  2. 1. Selective inhibition of acetylcholinesterase 1 from disease-transmitting mosquitoes : design and development of new insecticides for vector control

    Author : Cecilia Engdahl; Anna Linusson; Fredrik Ekström; Zoran Radić; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acetylcholinesterase; non-covalent inhibitor; vector control; insecticide; mosquito; vector-borne disease; high throughput screening; rational design; biokemi; Biochemistry; datorlingvistik; computational linguistics;

    Abstract : Acetylcholinesterase (AChE) is an essential enzyme with an evolutionary conserved function: to terminate nerve signaling by rapid hydrolysis of the neurotransmitter acetylcholine. AChE is an important target for insecticides. READ MORE

  4. 2. Towards Mosquitocides for Prevention of Vector-Borne Infectious Diseases : discovery and Development of Acetylcholinesterase 1 Inhibitors

    Author : Sofie Knutsson; Anna Linusson; Fredrik Almqvist; Andreas Larsson; Ulf Nilsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mosquito; vector-borne diseases; vector control; insecticide; acetylcholinesterase; medicinal chemistry; high-throughput screening; organic synthesis; homology modeling; structure activity relationship; structure selectivity relationship; datorlingvistik; computational linguistics; organisk kemi; Organic Chemistry;

    Abstract : Diseases such as malaria and dengue impose great economic burdens and are a serious threat to public health, with young children being among the worst affected. These diseases are transmitted by mosquitoes, also called disease vectors, which are able to transmit both parasitic and viral infections. READ MORE

  5. 3. Ecological effects of pesticides in freshwater model ecosystems

    Author : Lina Wendt-Rasch; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marine biology; aquatic ecology; limnology; Marinbiologi; Hydrobiology; community; zooplankton; algae; herbicide; insecticide; pesticide mixture; macrophytes; cypermethrin; metsulfuron-methyl; risk assessment; pesticides; microcosms; limnologi; akvatisk ekologi;

    Abstract : In this thesis I have investigated the effects of pesticide exposure on the ecosystem level using various types of experimental ecosystems, i.e. microcosms. The direct effect of exposure to cyperemthrin, a pyretroid insecticide, was a rapid decrease of crustancean zooplankton in enclosures in a lake. READ MORE

  6. 4. Structure and function of microbial communities in constructed wetlands - influence of environmental parameters and pesticides on denitrifying bacteria

    Author : Susann Milenkovski; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fungicide; concentration-response curves; nosZ; nirS; nirK; bacterial activity; denitrification; bacterial community composition; herbicide; insecticide;

    Abstract : This thesis addresses the interactions and relationships between natural aquatic bacterial communities, environmental parameters, anthropogenic chemicals and the denitrification pathway in the habitat of agricultural constructed wetlands. The main aim was to gain fundamental knowledge of the drivers behind the processes of the denitrification (i.e. READ MORE

  7. 5. Pesticide use in rice farming and its impacts on climbing perch (Anabas testudineus) in the Mekong Delta of Vietnam

    Author : Thanh Tam Nguyen; Håkan Berg; Michael Tedengren; Cong Van Nguyen; Joachim Sturve; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mekong Delta; Rice field; Climbing perch; Insecticide; Chlorpyrifos ethyl; Fenobucarb; Mixture; Sequential applications; AChE; Physical Geography; naturgeografi;

    Abstract : The intensification of agricultural production in the Mekong Delta has faced serious challenges with respect to increased use of agrochemicals and especially pesticides. The indiscriminate use of pesticide could potentially impact on the long-term food production, environmental and human health in the delta. READ MORE
