Published: March 2018

BACKGROUND:
Postreperfusion syndrome (PRS) has been shown to be related to postoperative morbidity and graft failure in orthotopic liver transplantation. To date, little is known about the impact of PRS on the prevalence of postoperative acute kidney injury (AKI) and the postoperative outcomes after living donor liver transplantation (LDLT). The purpose of our study was to determine the impact of PRS on AKI and postoperative outcomes after LDLT surgery.

METHODS:
Between January 2008 and October 2015, we retrospectively collected and evaluated the records of 1865 patients who underwent LDLT surgery. We divided the patients into 2 groups according to the development of PRS: PRS group (n = 715) versus no PRS group (n = 1150). Risk factors for AKI and mortality were investigated by multivariable logistic and Cox proportional hazards regression model analysis. Propensity score (PS) analysis (PS matching and inverse probability of treatment weighting analysis) was designed to compare the outcomes between the 2 groups.

RESULTS:
The prevalence of PRS and the mortality rate were 38% and 7%, respectively. In unadjusted analyses, the PRS group showed more frequent development of AKI (P < .001), longer hospital stay (P = .010), and higher incidence of intensive care unit stay over 7 days (P < .001) than the no PRS group. After PS matching and inverse probability of treatment weighting analysis, the PRS group showed a higher prevalence of postoperative AKI (P = .023 and P = .017, respectively) and renal dysfunction 3 months after LDLT (P = .036 and P = .006, respectively), and a higher incidence of intensive care unit stay over 7 days (P = .014 and P = .032, respectively).

CONCLUSIONS:
We demonstrated that the magnitude and duration of hypotension caused by PRS is a factor contributing to the development of AKI and residual renal dysfunction 3 months after LDLT.
Robotics-inspired biology

Published: March 2018

ABSTRACTFor centuries, designers and engineers have looked to biology for inspiration. Biologically inspired robots are just one example of the application of knowledge of the natural world to engineering problems. However, recent work by biologists and interdisciplinary teams have flipped this approach, using robots and physical models to set the course for experiments on biological systems and to generate new hypotheses for biological research. We call this approach robotics-inspired biology; it involves performing experiments on robotic systems aimed at the discovery of new biological phenomena or generation of new hypotheses about how organisms function that can then be tested on living organisms. This new and exciting direction has emerged from the extensive use of physical models by biologists and is already making significant advances in the areas of biomechanics, locomotion, neuromechanics and sensorimotor control. Here, we provide an introduction and overview of robotics-inspired biology, describe two case studies and suggest several directions for the future of this exciting new research area.
The Offshoring Return Premium
Authors: Hoberg Gerard , Moon S. Katie 
Published: March 2018

We use 10-K filings to construct novel text-based measures of the extent to which U.S. firms are exposed to three offshore activities: the sale of output, purchase of input, and ownership of producing assets. Our main result is that selling output abroad is associated with higher stock returns, especially when output is sold to more central nations in the real trade network. In contrast, offshore input serves as a hedge. Our findings are consistent with the conclusion that aggregate quantity shocks are the primary source of the return premium we document in the global trade network.

The Impact of E-book Distribution on Print Sales: Analysis of a Natural Experiment
Authors: Chen Hailiang , Hu Yu Jeffrey , Smith Michael D. 
Published: March 2018

Digital distribution introduces many new strategic questions for the creative industries—notably, how the use of new digital channels will impact sales in established channels. We analyze this question in the context of e-book and hardcover sales by exploiting a natural experiment that exogenously delayed the release of a publisher’s new Kindle e-books in April and May 2010. Using new books released simultaneously in e-book and print formats in March and June 2010 as the control group, we find that delaying e-book availability results in a 43.8% decrease in e-book sales but no increase in print book sales on Amazon.com or among other online or offline retailers. We also find that the decrease in e-book sales is greater for books with less prerelease buzz. Together, we find no evidence of strong cannibalization between print books and e-books in the short term and no support for the sequential distribution of books in print versions followed by e-book versions.

