  1. 1. Dynamics of Ca2 handling in vascular smooth muscle

    Författare :Karl Dreja; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; smooth muscle; phenotypic modulation; caveolae; Physiology; confocal microscopy; calcium; Fysiologi;

    Sammanfattning : Intracellular Ca2+ is a key regulator of vascular contractility, and thereby of blood perfusion and pressure. Ca2+ signals are essential also for cell migration, proliferation and regulation of numerous enzymes. LÄS MER

    Sammanfattning : Modern biological research has benefited from a renaissance in light microscopy, brought about by the convergence of developments in fields as diverse as electronics, optics, molecular biology, computer science, and reagent chemistry. Integration of these has transformed microscopy into a highly useful, dynamic research tool for biology and medicine. LÄS MER

  3. 3. Cellobiose dehydrogenase on electrodes - an electrochemical biosensor for various analytes tunable by positive charges

    Författare :Christopher Schulz; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cellobiose dehydrogenase; direct electron transfer; amperometric biosensor; glucose; lactose; cellobiose; calcium; polycation; graphite; gold; electrode;

    Sammanfattning : Cellobiose dehydrogenase (CDH) is a sugar oxidizing enzyme secreted by various species of wood degrading fungi to assist the process of wood degradation. It can oxidise analytically relevant sugars as cellobiose, lactose or glucose leading to a gain of two electrons per sugar molecule. LÄS MER
