2. 1. Myofibroblasts and the Vascular Endothelium : Impact of Fibrin Degradation Products and miRNA on Vascular Motility and Function

   Author : Peder Fredlund Fuchs; Pär Gerwins; Johan Kreuger; Arne Östman; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Angiogenesis; Vascular biology; Chemotaxis; Endothelial cell; Myofibroblast; Wound healing; miRNA; Heparan sulfate; Medical Science; Medicinsk vetenskap;

   Abstract : Angiogenesis is the formation of new blood vessels from pre-existing vasculature and is important during development as well as wound healing and tissue remodeling. Angiogenesis also occurs during pathological conditions such as diabetic retinopathy and cancer. READ MORE

4. 2. Electron microscopy and microanalysis of polymers and polymer blends : artifacts and applications

   Author : Henrik Lindberg; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Abstract : Electron microscopy and microanalysis is used to examine the degradation of unstainable polymers and polymer blends in order to gain an understanding and arrive at methods for characterizing microstructures. Several methods have been used in order to obtain complementary ways of establishing artifacts arising from specimen preparation effects, the internal energy of the components, and degradation under the electron beam together with low or zero contrast between phases in a blend.

5. 3. 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.

6. 4. On Sustainability of Biomass for Energy and the Governance Thereof

   Author : Oskar Englund; Virginia Dale; Chalmers tekniska högskola; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sustainability; land use; spatial modelling; biomass production; certification; environmental legislation; biomass resources; ecosystem services; Bioenergy; GIS; biodiversity; governance;

   Abstract : Due to concerns about climate change, energy security, and resource scarcity, non- renewable resources are increasingly being displaced by biomass. As with most human activities, the production of biobased products can be associated with negative impacts. Primarily, this relates to the biomass supply systems, i.e. READ MORE

7. 5. Mechanical properties of sound and of deteriorated softwood at different length scales : Poromicromechanical modeling and experimental investigations

   Author : Thomas K. Bader; Karin Hofstetter; Kristofer Gamstedt; Austria Vienna University of Technology; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggteknik; Civil engineering; Forestry and Wood Technology; Skog och träteknik;

   Abstract : Due to its natural origin and its inherent heterogeneities, mechanical properties of wood are highly anisotropic and show a broad variability, not only between different wood species, but also within a tree. Similar to other biological materials, the wood mi- crostructure is well organized and hierarchically structured from the annual rings visible to the naked eye down to the wood polymers cellulose, hemicellulose, and lignin at the nanometer-scale.
