A Case of Reversible Infantile Respiratory Chain Deficiency Presenting With Hypotonia, Hyperammonemia, and Failure to Thrive
Authors: Guerrero Jessenia C , Pedro Helio , Parisotto Sarah , Heller Debra , Baisre-de Leon Ada
Published: July 2019

Reversible infantile respiratory chain deficiency, previously termed reversible infantile cytochrome c oxidase (COX) deficiency myopathy, is a rare mitochondrial disorder that is characterized by severe hypotonia and generalized muscle weakness in infancy that is associated with lactic acidosis. Affected infants will spontaneously recover, if they survive the first months of life. Here, we present the case of a 4-week-old girl who initially presented with hyperammonemia, hypotonia, and failure to thrive, for which she was referred for genetic evaluation. After several tests, a distinct genetic syndrome could not be identified and she continued to deteriorate. A muscle biopsy was performed and demonstrated severe mitochondrial myopathy with abundant COX-negative fibers. Ultrastructural abnormalities of the mitochondria, diagnostic of mitochondrial myopathy, were identified on electron microscopy. Molecular studies revealed the classic homoplasmic disease causing mutation, m.14674 T>C in the MT-TE gene, associated with reversible COX deficiency. Although hyperammonemia is an unusual presentation for mitochondrial myopathies, specifically reversible infantile respiratory chain deficiency, it should be included in the list of possible presenting symptoms for this condition.

Published: July 2019

Third-generation sequencing using nanopores as biosensors has recently emerged as a strategy capable to overcome next-generation sequencing drawbacks and pitfalls. Assessing the quality of the data produced by nanopore sequencing platforms is essential to decide how useful these may be in making biological discoveries. Here, we briefly contextualized NanoR, a quality control method for nanopore sequencing data we developed, in the scenario of preexistent similar tools. We also illustrated 2 quality control pipelines, readily applicable to nanopore sequencing data, respectively, based on NanoR and PyPore, a second quality control method published by our group.

Sarcopenic obesity portends poor outcomes, yet it is under-recognized in practice. We collected baseline clinical data including data on body composition (total and segmental muscle mass and total body fat), grip strength, and 5-times sit-to-stand. We defined sarcopenia using cut-points for appendicular lean mass (ALM) and obesity using body-fat cut-points. A total of 599 clinic patients (78.5% female; mean age was 51.3 ± 14.2 years) had bioelectrical impedance analysis (BIA) data (83.8%). Mean body mass index (BMI) and waist circumference were 43.1 ± 8.9 kg/m2 and 132.3 ± 70.7 cm, respectively. All patients had elevated body fat. There were 284 (47.4%) individuals fulfilling criteria for ALM-defined sarcopenia. Sarcopenic obese persons had a lower BMI (38.2 ± 6.4 vs 47.6 ± 8.6; P < 0.001), fat-free mass (113.0 kg ± 16.1 vs 152.1 kg ± 29.4; P < 0.001), fat mass (48.4% ± 5.9 vs 49.5% ± 6.2; P = 0.03), and visceral adipose tissue (216.8 ± 106.3 vs 242.7 ± 133.6 cm3; P = 0.009) than those without sarcopenic obesity. Grip strength was lower in those with sarcopenic obesity (25.1 ± 8.0 vs 30.5 ± 11.3 kg; P < 0.001) and sit-to-stand times were longer (12.4 ± 4.4 vs 10.8 second ± 4.6; P = 0.03). Sarcopenic obesity was highly prevalent in a rural, tertiary care weight and wellness center.
How Can We Share Space? Ontologies of Spatial Pluralism in Lefebvre, Butler, and Massey
Authors: Pierce Joseph
Published: July 2019

This article compares three arguments about how space might be shared: Lefebvre’s articulation of a shared right to urban space, Judith Butler’s argument for an ethical obligation to plurally cohabitat space, and Massey’s conceptualization of space and place as radically plural. Each theorist articulates a model of how to share space; this sharing is key to how each theorist imagines possibilities for justice. Rigorous reading of these different ways of imagining sharing space illustrates how difficult sharing space justly may be. The article synthesizes these three views by privileging a Masseyan perspective on plurality. It proposes a model for sharing space that is rooted in a tension between the physical limits to co-occupation, on one hand, and the possibility of agreement about use of space, on the other. The article closes with a brief discussion of the limits of spatial justice.
Queer postmemory
Authors: Çalışkan Dilara
Published: July 2019

