“There are several reports on the ability aphasic patients have to sing familiar songs, despite having severe speech impairments. Based on these observations it was also suggested that singing might improve speech production. However, recent experimental studies with aphasic patients found no evidence to illustrate that singing improves word production under controlled experimental conditions. This study investigated the role of singing during repetition of word phrases in a patient severely affected with non-fluent aphasia (GS) who had an almost complete lesion of the left hemisphere. GS showed a pronounced increase in the number of correctly reproduced words during singing as compared to speaking excerpts of familiar lyrics. This dissociation between singing and speaking was not seen for novel song

lyrics, regardless of whether these were coupled with an unfamiliar, a familiar, or a spontaneously generated melody during the singing conditions. These findings propose that singing might help word phrase production in at least some cases of severe expressive aphasia. However, the association of melody and text in long-term memory seems to be responsible for this effect. (C) 2008 Elsevier Ltd. All rights reserved.”
“Background/Aims: Bone marrow-derived endothelial

progenitor cells (EPCs) are believed to contribute to endothelial repair after vascular ABT-737 in vitro damage. To investigate the potential for microvascular repair in patients with ANCA-associated vasculitis (AAV), we conducted a cross-sectional study determining the number of circulating EPCs in patients with AAV, chronic uremia, atherosclerosis, and in healthy volunteers. Methods: The number of circulating EPCs was determined by colony-forming assay in 41 patients with AAV, 15 hemodialysis Orotic acid patients (without vasculitis), 13 patients with peripheral arterial occlusive disease (PAOD), and 25 healthy controls. Results: Patients with AAV had a significantly lower number of CFU-Hill than healthy subjects (median 0.3 vs. 19.5 CFU-Hill/ml blood, p < 0.0001), but not than patients on hemodialysis or with PAOD. Neither institution of treatment nor entering remission increased the number of EPCs in AAV patients. The number of EPCs did not correlate with markers of disease activity. AAV patients with glomerular filtration rate <15 ml/min had an even lower number of circulating EPCs than patients with better preserved renal function (median 0.05 vs. 1.2 CFU-Hill/ml, p = 0.015) and patients with anti-MPO positivity had a trend towards a higher number of EPCs than patients with anti-PR3 antibodies (median 3.1 vs. 0.18 CFU-Hill/ml, p = 0.06).
