In this research, the researchers addressed the issue of digital transformation and its impact on the development of medical maintenance, and this topic is very important in the field of medical engineering. The researchers chose the military Hospital in Medina as his study location. The study aimed to identify and address the main challenges facing the digital transformation of medical maintenance at the Military Hospital in Medina. It seeks to analyze the current state of digitalization in medical maintenance operations, identify areas requiring improvement, and propose effective strategies to overcome obstacles. The study will evaluate the impact of digital transformation on efficiency, cost-effectiveness, patient care, and overall operational performance. At the end of the research, the researchers reached several results, including that introducing digital systems and technologies into medical maintenance can increase efficiency in various aspects, such as scheduling equipment maintenance, inventory management, and resource allocation. Researchers may find evidence of reduced downtime, streamlined workflow, and optimized use of resources. In addition, digital transformation initiatives in medical maintenance may focus on ensuring the safety and reliability of medical equipment. Research can reveal improvements in equipment reliability, decreased equipment failure rates, and improved patient safety outcomes. The researchers also recommended developing a comprehensive strategy for digital transformation: Based on the research results, it is recommended to develop a well-defined strategy that defines the hospital’s vision, goals, and roadmap for the digital transformation of medical maintenance. This strategy should consider factors such as technology selection, resource allocation, timeline, and change management. Invest in a solid digital infrastructure: To support the digital transformation of medical maintenance, the hospital must invest in a reliable and secu

The rate of elapsed polymerization of polyhydroxyethylacrylate in gelatin has been studied to investigate the effect of co-monomers consumption at a given dose. The polymer gel dosimeters consisted of 2%～4% N,N-methyelene-bis-acrylamide cross-linker,2%～4% 2-hydroxyethylacrylate monomer and gelatin at 3% and 5%. The dosimeters were irradiated by using 60Co teletherapy γ-ray source up to 20 Gy at a constant dose rate. The relaxation rate of water proton in the dosimeters at different doses and co-monomer concentrations were measured using a nuclear magnetic resonance spectroscopy. The rate of elapsed polymerization decreases with increasing the dose and the initial concentration of co-monomers. The rate of consumption of co-monomers increases with an increase of the polymerization and the gelatin content of the polymer gel.

The aim of our study was to explore the antioxidant potential of Moroccan saffron stigmas（SS） and examine their performance as a natural antioxidant in enhancing the stability and quality properties of edible sunflower oil（SO）, with a focus on understanding the critical importance of edible oil stability for predicting quality deterioration during storage. Bearing this in mind, our research was designed to compare the efficacy of three concentrations of dried SS（at 0.2%, 0.3%, and 0.6%） against tocobiol（a synthetic antioxidant） as a positive control（at 0.3% concentration）. This comparison was conducted under three distinct storage conditions namely accelerated ageing（60 ℃）, exposure to light at ambient temperature, and darkness, to evaluate their impact on preventing severe oxidation and extending oil shelf-life. Oxidation state evolution was evaluated through peroxide value（PV）, free fatty acid（FFA）, anisidine value（p-AV）, K270value（conjugated trienes）, total oxidation index（TOTOX）, iodine value（IV）, and fatty acid composition（FA）. Our results revealed notable differences in stability tracking parameters. Specifically, these parameters were higher in samples stored under accelerated conditions, followed by the samples stored in ambient light, while those stored in darkness showed the highest stability among the three storage conditions. Supplementation of sunflower oil with SS and tocobiol significantly enhanced its oxidation stability. Notably, SS exhibited exceptional effectiveness in stabilizing sunflower oil regardless of SS dose, with the highest efficacy observed at 0.6%. This was evidenced by the slower rate of oxidation parameters under various storage conditions, highlighting a superior antioxidant activity compared to both the non-enriched oil and tocobiol-enriched oil. Furthermore, saffron stigmas, used as a natural supplement,contributed to the preservation of polyunsaturated fatty acids, indicating its potential as a robust source of natural antioxidan

Background: Chronic liver disease is a disease process of the liver that involves a process of progressive destruction and regeneration of the liver parenchyma leading to fibrosis and cirrhosis chronic liver disease refers to disease of the liver which had lasted over a period of 6 months. This study was conducted to evaluate the D-dimer levels among Sudanese patients with Chronic Liver Diseases. Materials and Method: In IbnSina hospital, Khartoum state, Sudan, a case control study was conducted. For this study, 100 participants were selected, 70 of them were patients known diagnosed by chronic liver diseases as a test group. Other 30 participants were normal healthy individual as control group. The plasma D-dimer level was measured by using MINDRAY auto analyzer BS 380). Results: In this study, the plasma D-dimer level has statistically significantly higher in chronic liver diseases patients (mean ± SD 0.634 ± 0.215 ug/l) compared to normal healthy control group (mean ± SD 0.223 ± 0.077 ug/l) with P value 0.000. Conclusion: The present study revealed that the D-dimer levels were statistically significant higher in chronic liver diseases patients.

跟腱疾病通常是由于过度劳损造成的,常发生于体育运动、繁重体力劳动等场合,呈逐年递增趋势。肌腱损伤常常不能自愈,治疗这一运动疾病需要生物工程学家的参与。本研究设计了一种新的、精确易用的冷冻夹具,解决了以往肌腱损伤修复基础研究中力学测试困难的困境。该冷冻夹具通过液氮将预冷的肌肉在力学测试过程中保持在冷冻状态,从而解决了拉伸测试过程中肌肉/肌腱的相对滑移和应力集中问题。该夹具还设计了一个生理盐水浴环境,从而使整个测试过程很好的模拟了生理环境,保证了体外测试数据能真实体现体内生理状况。本研究以大鼠跟腱为对象,利用设计的冷冻夹具进行拉伸测试。共20个待测试样,随机分为4组,分别测试不同预冷方法、样品拉伸环境、夹具移动速度下跟腱的力学特性。具体分组和测试方法如下：A组,将样品放置-20℃冷冻1周,生理盐水浴环境拉伸,夹具移动速度为10mm/min;B组,将样品放置液氮速冻1分钟,生理盐水浴环境拉伸,夹具移动速度10mm/min;C组,将样品放置液氮速冻1分钟,室温（25℃）空气环境拉伸,夹具移动速度10mm/min;D组,将样品放置液氮速冻1分钟,室温（25℃）空气环境拉伸,夹具移动速度500mm/min。记录力-位移曲线,本研究获取了4组样品的最大断裂力、断裂点最大位移、杨氏模量,结果分别如下：A组,119.2±25N,1.868±0.174mm,264.64±108.78MPa;B组,90.5±13N,3.6838±0.8825mm,66.926±24.743MPa;C组,70±20N,2.966±1.279mm,86.822±27.915MPa;D组,53±10N,2.130±0.719mm,38.078±9.765MPa。结果经过统计分析表明：-20℃冷冻1周和液氮速冻1分钟的样品处理方式最大断裂力无显著差异,生理盐水浴的拉伸环境最大断裂力显著大于室温（25℃）空气环境,夹具移动速度在低速（10mm/min）和高速（500mm/min）时最大断裂力无显著差异,但低速时断裂点最大位移更均一。