Drawing on 10 years of activism in Turkey’s trans movement and seven months of fieldwork in Istanbul on mutually formed mother and daughter relationship among trans women, this article looks at alternative understandings of ‘inter-generational’ transmission of memory. How can we engage alternative family making processes and non-normative formations of time with memory transmission rather than merely identify ‘inter-generational’ memory in advance with pre-established non-normative systems? Or can we talk about ‘inter-generational’ memories without knowing what ‘generation’ really means? Inspired by these questions, Marianne Hirsch’s work on postmemory and narratives of self-identified trans mothers and daughters, in this article the author discusses the conceptualization of ‘queer postmemory’ in order to think critically on unmarked temporal and familial dimensions in the study of collective and personal memory. While refusing to position memory as an outcome of predetermined temporal frameworks within normative understandings of family, the author looks at strangely remembered things through glimpses of other types of time, other types of relationalities and other types of inheritability.
Active thrust fluid-film bearings: Theoretical and experimental studies
Authors: Babin Alexander , Kornaev Alexey , Rodichev Alexey , Savin Leonid
Published: July 2019

Research in the field of active fluid-film bearing has been recently getting more and more attention, integration of control systems becoming one of the most promising means of enhancement of rotor-bearing nodes' characteristics. It has been determined that the vast majority of papers published on active fluid-film bearing only consider radial bearings, and very few focus on thrust bearings. This lack of attention along with the obvious necessity to fill the said gap has triggered the present research. In cases of rotor machines that experience extensive axial loading due to various reasons, e.g. various turbine engines (aero and spacecraft) and hydraulic pumps (crude oil extraction facilities), such research could prove the feasibility of application of a control system to significantly increase the performance of the whole machine. Moreover, extensive wear during start up and shut down could be eliminated by means of rotor position control, thus life time of a rotor-bearing system could be significantly increased. The present paper features a complex mathematical model of an active thrust fluid-film bearing with a central feeding orifice, a developed test rig designed to verify the presented mathematical model allowing a series of numerical tests to be carried out. Numerical studies focus on the hypothesis of a possibility to use active control in thrust bearings to decrease power loss due to friction and extensive axial vibrations by means of identification of an energy efficient area of axial gaps based on the lubrication regime and its maintenance by means of application of controlled lubrication principles.

Published: July 2019

The subject of nanofriction having its origins in the late 19th century has slowly but surely started picking up lately. With rapid advancements in science and technology throughout the last century, understanding nanofriction has been gaining prominence. In this context, and in the current 21st century of nanotechnology, it is expected that nanofriction will play a predominant role, as we try moving forward to solve the most pressing medical and biological problems with the usage of nanobots. It is important to understand the challenges we have to encounter in order to solve these problems for the benefit of the human race. The availability of high speed computers and smart algorithms has made it possible to investigate the problems (as outlined above and many more) without compromising on the complexities involved. The focus of the present review is to bring together major theoretical/mathematical models and computational approaches to study friction at nanoscale. The role of adhesion in the estimation of force of friction at nanoscale has also been clearly outlined. A critical discussion on the significance of single and multiple asperity models towards estimating friction at nanoscale has also been provided. At the end, a short description on scanning probe microscopy in estimating nanofriction has been provided for the completeness of the review.
Running-in effects on friction of journal bearings under slow sliding speeds
Authors: Linjamaa A , Lehtovaara A , Kallio M , Léger A
Published: July 2019

Hydrodynamic thrust and journal bearings are facing challenges in modern heavy-duty machinery where full film lubrication cannot always be achieved or sustained. This is due to reasons such as start–stop operation, increased power density and the use of thinner lubricants. Although this leads to increased overall efficiency, bearings are operating more often under mixed lubrication conditions. This is why the running-in behavior of the bearing material is important. In this study, running-in behavior of traditional leaded tin bronze and its environmentally sustainable alternative, bimetal bismuth, was studied. Experimental friction tests were performed with journal bearings under full film and mixed lubrication conditions in order to find the Stribeck curves. The results are analyzed using frictional energy, and friction coefficient values based on continuous friction monitoring. Remarkable reduction of friction was observed with both bearing materials due to running-in.
Carving a contemporary replica of the 1769 ‘Joseph Banks’ panel using pre-steel tools: reviving a traditional Māori carving technique
Authors: Green (Ngāti Porou, Ngāti Wairere) Wiremu T.
Published: July 2019

In this article, the author explores previously lost techniques and practices associated with reproducing a New Zealand Māori wood carving of a poupou (panel) that was collected by Joseph Banks in October 1769 from a partly-constructed house on Pourewa Island, Tolaga Bay (Ūawa), North Island. The original poupou, a rare Māori artefact that pre-dates European influence, is curated today in the University Museum, Tübingen. A conference in Oslo, Norway, in 2014, provided the author, a tohunga whakairo (master carver), with the opportunity to demonstrate the use of Māori pre-steel tools, notably pounamu (greenstone) and argillite toki (adzes), greenstone and toroa whao (albatross bone chisels), and hardwood tā (carving mallets). The unique, historically inspired and practice-led empirical research undertaken in carving the poupou has helped to recover previously lost indigenous wood-carving knowledge. The replica poupou, carved in totara ( Podocarpus totara) and coated in kokowai (ochre), was subsequently completed at, and donated to, the Captain Cook Birthplace Museum in Middlesbrough, UK. The empirical approach to this research required detailed analysis as well as experimental archaeology and ethnography. The carving of the poupou honours the legacy of one of the most famed Māori carving centres and traditional higher schools of learning of pre-European times, namely Te Rāwheoro.
The performance of power and citizenship: David Cameron meets the people
Authors: Lunt Peter
Published: July 2019

