Subjectivity is no barrier Citation
Palmer’s “subjectivity barrier” seems to be erected on a popular but highly suspect conception of visual experience, and his “color room” argument is invalid. Palmer beautifully articulates a view that many philosophers and psychologists have found compelling: In attempting to understand the mind, scientists face an impenetrable “subjectivity barrier,” behind which lies the “nature of [our] exp...
متن کاملWzy-dependent bacterial capsules as potential drug targets.
The bacterial capsule is a recognized virulence factor in pathogenic bacteria. It likely works as an antiphagocytic barrier by minimizing complement deposition on the bacterial surface. With the continual rise of bacterial pathogens resistant to multiple antibiotics, there is an increasing need for novel drugs. In the Wzy-dependent pathway, the biosynthesis of capsular polysaccharide (CPS) is r...
متن کاملBacterial capsules and interactions with complement and phagocytes.
actively expressed in circulating neutrophils are those which are either subject to rapid turnover (i.e. those of the contractile machinery and membrane receptors) or those whose rate of biosynthesis needs to be increased during inflammation. It does not appear that mature cells actively synthesize, or upregulate during ‘priming’, those components normally present in high concentrations and/or ...
متن کاملThe demonstration of bacterial capsules by Fontana's staining procedure.
It has been discovered that, in addition to bacterial cells being stained a very dark brown or black color by Fontana's procedure, bacterial capsules are differentially stained a light brown color. Fontana (Dermatol. Wochschr., 55, 1003, 1912 and Pathologica, Genova, 4, 582, 1912) described a method for staining Treponema pallidum and other spirochetes by the AgNO3NH40H method. A similar proced...
متن کاملThe staining of bacterial capsules and slime with ferric compounds.
In 1946 Hale described a method for demonstrating acid mucopolysaccharides in sections based on the affinity of these compounds for colloidal iron oxide in acid solution. The combined iron was demonstrated by conversion to prussian blue. It has been found that bacterial capsules and slime are very well stained by Hale's method. This is possibly due to their content of acid mucopolysaccharides, ...
