Meijer, P. (author), Westerveld, W. (author), Huisman, L.G.M. (author), Gaubius Laboratory TNO Preventie en Gezondheid (author)Comparison of the results for α2-antiplasmin activity of plasma samples (n = 61, range 0-125%) obtained by the 'immediate plasmin inhibition test' (IPIT) and by the automated method for the MLA Electra 1000C of Dade® shows a good correlation (R = 0.935) but a systematic disagreement especially relevant in the range below 40%. An improved method...article 1994

Kooistra, T. (author), Schrauwen, Y. (author), Arts, J. (author), Emeis, J.J. (author), Gaubius Instituut TNO (author)The fibrinolytic activity of blood is to a large extent determined by the plasma level of tissue-type plasminogen activator (t-PA). Changes in the plasma level of t-PA are mainly achieved by the endothelium by two mechanisms: (a) a rapid, short-term release of t-PA, which occurs within minutes (acute release, regulated secretion) and (b) a long...article 1994

van Hinsbergh, V.W.M. (author), Vermeer, M. (author), Koolwijk, P. (author), Grimbergen, J. (author), Kooistra, T. (author), Gaubius Laboratory TNO Preventie en Gezondheid (author)The plasminogen activator inhibitor PAI-1 is markedly elevated in vivo and in vitro upon exposure to the inflammatory mediators tumor necrosis factor α (TNFα), interleukin-1 (IL-1), and bacterial lipopolysaccharide. Here we report that the isoflavone compound genistein prevents the increase in synthesis of PAI-1 induced by these inflammatory...article 1994

Bos, R. (author), Revet, M. (author), Nieuwenhuizen, W. (author), Gaubius Laboratory TNO Preventie en Gezondheid (author)This article describes a two-step bio-immuno assay (BIA), which determines active (free) tissue-type plasminogen activator (t-PA) in (acidified) plasma. Plasma samples, diluted in buffer of pH 6.0, are added to the wells of a microtiter plate containing an immobilised monoclonal antibody which binds t-PA without affecting t-PA activity. After an...article 1994

Kluft, C. (author), TNO Preventie en Gezondheid (author)In the population at large and in individual normal volunteers, baseline molar concentratios of t-PA and PAI-1 in plasma show a strong correlation. Evidence is summarized that insulin resistance is a prominent cause of interindividual variation, next to possible contributions of vascular inflammation and steroid hormones. In healthy volunteers,...article 1994

(author), Gaubius Laboratory TNO Preventie en Gezondheid Instituut voor verouderings- en vaatziekten onderzoek TNO (author)Fibrinolytic parameters and von Willebrand factor (vWF) antigen were measured in the plasma of 10 patients with hemolytic uremic syndrome (HUS). Samples were taken at presentation and again 2 wk later, before and after infusion of 1-desamino-8-arginine vasopressin. Compared with the plasma values of healthy control children, levels of tissue...article 1994

Padró, T. (author), van den Hoogen, C.M. (author), Emeis, J.J. (author), Instituut voor verouderings- en vaatziekten onderzoek TNO (author)The aim of the present study was to investigate whether hypothyroidism would affect the components of the rat plasma fibrinolytic system. Hypothyroidism was induced by feeding rats a thiouracil-containing diet for 2 weeks. During this period, half of the animals received subcutaneous injections of L-thyroxine (20 μg/kg daily) to restore thyroid...article 1993

Nieuwenhuizen, W. (author), Gaubius Laboratory Instituut voor verouderings- en vaatziekten onderzoek TNO (author)Increased plasma levels of soluble fibrin are considered as molecular markers of an impending thrombotic event. Several methods to assess soluble fibrin have been in existence for many years. Most of those methods are nonspecific, semiquantitative or too laborious to be used in clinical practice. More recent methods are quantitative and...article 1993

Both the cyclooxygenase inhibitors acetylsalicylic acid and indomethacin enhanced PAI-1 induction. The combined cyclooxygenase-lipoxygenase inhibitor,...article 1992