How do citizens respond to and engage with the performance of political power in the context of mainstream media? Through an analysis of two television programmes aired during the UK Brexit referendum campaign of 2016, a picture emerges of citizenship as the performative disruption of the performance of power. In the programmes the then UK prime minister, David Cameron, met members of the public for a mediated discussion of key issues in the Brexit referendum. Their interactions are analysed here as a confrontation between the performance of citizenship and power reflecting activist modalities of disruptive citizenship played out in the television studio. The article ends with reflections on questions about political agency as individualistic forms of disruptive political autonomy.
Provocative engagement: Documentary audiences and performances in The Act of Killing and The Look of Silence
Authors: Hill Annette , Askanius Tina , Kondo Koko , Luis Urueta Jose
Published: July 2019

Through an analysis of The Act of Killing (2012) and The Look of Silence (2014), this article explores the idea of provocative engagement as a way of extending our understanding of the affective dimensions of documentary and its role in civic engagement. The study draws on qualitative research, based on interviews with the filmmaker, and interviews with 52 viewers in Denmark, Sweden, Japan and Colombia. This data is used to explore the idea of subjectivity in documentary through the performance of memory, power and impunity in both films concerning the perpetrators and victims of the Indonesian genocide of 1965. Overall, our analysis highlights how performance documentary challenges the affective relationships between filmmakers and their audiences, and in this particular case we see a type of raw, provocative engagement with the act of documenting genocide, the act of watching, and what this means to people in the context of their political and lived realities.
Performing civic cultures: Participatory public art and its publics
Authors: Iannelli Laura , Marelli Carolina M
Published: July 2019

This research investigated the performances of participatory public art as ways of taking political agency in contemporary democracy. We considered these ‘maximalist’ forms of participation – ‘multi-sited’, as the language of democratic theory suggests, in both the political sphere of art and the formal arena of politics – as ways of doing, acting, and performing citizenship in democratic societies. Drawing upon the ‘cultural turn’ in citizenship studies, we assumed civic cultures as central variables to explain these forms of political agency. Referring to media audience research, we adopted an analytical framework to explore the artists’ civic cultures that are in action in public urban spaces. The analysis focused on performances of citizenship developed in Sardinia (Italy). The research shed light on the artists’ knowledge and values, the multiple layers of audience participation envisaged in their practices of communication, their (dis)trust towards institutions and non-elite actors in civil society, and the civic identities they perform in contemporary societies.
From the Politics of Bureaucracy to the politics of representative bureaucracy
Authors: Schröter Eckhard
Published: July 2019

The Politics of Bureaucracy provides an important impetus for the research of representative bureaucracy and at the same time serves as an analytical frame for a research agenda on representativeness in the public sector. The major impetus comes from one of the book’s core messages that public administration is tightly interwoven with politics and society. As a reform paradigm, representative bureaucracy aims for a public sector workforce that mirrors the social composition of the society it is supposed to serve. If successful, this measure is expected to improve organisational performance, relations with social groups and also overall political legitimacy. However, representativeness is no panacea to treat all problems of diverse societies and non-responsive bureaucracies. Rather, potential benefits have to be discounted against likely pitfalls and extra costs incurred through the pursuit of representativeness. What is more, the inherent tensions with competing reform paradigms have to be taken into account.
Seismic energy response analysis of equipment-structure system via real-time dynamic substructuring shaking table testing
Authors: Bi Jihong , Luo Lanfang , Jiang Nan
Published: July 2019

Dynamic equations are presented that have been deduced for a real-time dynamic substructuring shaking table test of an equipment-structure system, based on the branch mode substructure method. The equipment is adopted as the experimental substructure, which is loaded by the shaking table, while the structure is adopted as the numerical substructure. Real-time data communication occurs between the two substructures during the test. A real-time seismic energy calculation method was proposed for the calculation of energy responses, both in the experimental substructure and the numerical substructure. Taking a representative four-story steel frame/equipment model, real-time dynamic substructuring shaking table tests and overall model tests were executed. The proposed real-time dynamic substructuring shaking table testing method was verified by comparing the test results with shaking table test results for the overall model. The energy responses of each component in the equipment-structure system, using different connection types, also were studied. Changes in the connection types can lead to changes in the energy responses of the equipment-structure system, especially with respect to the equipment. The choice of the connection for the equipment-structure coupled system should take into account the operational performance objective of the equipment.
A numerical–experimental assessment of wall impingement models for spark-ignition direct-injection engines
Authors: Grover Ronald O , Fansler Todd D , Lippert Andreas , Drake Michael C , Assanis Dennis N
Published: July 2019

