MicroRNAs (miRNAs) are aberrant in many human tumors which can be transferred to immune cells by tumor-derived exosomes. Dendritic cells (DCs) play an important role in activation of immune response. However, the effect of tumor-derived exosomes on toll-like receptor (TLR) in DCs remains unclear. We investigated the influence of pancreatic cancer derived(More)
Leaderless translation is prevalent in haloarchaea, with many of these leaderless transcripts possessing short 5'-untranslated regions (UTRs) less than 10 nucleotides. Whereas, little is known about the function of this very short 5'-UTR. Our previous studies determined that just four nucleotides preceded the start codon of hsp70 mRNA in Natrinema sp. J7,(More)

BACKGROUND Prediction of postoperative survival for hilar cholangiocarcinoma (HCCA) remains difficult although there have been a variety of clinical classification and staging systems. This study was designed to validate and compare some of the major HCCA staging systems in use today. In addition, we sought to build up a new staging system modified from(More)
The recent progress of compressive sensing (CS) theory shows that perfect reconstruction is possible when the data are sampled randomly and compressed greatly. This revolutionary theory strongly advocates the irregular sampling pattern in the process of seismic data acquisition, leading to a highly reduced acquisition cost. The complete seismic record can(More)
The aim of this study was to investigate the expression of Delta-like ligand 4(DLL4) and Endoglin(CD105) labeled microvessel density(MVD) in pancreatic ductal adenocarcinoma (PDAC) and evaluate their correlation with major clinicopathologic features and patients’ survival. Forty-two pancreatic cancer and 20 normal pancreatic tissues were included in the(More)
Memory is very important in the present era of Internet of Thing (IoT) and Big Data, while Resistive Random Access Memory (RRAM) is a key member in the family of non-volatile memory. However, in the development of high density RRAM memory array, self-heat effect (SHE) as well as thermal crosstalk must be understood and controlled during its operation. In(More)
The cryopreservation of immature oocytes at the germinal vesicle (GV) stage would create an easily accessible, non-seasonal source of female gametes for research and reproduction. The present study investigated the ability of ovine oocytes vitrified at the GV stage using a cryoloop to be subsequently matured, fertilised and cultured in vitro to(More)
