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

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

    Abstract : 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").

  2. 2. Brain Tissue Oxygenation in Traumatic Brain Injury : Experimental and Clinical Studies

    Author : Karlis Purins; Anders Lewén; Per Enblad; Oliver Sakowitz; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain tissue oxygenation; Cerebral metabolism; Traumatic brain injury; Cerebral ischemia; Threshold levels; Neurovent-PTO; Microdialysis; Neurosurgery; Neurokirurgi;

    Abstract : Traumatic brain injury (TBI) is a major cause of death and disability. TBI is frequently followed by cerebral ischemia which is a great contributor to secondary brain damage. The main causes of cerebral ischemia are pathophysiological changes in cerebral blood flow and metabolism. READ MORE

  3. 3. Role of the Blood-Brain Barrier in Stereoselective Distribution and Delay in H1 Receptor Occupancy of Cetirizine in the Guinea Pig Brain

    Author : Anubha Gupta; Margareta Hammarlund-Udenaes; Niclas E. Jonsson; Joseph W. Polli; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacokinetics Pharmacotherapy; Cetirizine enantiomers; Brain distribution; Microdialysis; H1 receptor occupancy; Stereoselective-pharmacokinetics; Farmakokinetik Farmakoterapi; PHARMACY; FARMACI;

    Abstract : Cetirizine, an H1-antihistamine, is prescribed for allergic disorders. It exists as a racemic mixture, with levocetirizine being the active enantiomer. The central nervous system side-effects of H1-antihistamines are caused by their penetration into the brain. READ MORE

  4. 4. Neuropeptide Y Receptors in Human, Guinea pig and Chicken : Cloning, in vitro Pharmacology and in situ Hybridization

    Author : Sara Holmberg; Helen Cox; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; G-protein coupled receptor; neuropeptide Y; neuropeptide Y receptor; ortholog; chicken; guinea pig; mutagenesis; receptor computer modeling; mRNA in situ hybridization; Neurovetenskap; Neurology; Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Abstract : Neuropeptide Y (NPY) is known to influence a vast number of physiological and behavioral processes such as vasoconstriction, circadian rhythms, feeding, anxiety and memory. Peptides of the NPY family bind to five different cloned G-protein coupled receptor subtypes (Y1, 2, 4-6). READ MORE

  5. 5. Discordant Neural Xenografting: Analysis and Modulation of Immune Responses

    Author : Lena Cecilia Larsson; Neurobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; Neurologi; neurofysiologi; neurophysiology; neuropsychology; Neurology; immunosuppression; immunology; xenograft; pig; Parkinson s disease; intracerebral transplantation;

    Abstract : Transplantation of embryonic human neural tissue can restore function in patients with Parkinson’s disease, but there is a severe shortage of donor tissue which limits the applicability of the technique. Embryonic neural tissue from other species, xenogeneic tissue, would provide a readily accessible donor tissue with the potential to help patients if the immunological reactions in the host could be prevented.