Liquid wall impingement in direct-injection engines can cause soot and hydrocarbon emissions as well as reduced combustion efficiency. This study focuses on detailed evaluations of numerical droplet impingement criteria that govern the onset of splash. The five selected splash criteria, which all extrapolate from single-droplet impacts to full sprays, are representative of those currently in use for spark-ignition direct-injection engines. The computations examined the sensitivity of impinging spray simulations to the splash criteria for a high-pressure, direct-injection swirl spray under atmospheric conditions impinging at a 45° angle onto a flat plate. The numerical results were compared to an unusually extensive set of experimental data: Mie scattering and light transmission imaging, plus quantitative refractive index matching measurements of the fuel film area and thickness, and phase Doppler interferometry measurements of droplet size and velocity near the plate. Good qualitative and at least fair quantitative agreement was obtained for the global spray impingement and wall film formation, especially for single-drop criteria that include the effect of viscosity. The film area and shape were insensitive to the splash criteria, illustrating the importance of film thickness measurements for validating simulations. The results also revealed the sensitivity of impingement calculations to droplet arrival frequency when that is taken into account. In general, the comparisons indicated the need to capture the effect of multiple droplets impinging on the wall at irregular frequencies in the criterion, as well as other important physics of the droplet–wall interaction that may mask the true effect of the impingement criterion.
Aurora musis amica: Metaphoric conceptualization of depression in online visual representations
Authors: Poppi Fabio Indìo Massimo , Kravanja Peter
Published: July 2019

In this article, the authors analyse a selection of 30 online visual artworks in order to identify conceptual metaphors related to the target domain of DEPRESSION. While a lot of research has identified these metaphors in textual and verbal modes, they aim to understand which conceptualizations can be identified in visual and pictorial representations. Based on the analysis of their corpus of examples, they suggest that, while some visual/pictorial conceptualizations of DEPRESSION reflect research that has been carried out on the linguistic and textual levels (standard metaphors), other conceptualizations appear in order to create novel and diverse metaphors (creative metaphors). This contribution reflects the importance of analysing the role of metaphorization beyond the verbal and textual dimensions, as a large number of artworks are based on metaphors that exist on the visual level.
A qualitative systematic review of experiences of persons with dementia regarding transition to long-term care
Authors: Young Jessica A , Lind Christopher , Orange JB
Published: July 2019

Introduction

The current qualitative systematic review identified and examined critically the literature on how persons with dementia experience transitions to long-term care. Results are intended to help develop guidelines for future care and research.

Method

A search was conducted of OvidSP, SCOPUS, Web of Science, ProQuest, PsycINFO, CINAHL, AgeLine and Informit databases. In total, 4705 articles were reviewed (published 1954–2018). A textual narrative approach was used to synthesise the findings of the included articles.

Results

Seven articles met inclusion criteria (five using data collected from interviews with persons with dementia and two using reports from a proxy). Overall, the findings showed that transition to long-term care possesses varied meanings for persons with dementia, is often not the decision of the persons with dementia, and is a process throughout which social connections remain important.

Discussion

Accounts of the experiences of persons with dementia regarding transitions from community to long-term care show that they and their families should be supported: with respect to their individual contexts, to share the positives and negatives of the transition experiences, to make decisions together, and to maintain old and establish new social connections.
Exposing the mechanisms underlying successful animal-assisted interventions for people with dementia: A realistic evaluation of the Dementia Dog Project
Authors: Ritchie Louise , Quinn Samuel , Tolson Debbie , Jenkins Nick , Sharp Barbara
Published: July 2019

There is increasing recognition of animal-assisted interventions as a promising area of practice within health and social care for people living with dementia. However, much of the research focuses on benefits for those living in care homes and not in their own homes. The Dementia Dog Project is an innovative project that aims to support people with dementia to engage with dogs and to promote the use of dogs in dementia care in the community. The pilot project introduced a dementia assistance dog to four couples where one person had a diagnosis of dementia. The aim of this paper is to explore the mechanisms that can successfully expose the benefits of integrating dogs into dementia care by drawing on the findings of a realistic evaluation of the pilot phase of the Dementia Dog Project (2013–2015). A realistic evaluation, with its focus on context, mechanisms and outcomes illuminates why an approach may work in some situations but not in others. This makes it especially appropriate to the unique, complex experience of living with dementia and the early development stage of the programme. The analysis triangulated data from a range of primary and secondary sources including interviews with the project team, case reports, team meeting notes and transcripts of interviews with participants. The findings identified three mechanisms that help to unlock the most positive outcomes for both the participants and the dogs. These were (1) the human–animal bond, (2) relationship dynamics and (3) responsibility of caring. The findings presented within this paper provide essential information to inform and advance the planning for the use of assistance dogs for people with dementia.
Practicing identity in emergent firms: How practices shape founders’ organizational identity claims
Authors: Oliver David , Vough Heather C
Published: July 2019

