The polymorphism of BF was investigated in 765 unrelated Japanese individuals by isoelectric focusing and immunoblotting. Besides five common subtypes three rare variants were observed. The allele frequencies were: BF*S = 0.8078, BF*FA = 0.1797, BF*FB = 0.0105, BF*Var. = 0.0020. The above method was successfully applied to subtyping BF in stored bloodstains. The determination limits were: at 4 degrees C 8 weeks, at room temperature 2 weeks and at 37 degrees C only 2 days after storage. The BF subtyping is of practical use in medicolegal individualization of unknown bloodstains. 相似文献

Identification of fetal bloodstains by enzyme-linked immunosorbent assay for human alpha-fetoprotein
Y Katsumata M Sato K Tamaki H Tsutsumi S Yada M Oya 《Journal of forensic sciences》1985,30(4):1210-1215
A rapid and highly sensitive enzyme-linked immunosorbent assay (ELISA) for determination of human alpha-fetoprotein (AFP) using commercially available reagents was devised and applied to identification of fetal bloodstains. When experimentally prepared bloodstains, 1 by 2 mm in area, were submitted to analysis, only fetal bloodstains showed positive reactions in the present ELISA. The reactions did not change significantly when these bloodstains were stored at room temperature for one week. The present ELISA seems to be suitable for forensic science practice. 相似文献

In the past decade, Guangzhou (Canton), China, has produced mixed results in water pollution control: it has been successful in limiting pollution from industrial sources than from domestic ones. This article examines the case by reference to a growing body of literature in institutional analysis. The central arguments are that institutions affect the governance and management of natural resources by allocating decision-making authorities among different individuals, agencies and levels of governments, by affecting whether rules and regulations can be effectively enforced and by creating different incentive structures. These arguments help to explain the divergent governmental efforts and outcomes in the two types of water pollution control in Guangzhou. The article concludes by discussing the case's theoretical and practical implications. 相似文献

To determine the cause of death (as a result of neurologic or nonneurologic complications or accidents) in patients with multiple sclerosis (MS), we reviewed the autopsies of 50 subjects with MS from the Office of the Chief Medical Examiner of Maryland (OCME) between 1982 and 2004. The series included 32 females and 18 males (mean age, 45.8 years; range, 25-69 years) and the causes of death were classified into 3 categories: (A) neurologic complication directly related to MS; (B) nonneurologic complications or other medical causes; and (C) accidents, etc. Of the 50 cases, in 43 there was a history of MS, but in 7 subjects there was not, and the diagnosis was established by neuropathologic examination. In Group A, 21 (42%) cases, deaths were directly related to a neurologic complication; in Group B, 14 (28%) cases were related to the following nonneurologic and medical causes: ASCVD 9 (18%), metabolic disorder 1 (2%), pulmonary embolism 3 (6%), and bronchopneumonia 1 (2%); and in Group C, 15 (30%) cases, deaths were due to trauma, 9 (18%); intoxication, 5 (10%); and thermal injury, 1 (2%). Thus, among the 50 subjects, in 26, deaths occurred naturally; and in 24, from accidents, homicides, suicides, or undetermined causes. Pathologically, the majority of cases showed either chronic inactive (66.7%) or chronic active (15.6%) demyelinating lesions, mainly in the cerebral hemispheres. In some cases, it appears that demyelinating lesions, involving brain regions that regulate cardiorespiratory activity, could be considered as the immediate cause of death, but a large proportion appears to be due to other causes such as accidents and trauma. Thus, it seems likely that taking specific precautions could prevent some deaths in MS. 相似文献
