  1. 21. Effects of Dopamine Signaling on Recovery and Inflammation after Ischemic Stroke

    Författare :Enida Kuric; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Ischemic stroke, resulting from occlusion of a brain artery is the most common type of stroke with a prevalence of 15 million people and the leading cause of long-term disability worldwide. Importantly, partial spontaneous recovery of lost neurological functions occurs mainly during the first months after stroke onset, albeit to a limited extent. LÄS MER

  3. 22. Flight strategies in migrating birds: when and how to fly

    Författare :Martin Green; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geese; waders; terns; Animal ecology; Djurekologi; wind tunnel; radio telemetry; satellite telemetry; radar; formation flight; flight speed adjustment; wind drift; energy savings; departure decisions; bird migration; wind;

    Sammanfattning : Wind has a profound influence on migrating birds since it inevitably will influence travel time and energy expenditure. In this thesis I investigate how migrating birds are affected by, and use winds. LÄS MER

  4. 23. Gene regulatory evolution in flycatchers: statistical approaches for the analysis of allele-specific expression

    Författare :Mi Wang; Hans Ellegren; Christopher Wheat; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ASE; gene expression evolution; bayesian; RPASE; flycatcher.; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Understanding the molecular mechanisms underlying evolutionary changes in gene expression is a major research topic in biology. While a powerful approach to study this is the analysis of allele-specific expression (ASE), most of previously published methods can only be applied to lab organisms. LÄS MER

  5. 24. Mining DNA elements involved in targeting of chromatin modifiers

    Författare :Philge Philip; Per Stenberg; Jan Larsson; Stein Aerts; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nucleosome; histone; chromatin; chromatin modifiers; targeting; DNA motifs; protein factors; MSL; molekylärbiologi; Molecular Biology;

    Sammanfattning : Background: In all higher organisms, the nuclear DNA is condensed into nucleosomes that consist of DNA wrapped around a core of highly conserved histone proteins. DNA bound to histones and other structural proteins form the chromatin. LÄS MER

  7. 25. The cost of phasing out coal: Identifying and overcoming socio-political barriers

    Författare :Lola Nacke; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Feasibility; Energy transitions; Coal phase-out; Socio-political feasibility;

    Sammanfattning : IPCC climate mitigation scenarios project rapid coal phase-out as an integral part of climate change mitigation. Despite the diffusion of cost competitive low-carbon alternatives to coal power, some argue that current decline is not in line with climate mitigation targets, and that rapid coal phase-out depicted in climate scenarios is not socio-politically feasible.
