    Sammanfattning : Hydropower is one of the main sources for Sweden’s energy, which is clean and renewable. It is a clean energy source because no fuels are burned which does not pollute the air and it is a renewable energy source as it only uses natural water cycle for generating energy. LÄS MER

  3. 22. Wnt/β-Catenin Signalling in Parathyroid Tumours

    Författare :Peyman Björklund; Gunnar Westin; Göran Åkerström; Tommy Andersson; Uppsala universitet; []
    Nyckelord :Surgery; Hyperparathyroidism; β-catenin; Mutation; Human parathyroid cell line; LRP5; Alternative splicing; Kirurgi;

    Sammanfattning : Primary hyperparathyroidism (pHPT) due to parathyroid tumours with hypersecretion of parathyroid hormone and hypercalcaemia is a common disease with incompletely understood etiology affecting more than 1 % of the population, primarily postmenopausal women. In secondary hyperparathyroidism (sHPT), parathyroid tumours develop in response to calcium and vitamin D deficiency generally in patients with uraemia. LÄS MER

    Sammanfattning : When a couple moves, the woman is often placed at a disadvantage. Moves are more often motivated by men’s career advancement opportunities, and men tend to gain more economically from moving. In this thesis, these patterns are examined with an eye on the role of sex segregation on the labor market. LÄS MER
