1. Calcium Homeostasis After Thyroid Surgery
Sammanfattning : Calcium homeostasis after thyroid surgery was studied during the immediate postoperative period and after one year. One day after hemithyroidectomy ionised calcium decreased whereas basal PTH did not change. EDTA stimulated maximal and total PTH secretion and set-point decreased on postoperative day 1 and normalised on day 7. LÄS MER
2. Bacterial cytochromes P450-Studies on Cytochrome P450 102A2 and P450 102A3 of Bacillus subtilis
Sammanfattning : Cytochromes P450 constitute a super-family of heme containing mixed function mono-oxygenases that is found in all branches of life. They introduce single oxygen atoms, mostly in the form of hydroxyl groups, into lipophilic substances and thereby render them more hydrophilic and susceptible to further reactions. LÄS MER
3. The N-terminal EGF Module of Coagulation factor IX. Studies of Calcium Binding and Module Interactions
Sammanfattning : Coagulation factor IX (FIX) is a vitamin K-dependent serine protease zymogen that circulates in plasma. Defects in FIX cause the bleeding disorder hemophilia B. FIX contains a Gla module, two Epidermal Growth Factor (EGF) -like modules and a serine protease region. LÄS MER
4. Alpha-1-microglobulin, heme-binding protein, reductase and antioxidant
Sammanfattning : This thesis describes structural and functional studies of alpha-1-microglobulin (a1m), a 26 kDa plasma and tissue protein that is evolutionarily well-conserved and belongs to the lipocalin superfamily. The lipocalins are polypeptides of 160-190-amino acids that are folded into an 8-stranded beta-barrel forming a pocket with a hydrophobic interior. LÄS MER
5. Early Rostrocaudal Patterning of the CNS
Sammanfattning : The transformation of an initially uniform population of epiblast cells into an intricately complex central nervous system (CNS) is one of the most fascinating processes during embryonic development. Presumptive neural cells are initially specified as cells of forebrain character. LÄS MER
