1. Quantitative Tracer Based MRI Perfusion : Potentials and Limitations
Sammanfattning : Tracer based MRI perfusion measurements is a clinically useful tool to assess regional distributions of tissue blood flow and volume. The method may be based on any of the three relaxation mechanisms T1, T1 and T2*, the latter denoted DSC-MRI being the most common. LÄS MER
2. Tools for the development of intensified perfusion processes for mammalian cell culture
Sammanfattning : Recombinant protein therapeutics have become an indispensable part of modern medicine to treat a wide variety of diseases. Their manufacture is mostly based on mammalian cells with fed-batch production bioreactors and downstream batch purification unit operations. LÄS MER
3. The effect of mechanical ventilation on abdominal organs : Analysing the role of PEEP and perfusion
Sammanfattning : Background: The effect of mechanical ventilation on abdominal organs is not well understood and investigated yet. Previous studies, using an animal sepsis-like model, found an association between mechanical ventilation (MV) and abdominal edema and inflammation. LÄS MER
4. Radiolabeled acetate PET in oncology imaging : studies on head and neck cancer, prostate cancer and normal distribution
Sammanfattning : The use of positron emission tomography (PET) for imaging in oncology has grown rapidly in recent years. 2-[18F]-fluorodeoxyglucose (FDG) is the most common tracer of PET, although drawbacks exist. LÄS MER
5. Hydrodynamics considerations in cells systems from ocean flow to perfusion cultivation process
Sammanfattning : Microorganisms and animal cells are grown surrounded by fluid, which is providing them with nutrients and removing their waste products. In nature and industry processes, cells/microbes can be subject to aggressive environments, such as turbulent flow or shear flow. LÄS MER
