  2. 1. Effects of imidazoline compounds on intracellular CA2+ and apoptosis

    Author : Ioulia Appelskog; Karolinska Institutet; Karolinska Institutet; []
    Keywords : imidazolines; imidazoline site; sulfonylurea; glucose; interleukin-1beta; insulin secretion; glucagon; somatostatin; pancreatic islets; pancreatic P-cells; HIT-T15 cells; apoptosis; cytoplasmic free Ca2 concentration;

    Abstract : Cytoplasmic free Ca2+ concentration ([Ca2+]i) plays a pivotal role in the regulation of insulin release from the pancreatic beta-cell. [Ca2+]i is also important in the control of apoptosis. READ MORE

  4. 2. The Synthesis and Use of Certain Pyridine Derivatives as Modulators of the G-protein Coupled Receptors mGlu5 and P2Y12

    Author : Peter Bach; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mGluR5; P2Y12; gastroesophageal reflux disease GERD ; thrombosis; ethyl nicotinates; ureas; sulfonylureas; oxazoles; bioisosteres; regioselectivity; solvent effect.;

    Abstract : The glutamatergic mGlu5 receptor and the purinergic P2Y12 receptor are two important targets in the development of novel treatments of gastroesophageal reflux disease (GERD) and thrombosis, respectively. Synthesis was developed to investigate the structure-activity relationships (SAR) of a novel series of 2-alkynylpyridine derivatives as mGluR5 antagonists. READ MORE

  5. 3. Metabolic signals and the ATP-sensitive potassium channel in the pancreatic beta-cell

    Author : Robert Bränström; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ATP-regulated K channel; pancreatic [beta]-cell oscillations; [alpha]-ketoisocaproate; long chain acyl-CoA esters; Kir6.2 SUR1 structure-function.;

    Abstract : ATP-sensitive K+ (KATP) channels are widely distributed in a variety of tissues and cell types. KATP channels are comprised of two subunits, a pore forming subunit (Kir6.x) and a regulatory sulfonylurea receptor (SURx). Both subunits are required for fully functional channels. READ MORE

  6. 4. Uptake and toxicity of brominated flame retardants and pesticides : Studies on littoral organisms and model communities

    Author : Kerstin Gustafsson; Nils Kautsky; Kirsten Christoffersen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aquatic ecotoxicology; ecological interactions; indirect effects; model community studies; toxicity; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : In this thesis, brackish and freshwater littoral model communities (microcosms) of varying size and complexity were used to study the effects of brominated flame retardants (BFRs) and pesticides. The brackish water microcosms consisted of natural water, sediment and associated organisms, while the larger freshwater microcosms also contained submersed macrophytes (Elodea canadensis). READ MORE
