  1. 1. Signal transduction in the brain : modulation of receptor-mediated inositol phospholipid breakdown by potassium and fluoride ions

    Författare :Gunnar Tiger; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inositol phospholipid breakdown; muscarinic receptors; potassium; fluoride; rat brain; pig brain;

    Sammanfattning : Neurotransmitter receptor types mediating the generation of intracellular signals are of two types; ligand-gated ion channels and G protein coupled receptors. The effector enzyme phosphoinositide-specific phospholipase C (PLC) is modulated by stimulation of G protein coupled receptors, leading to an increased breakdown of inositol phospholipids ("Ptdlns breakdown").

  3. 2. 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).

  4. 3. Secondary Insults in Neurointensive Care of Patients with Traumatic Brain Injury

    Författare :Kristin Elf; Per Enblad; Pelle Nilsson; Elisabeth Ronne-Engström; Bertil Romner; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Traumatic brain injury; Neurointensive care; Monitoring; Secondary insults; Intracranial pressure; Cerebral perfusion pressure; Pressure reactivity; Temperature; Neural network; Outcome; Neurovetenskap; Neurology; Neurologi;

    Sammanfattning : Traumatic brain injury (TBI) is a major cause of death and disability. Intracranial secondary insults (e.g. intracranial haematoma, brain oedema) and systemic secondary insults (e. LÄS MER

  5. 4. Intranasal Cooling for Cerebral Hypothermia Treatment

    Författare :Lucian Covaciu; Sten Rubertsson; Jan Weis; Peter Andrews; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Selective brain cooling; cerebral hypothermia; therapeutic hypothermia; cardiac arrest; stroke; traumatic brain injury; brain temperature; magnetic resonance spectroscopy; trigeminal reflex; Intensive care; Intensivvård; Radiology; Radiologi; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : The controlled lowering of core body temperature to 32°C to 34°C is defined as therapeutic hypothermia (TH). Therapeutic hypothermia has been shown to improve neurological outcome and survival in unconscious patients successfully resuscitated after cardiac arrest. LÄS MER

  7. 5. The role of bacterial endotoxin in the immature brain

    Författare :Saskia Eklind; Göteborgs universitet; []
    Nyckelord :lipopolysaccharide; hypoxia-ischemia; immature; temperature; cerebral blood flow; blood glucose; inflammation; apoptosis; microarray; preconditioning;

    Sammanfattning : Aim: Epidemiological evidence suggests that infections may increase the vulnerability of the immature brain to further insults. The aim of this thesis was to investigate the role of bacterial endotoxin (lipopolysaccharide, LPS) on hypoxic-ischemic (HI) injury in the immature rat brain, and to evaluate possible underlying mechanisms of increased sensitivity.