Impact of Gender and Conference Size on Conference Preferences – Employing Natural Language Processing
Authors: Eckhaus Eyal , Davidovitch Nitza 
Published: March 2018

<p style="text-align:justify">This pilot study focuses on the impact of academic conferences from a gender-based perspective. What motivates faculty members to attend conferences? Which conferences do they choose? Can differences be found between men and women in their attitude to the effect of the conference and its contribution to their academic work, in light of many studies on the significance women attach to the value of family and its prioritization over their career? The study dealt with a case study of one university in Israel. Ninety four academic faculty members from a variety of departments completed a questionnaire, including 60.9% women and 39.1% men. The main finding is that, among both men and women, academic conferences are perceived as contributing to their professional development. Faculty members addressed the contribution of conferences to their professional development. Findings showed that professional focusing during conferences results in publications and develops interest in the conference – and not vice versa, i.e., it is not interest in the conference that leads to publications. It was also found that the size of the conference predicts the significance of the focus on professional aspects. From a gender perspective, women prefer small conferences. In addition, for women, although they prefer small conferences they attach significance to collaborations that lead to professional focusing on their fields of research. Women appear to bring their "family-oriented patterns" to their work, explaining their inclination to small and more intimate conferences. The research findings might have an impact on the consideration given to planning academic conferences in order to reach the academic outcomes expected by faculty members who perceive conferences as an essential platform for their professional development. </p>
Hamstring autograft size importance in anterior cruciate ligament repair surgery
Authors: Figueroa Francisco , Figueroa David , Espregueira-Mendes João 
Published: March 2018

Graft size in hamstring autograft anterior cruciate ligament (ACL) surgery is an important factor directly related to failure. Most of the evidence in the field suggests that the size of the graft in hamstring autograft ACL reconstruction matters when the surgeon is trying to avoid failures. The exact graft diameter needed to avoid failures is not absolutely clear and could depend on other factors, but newer studies suggest than even increases of 0.5 mm up to a graft size of 10 mm are beneficial for the patient. There is still no evidence to recommend the use of grafts > 10 mm. Several methods – e.g. folding the graft in more strands – that are simple and reproducible have been published lately to address the problem of having an insufficient graft size when performing an ACL reconstruction. Due to the evidence presented, we think it is necessary for the surgeon to have them in his or her arsenal before performing an ACL reconstruction. There are obviously other factors that should be considered, especially age. Therefore, a larger graft size should not be taken as the only goal in ACL reconstruction.

Through the lens of a jewellery practice: An inquiry into photographic representation within a practice-based Ph.D.
Authors: Geremia Allison 
Published: March 2018

Abstract
In the context of a practice-based Ph.D. programme, photography plays an important role within the written thesis. Starting from the recognition that both photography and jewellery can be understood as having a dual nature, in that they can both function as subject and object, this article explores how photography can change the physical object. A practitioner of photography and jewellery can create a complex inquiry when engaging with both mediums. This article considers how each medium can be considered a form of practice in its own right and how each has the ability to change presentation and viewership.
A story about a drawing
Authors: Rankovic Katarina 
Published: March 2018

Abstract
This story about a drawing narrates the inner world of the page and its populace of lines, their struggles and their peace, and how all this internal drama hangs contingently on the vast physical and historical world that it is a part of. The story is extrapolated from video essays in which I film myself hurriedly attempting to verbalize fragments of the accelerated decision-making process accentuated by my flitting wrist while drawing. Talking Drawing is a method of historical restoration taking place at the site of the moving hand that questions what its choreographic inheritance has to say about the plethora of semantic decisions explicit in the drawing.
There turned out to be very little I could glean of my hand’s wisdom; it scarcely seems attached to me, so possessed is it by the gestures of other artists, those I have never met and many of whom were dead long before I was born. But just as sagas, which through a few stories retold by narrators excavate a genealogy of Nordic heroes and outlaws, the hand that draws is the hand that lives to tell the tale of those that came before it. The singular drawing as narrative, as history, is considered here as an iteration in an evolution concerning hands, eyes and lines spanning enormous timescales of innumerable individuals. This enormity is emphasized in order to appreciate the economy of a drawing, which contains all this history effortlessly, and whose ingenuity far surpasses my imagination. The following account, both technical and narrative, attempts to locate points at which the pragmatic approach in drawing appears inseparable from semantic concern and meditates on the relationship that these decisions have with the identities of the artist, her ghosts and readers of drawings.
Major Advances and Challenges in Heterogeneous Catalysis for Environmental Applications: A Review
Authors: Wacławek Stanisław , Padil Vinod V.T. , Černík Miroslav 
Published: March 2018

AbstractHeterogeneous catalysis is one of the fastest developing branches of chemistry. Moreover, it is strongly connected to popular environment-related applications. Owing to the very fast changes in this field, for example, numerous discoveries in nanoscience and nanotechnologies, it is believed that an update of the literature on heterogeneous catalysis could be beneficial. This review not only covers the new developments of heterogeneous catalysis in environmental sciences but also touches its historical aspects. A short introduction to the mechanism of heterogeneous catalysis with a small section on advances in this field has also been elaborated. In the first part, recent innovations in the field of catalytic air, water, wastewater and soil treatment are presented, whereas in the second part, innovations in the use of heterogeneous catalysis for obtaining sustainable energy and chemicals are discussed. Catalytic processes are ubiquitous in all branches of chemistry and there are still many unsolved issues concerning them.
Disjunctive clauses with o. o ‘either. or’ in Spanish and clausal cosubordination
Authors: Conti Carmen 
Published: March 2018

