حصاة الحالب واعراضها تؤثر على حياة المريض بصوره سلبيه، عدة علاجات متوفرة لعلاج حصاة الحالب من ضمنها مراقبه المريض، استخدام ادويه تفتيت الحصاة، استخدام موجات الفوق الصوتية تفتيت الحصاة بناظور الحالب، استخراج الحصاة جراحيا او بالناظور البطني, استخدام ناظور الحالب وتفتيت الحصاة بالليزر هي الطريقة المفضلة لعلاج حصاة اسفل الحالب. الهدف من الدراسة:لمقارنه تأثير ومضاعفات استخدام تقنيه الطحن او تقنيه التكسير لحصاة أسفل الحالب باستخدام الليزر وذلك بمقارنه وقت العملية، معدل التخلص من الحصى، معدل احتياج وضع قسطره الحالب والمضاعفات داخل العملية. المرضى والأساليب: ادرج في هذه الدراسة 120 مريض تم تقسيمهم الى مجموعتين : (الأولى) تكسير حصاة الحالب باستخدام تقنيه الطحن وتم تقسيمها الى مجموعتين الأولى حصاة بين 10-15 ملم والثانية حصاة اصغر من 10 ملم, و(الثانية) باستخدام تقنيه التكسير وتم تقسيمها الى مجموعتين الأولى حصاة بين 10-15 ملم والثانية حصاة اصغر من 10 ملم في مستشفى الشهيد غازي الحريري للجراحات التخصصية للفترة من كانون الأول 2019 الى تموز 2022 , تمت المقارنة بين كلتا الطريقتين من حيث وقت العمليه,معدل التخلص من الحصاة، معدل وضع قسطره الحالب, مضاعفات حدثت خلال العملية. النتائج: وقت العملية في النوع الأول (تقنيه الطحن) أكثر من النوع الثاني (تقنيه التكسير) مع وجود فرق كبير ذو دلاله إحصائية، معدل التخلص من حصاة الحالب في النوع الأول أكثر من النوع الثاني بدون وجود فرق كبير ذو دلاله إحصائية، احتياج وضع قسطره الحالب أكثر في النوع الثاني مقارنه بالنوع الأول مع وجود فرق كبير ذو دلاله إحصائية. من حيث المضاعفات خلال العملية، أكثر بالنوع الثاني مقارنه بالنوع الأول بدون وجود فرق كبير ذو دلاله إحصائية. الاستنتاج:ان تفتيت حصاة الحالب باستخدام تقنيه الطحن ذو مضاعفات اقل داخل العملية وذو احتياج اقل لوضع قسطره الحالب، ولكن وقت العملية أطول،تفتيت حصاة الحالب باستخدام تقنية التكسير وقت عمليه أقصر وأكثر مضاعفات داخل العملية وأكثر احتياج لوضع قسطره الحالب.
The research deals with the interchange of the sign transformed from the universal to the local in the theatrical show through the direction processing in the production of a communicative artistic discourse and message, thus making the process of reading the speech and recognizing it by taking into account the cultural differences, customs and local rituals of each country, region, or area. The problem of the research was focused on answering the following question: What are the requirements for the sign in terms of its transformation between the universality and locality in the read-out?

It is method of accounting is based on measuring the costs according to the Attributes that the product is designed on this basis and according to achievement levels of all the Attribute of the product attributes. This research provides the knowledge foundations of this approach and its role in the market-oriented compared to the Activity based costing as shown in steps to be followed to apply for this Approach. The research problem in the attempt to reach the most accurate Approach in the measurement of the cost of products from th

Show MoreFlexible molecular docking is a computational method of structure-based drug design to evaluate binding interactions between receptor and ligand and identify the ligand conformation within the receptor pocket. Currently, various molecular docking programs are extensively applied; therefore, realizing accuracy and performance of the various docking programs could have a significant value. In this comparative study, the performance and accuracy of three widely used non-commercial docking software (AutoDock Vina, 1-Click Docking, and UCSF DOCK) was evaluated through investigations of the predicted binding affinity and binding conformation of the same set of small molecules (HIV-1 protease inhibitors) and a protein target HIV-1 protease enzy

Teeth with various depths of white spot lesions were immersed in either splat mouthwash, Biorepair mouthwash, Sensodyne mouthwash, or artificial saliva (control)twice daily for one minute for 4 weeks and 8 weeks at 37°C. After this immersion procedure, lesion depth was measured using a diagnosed pen score. A one-way analysis of variance, Dunnett T3 and Tukey's post hoc α = .05 were used to analyze the testing data. Splat mouthwash enhanced the WSL remineralization and made the lowest ΔF compared with other mouthwashes in shallow and deep enamel after 4 and 8 weeks of treatment. In the repair groups, after 4 weeks

The problem was the negative effects of the organizational silence on the morale of the employees and consequently their performance and the quality of function life. To collect the data and information needed to measure the two variables of research conducted in the health center / Sulaikh by taking a sample of (40) employees to test the hypotheses of research through the survey of their views, using statistical tools non parametric using the program. The most important recommendations were the establishment of training workshops fo

Show MoreThe present study aimed to investigate the anatomy, histology, and immunohistochemistry of parathyroid gland in two Iraqi mammals (Weasel, Herpestes javanicus and Long-ear hedgehog, Hemiechinus auritus) as a comparative study. A total of (20) animal for each species were used in the present study. Animals collected were immediately anesthesia and dissected to get the parathyroid gland. Methods of Humason and Bancroft and Stevens were employed for histological techniques. Different stains were used (Hematoxylin- Eosin stain-(H & E), Periodic Acid Schiff stain-(PAS), Azan stain, and Methyl Blue stain-(MB)) for staining the histological sections. Anti-calcitonin, code140778 marker used for immune-histochemical study. Results of the present stu

Evaluate its performance via (ZEMAX) outputs, as bright Spot Diagram via (RMS), Ray Fan Plot, Geometric Encircled Energy and the value of Focal shift. Then study the effect of field of view on the outputs in the room temperature.
Abstract: The aim of this study is to assess the effectiveness of 940 nm diode laser in comparison to Endoactivator in elimination of smear layer in terms of radicular dentin permeability and ultra-structural changes of root canal walls by SEM evaluation. Twenty-eight single-rooted extracted lower premolars were instrumented up to size X4 (protaper Next, Dentsaply) and divided into two experimental groups according to the irrigation system, G1; activated by EndoActivator and G2; activated by Diode laser 940 nm, CW mode, 1.7 W. Afterward, the roots were made externally impermeable, filled with 2%methylene blue dye, divided horizontally into three segments representing the apical, middle, and coronal thirds then examined under stereo- micr
