The ‘out-of-type’, violent nature of most regime transformations accounts for the purges in and the extensive replacements of the political personnel, namely of the uppermost officeholders. In the case of Cabinet members, such discontinuities did not imply, however, radical changes in their social profile. Although there were some significant variations, a series of salient characteristics have persisted over time. The typical Portuguese minister is a male in his midforties, of middle-class origin and predominantly urban-born, highly educated and with a state servant background. The two main occupational contingents have been university professors - except for the First Republic (1910-26) - and the military, the latter having only recently been eclipsed with the consolidation of contemporary democracy. As regards career pathways, the most striking feature is the secular trend for the declining role of parliamentary experience, which the democratic regime did not clearly reverse. In this period, a technocratic background rather than political experience has been indeed the privileged credential for a significant proportion of minister

Investigation of high-molecular-weight carboxylic acids in petroleum by different combinations of chromatography (gas and liquid) and mass spectrometry (electron impact and chemical ionization)

International audienceHigh-molecular-weight carboxylic acids from various crude oils were analysed using a combination of chromatographic techniques: liquid chromatography on a modifed absorbent, thin-layer chromatography, glass capillary gas chromatography and combined gas chromatography—mass spectrometry. The polycyclic acids of the hopane series were investigated becase of their importance as biological markers in correlation problems

Identification of surface proteins involved in the adhesion of a probiotic Bacillus cereus strain to mucin and fibronectin

International audienceSeveral Bacillus strains isolated from commercial probiotic preparations were identified at the species level, and their adhesion capabilities to three different model intestinal surfaces (mucin, Matrigel and Caco-2 cells) were assessed. In general, adhesion of spores was higher than that of vegetative cells to the three matrices, and overall strain Bacillus cereusCH displayed the best adhesion. Different biochemical treatments revealed that surface proteins of B. cereusCH were involved in the adhesion properties of the strain. Surface-associated proteins from vegetative cells and spores of B. cereusCH were extracted and identified, and some proteins such as S-layer components, flagellin and cell-bound proteases were found to bind to mucin or fibronectin. These facts suggest that those proteins might play important roles in the interaction of this probiotic Bacillus strain within the human gastrointestinal tract
