Published: August 2017

Aims Our aim was to evaluate the radiographic characteristics of patients undergoing total hip arthroplasty (THA) for the potential of posterior bony impingement using CT simulations. Patients and Methods Virtual CT data from 112 patients who underwent THA were analysed. There were 40 men and 72 women. Their mean age was 59.1 years (41 to 76). Associations between radiographic characteristics and posterior bony impingement and the range of external rotation of the hip were evaluated. In addition, we investigated the effects of pelvic tilt and the neck/shaft angle and femoral offset on posterior bony impingement. Results The range of external rotation and the ischiofemoral length were significantly lower, while femoral anteversion, the ischial ratio, and ischial angle were significantly higher in patients with posterior bony impingement compared with those who had implant impingement (p < 0.05). The range of external rotation positively correlated with ischiofemoral length (r = 0.49, p < 0.05), and negatively correlated with ischial length (r = -0.49, p < 0.05), ischial ratio (r =- 0.49, p < 0.05) and ischial angle (r = -0.55, p < 0.05). The range of external rotation was lower in patients with posterior pelvic tilt (p < 0.05) and in those with a high offset femoral component (p < 0.05) due to posterior bony impingement. Conclusion Posterior bony impingement after THA is more likely in patients with a wider ischium and a narrow ischiofemoral space. A high femoral offset and posterior pelvic tilt are also risk factors for this type of impingement. Cite this article: Bone Joint J 2017;99-B:1140–6.
Sliding hip screw versus the Targon PFT nail for trochanteric hip fractures
Authors: Parker M. J. , Cawley S. 
Published: August 2017

Aims To compare the outcomes for trochanteric fractures treated with a sliding hip screw (SHS) or a cephalomedullary nail. Patients and Methods A total of 400 patients with a trochanteric hip fracture were randomised to receive a SHS or a cephalomedullary nail (Targon PFT). All surviving patients were followed up to one year from injury. Functional outcome was assessed by a research nurse blinded to the implant used. Results Recovery of mobility, as assessed by a mobility scale, was superior for those treated with the intramedullary nail compared with the SHS at eight weeks, three and nine months (p-values between 0.01 and 0.04), the difference at six and 12 months was not statistically significant (p = 0.15 and p = 0.18 respectively). The mean difference was around 0.4 points (0.3 to 0.5) on a nine point scale. Surgical time for the nail was four minutes less than that for the SHS (p < 0.001). Fracture healing complications were similar for the two groups. There were no statistically significant differences between implants for any other recorded outcomes including the need for post-operative blood transfusion, wound healing complications, general medical complications, hospital stay or mortality. Conclusion This study confirms the findings of a previous study that both methods of treatment produce similar results, although intramedullary fixation does result in marginally improved regain of mobility in comparison with the SHS.

Contemporary acetabular fracture surgery
Authors: Rickman M. , Varghese V. D. 
Published: August 2017

In the time since Letournel popularised the surgical treatment of acetabular fractures, more than 25 years ago, there have been many changes within the field, related to patients, surgical technique, implants and post-operative care. However, the long-term outcomes appear largely unchanged. Does this represent stasis or have the advances been mitigated by other negative factors? In this article we have attempted to document the recent changes within the surgery of patients with a fracture involving the acetabulum, outline contemporary management, and identify the major problem areas where further research is most needed.Cite this article: Bone Joint J 2017;99-B:1125–31
Three-dimensional knee kinematic analysis during treadmill gait
Authors: Mannering N. , Young T. , Spelman T. , Choong P. F. 
Published: August 2017

Objectives Whilst gait speed is variable between healthy and injured adults, the extent to which speed alone alters the 3D in vivo knee kinematics has not been fully described. The purpose of this prospective study was to understand better the spatiotemporal and 3D knee kinematic changes induced by slow compared with normal self-selected walking speeds within young healthy adults. Methods A total of 26 men and 25 women (18 to 35 years old) participated in this study. Participants walked on a treadmill with the KneeKG system at a slow imposed speed (2 km/hr) for three trials, then at a self-selected comfortable walking speed for another three trials. Paired t-tests, Wilcoxon signed-rank tests, Mann-Whitney U tests and Spearman’s rank correlation coefficients were conducted using Stata/IC 14 to compare kinematics of slow versus self-selected walking speed. Results Both cadence and step length were reduced during slow gait compared with normal gait. Slow walking reduced flexion during standing (10.6° compared with 13.7°; p < 0.0001), and flexion range of movement (ROM) (53.1° compared with 57.3°; p < 0.0001). Slow walking also induced less adduction ROM (8.3° compared with 10.0°; p < 0.0001), rotation ROM (11.4° compared with 13.6°; p < 0.0001), and anteroposterior translation ROM (8.5 mm compared with 10.1 mm; p < 0.0001). Conclusion The reduced spatiotemporal measures, reduced flexion during stance, and knee ROM in all planes induced by slow walking demonstrate a stiff knee gait, similar to that previously demonstrated in osteoarthritis. Further research is required to determine if these characteristics induced in healthy knees by slow walking provide a valid model of osteoarthritic gait. Cite this article: N. Mannering, T. Young, T.

