Published: June 2017

Purpose Complete fibula absence often presents with significant lower-limb deformity. Parental counselling regarding management is paramount in achieving the optimum functional outcome. Amputation offers a single surgical event with minimal complications. This study compares outcomes with an amputation protocol to those using an extension prosthesis. Method Thirty-two patients were identified. Nine patients (2 males, 7 females; median age at assessment of 23.5 years) used an extension prosthesis. Twenty-three patients (16 males, 7 females; median age at assessment of eight years) underwent 25 amputations during childhood. Mobility was assessed using SIGAM and K scores. Quality of life was assessed using the PedsQL inventory questionnaire; pain by a verbal severity score. Results The 19 Syme and one Boyd amputation in 19 patients were performed early (mean age 15 months). Four Syme and one trans-tibial amputation in four patients took place in older children (mean age 6.6 years). Only two underwent tibial kyphus correction to aid prosthetic fitting. K scores were significantly higher (mean 4 vs 2) and pain scores lower in the amputation group allowing high impact activity compared with community ambulation with an extension prosthesis. The SIGAM and PedsQL scores were all better in the amputation group, but not significantly so. Conclusion Childhood amputation for severe limb length inequality and foot deformity in congenital fibula absence offers excellent short-term functional outcome with prosthetic support. The tibial kyphus does not need routine correction and facilitates prosthetic suspension. Accommodative extension prostheses offer reasonable long-term function but outcome scores are lower.
Resistants, stimulants and weaponization: Extreme metal music and empowerment in the Iraqi and Syrian civil conflicts
Authors: Grant Sam 
Published: June 2017

Abstract
Metal music can be a means of artistic expression or an accessory of war. Making its first appearance in Iraq and Syria in the 1980s, it has found function as an agency of power, endurance, anger and abuse. Utilizable by artists, fans and the military of the Mashriq, metal can be used for catharsis, rebellion or torture. This article looks at how the extreme metal subgenres of thrash metal, death metal and black metal have become important inclusions in the Iraqi and Syrian civil conflicts. Integrating original qualitative interview data from local bands, the study shows that metal music can be a source of empowerment for civilians as well as the US military. It also shows that metal can be the only stability some draw from during the continual devastation to their communities and that it can provide passage out of the region in exceptional circumstances.
The Viking raids of England in metal music: From ideology to parody
Authors: La Rocca Francesco 
Published: June 2017

Abstract
This article scrutinizes the rendition of the Viking imagery in metal music by the means of a comparative analysis of two Viking-inspired songs: ‘793 (The Battle of Lindisfarne)’ by the Enslaved, Norwegian Extreme band, and ‘Barbarian’ by The Darkness, the British rockers. Enslaved and The Darkness belong to widely different sub-genres of metal: the first cultivate an intriguing music characterized by Old-School Black Metal sounds blended with elements drawn from progressive rock, and the second are one of the most recognizable retro/heavy acts of the last two decades. Despite their widely different backgrounds, both bands have come up with two songs dealing with a particular aspect of early-Scandinavian history, namely, the Viking raids of Britain which took place in the VIII and IX centuries. It goes without saying that the differences between ‘793’ and ‘Barbarian’ reflect the styles and ideas of their respective composers: the juxtaposition of these contrasting musical and textual renditions of similar historical events (of particular relevance given also the borderline right-winged ideology propagated by Enslaved’s lyrics) will provide an innovative historical take on Viking-themed metal. I am grateful to the two anonymous reviewers from Metal Music Studies for a number of valuable suggestions.
Shredding, tapping and sweeping: Effects of guitar distortion on playability and expressiveness in rock and metal solos
Authors: Herbst Jan-Peter 
Published: June 2017

Abstract
‘Shredding’, the fast and virtuous guitar playing, is a central stylistic element of many rock and metal genres. A recent empirical study reported metal guitar solos having become faster over the last six decades, thus indicating that shredding still is common in metal guitar, as argued in the earlier literature in rock and metal music studies. The present study extends such research by experimentally investigating the effects of distortion on playability, virtuosity and expressiveness based on a multi-methodical analysis from musicology, acoustics and music informatics. The findings contribute to acoustic-based evidence of distortion’s simplifying effect that increases the electric guitar’s potential as a virtuoso solo instrument. Yet, the results also highlight challenges of distorted guitar playing less commonly considered in research, journalism and performance practice. The article closes by advocating greater acknowledgement of the skills required for distorted metal guitar playing.
From DJ to djent-step: Technology and the re-coding of metal music since the 1980s
Authors: Marrington Mark 
Published: June 2017

