  2. 1. 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

  4. 2. Drug Delivery to the Brain by Liposomes : Understanding Factors Governing Delivery Outcomes In Vivo

    Author : Yang Hu; Margareta Hammarlund-Udenaes; Teresa Dalla Costa; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanocarrier; liposome; blood-brain barrier; brain delivery; formulation; methotrexate; diphenhydramine; microdialysis; pharmacokinetics; model-based approach; Farmaceutisk vetenskap; Pharmaceutical Science; Farmakokinetik och läkemedelsterapi; Pharmacokinetics and Drug Therapy;

    Abstract : The blood-brain barrier (BBB) is the primary obstacle for efficient drug delivery to the central nervous system (CNS). One promising strategy to enhance brain delivery is to utilize nanocarriers (NC), e.g., liposomes, encapsulating CNS drugs. READ MORE

  5. 3. Tryptophan-related Neurotransmission in the Brain: Disturbances Associated with Experimental Hepatic Encephalopathy

    Author : Peter B F Bergqvist; Avdelningen för klinisk kemi och farmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tetrodotoxin; serotonin; release; rat; quinolinic acid; potassium; chloroamphetamine; noradrenaline; neurotransmission; microdialysis; hepatic encephalopathy; fenfluramine; drug safety; dopamine; coma; citalopram; ammonia; calcium; brain; tryptophan; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Abstract : In the present study, L-tryptophan (TRP)-related disturbances in the brain in experimental hepatic encephalopathy (HE) were investigated. The endogenous NMDA-receptor agonist and L-TRP metabolite quinolinic acid (QUIN) has been suggested to be involved in the pathogenesis of HE. READ MORE

  6. 4. Quantitative Aspects of Nanodelivery Across the Blood-Brain Barrier : Exemplified with the Opioid Peptide DAMGO

    Author : Annika Lindqvist; Margareta Hammarlund-Udenaes; Markus Fridén; William Elmquist; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood-brain barrier; liposomes; nanocarriers; brain delivery; pharmacokinetics; modeling and simulation; microdialysis; opioid peptide; DAMGO; LC-MS MS; Farmaceutisk vetenskap; Pharmaceutical Science;

    Abstract : The use of nanocarriers is an intriguing approach in the development of efficacious treatment for brain disorders. The aim of the conducted research was to evaluate and quantify the impact of a liposomal nanocarrier formulation on the brain drug delivery. READ MORE

  7. 5. Microdialysis and Intensive Care. Clinical and experimental studies

    Author : Per Ederoth; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; traumatic brain injury; glucose; glycerol; lipolysis; epidural; postoperative analgesia; experimental pancreatitis; human; blood-brain barrier; morphine; pharmacokinetics; Microdialysis; intensive care; Anestesiologi; intensivvård;

    Abstract : Microdialysis was used to monitor local concentrations of energy metabolites in different organs, and to study the pharmacokinetics of morphine over the blood-brain barrier in intact and injured brain tissue in conditions treated in the Intensive Care Unit. After major abdominal or thoracoabdominal surgery, postoperative thoracic epidural analgesia resulted in higher glycerol concentrations in the deltoid subcutaneous adipose tissue, implying increased lipolysis, on the third postoperative day as compared to intravenous infusion of morphine, possibly due to a locally increased sympathetic tone.
