  2. 11. Is genetic diversity more important for terpene emissions than latitudinal adaptation? : Using genetically identical trees to better understand emission fluctuations across a European gradient

    Author : Ylva van Meeningen; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BVOC; English oak; European beech; Norway spruce; genetic diversity; European gradient;

    Abstract : Biogenic volatile organic compounds (BVOCs) are trace gases other than CO2 and CH4 produced and emitted by the vegetation. The group consists of thousands of compounds in various shapes and sizes and with short atmospheric lifetimes. Some of the most common BVOC groups are called isoprene, monoterpenes and sesquiterpenes. READ MORE

  4. 12. Carbonaceous Aerosol in Europe - out of the woods and into the blue?

    Author : Jan Robert Bergström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic aerosol; elemental carbon; chemical transport modelling; residential wood combustion; biotic stress induced emissions; source apportionment; EMEP MSC-W model;

    Abstract : Particulate matter (PM) in the atmosphere influences weather and climate and may have important health impacts. Regional scale chemical transport modelling aims to describe the composition of particulate matter, to track different sources, estimate their relative importance, and to give realistic predictions of responses to changes in emissions and atmospheric conditions.

  5. 13. Terpenoid Plant Metabolites - Structural Characterization and Biological Importance

    Author : Eliana Maldonado; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Terpenoid Sesquiterpene lactones Breast-cancer cell lines Cytotoxicity Antileishmanicial Structural characterization;

    Abstract : In response to the challenges of their local environments, organisms produce of a large number of chemical diverse compounds with complex stereochemistry and reactive functional groups. These characteristics enable them to interact and bind specifically to biological target molecules and exert various biological activities, and have assured that Natural products continues to be an important source of bioactive compounds, which, for example, facilitate the search for new lead structures that can be developed into new pharmaceuticals.

  6. 14. Ugandan medicinal plants used traditonally for oral care : investigation of extracts for anti-bacterial, cytotoxic and anti-inflammatory effects

    Author : Francis Ocheng; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Medicinal plants;

    Abstract : The use of traditional medicine for treating human diseases remain widespread in low-resource settings. Medicinal plants form the backbone for traditional medicine systems in many parts of the world. In Uganda, most communities rely on medicinal plants to prevent and treat oral diseases. READ MORE
