Published: July 2017

Background Material decomposition of dual-energy computed tomography (DECT) enables subtraction of calcified plaque. Purpose To evaluate the accuracy of lumen area measurement in calcified plaque by subtraction of DECT and to determine the effect of contrast material concentration, lumen diameter, density, and thickness of calcified plaque for the measurement. Material and Methods Vessel phantoms were made with six lumen diameters (5.7, 4.9, 3.9, 3.0, 1.9, and 1.3 mm) and six types of calcified plaques with three densities and two thicknesses were attached. CT scans were performed with three contrast material concentrations (62, 111, and 170 mg iodine/mL). Lumen area discrepancy (AD) was calculated by subtracting the measured lumen area from a reference value. The lumen area underestimation percentage (AU), defined as (AD/reference value) × 100, was calculated. General linear model analysis was used to test the effect of variables for log-transformed AU (ln_AU). Results The AD and AU was calculated to be 6.1 ± 4.8 mm2 and 69.8 ± 29.4%, respectively. Ln_AU was significantly affected by contrast material concentration ( P < 0.001), calcium density ( P = 0.001), plaque thickness ( P = 0.010), and lumen diameter ( P < 0.001). Ln_AU was significantly higher in 62 mg iodine/mL than in 111 or 170 mg iodine/mL ( P < 0.001 for both). Ln_AU was significantly lower at a lumen diameter of 5.7 mm than 3.9 mm ( P = 0.001) or 3.0 ( P < 0.001). Conclusion Calcified plaque subtraction in DECT substantially underestimates measurements of lumen area. Higher enhancement in larger vessels ensures more accurate subtraction of calcified plaque.

Background: There are limited data on the incidence of concussion and concussion symptom nondisclosure among collegiate women’s ice hockey athletes. Purpose: To determine the incidence of sports-related concussion (SRC) in National Collegiate Athletic Association (NCAA) women’s ice hockey athletes. Study Design: Descriptive epidemiology study. Methods: An anonymous online survey was completed by 459 NCAA women’s ice hockey athletes. Players reported diagnosed concussions as well as incidents where they experienced an impact or blow to the head followed by symptoms associated with a concussion; reports spanned the duration of the 2014-2015 season and throughout players’ organized hockey career. Results: About half (n = 219, 47.7%) of respondents reported at least 1 diagnosed concussion over the duration of their entire organized ice hockey career. A total of 13.3% (n = 61) of respondents reported a diagnosed concussion during the 2014-2015 season. The incidence rate was 1.18 (95% CI, 0.92-1.51) per 1000 athlete-exposures to a game or practice and 0.58 (95% CI, 0.45-0.74) per 1000 hours of ice time. One-third (34.2%, n = 157) of players reported at least 1 impact where they experienced concussion-like symptoms during the 2014-2015 season; 82.8% of these players reported that they continued to play after at least 1 of these impacts, and 66.8% of players reported at least 1 impact where they never disclosed any symptoms. Conclusion: There is a high incidence of SRC in collegiate women’s ice hockey and a concerning level of symptom nondisclosure. Additional research is needed to understand the causes of concussion and reasons for the lack of symptom disclosure, including factors specific to female athletes and contextual issues specific to women’s collegiate ice hockey.

Published: July 2017

Background: Anterior cruciate ligament (ACL) tear is the most frequent injury in alpine ski racing, and there is a high prevalence of ACL reinjury. Limited data exist on the concurrent pathology with primary ACL tears in elite alpine ski racers and the magnitude of injury progression after primary ACL reconstruction (ACLR). Purpose: To evaluate (1) the involvement of intra-articular and multiligament pathologies at the time of primary ACLR, (2) the subsequent progression in meniscal/chondral injuries, and (3) the occurrence of ACL reinjury in elite alpine ski racers. Study Design: Case series; Level of evidence, 4. Methods: Primary ACLR operative reports (n = 28) were obtained for 32 elite alpine ski racers along with the reports of 20 operative procedures that occurred subsequent to primary ACLR. Operative reports were evaluated to identify the presence/location of multiligament injury, meniscal tears, and chondral lesions. Results: At the time of primary ACLR, a majority of knees (82%; 23/28) demonstrated concurrent injury compared with isolated ACL tears; 32% of knees sustained multiligament injuries (9/28), and 8 involved the ipsilateral medial collateral ligament (MCL). Of the ACL-injured knees, 54% had chondral lesions, of which 73% were sustained in the lateral knee compartment, and 82% of meniscal tears (14/17) were complex in nature. Bilateral ACL tears were seen in 22% of the participants, and 28% underwent ACL revision. In the case of ACL revision or future meniscal/chondral surgery, 60% of meniscal tears and 80% of chondral lesions had worsened since the time of primary ACLR. Conclusion: Concurrent injury was common in this group of elite ski racers. Primary ACL tears were typically accompanied by lateral compartment chondral lesions and complex meniscal tears that worsened over time. ACL/MCL tears were the most common multiligament injury pattern.
How I monitor long-term and late effects after blood or marrow transplantation

