Serotyping of clinical isolates is a widely used technique for epidemiologic study of group B streptococcal infections. However, serotyping cannot definitively determine epidemiologically related or unrelated isolates. We investigated the use of restriction endonuclease analysis (REA) with both conventional agarose gel electrophoresis (AGE) and pulsed-field gel electrophoresis (PFGE) in 50 isol...

protonophoric agents10). The structural diversity of most of the published pamamycins has been ascribed to the substitution of protons or methyl groups at both parts of the macrodiolide ring by ethyl groups (see c. f. R1, R2, R3, R4 and R5 in Fig. 1)1,2,11). However, variations of the length of the nitrogen-containing side chain at the left side of the pamamycin skeleton (see c. f. R6 in Fig 1)...

In order to explain the occurrence of a minimum in firing rate which occurs for certain mean input levels μ as noise level σ increases (inverse stochastic resonance, ISR) in Hodgkin-Huxley (HH) systems, we analyse the underlying transitions from a stable equilibrium point to limit cycle and vice-versa. For a value of μ at which ISR is pronounced, properties of the corresponding stable equilibri...

One primary function of spatial attention is to exclude external noise [e.g., Psychol. Sci. 11(2) (2000) 139], especially in the region of the target stimulus [J. Vis. 2(4) (2000) 312]. What is not known is the spatial profile of external noise exclusion in the vicinity of the target and how this depends upon attention. The spatial region around an oriented Gabor target was segmented into four ...

Background—Endothelial dysfunction promotes atherosclerosis and precedes acute cardiovascular events. We investigated whether in vivo magnetic resonance imaging with the use of an albumin-binding contrast agent, gadofosveset, could detect endothelial damage associated with atherosclerosis in apolipoprotein E–deficient (ApoE / ) mice. Furthermore, we tested whether magnetic resonance imaging cou...
