We have found that the imprinted H19 gene can be expressed either biallelically or monoallelically in the developing human placentae. H19 biallelic expression is confined to the placenta until 10 weeks of gestation, after which it becomes exclusively maternal, and does not affect allele-specificity or levels of IGF2 expression. The promoter region of H19 is(More)
When granulocytes are stimulated under certain clinical conditions, elastase is released therefrom and digests fibrin(ogen) independently of the plasmin system, which may also be mobilized simultaneously. Thus, discrimination of these 2 systems becomes urgent for the diagnosis and treatment of the underlying diseases. Using as immunogen a 97-kd(More)
Using urea-solubilized human fibrin monomer as an immunogen, we raised in mice a battery of monoclonal antibodies that reacted with the immunogen but not with urea-treated or native fibrinogen. Although they all failed to react with acid-solubilized fibrin monomer (acid-FM) alone, an antibody designated as IF-43 was found to recognize acid-FM, which was(More)
beta(2)-Glycoprotein I (beta(2)GPI) consists of five tandem repeated domains (I, II, III, IV, and V). The nicked form of beta(2)GPI (N-beta(2)GPI ) which was cleaved by plasmin in vitro at Lys 317-Thr 318 in domain V, showed reduced affinity for the negatively charged phospholipids, especially cardiolipin (CL). Recently, the N-beta(2)GPI was detected in the(More)
An acid-stable alpha-amylase (AA) was purified from an acidic extract of citric acid-koji (A. usamii var.). The N-terminal sequence of the first 20 amino acids of the enzyme was identical with that of AA from A. niger, but the two enzymes differed in molecular weight. HPLC analysis for identifying the anomers of products indicated that the AA hydrolyzed(More)
Among six monoclonal antibodies raised against the human plasmin-alpha 2-plasmin inhibitor complex (PPI), three antibodies were found to recognize the plasmin part (group 1) and another three the alpha 2-plasmin inhibitor (alpha 2-PI) part (group 2) of the complex. One of the group-1 monoclonal antibodies, designated JIPPI-3, specifically reacted with a(More)
BACKGROUND Intracranial pressure changes during head impact cause brain injuries such as vasogenic edema and cerebral contusion. However, the influence of impulsive pressure on endothelial function has not yet been fully studied in vitro. In this study, we developed a pressure loading device that produced positive and negative pressures by modifying an in(More)