Establishing a new firm presents a variety of challenges to organizational founders. An important concern is the development of a set of clear and coherent organizational identity claims that can inform future strategic decision-making. While practices have been identified as important resources that individuals draw on during organizational identity change and formation, their role in initiating shifts in organizational identity claims has not been examined. In this longitudinal study of seven de novo organizations, we develop a process model showing how practices engaged in by founders when establishing their firms cue sensemaking about the organization’s identity by identifying identity voids, generating identity insights through interactions with outsiders, and identifying identity discrepancies through interactions with insiders. Founders interpret these sensemaking triggers as either opportunities or threats to their identity aspirations for their firms, leading to organizational identity work that generates new identity claims. We discuss implications of our model for scholars of organizational identity emergence and practice, as well as for founders of new organizations.

Authors: Melike Gungor , Calisir Mehmet D , Akgul Yasin , Selcuk Sule , Ali Demir , Kilic Ali
Published: July 2019

In this study, polyvinylpyrrolidone-based nanofibrous air filter media were produced via centrifugal spinning and subsequently stabilized by thermal cross-linking process. Samples were produced using solutions with three different polymer concentrations (5, 10 and 20 wt.%) and three different rotational speeds (4000, 6000 and 8000 r/min). After obtaining the optimum web structure with the lowest average fiber diameter and the most uniform distribution, the webs were later thermally cross-linked in order to stabilize polyvinylpyrrolidone against the degradative effects of water. In addition, the webs were subjected to dissolvability tests to see the efficacy of cross-linking treatment. Morphological, structural and chemical characterizations of the polyvinylpyrrolidone webs were performed by SEM, XRD and FTIR, respectively. Finally, filter efficiency and pressure drop were measured to assess filter performance. The results have shown that the lowest average fiber diameter is obtained at the highest rotational speeds. Subsequent thermal cross-linking treatment has been found to prevent fibers from dissolving in water. The produced water-resistant, environmentally friendly polyvinylpyrrolidone nanofibrous filter media has had a satisfactory filtration performance with a high filter efficiency of 99.995% and a high quality factor of 0.39 mm H2O−1.

Published: July 2019

Background: Hand and distal forearm allotransplantation has advanced over the last 20 years from experimental to a viable treatment option for bilateral upper extremity amputation. Despite widespread growth of this field, there are few technical reports that elaborate the details of donor arm procurement. This article details a technique for rapid donor procurement through the elbow for mid to distal forearm-level hand allograft procurement. Methods: Nine arm procurements were performed on deceased tissue-only donors provided by the local organ procurement organization, including two bilateral and five unilateral cases. Technique highlights include using a fishmouth incision through the lateral and medical epicondyles, identification of the neurovascular structures, and disarticulating the elbow joint. Results: Procuring through the elbow provides straightforward anatomy, bypasses the need to cut through bone, and allows tissue allotransplantation teams to achieve procurement, flushing, and packaging within 20 minutes. Conclusions: Procurement through the elbow is a simple procedure that streamlines the process for multi-organ donors by minimizing the time needed for hand allograft procurement. Team coordination and surgical rehearsals are essential for successful hand and upper extremity procurement and allotransplantation.

Published: July 2019

Background: Professional baseball players are at risk of acute and chronic injuries to their upper extremities. Methods: Major League Baseball’s Health and Injury Tracking System, a prospective injury surveillance system, was used to identify and characterize all hand and wrist injuries sustained by all Major League Baseball (MLB) and Minor League Baseball (MiLB) players during the pre-, regular, and postseason throughout 2011-2016. Injuries were included if they resulted in at least 1 day out of play and were sustained during standard baseball activities. Days missed were defined as the time between injury and the first time in which a player was cleared to return to play. Results: During the study period, there were 4478 hand and 1748 wrist injuries throughout MLB and MiLB, which resulted in a total of 105 246 days out of play. This was equivalent to the length of 575 individual MLB player seasons, and the mean days missed per injury was 17 days. Most injuries were traumatic in nature, with 43% (n = 2672) of players injured after being hit by a baseball that mainly occurred during batting (n = 2521; 40%). Injuries that most frequently required surgical intervention were hook of hamate fractures (72%) and scaphoid fractures (60%). Conclusions: Understanding the epidemiology and impact of hand and wrist injuries in MLB and MiLB players may lead to improved management of these injuries and reduce time away from play. Most importantly, preventive measures and/or enhanced protective gear may be developed to minimize these types of injuries in MLB and MiLB.
Options to achieve proximal sealing zone during endovascular repair of abdominal aortic aneurysm and correlated classification
Authors: Mialhe Claude , Lareyre Fabien , Raffort Juliette
Published: July 2019

