Red Blood Cell Transfusion and Surgical Site Infection After Colon Resection Surgery: A Cohort Study
Authors: Mazzeffi Michael , Tanaka Kenichi , Galvagno Samuel 
Published: May 2017

BACKGROUND:
Surgical site infections (SSIs) after colon surgery remain a critical safety issue. Patients with an SSI have an increased risk of death, prolonged hospitalization, and increased costs of care. Red blood cell (RBC) transfusion is given during the perioperative period to increase blood oxygen delivery, but it is associated with complications, including infection. We hypothesized that RBC transfusion would be associated with increased SSI risk in patients undergoing colon resection surgery.

METHODS:
A retrospective cohort study was performed using the 2014 National Surgical Quality Improvement Program participant use file. Patients who had colon resection surgery were identified using current procedural terminology codes. The association between perioperative RBC transfusion and superficial and deep incisional SSIs, organ space SSIs, and postoperative septic shock was modeled using logistic regression with propensity score analysis.

RESULTS:
Of 23,388 patients who had colon resection surgery, 1845 (7.9%) received perioperative RBC transfusion. After controlling for confounders with propensity score analysis and inverse probability of treatment weighting, RBC transfusion had no apparent association with superficial incisional SSI (odds ratio [OR], 1.18; 99% confidence interval [CI], 0.48–2.88) or deep incisional SSI (OR, 1.47; 99% CI, 0.23–9.43). However, RBC transfusion appeared to be associated with increased risk of organ space SSI (OR, 2.93; 99% CI, 1.43–6.01) and septic shock (OR, 9.23; 99% CI, 3.53–24.09).

CONCLUSIONS:
RBC transfusion has no apparent association with increased risk for incisional SSIs, but may be associated with increased risk for organ space SSI and septic shock after colon resection surgery.
Overview of mosquito-borne diseases and prevention strategies
Authors: Graham Sharon 
Published: May 2017

Most travellers will be aware of malaria, yet many other diseases can be spread through insect bites. Sharon Graham describes the main diseases and their geographical spread, and advises on the best protection behaviours nurses can recommend to travelling patients The focus of mosquito-borne disease generally centres on the biggest killer – malaria – but the public has recently become aware of other diseases that the small biting insect can transmit to travellers. One that has drawn much media attention is the Zita virus, with last year's outbreak in South America resulting in the World Health Organization declaring a global public health emergency. This article aims to raise awareness of other carriers and diseases, and to enable nurses advising patients on travel health to provide up-to-date information on prevention and avoidance strategies.

Abstract
This work introduces a simple and versatile method for researching the concentration gradient generator (CGG) which can present the arbitrary approximate linear and quadratic concentration gradient curves output. The concentration gradients of arbitrary approximate linear curves with two inlets and arbitrary quadratic curves in the CGG with three inlets are obtained with the corresponding flow velocities. The CGG was simulated basing on the finite element method (FEM). The fluid-dynamic and mass-transport about the CGG was studied. Moreover, the feasibility of simulation was clearly verified by an experiment which two microfluidic chips of CGG on the PMMA substrate were processed using CNC engraving and milling machine. The paper successfully demonstrates the controllability of concentration gradient profiles in CGG with two inlets and three inlets. The study on the CGG can help the trends study of cell and molecule in different samples in the biochemical engineering.

Published: May 2017

Abstract3D Eulerian-Eulerian model was applied to simulate the gas-liquid two-phase flow in a stirred tank of dual Rushton turbines using computational fluid dynamics (CFD). The effects of two different bubble treatment methods (constant bubble sizevs. population balance model, PBM) and two different coalescence models (Luo modelvs. Zaichik model) on the prediction of liquid flow field, local gas holdup or bubble size distribution were studied. The results indicate that there is less difference between the predictions of liquid flow field and gas holdup using the above models, and the use of PBM did not show any advantage over the constant bubble size model under lower gas holdup. However, bubble treatment methods have great influence on the local gas holdup under larger gas flow rate. All the models could reasonably predict the gas holdup distribution in the tank operated at a low aeration rate except the region far from the shaft. Different coalescence models have great influence on the prediction of bubble size distribution (BSD). Both the Luo model and Zaichik model could qualitatively estimate the BSD, showing the turning points near the impellers along the height, but the quantitative agreement with experiments is not achieved. The former over-predicts the BSD and the latter under-predicts, showing that the existing PBM models need to be further developed to incorporate more physics.
Active Power Control of Grid Tied SPV System with DSTATCOM Capabilities
Authors: Hussain Ikhlaq 
Published: May 2017

