4. 18. Development and characterization of an in vitro method for interaction studies between polymers and pharmaceuticals : Aiding in the development of new drug delivery systems

   Författare :Marcus Wanselius; Per Hansson; Magnus Bergström; Susanna Abrahmsén-Alami; Christian Pedersen; Anna Fureby; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microgels; Subcutaneous administration; Drug delivery; Microfluidics; In vitro methodology; Method development; Biopharmaceuticals; Amphiphilic drugs; Polyelectrolytes; Hyaluronic acid; Peptides; Farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

   Sammanfattning : Polymers are a group of macromolecules used in formulations of pharmaceuticals, one example being the delivery system DC Bead™. Further, some of the most abundant and for drug delivery important constituents of the subcutaneous tissue are charged polymers (polyelectrolytes), e.g. collagen, hyaluronic acid, and chondroitin sulfate.

5. 19. Posterior capsule opacification : An experimental study in vitro and in vivo

   Författare :Niklas Wallentin; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Posterior capsule opacification PCO ; after-cataract; lens epithelial cell; proliferation; aqueous humor AqH ; inflammation; growth factors; basic fibroblast growth factor bFGF ; transforming growth factor-β TGF-β ; extracapsular cataract extraction; corneal incision; rabbit; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; galenisk farmaci; Pharmaceutics;

   Sammanfattning : The clinical and economic significance of posterior capsule opacification (PCO) makes it an important public health problem. A better understanding of the pathogenesis in order to reduce/prevent PCO is needed. For this purpose an experimental model in the rabbit was used and further developed in thisthesis. LÄS MER

7. 20. Role of TLR4 in Escherichia coli urinary tract infection

   Författare :Patrik Samuelsson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; mycology; Mikrobiologi; bakteriologi; serologi; transplantation; Microbiology; virology; bacteriology; Immunologi; serology; Immunology; Pathogen; Mucosa; P-fimbriae; Toll like receptor;

   Sammanfattning : In this thesis we have used P fimbriated E. coli as a model to investigate the mechanisms of bacterial recognition and cell activation by the urinary tract (UT) epithelium. We show that Toll like receptor 4 (TLR4) is crucial for the recognition and host response to P fimbriated E. coli. LÄS MER
