1. 1. Growth regulation in sarcomas : studies in vivo and in cell culture

   Författare :Avni Abdiu; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Sarcomas are malignant tumors of mesenchymal origin, and can arise in soft-tissue and in bones. It has been suggested that the abnormal growth regulation in sarcoma cells may be due to an autocrine mechanism, in which the cells are stimulated by an endogenous production of growth factors.

3. 2. Regulation of Renal Hyaluronan in Water Handling : Studies in vivo and in vitro

   Författare :Sara Stridh; Peter Hansell; Mats Rundgren; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney; water balance; fluid handling; diabetes; nephropathy; ACE fetopathy; reabsorption; hyaluronic acid; glycosaminoglycan; GAG; extracellular matrix; mTOR; rapamycin; streptozotocin;

   Sammanfattning : Hyaluronan (HA) is a negatively charged extracellular matrix (ECM) component with water-attracting properties. It is the dominating ECM component in the renal medullary interstitium, where the amount changes in relation to hydration status: it increases during hydration and decreases during dehydration.

4. 3. Up-regulation of dopamine D₂ receptors : in vitro and in vivo studies

   Författare :Maria Wanderoy; Eliassitet Eriksson; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurochemistry; Neurokemi; neurokemi och neurotoxikologi; Neurochemistry and Neurotoxicology;

   Sammanfattning : In the central nervous system (CNS) dopaminergic and dopaminoceptive neurons have the ability to respond to variations in dopamine levels by for example adjusting their dopamine receptor levels. One of the most well known phenomena in this respect is that long-term blockade of D2 receptors with antipsychotic drugs leads to an increase in striatal D2 receptor density of experimental animals as well as of schizophrenic patients as measured in both post-mortem studies and in vivo positron emission tomography studies of brain.

5. 4. The Role of Microvascular Pericytes in the Generation of Pro-fibrotic Connective Tissue Cells : Investigations in vitro and in Reactive Tissues in vivo

   Författare :Jakob Karén; Christian Sundberg; Gunilla Westergren-Thorsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pericyte fibroblast differentiation fibrosis; Biochemistry; Biokemi; Microbiology; Mikrobiologi; Cell biology; Cellbiologi; Medical Biochemistry; Medicinsk biokemi; Cellforskning; Cell Research; Mikrobiologi; Microbiology;

   Sammanfattning : Pericytes are cells of mesenchymal origin located on the abluminal side, juxtapositioned to the endothelial cells in capillaries, venules and small arterioles. They are important for maintaining vessel integrity in resting tissues as well as the formation and stabilization of new vessels. LÄS MER

7. 5. Regulation of Ovarian Aromatase: Studies by Aromatase Assays in vitro and in vivo

   Författare :Dmitrijus Kirilovas; Mats Brännström; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; aromatase; human; granulosa cells; 11C-vorozole; active site; allosteric configuration; in vitro; in vivo; PET; androgens; rat; estrous cycle.; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; Obstetrics and Gynaecology; obstetrik och gynekologi;

   Sammanfattning : An in vitro method was developed for measuring aromatase, based on binding of competitive aromatase inhibitor [11C]vorozole to the active site of the enzyme. [11C]Vorozole displayed high, specific binding in vitro to human placenta and human granulosa cells (GC), both fresh and frozen/thawed cells, provided correct procedures were used. LÄS MER