Abstract
This article considers the ways in which metal has interacted with the aesthetics of electronic music since the 1980s, from its earliest exchanges with hip hop through to recent developments in the djent subgenre. It highlights the persistence of metal’s practitioners in adopting new technologies (including samplers, drum machines and Digital Audio Workstations) and the challenges that this has brought to established ideas of conventional metal music practice. Underlying the discussion is the notion of the ‘code’, a familiar term in metal music studies, which has been employed to articulate ideas of metal’s core musical attributes. In these terms, electronic music’s creative practices can be seen to have facilitated both the deconstruction and re-contextualization of metal’s code, enabling the genre to be re-imagined and ultimately enriched.
‘Spooky action’: Transmission, composition and quantum entanglement
Authors: Connole Edia , Na R.iidr Vordb 
Published: June 2017

Abstract
With recourse to commentarial remarks on the composition of Moévöt’s Voèkrèb I (1994), in this short article we draw on ‘nonlocal’ correlations in quantum physics in an attempt to speculatively account for a creative process Vordb Na R.iidr (previously Vordb Báthor Ecsed: 1991–94; Vordb Dréagvor Uèzréèvb: 1994–2012) calls ‘instinctization’. Engaging the same conceit as Xasthur’s ‘Telepathic with the Deceased’, from the eponymous 2004 album (Moribund Records), the composition of Voèkrèb I forcibly returns us to the otherworldly aspects of a mode of transmission Einstein famously dubbed, ‘spooky action at a distance’ (spukhafte Fernwirkung).
Headbanging in Taiwan
Authors: Hsiang Chiu , de Seta Gabriele 
Published: June 2017

Abstract
Drawing on the authors’ sustained immersion and participation in local music scenes, this short article lays the groundwork for Taiwanese metal music studies. Heavy metal music arrived in Taiwan in the early 1980s through the precarious mediation of daoban [pirated] tapes and foreign television channels and, in the course of three decades, it has moved from a niche and hardly accessible genre to an established ensemble of scenes, subgenres, bands, venues, record labels, booking agencies, distributors, rehearsal spaces and audiences. After sketching a history of metal music in Taiwan in dialogue with a local record distributor, the authors describe how a subgenre such as death metal is practiced, discussed and sustained – through equipment, skills and judgments – during a few hours of a local band’s rehearsal. In light of the history, development and practice of metal music in Taiwan, more research about local bands, audiences and scenes appears urgent and necessary.

Authors: Gisella Luh Putu Gina , Chalid Dony Abdul 
Published: June 2017

Indonesia also have experienced the practice of Merger and Acquisition (M & A) transaction, like other parts of the world. This study aims to see if there are abnormal returns for the acquirer companies in M&A transactions that occurred in Indonesia, and also to test if there are some characteristics related to M&A that affects the abnormal returns. This study uses 143 M & A transaction data public company in Indonesia in 2005 until 2014. Event-study analysis was also conducted to find acquirer abnormal stock return around the announcement of M & A. In addition, OLS regression was also conducted to find whether the cash payment method in the M & A negatively affects the abnormal return. The condition of companies (Net Profit Margin, Sales Growth, firm value) also affect the abnormal return. This shows that the method of payment and acquire companies’ conditions have effects on the perception of investors towards M & A transactions that occured.
Reducing light scattering from surface contaminations by thin film design
Authors: Finck Alexander von , Wilbrandt Steffen , Stenzel Olaf , Schröder Sven 
Published: June 2017

Abstract
In most applications, contamination of optical thin film coatings is inevitable over time. State-of-the art approaches to tackle this problem are usually based on two strategies – avoiding contamination or removing already existing contamination. We demonstrate that the coating design can be tailored to reduce light scattering and stray light arising from particle contamination. This allows reducing the optical symptoms (light scattering) rather than trying to address the inevitable cause of the problem (contamination) itself. This new approach can consequently be easily combined with state-of-the-art approaches.

Abstract
In response to a sequence of dramatic accidents in research laboratories, [1, 2, 3] over the last five years the academic chemistry sector in the United States has focused on improving its safety culture and adopting more prudent laboratory practices. [4] Crucial to this effort is improved accessibility and management of chemical health and safety data and information tools that support laboratory process risk assessment. To this end, chemical safety, information, and education professionals are collaborating to facilitate and improve the risk assessment process for chemistry researchers and research students, as reported previously in Chemistry International.

