  2. 1. In vitro accessibility of provitamin A carotenoids in vegetables and fruits - Effects of different process and preparation methods and estimation of vitamin A activity

    Author : Ellen Hedrén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in vitro accessibility; provitamin A carotenoids; lactic acid fermentation; food matrix; cell wall degrading enzymes; vegetables; vitamin A activity; beta-carotene; red palm oil; fruits;

    Abstract : Vitamin A deficiency is a major nutritional problem in many developing countries, caused chiefly by a diet with low retinol content. The bioefficacy of provitamin A carotenoids in plant foods is claimed to be insufficient to maintain a satisfactory vitamin A status. READ MORE

  4. 2. Assessment of microvascular effects of vasoactive drugs : Methodological in vivo studies in humansbased on iontophoresis

    Author : Joakim Henricson; Folke Sjöberg; Gert Nilsson; Erik Droog Tesselaar; Jonas Åkeson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Cardiovascular disease is the leading cause of death in western societies and endothelial dysfunction is one of the earliest signs seen in the development of such conditions. Thedevelopment of prognostic tools to aid in the prediction of micro- and macrovascular diseasebased on assessment of vascular reactivity is therefore of paramount importance. READ MORE

  5. 3. Protein synthesis in vitro in skeletal muscle as an indicator of feeding conditions

    Author : Bernt Lund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The activity of protein synthesis in vitro was determined using ribosomes isolated from rats, domestic animals and fish. The activity of rat skeletal muscle ribosomes was influenced by small differences in the nutritional quality of dietary proteins. READ MORE

  6. 4. Small-Scale Dosimetry for the Testis: Applications in Nuclear Medicine Diagnostics and Therapy

    Author : Suaad Meerkhan; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Testis; 111-In; Autoradiography; Biodistribution; Small-Scale; Monte Carlo; Dosimetry; spermatogonia; gammaH2AX; immunofluorescence;

    Abstract : It is well known that the testicles are among the most radiosensitive tissue, and constitute an important critical target for both external and internal radiation during diagnostic and therapeutic use of radionuclides. In systemic radionuclide therapy where very high activities are administered, the testis may become a dose-limiting organ; often with a complex, non-uniform activity distribution and a resulting non-uniform absorbed-dose distribution.

  7. 5. Characterisation and modelling of radio-frequency lesioning in functional neurosurgery

    Author : Ola Eriksson; Karin Wårdell; John Koivukangas; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : This thesis focuses on the characterisation and modelling of the radio frequency (RF) lesioning with emphasis on size estimation in functional neurosurgery. A computer-assisted video system has been set up for standardised test and documentation of protein clots generated by RF-lesioning electrodes in an albumin solution. READ MORE
