Published: August 2017

Aim To evaluate (1) the usefulness of thoracic ultrasound in diagnosis and staging of bronchogenic carcinoma by comparing lesion detectability between thoracic- ultrasound and computed tomography and (2) the outcome of thoracic-ultrasound-guided biopsy in diagnosing bronchogenic carcinoma. Methods We conducted a cross-sectional study on 53 patients of confirmed bronchogenic carcinoma. All patients had been investigated by thoracic-ultrasound and chest-computed tomography; data regarding the presence of mass (its size, necrosis), lymph nodes invasion, peritumoural atelectasis, consolidations, pleural effusion, chest wall invasion, and paralysis of the diaphragm were recorded. Thoracic-ultrasound-guided biopsy was done for 41 patients. Results Thoracic-ultrasound had significantly higher detection rate of peritumoural atelectasis, paralysis of the diaphragm, and supraclavicular lymph nodes invasion, while it has significantly lower detection rate of pulmonary masses and mediastinal lymph nodes invasion than computed tomography. It has nonsignificant higher detection rate of pleural effusion, consolidations, chest wall invasion and necrosis within mass than computed tomography. Thoracic-ultrasound detects static air-bronchogram and/or fluid bronchogram in 53.3% of bronchogenic carcinoma-associated consolidation. Thoracic-ultrasound-guided biopsy revealed positive yield in 78.0% (32/41) of patients. All patients with negative thoracic-ultrasound biopsy had mass size >5 cm with necrosis within the mass. Self-limited complications occurred in 26.8% after thoracic-ultrasound-guided biopsy (haemoptysis 22.0%, pneumothorax 2.4% and subcutaneous emphysema 2.4%). Conclusion Thoracic-ultrasound has a significant complementary role to computed tomography in diagnosis and staging of bronchogenic carcinoma. Thoracic-ultrasound-guided biopsy revealed good positive yield (78%), its yield was negatively affected by mass size and necrosis. It is a simple, practical and accurate procedure without significant patients’ risks.

Published: August 2017

Background: Athletic pubalgia is typically associated with male athletes participating in contact sports and less frequently with females. Endoscopic surgery may fully treat the patient with athletic pubalgia. Purpose: To perform an outcomes analysis of magnetic resonance imaging (MRI) and endoscopic surgery in female patients with athletic pubalgia. Study Design: Cohort study; Level of evidence, 3. Methods: Fifteen physically active female patients (mean age, 37 years) with athletic pubalgia were treated surgically via placement of total extraperitoneal endoscopic polypropylene mesh behind the injured groin area. The presence of preoperative bone marrow edema (BME) at the pubic symphysis seen on MRI was graded from 0 to 3 and correlated with pain scores after surgery. The outcome measures were pre- and postoperative pain scores and recovery to daily activity between 1 and 12 months after surgery. Results were compared with previously published scores from male athletes (n = 30). Results: With the exception of lower body mass index, the females with (n = 8) and without (n = 7) pubic BME had similar patient characteristics to the corresponding males. Mean inguinal pain scores (0-10) before surgical treatment were greater in females than males (during exercise, 7.8 ± 1.1 vs 6.9 ± 1.1; P = .0131). One month after surgery, mean pain scores for females were still greater compared with males (2.9 ± 1.7 vs 1.3 ± 1.6; P = .0034). Compared with female athletes with normal MRI, pubic BME was related to increased mean preoperative pain scores (8.13 ± 0.99 vs 6.43 ± 1.2; P = .0122). After 1 year, surgical outcomes were excellent or good in 47% of women. Conclusion: Endoscopic surgery was helpful in half of the females with athletic pubalgia in this study. The presence of pubic BME may predict slightly prolonged recovery from surgery.

