The elderly are susceptible to infections and show a decline in neutrophil (PMN) functions that are regulated by cytosolic calcium [Ca2+]i. This study measures [Ca2+]i in suspended and adherent PMN of young and elderly individuals by using flow cytometry, confocal microscopy, the bacterial peptide fMLP, and the fluorescent Ca2+ indicator(More)
BACKGROUND Markers of plaque destabilization and disruption may have a role in identifying non-STE- type 1 Myocardial Infarction in patients presenting with troponin elevation. We hypothesized that a plaque disruption index (PDI) derived from multiple biomarkers and measured within 24 hours from the first detectable troponin in patients with acute non-STE-(More)
BACKGROUND/AIMS The ideal hemoglobin target in chronic kidney disease remains unknown. Ultimately, individualized targets may depend upon the properties of the patient's endothelial and vascular milieu, and thus the complex relationships between these factors need to be further explored. METHODS Forty-six patients with a glomerular filtration rate (GFR)(More)
