  1. 1. Regulation of NMDA receptor properties by amino acids and cations : a biochemical and electrophysiological study

    Författare :Yun Liu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NMDA receptor; Glutamate; Glycine; [3H]MK-801 binding; Magnesium; Calcium; Tris; Potassium; Sodium; Proton; Xenopus oocytes; Spinal cord; Cerebral cortex; Receptor binding; Electrophysiology;

    Sammanfattning : NMDA receptors are glutamate-regulated ion channels that are permeable to Ca2+, Na+ and K+ and are sensitive to voltage-dependent Mg2+-block. To investigate the modulatory effects of amino acids and cations on NMDA receptors and the possible regional differences in the pharmacology of NMDA receptors, I used mainly two techniques in this thesis: electrophysiological analysis of expressed NMDA receptors in Xenopusoocytes and biochemical receptor binding using [3H]MK-801 in membrane preparations from the rat cerebral cortex and spinal cord.

  3. 2. Smooth muscle hypertrophy and the IGF-system

    Författare :Yun Chen; David R. Clemmons; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Insulin-like growth factor-! (IGF-I) has both metabolic and mitogenic effects on smooth muscle cells (SMCs). The effects of IGF-I are modified by a group of binding proteins (IGFBPs). The present study was devoted to smooth muscle hypertrophy and the IGF-system in smooth muscle under different conditions.

  4. 3. Computational study of Polymerization, Crystallization and Mechanical Properties of Conducting Polymers

    Författare :Donghyun Kim; Igor Zozoulenko; Xavier Crispin; Mathieu Linares; Yun Hee Jang; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nowadays, electronic devices that include conducting polymers, ranging from batteries and OLED panel for TVs and smartphones to bioelectronics devices such as sensors and ion-pumps for drug-delivery are widely used in our life. The use of conducting polymer in many electronic applications was driven by demand for light weight, flexibility or biocompatibility with the performance on pair with conventional inorganic counterparts.
