    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. Lysosomal Membrane Stability and Cathepsins in Cell Death

    Författare :Hanna Appelqvist; Karin Öllinger; Katarina Kågedal; Petra Wäster; Maria Shoshan; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Lysosomes are acidic organelles that are critically involved in a number of physiological processes, including macromolecule degradation, endocytosis, autophagy, exocytosis and cholesterol homeostasis. Several pathological conditions, such as cancer, neurodegenerative disorders and lysosomal storage diseases, involve lysosomal disturbances, indicating the importance of the organelle for correct cellular function.

  5. 4. The role of the mitochondrial membrane system in apoptosis : the influence of oxidative stress on membranes and their interactions with apoptosis-regulating Bcl-2 proteins

    Författare :Martin Lidman; Gerhard Gröbner; Magnus Wolf-Watz; Philip Williamson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bax; Bc-2; apoptosis; mitochondria; membranes; oxidized lipids; NMR; calorimetry; circular dichroism; biokemi; Biochemistry; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Apoptosis is a crucial process in multicellular organisms in sculpting them, especially during embryogenesis. In addition, apoptosis is responsible for the clearance of harmful or damaged cells which can otherwise be detrimental to the organism. LÄS MER

  7. 5. 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
