A toy Australian shepherd dog was referred for bile peritonitis following excision of a biliary mucocele. Subsequent delayed gastric emptying was refractory to prokinetic therapy but responded to injection of botulinum toxin A into the muscularis layer of the pylorus; a novel therapy for delayed gastric emptying in dogs. 相似文献

Type III secreted "effector" proteins of bacterial pathogens play central roles in virulence, yet are notoriously difficult to identify. We used an in vivo genetic screen to identify 13 effectors secreted by the type III apparatus (called Hrp, for "hypersensitive response and pathogenicity") of the plant pathogen Pseudomonas syringae. Although sharing little overall homology, the amino-terminal regions of these effectors had strikingly similar amino acid compositions. This feature facilitated the bioinformatic prediction of 38 P. syringae effectors, including 15 previously unknown proteins. The secretion of two of these putative effectors was shown to be type III--dependent. Effectors showed high interstrain variation, supporting a role for some effectors in adaptation to different hosts. 相似文献

Robotics researchers increasingly agree that ideas from biology and self-organization can strongly benefit the design of autonomous robots. Biological organisms have evolved to perform and survive in a world characterized by rapid changes, high uncertainty, indefinite richness, and limited availability of information. Industrial robots, in contrast, operate in highly controlled environments with no or very little uncertainty. Although many challenges remain, concepts from biologically inspired (bio-inspired) robotics will eventually enable researchers to engineer machines for the real world that possess at least some of the desirable properties of biological organisms, such as adaptivity, robustness, versatility, and agility. 相似文献

This paper is an evaluation of the sociological significance of the development and adoption of sustainable agricultural practices. The concept of “appropriationism” is introduced as a means of determining whether or not sustainable agriculture is an expression of class antagonisms in U. S. agriculture. “Appropriationism” is the process by which corporate agribusiness replaces natural processes with industrial products. A comparison of responses to farm crisis in the late 19th century and in the 1980s is employed as a heuristic device to determine the contemporary sociological significance of sustainable agriculture. Based on past experience and changes in key institutions over the past century, it is concluded that the development of sustainable agricultural practices will not significantly challenge the economic prerogatives of agribusiness and that the long-term process of the industrial appropriation of natural processes in agriculture will continue into the 21st century. 相似文献