AbstractThis paper presents an active power control of SPV (Solar Photovoltaic) grid tied system with the DSTATCOM (Distribution Static Compensator) capabilities using recursive least square (RLS) control algorithm with IC (Incremental Conductance) maximum power point tracking. The system serves dual purpose of working as a SPV-DSTATCOM and DSTATCOM in presence and absence of solar power, respectively. The SPV-DSTACOM provides compensating currents along with active current component thus fulfilling active power demand of connected load and feeds active power to the grid along with improving the power quality. Moreover, when the solar power is not available during night or low solar irradiation conditions, the system works as a DSTATCOM providing compensating current which improves the power quality of the system during load unbalance, harmonics and reactive power. A RLS based adaptive algorithm is used to do these functions at good convergence than conventional LMS (Least Mean Square) algorithm. Thus, the proposed system is capable to meet peak power demand when the solar energy is available and it improves the system power quality during day and night. The system responses under varying conditions is demonstrated on s developed prototype.
A Comparative Study of Combined Microwave Techniques for Longan (Dimocarpus longan Lour.) Drying with Hot Air or Vacuum
Authors: Apinyavisit Krit , Nathakaranakule Adisak , Soponronnarit Somchart , Mittal Gauri S. 
Published: May 2017

Abstract
The aim of this study is to find a better drying method to replace conventional hot air drying (HAD) in terms of faster, energy efficient and better product quality. Two alternative drying techniques, microwave combined with hot air drying (MHD) and microwave vacuum drying (MVD), are compared in this study to dry peeled and destoned longan fruit. Both MHD and MVD reduced the drying time up to 48 % and energy consumption as compared to HAD. These techniques provided lower product redness, yellowness and shrinkage but higher lightness and porous structure as compared to HAD. MVD reduced hardness and toughness of the dried product. MHD provided the highest preference score in terms of colour and shape and was as acceptable as the commercial product dried by HAD. MHD is the most suitable method for longan drying.

Published: May 2017

Abstract
Polysaccharides from Zizyphus jujube cv. Muzao (ZMP) were extracted by ultrasonic-assisted extraction with acidic buffer. The chemical composition and antioxidant and anti-inflammatory activities of ZMP were evaluated. The results revealed that ZMP had a molecular weight of 89.90 kDa and consisted of arabinose, galactose, glucose, rhamnose, and mannose, with molar percentages of 4.52 %, 2.64 %, 1.04 %, 0.49 %, and 0.41 %, respectively. Based on Fourier-transform infrared spectroscopy, ZMP belonged to the type I rhamnogalacturonans family. In vitro antioxidants assays revealed that ZMP had remarkable antioxidant activity in a dose-dependent manner. Proinflammatory cytokines, such as interleukin-6 and tumor necrosis factor alpha, were suppressed by ZMP in lipopolysaccharide-treated RAW264.7 cells. Overall, the results revealed that ZMP has potential applications as a natural anti-inflammatory agent.

Abstract
This paper presents an investigation into the performance of real-time Global Navigation Satellite Systems (GNSS) Precise Point Positioning (PPP) in New Zealand. The motivation of the research is to evaluate the feasibility of using PPP technique and a satellite based augmentation system such as the Japanese Quasi-Zenith Satellite System (QZSS) to deliver a real-time precise positioning solution in support of a nation-wide high accuracy GNSS positioning coverage in New Zealand. Two IGS real-time correction streams are evaluated alongside with the PPP correction messages transmitted by the QZSS satellite known as MDC1. MDC1 corrections stream is generated by Japan Aerospace Exploration Agency (JAXA) using the Multi-GNSS Advanced Demonstration tool for Orbit and Clock Analysis (MADOCA) software and are currently transmitted in test mode by the QZSS satellite. The IGS real-time streams are the CLK9B real-time corrections stream generated by the French Centre National D’études Spatiales (CNES) using the PPP-Wizard software, and the CLK81 real-time corrections stream produced by GMV using their MagicGNSS software. GNSS data is collected from six New Zealand CORS stations operated by Land Information New Zealand (LINZ) over a one-week period in 2015. GPS and GLONASS measurements are processed in a real-time PPP mode using the satellite orbit and clock corrections from the real-time streams. The results show that positioning accuracies of 6 cm in horizontal component and 15 cm in vertical component can be achieved in real-time PPP. The real-time GPS+GLONASS PPP solution required 30 minutes to converge to within 10 cm horizontal positioning accuracy.