Published: July 2017

Abstract
Blood or marrow transplantation (BMT) is used with curative intent for hematologic malignancies. Conditional on surviving the first 2 years after BMT, 5-year survival generally exceeds 70%. However, the cumulative therapeutic exposures lead to premature onset of chronic health conditions, such that the 15-year cumulative incidence of severe or life-threatening chronic health conditions exceeds 40%, resulting in premature mortality. The high burden of morbidity, coupled with a long latency between BMT and the development of chronic health conditions necessitates life-long risk-based monitoring of the BMT survivors. The issues of how and when to screen BMT survivors for therapy-related complications and exacerbation of preexisting conditions are important and largely unanswered questions. For BMT survivors, screening recommendations must incorporate risks associated with pre-BMT therapy as well as risks related to transplant conditioning and graft-versus-host disease. Here, we describe our approach to monitoring BMT survivors for risk-based screening and early detection of key late-occurring or long-term complications using patient scenarios to illustrate our discussion.
Experimental and computational studies of poly-L-lactic acid for cardiovascular applications: recent progress

AbstractStents are commonly used in medical procedures to alleviate the symptoms of coronary heart disease, a prevalent modern society disease. These structures are employed to maintain vessel patency and restore blood flow. Traditionally stents are made of metals such as stainless steel or cobalt chromium; however, these scaffolds have known disadvantages. An emergence of transient scaffolds is gaining popularity, with the structure engaged for a required period whilst healing of the diseased arterial wall occurs. Polymers dominate a medical device sector, with incorporation in sutures, scaffolds and screws. Thanks to their good mechanical and biological properties and their ability to degrade naturally. Polylactic acid is an extremely versatile polymer, with its properties easily tailored to applications. Its dominance in the stenting field increases continually, with the first polymer scaffold gaining FDA approval in 2016. Still some challenges with PLLA bioresorbable materials remain, especially with regard to understanding their mechanical response, assessment of its changes with degradation and comparison of their performance with that of metallic drug-eluting stent. Currently, there is still a lack of works on evaluating both the pre-degradation properties and degradation performance of these scaffolds. Additionally, there are no established material models incorporating non-linear viscoelastic behaviour of PLLA and its evolution with in-service degradation. Assessing these features through experimental analysis accompanied by analytical and numerical studies will provide powerful tools for design and optimisation of these structures endorsing their broader use in stenting. This overview assesses the recent studies investigating mechanical and computational performance of poly(l-lactic) acid and its use in stenting applications.

Published: July 2017

AbstractNocardioides dokdonensis, belonging to the class Actinobacteria, was first isolated from sand sediment of a beach in Dokdo, Korea, in 2005. In this study, we determined the genome sequence of FR1436, the type strain of N. dokdonensis, and analyzed its gene contents. The genome sequence is the second complete one in the genus Nocardioides after that of Nocardioides sp. JS614. It is composed of a 4,376,707-bp chromosome with a G + C content of 72.26%. From the genome sequence, 4,104 CDSs, three rRNA operons, 51 tRNAs, and one tmRNA were predicted, and 71.38% of the genes were assigned putative functions. Through the sequence analysis, dozens of genes involved in steroid metabolism, especially its degradation, were detected. Most of the identified genes were located in large gene clusters, which showed high similarities with the gene clusters in Pimelobacter simplex VKM Ac-2033D. Genomic features of N. dokdonensis associated with steroid catabolism indicate that it could be used for research and application of steroids in science and industry.

