1. 16. Calcium Homeostasis After Thyroid Surgery

   Författare :Pia Lindblom; Lund Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PTH-peripheral effects; hPTH- 1-34 infusion; EDTA infusion; Set-point; Vitamin D3; PTH; Calcium; Thyroid surgery; Postoperative hypocalcemia; Bone density.; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Reduced thyroid hormones;

   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

3. 17. Chloride Homeostasis in Central Neurons

   Författare :Tushar Yelhekar; Staffan Johansson; Michael Druzin; Merab Kokaia; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chloride concentration; current-voltage relation; interpolation; voltage ramp; reversal potential; [Cl–]i recovery; KCC2; extracellular matrix; GABAA receptor; chloride leak conductance; neurosteroid; fysiologi; Physiology;

   Sammanfattning : The overall aim of the present thesis is to clarify the control of intracellular chloride homeostasis in central neurons, because of the critical role of chloride ions (Cl–) for neuronal function. Normal function of the central nervous system (CNS) depends on a delicate balance between neuronal excitation and inhibition. LÄS MER

4. 18. Isoform-specific regulation of Drosophila gut immunity and regeneration by the POU/Oct transcription factor Nub/Pdm1

   Författare :Xiongzhuo Tang; Ylva Engström; Tony Ip; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; POU; Nubbin; Drosophila; intestinal stem cell; epithelium regeneration; midgut; mitosis; Antimicrobial peptides; innate immunity; NF-κB; bacterial infection; transcriptional regulation; homeostasis; Molecular Biology; molekylärbiologi;

   Sammanfattning : Innate immune reactions protect organisms against a variety of infections.  In metazoans, these reactions involve both cellular and humoral responses. The immune responses have to be well-tuned, as excessive immune activation is associated with tissue-specific pathologies. LÄS MER

5. 19. The brain-pituitary-gonadal axis of the three-spined stickleback, Gasterosteus aculeatus

   Författare :Yi Ta Shao; Bertil Borg; Sylvie Dufou; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; BPG axis; GnRH; lh-β; fsh-β; three-spined stickleback; Gasterosteus aculeatus; homeostasis; feedback; funktionell zoomorfologi; Functional Zoomorphology;

   Sammanfattning : The seasonal reproduction of the three-spined stickleback is stimulated by long day photoperiod. As in other vertebrates, the reproductive system of stickleback is regulated by the brain-pituitary-gonadal (BPG) axis which is largely controlled by feedback effects. Both negative and positive feedback effects on the BPG axis have been found in fish. LÄS MER

7. 20. The gamma-tubulin meshwork as a therapeutic target

   Författare :Lisa Lindström; Malmö Molekylär patologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gamma-tubulin; retinoblastoma; nuclear formation; meshwork; mitochondria; homeostasis;

   Sammanfattning : Cancer is a heterogeneous disease and treatment regime is dependent on type and location of the tumor. Several of the commonly used chemotherapeutics target the functions of the microtubules. One of the major problems with these drugs is the adverse effects associated with their use. LÄS MER
