A brief period of sublethal cerebral ischemia, followed by several days of recovery, renders the brain resistant to a subsequent lethal ischemic insult, a phenomenon termed ischemic preconditioning or tolerance. Ischemic tolerance was established in the rat two-vessel occlusion model of ischemia, induced by occlusion of both carotid arteries in combination with hypotension. Ischemic preconditionin

A short period of sublethal preconditioning ischemia (3 min) followed by two days of reperfusion provides almost complete protection against ischemic cell death induced by a second (9 min) lethal ischemic episode. Here, we have investigated the extracellular signal-regulated protein kinase kinase and extracellular signal-regulated protein kinase, two kinases known to activate gene transcription an

Popular Abstract in Swedish Allt levande består till stor del av proteiner. De bygger upp muskler och hår, transporterar syre i blodet och ser till att kemin i kroppen fungerar som den ska. Men hur tillverkas då dessa proteiner? Jo i alla celler finns ribosomer, proteinfabriker. En bakterieribosom är ungefär 0.02 mikrometer stor. Den är sammansatt av proteiner och RNA-kedjor. RNA utgör den funktioTranslation is a central biological process, that is catalysed by a machinery consisting of RNA and protein. In this thesis three different protein components of the bacterial protein synthesis system have been structurally studied. Ribosome recycling factor (RRF) is essential for the recycling step of the translation cycle, elongation factor SelB is a specialised elongation factor needed for co-t

An introduction to the beginning of a health professional Bachelor project

In this grounded theory study, the authors analyze interviews and participant observation data related to palliative cancer nursing in hospitals. Striving for Emotional Survival emerged as the pattern of behavior through which nurses deal with their main concern, the risk of being emotionally overloaded by their work. It involved three main strategies: Emotional Shielding through Professional Shie

The environmental footprint of IT products are significant and, in spite of manufacturing and product design improvements, growing consumption of electronics results in increasing absolute environmental impact. Computers have short technological lifespan and a lot of the in-build performance, although necessary, remains idling for most of the time. Today, most of computers used in non-residential

In our response, we address four themes arising from the commentaries. First, we discuss the distinction between cognition and metacognition and show how to draw it within our framework. Next, we explain how metacognition differs from social cognition. The underlying mechanisms of metacognitive development are then elucidated in terms of interaction patterns. Finally, we consider measures of metac

In the present work we have selected a collection of statistical and mathematical tools useful for the exploration of multivariate data and we present them in a form that is meant to be particularly accessible to a classically trained mathematician. We give self contained and streamlined introductions to principal component analysis, multidimensional scaling and statistical hypothesis testing. Wit

This study compares students' experiences of two types of criteria-based assessment: in text commentary and rubric-articulated feedback, in an assessment design combining the two feedback channels. The main aim is to use students' responses to shed light on how feedback strategies for formative assessment can be optimised. Following action research methodology, the study discusses key categories o