The media ecology of play: A preliminary probe of childhood play in the digital age
Authors: Albrecht Robert , Tabone Carmine 
Published: August 2017

Abstract
In this article, the authors argue that children today, because of the digital environment in which they are growing up, have much less opportunity to engage in forms of play that require direct face-to-face communication. Building upon some suggestions made by Neil Postman, the authors probe the media ecology of play and how it has been fundamentally reconfigured in the digital age. What does digital technology do and undo to the traditional experience of childhood play? How do traditional oral-based forms of play differ from play that is digitally mediated? What are some of the ideas embedded in the digital mediation of play that need to be teased out and more carefully considered? Finally, reflecting on their own work with children over the past four decades, the authors offer a pragmatic response that both parallels the emphasis placed by John Huizinga in his book Homo Ludens on the primacy of play in the evolution of culture and, at the same time, strongly reflects the view advocated by Neil Postman in his book Teaching As a Conserving Activity of creating a ‘thermostatic mechanism’ that would counterbalance the dominant presence of electronic media in the lives of children.
Window rhetoric: Curtains, drapes and blinds

Published: August 2017

Abstract
Taking Wayne C. Booth's efforts to widen the definition of rhetoric, Augustine's remarks on ‘signs’ and ‘things’, Martin Heidegger's remarks on logos as points of departure, this article explores the rhetorical effects and implications of ordinary glass windows and their different but typical coverings, and how the double logos of windows alters and varies according to how windows are covered and how much or little is concealed by these coverings.
Ripe for revolution? The role of loud popular music in revolutionary social and political processes
Authors: Haukkala Hiski 
Published: August 2017

Abstract
Rock ‘n’ roll, metal music included, is often portrayed as revolutionary music. There is indeed some evidence that loud popular music (LPM) has preceded, or at least been associated with radical political changes in authoritarian regimes, the dissolution of the Soviet Union being the most illustrious example. But very little is known about the causal and social mechanisms that could account for these effects. This is the lacuna that this article seeks to fill by addressing the following two questions: What is the causal link between LPM and authoritarian unravelling? What are the physiological, psychological and social processes at play? The article will pay special attention to the level of individuals, seeking to develop a set of conceptual mechanisms that account for the effects of LPM on individuals that help make them proto-revolutionaries ‘ripe for revolution’. The article will also include empirical examples, using the historical case of the Singing Revolution in the Estonian Soviet Socialist Republic at the turn of the 1990s and describing how these mechanisms have operated in practice. Similarly, the article will contain a concluding section that ponders the relevance of these mechanisms in the present situation of the changing metal business and markets and that addresses the question of whether LPM will continue to have revolutionary effects in the future.

Pharmacological activities of some triazinopyrazolothieno pyrimidine derivatives
Authors: Bahashwan Saleh A. 
Published: August 2017

Abstract
Triazinopyrazolothieno pyrimidine derivatives 1–5 were evaluated for their anti-inflammatory, analgesic and anticancer activities and acute toxicity. Anti-inflammatory activity of the compounds was studied using the carrageenan test. All tested compounds showed analgesic activity, 3-methoxycarbonyl-4,6-dimethyl-8-[(N-methylindolyl)methyl] pyrimido [5′,4′:4,5]thieno [3′,2′-3,4]pyrazolo [5,1-c]triazine (4) showed activity comparable to that of diclofenac. Compounds 1–5 were also screened for anticancer activity on a human lung cancer cell line (A549) and a human prostate cancer cell line (DU145) using the MTT micro-cultured tetrazolium assay method. Compound 4 showed also significant anticancer activity against both cancer cell lines, comparable to that of doxorubicin. The most active compounds were tested for their acute toxicity and median lethal doses were evaluated.
Green ultrasound-assisted three-component click synthesis of novel 1H-1,2,3-triazole carrying benzothiazoles and fluorinated-1,2,4-triazole conjugates and their antimicrobial evaluation
Authors: Rezki Nadjet , Aouad Mohamed Reda 
Published: August 2017

Abstract
The present study describes an efficient and ecofriendly, ultrasound, one-pot click cycloaddition approach for the construction of a novel series of 1,4-disubstituted-1,2,3-triazoles tethered with fluorinated 1,2,4-triazole-benzothiazole molecular conjugates. It involved three-component condensation of the appropriate bromoacetamide benzothiazole, sodium azide and 4-alkyl/aryl-5-(2-fluorophenyl)-3-(prop-2-ynylthio)-1,2,4-triazoles 4a-e through a Cu(I)-catalyzed 1,3-dipolar cycloaddition reaction. This approach involves in situ generation of azidoacetamide benzothiazole, followed by condensation with terminal alkynes in the presence of CuSO4/Na-ascorbate in aqueous DMSO under both conventional and ultrasound conditions. Some of the designed 1,2,3-triazole conjugates 6a-o were recognized for their antimicrobial activity against some bacterial and fungal pathogenic strains.

