Lesions of the brain stem and cerebellum due to nutritional deficiencies are mostly seen in chronic alcohol abuse and more rarely in severe malnutrition. We report the case of a 27-year-old woman, found dead in the family flat. She presented cachexia (167 cm, 25 kg) and multiple hematomas of the limbs. Postmortem examination revealed lesions due to peritonitis. Neuropathological examination showed severe atrophy of the corpus callosum and central neuronal chromatolysis, which are observed in pellagra. Inflammatory colitis or celiac disease was not found. Toxicological analysis was negative, in particular no alcohol absorption. Pellagra, which is due to nicotinamide deficiency, is a disease rarely seen in this country. In this case, nutritional deficiency was the consequence of failure to eat in a context of abuse. The woman was born of an incestuous relationship and presented intellectual retardation due to poor affective relations with her mother.  相似文献

Preparation of degraded human DNA under controlled conditions   总被引:7,自引:0,他引:7  
DNA typing through analysis of short tandem repeats (STRs) and mitochondrial DNA (mtDNA) by means of the polymerase chain reaction (PCR) and sequencing are the common methods for the forensic identification of persons and reconstruction of kinship, especially when skeletal human remains have to be analyzed. Furthermore, samples typically found at crime scenes may be both quantitatively and qualitatively inadequate since they may contain very scarce and often degraded DNA due to exposure to heat, light, humidity, and microorganisms. In order to improve the performance of STR typing technology in those cases where DNA availability is limited, it would be desirable to have a source of degraded DNA with known properties. For this purpose, we have developed a method to prepare artificially degraded DNA under controlled conditions. By treatment of genomic DNA with sonication and DNAse I we have produced DNA fragments within a defined range of lengths. STR typing of this degraded DNA with a commercially available multiplex kit could only produce partial profiles as indicated by the absence of STR alleles with sizes >200 bp. This artificially degraded DNA can be used for the improvement and standardization of STR typing protocols when only highly degraded DNA is available for analysis.  相似文献

Domestic violence (DV) is a pattern of behaviors in the context of an intimate relationship, which can be manifested in emotional, physical, or sexual abuse. DV currently represents a social and a public health issue. This study is an effort to foster a better understanding of DV among same-sex couples. In it, the authors included the participation of 199 Puerto Rican gay males to identify prevalence of DV, violence in their family of origin, participants' addictive behaviors and exposure to violence at childhood, and their conflict resolution skills. Participants were relatively young, highly educated Puerto Rican gay men who reported a high level of domestic violence in their relationships. This violence was identified as emotional violence by 48% of the participants. This sample reported high levels of violence among their families of origin and low conflict resolution skills.  相似文献

Inductively coupled plasma mass spectrometry (ICP-MS) was used to analyze glass evidence from a case in which a person broke a window in each of 15 vehicles in a parking lot in order to gain entry into the vehicles. The results of the analysis by traditional methods, which measure the properties of color, thickness, density, and refractive index, are also reported. A total of 15 known samples representing the windows on the cars and 42 questioned glass fragments recovered from the suspect and the police vehicle where the suspect was sitting were submitted for analysis. Density comparisons separated one of the known samples into three samples, increasing the number of known samples from 15 to 17. The concentrations of 16 elements were measured for all but three of the samples using an external calibration ICP-MS method with internal standardization. Color assessment (non-instrumental) separated the 17 known samples into two groups, and refractive index measurements resulted in six groups when the Emmons double variation method was used and ten groups when the Glass Refractive Index Measurement 2 (GRIM2) system was used. Elemental analysis, by itself, differentiated all of the known samples from each other and associated four of the known sample fragments with several of the questioned sample fragments. The informing power of RI, density, and elemental analysis comparisons is evaluated and a summary of the case results is reported.  相似文献

A new Windows-based freeware for kinship analysis from DNA data is presented. This software can be used to calculate likelihood ratios and probabilities of paternity in trio and motherless cases, as well as in cases when a parent is lacking but there are data from the grandparents. It can also be used to compute the probability of two subjects being full-brothers or half-brothers.  相似文献

Although not its sole dimension, the idea of equality of rights and resources is one of the basic tenets of liberalism. Liberal equality introduces a reformist thrift in government by determining that government action should aim to create opportunities for the realization of the civil condition. This is a legal and political condition, thereby citizens enjoy a statute of equal rights. Hence, the liberal idea of reformism proceeds by removing the obstacles to the realization of the civil condition and by providing the legal and the material resources for the exercise of citizenship rights. This interpretation is not self‐evident, especially in times when neoliberalism seems to represent the entire liberal tradition. I shall argue that liberal reformism makes up a vital foundation for democracy. Even more, the own survival of democracy in our times depends on its rooting in liberalism.  相似文献

Trust in government is foundering. Ethics codes have limited utility in bolstering public trust, and a clear correlation between such codes and changed behavior must still be established. They are a means for external oversight, but they do nothing in terms of providing an internal moral compass. To rebuild trust in government, employees must also act with integrity. Actions that are both ethical and carried out with integrity are necessary—neither is sufficient. Acknowledging this, the Dutch Tax Administration undertook a two-pronged approach focused on the management of integrity as a means to codify the operational ethics of the organization, as well as to foster shared values and behaviors. This approach is noteworthy because it guides behaviors while retaining street-level discretion. It also is the first step toward creating a bureaucracy of mutual relationships that creates an ongoing moral consciousness serving both democracy and efficiency not only through control, but also through self-reflection, interaction, and association.  相似文献
