  1. 1. Epigenetic Control of Mammalian Development : Studies on an imprinting control region

    Författare :Liang Liu; Pärt Peterson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Epigenetic; Genomic imprinting; DNA methylation; Igf2; H19; Insulator; CTCF; Imprinting control region; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; zoologisk utvecklingsbiologi; Animal Development;

    Sammanfattning : A subset of autosomal genes is preferentially or exclusively expressed from one of the parental alleles. This phenomenon, termed genomic imprinting, is highlighted by the neighboring Igf2 and H19 genes, which are monoallelically expressed on opposite parental chromosomes. These features are governed by a 2. LÄS MER

  2. 2. Planning and Operation of Large Amounts of Wind Power in a Distribution System

    Författare :Shemsedin Nursebo; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost benefit analysis; coordination.; distribution system; active management strategies; control; integration issues of wind power; frequency of tap change;

    Sammanfattning : The global installed capacity of wind power has shown a significant growth, from 24 GW in 2001 to 370 GW in 2014. The trend shows that an increasing capacity of wind power is being connected to the electric power system. LÄS MER

  3. 3. Costa Rican coffee and bananas : A social-ecological study of management practices and their effects on the environment

    Författare :Angelina Sanderson Bellamy; Micheal Tedengren; Charles Francis; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Costa Rica; coffee; banana; production system; pesticides; organic; conventional; Rainforest Alliance certification; Biology; Biologi; Marine Ecotoxicology; marin ekotoxikologi;

    Sammanfattning : This thesis investigates the variability in management practices on coffee and banana farms in an attempt to identify practices that reduce the environmental impact of export crop production. Different banana production systems are studied to determine their level of environmental impact. LÄS MER

  4. 4. Molecular Studies of Mast Cell Migration and Apoptosis : Two Ways of Regulating Mast Cell Numbers at Sites of Inflammation

    Författare :Jessica Alfredsson; Gunnar Nilsson; Hans-Uwe Simon; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; mast cell; SCF; IL-3; FcεRI; migration; apoptosis; Bim; Bcl-2; Bcl-XL; Akt; FOXO; MAPK; Patologi; Pathology; Patologi;

    Sammanfattning : Upon activation mast cells release numerous proinflammatory mediators. With this feature, mast cells play an important role in host defense against pathogens, and are involved in tissue remodeling and wound healing. However, in cases of excessive inflammation the effects of mast cells are detrimental. LÄS MER

  5. 5. Exploration of bacteria associated with Anopheles mosquitoes around the world : For the prevention of transmission of malaria

    Författare :Louise K. J. Nilsson; Olle Terenius; Staffan Svärd; Sebastian Håkansson; Michael Strand; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; microbiota; microbiome; vector-borne disease; 16S rRNA gene; amplicon sequencing; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Every year, hundreds of thousands of people die from malaria. Malaria is a disease caused by parasites, which are spread by female vector mosquitoes of the genus Anopheles. Current control measures against malaria are based on drugs against the parasites and vector control using insecticides. LÄS MER
