خلفية البحث: مع دخول جائحة COVID-19 عامه الثالث ، من الواضح أن آثاره تمتد إلى ما بعد الجهاز التنفسي وهي مهمة سريريًا. قد يكون لهذه العواقب أيضًا تأثير على الصحة ونوعية الحياة. ربما يكون ثلث النساء قد عانين من تغيرات عابرة في أنماط الدورة الشهرية نتيجة للضغوط المرتبطة بوباء COVID-19. وقد يكون هذا التغيير ناتجًا عن التوتر والقلق. يمكن أن يكون عدم انتظام الدورة الشهرية أو غيابها مؤشرًا على انخفاض الخصوبة ، والذي يمكن أن يرتبط بحد ذاته بعدد من الحالات المزمنة ،و قد يتسبب النزيف الحاد في الإصابة بفقر الدم وله تأثير سلبي كبير على نوعية الحياة ويشكل عبئًا اجتماعيًا واقتصاديًا ضخمًا على النساء وأسرهن والخدمات الصحية والمجتمع. الاهداف : ان الهدف من هذه الدراسة هو النظر في تأثير عدوى فيروس كورونا على مستوى الهرمونات للمرأة (استراديول (E2) ، البرولاكتين (PRL) ، الهرمون المنبه للجريب (FSH) ، والهرمون اللوتيني (LH)) ، وكذلك الحالات النزيف الغزير الذي يحدث عند النساء العراقيات قبل انقطاع الطمث المصابات بفيروس كورونا لمدة شهرين إلى ستة أشهر على الأقل. المرضى وطرق العمل/ المواد وطرق العمل: اجريت هذه الدراسة البحثية في مدينة بغداد الطبية (العيادة الاستشارية) ، من تشرين الثاني (نوفمبر) 2021 إلى نيسان (أبريل) 2022. وشملت الدراسة 100 امرأة متزوجة في سن الإنجاب تتراوح أعمارهن بين 18 و 40 سنة. تم تقسيم عينة الدراسة إلى مجموعتين ، المجموعة الاولى 50 امرأة في سن الإنجاب مصابات بالنزيف الحاد بعد الإصابة بـ COVID-19 م لمدة أربعة أشهر على الأقل ، و 50 امرأة غير مصابات بالفيروس التاجي. النتائج: أظهرت نتائج هذه الدراسة ، بمقارنة متوسط ± SD للمجموعتين ، أن مستويات LH كانت ذات دلالة إحصائية عالية لدى النساء اللواتي عانين من نزيف حاد بعد عدوى COVID-19 مقارنة بالنساء غير المصابات بـ COVID-19 ، مع قيمة p 0.000. لم تكن هناك فروق ذات دلالة إحصائية في مستويات FSH بين المجموعتين. كانت مستويات PRL أعلى من الناحية الإحصائية بالنسبة للنساء اللائي عانين من نزيف كبير بعد الإصابة بـ COVID-19 مقارنة بالنساء غير المصابات بـ COVID-19 ، بقيمة p 0.003. كان E2 ذو دلالة إحصائية عالية مقارنة بالنساء اللائي عانين من نزيف مفرط بعد عدوى COVID-19 مقارنة بالنساء غير المصابات. الاستنتاجات: تشير نتائج هذه الدراسة إلى أن النساء بعد الاصابة بـ COVID-19 قد يكون لهن تأثير على أنماط الدورة الشهرية ، ولكن هذا التأثير كان مؤقتًا ويمكن أن يكون بسبب التوتر والقلق الذي يؤثر على HPA ومبايض النساء. قد يؤدي ذلك إلى اضطراب وظائف الجهاز التناسلي الأنثوي ، حيث تظهر مستويات مرتفعة من هرمونات الغدد التناسلية مثل LH و PRL و E2 وأحيانًا تؤدي إلى حالة نزيف حاد بعد الإصابة بفيروس كورونا.
A new series of Sulfamethoxazole derivatives was prepared and examined for antifibrinolytic and antimicrobial activities. Sulfamethoxazole derivatives bear heterocyclic moieties such as 1,3,4-thiadiazine {3}, pyrazolidine-3,5-diol {4} 6-hydroxy-1,3,4-thiadiazinane-2-thione {5} and [(3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-4-yl)diazenyl] {8}. Their structures were elucidated by spectral methods (FT-IR, H1-NMR). Physical properties are also determined for all compound derivatives. Recently prepared compounds were tested for their antimicrobial activity in the laboratory. Each screened compound showed good tendency to moderate antimicrobial activity.
A new 4-thiazolidinone, substitutedbenzylidene-thiazolidinone and tetrazole were synthesized from thiosemicarbazone and hydrazone. The thiosemicarbazone was prepared by the reaction of thiosemicarbazide with aldehyde derivative from L-ascorbic acid in absolute ethanol using glacial acetic acid as a catalyst. 1, 3-thiazolidin-4-ones were synthesized from the condensation of thiosemicarbazones with chloroacetic acid in presence of anhydrous sodium acetate. A 1, 3- thiazolidine-4-one was reaction with several 4-substitutedaldehydes to produce new derivatives with a double bond at the position-5 of the 4-thiazolidinone ring. While the tetrazole compounds were synthesized by 1, 3-cycloaddition reaction of sodium azide and hydrazone compounds in

