The influence of rain and malathion on the initial oviposition as well as development of blowfly species infesting rabbit carcasses decomposing in sunlit and shaded habitats were studied over a period of 1 year in Kelantan, Malaysia. Chrysomya megacephala (Fabricius) was the most dominant species that infested the carcasses, followed by Chrysomya rufifacies (Macquart). In general, rain, depending on its intensity, delayed initial oviposition by 1–2 days and prolonged the pupation period by 1–3 days. The presence of malathion in the carcasses delayed initial oviposition by 1–3 days and prolonged the pupation period by 2–3 days. These findings deserve consideration while estimating postmortem interval since rain is a commonplace occurrence in Malaysia and malathion is one of the common poisons as an agent for choice to commit suicide. 相似文献

The assessment and diagnosis of posttraumatic stress disorder (PTSD) and depression in forensic evaluations may lack an acknowledgement of the neurocognitive impact of these disorders and how they interact with other causative factors, such as traumatic brain injury (TBI), pain or fatigue. Both PTSD and depression have a complex, growing and consolidating neuroscientific and neuropsychological evidence base, and both can affect neuropsychological test results. In forensic neuropsychological assessments, they are often considered to be confounding factors in evaluating TBI and neurodegenerative disorders but not a source of cognitive impairment in their own right. Yet, an accurate neuropsychological assessment of both cognition and affect is vital to causality determination, prognosis and treatment planning. To complicate matters, selective brain injuries, contingent on the location of injury, can produce symptoms of depression that also affect the neurocognitive profile. Therefore, behavior can overlap not only due to overlapping or comorbid diagnoses, but also due to similar neuroanatomical correlates of both conditions. This paper focuses on reviewing and integrating the available empirical evidence from neuroscience and neuropsychology regarding the cognitive impact of PTSD and depression. Our critical review will emphasize the implications of the more recent evidence for forensic assessment determinations regarding causality, diagnosis, and the impact on function, prognosis and treatment. Hence, electronic search engines, PubMed, PsycINFO, and Google Scholar (up to January 2018) were screened and reviewed both for the neuroscience and neuropsychological literature related to depression and PTSD. 相似文献

Histochemical quantification of the nonspecific esterase (NSE) in injured skin was performed using histochemical demonstration of the enzyme and a microspectrophotometric scanning technique on specimens taken from 32 Hartley guinea-pigs and 8 cases of human skin wounds. In all antemortem incisions and lacerations, including those made at the agonal stage, NSE activity could be observed in the dermal tissue of the wound edge. The enzyme activity increases with the antemortem duration of the injuries. Both total content and mean concentration of NSE in the wound edge between antemortem and postmortem wound groups differ significantly (less than 0.01). Multiple range test shows that significant differences (P less than 0.05 or P less than 0.01) of total content of NSE in the wound edge also exist in 0-5 min, 15-30 min, 1-h, 2-h and 4-h antemortem incised wound groups and in 0-min, 5-min, 15-30 min, 1-h and 4-h antemortem laceration groups. The positive NSE reactions in 8 cases of human skin wounds were similar. The study indicates that histochemical quantification of NSE in injured skin is very useful in timing wounds and is exactly applicable in medicolegal practice. According to the different influences of inhibitors on enzymes, it was inferred that the enzyme activity in wound edges was due to B-esterase. 相似文献

This paper reports on the disaster that occurred after a flight was hijacked at Baiyuen International Airport in Guangzhou, China, on Tuesday, 2 Oct. 1990. The authors show the results of analyses for the causes of death and trauma and compare the disaster with several previous flight accidents that have occurred in China. The authors show, with the analysis on this accident, the possibility and reliability of reconstructing a disaster by medicolegal investigation. 相似文献
