  4. 3. Signal transduction in the brain : modulation of receptor-mediated inositol phospholipid breakdown by potassium and fluoride ions

    Författare :Gunnar Tiger; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Inositol phospholipid breakdown; muscarinic receptors; potassium; fluoride; rat brain; pig brain;

    Sammanfattning : Neurotransmitter receptor types mediating the generation of intracellular signals are of two types; ligand-gated ion channels and G protein coupled receptors. The effector enzyme phosphoinositide-specific phospholipase C (PLC) is modulated by stimulation of G protein coupled receptors, leading to an increased breakdown of inositol phospholipids ("Ptdlns breakdown").

  5. 4. Submicron Calcium Phosphate Spheres for Biomedical Applications : Synthesis and Use

    Författare :Tao Qin; Håkan Engqvist; Fredrik Nikolajeff; Jie Huang; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium phosphate; spheres; dentinal hypersensitivity; drug release; tooth bleaching;

    Sammanfattning : Calcium phosphate spheres as biomaterials have been attracting attention in recent years. Calcium phosphate occurs naturally in bone, and a hollow structure could be advantageous for drug loading and release. LÄS MER

  7. 5. Case Studies in Ion Beam Assisted Nanostructure Engineering

    Författare :Rajdeep Kaur; Petter Ström; Daniel Primetzhofer; Tuan Tran; Naureen Ghafoor; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ion irradiation; material modification; nanostructures; calcium fluoride; polyimide; etching; Fysik; Physics;

    Sammanfattning : Beams of energetic ions can be used for material analysis and modification. It provides us with a tool featuring unique control over the area, depth and amount of damage in the material. This property of ion beams can be used to generate desired changes in material properties or form nanostructures with specific characteristics in the material. LÄS MER