The importance of shooting emerges as it is the only means of direct scoring and the critical statistic that distinguishes victory from defeat. The researchers observed that previous tests of basic shooting types whether administered individually or in combination do not adequately reflect the complexities of actual game situations. Therefore, the problem lies in the need to address this gap by designing a composite test that simulates various playing conditions related to basic shooting skills. The descriptive approach was adopted, and the research community was delib

Abstract: Background: Optical biosensors offer excellent properties and methods for detecting bacteria when compared to traditional analytical techniques. It allows direct detection of many biological and chemical materials. Bacteria are found in the human body naturally non-pathogenic and pathologically, as they are found in other living organisms. One of these bacteria is Escherichia coli (E. coli) which are found in the human body in its natural and pathogenic form. E.coli bacteria cause many diseases, including Stomach, intestines, urinary system infections, and others. The aim of this study: is sensing and differentiation between normal flora and pathogenic E.coli. Material and method:

theoretically. Two operation modes were employed to study the performance of the solar air heater. An inte- grated mode of continuous operation of the system during the period of (11:00 am – 3:00 pm) and non-integrated mode in which the system stored the solar energy through the day then used the stored energy during the period of (3:00 pm – 8:00 pm). The results of parametric study in case of continuous operating showed that the maximum average temperatur

In this study, a new adsorbent derived from sunflower husk powder and coated in CuO nanoparticles (CSFH) was investigated to evaluate the simultaneous adsorption of Levofloxacin (LEV), Meropenem (MER), and Tetracycline (TEC) from an aqueous solution. Significant improvements in the adsorption capacity of the sunflower husk were identified after the powder particles had been coated in CuO nanoparticles. Kinetic data were correlated using a pseudo-second-order model, and was successful for the three antibiotics. Moreover, high compatibility was identified between the LEV, MER, and TEC, isotherm data, and the Langmuir model, which produced a better fit to suit the isotherm curves. In addition, the spontaneous and exothermic nature of the adsor

So the trials of cement injection at a location with similar soil properties as the erecting site are necessary to assess the performance of the grouted piles. Nevertheless, instead of executing trial-injected piles at the pilot site, which wastes money, time, and effort, the laboratory cement injection devices are essential alternatives for evaluating soil injection ability. This study assesses the performance of a low-pressure laboratory grouting device by improving loose sandy soil injected using binders formed of Silica Fume (SF) as a chemical admixture (10% of Ordinary Portland Cement OPC mass) to di
