Covid-19: Emerging Considerations for Body Sourcing and Handling. A Perspective View from Nigeria

The current Coronavirus disease (Covid-19) pandemic has spread to about 220 countries of the world and has resulted in a significant number of deaths globally. Infections are still on the rise, and the impact on the global death rate could be devastating. There are fears over the likely impact of a large number of deaths on body sourcing and handling of cadavers for teaching and research. Historically, epidemics come with several challenges and have often led to some level of negligence of ethical practices and health and safety regulations associated with body sourcing and handling. The authors highlighted some emerging problems in this article, focusing on Africa and Nigeria in particular. These problems include a higher risk of coronavirus exposure for body handlers, shortage of cadavers for teaching and learning, a lack of standard regulations leading to unethical body sourcing and handling, and a lack of monitoring and collaboration needed for a well-coordinated Covid-19 pandemic response strategy. If these issues are ignored, the previous gains made in anatomical ethical practices may be destroyed. Some useful recommendations for policymaking geared toward prevention or curtailing these emerging issues have been instilled in this article.

Genetic Polymorphism of Angiotensin II Type 1 Receptors and Their Effect on the Clinical Outcome of Captopril Treatment in Arab Iraqi Patients with Acute Coronary Syndrome (Mid Euphrates)

Genetic variation in the angiotensin II type 1 receptor (AT1R) has an important effect on the outcome of acute coronary syndrome (ACS) initiated treatment with captopril. This study aims to investigate the impact of genetic polymorphism of AT1R (rs5186 and rs275651) on the ACS outcome in Iraqi patients treated with captopril. A total of 250 Iraqi individuals with ACS were included in this case—control study and they were divided into two study groups; Study group 1 included 125 participants who were prescribed captopril, 25 mg twice daily and study group 2 included 125 participants who received no captopril as part of their ACS treatment (control study). The AT1R gene (rs5186) CC genotype was found to be associated with ST-elevation myocardial infarction (STEMI) (Odd’s ratio (O.R) = 1.2, P = 0.7), while AC was associated with Non-ST-elevation myocardial infarction (NSTEMI) and unstable angina (UA) (O.R = 1.2, P = 0.8). AC genotype is more prone to have Percutaneous coronary intervention (PCI) after ACS attack (O.R = 1.2, P = 0.6). CC genotype had a risk to get less improvement (O.R = 1.6, P = 0.5), so might require higher doses of captopril during acute coronary insult. The AT1R gene (rs275651) AA genotype was associated with UA (O.R = 1.3, P = 0.9). AA and AT genotypes were more prone to have PCI after ACS attack (O.R = 3.9 P = 0.2, O.R = 3.5, P = 0.3 respectively) and thus requiring higher doses of captopril. We conclude that the AT1R rs5186, rs275651 genetic polymorphisms might partially affect the clinical outcome of ACS patients treated with captopril and might have captopril resistance which requires higher doses.     

习近平新时代体育强国思想的马克思唯物主义立场及价值引领

运用文献资料法、辩证分析法、逻辑推理法等研究方法，对习近平新时代体育强国思想的马克思唯物主义立场进行了演绎与阐释。研究认为：在马克思唯物主义立场层面，习近平新时代体育强国思想坚持体育强国梦与实现中华民族伟大复兴中国梦一脉相承的历史唯物主义立场和普遍联系的辩证唯物主义立场；坚持在体育强国建设进程中遵循问题导向的唯物主义本体论立场；坚持体育强国建设要利用好国际与国内两种资源的唯物主义内外因辩证关系的立场。在新的历史时期，习近平新时代体育强国思想引领着竞技体育、群众体育、体育产业等领域的发展理念和价值，创新与发展了马克思主义哲学的实践结构和理论视角，为开创新时代中国特色社会主义体育事业的新局面提供了坚实的理论基础和实践支持。     

太极拳运动对老年肥胖Ⅱ型糖尿病患者神经肽Y的影响

目的：本文通过对老年肥胖Ⅱ型糖尿病患者血浆神经肽Y水平的对比研究，探讨太极拳运动对老年肥胖Ⅱ型糖尿病患者产生作用的神经内分泌机制。方法：选取老年肥胖Ⅱ型糖尿病患者16人，按自愿原则分为两组，一组为太极拳运动组(10人)，另一组为随意运动组(6人)。各自进行每天1小时，为期3个月的运动锻炼，观察锻炼前及锻炼后空腹、安静状态下的血浆神经肽Y(NPY)水平、血糖和体重指数等指标的变化。结果：太极拳运动组血浆神经肽Y水平下降，其中伴有高甘油三脂血症者6人，NPY水平下降；伴有高胆固醇血症者4人，NPY水平升高。而随意运动组血浆神经肽Y水平变化不显著。结论：太极拳运动对血浆神经肽Y水平的影响，表明了太极拳运动改善老年肥胖Ⅱ型糖尿病患者代谢紊乱的机制与其时机体神经内分泌系统的调节密切相关。     

试论北京奥运会前我国青少年的奥林匹克教育问题

我国艺术体操集体项目艺术值加分分值偏低的现状分析与对策——2002年5A杯全国艺术体操冠军赛调研

采用比赛现场与录相观察、献研究、访问调查等方法，对5A杯全国艺术体操冠军赛集体项目A2加分分值偏低现象做分析，结果表明：独创性的加分是一个空白；身体动作使用的加分因难度不成立而不能给予加分的现象普遍存在；器械的使用加分因器械运用单调和与难度配合时不合规则要求而不能加分的数量过半；熟练性加分因抛器械高度不够，或接器械时未能达到规则要求而不能加分的数量达2／3，目前只有运动员之间合作的加分是我国集体项目A2加分中的主力。     

高校女生血清睾酮、皮质醇、最大吸氧量及运动能力随月经周期规律性变化的特征

对高校女生血清睾酮(T)、皮质醇(C)水平及VO2max等指标随月经周期而变化特征的研究结果表明：血清T、C水平、T／C值及VO2max的变化随月经周期均有一定变化规律；T／C值的波动和VO2max的波动一致。提示：女大学生存在最大运动能力变化周期，但与运动员不同，个体差异较大；其健身运动于月经周期的不同时期应有不同的安排和内容。
