  1. 11. 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. 12. Protection against cold in prehospital trauma care

    Författare :Otto Henriksson; Ulf Björnstig; Tore Vikström; Peter Naredi; Hannu Rintamäki; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hypothermia; prehospital trauma care; emergency medical services; passive warming; thermal insulation; heat loss; body temperature regulation; kirurgi; Surgery;

    Sammanfattning : Background: Protection against cold is vitally important in prehospital trauma care to reduce heat loss and prevent body core cooling. Objectives: Evaluate the effect on cold stress and thermoregulation in volunteer subjects byutilising additional insulation on a spineboard (I). LÄS MER

  4. 13. Immune-to-Brain Signaling in Fever : The Brain Endothelium as Interface

    Författare :Elahe Mirrasekhian; David Engblom; Anders Blomqvist; Simin Mohseni; Tomas Deierborg; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Fever is a brain-regulated elevation of body temperature that occurs in response to infectious and non-infectious stimuli. During inflammatory episodes, circulating cytokines that are released by activated immune cells, trigger the induction of cyclooxygenase (COX)-2 in the ventromedial preoptic area of the hypothalamus (the thermoregulation center).

  5. 14. Studies of sympathetic nerve activity in cutaneous nerves in healthy subjects using intraneural microneurography : The relationship between nerve activity and effector organ response

    Författare :Pirkko Hynninen; Anna Rostedt Punga; Roland Flink; Kristin Ørstavik; Uppsala universitet; []
    Nyckelord :Human; microneurography; neurophysiology; sympathetic nerve activity;

    Sammanfattning : The aim of the research presented in this thesis is to gain new knowledge of the characteristic features of sympathetic nerve activity of cutaneous nerves in healthy adult humans using intraneural microneurography. One further goal is to study the relationship between nerve activity and effector organ response. LÄS MER

  7. 15. Population ecology at the range edge : survival and dispersal of a high-density lepidopteran population

    Författare :Cecilia Ronnås; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Outbreaks of pest species can cause extensive damage to arable crops and to forest production. Some pests also present severe health hazards to humans and animals. LÄS MER
