  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

    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 : Popular Abstract in Swedish Denna avhandling handlar om hur ljus kan användas för att detektera, diagnosticera och behandla olika medicinska sjukdomstillstånd. Det vi dagligen kallar ljus är bara en liten del av det elektromagenetiska spektret, nämligen den del vi kan uppfatta med våra ögon. 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; Lunds universitet.; Lund University.; [1998]

    Abstract : Popular Abstract in Swedish Transplantation av lungor är ett relativt nytt behandlingsalternativ vid svår lung-sjukdom. Den första lungtransplantationen på människa gjordes 1963. Patienten dog efter 18 dagar i njursvikt. Mellan 1963 och 1980 gjordes ca 40 lungtransplantationer i världen med nedslående resultat. 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
