iraqi patients and use it as a biomarker. Fifty-eight cases of this study are referred to as nasal surgery, which selected from Dept.of Otolaryngology, Baghdad City, Iraq from May 2013 to January 2014. They were grouped into Control group (022 samples
