Stress-Induced Alterations In Hippocampal Plasticity, Place Cells, And Spatial Memory, Jeansok J. Kim, Hongjoo J. Lee, Adam C. Welday, Eunyoung Song, Jeiwon Cho, Patricia E. Sharp, Min W. Jung, Hugh T. Blair

Patricia E Sharp

Acute, inescapable, and unpredictable stress can profoundly modify brain and cognition in humans and animals. The present study investigated the ensuing effects of 2-h variable "audiogenic" stress on three related levels of hippocampal functions in rats: long-term potentiation, place cell activity, and spatial memory. In agreement with prior findings, we observed that stress reduced the magnitude of Schaffer collateral/commissural-Cornu Ammonis field 1 long-term potentiation in vitro, and selectively impaired spatial memory on a hidden platform version of the Morris water maze task. We also observed that stress impaired the stability of firing rates (but not firing locations) of place cells …

Basics Of Mergers, Acquisitions And Corporate Restructuring: The Nigerian Experience., Ozy B. Orluwene Jp, Hycenth A. Ajie

Dr Ozy B.Orluwene,JP

ABSTRACT: This paper is primarily concerned with examining the role of mergers and acquisitions (M&As) in corporate restructuring as an instrument of enhancing efficiency, size and developmental roles. The last few years have witnessed an astronomical increase in world of corporate restructuring through M&As. The trend has been influenced by factors such as prospects of cost saving due to economies of scale as well as more efficient allocation of resources; enhanced efficiency in resources allocation and risk reduction arising from improved management at points of allocation and utilization of resources. M&As especially in the banking industry are now a global …

Current And Future Status Of Chemistry Collections And Chemistry Libraries At Arl Institutions, Jeremy R. Garritano

Libraries Research Publications

The process of consolidating science and technology branch libraries in academic institutions is not new, but with ease of access to electronic resources, and with shrinking budgets and interdisciplinary research the norm, the idea of consolidation has become more attractive in the past decade. This article reports on the results of a 2005 survey of Association of Research Libraries (ARL) institutions and the status of their chemistry-related library resources and facilities. The past, present, and future of these chemistry collections will be discussed with emphasis on those having consolidated in the last ten years or those who plan to consolidate …
