The geo-constitution: Understanding the intersection of geography and political institutions

This is the author accepted manuscript. The final version is available from SAGE Publications via the DOI in this record.This paper draws on existing work in the discipline of human geography and cognate fields in order to develop the concept of the ‘geo-constitution’. This concept aims to: (1) highlight the importance of intersections between geography and political institutions in the constitution of government; (2) consider the path-dependent development of political institutions and their impact on statecraft and citizenship; (3) explore the implications of this for political reform. The paper provides an overview of current thinking in political geography and applies the concept of the geo-constitution to the example of devolution and localism in the United Kingdom

Formation of Nano-Bio-Complex as Nanomaterials Dispersed in a Biological Solution for Understanding Nanobiological Interactions

Information on how cells interface with nanomaterials in biological environments has important implications for the practice of nanomedicine and safety consideration of nanomaterials. However, our current understanding of nanobiological interactions is still very limited. Here, we report the direct observation of nanomaterial bio-complex formation (other than protein corona) from nanomaterials dispersed in biologically relevant solutions. We observed highly selective binding of the components of cell culture medium and phosphate buffered saline to ZnO and CuO nanoparticles, independent of protein molecules. Our discoveries may provide new insights into the understanding of how cells interact with nanomaterials

The Conundrum of Order: The Concept of Governance from an Interdisciplinary Perspective

The term governance has made an impressive career in a number of disciplines concerned with regulation, order and law. This chapter draws on insights from legal studies, sociology, political science, anthropology, history and geography to paint a multifaceted picture of existing, competing and complementing approaches to the concept of governance. For reasons of space, the chapter can but point to the different variations on a theme, as governance occupies an ambivalent place in past and present discourses on political (or, legal or economic) order and society. It is argued that beyond pointing to crucial phases of methodological and theoretical transformation within different disciplines such as the often perceived transition ‘from government to governance’, governance is itself a deeply interdisciplinary concept

Activation of Cell Cycle Arrest and Apoptosis by the Proto-Oncogene Pim-2

Potent survival effects have been ascribed to the serine/threonine kinase proto-oncogene PIM-2. Elevated levels of PIM-2 are associated with various malignancies. In human cells, a single Pim-2 transcript gives rise mainly to two protein isoforms (34, 41 kDa) that share an identical catalytic site but differ at their N-terminus, due to in-frame alternative translation initiation sites. In this study we observed that the 34 kDa PIM-2 isoform has differential nuclear and cytoplasmic forms in all tested cell lines, suggesting a possible role for the balance between these forms for PIM-2's function. To further study the cellular role of the 34 kDa isoform of PIM-2, an N-terminally HA-tagged form of this isoform was transiently expressed in HeLa cells. Surprisingly, this resulted in increased level of G1 arrested cells, as well as of apoptotic cells. These effects could not be obtained by a Flag-tagged form of the 41 kDa isoform. The G1 arrest and apoptotic effects were associated with an increase in T14/Y15 phosphorylation of CDK2 and proteasom-dependent down-regulation of CDC25A, as well as with up-regulation of p57, E2F-1, and p73. No such effects were obtained upon over-expression of a kinase-dead form of the HA-tagged 34 kDa PIM-2. By either using a dominant negative form of p73, or by over-expressing the 34 kDa PIM-2 in p73-silenced cells, we demonstrated that these effects were p73-dependent. These results demonstrate that while PIM-2 can function as a potent survival factor, it can, under certain circumstances, exhibit pro-apoptotic effects as well