Since its first development, endovascular aortic aneurysmal repair (EVAR) has largely evolved, and several types of endografts are currently available including bifurcated grafts with supra or infra-renal fixation, fenestrated (FEVAR). Technical advances have led to propose EVAR in patients with challenging anatomy and the indications for using endografts mainly depend on patients’ vascular anatomical characteristics and on the instructions for use. Even if the minimal requirements for standard commercially available endografts have been defined, there is a lack of consensus to help surgeons to choose the most appropriate approach. Here, we propose a four-class abdominal aortic aneurysm (AAA) categorization based on the morphology and the length of the necks considered as landing zones as well as markers of potential evolution of the AAA. This pragmatic classification may help to clarify the decision-making process for selecting the most appropriate endovascular device to treat AAA in accordance with the anatomy and the foreseeable evolution and delayed complication risk to anticipate vascular outcome.
Joint attention facilitates observed gaze direction discrimination
Authors: Edwards S Gareth , Seibert Nathalie , Bayliss Andrew P
Published: July 2019

Efficiently judging where someone else is looking is important for social interactions, allowing us a window into their mental state by establishing joint attention. Previous work has shown that judging the gaze direction of a non-foveally presented face is facilitated when the eyes of that face are directed towards the centre of the scene. This finding has been interpreted as an example of the human bias for misattributing observed ambiguous gaze signals as self-directed eye-contact. To test this interpretation against an alternative hypothesis that the facilitation is instead driven by the establishment of joint attention, we conducted two experiments in which we varied the participants’ fixation location. In both experiments, we replicated the previous finding of facilitated gaze discrimination when the participants fixated centrally. However, this facilitation was abolished when participants fixated peripheral fixation crosses (Experiment 1) and reversed when participants fixated peripheral images of real-world objects (Experiment 2). Based on these data, we propose that the facilitation effect is consistent with the interpretation that gaze discrimination is facilitated when joint attention is established. This finding therefore extends previous work showing that engaging in joint attention facilitates a range of social cognitive processes.
Detection of the palmaris longus tendon: physical examination versus sonography
Authors: Holzgrefe Russell E. , Anastasio Albert T. , Farley Kevin X. , Daly Charles A. , Mason Amadeus R. , Gottschalk Michael B.
Published: July 2019

This study investigated the sensitivity, specificity, and accuracy of physical examination compared with high resolution sonography for the detection of the palmaris longus tendon in 136 wrists. The incidence of tendon absence was 10% by sonography and 14% by physical examination. The sensitivity of the physical examination was 94% and the specificity 86% compared with sonography as the reference standard. Accurate identification of the palmaris longus tendon through physical examination was not influenced by body mass index or wrist circumference. Upon review of the sonography images, none of the palmaris longus tendons missed on physical examination were considered to be adequate for grafting based on expert opinion. While physical exam was 93% accurate for detection of the palmaris longus tendon compared with ultrasound, our study suggests that it is sufficient for detection of those tendons that can be used as donors clinically.
Comparison of high-impact load-absorbing property of natural turf for professional use with various types of natural and artificial turfs in football
Authors: Nunome Hiroyuki , Inoue Koichiro , Ball Kevin , Sano Shinya , Ikegami Yasuo
Published: July 2019

The present study aimed to illustrate load stress-strain properties of various types of natural and artificial turfs. A modified high-loading test rig was used to measure shock absorbency and concurrent deformation of these surfaces in situ to calculate quasi stress-strain curves. A natural turf professionally maintained for top professional league soccer matches (N-stadium) was used as the reference surface. Other surfaces included two natural turfs without professional maintenance (one with and one without polyethylene pile reinforcement), four new artificial turfs (sand infill only, rubber infill only, both sand and rubber, and thermoplastic elastomer infill), and one aged artificial turf (8 years old with sand/rubber infill). All artificial turfs failed to mimic two properties of N-stadium, plastic deformation, and hysteresis profile, suggesting N-stadium has more energy absorbable properties than those of artificial turfs. The aged artificial turf with conventional infill was substantially stiffer than the new artificial turf with the same infill, indicating age affects the stiffness of these surfaces. Also, distinctive differences were detected between N-stadium and other natural turfs, suggesting factors such as daily maintenance work are very influential on their quasi stress-strain properties. Interestingly, no difference in the quasi stress-strain curve existed between the natural turf with and without polyethylene pile reinforcement. While artificial surfaces are improving, there is still a difference in properties between these surfaces and natural turf pitches.
Influence of different playing surfaces on bone mass accretion in male adolescent football players: A one-season study

