The genetically determined polymorphism of alpha 2 HS-glycoprotein was analyzed by immunoblotting ultrathin-layer polyacrylamide gel isoelectric focusing in the pH range 4-6.5 and neuraminidase pretreated sera. In a Libyan population sample from Tripoli (n = 110) three common phenotypes, alpha 2 HSG 1-1, 2-1, and 2-2, were observed. The allele frequencies were alpha 2 HSG1 = 0.8364 and alpha 2 HSG2 = 0.1636. The theoretical exclusion rate in cases of disputed paternity is 11.8%. 相似文献

With the Comprehensive Anti-apartheid Act of 1986, Congress instituted economic sanctions against South Africa, thereby reversing the historic course of U. S. foreign policy. This political innovation constituted a great victory for minority interests. This article utilizes the agenda-setting literature to examine the relationship between Anti-apartheid movement activity in the United States and adoption of economic sanctions against South Africa. The analysis is based upon an events data set consisting of 1353 events appearing in the New York Times between 1960 and 1986, interviews with activists and legislators, and archived materials. The ar- ticle concludes that although the Anti-apartheid movement was only in- directly involved in moving sanctions legislation to the policy agenda, the movement exerted direct influence in the policy process once the legislation had agenda status. 相似文献

The paper gives the results of tests for influence of luminol solution of different composition on detectability of haptoglobin fractions in the bloodstains of different ages. It was stated that alkaline luminol solutions reduce intensity of fractions and may hamper Hp phenotype determination especially in old stains. 相似文献

Asbestos, a fibrous mineral, has unique physical and chemical properties, including resistance to heat, acids, and other chemicals; flexibility; and great tensile strength. The fibers subdivide into unit fibrils of molecular dimensions, resulting in a vast mineral surface area which has a direct bearing on its unusual features and its numerous applications. Its biological effects, which include fibrogenesis and carcinogenesis, may be related to the cellular reaction, to its large specific surface, or to the size and shape of the fibers. Its oncogenic action may be multiplied by other carcinogens, principally cigarette smoking. There is clinical, pathologic, and epidemiologic evidence that exposure to asbestos, following a long latent period, constitutes an important health hazard. Direct occupational exposure, followed by a long lapsed period after the initial exposure, is associated with pleural plaques and pleural effusion, pulmonary parenchymal fibrosis (asbestosis), pulmonary carcinoma, pleural and peritoneal mesothelioma, and other neoplasms. Indirect exposure may also entail an increased risk of lung disease or mesothelioma or both. Medicolegal investigation of suspected cases includes a lifetime occupational history, clinical history including smoking habits, radiological findings, clinical evidence of asbestosis, and may require detection of asbestos tissue burden. 相似文献

Misidentification syndromes or phenomena are found in a number of psychiatric situations that may become the subject of forensic science review. One of the most curious is misidentification of self in which the individual perceives himself or herself as another being while able to explain the loss of the original identity. Recognizing these phenomena may be helpful in accurate diagnosis, in considering such conditions as psychosis of whatever type, multiple personality disorder, and other amnesia and fugue states, and in understanding the person's psychopathology. Two cases are presented to illustrate a process that the authors have named the Riel Phenomenon, after the person who was a party to what is often recognized as the most famous case in Canadian history. 相似文献

In order to find methods applicable for disclosing electrical torture, pig skin was exposed to heat and electricity under controlled circumstances. Biopsies were obtained immediately after exposure and the morphology of the heat lesions was compared to that of electrical lesions. The cytoplasm of epidermal cells in heat lesions appeared granular or fibrillar, while the nuclei were rather unaffected. In electrical lesions the cytoplasm appeared homogeneous often with a peculiar white colour in hematoxylin-eosin stained sections. The nuclei were either dark and shadowy or enlarged and vesicular. The keratin in electrical lesions often showed a bright yellow colour. Small defects in the epidermis were seen in some electrical lesions. Thus the morphology of electrical lesions differed markedly from that of heat lesions. Although some of these differences may be due to differences in distribution and intensity of energy, it is probable that pH shifts in the cells due to electrolysis is the main cause of the specific morphology of electrical lesions. 相似文献
