96% (median: 0.42%; 95% CI: 0-89.0%). Blasts with 0.5% or fewer HLA-G expressing were defined as negative according to its expression in normal CD34(+)CD45(+) cells (n = 20, range: 0-0.5%; median: 0.13%; 95% CI: 0-0.42%). HLA-G expression status on leukemic blasts was not associated with the clinical parameters such as patient age at diagnosis, sex, sub-type of AML, percentage of blasts at diagnosis. Survival analysis revealed that HLA-G expression status on leukemic blasts is unrelated to the prognosis (p = 0.884). The mean overall survival time for the HLA-G negative and positive patients was 20.7

months (95% CI: Selleckchem AG-881 16.1-25.3) and 20.1 months (95% CI: 14.3-25.8), respectively. Taken together, our findings indicated that HLA-G expression is of no significance for the prognosis of patients with AML. (C) 2011 Elsevier Ltd. All rights reserved.”
“Aims Late gadolinium enhanced cardiovascular magnetic resonance (LGE-CMR) is a valuable test to detect myocardial damage in patients with sarcoidosis; however, the clinical significance of LGE in sarcoidosis patients with preserved left ventricular ejection fraction (LVEF) is not defined. We aim to characterize the prevalence of LGE, its associated cardiac findings, and its clinical implications in sarcoidosis patients with preserved Selleck BAY 73-4506 LVEF.\n\nMethods and results One hundred and fifty-two patients with biopsy proven extra-cardiac sarcoidosis, no

known cardiac sarcoidosis, and LVEF >= 50% referred for LGE-CMR were included in this observational study. The presence of LGE in the left ventricular myocardium was considered diagnostic for cardiac sarcoidosis. The cohort was divided into two groups based on the presence or absence of LGE. Twenty-nine patients (19%) had LGE involving 11 +/- 9% of the left ventricle. The modified Japanese

Ministry of Health and Welfare (JMHW) criteria for diagnosing cardiac sarcoidosis only had a sensitivity of 52% and specificity of 83% for identifying myocardial LGE in these patients. Compared with those patients without LGE, those with LGE had a higher heart rate (84 +/- 19 vs. 76 +/- 18 b.p.m., P = 0.002), greater prevalence of an abnormal electrocardiogram (76 vs. AG-120 Metabolism inhibitor 31%, P < 0.001), diastolic dysfunction (67 vs. 33%, P = 0.05), reduced right ventricular ejection fraction (49 +/- 8 vs. 55 +/- 6%, P = 0.012), and evidence of non-sustained ventricular tachycardia (33 vs. 6%).\n\nConclusions In patients with sarcoidosis and preserved systolic function, myocardial damage is commonly present and may increase the risk of ventricular tachy-arrhythmias. The JMHW Criteria were neither sensitive nor specific for predicting the presence of myocardial LGE.”
“Ameloblastin is processed by protease(s) during enamel formation. We tested the hypothesis that MMP-20 (enamelysin) catalyzes the cleavages that generate secretory-stage ameloblastin cleavage products.