Κατά την περίοδο της κρίσης και των μνημονίων συντελούνται τεκτονικές αλλαγές στο περιεχόμενο των εργασιακών σχέσεων που οδηγούν στην απορρύθμιση της αγοράς εργασίας. Οι αλλαγές αυτές κινούνται στην ίδια κατεύθυνση, αλλά με εντονότερους όρους υπό το άλλοθι της κρίσης, με τις πολιτικές που καταγράφονται στην Ελλάδα στο πεδίο αυτό από τις αρχές της δεκαετίας του ’90, δημιουργώντας ένα εντελώς νέο εργασιακό τοπίο. Σε αυτό το πλαίσιο του νέου και πλήρως ευέλικτου εργασιακού προτύπου καταγράφεται η έντονη αμφισβήτηση της τυπικής μορφής εργασίας υπέρ των ευέλικτων εκφράσεών της, η αποδιάρθρωση του συστήματος των συλλογικών συμβάσεων και του τρόπου διαμόρφωσης των μισθών, η άρση της προστασίας από τις απολύσεις, η απελευθέρωση και η ελαστικοποίηση των ωραρίων, καθώς και η σύγκλιση των εργασιακών καθεστώτων στον ιδιωτικό και στον δημόσιο τομέα με όρους συνολικής υποβάθμισης. Οι εξελίξεις αυτές, που υπηρετούν τις επιλογές μείωσης και συμπίεσης του «εργατικού κόστους» στο όνομα της ανταγωνιστικότητας , συμβάλλουν στη δημιουργία και στην παγίωση μιας νέας κουλτούρας για την έννοια και το περιεχόμενο της εργασίας .Επίσης αποτελούν μέρος ενός πειράματος για την επέκταση των πολιτικών αυτών στον ευρωπαϊκό χώρο που έχει προ πολλού αποδεχθεί εργασιακές απορρυθμίσεις υπό το βάρος των κυρίαρχων νεοφιλελεύθερων δοξασιών.

Στη νεώτερη ελληνική ιστορία, η εκκλησιαστική εκπαίδευση συνυπάρχει με τον θεσμό των οικοτροφείων από τις αρχές του 19ου αι., σε όλες τις βαθμίδες. Η δημιουργία μορφωμένου κλήρου υπήρξε ρητά διατυπωμένος σκοπός στη σχετική νομοθεσία. Σε αυτήν περιλαμβάνονται ρυθμίσεις για τη δομή, οργάνωση και λειτουργία οικοτροφείων στην εκκλησιαστική εκπαίδευση. Τα οικοτροφεία, εκτός από παιδαγωγικούς και μαθησιακούς, υπηρετούν και κοινωνικούς στόχους. Σε αυτό το πλαίσιο αναλύονται οι προηγούμενες και οι ισχύουσες νομοθετικές προβλέψεις για τα οικοτροφεία εκκλησιαστικών εκπαιδευτικών ιδρυμάτων, με έμφαση στον Ν. 3432/2006 «Δομή και λειτουργία της Εκκλησιαστικής Εκπαίδευσης» και ειδικά την ίδρυση και λειτουργία της «Εστίας Εκκλησιαστικής Εκπαίδευσης». Παρουσιάζονται συνοπτικά, το περικείμενο της συγκεκριμένης μεταρρύθμισης, κυρίως δε το πλαίσιο των σχέσεων Κράτους – Εκκλησίας, ποσοτικά στοιχεία σχετικά με την εφαρμογή του Ν. 3432/2006 κατά τα έτη 2007-2014, και συγκριτικά ανάλογα στοιχεία που αφορούν την κρατική επιχορήγηση αντίστοιχων δομών σε ελληνικά πανεπιστήμια. Εξετάζεται η κοινωνική διάσταση στη λειτουργία της Εστίας Εκκλησιαστικής Εκπαίδευσης σε συνδυασμό με την υφιστάμενη οικονομική κρίση και διατυπώνονται προβληματισμοί για την προοπτική του θεσμού.