Published: August 2017

Abstract
A novel series of carbamothioylamino-benzene-sulfonamide-thiophene-carboxylates 4a-c and thieno[3,2-d]pyrimidin-2-yl-amino-benzene-sulfonamides 5a-c were synthesized in a series of synthetic steps and were used as key intermediates for the synthesis of thienotriazolopyrimidine-benzene-sulfonamide derivatives 6a-c and 7a-c. Thieno[3,2-d]pyrimidinones (8 and 9) were also prepared. Compound 9 was used as an intermediate for the synthesis of imidazole/1,2,4-triazole and tetrazine functionalized thieno[3,2-d]pyrimidine derivatives (10–12). Pyrrole derivatives/pyrrolopyrimidine/pyrrolotriazolopyrimidine functionalized thiophenes (15–19) were also synthesized. Structures of the newly synthesized compounds were established by elemental analysis and spectral data. Most of the newly synthesized compounds were evaluated for their in vitro activity against three human tumor cell lines, namely, liver cancer (HepG-2), colon cancer (HT-29) and lung cancer (NCI-H460), using doxorubicin as standard. Compounds 16 (GI
50 = 0.02, 0.04 and 0.06 μmol L−1, resp.) and 19b (GI
50 = 0.02, 0.03 and 0.05 μmol L−1, resp.) showed higher activity against all cell lines than doxorubicin. Most of the compounds were also screened for antibacterial activity using ciprofloxacin as standard drug. Compounds 4b and 6b, both containing benzenesulfonamide linked to N-, 10 bearing imidazole moiety, and 15 and 19b,c with a thiophene-2-carboxylic acid chain, exhibited high activity against Gram-positive and Gram-negative bacteria.
Ein enzyklopädisches Ereignis: Thomas Prischuchs ›Grundvest‹ des Konstanzer Konzils (1417/18)
Authors: Herweg Mathias 
Published: August 2017

Abstract
In the final stages of the Council of Constance (1414–1418), just six hundred years ago, Thomas Prischuch, a patrician from Augsburg and visitor to the Council, composed a rhymed poem on the Council, entitled the Council’s ›Grundvest‹. It is usually considered an example of political-propagandistic poetry (›politische Ereignisdichtung‹). However, the multitude of catalogues inserted, collecting and imparting knowledge, suggests a different reading, which is supported by the transmission context of the text. Prischuch’s poem establishes the Council as a generator and agent of knowledge and as a universal, encyclopedic event. It is not so much a political, as it is an encyclopedic poem. At the same time, the effort to transform the Council into a matter of encyclopedia serves to underpin the Council’s order and its decisions. Only by this the poem is also a political statement: it reflects the hope for change that Prischuch’s contemporaries attached to the Council as well as, looking ahead to the year 1517, the frustration of these very same hopes.

Abstract

Objective. Thrombotic thrombocytopenic purpura (TTP) is a rare disease characterized by microangiopathic hemolytic anemia, thrombocytopenic purpura, neurologic abnormalities, fever, and renal insufficiency. The association or co-existence of thyrotoxicosis or antithyroid drugs with TTP has not been previously reported.

Subject and Results. Herein, we present a 54-year-old female patient newly diagnosed with toxic multinodular goiter accompanying with TTP, possibly triggered by either thyrotoxicosis or antithyroid drugs.

Conclusions. The present report is the first in the literature to demonstrate the co-existence of these two diseases and the use of plasma exchange as a modality to treat both conditions.
“Pop-in” and “pop-out” effect in monocrystalline silicon. A statistical investigation
Authors: Sidiropoulos Alexandros D. , Harea Evghenii , Konstantinidis Avraam A. , Aifantis Elias C. 
Published: August 2017

AbstractPop-in and pop-out effects in silicon (Si) have long been known. They were evidenced in the indentation loading-unloading curves as a sudden displacement discontinuity. They consist in a sudden contraction (pop-in) or a sudden expansion (pop-out) of the material underneath the indenter in a short period of time and are attributed to Si phase transformations that take place during the nanoindentation procedure. In this paper, first we provide a statistic analysis of such pop-in/pop-out events depending on the maximum indentation load and second we examine the dependence of their appearance on the indentation loading-unloading rate.
Determining the Prevalence and Correlates of Information Seeking Anxiety Among Postgraduates in Pakistan
Authors: Naveed Muhammad Asif , Ameen Kanwal 
Published: August 2017

