  1. 1. Identification and Syntheses of Semiochemicals Affecting Mnesampela privata and Trioza apicalis

    Author : Anna Nilsson; Erik Hedenström; Anna-Karin Borg-Karlsson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mnesampela privata; semiochemicals; pheromones; kairomones; 3Z; 6Z; 9Z -3; 6; 9-nonadecatriene; 3Z; 6Z; 9Z -3; 6; 9-heneicosatriene; carrot psyllid; Trioza apicalis; Organic chemistry; Organisk kemi;

    Abstract : The Autumn gum moth, Mnesampela privata (Lepidoptera: Geometridae) is an endemic Australian moth whose larvae feed upon species of Eucalyptus. The moths favorite host plants are E. globulus and E. nitens which are the most important species used in commercial plantations of the Australian pulpwood industry. READ MORE

  2. 2. Nutri-medicinal plants used in the management of HIV/AIDS opportunistic infections in western Uganda : documentation, phytochemistry and bioactivity evaluation

    Author : Savina Asiimwe; Anna Karin Borg Karlsson; Jasper Ogwal-Okeng; KTH; []
    Keywords : Ethnobotanical study; Medicinal plants; HIV; AIDS; opportunistic infections; bacteria; fungi; GC-MS; phytochemistry; SPME; antioxidant; histopathology; biochemistry; hematology; western Uganda.; Kemi; Chemistry;

    Abstract : As a result of the AIDS epidemic, many people are immunocompromised and opportunistic infections are common. Medicinal plants constitute one of the fundaments of HIV treatment and are commonly used in management of HIV–related ailments, and also to counteract the side effects of antiretroviral therapy.

  3. 3. Purification, Stereoisomeric Analysis and Quantification of Biologically Active Compounds in Extracts from Pine Sawflies, African Butterflies and Orchid Bees

    Author : Joakim Bång; Erik Hedenström; Kristina Sjödin; Hans-Erik Högberg; Anna-Karin Borg-Karlsson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Semiochemicals; sex pheromone; pine sawflies; Bicyclus; Euglossa; chiral separation; derivatisation; GC-­MS; Organic chemistry; Organisk kemi;

    Abstract : Stereochemistry plays an important role in nature because biologically important molecules such as amino acids, nucleotides and sugars, only exist in enantiomerically pure forms. Semiochemicals carry messages, between the same species (pheromones) and between different species (allelochemicals). READ MORE

  4. 4. Environmental and health aspects of corrosion– importance of chemical speciation

    Author : Yolanda Hedberg; Inger Odnevall Wallinder; Anna Karin Borg Karlsson; Susanna Wold; KTH; []
    Keywords : ;

    Abstract : During the last decades, the interest in corrosion of metals and alloys from an environmental and health perspective has increased rapidly as a consequence of stricter environmental and human exposure legislations, their extensive use as implant materials and an increasing understanding related to occupational and/or daily exposure to airborne particles. Corrosion-induced metal release, however, needs to be understood in detail and to include knowledge related to chemical speciation, i. READ MORE

  5. 5. Solid-phase Microextraction and Detection of Organophosphate Triesters in Indoor air

    Author : Sindra Isetun; Ulrika Nilsson; Anna-Karin Borg-Karlsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SPME; Organophosphate triesters; flame-retardant; indoor air; Analytical chemistry; Analytisk kemi;

    Abstract : In the work underlying this thesis solid-phase microextraction (SPME) was evaluated as a passive sampling technique for organophosphate triesters in indoor air. These compounds are used on a large scale as flame-retarding and plastizicing additives in a variety of materials and products, and have proven to be common pollutants in indoor air. READ MORE
