    Sammanfattning : Throughout the world, the large-scale use of pesticides in agriculture is an area of concern due to known harmful effects on human and environmental health. Mixtures of different pesticides are found in lakes and streams, where their presence endangers aquatic organisms, like benthic algae, and the ecosystem services they provide. LÄS MER

  3. 7. Ascophyllym Nodosum – påverkan på det orala placket och dess proteaser

    Master-uppsats, Malmö högskola/Odontologiska fakulteten (OD)

    Författare :Nurda Schwech; Sanja Krupic; [2013]
    Nyckelord :Ascophyllum Nodosum; biofilm formation; dental calculus; dental pellicle; dental plaque; fluorometer; protease;

    Sammanfattning : Syfte: Syftet med denna studie var att studera huruvida algen Ascophyllum Nodosum (AN) utövar någon effekt på proteasaktivitet i oralt plack, samt om effekten finns i algen från början eller om man måste inta den oralt för att få en systemisk effekt.En förhöjd proteasaktivitet har förknippats med gingivit och parodontit.

    Sammanfattning : An evaluation of the ecological status of 23 small water reservoirs in Burkina Faso was made in 2004 by IRD (Institut de Recherche pour le Développement), Large dominance of cyanobacteria in some of the reservoirs was one of the signs of an imbalance in the ecology of the water (Cecchi et al. 2005).
