The aim of our study was to investigate the postmortem levels of glucose and glycogen in hepatic, renal, muscle, and brain tissues and then examine the changes in those levels that could be useful for estimating postmortem interval. We established an animal model. Seventy female BALB/c albino mice were used in this study. After being sacrificed, the mice were randomly divided into six groups according to time elapsed since death (Group 1: 0 h; Group 2: 12 h; Group 3: 24 h; Group 4: 36 h; Group 5: 48 h; and Group 6: 60 h). Glucose levels were significantly different between groups for all tissues studied. Slope of the change per unit time was higher for the hepatic glucose levels. Based on these results, it is possible to estimate postmortem interval using postmortem glucose levels in hepatic tissue. Tissue‐specific assessment may contribute valuable information to postmortem interval studies.  相似文献

During the Korean War, the Office of the Quartermaster General's Graves Registration Service (GRS) was responsible for the recovery, processing, identification, and repatriation of US remains. In January 1951, the GRS established a Central Identification Unit (CIU) at Kokura, Japan. At the Kokura CIU, postmortem dental examinations were performed by the dental technicians. Thirty‐nine postmortem dental examinations performed at the CIU were compared to the findings documented in the Forensic Odontology Reports written at the JPAC Central Identification Laboratory (CIL). Differences were noted in 20 comparisons (51%). The majority of the discrepancies was considered negligible and would not alter the JPAC decision to disinter a set of unknown remains. Charting discrepancies that were considered significant included the occasional failure of the Kokura technicians to identify teeth with inter‐proximal or esthetic restorations and the misidentification of a mechanically prepared tooth (i.e., tooth prepared for a restoration) as a carious surface.  相似文献

This study presents a novel means of rapidly determining benzodiazepines in various drinks. Electrospray mass spectrometry with a direct probe design is used as the analytical instrument. Samples are treated only by a simple liquid-liquid extraction prior to direct electrospray probe/mass spectrometry (DEP/MS) analysis. The proposed method provides a relatively easy and efficient means of identifying the drugs in a very short time interval. On average, sample analysis is completed in less than five minutes including sample pretreatment. It is especially useful in forensic science since the technology can provide a rapid identification for unknown samples. Thus, the method proposed herein is highly appropriate for rapidly screening a large number of samples.  相似文献

There is widespread criticism of the behaviour of junior officials in post-communist Europe where they are often accused of treating citizens unfairly and soliciting presents or bribes to solve citizens' problems. To get the perspective of officials themselves we interviewed 1307 junior officials and state employees in Ukraine, Bulgaria, Slovakia and the Czech Republic. This paper focuses on their willingness to accept gifts from clients, their confessions to having done so, and the factors that lead some officials to accept gifts while others do not – factors such as occupational bargaining power and the (related) frequency of offers from clients, economic pressures, national and institutional cultures, fear of punishment, and moral perspectives on charging clients for favours. Economic pressures make officials more inclined to feel that they 'could not afford to refuse' gifts, but this motivation is only weakly related to actual behaviour. Occupational bargaining power and the frequency of offers from clients make them more likely to 'welcome' gifts or accept them 'out of politeness'– and these less excusable motivations are more strongly related to actual gift-taking.  相似文献

Although the past decade has witnessed the rise of studies on Chinese evaluations of the police, rural villagers’ assessments of the police remain under-researched. Drawing upon performance theory and survey data from China’s countryside, this study tested whether variations in satisfaction with government performance and life are linked to villagers’ and officials’ trust in county and local/town police. We found that villagers displayed lower levels of trust in the police than local officials. Higher satisfaction with government performance and integrity were associated with greater trust in county police among both villagers and officials. Villagers’ greater satisfaction with crime control and safety led to their stronger trust in both county and town police, but such satisfaction was not significantly related to officials’ trust in both levels of police forces. Rural residents’ generalized trust and particularized trust were associated with a greater likelihood of viewing the police as trustworthy. Meanwhile, female respondents, both villagers and officials, and higher-income officials were more likely to view the police as trustworthy. Directions for future research and policy are discussed.
