Interaction of lipopolysaccharides and lipid A with complement in rats and its relation to endotoxicity.
Uniform salt forms of endotoxic lipopolysaccharides (LPS) and free lipid A showing distinct differences in their anticomplementary activity, as well as a nontoxic LPS, are used in a new approach of studying the role of complement in endotoxin shock. The use of these defined LPS forms led to the identification of two timely, distinct depressions in complement hemolytic activity after administrat...

15 صفحه اولa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولInteraction between complement subcomponent C1q and bacterial lipopolysaccharides.
The heptose-less mutant of Escherichia coli, D31m4, bound complement subcomponent C1q and its collagen-like fragments (C1qCLF) with Ka values of 1.4 x 10(8) and 2.0 x 10(8) M-1 respectively. This binding was suppressed by chemical modification of C1q and C1qCLF using diethyl pyrocarbonate (DEPC). To investigate the role of lipopolysaccharides (LPS) in this binding, biosynthetically labelled [14...
متن کاملLIPID A and BACTERIAL LIPOPOLYSACCHARIDES
1. Structure and Occurrence The envelope of Gram-negative bacteria, including those of human pathogens such as Escherichia coli and Salmonella enterica, is composed of two distinct lipid membranes: an inner membrane, consisting of glycerophospholipids, and a highly distinctive outer membrane. The latter is an asymmetric bilayer, the outer leaflet of which in most species consists predominantly ...
