TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Activation of the endotoxin (LPS) receptor, CD14, leads to tumor necrosis factor-alpha (TNF) production. Plasma LPS activity is elevated in patients with severe chronic heart failure (CHF). An anti-CD14 antibody, IC14, blocks TNF production in healthy volunteers. It is not known whether IC14 prevents TNF production in CHF patients.', 'Blood from 20 CHF patients (age 64+/-2.1 years, NYHA class 2.2+/-0.1, LVEF 27+/-3%, mean+/-SEM) was pre-incubated with 0.5, 1.0, 5.0, 10 and 50 microg/mL IC14 for 1 h followed by incubation with 1 or 10 ng/mL LPS for 6 h. Fourteen subjects served as controls (58+/-2.4 years). LPS-stimulated TNF release was 76% and 60% greater at 1 and 10 ng/mL LPS, respectively, in CHF patients versus controls (p=0.07 and p=0.008). IC14 at concentrations of 5.0, 10 and 50 microg/mL substantially reduced TNF production in response to stimulation with LPS (all p<0.05). CD14 receptor density was similar in patients and controls. In controls, but not in CHF patients, there was a positive correlation between CD14 receptor density and TNF production (r=0.61, p=0.03).'] Does the anti-CD14 antibody IC14 suppress ex vivo endotoxin stimulated tumor necrosis factor-alpha in patients with chronic heart failure?
OUTPUT:
