用透射电镜观察了紫彩血蛤(Nuttallia olivacea)的肾脏和围心腔腺的超微结构.在肾脏中观察到4种细胞:具液泡的立方形细胞、具液泡的长柱形细胞、吞噬细胞和肌细胞.在围心腔腺中观察到3种细胞:柱状上皮细胞、实质细胞和吞噬细胞.肾脏中除了肌细胞外的3种细胞及围心腔腺中除了柱状上皮外的2种细胞内均有色素颗粒,它们能将色素颗粒转化降解.  相似文献

后殖民主义理论家霍米.巴巴主张运用混杂策略消解西方殖民主义者的文化霸权,提倡构建一个居间的"第三空间"。此理论对少数族裔在美国主流社会进行身份定位有着重要意义。著名美国华裔作家汤亭亭在其成名作《女勇士》中对中国传统典故的移植和改写可以认为是一种积极的写作策略,意在消解文化二元对立状态,从而建构一种"居间"的文化身份。  相似文献

当前我国法制建设在制度移植与重生方面面临着一种困境,即法制建设究竟是应该整理传统以利用本土资源并进而实现传统的创造性转化,还是应该以西方制度演化史所积淀的现代法制模式为榜样进行整体或局部的法律移植,学界对此亦存在相当的论争。然而值得怀疑的是,这些不同角度的理论进路究竟在多大程度上能给当前的困境提供一种出路,甚而有学者以为当前的制度变革本就无解。  相似文献

Objectives: Metabolic syndrome (MtS) and kidney stone are two common aging diseases with male dominant. This is the first study regarding the potential impact of MtS and its components on kidney stone in aging Chinese population.

Methods: A total of 694 males with a mean age of 55.6 years were enrolled. The definition of MtS was according to the modified criteria developed by the Bureau of Health Promotion in Taiwan. Subjects were classified as having a disease of kidney stones according to diagnosis by a physician with available medical records or evidence from ultrasonography judged by an investigator of urologist.

Results: Using age-adjusted multivariate logistic regression analysis, our results showed that subjects with kidney stone had significantly higher prevalence of MtS (p?=?0.04, OR?=?1.74, 95% CI: 1.0 1–3.00). The presence of MtS had significant correlation with kidney stone (p?=?0.01, OR?=?1.83, 95% CI: 1.1 4–2.93), which were associated with the increment of MtS components (p?p?Conclusions: In aging Taiwanese males, the presence of MtS and its components are strongly associated with kidney stone. Abnormal BP is the most significant risk component of MtS for kidney stone.  相似文献

Owing to the worldwide shortage of deceased‐donor organs for transplantation, living donations have become a significant source of transplant organs. However, not all willing donors can donate to their intended recipients because of medical incompatibilities. These incompatibilities can be overcome by an exchange of donors between patients. For kidneys, such exchanges have become widespread in the last decade with the introduction of optimization and market design techniques to kidney exchange. A small but growing number of liver exchanges have also been conducted. Over the last two decades, a number of transplantation procedures emerged where organs from two living donors are transplanted to a single patient. Prominent examples include dual‐graft liver transplantation, lobar lung transplantation, and simultaneous liver‐kidney transplantation. Exchange, however, has been neither practiced nor introduced in this context. We introduce dual‐donor organ exchange as a novel transplantation modality, and through simulations show that living‐donor transplants can be significantly increased through such exchanges. We also provide a simple theoretical model for dual‐donor organ exchange and introduce optimal exchange mechanisms under various logistical constraints.  相似文献

论法律继承     
一个民族的存在必以其历史为基础。一个民族的法律只有与该民族的历史相沿承、与其本土资源相适应才能存活。法律现代化的口号喊得再高、再响,使法律与本土资源相适应终是其根本途径。在我国,法律移植轰轰烈烈地进行了近百年,结果并不尽如人意,最终还是不得不把目光投向对历史的继承上来。本文以重新探索法律现代化路径之选择,检讨法律移植之得失,审视历史沿续的不可避免为出发点,以社会的法律和社会的文化之一致融合为落脚点展开探讨。  相似文献

"新时期"以来以马原和余华为代表的先锋叙事大大推进了中国小说叙事的现代化进程.但是这种"推进"实际上具有的仅仅是"移植"的价值,真正的中国小说的叙事革命并未到来,因为这种"革命"的本质乃是创新.而由于中国现今特殊的国情,这种创新已经无法从西方现代小说的移植中培养,所以,"中国本土化叙事革命"也就成了我们热切的前景期待.  相似文献

Multi-state models (MSMs) are useful to analyze survival data when, besides the event of main interest, one or more intermediate states of the individual are identified. These models take the several existing states and the possible transitions among them into account. At the same time, covariate effects on each transition intensity may be investigated separately and, therefore, MSMs are more flexible than the standard Cox proportional hazards model. In this work, we use MSMs to investigate the impact of the quality of a transplanted kidney for a group of patients at the Hospital Universitario Central de Asturias. Specifically, we use an illness-death model to study the evolution of patients with kidney disease who received a renal transplant after a dialysis period. The intermediate state is defined as the failure of the received organ, while the terminating state is the death of the patient. In order to increase the potential number of organs available for transplant, the standards of quality for the transplanted kidneys were relaxed (the new criteria are labeled expanded criteria), and these ‘expanded kidneys’ were transplanted in appropriate candidates (older patients, with higher prevalence of diabetes mellitus). Results suggest that the expanded kidneys have a minor effect on survival, while both the kidney mortality and the risk of death increase with the patient's age and the serum creatinine and serum hemoglobin levels.  相似文献

原始佛教法是由佛陀所制定并且为世俗法所承认的,原始佛教规范具备法律要素,既有内部立法权,也得到了世俗统治者的承认,是“未完备世界”的法律,而中国佛教法的效力渊源来自于两部分,一是佛教内部立法权的确立,此为佛教法立法权的继承,主要是“适宜”规则的运用。二是世俗政权的承认。  相似文献
