  2. 6. Dysfunctional but viable myocardium - ischemic heart disease assessed by magnetic resonance imaging and single photon emission computed tomography

    Author : Martin Ugander; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; medical instrumentation; Klinisk fysiologi; radiology; tomography; Clinical physics; non-invasive imaging; myocardial infarction; viability; Physiology; Fysiologi; Cardiovascular system; Kardiovaskulära systemet;

    Abstract : The assessment of ischemic heart disease (IHD) often focuses on the detection of dysfunctional but viable myocardium which may improve in function following revascularization. Dysfunctional but viable myocardium is identified by distinct characteristics with regards to function, perfusion and viability. READ MORE

  4. 7. Maintenance and Commitment of Hematopoietic Progenitors: Role of flt3, c-kit and c-mpl

    Author : Ole Johan Borge; Avdelningen för molekylärmedicin och genterapi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; KL; hematopoiesis; FL; cytokines; B-cells; commitment; flt3; differentiation; Haematology; IL-7; c-kit; progenitors; Hematologi; stem cells; thrombopoietin; viability; extracellular fluids; extracellulära vätskor;

    Abstract : The need for red blood cells to transport oxygen and CO2, blood platelets to stop bleedings, and neutrophils, macrophages, B- and T-cells for host defense, is a prerequisite for life. These mature blood cells have a limited life span and are thus constantly replenished by an enormous cell production (estimated to 1012 cells per day) which primarily takes place in the bone marrow (BM).

  5. 8. On cobalt-chrome frameworks in implant dentistry

    Author : Lars Hjalmarsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cobalt-chrome; titanium; implants; misfit; corrosion; viability; abutment-free;

    Abstract : Background: Cobalt-chrome (CoCr) alloys have been used in dentistry in decades but very little is known about their behavior and biological impact as framework materials in implant dentistry. Furthermore, few studies have evaluated and compared the clinical and radiological results of abutment and abutment-free implant treatment concepts. READ MORE

  6. 9. Analytical tools for monitoring and control of fermentation processes

    Author : Heléne Sundström; Sven-Olof Enfors; Carl-Fredrik Mandenius; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Escherichia coli; flow cytometry; software sensors; viability; inclusion bodies; biomass; specific growth rate; stress; population heterogeneity; process analytical technology.; Biochemical process engineering; Biokemisk och bioteknisk processteknik;

    Abstract : The overall objective of this work has been to adopt new developments and techniques in the area of measurement, modelling and control of fermentation processes. Flow cytometry and software sensors are techniques which were considered ready for application and the focus was set on developing tools for research aiming at understanding the relationship between measured variables and process quality parameters.

  7. 10. Olfactory Transfer of Analgesic Drugs After Nasal Administration

    Author : Ulrika Espefält Westin; Erik Björk; Eva Brittebo; Margareta Hammarlund-Udenaes; Paolo Colombo; Uppsala universitet; []
    Keywords : Pharmaceutics; Nasal administration; Olfactory transfer; Olfactory pathways; Central nervous system; Blood-brain barrier; Nasal respiratory mucosa; Olfactory mucosa; Olfactory bulb; Horizontal Ussing chamber; Morphine; Dihydroergotamine; Rat; Mouse; Swine; Autoradiography; Viability; Powder formulations; Galenisk farmaci;

    Abstract : Nasal administration of analgesics for achieving rapid pain relief is currently a topic of great interest. The blood-brain barrier (BBB) restricts access to the central nervous system (CNS) for several central-acting drugs, such as morphine and dihydroergotamine, which results in a substantial effect delay.
