Tissue damage induces early recruitment of neutrophils through redox-regulated Src family kinase (SFK) signaling in neutrophils. Redox-SFK signaling in epithelium is also necessary for wound resolution and tissue regeneration. How neutrophil-mediated inflammation resolves remains unclear. In this paper, we studied the interactions between macrophages and neutrophils in response to tissue damage in zebrafish and found that macrophages contact neutrophils and induce resolution via neutrophil reverse migration. We found that redox-SFK signaling through p22phox and Yes-related kinase is necessary for macrophage wound attraction and the subsequent reverse migration of neutrophils. Importantly, macrophage-specific reconstitution of p22phox revealed that macrophage redox signaling is necessary for neutrophil reverse migration. Thus, redox-SFK signaling in adjacent tissues is essential for coordinated leukocyte wound attraction and repulsion through pathways that involve contact-mediated guidance.

During translation, consecutive ribosomes load on an mRNA and form a polysome. The first ribosome binds to a single-stranded mRNA region and moves toward the start codon, unwinding potential mRNA structures on the way. In contrast, the following ribosomes can dock at the start codon only when the first ribosome has vacated the initiation site. Here we show that loading of the second ribosome on a natural 38-nt-long 5′ untranslated region oflppmRNA, which codes for the outer membrane lipoprotein fromEscherichia coli, takes place before the leading ribosome has moved away from the start codon. The rapid formation of this standby complex depends on the presence of ribosomal proteins S1/S2 in the leading ribosome. The early recruitment of the second ribosome to the standby site before translation by the leading ribosome and the tight coupling between translation elongation by the first ribosome and the accommodation of the second ribosome can contribute to high translational efficiency of thelppmRNA.

In this chapter, we investigate the recent situation concerning the seduction of consumers by advertising and the media. A new plethora of media-organised conglomerates is attempting to monopolise our attention and steer our emotions, opinions and choices towards increased consumption through imposed wants in the interest of gross profits for a semi-invisiblised few. Herein we consider: the colonisation of public places (advertising), the work/spend cycle, increased work at the cost of leisure; impression management, status-conscious and conspicuous consumption, reflective versus pre-reflective thinking in consumer choices, the early recruitment of children, how human emotions can become the fuel of overconsumption, class-based emotions and fashion consumption, obsessions with body image, the evasion and silencing of criticism by the corporate media. The approach is one founded in critical theory - a perspective that describes the individual as reciprocally constituted by the society in which she lives, rather than as a passive entity existing prior to socialisation. It seeks to reveal the seduction of our subjectivities (running marketing strategies ‘from within') as contrasted with the value-free, ‘objective' approach of much contemporary social psychology. Contemporary theoreticians in sociology and consumer studies, including Pierre Bourdieu and Juliet Schor, are cited along with deeper philosophical perspectives from the earlier philosopher, Jean-Paul Sartre, complete with references from contemporary books and journals.

SummaryDuring their journey from the blood stream to sites of inflammation polymorphonuclear leukocytes (PMN) release a wide panoply of granule proteins. Shortly after the PMN efflux, the extravasation of monocytes sets in and recent research provides evidence that the release of PMN granule proteins and monocyte extravasation are causally interrelated. Granule proteins seeded on the endothelium by adherent PMN allow direct activation and subsequent adhesion of monocytes. In addition, PMN granule components enhance the endothelial expression of cell adhesion molecules, efficiently supporting the arrest of monocytes at inflamed vessels. Moreover, granule proteins contribute to the fine tuning of the local chemokine network. Proteolytic modification of chemokines as well as enhancement of local chemokine synthesis lead to increased monocyte extravasation. Finally, PMN granule proteins exert direct chemotactic effects, a mechanism which is of special importance in the early recruitment of inflammatory monocytes. Hence, granule proteins modify the monocyte extravasation cascade in a multifaceted manner ensuring the efficiency of these mechanisms.

AbstractThe Wisconsin Twin Project encompasses nearly 30 years of longitudinal research that spans infancy to early adulthood. The twin sample was recruited from statewide birth records for birth cohorts 1989–2004. We summarize early recruitment, assessment, retention and recently completed twin neuroimaging studies. In addition to the focal twins, longitudinal data were also collected from two parents and nontwin siblings. Our adolescent and young adult neuroimaging sample (N = 600) completed several previous behavioral and environmental assessments, beginning shortly after birth. The extensive phenotyping is meant to support a range of empirical investigations with potentially differing theoretical perspectives.
