1. 6. GABA-, glycine- and glutamate-induced currents in rat medial preoptic neurons : functional interactions and modulation by capsaicin

   Författare :Urban Karlsson; Staffan Johansson; Johannes Krupp; Bryndis Birnir; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medial preoptic nucleus; synaptic transmission; glutamate; GABA; glycine; TRPV1; Physiology; Fysiologi;

   Sammanfattning : The medial preoptic nucleus (MPN) of the hypothalamus plays a major role in many functions involved in maintaining bodily homeostasis, such as thermoregulation and osmoregulation, as well as in the control of complex behaviours, e.g. sexual behaviour. LÄS MER

3. 7. Heparin coating and cardiotomy suction in cardiopulmonary bypass

   Författare :Staffan Svenmarker; Torkel Åberg; Gunnar Engström; Thomas Karlsson; Jarle Vaage; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; cardiopulmonary bypass; oxygenators; heparin; S100 proteins; blood loss; haemostasis; memory; outcome and process assessment; Kirurgi; Surgery; Kirurgi; kirurgi; Surgery;

   Sammanfattning : The present thesis addresses various means of reducing inflammatory responses associated with cardiopulmonary bypass (CPB) and retransfusion of pericardial suction blood (PSB) during cardiac surgery. Four (I-IV) prospective randomised controlled clinical trials comprising 475 patients were performed in the following areas: effects of heparin coating on measures of clinical outcome and memory function (I, II), inflammatory reactions in PSB and its systemic effects after retransfusion using cardiotomy suction or cell salvage (III) and effects of retransfusion of PSB on memory function and release patterns of protein S100B (IV).

4. 8. Population Differentiation in Solidago virgaurea along Altitudinal Gradients

   Författare :Anna Bergsten; Jon Ågren; Staffan Karlsson; Kari Lehtilä; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; population differentiation; altitudinal gradient; plant nutrient status; resorption efficiency; resorption proficiency; flowering phenology; countergradient variation; reproductive effort; flower production; cost of reproduction; Biology; Biologi; Other biology; Övrig biologi; Ecological Botany; Ekologisk botanik;

   Sammanfattning : Altitudinal gradients offer attractive opportunities for studies of population differentiation in response to environmental heterogeneity. In this thesis, I examined population differentiation along altitudinal gradients by combining common-garden experiments with field studies and experiments in alpine, subalpine and boreal populations of the perennial herb Solidago virgaurea.

5. 9. Structural Growth in Mountain Birch, Betula pubescens ssp. czerepanovii

   Författare :Christina Borg; Brita Svensson; Staffan Karlsson; Seppo Neuvonen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Sammanfattning : In this thesis, I have studied long shoot performance in the monoecious, deciduous tree Betula pubescens ssp. czerepanovii. LÄS MER

7. 10. Using Mobile Health Technology to Support Health-related Quality of Life : From the Perspective of Older Adults with Cognitive Impairment

   Författare :Line Christiansen; Lisa Skär; Johan Sanmartin Berglund; Peter Anderberg; Staffan Karlsson; Blekinge Tekniska Högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aging; Cognitive Impairment; Cohort Studies; Dementia; Gerontechnology; Health-related Quality of Life; Independent Living; Mental Health; Mobile Health; Phenomenography; Quality of Life; Telemedicine; Tillämpad hälsoteknik; Applied Health Technology;

   Sammanfattning : The prevalence of cognitive impairment and illness increases with age. For older adults, maintaining or improving health-related quality of life (HRQoL) in the early stages of cognitive impairment is important to prevent consequences related to the progression of the condition.
