  2. 21. Development of Ultra-fast Biosensors for Detection of Non-electroactive Neurotransmitters

    Author : Yuanmo Wang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; artificial cell; quantification; stability; deformation; dynamic light scattering; adsorption; amperometry; nanoparticle tracking analysis; enzyme monolayer; glucose oxidase; exocytosis; choline oxidase; acetylcholine; enzymatic activity; acetylcholine esterase; gold nanoparticles; Biosensor;

    Abstract : During neuronal communication neurotransmitters are released through the process exocytosis that occurs on the time scale of sub-milliseconds to milliseconds. Neuronal activity by neurotransmitters that are non-electroactive cannot easily be monitored due to limitations in the temporal resolutions of the sensor probes for these analytes. READ MORE

  4. 22. Protein kinases in hormonal regulation of adipocyte metabolism

    Author : Christine Berggreen; Proteinfosforylering; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adipocyte; PKB; AMPK; SIK3; insulin; catecholamines; lipolysis; lipogenesis; glucose uptake; de novo fatty acid synthesis; A769662; Akti; cAMP;

    Abstract : Abstract Along with liver and muscle tissue, adipose tissue helps maintain normal levels of glucose and lipids in the blood and has a very important role when it comes to storing lipids that can provide whole-body energy. After a meal is ingested, adipocytes take up glucose from the circulation and use it as a substrate for synthesis of new fatty acids (FAs) in a process known as de novo fatty acid synthesis, as well as for synthesis of glycerol.

  5. 23. Clinical aspects on glucose-lowering therapies in type 2 diabetes

    Author : Åsa Nybäck-Nakell; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Type 2 diabetes is a progressive disease with deterioration of glycaemic control over time in association with loss of endogenous insulin secretion. As a consequence of this, sulphonylureas (SU), which exert their mode of action by stimulating the pancreatic β-cells, are expected to be less effective with longer duration of diabetes. READ MORE

  6. 24. Flow injection systems for process analytical chemistry

    Author : Ingrid Lukkari; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Flow injection; Sequential injection; Process analytical chemistry; Multivariate calibration; Sensor injection; Gas-diffusion; Sample clean-up;

    Abstract : Flow injection systems have great potential for sample handling and analysis in process analytical chemistry. The flexibility and versatility of flow injection manifolds can he utilized in specific applications of sample conditioning and analysis. READ MORE

  7. 25. Fabrication and characterization of ZnO nanostructures for sensing and photonic device applications

    Author : Syed M. Usman Ali; Magnus Willander; Omer Nour; Frank Bier; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanotechnology; zinc oxide; nanowires nanorods; nanotubes; nanoporous nanoflakes; electrochemical sensor and photonic devices;

    Abstract : Nanotechnology is an emerging inter-disciplinary paradigm which encompasses diverse fields of science and engineering converge at the nanoscale. This nanoscale science and nanostructure engineering have well demonstrated in the fabrication of sensors/transducers devices with faster response time and better sensitivity then the planer version of the sensor’s configurations.
