2. 1. Peptide Receptor Radionuclide Therapy in Neuroendocrine Neoplasms : Aspects of tumour characteristics, receptor recycling and peptide mass

   Author : Ulrika Jahn; Anders Sundin; Mark Lubberink; Ulrike Garske-Román; Mona-Elisabeth Rootwelt-Revheim; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuroendocrine tumors; Peptide receptor radionuclide therapy PRRT ; Peptide; Small-Intestinal; Pancreatic; Dosimetry; Somatostatin receptor;

   Abstract : Neuroendocrine neoplasm (NEN) can arise in any part of the body, but most commonly in the lungs, bronchi, and the gastrointestinal tract including the pancreas. They combine neuroendocrine and tissue-of-origin-specific characteristics; explaining different symptoms depending on the organ of origin. READ MORE

4. 2. Antimicrobial Peptide Interactions with Phospholipid Membranes : Effects of Peptide and Lipid Composition on Membrane Adsorption and Disruption

   Author : Adam A Strömstedt; Martin Malmsten; Georges Belfort; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial; peptide; adsorption; liposome; membrane; melittin; cholesterol; tryptophan; phospholipid; bilayer; PHARMACY; FARMACI; Pharmaceutical Physical Chemistry; farmaceutisk fysikalisk kemi;

   Abstract : The interactions between antimicrobial peptides and phospholipid membranes were investigated, in terms of lipid headgroup variations and the role of cholesterol, as well as peptide composition and structure. Also strategies for increasing proteolytic stability were evaluated. READ MORE

5. 3. Amphiphilic Peptide Interactions with Complex Biological Membranes : Effect of peptide properties on antimicrobial and anti-inflammatory effects

   Author : Shalini Singh; Martin Malmsten; Per Hansson; Debora Berti; Uppsala universitet; []
   Keywords : LPS; Antimicrobial; Peptide; Inflammation; Infections; Liposome; Binding; PEG; Farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

   Abstract : With increasing problem of resistance development in bacteria against conventional antibiotics, as well as problems associated with diseases either triggered or enhanced by infection, there is an urgent need to identify new types of effective therapeutics for the treatment of infectious diseases and its consequences. Antimicrobial and anti-inflammatory peptides have attracted considerable interest as potential new antibiotics in this context. READ MORE

6. 4. Microgel Interactions with Peptides and Proteins : Consequence of Peptide and Microgel Properties

   Author : Ronja Widenbring; Martin Malmsten; Per Hansson; Catherine Picart; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Binding; Degradation; Enzyme; Gel; Hydrogel; Microgel; Peptide; Protein; Release; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

   Abstract : Microgels are lightly cross-linked hydrogel particles in the sub-micrometer to micrometer size range with a capacity to drastically change their volume in response to changes in the external environment. Microgels have an ability to bind and store substances such as biomacromolecular drugs, notably proteins and peptides, and release them upon stimuli, making them potential candidates as drug delivery vehicles and functional biomaterials.

7. 5. Development of Peptide Binders : Applied to Human CRP, Carbonic Anhydrase (II, IX) and Lysine Demethylase 1

   Author : Jie Yang; Jan Kihlberg; Morten Grötli; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; polypeptide conjugates; molecular recognition; peptide cyclization; protein targets;

   Abstract : In this thesis, a polypeptide binder concept is illustrated. By conjugation to a set of sixteen polypeptides, a small binding molecule can evolve into a polypeptide binder with increased affinity and selectivity. READ MORE
