1. Skeletal muscle calcium homeostasis during fatigue : modulation by kinases and mitochondria
Sammanfattning : The use of skeletal muscles in daily activities and even during strenuous exercise resulting in fatigue requires precise regulation of force and the timing of contraction. To achieve such performance characteristics, vertebrate skeletal muscles have developed a unique control mechanism for regulating the free Ca2+ concentration in their myoplasm ([Ca2+]i). LÄS MER
2. Cellular electrophysiological modulation in chronic atrial fibrillation - Studies with magnesium and GIK solution
Sammanfattning : Although chronic atrial fibrillation (CAF) is the most common sustained cardiac arrhythmia in man, the mechanisms involved in its progressive course are still not fully understood. Recent studies have verified an electrical remodelling of the atrial myocardium that may be responsible for the electrophysiological disturbances known to exist in the fibrillating atria. LÄS MER
3. The choreography of protein vibrations : Improved methods of observing and simulating the infrared absorption of proteins
Sammanfattning : The work presented in this thesis has striven toward improving the capability to study proteins using infrared (IR) spectroscopy. This includes development of new and improved experimental and theoretical methods to selectively observe and simulate protein vibrations. LÄS MER
4. Infrared spectroscopy : a tool for protein characterization
Sammanfattning : Infrared (IR) spectroscopy, which belongs to vibrational spectroscopy, detects the vibrations of molecules, for example, proteins. The absorption of the peptide group gives rise to 9 characteristic bands in the infrared region, named A, B, I-VII, with a decreasing energy or wavenumber (cm-1). LÄS MER
5. Developmental regulation of smooth muscle contraction in the urinary bladder
Sammanfattning : Smooth muscle cells in the urinary bladder are involved in the control of urine filling and emptying. We have used mice to study the contractile regulation of urinary bladder smooth muscle during the fetal period. LÄS MER