Published: August 2017

Background Evidence continues to build suggesting that the GABAergic neurotransmitter system is altered in brains of patients with major depressive disorder. However, there is little information available related to the extent of these changes or the potential mechanisms associated with these alterations. As stress is a well-established precipitant to depressive episodes, we sought to explore the impact of chronic stress on GABAergic interneurons. Methods Using western blot analyses and quantitative real-time polymerase chain reaction, we assessed the effects of five-weeks of chronic unpredictable stress exposure on the expression of GABA-synthesizing enzymes (GAD65 and GAD67), calcium-binding proteins (calbindin, parvalbumin, and calretinin), and neuropeptides co-expressed in GABAergic neurons (somatostatin, neuropeptide Y, vasoactive intestinal peptide, and cholecystokinin) in the prefrontal cortex and hippocampus of rats. We also investigated the effects of corticosterone and dexamethasone exposure on these markers in vitro in primary cortical and hippocampal cultures. Results We found that chronic unpredictable stress induced significant reductions of GAD67 protein levels in both the prefrontal cortex and hippocampus of chronic unpredictable stress-exposed rats but did not detect changes in GAD65 protein expression. Similar protein expression changes were found in vitro in cortical neurons. In addition, our results provide clear evidence of reduced markers of interneuron population(s), namely somatostatin and neuropeptide Y, in the prefrontal cortex, suggesting these cell types may be selectively vulnerable to chronic stress. Conclusion Together, this work highlights that chronic stress induces regional and cell type-selective effects on GABAergic interneurons in rats. These findings provide additional supporting evidence that stress-induced GABA neuron dysfunction and cell vulnerability play critical roles in the pathophysiology of stress-related illnesses, including major depressive disorder.

Published: August 2017

Abstract
A new triple-electrode system was developed for the simultaneous determination of l-lactate and d-glucose by using track-etched microporous membrane electrodes, which enabled efficient electrolysis as electroactive substances passed through the electrode. The proposed biosensor was fabricated by alternate stacking of the electrodes and immobilized enzyme reactors along the flow direction of the sample solution. When the sample solution containing l-lactate and d-glucose flowed into the proposed biosensor, hydrogen peroxide was produced by each enzymatic reaction and detected individually by anodization at each detector-electrode positioned downstream of each enzyme reactor. The interfering substances, such as l-ascorbic acid and uric acid, were electrolyzed completely at the pre-reactor electrode that was positioned upstream of the enzyme reactors. As a result, the simultaneous detection of l-lactate and d-glucose was achieved with no other catalytic material such as peroxidase or an electron mediator in the presence of the interferents at physiological concentrations in human blood.
Super Partes? Assessing the Effect of Judicial Independence on Entry
Authors: Conti Raffaele , Valentini Giovanni 
Published: August 2017

Incumbents can enjoy a cost advantage vis-à-vis new entrants and so deter new firm entry by establishing and leveraging connections with the judicial system. Connected firms may in fact avoid fully complying with the costly norms implied by a law, a regulation, or a contract. At the same time, they can also credibly threaten to sue new entrants. Therefore, a change in the institutional environment that diminishes the ability of incumbent firms to establish judicial connections—i.e., an increase in judicial independence—can promote entrepreneurship. Exploiting reforms that change the way in which U.S. state judges are selected, we confirm that this is the case, and we show that this effect is more salient in states and industries where the likelihood of entering into a business dispute is higher. The paper also sheds some light on the mechanisms behind this effect. Data and the online appendix are available at https://doi.org/10.1287/mnsc.2017.2794 .

Capacity Sharing Between Competitors
Authors: Guo Liang , Wu Xiaole 
Published: August 2017

Market competition may lead to mismatch between supply and demand. That is, overpricing may give rise to underselling, and underpricing may yield stockout. Capacity sharing is a common practice to align excessive capacity with excessive demand. Yet, the strategic interaction between competition and capacity sharing has not been adequately addressed. In this paper, we investigate optimal strategies and firm profitability of capacity sharing between competing firms under both ex ante and ex post contracting, depending on whether the capacity-sharing price is determined before or after price setting in the buyer market. We show that, with symmetric capacity, committing to an overly high capacity-sharing price may not necessarily improve firm payoffs. Capacity sharing softens price competition under either contracting scheme, whereas the optimal capacity-transfer price and equilibrium profits may be nonmonotonically influenced by buyer loyalty. The equilibrium outcome under ex ante contracting is more sensitive to variations in market parameters than ex post contracting. As a result, ex ante contracting is more likely to be preferred when the endowed capacity is low or buyer loyalty is high. However, when firms’ capacity is asymmetric, capacity sharing may intensify equilibrium competition and hurt firm profitability through reversing the firms’ relative pricing aggressiveness.

