  1. 6. Non-invasive ultrasound-based cardiovascular imaging in mouse models of atherosclerosis

    Författare :Julia Grönros; Göteborgs universitet; []
    Nyckelord :atherosclerosis; ultrasound-based imaging; cardiovascular disease; coronary artery; mouse; color Doppler echocardiography; ultrasound biomicroscopy; statin;

    Sammanfattning : Atherosclerosis is a chronic multi-factorial vascular disease. It generally requires large clinical settings and over many years to study the disease progression in man. Genetically modified mouse models of atherosclerosis have dramatically increased research feasibility within this area. LÄS MER

  3. 7. Artery Wall Imaging and Effects of Postmenopausal Estrogen Therapy

    Författare :Kenny A. Rodriguez-Macias Wallberg; Tord Naessén; Lars-Åke Mattsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; artery wall thickness; tunica media; tunica intima; arterial stiffness; carotid; aorta; cardiovascular disease; atherosclerosis; menopause; estrogen; hormone therapy; ultrasound; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Sammanfattning : Postmenopausal estrogen therapy, initiated early in the menopause, seems to protect against development of atherosclerosis and cardiovascular diseases. This thesis concerns studies of artery wall thickness and arterial stiffness estimated by noninvasive ultrasound techniques in long-term estrogen treated postmenopausal women who initiated therapy at the time of the menopause.

  4. 8. Longitudinal Common Carotid Artery Wall Motion - mechanistic, prognostic and translational studies

    Författare :Sara Svedlund; Göteborgs universitet; []
    Nyckelord :carotid artery; longitudinal wall motion; ultrasound; velocity vector imaging; risk factor;

    Sammanfattning : The longitudinal arterial movement of the common carotid artery (CCA) has been less investigated during the past compared to the radial movement. This is probably due to lack of an adequate measuring method. Velocity vector ultrasound imaging (VVI) now enables assessment of the longitudinal movement. LÄS MER

  5. 9. Disruption of moth mating behaviour by olfactory and auditory cues

    Författare :Glenn Svensson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; ultrasound; predation risk; selection; heritability; flight tunnel; harmonic radar; pest control; mating disruption; pheromone communication; Pyralidae; Lepidoptera; Noctuidae; Animal ecology;

    Sammanfattning : The impact of olfactory and auditory cues on the mating behaviour in two species of moths, Agrotis segetum (Noctuidae) and Plodia interpunctella (Pyralidae), was investigated to evaluate their potential use in integrated pest management. The flight behaviour of male A. LÄS MER

  7. 10. Structural health monitoring of large concrete structures

    Författare :Patrik Fröjd; Teknisk geologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diffuse wave fields; coda waves; structural health monitoring; ultrasound; continuous wave;

    Sammanfattning : There is an increasing demand on the safety and reliability of the civil structures that make up our cities and infrastructure. The field of structural health monitoring aims to provide continuous non-destructive evaluation of such structures. LÄS MER
