  2. 1. Quantitative Tracer Based MRI Perfusion : Potentials and Limitations

    Author : Arvid Morell; Atle Bjørnerud; Håkan Ahlström; Linda Knutsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; Perfusion; Contrast agent; Relaxivity; Radiology; Radiologi;

    Abstract : 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. READ MORE

  4. 2. Tools for the development of intensified perfusion processes for mammalian cell culture

    Author : Hubert Schwarz; Véronique Chotteau; Mark Smales; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recombinant protein biomanufacturing; Perfusion process; Integrated continuous bioprocessing; Monoclonal antibody; Erythropoietin; Chinese Hamster Ovary cells; Human Embryonic Kidney cells; Perfusion medium optimization; Cell specific perfusion rate; Raman spectroscopy; N-glycosylation; Microbioreactors; Design of Experiments; Biotechnology; Bioteknologi;

    Abstract : 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. READ MORE

  5. 3. The effect of mechanical ventilation on abdominal organs : Analysing the role of PEEP and perfusion

    Author : Silvia Marchesi; Miklós Lipcsey; Anders Larsson; Göran Hedenstierna; Torbjörn Karlsson; Anders Oldner; Ragnvi Hagman; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ARDS; sepsis; abdominal inflammation; edema; perfusion; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : 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. READ MORE

  6. 4. Radiolabeled acetate PET in oncology imaging : studies on head and neck cancer, prostate cancer and normal distribution

    Author : Aijun Sun; Jens Sörensen; Silvia Johansson; Mikael Karlsson; Katrine Åhlström Riklund; Ingela Turesson; Heikki Minn; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 11C-acetate; 18F-fluoroacetate; PET; head and neck cancer; staging; delineating tumor volume; clearance rate; perfusion; RT; treatment outcome; benign and malignant lymph node; prostate cancer; normal distribution; Oncology; Onkologi; onkologi; Oncology;

    Abstract : 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. READ MORE

  7. 5. Hydrodynamics considerations in cells systems from ocean flow to perfusion cultivation process

    Author : Caijuan Zhan; Véronique Chotteau; Jeffrey Chalmers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microorganism; cells; hydrodynamics; turbulence; numerical simulation; CFD; Resonance; Wave bioreactor; ATF; TFF; perfusion; design feeding strategy; Bioteknologi; Biotechnology;

    Abstract : 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. READ MORE
