  2. 1. Motility of human polymorphonuclear leukocytes : An image processing approach

    Author : Mikael Gustafsson; Erik Gylfe; Linköpings universitet; []
    Keywords : Human polymorphonuclear leukocytes; locomotion; phagocytosis; Saccharomyces cerevisiae; membrane transport; intracellular free calcium; cellular pH; water influx; actin dynamics; digital video microscopy; image processing; fura-2; BCECF; DII; MEDICINE; MEDICIN;

    Abstract : Cell motility is essential for polymorphonuclear leukocyte (PMN) function in the defense against invading microorganisms and in inflammatory processes. Using digital video microscopy and image processing, individual cells were studied during random locomotion, chemotactic locomotion and phagocytosis. READ MORE

  4. 2. Mitochondrial function in sepsis - Temporal evolvement of respiratory capacity in human blood cells

    Author : Fredrik Sjövall; Lund Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human; sepsis; severe sepsis; septic shock; platelets; mitochondria; OXPHOS; high-resolution respirometry; mitochondrial disorders; multiple organ failure; biogenesis; leukocytes; cytokines; respirometry; oxygen consumption; blood cells; temporal;

    Abstract : Sepsis is a devastating disease that is caused by the host’s response to an overwhelming infectious process. As sepsis progresses, organs distant from the site of infection become affected and sepsis-induced multiple organ failure ensues. READ MORE

  5. 3. Human mononuclear phagocytes : Production of reactive oxygen species generated by the NADPH oxidase

    Author : Agneta Johansson; Roger Sundler; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Human professional phagocytes constitute the first line of defence against invading microorganisms. With a membrane-bound enzyme system, the NADPH oxidase, these cells generate bactericidal metabolites. Activation of NADPH oxidase results in a generation of reactive oxygen species, e.g. READ MORE

  7. 5. Chemotactic factors in the human follicle at ovulation

    Author : Eva Runesson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chemokine; follicle; gonadotropin; human; ovary; ovulation;

    Abstract : Ovulation is initiated by the midcycle gonadotropin surge, which leads to a controlled degradation of the follicle wall ending in follicular rupture and oocyte extrusion. The gonadotropins triggers several biochemical and biophysical changes such as vascular alterations, increased proteolytic enzyme activity and leukocyte extravasation, within the preovulatory follicle.