Published: July 2019

There are different surfaces on which football is played, but their influence on bone mass accretion still remains unknown. The aims of this study were to compare bone mass accretion between football players and controls, and evaluate the influence of two different playing surfaces on bone accretion. A total of 27 male football players (13.2 ± 0.5 years) and 15 controls (12.6 ± 1.1 years) participated in this study. Football players were classified into two groups according to the surface they trained on: 14 on third-generation artificial turf with elastic layer and 13 on third-generation artificial turf without elastic layer. Bone mineral content and areal bone mineral density were measured using dual-energy X-ray absorptiometry. Bone mineral apparent density variables were calculated. Bone geometry and strength of the non-dominant tibia were assessed with peripheral quantitative computed tomography. For both football players and controls, bone variables measured at subtotal body, lumbar spine, legs and tibia ( p < 0.05) significantly increased. Based on the time spent practicing football, the increase in areal bone mineral density for the legs ( p < 0.05) was higher in football players than controls. Moreover, lumbar spine bone mineral apparent density increased more in third-generation artificial turf without elastic layer players in comparison with third-generation artificial turf with elastic layer players ( p < 0.05). Playing football on third-generation artificial turf with elastic layer and third-generation artificial turf without elastic layer seems to positively affect bone mass during growth. After playing for one season on these playing surfaces, football practice on third-generation artificial turf without elastic layer with the lower shock absorption seems to have produced the highest increment in areal bone mineral density at lumbar spine. Thus, football practice on surfaces with lower shock absorption could provide an extra benefit on bone health.
Saving the Nation by Sacrificing Your Life: Authoritarianism and Chiang Kai-shek's War for the Retaking of China
Authors: Cheng Isabelle
Published: July 2019

This article examines the role assigned to citizens by the ideology of authoritarianism in the relationship between Chiang Kai-shek's war to retake mainland China and the wartime regime constructed for fighting that war. Viewing Chiang's ambition of retaking China by force as an anti-communist nationalist war, this paper considers this prolonged civil war as Chiang's attempt at restoring the impaired sovereignty of the Republic of China. Adopting the concept of “necropolitics,” this paper argues that what underlay the planning for war was the manipulation of the life and death of the citizenry and a distinction drawn between the Chinese nation to be saved and the condemned communist Other. This manipulation and demarcation was institutionally enforced by an authoritarian government that violated citizens' human rights for the sake of winning the nationalist war.
The Wartime Regime and the Development of Public Diet in Taiwan (1947–1950s)
Authors: Tseng Pin-Tsang
Published: July 2019

The Nationalist Party retreated to Taiwan in 1949 after its defeat in the Chinese Civil War. Faced with a population explosion, economic recession, and a serious shortage of resources, the Nationalist government retained the “wartime regime” instituted during the civil war, while strengthening control of key foods – which significantly affected people's daily life, and notably diet. This article argues that the purpose of implementing the wartime regime was not only to stabilise livelihoods, particularly to secure basic living conditions for a large number of soldiers and government employees; it also helped the Nationalist Party consolidate its authoritarian rule and establish a firm grip on national resources, facilitating national defence and economic development. The stringent control measures of the wartime regime caused, however, a gross imbalance between staple and subsidiary foods in the diet of local people, leading to consumption of excessive amounts of starchy staple foods and widening the gap between the diets of farmers and non-farmers.
Authoritarianism in the Living Room: Everyday Disciplines, Senses, and Morality in Taiwan's Military Villages
Authors: Tamburo Elisa
Published: July 2019

With the nationalist government – Kuomintang (KMT) –retreating from mainland China in 1949, some 600,000 military personnel relocated to Taiwan. The military seized former Japanese colonial properties and built its own settlements, establishing temporary military dependents' villages called juancun ([Formula: see text]). When the prospect of counter-attacking the mainland vanished, the KMT had to face the reality of settling permanently in Taiwan. How, then, did the KMT's authoritarian power enter the everyday lives of its own support group? In this article I will focus on the coercive elements of KMT authoritarianism, which permeated these military villages in Taiwan. I will look at the coercive mechanisms through the analytical lens of Foucauldian discipline. I argue that disciplinary techniques such as surveillance, disciplining of the body and the senses, as well as the creation of morality regimes played an important role in the co-optation of village residents into KMT authoritarianism by normalising and naturalising it.
Women's Labour, Kinship, and Economic Changes in Jinmen in the Era of Authoritarian Rule
Authors: Chiu Hsiao-Chiao
Published: July 2019