Published: August 2017

Abstract
This piece is in the form of a graphic list of subconscious writings originally derived from a series of text messages that were deconstructed letter by letter and then reformed by assuming words from the displaced letters. The piece demonstrates how writing under a deliberate rule causes an uncommon textual disposition with an overall blurred meaning. The piece takes the shape of a horizontal line graph that acknowledges the ups and downs of the quotidian.
Wellness (January, 2017)
Authors: Worth Zara 
Published: August 2017

Abstract
This piece is in the form of a graphic suite of 31 digital collages for the 31 days of January, starting with ‘#wellness’ and ending with ‘#trump’. The piece is a meta-lexicon and cipher for the platform it takes as its medium. Hashtags and appropriated and subtly reworked images are collaged together, using the virtual platform they inhabit as a ground for détourned mingling. The artist plays a disassociation game with hashtags, using them as an unpredictable pathway to the next word or phrase. As the hashtags accumulate, each addition to the snaking words is combined with an image from the ‘Instaarchive’ to create new puns and misapprehensions.

A Guided Reading of Images: A Strategy to Develop Critical Thinking and Communicative Skills
Authors: Sarmiento Sierra Marisol 
Published: August 2017

This article describes the effects of a strategy aimed at helping students develop critical thinking and communicative skills by means of a program for guided reading of images using the questioning technique in an EFL context. Many teachers are not prepared for the education of critical thinkers as part of their curricular work. This is a qualitative descriptive research study carried out with third graders from a public school in Bogotá, Colombia in which field notes, artifacts, and questionnaires were used as data collection instruments. The study showed that the program activated children’s mental processes to allow them to move from basic to higher levels of critical thinking while communicating their thoughts in Spanish as well as using vocabulary in English. This strategy could be used by teachers of different disciplines.
Cross-linguistic influence in the writing of an Italian learner of English as a foreign language: An exploratory study
Authors: Chapetón Claudia Marcela 
Published: August 2017

This paper is based on the analysis of the nature of the first language influence on the written production of an Italian learner of English as a foreign language. The goal of the present exploratory study is to examine how cross-linguistic influence manifests itself at the level of syntax and lexis. Findings suggest that forms and meanings in the L2 are expressed and shaped by the learner’s knowledge and use of the foreign language as well as by the influence of the mother tongue.
A pathological example in nonlinear spectral theory

Abstract
We construct an open set

on which an eigenvalue problem for the p-Laplacian has no isolated first eigenvalue and the spectrum is not discrete. The same example shows that the usual Lusternik–Schnirelmann minimax construction does not exhaust the whole spectrum of this eigenvalue problem.

Published: August 2017

Abstract

Background:
Serum free light chain (sFLC) measurements are increasingly important in the context of screening for monoclonal gammopathies, prognostic stratification, and monitoring of therapy responses. At the same time, analytical limitations have been reported with the currently available nephelometric and turbidimetric sFLC assays. We have evaluated a new quantitative sFLC ELISA for its suitability in routine clinical use.

Methods:
Reference ranges of the Sebia FLC assay were calculated from 208 controls. Assay interference, reproducibility, lot-to-lot variability, and linearity were assessed. Method comparison to the Freelite assay (Binding Site) was conducted by retrospective analysis of 501 patient sera.

Results:
Reference ranges of the Sebia κ/λFLC-ratio were 0.37–1.44. We observed good sensitivity (1.5 mg/L) and linearity in both polyclonal and monoclonal sFLC samples and never experienced antigen excess. Sebia FLC reproducibility varied between 6.7% and 8.1% with good lot-to-lot consistency. Method comparison with Freelite showed the following correlations: κFLC R=0.94, λFLC R=0.92 and κ/λFLC-ratio R=0.96. The clinical concordance of the κ/λFLC-ratio of both methods was 94%. Significant quantitative differences were observed between both methods, mainly in sera with high FLC concentrations. The Sebia monoclonal FLC concentrations were coherent with those obtained by serum protein electrophoresis (SPE). Freelite monoclonal FLC concentrations were consistently higher, with a mean 12-fold overestimation compared to SPE.

