  1. 1. Experimental cardiopulmonary cerebral resuscitation : with special reference to cerebral eicosanoid production and free radical scavengers

    Författare :Xiaoli Liu; Marianne Forsman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; cerebral resuscitation; reperfusion damage; oxidative injury; eicosanoid; free radical scavenger; neurological function; alkaline buffer; S-PBN; PBN; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anestesiologi; Anaesthesiology;

    Sammanfattning : Reperfusion injury after restoration of spontaneous circulation (ROSC) is often considered one of the predominant factors in determining neurological outcome in cardiac arrest. Therefore one of the main targets of experimental and clinical studies has been to mitigate this reperfusion injury. LÄS MER

  3. 2. Augmentation of vital organ blood flow during experimental cardiopulmonary resuscitation

    Författare :Rolf Gedeborg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cardiac arrest; cardiopulmonary resuscitation; epinephrine; high-dose epinephrine; buffer; cerebral blood flow; post-resuscitation period; aortic occlusion; Kirurgi; Surgery; Kirurgi; Anestesiologi; Anaesthesiology;

    Sammanfattning : Clinical outcome from cardiac arrest remains poor. If the time from arrest to restoration of spontaneous circulation can be shortened and resuscitation techniques improved so that higher blood flow and oxygen delivery to vital organs is achieved, it is possible that the outcome from cardiac arrest could improve.

  4. 3. Enzyme Immunoassay in Combination with Liquid Chromatography for Sensitive and Selective Determination of Drugs in Biosamples

    Författare :Ulf Lövgren; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; amplification; alkaline phosphatase; enzyme immunoassay; liquid chromatography; flow-injection; micellar; Analytisk kemi;

    Sammanfattning : Two different sensitive microtitre-plate based enzyme immunoassays were developed and evaluated for determination of the model drug compound, budesonide, in blood plasma. In the first approach, high sensitivity was obtained by using amperometric detection in a flow injection system for determination of the enzyme product p-aminophenol. LÄS MER

  5. 4. Biochemical conversion of biomass to biofuels : pretreatment–detoxification–hydrolysis–fermentation

    Författare :Venkata Prabhakar Soudham; Jyri-Pekka Mikkola; Christer Larsson; Tom Birger Granström; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulosic materials; Ionic liquids; Pretreatment; Inhibitors; Detoxification; Ferrous sulfate and hydrogen peroxide; reducing agents; alkaline treatments; Hydrolysis; Fermentation; Biofuels; biokemi; Biochemistry;

    Sammanfattning : The use of lignocellulosic materials to replace fossil resources for the industrial production of fuels, chemicals, and materials is increasing. The carbohydrate composition of lignocellulose (i.e. cellulose and hemicellulose) is an abundant source of sugars. LÄS MER

  7. 5. Alkaline Urine Dehydration : how to dry source-separated human urine and recover nutrients?

    Författare :Prithvi Simha; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Human urine is a renewable resource from which water, nutrients and energy can be recovered and safely recycled. This thesis presents a novel on-site technology, called alkaline dehydration, for recovering nutrients from source-separated urine. LÄS MER
