  2. 1. Moisture Buffering in the Indoor Environment

    Author : Kaisa Svennberg; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; furniture; textiles; moisture buffering; beds; indoor air; indoor environment; sorption isotherms; field measurements; definition scheme; Technological sciences;

    Abstract : Moisture buffering in the indoor environment is the ability, through absorption and desorption, of surface materials to attenuate the moisture variations of the indoor air. Moisture buffering plays an important role in understanding the risks for biological growth in surface materials in the indoor environment, e.g. READ MORE

  4. 2. In vivo evaluations of the neutralizing effect of a hydroxyl ion-releasing resin composite and a prophylactic gel on plaque acidogenicity : measured by the microtouch method

    Author : Anitha Persson; Jan van Dijken; Peter Lingström; Anette Oliveby; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caries; clinical; buffering; elderly; plaque pH; resin composite; restorations; microorganisms; ODONTOLOGY; ODONTOLOGI;

    Abstract : The prevalence of dental caries has decreased dramatically in most developed countries since the sixties and the number of remaining teeth in adults has increased during the last decades. Elderly as a group will during aging become an increasing risk group for caries. READ MORE

  5. 3. Aneuploidy compensatory mechanisms and genome-wide regulation of gene expression in Drosophila melanogaster

    Author : Lina Lundberg; Jan Larsson; Brian Oliver; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genome-wide gene regulation; aneuploidy; buffering; HP1a; POF; SETDB1; Su var 3-9; MSL; roX; genetik; Genetics;

    Abstract : Stimulation or repression of gene expression by genome-wide regulatory mechanisms is an important epigenetic regulatory function which can act to efficiently regulate larger regions or specific groups of genes, for example by compensating for loss or gain of chromosome copy numbers. In Drosophila melanogaster there are two known chromosome-wide regulatory systems; the MSL complex, which mediates dosage compensation of the single male X-chromosome and POF, which stimulates expression from the heterochromatic 4th chromosome.

  6. 4. Chromosome-specific adaptations of RNA stability and the roles of the roX RNAs in dosage compensation

    Author : Marie-Line Faucillion; Jan Larsson; Jean-Yves Roignant; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; dosage compensation; buffering; RNA stability; RNA decay; RNA half-life; RNA-seq; genome-wide; sex chromosomes; evolution; roX1; roX2; POF; MSL; molekylärbiologi; Molecular Biology;

    Abstract : Sex chromosomes evolved from an ancient pair of autosomes and the Y chromosome lost most of its genetic information in the process. This created two kinds of genomic imbalances: the first one between males (XY) and females (XX) and the second one between the sex chromosomes and the autosomes (X:AA). READ MORE
