  1. 1. Development of a New Biomechanical ex vivo Perfusion System - Studies on effects of biomechanical and inflammatory stress on hemostatic genes in human vascular endothelium

    Author : Niklas Bergh; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ex vivo perfusion system; biomechanical; endothelium; shear stress; tensile stress; pulsatile; TNF-α; JNK; hemostatic genes;

    Abstract : The vascular endothelium is a multifunctional interface constantly exposed to biomechanical forces such as shear and tensile stress. Biomechanical stress is involved in the pathophysiological process of the vessel wall and thus affects vascular remodeling, atherosclerosis and thrombogenesis. READ MORE

  2. 2. Methods, Instrumentation and Mechanisms for Optical Characterization of Tissue and Treatment of Malignant Tumours

    University dissertation from Department of Physics, Lund University

    Author : Sara Pålsson; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; temperature; perfusion; PDT; photodynamic therapy; mechanisms; tissue characterization; instrumentation; optical biopsy; fluorescence spectroscopy; spectroscopy techniques; Raman spectroscopy; interstitial photodynamic therapy; photodynamic threshold dose; Atomic and molecular physics; Atom- och molekylärfysik;

    Abstract : In this thesis, different optical methods utilising visible light for characterization of tissue have been developed and evaluated. The feasibility of many of these methods has been demonstrated in the laboratory or in animal experiments. READ MORE

  3. 3. Multiparametric MRI for evaluation of tumour treatment response Studies of 177Lu-octreotate therapy of neuroendocrine tumour

    University dissertation from Department of Physics, Lund University

    Author : Mikael Montelius; Göteborgs universitet.; Gothenburg University.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; Functional imaging; IVIM; MRI; DWI; DCE; histology; 177Lu-octreotate; small intestine neuroendocrine tumour; NET; diffusion; perfusion; semi-quantitative; proteomics; ionizing radiation; biology; imaging biomarker;

    Abstract : Clinical assessment of tumour response to treatment largely relies on estimates of tumour size by, e.g., measuring the largest tumour diameters on magnetic resonance (MR) or computed tomography (CT) images, weeks or months after treatment. READ MORE

  4. 4. Lung Transplantation: Clinical and experimental studies

    University dissertation from Department of Respiratory Medicine and Allergology, Lund University

    Author : Leif Eriksson; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Respiratory system; Follow up Studies; Vascular Resistance; Intensive Care; Induced; Hypothermia; Swine; Extracorporeal Circulation; Lung Transplantation; Organ Preservation; Andningsorganen; Immunology; serology; transplantation; Immunologi; serologi;

    Abstract : During the past 15 years lung transplantation has been established as a therapeutic option for patients with end-stage pulmonary disease. The results have improved over time and some transplantation centers now show 1-year survival rates above 80%. READ MORE

  5. 5. Proton Relaxation Properties of a Particulate Iron Oxide MR Contrast Agent in Different Tissue Systems Implications for Imaging

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Atle Bjørnerud; Uppsala universitet.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Iron oxide nanoparticles; USPIO; NC100150 Injection; water exchange limited relaxation; MR perfusion imaging.; Onkologi; MEDICINE Surgery Oncology; MEDICIN Kirurgi Onkologi; radiologi; Radiology;

    Abstract : Knowledge of the relationship between in vivo contrast agent concentration and magnetic resonance (MR) signal response is an important requirement in contrast enhanced MR imaging in general and in MR based perfusion imaging in particular. This relationship is a complex function of the properties of the contrast agent as well as the structure of the target tissue. READ MORE
