In order to investigate the binding properties of the antigen I/IIf from Streptococcus mutans, we analyzed the binding activity of five I/IIf derivatives expressed by I/IIf gene derivatives obtained by insertion of a kanamycin resistance marker. ELISA-derived binding assays showed that the derivatives containing both the N-terminal alanine-rich domain(More)
The induction of tumour necrosis factor (TNF)-alpha from the monocytic cell line THP-1 by the streptococcal antigen I/II from Streptococcus mutans serotype f (protein I/IIf) was studied by use of recombinant polypeptides containing the discrete domains of the protein. The derivatives carrying the N-terminal alanine-rich region (A region) and the adjacent(More)
We tested the hypothesis of a conserved activation mode of monocytic THP-1 cells by proteins I/II expressed by several species of oral streptococci through the specific role of the extended V-region. We studied the binding and modulating activities of six proteins I/II purified from strains representing four different species of oral streptococci, and of(More)
This paper extends previous work on the prediction of passive emitter localization accuracy to the case of multiple closely-spaced sources that emit agile, pulsed waveforms. The proposed approach is based on the iterative calculation of the multi-source Cramér-Rao Bound, conditioned by the probability of generating a measurement for a given source(More)
In this paper, two polarimetric segmentation techniques for polarimetric SAR images are compared. They are both based on the maximum generalised likelihood approach and on a Wishart distribution model. The first technique, named POLSEGANN, is based on a global likelihood approach and on the simulated annealing maximization technique, while the second one(More)
