خلفية البحث: مرض السكري هو عامل خطر لأمراض القلب والأوعية الدموية وتصلب الشرايين وسبب مهم للوفاة. يرتبط خلل الدهون في الدم بشكل شائع بمرض السكري من النوع الثاني ويعتبر مؤشر تصلب الشرايين في البلازما علامة قوية للتنبؤ بخطر الإصابة بتصلب الشرايين وأمراض القلب التاجية. الهدف من البحث: دراسة ارتباط المؤشرات الدهنية لتصلب الشرايين لدى المرضى العراقيين المصابين بالسكري من النوع الثاني ولديهم أمراض قلبية وعائية. المرضى وطرق العمل: أجريت هذه الدراسة السريرية في مستشفى بغداد التعليمي/ مدينة الطب - بغداد في الفترة من تشرين الأول 2022 ولغاية شباط 2023. تم مشاركة 60 مريضًا مصاباً بالسكري من النوع الثاني في هذه الدراسة. ثلاثون مريضا منهم كانوا يعانون من أمراض القلب والأوعية الدموية و 30 غير مصابين بأمراض القلب والأوعية الدموية. تراوحت أعمارهم بين 40-55 سنة. تم اختيار 30 فردًا سليما كمجموعة سيطرة. النتائج: كان هناك ارتفاع كبير في فحوصات نسبة السكر والدهون في الدم لدى مرضى السكري المصابين بأمراض القلب والأوعية الدموية مقارنة مع أولئك الذين لا يعانون من أمراض القلب والأوعية الدموية ومجموعة السيطرة. أظهرت النتائج الحالية مستويات مرتفعة من نسب الدهون لدى مرضى السكري المصابين بأمراض القلب والأوعية الدموية. كشفت النتائج أيضًا عن مستويات عالية من البروتين الدهني غير عالي الكثافة لدى مرضى السكري المصابين بأمراض القلب والأوعية الدموية (241.8 ± 12.24 ملغم/ ديسيلتر) مقابل (150.1 ± 7.12 و 68.9 ± 5.1 ملغم/ ديسيلتر) لأولئك الذين لا يعانون من أمراض القلب والأوعية الدموية ومجموعة السيطرة على التوالي. كان مؤشر تصلب الشرايين للبلازما لدى مرضى السكري المصابين بأمراض القلب والأوعية الدموية مقارنة بمجاميع مرضى السكري والأصحاء (0.8 ± 0.09) مقابل (0.7 ± 0.03 و 0.2 ± 0.08) على التوالي. كان هناك ارتباط معنوي موجب بين مؤشر تصلب الشرايين للبلازما والعوامل الجسمية، صورة السكر والدهون في الدم مع نسبها لدى مرضى السكري مع وبدون أمراض القلب والأوعية الدموية. الاستنتاجات: تؤكد نتائج هذه الدراسة أن مؤشرات الدهون هي مؤشرات خطر لضبط نسبة السكر في الدم بقيمة تنبؤية أعلى من العوامل التقليدية. أيضًا، ممكن اعتبار البروتين الدهني غير عالي الكثافة ومؤشر تصلب الشرايين في البلازما من العوامل الهامة للسيطرة على نسبة السكر في الدم.
