  1. 1. Evaluation of Alginate Microcapsules for Use in Transplantation of Islets of Langerhans

    Author : Aileen King; Simon Howell; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Alginate; biocompatibility; cytokines; epimerases; islet transplantation; microencapsulation; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Transplantation of islets of Langerhans is a potential treatment of type 1 diabetes that aims to restore normal glucose homeostasis. Microencapsulation of islets could enable transplantation in the absence of immunosuppression, which would be beneficial as the side effects associated with immunosuppression outweigh the potential benefits of islet transplantation.

  2. 2. Polymer extraction and utilization of brown algal biomass

    Author : Martin Sterner; Ulrica Edlund; Fredrik Gröndahl; Marguerite Rinaudo; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Algae; Saccharina latissima; alginate; brown seaweed; extraction; filament; chelation; gel; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Aquaculture is a field with a world changing potential. The areas at sea are enormous and aquatic cultivations impact both the environment and local ecology far less than land based cultivations. In the realm of algae, abundancies exists of nutrition, water and accessible sunlight, but there is constant shortage of places to dwell. READ MORE

  3. 3. Pulsed Field Gradient NMR Studies of Diffusion in Polymer Gels

    Author : Diana Bernin; Chalmers University of Technology; []
    Keywords : diffusion; gel; alginate; pulsed field gradient NMR; 19F NMR; cellulose; 1H NMR; dendrimer; biomaterial; mass transport;

    Abstract : Soft biomaterials, such as gels, play an important role in different kinds of products and applications, in particular in drug delivery systems, health care products, and food. Polymer gel's great ability to control mass transport is applied on e.g. the uptake of liquids in diapers. READ MORE

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

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

    Abstract : 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. READ MORE

    Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.