Published: May 2017

Abstract
In this paper an overview on the inclusive spatial design tools providing equal access to waterfront landscapes for tourists living with disabilities will be given. The focus is on close-to-natural areas which are popular because of their recreational potential. These areas present special natural and landscape values, and mostly are ecologically vulnerable. In these important ecological surroundings human presence and landscape values must be harmonized.
Environmental conditions, legal requirements and the economic situation can limit the opportunity for comprehensive access, but keep disability in mind while designing and maintaining these sites is a potential to provide wider access to the waterfront tourist destinations. We are about to present model solutions keeping the environment totally or mostly in its original, natural condition, but allowing recreational activities in the site at the same time.
Do Valuation Multiples Reflect a Size Effect?
Authors: Cornell Bradford , Gokhale Rajiv 
Published: May 2017

Abstract
In this paper, we empirically examine whether there is evidence to support the hypothesis that a size premium is impounded in valuation multiples. Overall, we find essentially no evidence to support the hypothesis. One interpretation of this finding is that there is no size effect in current U.S. data. If that is true, then size premiums should not be added to the discount rate and there is no potential inconsistency with the market multiples approach. However, if an appraiser chooses to add a size premium to the discount rate based on historical return data such as that reported by Ibbotson, it raises the possibility the DCF value indicator will be inconsistent with the value indicator based on market multiples. Given the fact that virtually all corporate appraisals include both a DCF and a market multiples analysis our work suggests that the two approaches should be blended with care in situations where a size premium is contemplated.
Acceleration of the global coastal sea level rise during the 20th century re-evaluated
Authors: Bâki Iz H. 
Published: May 2017

Abstract
In contrast to some of the recent investigations, this study shows that far less number of tide gauge stations experienced statistically significant accelerations in sea level rise during the 20th century. Twenty-seven tide gauge stations with century long data were analyzed for the presence of an acceleration in global sea level rise using a kinematic model inclusive of a secular trend, acceleration, and compounded periodicities with autocorrelated random effects. Eight out of twenty-seven stations revealed statistically significant but slow sea level rise acceleration (p<0.01) within the 0.01-0.02 mm/yr2 range compared to the sixteen stations with accelerations estimated using the models by the previous investigations,which did not account for the compounded periodicities and autocorrelations in sea level changes.
Metadiscourse and Topic Introductions in an Academic Lecture: A Multimodal Insight
Authors: Bernad-Mechó Edgar 
Published: May 2017

AbstractThis paper is part of a larger scale project where I explore the structure of academic lecture. The focus of the study here presented is to investigate the structure and organization of a university lecture through the introduction of new topics. One of the tools traditionally referred to as an organizer of discourse is metadiscourse (Crismore et al. 1993. Metadiscourse in persuasive writing: A study of texts written by American and Finnish university students. Written Communication, 10:39–71; Vande Kopple. 1985. Some exploratory discourse on metadiscourse. College Composition and Communication, 36(1):82–93). Although metadiscourse has been studied from a wide range of perspectives (Hyland. 2005. Metadiscourse: exploring interaction in writing. London, England: Continuum), these analyses have most of the time been conducted from a purely linguistic point of view and neither the speaker as a social actor nor metadiscourse as part of a multimodal interaction are taken into account. That being so, the aim of this study is to explore the role played by

