Differences in neointimal thickness between the adluminal and the abluminal sides of malapposed and side-branch struts in a polylactide bioresorbable scaffold: evidence in vivo about the abluminal healing process

The goal of this study was to describe the neointimal healing on the abluminal side (ABL) of malapposed (ISA) struts and nonapposed side-branch (NASB) struts in terms of coverage by optical coherence tomography (OCT) and in comparison with the adluminal side (ADL).

Pharmacodynamics of antibiotics in experimental bacterial meningitis--two sides to rapid bacterial killing in the cerebrospinal fluid

In bacterial meningitis, several pharmacodynamic factors determine therapeutic success--when defined as sterilization of the cerebrospinal fluid (CSF); (i) local host defense deficits require the use of bactericidal antibiotics; (ii) CSF antibiotic concentrations that are at least 10-fold above the MBC are necessary for maximal bactericidal activity; (iii) high CSF peak concentrations that lead to rapid bacterial killing appear more important than prolonged suprainhibitory concentrations, probably because very low residual levels in the CSF prevent bacterial regrowth even during relatively long dosing intervals; (iv) penetration of antibiotics into the CSF is significantly impaired by the blood-brain barrier, thus requiring high serum levels to achieve the CSF concentrations necessary for rapid bacterial killing. Beyond these principles, recent data suggest that rapid lytic killing of bacteria in the CSF may have harmful effects on the brain because of the release of biologically active bacterial products. The conflict between the need for rapid CSF sterilization and the harmful consequences of bacterial lysis must be addressed in the therapy of meningitis.

Social Inequality in Political Participation: The Dark Sides of Individualisation

Has the participatory gap between social groups widened over the past decades? And if so, how can it be explained? Based on a re-analysis of 94 electoral surveys in eight Western European countries between 1956 and 2009, this article shows that the difference in national election turnout between the half of the population with the lowest level of education and the half with the highest has increased. It shows that individualisation – the decline of social integration and social control – is a major cause of this trend. In their electoral choices, citizens with fewer resources – in terms of education – rely more heavily on cues and social control of the social groups to which they belong. Once the ties to these groups loosen, these cues and mobilising norms are no longer as strong as they once were, resulting in an increasing abstention of the lower classes on Election Day. In contrast, citizens with abundant resources rely much less on cues and social control, and the process of individualisation impacts on their participatory behaviour to a much lesser extent. The article demonstrates this effect based on a re-analysis of five cumulative waves of the European Social Survey.
