The Serotonin Transporter and the Vesicular Monoamine Transporters During Development

Popular Abstract in Swedish POPULÄRVETENSKAPLIG SAMMANFATTNING (Popularized summary in Swedish) Monoaminer Monoaminer såsom serotonin, dopamin, noradrenalin, adrenalin och histamin är alla signalsubstanser syntetiserade från enkla aminosyror. Nervceller som innehåller monoaminer är anatomiskt lokaliserade till hjärnstammen och förlängda märgen. Härifrån försörjer de resten av storhjärnan samt ryIn the present study, the mRNA encoding the serotonin transporter (5-HTT) and two isoforms of the vesicular monoamine transporters (VMAT1 and VMAT2) have been mapped in the rat throughout gestation and early postnatal development using in situ hybridization, RT PCR and immunohistochemistry. 5-HTT mRNA was found in serotonergic neurons and VMAT2 mRNA in all monoaminergic neurons from early gestatio

A tablet computer application for conceptual design

In the conceptual design phase, solutions are reached through an iterative, high-paced and often chaotic manner. Conventional advanced structural analysis software is often too advanced and insufficiently agile to follow this high-paced work pattern. Premature use of advanced structural analysis tools can negatively affect conceptual understanding and the quality of the conceptual design. The mult

Test-grounds of Modernity: A Swedish Landscape in Transformation during the early 20th century

The aim of this paper is to demonstrate some examples of how landscape changes in a rural setting in Sweden during the 19th and early 20th century could be understood as processes of modernity, and how the landscape could be understood as a medium for these changes. One purpose is to to come to a closer understanding of landscape changes during a period that is not so much studied within Swedish h

Nonlinear dimensionality reduction of gene expression data

Using microarray measurements techniques, it is possible to measure the activity of genes simultaneously across the whole genome. Since genes influence each others activity levels through complex regulatory networks, such gene expression measurements are state samples of a dynamical system. Gene expression data has proven useful for diagnosis and definition of disease subgroups, for inference of t

Archimedean spiral antenna for underground soil measurements in Greenland

In this paper, we present a thin single-arm Archimedean spiral antenna designed to be used in underground soil measurements to characterize the dielectric properties of soil during freezing and thawing processes. The designed antenna works in low permittivity, low-loss frozen soil as well as in high permittivity, high-loss marshy soil and operates over the frequency range 1–3 GHz. The antennas has

Iterative equalizer using soft-decoder feedback for MIMO systems in frequency-selective fading

Signals transmitted through Multiple-Input-Multiple-Output (MIMO) systems suffer from multiple access interference (MAI), multipath propagation and additive noise. For such systems, iterative multi-user receivers offer a good tradeoff between performance and complexity. In this paper, the complete structure of such an iterative receiver is presented. It comprises channel estimator, multi-user dete

Paradigm Petrification in the Information Age. An Anatomisation of Knowledge Creation and Deliberation in Innovation Systems in the Human Services

In human service organisations, evidence-based practice (EBP) implies that practice and decision-making should be guided by empirical evidence in a systematic way. Policy makers and researchers argue that practitioners in many fields do not apply state-of-the-art methods and that they should rely on evidence in a more systematic way. Among the suggested reasons for this state of affairs we note la
