  1. 1. Biologically active terpenoids from Bolivian medicinal plants

    Author : Maribel Lozano Palacios; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bolivian plants; cytotoxicity; triterpenes; damsin; breast cancer;

    Abstract : Pseudo-guaianolides represent a large group of sesquiterpene lactones exhibiting significant cytotoxic and anti-inflammatory activities. Their biological activities are due to a 훼-methylene-훾-lactone unit in their chemical structure, which reacts with free sulfhydryl groups of free cysteine via a Michael-addition. READ MORE

  2. 2. Metabolites of Avena sativa with Blood Cholesterol Lowering Properties

    Author : Narda Thuresson; Centrum för analys och syntes; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cholesterol lowering effect; Avena sativa; phytosterols; avenanthramides; 13-HODE;

    Abstract : Cardiovascular diseases are among the most important causes of death in thedeveloped countries. These diseases are partly caused by too high cholesterolconcentrations in the blood. Avena sativa, oat, is the most common spieces of the genus Avena, and produced in huge amounts worldwide. READ MORE

  3. 3. Microphase Separated Cation Conducting Polymers : Design, Synthesis, and Properties

    Author : Hannes Nederstedt; Centrum för analys och syntes; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Polymer; Litiumbatteri; Mikrofasseparering; Bränslceller; Elektrolyt; Polymerelektrolyt; Polymera bränslecellsmembran; Polymer electrolyte fuel cells; Polymer electrolyte; Polymer electrolyte membrane; Microphase separation; Lithium battery; Polymer; Fuel cell; Proton exchange membrane PEM ;

    Abstract : This thesis describes the synthesis and properties of five different cation conducting polymer systems. These systems were designed so that the polymers would be able to microphase separate into distinct phases with one phase for mechanical strength and one for ionic conductivity. READ MORE

  4. 4. Design, Synthesis and Thermodynamic Studies of Galectin Ligands

    Author : Maria Luisa Verteramo; Centrum för analys och syntes; []
