Two plasminogen activator inhibitors (I and II) were demonstrated in human placenta. The complex between inhibitor I and tissue-type plasminogen activator was purified by immunoadsorption to solid-phase anti-activator antibodies. The purified complex (Mr 95.000) was used for immunization of mice and subsequent production of monoclonal antibodies. One(More)
This review discusses current knowledge of the complex interactions between amyloid-beta (A beta) peptide, the receptor for advanced glycation endproducts (RAGE), and inflammatory mediators, focusing on the roles of such interactions in the pathogenesis of Alzheimer's disease. As a ubiquitous cell-surface receptor, RAGE demonstrates enhanced expression in(More)
1. The fatty acid synthesis in isolated liver cells from fed rats was studied with tritiated water as the radioactive precursor. The cells incorporated 3H20 at a rate of 1.26 mumol per min per g packed cells. 2. Addition of ethanol caused a 20% decrease in the incorporation of tritium into fatty acids. The decrease was correlated to the increase in the(More)
Highly purified plasminogen-activator inhibitors of type 1 (PAI-1) and type 2 (PAI-2), low-Mr form, were compared with respect to their kinetics of inhibition of tissue-type (t-PA) and urokinase-type plasminogen activator (u-PA). The time course of inhibition of plasminogen activator was studied under second-order or pseudo-first-order conditions. Residual(More)
Eleven monoclonal antibodies and a polyclonal rabbit antiserum were evaluated with respect to reactivity with acetylcholinesterase (AChE, EC 3.1.1.7) from erythrocytes and brain. Employing our enzyme antigen immunoassay for AChE five selected antibodies were evaluated with regard to their clinical usefulness in the prenatal diagnosis of neural tube defects(More)
Two methods for quantitative determination of the high molecular weight glycoprotein, fibronectin, have been developed. Both methods are based on enzyme-linked immunoadsorbent (ELISA) techniques. In the first of the methods an antibody against fibronectin is used to trap the antigen. This double antibody technique can detect a slight decrease in the(More)
A new assay for functional plasminogen activator inhibitor 1 (PAI-1) in plasma was developed. The assay is based on the quantitative conversion of PAI-1 to urokinase-type plasminogen activator (u-PA)-PAI-1 complex the concentration of which is then determined by an ELISA employing monoclonal anti-PAI-1 as catching antibody and monoclonal anti-u-PA as(More)
Monoclonal antibodies were produced against human angiotensinogen. An enzyme linked immunosorbent assay (ELISA) was developed using a high affinity monoclonal antibody as catching antibody and a polyclonal rabbit anti human angiotensinogen antibody as detecting antibody in a "sandwich" ELISA. Linear range of the ELISA was 15-450 pmol/l of human(More)
Hypothalamic-pituitary-adrenocortical (HPA) function was assessed during normal daily work and family life in fifteen male brewery workers with a daily alcohol intake of 100 g or more for at least 10 years. Free urinary cortisol was determined during three baseline days and for 3 days during administration of dexamethasone 0.5 mg 6-hourly. All subjects had(More)
The aim of the present work was to clarify to what extent plasminogen activator inhibitor-1 (PAI-1) and plasminogen activator inhibitor-2 (PAI-2) contribute to the increase in plasma inhibition of tissue-type plasminogen activator (t-PA) observed during pregnancy. It was demonstrated that a monoclonal antibody against PAI-1 almost completely quenched(More)
