Plexin C1 marks liver cancer cells with epithelial phenotype and is overexpressed in hepatocellular carcinoma
No full textBackground and Aims. Hepatocellular carcinoma is an aggressive malignancy of the liver and is ranked as the sixth most common cancer worldwide. There is still room for novel markers to improve the diagnosis and monitoring of HCC. Our observations in cancer databases that PLXNC1 is upregulated in HCC led us to investigate the expression profile of Plexin C1 mRNA and protein in HCC cell lines and tissues. Methods. A recombinant protein encompassing part of the extracellular domain of Plexin C1 was used as an antigen for monoclonal antibody development. Transcript and protein levels of Plexin C1 in HCC cell lines were determined by RT-qPCR and Western blotting, respectively. In vivo evaluation of Plexin C1 expression in HCC tissues was accomplished by immunohistochemistry studies in tissue microarrays. Results. A monoclonal antibody, clone PE4, specific to Plexin C1, was generated. In silico and in vitro analyses revealed a Plexin C1-based clustering of well-differentiated HCC cell lines. Staining of HCC and nontumoral liver tissues with PE4 showed a membrane-localized overexpression of Plexin C1 in tumors (p=0.0118). In addition, this expression was correlated with the histological grades of HCC cases. Conclusions. Plexin C1 distinguishes HCC cells of epithelial characteristics from those with the mesenchymal phenotype. Compared to the nontumoral liver, HCC tissues significantly overexpress Plexin C1. The newly generated PE4 antibody can be evaluated in larger HCC cohorts and might be exploited for the examination of Plexin C1 expression pattern in other epithelial malignancies.</p
Performance maximization of network assisted mobile data offloading with opportunistic Device-to-Device communications
No full textA. Serdar Tan (MEF Author)Mobile data traffic inside mobile operator's infrastructure is increasing exponentially every year. This increasing demand forces mobile network operators (MNOs) to seek for alternative communication methods in order to relieve the traffic load in base stations, especially in highly populated and crowded environments. Network assisted data offload and Device-to-Device(D2D) communications are two prominent methods to help MNOs solve this problem. In this study, a data offload framework is developed that incorporates network assisted multiple attribute decision making (MADM) for best network selection and D2D communications for exploiting user proximity in crowded environments. The performance of the framework is evaluated with simulation results as well as analytic solutions and performance bounds. The simulation results indicate the superiority of incorporating network-based information besides user-based information in offloading decisions and demonstrates the significant benefits of D2D communications when the density of D2D users is properly adjusted. The simulation results depict that up to 168% and 200% increase in user satisfaction and throughput can be achieved under high network load scenarios at optimal D2D density. (C) 2018 Elsevier B.V.

Analgesics effect of intra-articular bupivacaine injection on pain score in anterior cruciate ligament surgery: a randomized clinical trial
No full text<p>Abstract Background: The aim of this study was to examine the effects of injection timing and drainage clamps on patient pain scores in intra-articular local anesthetic applications after arthroscopic anterior cruciate ligament (ACL) reconstruction. Materials and Methods: Forty patients undergoing arthroscopic ACL reconstruction were randomly allocated to one of the four study groups according to the time of the intraarticular bupivacaine (20 ml) injection and the presence of the drainage clamps as follows: Preoperative injection group (PO) received bupivacaine injection 20 minutes prior to the operation, Drain Open group (DO) received bupivacaine injection following the operation while the hemovac drain was open, Drain closed group (DC) received bupivacaine injection following the operation while the hemovac drain was closed, and the control group in which the subjects did not receive any intraarticular injections. Results: The VAS score for postoperative joint pain was lowest in PO group among all groups at the postoperative 2nd hour. At the 4th and the 6th postoperative hours the VAS score for postoperative joint pain was similar in the PO and DC groups and was lower than that of the DO group and the controls. However, the VAS score at the postoperative 12th hour was lower in DO and DC groups that the PO group and the controls. Conclusions: The VAS score for postoperative joint pain changes with respect to the timing of the injection and the presence or absence of drainage. Key words: intra-articular, bupivacaine, postoperative pain scores</p>

No full textThe authors of this paper informed us about the existence of an error. Remzi Akturk has been listed as a co-author in this article. In order to prevent ethical issues, all authors of this article agreed that he should be listed as a guest author instead of co-author because he did not contribute in data collecting. Because of that, the name Remzi Akturk is removed from the author's list in this article. All authors send a signed agreement that the name of Remzi Akturk must be removed from the author's list. According to this, the list of the authors on pages 115 and 119 "Serdar Serinsoz, Remzi Akturk, Sibel Bayramoglu" should be replaced with: "Serdar Serinsoz, Sibel Bayramoglu"
