1. 1. Lymphatic Vascular Morphogenesis : From Progenitors to Functional Vessels

   Författare :Nina Daubel; Taija Mäkinen; Markus Affolter; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lymphatic vasculature; morphogenesis; lymphvasculogenesis; mesentery; lymphatic capillary;

   Sammanfattning : The lymphatic vasculature is an important part of the circulatory system and crucial for normal functioning and maintenance of tissues. Yet, our understanding of the processes underlying lymphatic development and homeostasis are surprisingly limited. LÄS MER

3. 2. Preservation of parathyroid function in thyroid and parathyroid surgery

   Författare :Stefan Ander; Göran Åkerström; Linköpings universitet; []
   Nyckelord :Human parathyroid glands; vascular supply; parathyroid preservation; laser Doppler flowmetry; iPTH; autotransplantation; xenotransplantation; a thymic mice; angiogenesis; immunohistochemistry; electron microscopy; ultrastructure; autoradiography; MEDICINE; MEDICIN;

   Sammanfattning : Preservation of normal parathyroid function and calcium homeostasis after operations on the thyroid and parathyroid glands is a difficult assignment in endocrine surgery, and it is crucial to minimise the risks of permanent postoperative hypoparathyroidism. The aim of this thesis was to study the vascular supply of the parathyroid glands and the revascularisation, growth, and function of transplanted parathyroid tissue, in order to add new information about parathyroid preservation.

4. 3. Disturbance regimes in dry sandy grasslands – past, present and future

   Författare :Anja Ödman; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Grassland conservation; sand steppe; land use history; conceptual model; soil disturbance; lime; nutrient availability; vascular plants; bryophytes; ground beetles; propagule supply;

   Sammanfattning : A number of sandy grassland habitats of interest for biodiversity conservation can be found in Europe. One such habitat is the threatened xeric sand calcareous grassland, which is home to a large number of endangered species. LÄS MER

5. 4. Hypoxia in arterial and venous specification during vascular development

   Författare :Marcus Sohl; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : A developing embryo needs a constant supply of oxygen and nutrients in order to survive and grow into a functioning organism. During the earliest embryonic stages passive diffusion is enough to sustain the embryo. At later embryonic stages however, a system for delivering the necessary oxygen and nutrients to all parts of the embryo is needed. LÄS MER

7. 5. Altered expression of contractile endothelin receptors in the vascular bed

   Författare :Mikael Adner; Klinisk och experimentell allergiforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; upregulation; transcriptional regulation; smooth muscle cells; plasticity; organ culture; Endothelin; receptor; Kardiovaskulära systemet;

   Sammanfattning : This thesis aims at characterizing the endothelin (ET) receptors in different vascular beds of man and rat. The ET-A receptor was shown to be the only contractile ET receptor present in all vascular regions, with the exception of the rat mesenteric vein where a weak ET-B receptor-mediated contraction was seen.
