BACKGROUND Luteolin (LUT), a kind of flavonoid which is extracted from a variety of diets, has been reported to convey protective effects of various diseases. Recent researches have suggested that LUT can carry out cardioprotective effects during ischemia/reperfusion (I/R). However, there have no reports on whether LUT can exert protective effects against(More)
OBJECTIVE To describe the expression profiles of FOXA1, DUSP6, and HA117 in different portions of the colon of patients diagnosed with Hirschsprung's disease (HSCR). METHODS Colon specimens were collected from 34 HSCR patients and grouped into 3 segments: proximal anastomosis, dilated segment and stenotic segment. Levels of FOXA1, DUSP6, and HA117 RNA(More)
OBJECTIVES Luteolin is a naturally occurring flavonoid found in many vegetables, fruits and medicinal plants. The migration and proliferation of vascular smooth muscle cells (VSMCs) are the critical pathological processes in various cardiovascular diseases, such as atherosclerosis. In this study, we investigated the effect of luteolin and its latent(More)
OBJECTIVE The goals of this study were to observe how luteolin protects endothelial cells (ECs) from injury stimulated by Angiotensin II (Ang II), investigate the role of vascular endothelial dysfunction in vascular smooth muscle cell proliferation and migration in vitro and investigate its primary mechanism of action. METHODS A non-contact coculture(More)
A general strategy, nonshadow deposition dominated colloidal lithography (NSCL), was proposed for the synthesis of two-dimensional (2D) ordered hollow sphere arrays of conductive materials. Gold, polypyrrole, CdS, and ZnO were taken as model materials to demonstrate the NSCL strategy, and built as 2D hollow sphere arrays successfully. In this strategy, a(More)
We report an electrochemical synthesis of two-dimensionally ordered porous Ni arrays based on polystyrene sphere (PS) colloidal monolayer. The morphology can be controlled from bowl-like to hollow sphere-like structure by changing deposition time under a constant current. Importantly, such ordered Ni arrays on a conducting substrate can be transferred(More)
Recent studies have demonstrated that diabetes impairs the phosphatidylinositol 3-kinase/Akt (PI3K/Akt) pathway, while insulin resistance syndrome has been associated with alterations of this pathway in diabetic rats after ischemia/reperfusion (I/R), and activation of C-jun N-terminal kinase (JNK) is involved. The present study was designed to investigate(More)
We report the synthesis of sphere-like α-Ni(OH)(2) nanoarchitecture by self-assembly with the aid of hexamethylenetetramine (HMT). The α-Ni(OH)(2) nanoarchitectures, with a diameter of several micrometres, are composed of many nanoflakelets about 10 nm in thickness. The influences of the reaction temperature, time, reagent, nickel salt and pH value on the(More)
Colloidal lithography is a low-cost, high-throughput, facile nanofabrication technique capable of producing a large variety of nanostructured arrays. In this letter, we report a methodology, named step-by-step colloidal lithography, using electrochemical deposition as a fabrication technique to sculpture various hexagonally packed 2D-ordered gold binary(More)
Monodispersed hierarchically structured V2O5 hollow spheres were successfully obtained from orthorhombic VO2 hollow spheres, which are in turn synthesized by a simple template-free microwave-assisted solvothermal method. The structural evolution of VO2 hollow spheres has been studied and explained by a chemically induced self-transformation process. The(More)
