不同变形条件的HPS485wf钢动态再结晶仿真

为了揭示HPS485wf钢动态再结晶组织演变行为,在不同的单道次热压缩变形条件下,进行了该钢动态再结晶过程的CA仿真．结果表明：随着变形温度升高,动态再结晶的孕育期缩短、速度加快,平均晶粒尺寸增加;随着应变速率加快,动态再结晶的孕育期延长、速度减慢,平均晶粒尺寸减小．

Cancer in south Karnataka and its paradoxical relation to diabetes mellitus

The present work identifies a high incidence of oral cancer in south Karnataka. The primary reason for this could be due to extensive addiction to tobacco alone or tobacco and alcohol in most of these patients. The next in intensity was cancer of the breast and cervix among the cancer patients surveyed in south Karnataka. Majority of these patients had no specific addiction and the exact reason for this high incidence remains unclear. Only a small percentage of patients exhibited other types of organ related cancer. It has been reported that the incidence percentage of diabetes mellitus and cancer in India, parallel each other. However, we observed a low incidence of diabetes mellitus patients also having cancer in south Karnataka. Though the exact reason for this remains unclear an attempt has been made here to explain this phenomenon, hypothetically using information in literature, which suggests a suppression of cellular regenerative activity by sugar and sugar phosphates. Cellular regenerative activity is well known to be a prerequisite for cancer.     

组织免疫系统的构建及运行机制——对大亚湾核电站的案例研究

借鉴医学免疫理论，构建了组织免疫系统分析框架，探讨企业组织如何构建免疫系统以及免疫系统如何发挥作用的机制。对大亚湾核电站的案例研究揭示，认知、防御和记忆功能是组织免疫系统的关键要素，任何一个要素的缺失或失灵都会破坏免疫系统的正常应答。组织免疫系统的建立对于避免复杂系统的失败是非常重要的。

论自然人破产制度建立之下侵权之债的破产免责制度构建

当前学界关于建立自然人破产制度的呼声越来越高,自然人破产制度的建立已经成为大势所趋。在关于自然人破产制度的具体设计中,侵权之债的破产免责制度仍需要进一步研究。在我国,对于自然人破产中的侵权之债不能当然免责,应采取许可免责;其次,应对侵权之债进行分类,规定哪些可以免责,哪些不可以免责;最后,对于可以免责的侵权之债,应规定为自然之债,仅仅失去强制执行力,而不是必然消灭。     

Physical activity - an important preanalytical variable

The concentration of several biochemical and hematological biomarkers is strongly influenced by a number of preanalytical variables. Several lines of evidence attest that short, middle, and long-term exercise, as well as the relative intensity of physical effort (from mild to strenuous), may influence a broad array of laboratory variables. The amount of extracellular release and clearance from blood of most of these biomarkers is markedly influenced by the biological characteristics of the molecule(s), level of training, type, intensity and duration of exercise, and time of recovery after training. It is hence noteworthy that test results that fall outside the conventional reference ranges in athletes not only may reflect the presence of a given disease, but may frequently mirror an adaptation to regular training or changes that have occurred during and/or following strenuous exercise, and which should be clearly acknowledged to prevent misinterpretation of laboratory data. The aim of this narrative review is to provide an update about the most significant changes of some biochemical and hematological biomarkers in response to physical exercise, for appropriate interpretation of these changes in the context of physically active subjects.     

基于粮食安全与经济发展区域差异的土地资源优化配置——以武汉城市圈为例

从武汉城市圈全局粮食安全的角度出发,综合考虑案例区内各县域经济发展的区域差异,采用灰色预测模型预测的人口总量结合人均粮食消费水平测算得到武汉城市圈耕地需求总量,并运用层次分析法测算各区域建设用地需求优先度,进而构建分区异步元胞自动机模型,可为基于粮食安全与经济发展区域差异的土地资源优化配置提供重要的方法支撑。研究发现,武汉城市圈土地资源区际优化配置结果能满足武汉城市圈粮食安全对耕地的需求,同时也兼顾各区域经济发展水平差异对建设用地的需求。土地资源区域间优化配置须同时考虑全区域粮食安全和经济发展水平的区域差异,为实现土地资源的合理利用和社会经济的可持续发展提供决策支持。     

Resistance training promotes increase in intracellular hydration in men and women

Abstract

The main purpose of the present study was to investigate the effect of 16 weeks of resistance training (RT) on body water in men and women. Thirty men (22.7 ± 4.4 years, 68.4 ± 9.0 kg and 174.5 ± 6.6 cm) and 34 women (22.7 ± 4.1 years, 58.8 ± 11.9 kg and 162.6 ± 6.2 cm) underwent progressive RT for 16 weeks (2 phases, 8 weeks each), 3 times per week, that consisted of 10–12 whole body exercises with 3 sets of 8–12 repetitions maximum. Total body water, TBW (intracellular water, ICW and extracellular water, ECW compartments) and skeletal muscle mass (SMM) were assessed using a spectral bioelectrical impedance device (Xitron 4200 Bioimpedance Spectrum Analyzer). TBW, ICW compartment and SMM increased significantly (P < 0.05) over time in men (+7.5%, +8.2% and +4.2%, respectively) and women (+7.6%, +11.0% +3.9%, respectively), with no sex by time interaction (P > 0.05). We conclude that progressive RT promotes an increase in body water, principally by intracellular content; however, the hydration status is not influenced by sex.     

6周递增负荷运动对大鼠小肠集合淋巴结细胞线粒体凋亡途径的影响

研究6周递增负荷运动对小肠集合淋巴结(PP结)线粒体膜电位(ΔΨm)、BaxmRNA、Bcl-2mRNA和细胞色素C(Cyt C)的影响,探讨PP结淋巴细胞线粒体凋亡途径指标的变化.将64只8周龄雄性SD大鼠随机分为运动组和对照组,运动组进行6周的递增负荷跑台训练,分别于第0、2、4、6周末,利用FQ-RT-PCR技术测定Bax和Bcl-2mRNA的表达水平;利用JC-1染色流式细胞术检测PP结淋巴细胞的平均J-aggregate( FL2)和J-monomer( FL1)的含量,并计算ΔΨm( FL2/FL1);用ELISA法测定Cyt C的浓度.结果显示:(1)6周递增负荷运动过程中,在第2、4、6周,PP结淋巴细胞的ΔΨm显著低于0周,第4周的ΔΨm最低;(2)与0周相比,第4、6周PP结BaxmRNA表达明显增加,Bcl-2mRNA表达降低,Bcl-2/Bax值明显降低;(3)与0周相比,第2、4、6周PP结Cyt C浓度明显增加.结果表明递增负荷运动可能是通过影响线粒体途径从而影响PP结淋巴细胞凋亡的.
