  1. 1. Pulsed Electric Field Treatment of Plant Tissue

    Författare :Mustafa Fincan; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bimodal Fickian diffusion model; Food and drink technology; Livsmedelsteknik; generalized Maxwell model; onion Neutral Red; visualization; red beetroot; potato; epidermis; plant tissue; electroporation; Cell permeabilization; Pulsed electric field; PEF;

    Sammanfattning : A pulsed electric field (PEF) is a newly emerged non-thermal food processing technology which has characteristic effects on the cell membrane. PEF processing involves subjecting food to short, repeated pulses of a high electric field between an anode and a cathode. LÄS MER

  3. 2. Inactivation, Cell Injury and Growth of Microorganisms Exposed to Pulsed Electric Fields Using a Continuous Process

    Författare :Kristina Aronsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Leuconostoc mesenteroides; PEF; Listeria innocua; cell injury; flow-through treatment chamber; membrane permeabilization; post-processing growth; microbial inactivation; pulsed electric fields; Escherichia coli; Saccharomyces cerevisiae;

    Sammanfattning : Pulsed electric fields (PEF) is a proven technology to inactivate microorganisms under non-thermal conditions. The PEF technology has a potential as a "quality friendly" alternative to traditional methods of food preservation. LÄS MER

  4. 3. Cat and dog allergens : dispersal, exposure and health effects in childhood

    Författare :Catarina Malmros; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Child; asthma; allergy and immunology; cats; dogs; allergens; IgE; schools; clothing; PEF; heredity; prospective studies; confounding factors; primary prevention; environment and public health;

    Sammanfattning : The association between pet ownership in childhood and subsequent asthma and sensitisation is very controversial. Intriguing but contradictory reports have caused considerable uncertainty in families who wish to avoid asthma and allergic disease in their children. LÄS MER

  5. 4. Impregnation of Leaf Tissues and its Consequences on Metabolism and Freezing; Study on Vacuum Impregnation and Pulsed Electric Field Treatment

    Författare :Katarzyna Dymek; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Freezing is a widely used method of preserving food products. Efforts are currently being directed towards improving the quality of the sensitive tissues of plant foods such as leaves, after freezing and thawing. LÄS MER

  7. 5. Effects of ionising and non-ionising radiation in cell systems and a rat model for immuno-therapy

    Författare :Catrin Baureus Koch; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kirurgi; ortopedi; traumatologi; Neurology; traumatology; transplantation; Surgery; orthopaedics; cell cultures; abscopal effect; serologi; Immunologi; serology; Immunology; rat tumour model; radiation therapy; radiation sterilisation; pulsed electric fields; interferon-gamma; immuno-gene therapy; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; glioblastoma multiforme;

    Sammanfattning : The most malignant brain tumour, glioblastoma multiforme (GBM), has an utterly bad prognosis. In spite of all available therapy, the mean survival time is less than a year. In the unique BRIGTT project (Brain Immuno Gene Tumour Therapy), patients at the Dept of Neurosurgery. LÄS MER
