We constructed and tested a series of cloning vectors designed to facilitate protein production and purification in Dictyostelium discoideum (Dd). These vectors carry the origin of replication of the Dd high-copy-number plasmid Ddp2, expression cassettes consisting of the strong, constitutive actin (act15) or the inducible discoidin (disI gamma) promoters,(More)
The interaction of the nucleotide-free molecular chaperone DnaK (Hsp70) from Escherichia coli with nucleotides was studied under equilibrium and transient kinetic conditions. These studies used the intrinsic fluorescence signal of the single tryptophan residue (Trp102) of DnaK, or of novel fluorescent nucleotide analogs of ADP and ATP,(More)
In spite of good correlations between cardiac output measurements by impedance and established invasive procedures (dye- and thermo-dilution) reported by numerous authors it is doubtful uptil now whether calculations of stroke volume according to the formula of Kubicek et al. (1974) can provide absolutely reliable results. The origin of the dz/dt curve and(More)
OBJECTIVES To evaluate the safety and potential efficacy of antithrombin III (AT III) in reducing mortality in patients with severe sepsis. DESIGN Prospective, randomized, placebo-controlled, double-blind, phase II, multicenter, multinational clinical trial. SETTING Seven academic medical center intensive care units (ICU) in Belgium, Denmark, the(More)
The extent of myocardial damage occurring during acute myocardial infarction is time dependent, and there is abundant evidence from most clinical trials that mortality reduction is greatest in patients treated early with thrombolytic agents, although beneficial effects have been shown with treatment initiated up to 12 h after onset of symptoms. All studies(More)
Length of intensive care therapy and the total length of stay in hospital are important determinants of hospital costs. We therefore analysed the correlation between score parameters of SAPS-II with the time spent in the intensive care unit (ICU), and also in the hospital, for 604 general medical intensive care patients (ICU group) and 510 coronary care(More)
OBJECTIVE To evaluate the applicability of the Simplified Acute Physiology Score (SAPS II) for coronary care patients. DESIGN Prospective observational cohort study. SETTING Medical ICU of a community teaching hospital. PATIENTS 1587 consecutive patients admitted over a period of 18 months. MEASUREMENTS AND MAIN RESULTS Patients were divided in two(More)
Fenoldopam, a newly developed intravenous dopaminergic DA1 receptor agonist, was used in an open, prospective study for blood pressure control in 12 patients presenting with hypertensive crisis. At a dose of 0.2-0.5 microgram kg-1 min-1 fenoldopam decreased systolic blood pressure from 209 +/- 13 to 151 +/- 17 mmHg and diastolic blood pressure from 114 +/-(More)