Information overload: when less is more in medical imaging
Authors: Duncan James R. 
Published: June 2017

Abstract
In medicine, data collection and analysis provide the information needed to reduce diagnostic uncertainty. An examination of how medical imaging data is collected and then transformed into diagnostic information provides testable ideas for better managing this dynamic process. In other fields, process data is systematically assessed for differences between observed and predicted values. For studies that expose patients to the potentially harmful effects of ionizing radiation, monitoring imaging studies/illness, images/imaging study and radiation exposure/image would be steps towards developing radiation dose budgets for the diagnosis and treatment of common conditions. Random variation within the expected range would signal a high quality process. Conversely, single outlying cases or nonrandom variation within the expected range would trigger an investigation for a possible underlying cause. Such investigations would provide insights into how to continually improve this important aspect of healthcare.
Assigning responsibility to close the loop on radiology test results
Authors: Kwan Janice L. , Singh Hardeep 
Published: June 2017

Abstract
Failure to follow-up on test results represents a serious breakdown point in the diagnostic process which can lead to missed or delayed diagnoses and patient harm. Amidst discussions to ensure fail-safe test result follow-up, an important, yet under-discussed question emerges: how do we determine who is ultimately responsible for initiating follow-up action on the tests that are ordered? This seemingly simple question belies its true complexity. Although many of these complexities are also applicable to other diagnostic specialities, the field of medical imaging provides an ideal context to discuss the challenges of attributing responsibility of test result follow-up. In this review, we summarize several key concepts and challenges in the context of critical results, wet reads, and incidental findings to stimulate further discussion on responsibility issues in radiology. These discussions could help establish reliable closed-loop communication to ensure that every test result is sent, received, acknowledged and acted upon without failure.
First record of Platyrrhinus fusciventris (Chiroptera, Phyllostomidae) for the Caatinga biome
Authors: Rocha Patrício A. , Pedroso Mônica A. , Velazco Paúl M. 
Published: June 2017

Abstract
The Neotropical genus Platyrrhinus includes 21 small- to medium-sized bat species. Until recently, the known distribution of Platyrrhinus fusciventris in Brazil was restricted to the Amazon and Cerrado biomes. Herein, we report the easternmost record of this species, extending its distribution to the Caatinga biome, in Northeastern Brazil, Sergipe state. The specimen reported extends the known eastern limit of the species distribution by more than 800 km, suggesting that this species, although preferring rainforest habitats, also possesses the plasticity to exploit resources of the seasonal dry forests, as the Caatinga.

Authors: Maranescu Bianca , Lupa Lavinia , Visa Aurelia 
Published: June 2017

Abstract
The increase attention in the area of phosphonate metal organic framework is exemplified with a variety of applications and a rich chemistry of these compounds. Water pollution caused by heavy metal ions is a major concern due to their toxicity to many life forms. In order to decrease the heavy metals impact upon the environment various technologies of water treatment such as: chemical sedimentation, ion exchange, redox process are studied. The tendency is to find a versatile and economical method of heavy metals removal from waste waters. Phosphonate metal organic frameworks were obtained by the reaction of Ni(CH3COO)2·4H2O, phosphonic acid (phosphonoacetic (CP), vinyl phosphonic acid (VP) and N,N-bis(phosphonomethyl)glycine (Gly)) in hydrothermal conditions. Coordination polymers synthesized were characterized by FTIR, XRD, scanning electron microscopy (SEM) and thermal gravimetric analysis (TGA). The adsorption processes represent a very good alternative for heavy metals removal due to low costs and ease of operation. In the present paper the adsorption performance of the mentioned materials in the removal process of heavy metals from aqueous solutions, was studied using the batch method. The adsorption conditions were investigated by varying the initial pH, contact time and adsorbate initial concentration for chromium metal ions removal from aqueous solutions. It was found that the adsorption efficiency of the studied materials in the removal process of Cr(VI) ions from aqueous solutions is in the following order: Ni-CP<Ni-Gly≤Ni-VP.

