TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Systemic Sclerosis (SSc) is characterized by a microvascular damage due to an impairment of different angiogenic and angiostatic factors. Aim of this study was to measure plasma levels of nine molecules involved in these vascular processes in a group of SSc patients, respect to healthy controls (NC).', 'Sixty-five patients (M/F = 2/63; mean age = 57.29 yrs; mean disease duration = 9,63 yrs) with established SSc according to ARA criteria, and sixteen age- and sex-matched NC were enrolled. Plasma levels of vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2), platelet derived growth factor- bb (PDGF-BB), platelet endothelial cellular adhesion molecule-1 (PECAM-1), leptin, hepathocyte growth factor (HGF), follistatin, granulocyte-colony stimulating factor (G-CSF) and interleukin 8 (IL-8) were measured using commercially available immunoassay kits (Human Angiogenesis 9-Plex Panel, Bio-Rad Laboratories).', "We detected a significant increase of Ang-2 (median value 1315.4 pg/ml vs 538.73 pg/ml; p=0.0292), HGF (median value 2886.16 pg/ml vs 1296.16 pg/ml; p=0.0001), IL-8 (median value 32.22 pg/ml vs 16.86 pg/ml; p=0.02), leptin (median value 32589,1 pg/mg vs 10679.61 pg/ml; p=0.0065), PDGF-BB (median value 7258.6 pg/ml vs 2913.44 pg/ml; p=0.0005), PECAM-1(median value 21681.81 pg/ml vs 10354.53 pg/ml; p=0.0003) and VEGF (median value 236.72 pg/ml vs 122.905 pg/ml; p=0.0073) in patients with SSc respect to NC. Higher levels of PDGF-BB (p=0.03) and PECAM-1 (p=0.05) were found in patients with digital ulcers while lower levels of PECAM-1 were found in patients with pulmonary hypertension (PH). Besides levels of IL-8 were higher in patients with PH (p=0.04) and lower in those with pulmonary fibrosis (p=0.5), while levels of Ang-2 were higher in those with a 'late' nailfold video-capillaroscopy (NVC) pattern respect to those with an 'early/active' one (p=0.05). Moreover, plasma levels of VEGF (p=0.02) and PDGF-BB (p= 0.04) were significantly higher in those patients positive for anti-topoisomerase 1 antibodies."] Are abnormal plasma levels of different angiogenic molecules associated with different clinical manifestations in patients with systemic sclerosis?
OUTPUT:
