  2. 1. Chemical Modification of Cellulose Fibres and Fibrils for Design of New Materials

    Author : Verónica López Durán; Lars Wågberg; Per A. Larsson; Akira Isogai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; borohydride reduction; cellulose-based materials; chemical modification; chlorite oxidation; fibres; fibrils; periodate oxidation; TEMPO oxidation; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Due to the growing interest in biobased materials in today’s society, where the need for a cyclic economy is obvious, there has been a huge increase in the  interest for using cellulose due to its excellent mechanical and chemical properties. However, the properties of cellulose have to be modified and improved in order to satisfy advanced material applications where the cellulose properties can be tuned to fit the properties of other components in composite mixtures.

  4. 2. Synthesis of Ring-fused Peptidomimetics : Interacting with Amyloid Fibrils

    Author : Dan E. Adolfsson; Fredrik Almqvist; Anna Linusson; Morten Grötli; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic chemistry; synthesis; peptidomimetics; thiazoline fused 2-pyridones; Alzheimer s disease; Parkinson s disease; Amyloid; Amyloid-beta; alfa-Synuclein; method development; organisk kemi; Organic Chemistry;

    Abstract : Parkinson's and Alzheimer's disease are the two most common neurological disorders in humans. Both conditions involve progressive death of neurons in the central nervous system, decline in bodily functions and eventually (and invariably), death. So far, no cure exists and the available treatments can only ease symptoms. READ MORE

  5. 3. alpha-synuclein: amyloid fibrils and interactions with lipid membranes

    Author : Marija Dubackic; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; alpha-synuclein; model lipid membranes; amyloid fibrils; Parkinson s disease; Lewy bodies; SANS; SAXS;

    Abstract : The second most common neurodegenerative disease, Parkinson’s disease, is linked with an amyloid forming protein, alpha-synuclein. Hallmarks of Parkinson’s disease are progressive loss of dopaminergic neurons and accumulation of intraneuronal inclusions termed Lewy bodies. READ MORE

  6. 4. Amyloids here, amyloids there…What’s wrong with them?

    Author : Anna Gharibyan; Ludmilla Morozova-Roche; Tuomas Knowels; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amyloids; oligomers; fibrils; cytotoxicity; Alzheimer s disease; Aortic stenosis; S100A9; medicinsk biokemi; Medical Biochemistry;

    Abstract : Amyloid formation is inherent property of proteins which under certain circumstances can become a pathologic feature of a group of diseases called amyloidosis. There are about 30 known human amyloidosis and more than 27 identified proteins involved in these pathologies. READ MORE

  7. 5. Preparation and Application of Functionalized Protein Fibrils

    Author : Fredrik Bäcklund; Niclas Solin; Olle Inganäs; Christofer Lendel; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Many proteins have an innate ability to self-assemble into fibrous structures known as amyloid fibrils. From a material science perspective, fibrils have several interesting characteristics, including a high stability, a distinct shape and tunable surface properties. READ MORE
