  1. 21. Effects of plasticizing and crosslinking on the mechanical and barrier properties of coatings based on blends of starch and poly(vinyl alcohol)

    Författare :Asif Javed; Lars Järnström; Henrik Ullsten; Peter Rättö; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Citric acid; Glycerol; Polyethylene glycol; Barrier properties; Starch; Mechanical properties; Polyvinyl alcohol; Adhesion; Cross linking; Extrusion coating; Chemical Engineering; Kemiteknik;

    Sammanfattning : In the last decades, intensive research has been carried out in order to replace oil-based polymers with bio-based polymers due to growing environmental concerns. So far, most of the barrier materials used in food packaging are petroleum-based materials. LÄS MER

  3. 22. Endothelial Barrier Dysfunction in Multiple Organ Injury. An Experimental Study in Rats

    Författare :Xiaoming Deng; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; Endothelial barrier permeability; Multiple organ dysfunction syndrome; Zymosan; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Multiple organ dysfunction syndrome (MODS) is still the leading cause of mortality in the surgical intensive care unit. The effect on among others endothelial barrier permeability, reticuloendothelial function, organ function and protease-antiprotease activities was studied following a variety of challenges, especially over-activation of macrophages induced by intraperitoneal administration of zymosan.

  4. 23. Physiological aspects of the glomerular filtration barrier

    Författare :Kristinn Sverrisson; Njurmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Proteinuria is associated with progression of kidney disease and is an independent risk factor for cardiovascular morbidity and mortality. The pathophysiological alterations resulting in proteinuria are obscure, although proteinuria is often associated with pathological changes in the glomerular filtration barrier (GFB). LÄS MER

  5. 24. Chronic stress and intestinal barrier function: Implications for infection and inflammation in intensive salmon aquaculture

    Författare :Henrik Sundh; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Intestinal barrier function; stress; cortisol; Ussing chamber; welfare; health; inflammation; neutrophils; cytokines; chronic stress;

    Sammanfattning : Aquaculture is a fast growing food-producing sector worldwide. This has increased the awareness among the public as well as governments of the need to secure the welfare and health of farmed fish. Atlantic salmon is, in non-Asian countries, one of the most successful aquacultured species. LÄS MER

  7. 25. Effects of plasticizing and crosslinking on coatings based on blends of starch-PVOH and starch-lignin

    Författare :Asif Javed; Henrik Ullsten; Peter Rättö; Lars Järnström; Douglas Bousfield; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Citric acid; Glycerol; Polyethylene glycol; Barrier coatings; Starch; Lignin; Mechanical properties; Poly vinyl alcohol ; Creasing; Adhesion; Cross-linking; Extrusion coating; Chemical Engineering; Kemiteknik;

    Sammanfattning : A barrier material is usually needed on a fiber-based food package to protect the packed food from gases and moisture and thus maintain its quality. Barrier materials presently used in food packaging applications are mostly petroleum-based polymers. LÄS MER
