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

    Författare :Ronja Widenbring; Martin Malmsten; Per Hansson; Catherine Picart; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  2. 2. On the colloidal and molecular aspects of peptide self-assembly

    Författare :Axel Rüter; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Peptide self-assembly; Aggregation kinetics; Peptide hydrogel; Small angle scattering; Rheology;

    Sammanfattning : Peptide self-assembly is a spontaneous process, ubiquitous in nature for the creation of highly ordered and complex biological structures, making it a sought after technique in the development of novel biocompatible materials. The process is also strongly associated with various neurodegenerative diseases in the formation of amyloid plaques in diseases such as Alzheimer’s and Parkinson’s, where fully functioning proteins aggregate are reassembled into nonfunctional fibrillar aggregates that eventually lead to cell death.

  3. 3. Antibacterial elastomeric materials for biomedical applications

    Författare :Annija Stepulane; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogels; antibacterial coating; polydimethylsiloxane; elastomer blends; drug-delivery; antimicrobial peptides;

    Sammanfattning : An ageing population in combination with scientific and clinical advancements have led to a steady increase in the use of medical devices. Elastomeric biomaterials – materials displaying rubber-like mechanics – have found widespread applicability in the production of both short- and long-term medical devices. LÄS MER

  4. 4. Modular Enzyme-Responsive Polysaccharide-Based Hydrogels for Biofabrication

    Författare :Sajjad Naeimipour; Daniel Aili; Robert Selegård; Alireza Dolatshahi-Pirouz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D cell-culture; Bioprinting; Alginate; Hyaluronan; Cancer model;

    Sammanfattning : Engineered human tissue and disease models can decrease the cost and time of developing new drugs and treatments, facilitate personalized medicine, and eliminate the need for animal models that poorly represent the human body and are ethically problematic. However, the current conventional cell expansion methods using 2D culture flasks cannot enable the development of such complex multi-cellular 3D models. LÄS MER

  5. 5. Development of biosynthetic conduits for peripheral nerve repair

    Författare :Aleksandra McGrath; Liudmila N Novikova; John Haycock; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biosynthetic conduit; Mesenchymal stem cells; Nerve graft; Nerve tissue engineering; Peripheral nerve injury; Schwann cells;

    Sammanfattning : Peripheral nerve injuries are often associated with significant loss of nervous tissue leading to poor restoration of function following repair of injured nerves. Although the injury gap could be bridged by autologous nerve graft, the limited access to donor material and additional morbidity such as loss of sensation and scarring have prompted a search for biosynthetic nerve transplants.