At a temperature of 300 K, a prepared thin film of Ag doped with different ratios of CdO (0.1, 0.3, 0.5) % were observed using pulse laser deposition (PLD). The laser, an Nd:YAG in ?=1064 nm, used a pulse, constant energy of 600 mJ ,with a repetition rate of 6 Hz and 400 pulses. The effect of CdO on the structural and optical properties of these films was studied. The structural tests showed that these films are of a polycrystalline structure with a preferred orientation in the (002) direction for Ag. The grain size is positively correlated with the concentration of CdO. The optical properties of the Ag :CdO thin film we observed included transmittance, absorption coefficient, and the energy gap in the wavelength range of 300-1100
... Show MoreA simple indirect spectrophotometric method for determination of mebendazol in pure and pharmaceutical formulation was presented in this study. UV-Visible spectrophotometry using the optimal conditions was developed for determination of mebendazole in pure drug and different preparation samples. The method is based on the oxidation of drug by nbromosuccinimide with hydrochloric acid and the left amount of oxidizing agent was determined by the reaction with tartarazine and the absorbance was measured at 428 nm. Calibration curves were linear in the range of 5 to 30 µg.mL-1 with molar absorptivity 8437.2 L.mol-1 .cm-1 . The limits of detection and quantification were determined and found to be 0.7770 µg.mL-1 and 2.3400 µg.mL-1 respec
... Show MorePolycrystalline Cadmium Oxide (CdO) thin films were prepared using pulsed laser deposition onto glass substrates at room temperature with different thicknesses of (300, 350 and 400)nm, these films were irradiated with cesium-137(Cs-137) radiation. The thickness and irradiation effects on structural and optical properties were studied. It is observed by XRD results that films are polycrystalline before and after irradiation, with cubic structure and show preferential growth along (111) and (200) directions. The crystallite sizes increases with increasing of thickness, and decreases with gamma radiation, which are found to be within the range (23.84-4.52) nm and (41.44-4.974)nm before and after irradiation for thickness 350nm and 4
... Show MoreWe study in this paper the composition operator that is induced by ?(z) = sz + t. We give a characterization of the adjoint of composiotion operators generated by self-maps of the unit ball of form ?(z) = sz + t for which |s|?1, |t|<1 and |s|+|t|?1. In fact we prove that the adjoint is a product of toeplitz operators and composition operator. Also, we have studied the compactness of C? and give some other partial results.
Objectives To compare the clinical efficacy of microvascular decompression surgery (MVD) and gamma knife radiosurgery (GKR) as a treatment for patients with primary trigeminal neuralgia (TN) and evaluate the outcome regarding pain relief, recurrence, and complications with both modalities of treatment. Patients and Methods A randomized prospective study conducted in SaadAlwitry Neurosciences Hospital, Baghdad, Iraq. Eighty-four patients with TN from January 2016 to January 2018, 45 patients had GKR while 39 patients treated with MVD. The pain evaluated pre-and post-operatively using the Barrow Neurological Institute Pain Intensity scale (BNIPI), visual analog scale (VAS) and Brief Pain Inventory Facial (BPI-Facial) scoring systems. In GKR p

Show MoreThe prevalence of using the applications for the internet of things (IoT) in many human life fields such as economy, social life, and healthcare made IoT devices targets for many cyber-attacks. Besides, the resource limitation of IoT devices such as tiny battery power, small storage capacity, and low calculation speed made its security a big challenge for the researchers. Therefore, in this study, a new technique is proposed called intrusion detection system based on spike neural network and decision tree (IDS-SNNDT). In this method, the DT is used to select the optimal samples that will be hired as input to the SNN, while SNN utilized the non-leaky integrate neurons fire (NLIF) model in order to reduce latency and minimize devices

The collected samples were analyzed for gross alpha /beta radioactivity using Ludlum model 3030 and measurement particles activity in Al Tuwaitha nuclear site and the surrounding areas for the period from 28/12/2016 to 13/4/2017.The measurement of activity concentrations ranged from (0.42±0.03 to 4.18±0.13) Bq/m3 for alpha particles and from(0.93±0.06 to 9.21±0.26) Bq/m3for beta particles. The activity concentration of nuclides inversely proportional with air temperature and wind speed while humidity is directly proportional with it. Highest value of activity concentration has been found at(
... Show MoreThis paper introduces a complete design and simulation of a controller for the double fed induction generator (DFIG) turbine. The work also included the solar updraft tower (SUT) design to supply Al-Mahmoudia hospital in Baghdad/Iraq. The design includes the daily average load estimation, annual solar irradiance and, temperature monitoring, and logging.
According to the data obtained from the Ministry of Science and Technology, Baghdad has low wind speed. Therefore, the (SUT) has been designed to generate electrical power depending on the difference between the external and internal air temperature. The temperature difference will generate a suitable airspeed to drive the wind turbine, connected to the proposed (DFIG) generators