Published: June 2017

Abstract
From the earlier studies in physical and chemical sciences, it is found that the physico-chemical characteristics of chemical compounds are internally connected with their molecular structures. As a theoretical basis, it provides a new way of thinking by analyzing the molecular structure of the compounds to understand their physical and chemical properties. In our article, we study the physico-chemical properties of certain molecular structures via computing the Ediz eccentric connectivity index from mathematical standpoint. The results we yielded mainly apply to the techniques of distance and degree computation of mathematical derivation, and the conclusions have guiding significance in physical engineering.
Pteridine determination in human serum with special emphasis on HPLC methods with fluorimetric detection
Authors: Espinosa-Mansilla Anunciación , Durán-Merás Isabel 
Published: June 2017

Abstract
Conjugated and unconjugated pteridines and their derivatives are important cofactors in cellular metabolism. Hence, the amount of unconjugated pteridines in biological fluids has been found to be modified as a result of several disorders. It is necessary to note that while for the control of pteridines in urine samples there are numerous reference data, the literature referred to for the analysis of these analytes in serum/plasma is scarce. In biological fluids, pteridines can exist in different oxidation states, and these compounds can be classified into two groups according to: (a) oxidized or aromatic pteridines and (b) reduced pteridines. Oxidized pteridines yield a strong fluorescence signal, whereas reduced pteridines present a low quantum yield of fluorescence. In order to enable the analysis of the reduced forms, several preoxidation procedures to generate aromatic rings have been established. Also, stabilization of the reduced forms by the addition of reducing agents has been widely reported. The objective of this paper is to show possibilities and different approaches in the analysis of pteridines in serum samples. We have mainly focused on the description of the current situation in the application of high-performance chromatography methods with fluorimetric detection.
Dicholoroacetate exerts anti-cancer activity on human renal cell carcinoma cells
Authors: Kalay Saban , Dogan Aysegul , Turkan Ali , Demiroglu-Zergeroglu Asuman 
Published: June 2017

Abstract

Aim
Impaired mitochondrial function is a consequence of HIF1-induced overexpression of pyruvate dehydrogenase kinase (PDK) which phosphorylates and inactivates pyruvate dehydrogenase multi-enzyme complex (PDC), which converts pyruvate to acetyl-CoA for entry into the TCA cycle. Shifting cancer cells from glycolysis to oxidative phosphorylation induces apoptosis, which is a new therapeutic strategy by utilizing PDK inhibitors. In this work, the effect of PDK inhibitor, dichloroacetate (DCA) has been investigated in Human renal carcinoma cell line.

Methods
Adherent epithelium renal cell adenocarcinoma (ACHN) cells were treated with different concentrations of DCA at different time periods. Cell viability was measured by WST assay, cell-cycle profile and apoptosis were assessed by using flow cytometry. Metabolites of the cell extracts were analyzed by LC-MS/MS.

Results
DCA reduced cell viability in a concentration- and time-dependent manner. Treatment with DCA induced G1 arrest and apoptosis in ACHN cells. Additionally, metabolite changes of ACHN cell line upon DCA treatments showed that lactate, citrate, N-acetylaspartate and 5-oxoproline levels, which were high in untreated cells, significantly reduced upon DCA treatment.

Conclusion
Potential anti-carcinogenic effects of DCA, including inhibition of cell proliferation and growth, and induction of apoptosis, as well as the ability of markedly reducing lactate levels make this agent a promising drug candidate in renal adenocarcinomas.

Abstract

Objective
The aim of this study was to synthesize ten 1,4-dihydropyridine (DHP) derivatives in which substituted cyclohexane rings were fused to the DHP ring and to determine how different ester groups and the benzoyl substituent introduced in 4-phenyl ring affected their calcium channel blocking activity.

Methods
A microwave-assisted one-pot method was applied for the synthesis of compound 1–5 according to a modified Hantzsch reaction. The benzoyl moiety was introduced in the 4-phenyl ring of these dihydropyridines by refluxing with benzoyl chloride in acetone in the presence of anhydrous potassium carbonate. Synthesized products were characterized by elemental analysis, IR, 1H-NMR and 13C-NMR spectroscopy. The inhibitory actions of compounds 1–10 on calcium channel blocking activity were tested on isolated rat aorta preparations.

Results
The obtained pharmacological results showed that although all compounds are potent relaxing agents on isolated rat aorta smooth muscle, introduction of a benzoyloxy substitiuent on the phenyl ring (compound 6–10) decreased the relaxant effect of these compunds.

Conclusion
The reported 1,4-DHP derivatives have calcium channel blocking activity on rat aorta smooth muscle.
