  1. 21. Scanning probe microscopy studies of interaction forces between particles: emphasis on magnetite, bentonite and silica

    Författare :Illia Dobryden; Neil Thomson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Sammanfattning : Scanning probe microscopy (SPM), such as the atomic force microscope (AFM), using colloidal probes is a highly suitable technique to probe single particle-particle interactions in aqueous solution. The interaction force between a colloidal probe on the AFM cantilever and sample surface is measured. LÄS MER

  3. 22. Physiological aspects on intracardiac blood flow

    Författare :Per Arvidsson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; 4D flow; physiology; cardiac development; kinetic energy; hemodynamic force; vortex ring formation;

    Sammanfattning : Magnetic resonance imaging enables detailed in vivo study of complex flow through 3D, time-resolved phase contrast imaging (4D flow). 4D flow may reveal previously unknown aspects of the physiology of intracardiac blood flow, and possibly elucidate pathophysiological processes that have yet to manifest themselves outside the heart.

  4. 23. Development and applications of NMR relaxation methods to study protein and ligand dynamics

    Författare :Sven Wernersson; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear magnetic resonance; NMR; NMR relaxation; Method development; Protein dynamics; BRD4; Galectin 3; Kärnmagnetisk resonansspektroskopi; proteindynamik; Metodutveckling; NMR; BRD4; Galektin 3;

    Sammanfattning : This thesis involves the study of proteins. These molecules exist in many variants, and perform most of our bodily functions. This includes signaling (for example the presence of capsaicin, which makes food spicy), molecular transport (including oxygen), catalysis (including food digestion) and part of our body structure (such as muscles).

  5. 24. Clinical Consequences of Axonal Injury in Traumatic Brain Injury

    Författare :Sami Abu Hamdeh; Niklas Marklund; Per Enblad; Lars Hillered; Andreas PhD Unterberg MD; Uppsala universitet; []
    Nyckelord :Traumatic brain injury; diffuse axonal injury; intracranial pressure; magnetic resonance imaging; amyloid-beta; tau; Neurokirurgi; Neurosurgery;

    Sammanfattning : Traumatic brain injury (TBI), mainly caused by road-traffic accidents and falls, is a leading cause of mortality. Survivors often display debilitating motor, sensory and cognitive symptoms, leading to reduced quality of life and a profound economic burden to society. LÄS MER

  7. 25. New Bioanalytical Approaches, Magneto Immunoassays and SIRE Technology Based Biosensors

    Författare :Kirstin Kriz; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemical technology; Biokemisk teknik; antigens; superparamagnetic nanoparticles; magnetic inductance transducer; competitive magneto immunoassay; enzymes; metabolites; differential measurements; SIRE; biosensor;

    Sammanfattning : This thesis presents two new technologies, SIRE technology based biosensors and magneto immunoassays, which can be used for bioanalytical applications. One of the main problems associated with biosensor technology is the instability of the recognition element since it is of biological origin and thus, has a limited lifetime. LÄS MER
