  2. 1. Phosphoinositides control insulin secretion through multiple routes

    Author : Phuoc My Nguyen; Christina Bark; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phosphoinositides; PI 4 P; PI 4; 5 P2; Ca2 ; optogenetics; VDCC; Sac2; OSBP; OSW-1; cholesterol; membrane contact sites;

    Abstract : Glucose-stimulated insulin secretion from pancreatic beta cells is the sequence of events that starts with glucose uptake and ends with the fusion of insulin granules with the plasma membrane through Ca2+-triggered exocytosis. Phosphoinositides are minor components of all cellular membranes, yet play fundamental roles as regulators of many cellular processes. READ MORE

  4. 2. Mesoporous magnesium carbonate : Synthesis, characterization and biocompatibility

    Author : Sara Frykstrand Ångström; Maria Strømme; Johan Gómez de la Torre; Natalia Ferraz; Mika Lindén; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mesoporous; magnesium carbonate; pore size control; cytotoxicity; in vivo; skin irritation; acute systemic toxicity; hemocompatibility; Ca2 uptake; solubility enhancement; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Abstract : Mesoporous materials constitute a promising class of nanomaterials for a number of applications due to their tunable pore structure. The synthesis of most mesoporous materials involves a surfactant liquid crystal structure to form the pores. READ MORE

  5. 3. Ca2+ fluxes and insulin action in cardiac and skeletal muscles

    Author : Johanna T Lanner; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Obesity and type 2 diabetes are major and rapidly increasing health problems in society. They are associated with several life-threatening conditions, including heart and renal failure, and damage to the nervous system. An inability of cells to respond normally to insulin, insulin resistance, is a key feature in obesity and type 2 diabetes. READ MORE

  6. 4. Calcium transport in the Pacific oyster, Crassostrea gigas - in a changing environment

    Author : Kirsikka Sillanpää; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate changes; Ussing chambers; Calcium uptake; Sodium potassium ATPase; Calcium ATPase; Sodium calcium exchanger; Calcium channel; Hemocytes; Mantle epithelium;

    Abstract : Pacific oyster, Crassostrea gigas, is globally one of the most important farmed bivalve species. A prominent features of the C. gigas is the thick CaCO3 shell covering the body of the animal and protecting it from the environment. READ MORE

  7. 5. Asexual embryogenesis in plants

    Author : Boel Mårtensson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systematic botany; two-phase partitioning; somatic embryogenesis; pollen embryogenesis; plasma membrane; peroxidase; Daucus carota isoperoxidase; Nicotiana tabacum; Ca2 transport; cell shape; calmodulin; taxonomy; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

    Abstract : The capacity of somatic cells and pollen grains or microspores to undergo embryogenesis is an important property used in improvement and regeneration of plants. Furthermore, somatic embryogenesis as well as pollen embryogenesis show many similarities with zygotic embryogenesis and are, thus, good model systems. READ MORE
