The mechanical properties of nacre constituents from red abalone were investigated. Electron microscopy studies revealed that the tablets are composed of single-crystal aragonite with nanograin inclusions. Both nanoasperities and aragonite bridges are present within the interfaces between the tablets. By means of nanoindentation and axial compression tests,(More)
Dehydrins (DHNs) define a complex group of stress inducible proteins characterized by the presence of one or more lysine-rich motifs. DHNs are present in multiple copies in the genome of plant species. Although genome-wide analysis of DHNs composition and chromosomal distribution has been conducted in herbaceous species, it remains unexplored in woody(More)
N-terminal acetyltransferase (Nats) complex is responsible for protein N-terminal acetylation (Nα-acetylation), which is one of the most common covalent modifications of eukaryotic proteins. Although genome-wide investigation and characterization of Nat catalytic subunits (CS) and auxiliary subunits (AS) have been conducted in yeast and humans they remain(More)
The normal vasculature is maintained by a balance between angiogenic factors and anti-angiogenic factors. Recent studies have shown that pigment epithelium-derived factor (PEDF) can induce differentiation and inhibit angiogenesis of tumors. This study was designed to investigate the expression of PEDF and its roles in proliferation, adhesion and migration(More)
Vascular endothelial growth factor (VEGF) is one of the strongest regulators of physiological and pathological angiogenesis. VEGF receptor 2 (VEGFR-2), the primary receptor for VEGF, is thought to mediate major functional effects of VEGF. Previously, we have localized both VEGF and VEGFR-2 in human hair follicles. In this study, we further defined the(More)
PURPOSE To investigate the value of palliative gastrectomy and chemotherapy in a large series of patients with stage IV gastric cancer. METHODS A total of 389 patients were identified in survival analysis. Among which, 183 cases received palliative gastrectomy (PG) and 206 cases received unresectable operation, 184 cases received palliative chemotherapy(More)
OBJECTIVE To investigate the incidence of 1q21 amplification and 1p12 deletion, and analyze the correlation between these aberrations with disease progression, prognosis and outcome in patients with multiple myeloma (MM). METHODS Cytoplasm light chain immunofluorescence with simultaneous interphase fluorescence in situ hybridization (cIg-FISH) was used to(More)
BACKGROUND & OBJECTIVE The incidence of colorectal cancer is increasing in China, of which rectal cancer accounts for over 50%. Because of the limitation of pelvic cavity, the selection of surgical procedures, the proportion of sphincter saving and prognosis of male patients are different from those of female patients. This study was to analyze the(More)
This contribution considers the guaranteed cost control for a class of linear uncertain time-delay switched singular systems under arbitrary switching laws with a given quadratic performance index. Based on a Lyapunov function approach and a linear matrix inequality (LMI) technique, a sufficient condition on the existence of guaranteed cost state feedback(More)
Despite the large number of published papers analyzing the prognostic role of Ki-67 in NSCLC, it is still not considered an established factor for routine use in clinical practice. The present meta-analysis summarizes and analyses the associations between Ki-67 expression and clinical outcome in NSCLC patients. PubMed, Cochrane, and Embase databases were(More)
