| 1 | 射线通过抑制内膜低密度脂蛋白聚集影响早期动脉粥样硬化显示文摘骨髓移植常用于研究造血细胞在动脉粥样硬化中的作用。在小鼠骨髓移植后,主动脉弓病变部位变小了。该研究旨在明确骨髓移植对早期动脉粥样硬化的抑制作用,并阐明其机制。方法和结论:对低密度脂蛋白胆固醇(low-density lipoprotein cholesterol,LDL-C)受体基因敲除(Ldlr-/-)小鼠行全身γ射线照射,骨髓重建,并给予6周恢复期。研究升主动脉弓的动脉粥样硬化情况,并与未行骨髓移植的小鼠进行比较。在3、6、12周的高胆固醇膳食后,骨髓移植的小鼠病变部位中性脂类和髓细胞分布减少。骨髓移植后,病变的合并和高度被抑制,但横向增长受抑制较小。 | Ikeda J Scipione CA Hyduk S Althagafi MG Atif J Dick SA Rajora MA Jang E Emoto T MurakamiJ Ikeda N Ibrahim HM Polenz CK Gao X Tai K Jongstra-Bilen J Nakashima R Epelman S Robbins C Zheng G Lee WL MacParland SA Cybulsky MI 陈嘉睿(译) 练桂丽(审校) | 2021 | 中华高血压杂志2021，29，5： | 0 |
| 2 | Coronavirus disease 2019 and renal transplantation显示文摘Ever since the severe acute respiratory syndrome virus causing coronavirus disease 2019(COVID-19)struck the world,global health strategies have changed significantly.According to the Centers for Disease Control and Prevention,kidney transplant recipients are stratified as being high risk of developing fatal illness from COVID-19 infection.Kidney transplant is the gold-standard treatment for end-stage kidney disease subjects.During the pandemic,significant concerns have emerged regarding continuation of kidney transplant surgeries and management of kidney transplant recipients post-transplant.The added risk of immunosuppression in this cohort was and remains a theoretical concern,posing a potential risk of transplantation rather than benefit.This comprehensive review aims to cover most of the faced challenges in kidney transplantation in different stages of the pandemic.In addition,it will elucidate the epidemiology,nature,course of the disease,surgical consideration in donors and recipients as well as role of immunosuppression and management of COVID-19 infected kidney transplant recipients during these extraordinary circumstances. | Mahmoud Nassar Nso Nso Jonathan Ariyaratnam Jasmine Sandhu Mahmoud Mohamed Bahaaeldin Baraka Atif Ibrahim Mostafa Alfishawy David Zheng Harangad Bhangoo Karim M Soliman Matthew Li Vincent Rizzo Ahmed Daoud | 2021 | World Journal of Clinical Cases2021，9，27： | 0 |
| 3 | Automated Test Case Generation from Requirements: A Systematic Literature Review显示文摘Software testing is an important and cost intensive activity in software development.The major contribution in cost is due to test case generations.Requirement-based testing is an approach in which test cases are derivative from requirements without considering the implementation’s internal structure.Requirement-based testing includes functional and nonfunctional requirements.The objective of this study is to explore the approaches that generate test cases from requirements.A systematic literature review based on two research questions and extensive quality assessment criteria includes studies.The study identies 30 primary studies from 410 studies spanned from 2000 to 2018.The review’s nding shows that 53%of journal papers,42%of conference papers,and 5%of book chapters’address requirementsbased testing.Most of the studies use UML,activity,and use case diagrams for test case generation from requirements.One of the signicant lessons learned is that most software testing errors are traced back to errors in natural language requirements.A substantial amount of work focuses on UML diagrams for test case generations,which cannot capture all the system’s developed attributes.Furthermore,there is a lack of UML-based models that can generate test cases from natural language requirements by rening them in context.Coverage criteria indicate how efciently the testing has been performed 12.37%of studies use requirements coverage,20%of studies cover path coverage,and 17%study basic coverage. | Ahmad Mustafa Wan M.N.Wan-Kadir Noraini Ibrahim Muhammad Arif Shah Muhammad Younas Atif Khan Mahdi Zareei Faisal Alanazi | 2021 | Computers, Materials & Continua2021，，5： | 0 |
