Endothelial cells express very low density lipoprotein receptor (VLDLr). Beyond the function as peripheral lipoprotein receptor, other roles of VLDLr in endothelial cells have not been completely unraveled. In the present study, human umbilical vein endothelial cells were subjected to hypoxia, and VLDLr expression, endoplasmic reticulum (ER) stress, and(More)
BACKGROUND/AIMS The acquisition of resistance to 5-FU is one of the most prominent obstacles to successful chemotherapy, and the mechanisms underlying the resistance are not fully understood. The aim of this study is to identify novel mediators of 5-FU resistance in colon cancer cells. METHODOLOGY LoVo colon cancer cells were induced to 5-FU resistance in(More)
A constitutive activation of protein kinase B (AKT) in a hyper-phosphorylated status at Ser473 is one of the hallmarks of anti-EGFR therapy-resistant colorectal cancer (CRC). The aim of this study was to examine the role of cytosolic phospholipase A2α (cPLA2α) on AKT phosphorylation at Ser473 and cell proliferation in CRC cells with mutation in(More)
Recently, transition metal oxides, such as ruthenium oxide (RuO₂), manganese dioxide (MnO₂), nickel oxides (NiO) and cobalt oxide (Co₃O₄), have been widely investigated as electrode materials for pseudo-capacitors. In particular, these metal oxides with mesoporous structures have become very hot nanomaterials in the field of supercapacitors owing to their(More)
BACKGROUND Salvianolic acid A (SalA) has been shown to confer robust protection against endothelial injury. VLDL receptor is expressed at high levels on the endothelial surface, however its biological effect on endothelial cells has not yet been completely elucidated. Here, we investigated molecular effects of SalA on endothelial VLDL expression and barrier(More)
In order to research the statistical properties of Gaussian beam propagation through an arbitrary thickness random phase screen for adaptive optics and laser communication application in the laboratory, we establish mathematic models of statistical quantities, which are based on the Rytov method and the thin phase screen model, involved in the propagation(More)
BACKGROUND Gastric plication (GP) and sleeve gastrectomy (SG) are 2 restrictive bariatric surgeries that are associated with weight loss and health improvement in patients with obesity. However, differences in how these procedures exert their effects have not been systematically evaluated and compared between techniques. OBJECTIVES To investigate the(More)
Graphene oxide (GO) was doped into four polymers films: Poly(methyl methacrylate) (PMMA), polystyrene (PS), polycarbonate (PC), and polyacrylonitrile (PAN). Following that, their optical limiting properties were investigated at 532 nm. In order to make GO hydrophobic, the lipophilic alkyl chains were connected to GO. The results showed that GO/PAN composite(More)
BACKGROUND Preservation of pancreatic beta cell function has been increasingly appealing in the treatment of type 2 diabetes. Evidence is still limited on how bariatric surgery affects pancreatic beta cell apoptosis. SETTING University medical center. OBJECTIVE The study aimed to investigate the effect of a major component of Roux-en-Y gastric bypass,(More)