Conclusions:
The Sebia FLC assay provides a novel platform for sensitive and accurate sFLC measurements. The Sebia FLC showed good clinical concordance with Freelite. Further studies are warranted to confirm the clinical value of this assay.
Negotiating family history: Media use among descendants of Danish Nazis
Authors: Krogsgaard Ole 
Published: August 2017

AbstractDanish descendants of former national socialists live in a society that characterizes their parents as traitors. They are therefore likely to experience a stark divergence between how the past is described in media texts and in their families. Taking media use as the starting point, this contribution explores the role Occupation-related media texts play for Nazi descendants and how they relate them to memories generated in their families. The contribution is empirically based on five semi-structured, qualitative interviews with children of former Danish Nazis. To understand the respondents’ media use, a remembered media repertoires approach is developed and employed in conjunction with a semi-narrative interview strategy. The findings suggest that respondents from families that have cultivated a memory about the Nazi past use media texts to supplement their family memory and criticize the mainstream cultural memory, whereas respondents from families where this past was a taboo avoid Occupation-related media texts but accept the cultural memory’s portrayal of national socialists.
Mediated memory making: The virtual family photograph album
Authors: Holloway Donell , Green Lelia 
Published: August 2017

AbstractDomestic photography and the family photograph album hold significance as artefacts “communicating an ideal familial image and reifying the familial bonds, and also preserving a memory of a specific time” (Sarvas and Frohlich, 2011, p. 148). However, today’s practice of domestic photography is generally relocated to social media (Sarvas and Frohlich, 2011). Photographs previously found in the family photograph album are now likely to be located on the screens of phones and tablets.Using a Domestication of Technology framework, this article discusses how families are using Facebook to create, curate, share and archive family memories. It shows how families go through the phases of appropriation, incorporation, objectification and conversion when they adopt Facebook as the family photograph album. The authors also explore ways in which virtual family photograph albums can result in parental tension around domestic tasks of sharing and archiving family memories online, along with the possible implications of creating a potentially embarrassing, unauthorized digital footprint for their children.
CFD Simulation on the Hydrodynamics in Gas-Liquid Airlift Reactor
Authors: Liew Shi Yan , Gimbun Jolius 
Published: August 2017

Abstract
Two-fluid model approach to simulate gas-liquid airlift reactors is widely implemented but have yet to reach a consensus on the closure model to account the gas-liquid interphase forces. Proper selection of a closure model is required in order to accurately capture the hydrodynamics in the complex of the two-phase system. Our work concerns the evaluation of the interfacial forces models (i. e. drag, lift and turbulent dispersion force) and their effects on local gas holdup and liquid velocity. A transient three-dimensional airlift reactor simulation was carried out using computational fluid dynamics by implementing the dispersed standard k-ε turbulence model. Four drag models governed by spherical bubble, bubble deformation and Rayleigh-Taylor were being evaluated in our work. The significance on the inclusion of the lift model on predictive accuracy on the flow field was also studied as well. Whereas, two turbulent dispersion force models were selected to evaluate on their performance in improving the predictive accuracy of the local hydrodynamics. Results showed that the drag governed by Rayleigh-Taylor which accounts the bubble swarm effect had better predictions on the gas holdup in the downcomer and improved predictions in radial gas holdup. The inclusion of the lift model improved local gas holdup predictions at higher heights of the reactor and shifted the bubble plume towards the centre region of the riser. Meanwhile, the turbulent dispersion models improved the overall results of predicted local gas holdup with closer agreement obtained when the drift velocity model was considered in the simulation. The axial liquid velocity was well predicted for all cases. The consideration of the drag, lift and turbulent dispersion forces resulted in a closer agreement with experimental data.
