The fibrinolytic potential of the vasculature is modulated primarily by the availability and activity of plasminogen activators, which convert the zymogen plasminogen into the active fibrin-degrading enzyme plasmin. The activities of these key regulatory enzymes are directly neutralized by their primary endogenous inhibitor, plasminogen activator(More)
—In contrast to standard cameras, which produce frames at a fixed rate, event cameras respond asynchronously to pixel-level brightness changes, thus enabling the design of new algorithms for high-speed applications with latencies of microseconds. However, this advantage comes at a cost: because the output is composed by a sequence of events, traditional(More)
We have previously reported that recombinant human interleukin-1 (IL-1) stimulates matrix erosion in bovine nasal cartilage explants (R. J. Smith et al., Inflammation 13, 367-382, 1989). This action of IL-1 is believed to be caused by matrix-degrading neutral proteinases produced by activated chrondrocytes. Accordingly, we investigated the effects of(More)
4,4'-Methylenedianiline (MDA) is an important chemical intermediate in the production of isocyanates and polyurethane elastomers and polymers. The health hazards from acute inhalation exposure to the aerosols were evaluated. Guinea pigs of albino and pigmented strains were exposed nose-only to the aerosols of MDA in polyethylene glycol 200 (PEG) solution.(More)
Cats with induced sterile abscesses developed a hematologic disorder consistent with anemia of inflammation. Serum iron concentrations decreased while the abscess was present, but erythropoietin concentrations did not change significantly. Cobalt administration to control (healthy) cats resulted in polycythemia, reticulocytosis, and hyperferremia. Cats with(More)
Young adult rats were given three weekly intratracheal instillations of 30 mg of raw oil shale or spent oil shale suspended in 1.0 ml sterile physiological saline. Positive control groups received similar instillations of 30 mg or 5 mg of quartz. Animals were sacrificed and tissue samples taken for histopathology and biochemical analyses at 3 weeks, 7(More)
