Isoenzyme band patterns of animal blood erythrocyte acid phosphatase (EAP) and phosphoglucomutase-1 (PGM) were studied by isoelectric focusing on ultrathin polyacrylamide gels. For blood from all animals tested (dog, cat, cow, sheep, and goat), the overall band patterns for both isoenzymes were different from those of the most common human types of these enzymes, although some animal EAP and PGM bands appeared in the human band areas. When mixtures of human and animal red blood cells were studied, it was found that misinterpretation of human types was possible only if the overall band pattern of the mixtures was ignored. For the animal blood tested, the strong PGM bands appearing outside the human band areas could be used as "markers" for the possible presence of animal blood in the samples tested.  相似文献

Programme based on mathematical model of the process of dead body temperature changing was developed for estimation of postmortem interval. Automatic retrieval of problem solution was performed on programmable microcalculators of "Electronica MK-61" type using adaptive approach. Diagnostical accuracy in case of dead body being preserved in permanent cooling conditions is +/- 3%.  相似文献

So far, the law in the Federal Republic of Germany still allows the injection of fresh-cell preparations from animals as a roborant to increase the vitality of the organism and to strengthen the body's immune defense system. The use of "sicca-cell" preparations was provisionally forbidden in 1987 by the Federal Health Organization (Bundesgesundheitsamt; BGA). Prohibition of fresh-cell injections would have exceeded the authority of this office, although the same serious reservations also applied in the case of this treatment method. Several publications that have appeared since 1955 have reported serious complications of this therapy, some life-threatening and some even lethal. Two further cases are now added: (1) A woman aged 69 had been receiving treatment with cell injections for 9 years. Immediately after an injection of sicca cells she collapsed and was hospitalized; 7 days thereafter she developed an ascending paralysis with increasing inability to swallow or breathe. She died 25 days after the injection as a consequence of central and peripheral respiratory failure. Autopsy revealed the alterations typical for acute Landry-Guillain-Barré-Strohl syndrome. (2) A 76-year-old healthy woman had been receiving treatment with fresh-cell preparations for several years. After an injection of cell suspensions a painful local swelling was observed. The symptoms were interpreted as the consequence of an iatrogenic local hematoma, and repeated punctures were performed to obtain blood. The patient was transferred to a surgical department for further therapy. Two days after the injection she suddenly died with signs of acute cardiovascular failure. Autopsy revealed the signs of a fulminating clostridial infection and also the characteristic signs of Landry-Guillain-Barré syndrome with involvement of the autonomic nervous system. In both cases the development of an inflammatory process in the peripheral nervous system could be interpreted as an immune-mediated allergic disease, related to the repeated injection of heterologous antigenic material containing nervous tissues. This hypothesis would also explain the two other cases already published and would be consistent with the observed perivenous leukoencephalopathy of the central nervous system. The human disease pictures correspond to the well-established animal models of EAEM (experimental allergic encephalomyelitis) and EAN (experimental allergic neuritis). The pathogenesis is discussed; the major role of the central and peripheral nervous system is stressed, with special reference to the risk of acute autonomic failure. The need for specific autopsy techniques for the investigation of the entire nervous system, including spinal cord, roots, spinal ganglia and peripheral nerves with sympathetic chains, is raised.  相似文献

This brief opposes the overturn of "Roe v. Wade" and resists weakening "Roe's central holding" that would allow states to overturn legal abortion. The brief was written for 885 law professors. "Roe" was not a "constitutional aberration," or "an exercise of raw, judicial power." Some members of the Supreme Court seem to think that the state has "an overriding interest" in protecting fetal life. Some Court members have questioned "Roe's" trimester framework. A person's decision to abort should be done privately. If women are not free to choose abortion, they will not have equality. There is an absence of "express rights of privacy and procreational freedom" in the Constitution. "Roe" was 1 instance of the Court's recognition of constitutional rights that are not named explicitly. Historical materials are drawn on to show the link between trends in society and the "judicial recognition of unenumerated rights." The most serious questions about "Roe" deal with its trimester framework. Justice Blackmun's majority opinion said that the 1st trimester of pregnancy was personal. "Roe" said that abortions created a medical risk at the beginning of the 2nd trimester. Therefore, the government was more interested in the health of the mother at that time. The state could then regulate abortion "in ways that are reasonable related to maternal health." The start of the 3rd trimester was when the fetus was viable. The right of a woman to end her pregnancy "offends powerful moral forces." Some of "Roe's" critics had their scientific facts wrong. Medical authorities think Justice O'Connor is mistaken when she says that "Roe" is "on a collision course with itself." The 23rd to 24th week of pregnancies where the fetal organs can "sustain life outside the womb." This has not changed since "Roe" was decided in 1973, nor is it likely to in the future. Some "amici" believe that the state can never have an interest in the fetus. The state can not have an interest in the fetus distinct from the woman who will give birth to it. During previability, restricting a woman's procreational rights would not be scientifically supportable. The state does have an interest in "upholding the value of human life." "Roe" is "within the mainstream" of constitutional jurisprudence and should be reaffirmed.  相似文献

Empathy is defined as an affect more appropriate to another's situation than to one's own. The paper (i) summarizes different modes of empathic affect arousal; (ii) shows how empathic affect may interact with social-cognitive development, to produce four levels of empathy development; (iii) suggests that causal attributions may transform empathic affect into sympathy, guilt, and empathic anger, which are major moral affects; (iv) discusses how these affects may influence moral judgment and behavior; (v) points up empathic morality's limitations and the need to embed empathy in relevant moral principles; (vi) discusses possible links between empathy and justice principles, with special focus on Rawls; (vii) illustrates the interplay of empathy, moral judgment, and justice; and (viii) suggests that moral principles may become hot cognitions.  相似文献

A precise method for evaluating election schemes   总被引:1,自引:0,他引:1  
A previously published paper evaluated election schemes under a wide variety of election circumstances. This paper improves upon the previous work by refining the measures used to rate the election schemes and increasing the statistical significance of those ratings. With these modifications, we can now draw some new conclusions:
  1. In general circumstances, the Borda System outperforms the Copeland System which outperforms Approval which outperforms Majority Rule.
  2. The Maximin Rule — strongly supported by Rawls's — turns out to be a reasonable election rule if the number of election alternatives is large relative to the number of voters.
  3. With two exceptions, all our election systems performed quite well given a society with highly correlated utilities.
  4. Given a polarized society, a serial dictatorship was better than every other election system except Borda.
Perhaps even more importantly, we now have the possibility of conducting some cost/benefit analyses of different proposals for electoral changes.  相似文献

In Morgentaler v. R., the Supreme Court of Canada struck down the abortion provisions in the Criminal Code. In a five to two split, a majority of the Supreme Court judges found that section 251 offended a pregnant woman's constitutionally protected right not to be deprived of her "life, liberty, and security of the person." Sheilah Martin reviews the three majority judgments and focuses on the decision written by Madame Justice Wilson. She believes that Madame Justice Wilson's opinion merits special attention in several regards: her conclusions on the constitutional rights of pregnant women; her recognition and validation of women's perspectives on abortion; and her approach to balancing women's interests in reproductive self-determination against the state's interest in regulating reproduction. Sheilah Martin concludes that this decision will reverberate far into the future. Even though it fails to establish clear guidelines concerning governmental power to control access to abortion, its principles outline the legal framework in which future litigation will occur, and it will limit and shape the terms of any ensuing political debate. In addition, Madame Justice Wilson's judgment holds great promise for those looking to the Court to promote the rights of women and other historically disadvantaged groups.  相似文献