AbstractThis paper examines disjunctive clauses marked witho… o‘either… or’ in Spanish with a view to demonstrating that, in contrast to conventional analyses,o… o-clauses are actually cosubordinate:o… o-clauses are [+dependent, ‒embedded], they generally share clausal operators and they often denote an episode or a sequence of events showing some sort of continuity in space as well as participants. To this end, this paper will describe subordinate and coordinate clauses in accordance with several tests and will go on to outline the properties ofo… o-clauses, focusing in particular on their similarities and differences with respect to coordinate and subordinate clauses. Finally, it will describe whyo… o-clauses would be better classified as examples of clausal cosubordination.
Minimizers in Azerbaijani from a comparative perspective
Authors: Suleymanova Venera , Hoeksema Jack 
Published: March 2018

AbstractAzerbaijani, like many other languages, has a class of negative polarity items denoting minimal measures (along dimensions such as size, length, duration, value, weight etc.), called minimizers. This paper presents an overview of this group of expressions, compares them to minimizers in the western European languages, in particular English and Dutch, identifies the various domains in which these minimizers may be used, and discusses their distribution across polarity-sensitive contexts such as negation, conditional clauses, questions, etc. The distribution we found, on the basis of both corpus data and native speaker judgments, is very similar to that of minimizers in English or Dutch, especially when differences are factored out which are due to the fact that Azerbaijani has strict negative concord, whereas English and Dutch do not. To this end, we distinguish two types of minimizers for Azerbaijani, negated minimizers preceded byheç bir‘not one’, and minimizers preceded bybironly.

Abstract

Background
The severity of polycystic ovarian syndrome (PCOS) has been clearly associated with insulin resistance, obesity and metabolic syndrome. The purpose of the present cross-sectional study is to investigate whether mild hypercholesterolemia alters the biochemical and clinical profile of PCOS patients.

Methods
Our study is based on a prospectively collected population of women of reproductive age who were diagnosed with PCOS according to the definition of the Rotterdam European Society of Human Reproduction and Embryology/American Society for Reproductive Medicine (ASRM/ESHRE) criteria. For the correlation analysis we used the non-parametric Spearman’s rank correlation coefficient. Partial correlation was also performed to control for potential confounders observed in the univariate analysis.

Results
Overall, 235 patients were included. Their mean age ranged between 14 and 45 years old and the body mass index (BMI) between 17 and 54. Women with mild hypercholesterolemia had a higher BMI and their fasting insulin was increased as well as indices of insulin resistance [Homeostatic model assessment (HOMA), quantitative insulin sensitivity check index (QUICKI), Matsuda index] compared to women with PCOS with normal cholesterol levels. Correlation statistics suggested that the effect of serum lipids on the hormonal profile of patients was weak. Both low-density lipoprotein (LDL) and high-density lipoprotein (HDL) exerted a significant mild negative correlation to glucose and insulin. However, after controlling the results for BMI and age (the two variables that were found significantly different in the univariate analysis) we observed that this effect was non-significant.

Conclusion
Mild hypercholesterolemia does not affect the hormonal profile of patients with PCOS; hence, to date, there is no evidence to suggest its treatment for the correction of menstrual and hormonal abnormalities in PCOS women.
Visceral adipose tissue in patients with severe mental illness
Authors: Kahl Kai G. , Deuschle Michael , Stubbs Brendon , Schweiger Ulrich 
Published: March 2018

Abstract

Background
Severe mental illnesses (SMIs), i.e. major depression, schizophrenia and bipolar disorder, are associated with an elevated risk for the development of type-2 diabetes mellitus and cardiovascular disorders. Several factors have been associated with increased cardiometabolic morbidity and mortality in SMI, including lifestyle factors (smoking, inactivity, unhealthy diet), endocrine and immunologic alterations; however, the underlying mechanisms remain to be fully uncovered. It is now well accepted that visceral adipose tissue (VAT) promotes the development of cardiometabolic disorders, at least in part by inflammatory and metabolic functions.

Methods
This paper reviews studies concerning VAT, with special focus on intra-abdominal and pericardial adipose tissue, in SMI.

Results
In patients with SMI, several studies have been performed concerning VAT. Most of these studies reported alterations of VAT particularly in patients with major depression and schizophrenia, independent of body weight and body mass index. Some of the studies also reported an increased cardiometabolic risk.

