    Sammanfattning : Silicon nanowires (SiNW) are in the spotlight for a few years in the research community as a good candidate for biosensing applications. This is attributed to their small dimensions in nanometer scale that offers high sensitivity, label-free detection and at the same time utilizing small amount of sample. LÄS MER

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell separation; cortical magnification; detection; estimated receptive field; high-pass filtered optotypes; nyquist limit; psychophysics; resolution; ganglion cells;

    Sammanfattning : Aims: The aim of this thesis was to formulate a model of retinal neural circuitry in humans based on morphological estimates of retinal cone and ganglion cell populations, to compare results based on this model to psychophysical measurements of visual resolution and identify the retinal neural factors that limit visual resolution.Materials & Methods: Total displacement of central ganglion cells from foveal cones was obtained by estimating the length of fibers of Henle in four human retinas along the nasal or vertical hemi-meridians.

  7. 5. Sensitivity, Noise and Detection of Enzyme Inhibition in Progress Curves

    Författare :Omar Gutierrez Arenas; Helena Danielson; Athel Cornish-Bowden; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Progress curves; limit of detection; Z -factor; primary screening; enzyme inhibition; error structure; sensitivity analysis; High-throughput screning; Biokemi;

    Sammanfattning : Starting with the development of an enzymatic assay, where an enzyme in solution hydrolysed a solid-phase bound peptide, a model for the kinetics of enzyme action was introduced. This model allowed the estimation of kinetic parameters and enzyme activity for a system that has the peculiarity of not being saturable with the substrate, but with the enzyme. LÄS MER
