Risk-related standards of competence: continuing the debate over risk-related standards of competence 总被引:1,自引:0,他引:1
Cale GS 《Bioethics》1999,13(2):131-148
This discussion paper addresses Ian Wilks' defence of the risk-related standard of competence that appears in Bioethics 11 . Wilks there argues that the puzzle posed by Mark Wicclair in Bioethics 5 against Dan Brock's argument in favour of a risk-related standard of competence — namely that Brock's argument allows for situations of asymmetrical competence — is not a genuine problem for a risk-related standard of competence. To show this, Wilks presents what he believes to be two examples of real situations in which asymmetrical competence arises.
I argue that insofar as Wilks equivocates two senses of competence in his examples — namely, competence to perform a task and competence in performing a task — Wilks is unable to illustrate the existence of real situations of asymmetrical competence. By examining the way in which Wilks equivocates two senses of competence in his examples, and by applying the results of this examination to the problem of patient competency within the medical field, I argue that not only does Wilks fail to show that situations of asymmetrical competence exist, but he is also unable to provide a foundation for understating how the risk-related standard of competence can strike a balance between an individual's autonomy and benevolent intervention.
I thus conclude that insofar as Wilks fails to answer the objections raised by Wicclair and others against the risk-related standard of competence, the risk-related standard of competence continues to be undermined by the problem of asymmetrical competence. 相似文献

Introduction
Development of cell therapies for repairing the intervertebral disc is limited by the lack of a source of healthy human disc cells. Stem cells, particularly mesenchymal stem cells, are seen as a potential source but differentiation strategies are limited by the lack of specific markers that can distinguish disc cells from articular chondrocytes. 相似文献5.

Pregnancy enhanced nitric oxide production by uterine artery endothelial cells (UAEC) is the result of reprogramming of both Ca(2+) and kinase signaling pathways. Using UAEC derived from pregnant ewes (P-UAEC), as well as COS-7 cells transiently expressing ovine endothelial nitric oxide synthase (eNOS), we investigated the role of phosphorylation of five known amino acids following treatment with physiological calcium-mobilizing agent ATP and compared with the effects of PMA (also known as TPA) alone or in combination with ATP. In P-UAEC, ATP stimulated eNOS activity and phosphorylation of eNOS S617, S635, and S1179. PMA promoted eNOS phosphorylation but without activation. PMA and ATP cotreatment attenuated ATP-stimulated activity despite no increase in phospho (p)-T497 and potentiation of p-S1179. In COS-7 cells, PMA inhibition of ATP-stimulated eNOS activity was associated with p-T497 phosphorylation. Although T497D eNOS activity was reduced to 19% of wild-type eNOS with ATP and 44% with A23187, we nonetheless observed more p-S1179 with ATP than with A23187 (3.4-fold and 1.8-fold of control, respectively). Furthermore, the S1179A eNOS mutation partly attenuated ATP- but not A23187-stimulated activity, but when combined with T497D, no further reduction of eNOS activity was observed. In conclusion, although phosphorylation of eNOS is associated with activation in P-UAEC, no single or combination of phosphorylation events predict activity changes. In COS-7 cells, phosphorylation of T497 can attenuate activity but also influences S1179 phosphorylation. We conclude that in both cell types, observed changes in phosphorylation of key residues may influence eNOS activation but are not sufficient alone to describe eNOS activation. 相似文献

Background
The widespread problem of antibiotic resistance in pathogens such as Staphylococcus aureus has prompted the search for new antimicrobial approaches. In this study we report for the first time the use of a light-activated antimicrobial agent, methylene blue, to kill an epidemic methicillin-resistant Staphylococcus aureus (EMRSA-16) strain in two mouse wound models. 相似文献9.