Conclusion
Patients with SMI are at increased risk of developing cardiometabolic disorders, and display increased amounts of VAT. As studies so far were mainly performed on patients before the onset of cardiometabolic disorders, VAT may serve as a biomarker for patients with SMI to assess cardiometabolic risks beyond established risk scores. Further, interventions aiming at reducing VAT in SMI are highly recommended in long-term multimodal treatment plans.
Obesity associated disease risk: the role of inherent differences and location of adipose depots
Authors: Hill Jessica H. , Solt Claudia , Foster Michelle T. 
Published: March 2018

Abstract
Obesity and associated metabolic co-morbidities are a worldwide public health problem. Negative health outcomes associated with obesity, however, do not arise from excessive adiposity alone. Rather, deleterious outcomes of adipose tissue accumulation are a result of how adipocytes are distributed to individual regions in the body. Due to our increased understanding of the dynamic relationship that exists between specific adipose depots and disease risk, an accurate characterization of total body adiposity as well as location is required to properly evaluate a population’s disease risk. Specifically, distinctive tissue depots within the body include the lower body, upper body and abdominal (deep and superficial) subcutaneous regions, as well as visceral (mesenteric and omental) regions. Upper body and visceral adipose tissues are highly associated with metabolic dysfunction and chronic disease development, whereas lower body gluteofemoral subcutaneous adipose tissue imparts protection against diet-induced metabolic derangement. Each adipose depot functions distinctly as an endocrine organ hence it has a different level of impact on health outcomes. Effluent from adipose tissue can modulate the functions of other tissues, whilst receiving differential communication from the rest of the body via central nervous system innervation, metabolites and other signaling molecules. More so, adipose depots contain a diverse reservoir of tissue-resident immune cells that play an integral part in both maintaining tissue homeostasis, as well as propagating metabolically-induced inflammation. Overall, the conceptualization of obesity and associated risks needs updating to reflect the complexities of obesity. We review adipose tissue characteristics that are linked to deleterious or beneficial adipose tissue distributions.
Radiant Heat Transfer in Nitrogen-Free Combustion Environments
Authors: Osama A. Marzouk 
Published: March 2018

Abstract
When mathematically calculating the radiant heat flux during combustion, the radiant property of a gaseous mixture can be approximated as a weighted sum of the radiant properties of fictitious gases to give an equivalent effect of the actual gas mixture. This concept has been in use for many years. However, it was initially tailored to product gases in air-combustion environment. With the advent and progress in nitrogen-free combustion (particularly for environmental purposes), the chemical composition of the combustion gases is highly altered and existing models should be assessed for their suitability in these new environments. We carried out this task, which was motivated by our recent modeling work that revealed that a new model should be developed for nitrogen-free combustion environments. The model proposed here has four participating gases plus one transparent gas and its performance in predicting radiant heat transfer in 3D benchmark problems is evaluated in comparison with existing models, using the discrete-ordinate method for directional radiation domain combined with the finite-volume method of the spatial domain.

Authors: Ertaş Öztürk Yasemin , Bozbulut Rukiye , Döğer Esra , Bideci Aysun , Köksal Eda 
Published: March 2018

Abstract

Background:
Childhood obesity and its complications are serious health problems and diet/lifestyle changes can be beneficial for the prevention of diseases. Adaptation of the Healthy Lifestyle-Diet (HLD) Index in accordance with the dietary guidelines for Turkey (TR) and determination of the relationship between metabolic syndrome risk factors in obese children were the aims of this study.

Methods:
This study was conducted on 164 overweight or obese children (87 male, 77 female) aged 9–13 years. For all participants, the HLD-TR Index and a 24-h dietary recall were performed and the mean adequacy ratio (MAR) was calculated. Anthropometric measurements and the body composition of the children were taken. Metabolic syndrome risk factors and insulin resistance were assessed.

Results:
The mean age of the male and female children was 11.2±1.49 and 11.0±1.40 years, respectively. The majority of the children were obese in both genders. There were no statistically significant differences in the HLD-TR scores between the genders. As the index scores increased, a decrease in the energy intake and an increase in the MAR were observed. Negative correlations between the index scores and body mass, waist circumference and body fat mass were observed. Furthermore, a one-unit increase in the index score decreases the insulin resistance risk by 0.91 times after adjustments for age and gender (odds ratio: 0.91 [0.85–0.97]).

Conclusions:
The HLD-TR Index is a valid tool that can give an idea about the quality of the diet in obese children. Furthermore, with the increase in the compliance with recommendations for diet/lifestyle changes, indicators of obesity and metabolic syndrome were decreased.
