Sammanfattning : To understand fluid rheology, properties such as consistency and viscosity are determined in both shear and extensional flow. Many commonly-used materials and formulations exhibit complex rheological properties and in order to determine the behaviour as well as predict and govern their properties, effective and reliable characterisation of these fluids is important.

Sammanfattning : Background and Aims: Muscle contraction involves cross-bridge interaction between actin and myosin filaments, which is regulated by variations of intracellular [Ca2+] and influenced by several external control systems. To characterize the mechanism of contraction, we have studied the effects of pharmacological compounds influencing the actin-myosin interaction and/or Ca2+ activation systems. LÄS MER
4. Conctraction-mediating receptors in human peripheral vessels with special reference to veins and lymphatics
Sammanfattning : By means of a myograph, postjunctional alpha-adrenoceptors were characterized in human superficial epigastric arteries and veins obtained from health subjects. The rank order of potency of subtype selective agonists could not be used for receptor characterization in these vessels, whereas antagonists gave distinct results. LÄS MER
5. Biomechanical consequences of gait impairment at the ankle and foot : Injury, malalignment, and co-contraction
Sammanfattning : The human foot contributes significantly to the function of the whole lower extremity during standing and locomotion. Nevertheless, the foot and ankle often suffer injuries and are affected by many musculoskeletal and neurological pathologies. LÄS MER
