Expression of TGFB3 in Pyogenic Granuloma
(2025) Asmaa Ali Hussein
Objective: The aim of the study was to determine the expression of TGFB3 in pyogenic gran-
uloma. Material and Methods: A Pathologist used a double-headed light microscope to calculate-
late cutoff values for all the anTbodies employed in the invesTgaTon. Stained slides were thoroughly washed for 4 minutes with Gill's Hematoxylin SoluTon, dehydrated, and mounted using DPX mounting soluTon. Results: Transforming growth factor beta-3 protein expression
was measured using immunohistochemistry. In pyogenic granuloma tissue expression, negative scores (0) were found in 4.5 of 16 samples (18.1%), whereas positive values (+) were found in 10 of 16 samples (33.06%). Conclusion: TGFB3 is expressed in most pyogenic granulomas.
Assessment of IL-6 and Evaluation of pharmaceutical compounds on biofilm-forming- Acinetobacter baumanni isolated from patients with urinary tract infection
(2025) Haneen Emad Khadum
This study highlights the challenge of ineffective antibiotic treatment for urinary tract infections (UTIs) due
to antimicrobial-resistant strains and biofilm formation by Acinetobacter baumannii (AB), particularly
problematic in immunocompromised individuals. We aimed to investigate pharmaceutical compounds that
could inhibit biofilm production in A. baumannii isolates associated with UTIs. In the study conducted from
October 2023 to February 2024, interleukin IL-6 levels were measured using ELISA. Compounds
Cinnamic(C) and Gallic (G) acids were evaluated for their minimum inhibitory concentration (MIC) and
minimum bactericidal concentration (MBC) through broth microdilution. Bacterial susceptibility to antibiotics
was assessed using the Kirby disk diffusion method and the Vitek-2 compact system with an AST card.
Biofilm formation was analyzed using Congo red staining and a 96-well ELISA plate, and the efficacy of
compounds C and G in treating biofilms was evaluated using the same method. Results showed that UTI
patients had a mean IL-6 level of 19.00±1.581 pg/mL, significantly higher than the control group (mean IL-6
level: 7.400±1.140 pg/mL; p < 0.0001). Resistance rates among A. baumannii isolates were considerable, with
varying percentages for different antibiotics. Gallic and cinnamic acids demonstrated antibacterial activity,
inhibiting biofilm formation in A. baumannii at concentrations ranging from 0.5 to 128 mg/mL (p ≤ 0.01).
These compounds effectively suppressed biofilm formation across A. baumannii strains. In conclusion, IL-6
shows promise as a biomarker for diagnosing UTIs. Notably, gallic and cinnamic acids significantly reduced
biofilms of extensively drug-resistant (PDR) A. baumannii strains, suggesting their potential therapeutic value
against multidrug-resistant biofilms
Assessing the Durability of Eco-Friendly Mortars with Treated and Untreated Eggshell Powder as a Cement Substitute
(Springer Nature, 2025-10-13) Nahla Hilal; Taghreed Khaleefa Mohammed Ali; Abdulrahman S. Mohammed; Ayad S. Aadi; Zouaoui R. Harrat
This study investigates the use of treated and untreated eggshell powder (ESP) as a sustainable partial substitute for
cement in mortar. ESP was incorporated at 5% and 7.5% replacement levels, with treated samples burned at 900 °C for
0.5, 1, and 2 h. Compressive strength tests revealed that mortar containing 5% of eggshells burned for 2 h achieved a 25%
strength increase after 90 days, while 7.5% replacement led to a 22.22% increase. Durability tests under acidic (MgSO₄)
and alkaline (NaOH) environments for up to 90 days showed minimal variation in hardened mixture density (± 5.39%)
and compressive strength reduction remained below 6.98% for all treated ESP mixes. These findings demonstrate that
properly processed ESP can significantly enhance the mechanical strength and durability of cement mortar, offering a
viable eco-friendly alternative to traditional cement.

أحكام الخطأ في التصميم المعماري في عقود مقاولات البناء
(مجلة النهرين للعلوم القانونية/ العدد3/الجزء الثاني /المجلد 27, 2025-08-27) م. نور حسين علي و م, احمد فائز عبد
ان اعداد التصميم في مقاولات البناء من المهام الدقيقة والمعقدة لأنه سيترتب عليه تشييد مبان ومنشآت ، ويستلزم اعداده مراعاة الاصول الفنية والالتزام بالقوانين والتعليمات ذات العلاقة ، والمشكلة التي قد تطرح في هذا الجانب هو ما اذا وجد خطأ في التصميم مما يقتضي معه قيام مسؤولية من وضعه سواء أكان المهندس المعماري أو المقاول أو رب العمل ، فإذاكان يقتصر عمل المهندس المعماري على وضع التصميم دون الاشراف على تنفيذ البناء ، فلا يكون مسؤولا الا عن عيوب التصميم ، وقد يترتب على ذلك الخطأ قيام الضمان العشري أو تعديل الاجر بالزيادة اذا كان تعديل التصميم أو الاضافة اليه بسبب خطأ رب العمل أو تم بناءً على الاتفاق بين الاخير والمقاول ، وقد يلزم المهندش المعماري أو المقاول عند ثبوت اشتراكهما في الخطأ في التصميم بتعويض صاحب العمل عن الضرر الذي لحقه جراء ذلك ، وازاء ذلك كله قد لا تكون هناك نصوص قانونية كافية ابعض المسائل الدقيقة التي تتعلق بصور هذا الخطأ واثاره