This article uses the life stories of three women in Jinmen to demonstrate women's economic agency in bettering the livelihood of their families in circumstances largely shaped by Cold War geopolitics and the authoritarian state's military strategies. It argues that women's devotion of their labour and earnings to their families was part of the reproductive processes of the kinship system, but also important to their building of social reputation and emotional ties with their loved ones. Moreover, the state's campaign to protect traditional Chinese culture, framed within bipolar politics, supported the ideological reproduction of women's primary roles being in the domestic sphere. While the lives of Jinmen civilians were significantly distorted in the Cold War era, their experiences of economic improvement and a certain stability in their ways of life – revolving around kinship – account for the ambivalence they now feel towards the period of authoritarian rule.

Five new ent-atisene diterpene glycosides (1-5) have been isolated from Stevia rebaudiana Bertoni. This adds to a list of only 2 new ent-atisene diterpene glycosides isolated previously from S. rebaudiana. Diterpene glycosides isolated from S. rebaudiana, such as the rebaudiosides, are typically associated with the ent-kaurene core and glycosylation at the C-13 and C-19 positions. Extensive application of nuclear magnetic resonance spectroscopy techniques (1H, 13C, 1D-TOCSY, COSY, HSQC-DEPT, HMBC, and ROESY) as well as high-resolution mass spectrometry demonstrated that the ent-atisenes 1 to 5 had glycosylation patterns identical to rebaudiosides J, N, O, K, and T, respectively. We have named these compounds stevatisene J, N, O, K, and T, respectively.

The glycosylation of piceid and resveratroloside was investigated using glucosyltransferase from Phytolacca americana expressed in Escherichia coli. The enzyme glucosylated piceid at its 5- and 4′-positions to give resveratrol 3,5-diglucoside and resveratrol 3,4′-diglucoside, respectively. Resveratroloside was glucosylated to resveratrol 3,4′-diglucoside by the enzyme.

Published: July 2019

The aim of the present study was to evaluate the hypolipidemic effect of Trixis angustifolia aqueous extract (TxAE) on Triton WR-1339- and high-fat diet-induced hyperlipidemic mice. In the Triton model, treatment with TxAE at 100 and 200 mg/kg body weight produced a significant decrease in triglycerides and very low-density lipoprotein levels and a significant increase in high-density lipoprotein (HDL). Similarly, administration of TxAE along with the high-fat diet induced a significant decrease in serum total cholesterol, low-density lipoproteins, and increase in HDL. In addition, a phytochemical study of TxAE led to the isolation of 2 previously described compounds: pebrellin and xanthomicrol. This is the first time that these compounds have been identified in a plant extract with hypolipidemic effect. The results suggest the possible therapeutic potential of TxAE as a hypolipidemic agent supporting the usage of T. angustifolia as a traditional medicine.

Background

Sinonasal inverted papilloma (IP) is a rare tumor of nasal cavity and paranasal sinuses. Its etiology and factors associated with tumor progression remains unclear. Forkhead Box M1 (FoxM1) has also been suggested to serve as an oncogene due to its pivotal roles in cell proliferation and cell cycle regulation. The aim of this study was to characterize the expression pattern of FoxM1 in IP and IP with associated squamous cell carcinoma (IPwSCC).

Methods

The study included 8 subjects with IPwSCC, 17 subjects with sinonasal IP, and 8 normal uncinate tissue (UT) mucosa. Real-time polymerase chain reaction (PCR) and immunohistochemistry were used to assess the expression and distribution of FoxM1, polo-like kinase 1 (PLK1), cyclin B1, and cyclin D1 in IP tissues and normal control. The expression of FoxM1, PLK1, cyclin B1, and cyclin D1 in IPwSCC was evaluated using immunohistochemistry.

Results

The messenger RNA (mRNA) expression of FoxM1, PLK1, cyclin B1, and cyclin D1 was significantly upregulated in IP tissues versus normal UT by real-time PCR (all P values < .05). Using immunohistochemistry, the expression of FoxM1 was observed in the tumor cells of sinonasal IP and IPwSCC, but scarce positive cells in normal UT mucosa. The percentage of positive FoxM1-staining cells was statistically higher in IPwSCC than IP and normal UT mucosa (both P < .05). Both mRNA and protein expression of FoxM1 in IP with or without associated squamous cell carcinoma was correlated with tumor histological grades (both P < .05).

Conclusion

FoxM1, a proliferation specific transcription factor, was overexpressed in sinonasal IP and IPwSCC. FoxM1 might be a key molecule associated with growth of IP and malignant transformation of IP into IPwSCC.
