16. Nanoparticles for multifunctional drug delivery systems
Abstract : Multifunctional drug delivery systems incorporated with stimuli-sensitive drug release, magnetic nanoparticles and magnetic resonance (MR) T2 contrast agents is attracting increasing attention recently. In this thesis, works on polymer nanospheres response to temperature change, superparamagnetic iron oxide nanoparticles (SPION)/polymeric composite materials for MR imaging contrast agents are summarized.

17. Pulsatile insulin release from single islets of Langerhans
Abstract : Insulin release from single islets of Langerhans is pulsatile. The secretory activities of the islets in the pancreas are coordinated resulting in plasma insulin oscillations. Nutrients amplitude-regulate the insulin pulses without influencing their frequency. READ MORE

18. Novel aspects of Na+,K+-ATPase
Abstract : Na,K-ATPase, an integral membrane protein expressed in each eukaryotic cell, serves as the major determinant of intracellular ion composition. In the current study we investigated novel aspects of Na,K-ATPase function and regulation. It is well established that Na,K-ATPase activity is regulated by reversible phosphorylation. READ MORE

19. Mechanisms of insulin exocytosis and release
Abstract : Endocrine cells as well as neurons release their hormones and transmitters by regulated exocytosis. In the pancreatic B-cell, stimuli like glucose initiate biochemical and electrical processes that culminate in influx of Ca2+, which then triggers exocytosis of insulin-containing granules. READ MORE

20. Transformation and Release of Potassium, Chlorine, and Sulfur from Biomass under Conditions Relevant to Dual Fluidized Bed Gasification
Abstract : The transformation and release of ash-forming elements during thermal conversion of biomass areconducive to ash-related problems, for example, agglomeration of bed material in fluidized beds. Theoccurrence and severity of these problems largely depend on the extent to which K, Cl, and S arereleased from biomass during thermal conversion processes. READ MORE
