Graphene has been demonstrated in many biomedical applications and its potentials for neural interfacing. Emerging concerns on graphene, as a biomedical material, are its biocompatibility and how biologically targeted tissue/cells respond to it. Relatively few studies attempted to address the interactions of graphene or its derivatives with the(More)
Although the study of imprinted genes in human development is very important, little is known about their expression and regulation in the early differentiation of human tissues due to lack of an appropriate model. In this study, a Chinese human embryonic stem (hES) cell line, SHhES1, was derived and fully characterized. Expression profiles of human(More)
Adhesions of cells to extracellular matrix and adjacent cells are mediated by integrins and VE-cadherin, respectively. Although these adhesion processes play crucial roles in vascular cell migration and angiogenesis, it remains unclear as to how they are coordinated to regulate cellular functions. We report here that integrin engagement by treating bovine(More)
Delta-like ligand 4 (DLL4)-Notch signaling plays a key role in tumor angiogenesis, but its prognostic value in patients with pancreatic ductal adenocarcinoma (PDAC) remains unclear. Our aim was to determine whether high DLL4 expression is correlated with poor prognosis after curative resection for PDAC. Surgical specimens obtained from 89 patients with PDAC(More)
Genome-wide expression analysis of embryonic development provides information that is useful in a variety of contexts. Here, we report transcriptome profiles of human early embryos covering development during the first third of organogenesis. We identified two major categories of genes, displaying gradually reduced or gradually increased expression patterns(More)
OBJECTIVES To study and analyze the causes of chylous leakage after pancreaticoduodenectomy. METHODS We retrospectively analyzed 381 patients who underwent pancreaticoduodenectomy (including pylorus-preserving pancreaticoduodenectomy) in Shanghai Chang Hai Hospital Affiliated to the Second Military Medical University, Shanghai, China between January 2010(More)
Understanding the complexity and dynamics of cancer cells in response to effective therapy requires hypothesis-driven, quantitative, and high-throughput measurement of genes and proteins at both spatial and temporal levels. This study was designed to gain insights into molecular networks underlying the clinical synergy between retinoic acid (RA) and arsenic(More)
BACKGROUND This study was designed to describe the precise anatomic venous tributaries of the superior mesenteric vein with special emphasis on the superior right colic vein (SRCV), which is seldom mentioned in the literature. METHODS Nine adult cadavers were dissected to define the venous tributaries of the superior mesenteric vein. The SRCV, middle(More)
Atherosclerosis occurs preferentially at vascular curvature and branch sites where the vessel walls are exposed to fluctuating shear stress and have high endothelial permeability. Endothelial permeability is modulated by intercellular adhesion molecules such as VE-cadherin. This study was designed to elucidate the effects of different flow patterns on the(More)
Pancreatic ductal adenocarcinoma (PDAC) ranks fourth on the list of cancer-related causes of death. Deregulation or dysfunction of miRNAs contribute to cancer development. In this study, we found that low miR-545 level and high RIG-I protein in PDAC tissues were both correlated with low survival rate. MiR-545 up-regulation inhibited PDAC cell lines growth(More)
