Host actin cytoskeleton is often targeted by pathogenic bacteria through the secretion of effectors. Legionella pneumophila virulence relies on injection largest known arsenal bacterial proteins, over 300 Dot/Icm type 4 system effectors, into host cytosol. Here, we define functional interactions between VipA and LegK2, two effectors with antagonistic activities towards polymerization that have been proposed to interfere endosomal pathway. We confirmed prominent role LegK2 effector in...

The analysis of electrophysiological signals via a recursive segmentation technique is presented. This method leads to an adaptive time reference linked the fluctuations biorhytms. numerical process yields filtered estimation signal as well its first derivative. simplicity equations involved readily conception microprocessor-based structure. used analyze thoracic impedance waveforms newborn. cyclic nature this made use generate LISSAJOUS patterns which characterize each respiratory cycle....
