2. 1. Insights into Covalent Chemistry for the Developmen­t of Biomaterials

   Author : Daniel Bermejo-Velasco; Oommen P. Varghese; Jöns Hilborn; Frey Holger; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hyaluronic acid; hydrogel; biomaterials; covalent chemistry; biomedical applications; MRI; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

   Abstract : Covalent cross-linking chemistry is currently exploited in the preparation of biomaterial for biomedical applications. Choice of these chemistries for the preparation of biomaterials and bioconjugates strongly influences the biological output of these materials. READ MORE

4. 2. Composite Regenerative Scaffolds

   Author : Elle Edin; Jöns Hilborn; May Griffith; Alicia El Haj; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nerve; neurite; regeneration; PEDOT; PEDOT:Tosylate; electrostimulation; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

   Abstract : Regenerative medicine and tissue engineering solutions of heavily innervated tissues are at this point lacklustre. This thesis expands our knowledge of appropriate acellular scaffolds for tissue repair in general and nerve regeneration in particular. READ MORE

5. 3. Evaluation of Functionalized Biopolymers as a Step Toward Targeted Therapy of Osteoporosis

   Author : Sujit Kootala; Jöns Hilborn; Peter Thomsen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Osteoporosis; Bone regeneration; Biomaterials; Hyaluronic acid; Bisphosphonates; Osteoclasts; Osteoblasts; Growth factors; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : The work presented in this thesis focuses on the development of strategies and smart bioactive materials for the treatment of osteoporosis. High and low molecular weight soluble hyaluronic acid-bisphosphonate (HA-BP) derivatives were investigated for their ability to inhibit osteoclasts. READ MORE

6. 4. Functional Cyclic Carbonate Monomers and Polycarbonates : Synthesis and Biomaterials Applications

   Author : Jonas Mindemark; Tim Bowden; Andrew Dove; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA condensation; gene delivery; ionomers; polyplexes; self-assembly; amphiphiles; biodegradable; biological applications of polymers; transfection; cyclic carbonate monomers; polycarbonates; semicrystalline polymers; click chemistry; triazoles; cycloaddition; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

   Abstract : The present work describes a selection of strategies for the synthesis of functional aliphatic polycarbonates. Using an end-group functionalization strategy, a series of DNA-binding cationic poly(trimethylene carbonate)s was synthesized for application as vectors for non-viral gene delivery. READ MORE

7. 5. Regulating Gene Expression to Promote Osteoblastic Differentiation of Stem Cells

   Author : Maruthibabu Paidikondala; Oommen P. Varghese; Jöns Hilborn; Laura Creemers; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

   Abstract : Bone is a tissue that heals by itself, unless the defect is too large (critical size). Today, novel regenerative medicine approaches have emerged as an alternative to treat such defects. This thesis explores alternative therapeutic strategies for bone tissue engineering which are biocompatible and clinically translatable. READ MORE
