1. Creating cell microenvironments in vitro
Sammanfattning : Stem cells have a great potential to bring about advancements in fields like developmental biology, drug discovery, cancer biology and tissue engineering. In order to be able to use stem cells to their full potential, it is important to have control over their behavior. LÄS MER
2. Assessment of human swallowing using in-vivo and in-vitro approaches
Sammanfattning : Texture modification is the most vital strategy to manage dysphagia: a condition in which food and beverages are difficult to swallow. Typically thickeners in the form of starch or gums are added to the food to increase the viscosity and thereby reduce the speed of bolus flow. LÄS MER
3. Exploring the role of rheology in bolus flow using an in-vitro approach
Sammanfattning : Swallowing disorders, termed ‘dysphagia’, are more common in the elderly but can also affect younger persons. Approximately, 8% of the world’s population suffers from dysphagia. A Texture Modified Diet (TMD), which increases bolus viscosity to adjust for the sluggish bolus handling mechanism, is the most common intervention. LÄS MER
4. Enzymatic studies of alcohol dehydrogenase by a combination of in vitro and in silico methods
Sammanfattning : The family of alcohol dehydrogenases (ADHs) catalyzes conversions of alcohols, ketons and aldehydes. The early discovery and isolation of ADH (1937) was followed by numerous investigations. It was also the first dimeric enzyme for which the threedimensional structure was determined (1974). LÄS MER
5. Optical Analysis of biological media - continuous wave diffuse spectroscopy
Sammanfattning : The main topic of this thesis is real-time quantification of relevant chromophores and light scattering elements in biological media. The presented methods and instrumentation are based on continuous wave (steady-state) optical measurements of (a) spatially-resolved diffuse reflectance from bulk media and (b) combined spatially-resolved and goniometric measurements of re-emitted light from thin samples.
