目的探讨小鼠皮肤切创愈合过程中损伤区磷酸化p38MAPK(p-p38MAPK)的表达情况,以及不同损伤时间p-p38MAPK的变化规律。方法应用免疫组织化学和Westernblot的方法检测33例小鼠皮肤切创后各个时间段p-p38MAPK表达情况。结果正常组织中有少量的p-p38MAPK表达。伤后3~12h损伤区p-p38MAPK主要表达于中性粒细胞中,1~5dp-p38MAPK阳性表达主要为单核细胞和成纤维细胞。7~14dp-p38MAPK阳性表达主要以成纤维细胞为主。阳性细胞率3~12h逐渐升高,1d有所下降,3、5d阳性细胞率保持在高水平,7~14d阳性细胞率逐渐降低。Westernblot显示各个时间段均有p-p38MAPK的表达。其中12h和3d为2个p-p38MAPK含量的高峰。结论在小鼠切创愈合过程中p-p38MAPK在损伤区对诱导中性粒细胞、单核细胞和成纤维细胞的凋亡起重要的作用,同时p-p38MAPK的规律性表达可用于损伤时间的推断。 相似文献

The aims of this study were to investigate the sex discriminating potential of the talus in Koreans and compare this with other analyses in different populations. Statistical analyses were performed using data from nine measurements acquired from 140 tali (70 men, 70 women). The talus of Koreans is dimorphic between sexes in all measurements (p < 0.01). Discriminant function equations were generated by univariate, multivariate, and stepwise methods with a range of accuracy from 67.1 to 87.1%. Stepwise equations of other populations did not discriminate the sex of the Korean sample as accurately as each equation's own accuracies. The variables with high accuracy in this study are useful for sex determination of Koreans on the basis of confirmation of population specificity. 相似文献

Reverse projection photogrammetry has long been used to estimate the height of an individual in forensic video examinations. A natural extrapolation would be to apply the same technique on a video to estimate the speed of an object by determining the distance traveled between two points over a set amount of time. To test this theory, five digital video recorders (DVRs) were connected to a single fixed camera to record a vehicle traveling down a track. The vehicle's speed was measured through Doppler radar by a trained operator and the speedometer of the vehicle was also recorded with a video camera. The recorded video was examined and the frames that best depict the beginning and end of the vehicles course were selected. Two reverse projection photogrammetric examinations were performed on the selected frames to establish the position of the vehicle. The distance between the two points was measured, and the time elapsed between the two points was examined. The outcome provided an accurate speed result with a standard degree of uncertainty. This study proves the feasibility of using video data and reverse projection photogrammetry to determine the speed of a vehicle with a limited set of variables. Further research is needed to determine how additional variables would impact the standard degree of uncertainty. 相似文献

诚实推定权由纳税人财产权与人格尊严权衍生而来,在立法中加以确认有助于落实税收法定、践行量能课税和提高纳税人遵从度。诚实推定权借鉴了刑法上的无罪推定和民法上的善意推定,其基本内涵是税务机关认为纳税人有少缴税款嫌疑时,应由该机关承担举证责任,证明强度应达到优势证据标准。我国应在修改《税收征收管理法》时,明确表达纳税人享有诚实推定权,同时准确界分纳税人的协力义务和税务机关的举证责任,强调逃税行为必须具备主观故意的要件,合理限定税收检查权。诚实推定权入法将对税收征纳实践产生影响,提高现有“计税依据明显偏低”的认定标准,使纳税人的正当理由诉求更有可能被认可,对逃税行为的界定也将更为精确。 相似文献

Key to the success of peacebuilding and social reconstruction in the former Yugoslavia are the attitudes of these young people. Our goal in this paper is to explore young people’s attitudes about the prospects of reconciliation vis-a-vis those with whom their nations were formerly at war. In particular, we examine three sets of factors. First, we contend that the level of contact among people engendered by the segregated educational systems affects the attitudes of the young about the possibility of reconciliation. We suggest that those who are able to interact more frequently with fellow students from other ethnic groups will be more likely to believe in the possibility of reconciliation. Second, we contend that attitudes of young people about which ethnic groups were responsible for the violence in the former Yugoslavia and the efforts of the international community to bring truth and justice will strongly influence attitudes. Finally, we examine other factors such as education and the influence of gender on reconciliation. 相似文献

The lecture examines the role and objectives of truth and reconciliation commissions in societies undergoing major political transitions, with particular reference to the model of South Africa, and compares this method to others suggested by international criminal law for accommodating both retributive and restorative responses to past conflicts and crimes against humanity. 相似文献

Although insurgencies may begin their rebellions with expressed desires for outcomes unacceptable to opposing governments, the desired insurgent outcomes sometimes undergo modification, creating conditions that can make governments more amenable to external mediation. In certain separatist conflicts, the likelihood of external mediation increases when the political redefinition of the state insisted upon by the insurgents undergoes a revision, from secession to self‐determination, understood as a variant of autonomy. In the same vein, although it may not happen concurrently, insurgent movements become more amenable to external mediation if and when opposing governments revise the preferred conflict outcome from a military defeat of the insurgents to a containment of the movement. These two developments can serve as objective referents helping external parties to identify a ripe moment in the conflict and initiate mediation. But the implementation of an agreement ending separatist conflict may not occur if the government fails to submit the proposed territorial bounds of autonomy to prior review by constituents. Potential spoilers among government constituents should be identified and recruited to participate in the negotiations so that the likelihood of agreement rejection is reduced. In some states, however, the legal mechanisms and political opportunities for constituents to act as spoilers do not exist. 相似文献
