  1. 21. Moisture conditions in rain exposed wood joints - Experimental methods and laboratory measurements

    Författare :Maria Fredriksson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; moisture; durability; service life; microclimate; surface moisture; mositure content; Norway spruce; Picea abies; pressure plate; decay; growth ring width; heartwood;

    Sammanfattning : This thesis concerns the moisture conditions in rain exposed wood structures, i.e. wood exposed to high moisture levels. The focus was on the microclimate (the climate at the wood surface) and the material climate (the wood moisture content) in joints. LÄS MER

  3. 22. The role of the microenvironment in growth plate and articular chondrocyte differentiation

    Författare :Zelong Dou; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : One crucial process during skeletal development is joint formation. It starts with the interzone appearance characterized by high expression of Gdf5, Gli3, Wnt4 and Wnt9a, low expression of Col2a1 of the local compact elongated cells which subsequently give rise to most joint elements including articular cartilage as the ongoing joint cavitation.

  4. 23. Effects of growth factors on chondrocyte proliferation and differentiation

    Författare :Caroline Edwall-Arvidsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Growth plate cartilage; limb buds; growth factors; proliferation; differentiation; collagens; c-fos; ALP;

    Sammanfattning : Longitudinal bone growth is regulated at the level of growth plate chondrocytes by circulating or locally produced hormones and growth factors. Present investigation focused on the effects of growth hormone (GH) and growth factors on chondrocyte proliferation and differentiation during pre- and postnatal cartilage development. LÄS MER

  5. 24. Experimental studies of growth response to hormonal treatment

    Författare :Katja Sundström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Statural growth occurs as a result of the collective growth of long bones and the axial skeleton. Linear bone growth occurs at both ends of the bones in a thin cartilaginous structure termed the growth plate, located between the epiphysis and metaphysis. LÄS MER

  7. 25. Prevention of growth failure caused by glucocorticoid treatment

    Författare :Yunhan Zhao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Children with chronic inflammation often suffer from growth failure and many of these children are treated with high doses of glucocorticoids (GCs). However, the underlying mechanisms of growth failure under conditions of chronic inflammation and the relative contributions of inflammation per se and commonly used GC treatment are still unknown.
