目的研究实验大鼠餐后死亡不同时间段的胃主细胞Kappa-阿片受体(KOR)的表达变化。探讨其变化、表达规律与死亡时间(PMI)的相关性。方法实验雄性大鼠,随机分为对照组和实验组,进食后断颈处死后于不同时间提取组织检材,对组织进行免疫组织化学染色,采用图像分析软件测定阳性面积、积分光密度、平均光密度、平均灰度等参数,用SPSS统计软件对各参数与死亡时间的关系进行相关性分析。结果死后9d内的胃主细胞上Kappa-阿片受体随着死亡时间(PMI)的延长,其积分光密度和阳性面积与死亡时间(PMI)存在一定的相关回归关系。结论实验大鼠死后胃主细胞上Kappa-阿片受体的变化规律与死亡时间有相关性。 相似文献

Costas Douzinas 《The Modern law review》2000,63(6):813-830
Intimate links exist between political power, law and images. Theology, philosophy and law have always developed elaborate rules about visuality. The iconophilic and iconoclastic traditions complemented one another and combined to construct subjectivity and to reconcile humanity with finitude. In modernity, law replaced religion and philosophy conceptualised legality through the aesthetic category of the sublime. The law understands the importance of the governance of images for the maintenance of the social bond and helps organise a regime of permitted images and forbidden idols which amounts to a complex legal administration of aesthetics and a related aesthetic organisation of law. 相似文献

This paper comprises a set of marketing guidelines using the 2000 presidential election as an example, and analysing the image building of the two candidates, Al Gore and George W. Bush. It is not hard to understand, with hindsight, why Bush was the winner. Copyright © 2001 Henry Stewart Publications 相似文献

This article looks beyond Z-score and proposes a novel methodological framework to build an all-encompassing indicator of bank stability for individual banks using the optimisation-based ‘benefit-of-the-doubt (BoD)’ approach. Unlike other available approaches, this approach is totally data-driven and generates endogenous weights to aggregate sub-indicators of bank stability and dimensions. Further, the final outcomes are not limited to a scalar measure of bank stability. The unique optimal weights offer valuable policy-relevant insights and highlight the most precarious areas of stability, which demand the immediate attention of the bank's management and the industry regulators for both micro-and macro-level policymaking. Using the data of Indian public sector banks operating in the year 2018, the study illustrates the proposed framework to obtain a holistic indicator of bank stability, defined on 14 ratio sub-indicators and 5 broad dimensions (soundness, asset quality, profitability, management efficiency, and liquidity) of bank stability. 相似文献

Image interpretation is an important aspect in the field of forensic science; however, it is seldom reported how to use these techniques in explosion scene forensic investigations. On 12 August 2015, a series of explosions killed 165 people and injured hundreds more at a container storage station at the Port of Tianjin. In this study, we applied image interpretation methods to determine the seat of the explosion by analyzing low‐quality video clips of the event. The interpretation fits well with recently published standard operating procedures, including the hypothesis, evaluation, inference, and confirmation. Image processing was adopted to enhance the images while the explosion scene was reconstructed with the same images. Some important features were extracted and utilized to distinguish whether the flashes were caused by reflection or a real blast. We reveal the real explosion location, which guides the overall investigation. The results indicate that image interpretation is a powerful tool for forensic investigators to analyze low‐quality images in complicated explosions or fire accidents. 相似文献

In a previous study, a survey‐based analysis of pathologist diagnoses of patterned injury was performed. Subjects were provided with photographs of “classic” injuries and asked to diagnose the lesion in the absence of history or context. There was a relatively low diagnostic consensus among respondents. A second survey suggested that the disparate answers were not due to a strong belief in different diagnoses, but instead reflected how the respondents dealt with ambiguity. A third survey was created that asked participants to evaluate patterned injuries of the skin, but provided history and contextual information. The addition of history and contextual information increased consensus from a median of 80% to 98% on a per‐question basis. Confidence increased from a median of 56%–92%. These results demonstrate the importance of history and context in medical diagnosis of patterned injuries of the skin. 相似文献

Gender determination is an important step in identification in forensic medicine. CT measurements of maxillary sinuses may be useful to support gender identification. This study was undertaken to study the accuracy and reliability of maxillary sinus dimensions measurement in gender classification through the use of reconstructed helical CT images. Eighty-eight patients (43 men and 45 women) with age range from 20 to 49 years were selected in this study. The width, length, and height of the maxillary sinuses in addition to the total distance across both sinuses were measured. Data were subjected to discriminant analysis for gender using multiple regression analysis. Maxillary sinus height was the best discriminant parameter that could be used to study sexual dimorphism with an overall accuracy of 71.6%. Using multivariate analysis, 74.4% of male sinuses and 73.3% of female sinuses were sexed correctly. The overall percentage for sexing maxillary sinuses correctly was 73.9%. It can be concluded that reconstructed CT image can provide valuable measurements for maxillary sinuses and could be used for sexing when other methods of sexing are not conclusive. 相似文献

在视频图像侦查过程中,经常会发生视频追踪对象在某个特定区域的视频监控图像中"消失"的现象。它可能是由于存在监控盲区造成的,也有可能是由于犯罪嫌疑人的反侦查行为,或者侦查员在视频监控资料收集、处理、查看过程中存在问题造成的。因此,我们可以通过合理布局,减少监控盲区,广泛收集和处理视频监控资料,深入查看和分析视频消失区域,多种侦查手段并用等途径来加以应对。 相似文献

政策变迁并非只是渐进的过程,重大的政策转变和政策中断也时常发生。以逻辑经验主义为基础的渐进主义模型只强调政策的渐进性变迁,而忽略政策的间断性变迁。建立在库恩科学范式基础上的政策研究不仅关注政策的渐进性变迁,而且也关注政策的间断性变迁。"间断-平衡模型"建立在有限理性决策和制度结构基础上,认为政府政策制定具有稳定性和间断性的特点。该模型有效解释了长期政策稳定过程中伴有偶尔急剧变迁的现象,为长期政策变迁提供了新的解释框架。本文介绍了"间断-平衡模型"的缘起、理论基础、核心观点、解释过程等几个方面,最后对模型进行简要评述。 相似文献
