Gastric cancer (GC) is one of the most common cancers, with high incidences in East Asia. microRNAs (miRNAs) play essential roles in the carcinogenesis of GC. miR-20a was elevated in GC, while the potential function of miR-20a was poorly understood. miR-20a expression was examined in GC tissues and cell lines. The effects of miR-20a on the growth,(More)
Azithromycin loaded microspheres with blends of poly-l-lactide and ploy-D,L-lactide-co-glycolide as matrices were prepared by the atmosphere-solvent evaporation (ASE) and reduced pressure-solvent evaporation (RSE) method. Both the X-ray diffraction spectra and DSC thermographs demonstrated that poly-L-lactide existed in a crystalline form in the ASE(More)
BACKGROUND We introduced a new, safe and simple intracorporeal Billroth II (B-II) gastrojejunostomy technique using laparoscopic linear staplers with totally laparoscopic distal gastrectomy (TLDG) for gastric cancer. We further compared the short-term operative outcomes between intracorporeal B-II gastrojejunostomy with TLDG and extracorporeal B-II(More)
Notch signaling plays a critical role in the maintenance of intestinal homeostasis. The aim of the present study was to investigate the role of Notch signaling in the apoptosis of intestinal epithelial cells after intestinal ischemia reperfusion (I/R) injury. Male C57BL/6 mice were subjected to sham operation or I/R injury. Intestinal tissue samples were(More)
A high speed heavy duty palletizer can accomplish palletizing tasks efficiently and effectively. However, vibration problems are caused by the high speed and heavy duty of the palletizers at the same time. In this paper, we propose a mathematical method to illustrate how the palletizer will react to its moving speed and bearing duty. We analyze the normal(More)
To develop a new intradermal antigen delivery system by coating microneedle arrays with lipid bilayer-coated, antigen-loaded mesoporous silica nanoparticles (LB-MSN-OVA). Synthesis of MSNs with 10-nm pores was performed and the nanoparticles were loaded with the model antigen ovalbumin (OVA), and coated with a lipid bilayer (LB-MSN-OVA). The uptake of(More)
Colorectal cancer is the third most common cause of cancer-related mortality in the whole world (1). About one-third of colorectal carcinoma patients with acute colonic obstruction mandate emergency surgery (2). Current surgical options include intraoperative lavage, colonic segment resection involved with primary anastomosis, subtotal co-lectomy, colostomy(More)
In order to investigate the influence of silencing soluble epoxide hydrolase (sEH) with double-stranded small interfering RNA (siRNA) on cardiomyocytes apoptosis induced by doxorubicin (DOX), two plasmids containing siRNA sequences specific to sEH were constructed and transfected into the primary cultured cardiomyocytes by using FuGENE HD transfection(More)
The purpose of the present study was to examine the effects of oxidative stress on ventricular arrhythmias in rabbits with adriamycin-induced cardiomyopathy and the relationship between oxidative stress and ventricular arrhythmia. Forty Japanese white rabbits were randomly divided into four groups (n=10 in each): control group, metoprolol (a selective β1(More)
