Intracellular accumulation of secreted proteoglycans inhibits cationic lipid-mediated gene transfer. Co-transfer of glycosaminoglycans to the nucleus

Molecules secreted by potential target cells may interfere with cationic lipid-mediated gene transfer. This has been studied using human lung fibroblasts and human epidermoid lung cancer cells. Secreted cell medium components caused a substantial decrease both in the uptake of cationic lipid-DNA complexes (2-4-fold) and in reporter gene expression (100-1000-fold). Metabolic labeling of the cell me

Objects as Links Between Person and Place

In a recently conducted interview study, some survivors of traffic victims rate their home as the most important place for remembrance, compared to both the accident site and the burial plot. The reason for this evaluation appears to be the place’s ability to bring about a positive presence of the deceased. Supported by photographs and personal objects, the home serves as a constant reminder, and

Treatment of textile wastewaters using combinations of biological and physico-chemical methods

Popular Abstract in Swedish En vän till mig berättade hur hon hade köpt en färgglad t-shirt vid en resa till Indien. Första gången hon hade den på sig började det att ösregna och ett par minuter senare fanns det snopet nog mer färg i de kringliggande vattenpölarna än i tyget. Lyckligtvis har de flesta färger idag bättre kvalitet än så. De färger som används inom textilindustrin är utvecklade för aConsiderable amounts of water and chemicals are used in the textile industry, and the presence of dyes in the wastewater is a problem of environmental concern. Synthetic dyes are designed to resist light, water and chemicals to improve the quality of the textiles; however, these properties also contribute to their persistence in the environment. The existence of wastewater treatment plants in conn

Visualization of Ergonomic Guidelines – Development and Evaluation of Prototypes

This study attempts to discover how ergonomic guidelines should be visualized in order to make it easier and more interesting to find and interpret the guidelines throughout the construction process. A prototype, visualizing ergonomic guidelines on the intranet, has been developed and evaluated at a company that produces cars for the global market. The results show that the visualization of ergono
