  2. 1. Signaling pathways in Drosophila immunity

    Author : Shiva Seyedoleslami Esfahani; Ylva Engström; Steven Wasserman; Stockholms universitet; []
    Keywords : Drosophila immunity; signaling pathways; Cactus; NFκB; Molecular Biology; molekylärbiologi;

    Abstract : Drosophila relies on innate immunity to protect itself from its hostile environment throughout its life cycle. Despite the remarkable progress in understanding many aspects of Drosophila immunity, there are still big gaps in our knowledge. READ MORE

  4. 2. Regulatory proteins and the regulation of immune response in Drosophila melanogaster

    Author : Erik Roos; Åsa Rasmuson-Lestander; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Abstract : Insect antibacterial peptides are regulated at the transcriptional level. The otherwise silent antibacterial Cecropin genes are strongly induced upon bacterial challenge. READ MORE

  5. 3. On Approximating Asymmetric TSP and Related Problems

    Author : Anna Palbom; Mikael Goldmann; Lars Engebretsen; Peter Jonsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Komplexity theory; algorithms; approxiamtion; Computer science; Datalogi;

    Abstract : In this thesis we study problems related to approximation of asymmetric TSP. First we give worst case examples for the famous algorithm due to Frieze, Gabiati and Maffioli for asymmetric TSP with triangle inequality. Some steps in the algorithm consist of arbitrary choices. To prove lower bounds, these choices need to be specified. READ MORE

  6. 4. Morphologican and functional studies on the Drosophila neuromuscular system during postembryonic stages

    Author : Ana Beramendi; Rafael Cantera; Prof. Carlos Dotti; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drosophila; neuromuscular system; Rel-proteins; fly brain; rhythmic morphology; aging; ; Neurobiology; Neurobiologi;

    Abstract : The nervous system of the fruit fly Drosophila melanogaster has emerged as an excellent model for fundamental neuroscience as well as for biomedical research of human neurological diseases. In this thesis, two aspects of the neuromuscular system have been investigated: the role of the IkB-protein Cactus in the larval neuromuscular junction and the morphology of motor terminals throughout adult life.

  7. 5. Genetic Adaptation and Speciation in Darwin’s Finches and Atlantic Herring

    Author : Fan Han; Leif Andersson; Kjetill Sigurd Jakobsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Darwin s finches; Atlantic herring; Population genetics; Evolution; Ecological adaptation; Speciation; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Bioinformatics; Bioinformatik;

    Abstract : Natural selection acts on existing genetic variation to drive genetic adaptation of organisms to various ecological niches. Interaction between closely related populations, through processes such as competition and hybridization, may either lead to their divergence or population fusion, which has consequences for adaptation and the formation of species.
