Growing up beside you: a relational sociology of early childhood

This article will begin by outlining influential attempts by historians and sociologists to develop a more adequate theoretical understanding of past and contemporary childhoods, focusing on the major problems that stem from the pivotal role that ‘developmentalism’ plays in their arguments. I will argue that sociologists can overcome some of their deepest fears about the role of developmental psychology by developing a relational approach that integrates the biological and social aspects of children’s development. In the development of a relational sociology of early childhood we need to make important connections with closely related disciplines, but at the same time draw on and integrate research findings from relevant areas within the social and natural sciences. An alternative perspective drawn from the writings of Norbert Elias will be put forward and illustrated by discussing some of the key concepts that Elias and Vygotsky used to explain the language development of young children

Circulating microparticles: square the circle

Background: The present review summarizes current knowledge about microparticles (MPs) and provides a systematic overview of last 20 years of research on circulating MPs, with particular focus on their clinical relevance. Results: MPs are a heterogeneous population of cell-derived vesicles, with sizes ranging between 50 and 1000 nm. MPs are capable of transferring peptides, proteins, lipid components, microRNA, mRNA, and DNA from one cell to another without direct cell-to-cell contact. Growing evidence suggests that MPs present in peripheral blood and body fluids contribute to the development and progression of cancer, and are of pathophysiological relevance for autoimmune, inflammatory, infectious, cardiovascular, hematological, and other diseases. MPs have large diagnostic potential as biomarkers; however, due to current technological limitations in purification of MPs and an absence of standardized methods of MP detection, challenges remain in validating the potential of MPs as a non-invasive and early diagnostic platform. Conclusions: Improvements in the effective deciphering of MP molecular signatures will be critical not only for diagnostics, but also for the evaluation of treatment regimens and predicting disease outcomes
