  1. 1. Energy Metabolic Stress Syndrome : Impact of Physical Activity of Different Intensity and Duration

    Författare :Stefan Branth; Leif Hambraeus; Gunnar Ronquist; Mats Stridsberg; Lennart Kaijser; Uppsala universitet; []
    Nyckelord :Medicine; energy; ATP; metabolism; nutrition; body-composition; physical-activity; stress; insulin-resistance; ion-pumps; intracellular swelling and -shrinkage; taurine; reactive oxygen species; Medicin;

    Sammanfattning : All living cell functions require an ongoing supply of energy derived from carbohydrates, lipids and proteins with their own pathways of breakdown. All of them end up in the oxidation of reduced coenzymes, yielding chemically-bound energy in the form of adenosine triphosphate (ATP). LÄS MER

    Sammanfattning : Ion transport across membranes is of uttermost importance for us. It is the foundation for signaling of various kinds e.g. in the nerve-system. LÄS MER

  3. 3. Overcoming Limitations of Iontronic Delivery Devices

    Författare :Maria Seitanidou; Magnus Berggren; Daniel T Simon; Christopher Bettinger; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Organic electronic devices are considered as one of the best candidates to replace conventional inorganic electronic devices due to their electronic conductive functionality, low-cost production techniques, the ability to tune their optical and electronic properties using organic chemistry, and their mechanical flexibility. Moreover, these systems are ideal for bioelectronic applications due to their softness, biocompatibility, and most importantly, their electronic and ionic transport. LÄS MER

  4. 4. Time Resolved Diffraction Studies of Structural Changes in Sensory Rhodopsin

    Författare :Robert Bosman; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Rhodopsin; SRII; SRII-HtrII; Time-resolved crystallography; Time-resolved wide angle x-ray scattering; TR-X; TR-WAXS; Serial crystallography;

    Sammanfattning : Responding to different light conditions is an essential process for many organisms on earth. Unicellular organisms are no exception to this and mechanisms for controlling cellular movement must often be sensitive to light. LÄS MER

  5. 5. Metabolic aspects of cardiac arrhythmias

    Författare :Sigfus Gizurarson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiologi; Electrofysiologi; Djurexperiment; Metabolism;

    Sammanfattning : Cardiac arrhythmias are an important cause of mortality and morbidity in patients with cardiac diseases. Sudden death due to ventricular tachycardia and fibrillation (VT/VF) in the setting of acute myocardial infarction (AMI) and heart failure (HF) is a frequent cause of premature death. LÄS MER