AbstractThis study examined the prevalence and correlatives of information seeking anxiety in postgraduate students of the University of the Punjab, Lahore using Information Seeking Anxiety Scale (ISAS). The participants’ selection was made using a stratified convenient sampling due to non-availability through random process. Postgraduate students were approached through a questionnaire, containing ISAS and demographic variables, with descriptive and inferential statistics used for data analysis. Results indicated the prevalence of information seeking anxiety among postgraduates as a large majority of the sample did face more than low anxiety for overall ISAS and all its sub-scales. Participants’ age, gender, faculty, program of study, study stage, computer proficiency, and research experience also appeared to be correlatives to the information seeking anxiety. These useful insights had serious implications to viable information literacy (IL) programs and could be used as a guide by academic information professionals managing information services, especially those engaged in IL instructions.
A System Dynamics Approach of Users’ Dynamic Behavior for Mobile Services in Academic Library
Authors: Li Lirui , Deng Zhonghua 
Published: August 2017

AbstractThe application and innovation of mobile library services are changing the way users communicate and access information. As academic libraries provide users with ubiquitous services, the need to holistically explore the transformation mechanism of different levels of users driven by their dynamic behavior of mobile services assumes greater importance. The systems thinking perspective is used as a tool to relate to key factors, interactional processes and feedback outcomes. The system dynamics model is used to present two scenario-based tests so as to evaluate influences of managing the value of relationship of different levels of users, with an emphasis on participation and collaboration with users, while three different purposive types of users are also identified, need, exploration and interest orientation, to reflect the effectiveness of adopting. Mobile service providers can meet individuation and diversification of users’ demands in the process of providing dynamic services by discerning and clustering user types timely. The developed model can serve as a systematic explanation or effective reference tool for the development of mobile libraries under a variety of circumstances.

Abstract
Chalcogenide glasses have attracted much attention largely due to their interesting physical and chemical properties. Though few published articles exist on the As-Te system, little is known about the optical properties of eutectic or near eutectic composition of As-Te system upon heat treatment. Therefore, this paper reports the effects of annealing temperature on the structural and optical parameters of As30Te70 thin films. The bulk and thin films of 150 nm thick As30Te70 chalcogenide glasses were prepared by melt-quenching and thermal evaporation techniques, respectively. The glass transition and crystallization reactions of the bulk samples were investigated using differential scanning calorimetry (DSC). The influence of annealing temperature on the transformation of the crystal structure was studied by X-ray diffraction (XRD), while the surface morphology of the annealed samples was examined using scanning electron microscope (SEM). The optical band gap, refractive index and extinction coefficient were also calculated. The DSC scans showed that the melting temperature remains constant at 636.56 K. In addition, other characteristic temperatures such as the glass transition temperature, the onset crystallization temperature, and the crystallization peak temperature increase with increasing the heating rate. The crystalline phases for the as-prepared and annealed films consist of orthorhombic As, hexagonal Te, and monoclinic As2Te3 phases. Furthermore, the average crystallite size, strain, and dislocation density depend on the annealing temperature. The optical absorption results revealed that the investigated films have a direct transition, and their optical energy gap decreases from 1.82 eV to 1.49 eV as the annealing temperature increases up to 433 K. However, the refractive index, extinction coefficient, dielectric constant and the ratio of free carrier concentration to its effective mass, increase with increasing the annealing temperature.

Abstract
The evolutionary theories of mutation accumulation (MA) and disposable soma (DS) provide possible explanations for the existence of human aging. To better understand the relative importance of these theories, we devised a test to identify MA- and DS-consistent sites across the genome using familial DNA methylation data. Two key characteristics of DNA methylation allowed us to do so. First, DNA methylation exhibits distinct and widespread changes with age, with numerous age-differentially-methylated sites observed across the genome. Second, many sites show heritable DNA methylation patterns within families. We extended heritability predictions of MA and DS to DNA methylation, predicting that MA-consistent age-differentially-methylated sites will show increasing heritability with age, while DS-consistent sites will show the opposite. Variance components models were used to test for changing heritability of methylation with age at 48,601 age-differentially-methylated sites across the genome in 610 individuals from 176 families. Of these, 102 sites showed significant MA-consistent increases in heritability with age, while 2266 showed significant DS-consistent decreases in heritability. These results suggest that both MA and DS play a role in explaining aging and aging-related changes, and that while the majority of DNA methylation changes observed in aging are consistent with epigenetic drift, targeted changes exist and may mediate effects of aging-related genes.