Abstract
Extremophilic organisms demonstrate the flexibility and adaptability of basic biological processes by highlighting how cell physiology adapts to environmental extremes. Few eukaryotic extremophiles have been well studied and only a small number are amenable to laboratory cultivation and manipulation. A detailed characterization of the genome architecture of such organisms is important to illuminate how they adapt to environmental stresses. One excellent example of a fungal extremophile is the halophile Hortaea werneckii (Pezizomycotina, Dothideomycetes, Capnodiales), a yeast-like fungus able to thrive at near-saturating concentrations of sodium chloride and which is also tolerant to both UV irradiation and desiccation. Given its unique lifestyle and its remarkably recent whole genome duplication, H. werneckii provides opportunities for testing the role of genome duplications and adaptability to extreme environments. We previously assembled the genome of H. werneckii using short-read sequencing technology and found a remarkable degree of gene duplication. Technology limitations, however, precluded high-confidence annotation of the entire genome. We therefore revisited the H. wernickii genome using long-read, single-molecule sequencing and provide an improved genome assembly which, combined with transcriptome and nucleosome analysis, provides a useful resource for fungal halophile genomics. Remarkably, the ∼50 Mb H. wernickii genome contains 15,974 genes of which 95% (7608) are duplicates formed by a recent whole genome duplication (WGD), with an average of 5% protein sequence divergence between them. We found that the WGD is extraordinarily recent, and compared to Saccharomyces cerevisiae, the majority of the genome’s ohnologs have not diverged at the level of gene expression of chromatin structure.
Exploring the Impact of Cleavage and Polyadenylation Factors on Pre-mRNA Splicing Across Eukaryotes
Authors: Lepennetier Gildas , Catania Francesco 
Published: May 2017

Abstract
In human, mouse, and Drosophila, the spliceosomal complex U1 snRNP (U1) protects transcripts from premature cleavage and polyadenylation at proximal intronic polyadenylation signals (PAS). These U1-mediated effects preserve transcription integrity, and are known as telescripting. The watchtower role of U1 throughout transcription is clear. What is less clear is whether cleavage and polyadenylation factors (CPFs) are simply patrolled or if they might actively antagonize U1 recruitment. In addressing this question, we found that, in the introns of human, mouse, and Drosophila, and of 14 other eukaryotes, including multi- and single-celled species, the conserved AATAAA PAS—a major target for CPFs—is selected against. This selective pressure, approximated using DNA strand asymmetry, is detected for peripheral and internal introns alike. Surprisingly, it is more pronounced within—rather than outside—the action range of telescripting, and particularly intense in the vicinity of weak 5′ splice sites. Our study uncovers a novel feature of eukaryotic genes: that the AATAAA PAS is universally counter-selected in spliceosomal introns. This pattern implies that CPFs may attempt to access introns at any time during transcription. However, natural selection operates to minimize this access. By corroborating and extending previous work, our study further indicates that CPF access to intronic PASs might perturb the recruitment of U1 to the adjacent 5′ splice sites. These results open the possibility that CPFs may impact the splicing process across eukaryotes.

AbstractAccumulation of toxic proteins in neurons has been linked with the onset of neurodegenerative diseases, which in many cases are characterized by altered neuronal function and synapse loss. Molecular chaperones help protein folding and the resolubilization of unfolded proteins, thereby reducing the protein aggregation stress. While most of the chaperones are expressed in neurons, their functional relevance remains largely unknown. Here, using bioinformatics analysis, we identified 95 Drosophila chaperones and classified them into seven different classes. Ubiquitous actin5C-Gal4-mediated RNAi knockdown revealed that ∼50% of the chaperones are essential in Drosophila. Knocking down these genes in eyes revealed that ∼30% of the essential chaperones are crucial for eye development. Using neuron-specific knockdown, immunocytochemistry, and robust behavioral assays, we identified a new set of chaperones that play critical roles in the regulation of Drosophila NMJ structural organization. Together, our data present the first classification and comprehensive analysis of Drosophila chaperones. Our screen identified a new set of chaperones that regulate eye and NMJ morphogenesis. The outcome of the screen reported here provides a useful resource for further elucidating the role of individual chaperones in Drosophila eye morphogenesis and synaptic development.
