A series of validation experiments was performed for a Y chromosome specific STR multiplex system following the suggestions made by the Technical Working Group DNA Analysis Methods (TWGDAM). The multiplex PCR products were detected on Perkin-Elmer 373 and 377 automated sequencers using two labeling colors. No problems regarding the stability, robustness and sensitivity of the Y STR multiplex were observed. Mixture studies revealed a cut off rate similar to autosomal STRs for mixtures of male DNAs and no interference of any female admixture. The comparison of the Y STR results to the autosomal typing results for 56 nonprobative semen stains and swabs, showed a slightly higher success rate in detecting the semen donor's alleles for the Y STR multiplex. Two examples are shown to illustrate the usefulness of Y STR typing for DNA mixtures. In one case the Y STR results confirmed an isolated exclusion; in the other case, the interpretation of a mixture was clarified since the Y STR results proved the presence of DNA from at least two semen donors. Y STR typing is a valuable addition to the forensic DNA testing panel.  相似文献

Zusammenfassung  Die europarechtlichen Normen des sog. individuenbezogenen Artenschutzes (insbesondere Art. 5 lit. a Vogelschutz- und Art. 12 Abs. 1 lit. a FFH-Richtlinie) sowie die innerstaatlichen Umsetzungsnormen in § 42 Abs. 1 BNatSchG sind entgegen einer weit verbreiteten Tendenz als Verbote bestimmter gezielt auf individuelle Exemplare der geschützten Arten gerichtete Zugriffshandlungen ernst zu nehmen. Der Beitrag zeigt auf, wie auf dieser Basis der ausufernden Anwendung der genannten Normen vorgebaut werden kann. Die abgestufte Handlungsverantwortlichkeit von Verkehrsteilnehmern, Beh?rden zur ordnungsbeh?rdlichen Regelung des Verkehrsgeschehens sowie zur Zulassung von Verkehrsanlagen und -wegen wird verdeutlicht, zugleich ein praktikabler Weg zum ma?vollen und differenzierten Umgang mit dem besonderen Artenschutzrecht aufgezeigt.  相似文献

Normal adrenocortical activity is necessary for electrolyte regulation and the maintenance of cardiovascular function. Although chronic adrenal insufficiency generally presents with the gradual onset of a set of characteristic symptoms and signs, the more sudden loss of adrenal activity can present with acute, rapidly progressive cardiovascular dysfunction that can be fatal if not recognized and treated promptly. We herein describe a patient who had most of his adrenal tissue removed during resection of metastatic renal carcinoma, conventional clear cell type, with much of the remaining adrenal tissue undergoing necrosis during or shortly after surgery. Although the patient appeared to be stable and progressing adequately well, he died suddenly 2 days postoperatively. When the gross autopsy findings suggested the possibility of adrenal insufficiency, clinical laboratory assessment of adrenocortical activity was sought. Analysis of stored antemortem serum samples and of blood obtained at autopsy demonstrated a progressive decrease in cortisol levels which, in this stressed postsurgical patient, proved fatal. The use of both antemortem and postmortem blood in the demonstration of acute adrenal insufficiency at autopsy is discussed.  相似文献

Sudden fatal cases of influenza B infection in a 4-year-old girl and a 2-year-old boy are presented. Both children complained of abdominal pain without respiratory, neurologic or cardiac symptoms; additionally the girl had vomiting within 2 days of death. Autopsy revealed histological changes in the respiratory system consistent with a viral infection. Influenza B infection was identified by immunohistochemistry in the girl and real-time polymerase chain reaction in the boy. Additional testing including cultures, toxicology, and screening for metabolic disorders were negative. These cases illustrate the usefulness of viral testing, especially for influenza, in the medical legal autopsy of children even when the classic respiratory symptoms of flu are lacking.  相似文献
