11. Comparative optics of prosobranch eyes
Sammanfattning : Functional aspects of the large diversity of eye design in prosobranch molluscs was investigated using morphological and optical methods. Three species from different habitats were investigated. Littorina littorea from Scandinavian intertidal rock habitats, Strombus raninus and S. gigas from tropical sand-flats and Ampularia sp.

12. Fish Lenses : Anatomy and Optics
Sammanfattning : I have investigated some of the biological regulatory mechanisms governing the development of crystalline lenses. I used fish as model animals because they possess optically interesting lenses, while the geometrical simplicity of fish lenses allows for studies that are difficult or impossible with the lenses of other animals.

13. The Role of Impaired Interatrial Conduction in Paroxysmal Atrial Fibrillation
Sammanfattning : The aim of this thesis was to evaluate the role of interatrial conduction defects in the genesis of lone paroxysmal atrial fibrillation (AF) using combined approach of non-invasive signal-averaged P-wave ECG, invasive electrophysiological (EP) studies, anatomical studies and animal experiments. Non-filtered signal-averaged P-wave ECG revealed irregularities in orthogonal P-wave morphology and the presence of double-peaked configurations of P-wave spatial magnitude in patients with lone paroxysmal AF compared with healthy individuals (I), suggesting the presence of interatrial conduction delays localised in the posterior-inferior interatrial route.

14. Re-evaluation of exercise-induced muscle soreness : an immunohistochemical and ultrastructural study
Sammanfattning : Delayed onset muscle soreness (DOMS) is a familiar experience for the elite and novice athletes. Symptoms can range from muscle tenderness to severe deliberating pain. It is generally believed that eccentric contractions produce higher tension on muscle fibres and connective tissues than concentric and isometric contractions. LÄS MER
15. Cross transfer effects after unilateral muscle overuse : an experimental animal study about alterations in the morphology and the tachykinin system of muscles
Sammanfattning : Unilateral exercise can produce certain contralateral strength effects. Deleterious events can be cross-transferred as well, as illustrated by a strict symmetry in some chronic inflammatory diseases. LÄS MER