Published: July 2017

AbstractThe reactivity and stability of the edge faces of swelling clay minerals can be altered by layer charge and the stacking structure; however, these effects are poorly understood due to experimental limitations. The structure and stability of the montmorillonite {110}, {010}, {100}, and {130} edge faces with a layer charge of either y = 0.50 or y = 0.33 (e−/Si4O10) were investigated using first-principles calculations based on density functional theory. Stacked- and single-layer models were tested and compared to understand the effect of stacking on the stability of montmorillonite edge faces. Most stacked layers stabilize the edge faces by creating hydrogen bonds between the layers; therefore, the surface energy of the layers in the stacked-layer model is lower than in the single-layer model. This indicates that the estimates of edge face surface energy should consider the swelling conditions. Negative surface energies were calculated for these edge faces in the presence of chemisorbed water molecules. A high layer charge of 0.50 reduced the surface energy relative to that of the low layer charge of 0.33. The isomorphic substitution of Mg for Al increased the stability of interlayer Na ion positions, which were stable in the trigonal ring next to the Mg ions. The lowest surface energies of the {010} and {130} edge faces were characterized by the presence of Mg ions on edge faces, which had a strong cation adsorption site due to the local negative charge of the edges. The coordination numbers of O atoms around cations adsorbed to these edge faces were small in comparison to interlayers without water.
A phenomenological study of altered consciousness induced through movement
Authors: Deets Shannon Len 
Published: July 2017

Abstract
This study contributes to an understanding of phenomenal consciousness through analysing altered consciousness induced through authentic movement (ACIM). Data derived from qualitative interviews of sixteen participants (eight female, eight male) aged 24–62 years were analysed within Moustakas’ Transcendental Phenomenological Model. Participants’ dance experience varied from less than one year to over 50 years (mean seventeen years). Data yielded the theme of heightened awareness as the essence, with twenty one themes and five processes formulated into a phenomenal descriptive model of ACIM, harmonious within consciousness research across the disciplines of psychology, neuroscience, dance, anthropology and religion.
On dance and phenomenology: An essay interview with Professor Sondra Fraleigh, University of New York
Authors: Fraleigh Sondra , Williamson Amanda 
Published: July 2017

Abstract
In this extended essay interview with Sondra Fraleigh I ask about her paving-theway research in dance and phenomenology, and how the traditions of phenomenology historically and theoretically intersect within dance research paradigms. Together we cover questions and areas such as how and when phenomenological traditions started to integrate into Dance Studies, phenomenological approaches relative to somatics, and the ethical ramifications for students when phenomenology is taught and becomes a central research paradigm for dance studies students. Sondra shares her academic experience within these intersecting fields, and personal journeys and reflections within the intricacies and intimacies of phenomenological traditions.
Effect of Long-Term Ageing at 600 °C on Microstructure of ZG1Cr10MoWVNbN Martensitic Heat-Resistant Steel
Authors: Zhao Chengzhi , Li Ning , Zhao Yihan , Zhang Hexin 
Published: July 2017

AbstractA new kind of martensitic ZG1Cr10MoWVNbN heat-resistant steel has been attracted more attentions in recent years, which is mainly applied in ultra-supercritical steam turbines. The ageing property for ZG1Cr10MoWVNbN heat-resistant steel is very important because it often serves for long-time at high-temperature environment. Herein, a long-term ageing heat treatment was conducted on ZG1Cr10MoWVNbN steel at 600 °C heat for 17,000 hours. The microstructure evolution and property variation of the ZG1Cr10MoWVNbN steel were analysed before and after ageing, and also the effect of the precipitates on the mechanical properties was studied. The result showed that strength, the plastic index and impact power of the ZG1Cr10MoWVNbN steel were gradually decreased after long-term and high-temperature ageing at 600 °C due to the changes of martensite morphology and the coarsening of M23C6 carbide precipitation phase. Furthermore, fine precipitation of matrix MX carbide can also attribute to the change of mechanical properties at high temperature.
On Trend Breaks and Initial Condition in Unit Root Testing
Authors: Skrobotov Anton 
Published: July 2017

AbstractRecent approaches in unit root testing have taken into account the influences of initial conditions and data trend breaks via pre-testing and union of rejection testing strategies. This paper reviews existing methods, extends the methods of (Harvey, D. I., S. J. Leybourne, and A. M. R. Taylor. 2012b. “Unit Root Testing under a Local Break in Trend.”Journal of Econometrics167:140–167), and integrates these techniques to create a comprehensive testing strategy. Even when presented with nuisance parameters such as initial conditions and data breaks, this new strategy holds promising asymptotic and finite sample properties.
