What is a predatory journal? A scoping review
Authors: Cobey Kelly D. , Lalu Manoj M , Skidmore Becky , Ahmadzai Nadera , Grudniewicz Agnes , Moher David 
Published: August 2018

Background: There is no standardized definition of what a predatory journal is, nor have the characteristics of these journals been delineated or agreed upon. In order to study the phenomenon precisely a definition of predatory journals is needed. The objective of this scoping review is to summarize the literature on predatory journals, describe its epidemiological characteristics, and to extract empirical descriptions of potential characteristics of predatory journals. Methods: We searched five bibliographic databases: Ovid MEDLINE, Embase Classic + Embase, ERIC, and PsycINFO, and Web of Science on January 2nd, 2018. A related grey literature search was conducted March 27th, 2018. Eligible studies were those published in English after 2012 that discuss predatory journals. Titles and abstracts of records obtained were screened. We extracted epidemiological characteristics from all search records discussing predatory journals. Subsequently, we extracted statements from the empirical studies describing empirically derived characteristics of predatory journals. These characteristics were then categorized and thematically grouped. Results: 920 records were obtained from the search. 344 of these records met our inclusion criteria. The majority of these records took the form of commentaries, viewpoints, letters, or editorials (78.44%), and just 38 records were empirical studies that reported empirically derived characteristics of predatory journals. We extracted 109 unique characteristics from these 38 studies, which we subsequently thematically grouped into six categories: journal operations, article, editorial and peer review, communication, article processing charges, and dissemination, indexing and archiving, and five descriptors. Conclusions: This work identified a corpus of potential characteristics of predatory journals. Limitations of the work include our restriction to English language articles, and the fact that the methodological quality of articles included in our extraction was not assessed. These results will be provided to attendees at a stakeholder meeting seeking to develop a standardized definition for what constitutes a predatory journal.

Published: August 2018

Background:The ribosomal protein S6 kinase 1 (S6K1) is one of the main components of the mTOR/S6K signal transduction pathway, which controls cellular metabolism, autophagy, growth, and proliferation. Overexpression of S6K1 was detected in tumors of different origin including breast cancer, which was associated with a worse disease outcome. In addition, significant accumulation of S6K1 was found in the nuclei of breast carcinoma cells suggesting the implication of kinase nuclear substrates in tumor progression. However, this aspect of S6K1 functioning is poorly understood. The main aim of the present work was to study the subcellular localization of S6K1 in breast cancer cells with focus on cell migration.Methods:Multicellular spheroids of MCF-7 cells were generated using agarose-coated Petri dishes. Cell migration was initiated by spheroids seeding onto growth surface and subsequent cultivation for 24 and 72 hours. S6K1 subcellular localization was studied in human breast cancer and normal tissue, 2D and 3D MCF-7 cell culture using immunofluorescence analysis and confocal microscopy.Results:Analysis of histological sections of human breast cancer and normal tissue revealed predominantly nuclear localization of S6K1 in breast malignant cells and mainly cytoplasmic one in conditionally normal cells.In vitrostudies of MCF-7 cells showed that the subcellular localization of S6K1 depends on the cell density in the monolayer culture. S6K1 relocalization from the cytoplasm into the nucleus was detected in MCF-7 cells migrating from multicellular spheroids onto growth surface. Immunofluorescence analysis of S6K1 and immunocoprecipitation assay revealed the colocalization and interaction between S6K1 and transcription factor TBR2 (T-box brain protein 2) in MCF-7 cells. Bioinformatical analysis revealed existence of several phosphorylation sites in TBR2 for S6K1 suggesting that TBR2 can be a target for phosphorylation and regulation by S6K1.Conclusions:Subcellular localization of S6K1 depends on the density and locomotor activity of the MCF-7 cells.
Chinese young generation’s perceptions and consumption of clothing for sustainability
Authors: DeLong Marilyn , Wu Juanjuan , Jia Zhenyu , Gibson Laureen 
Published: August 2018

Abstract
This research explored the concept of sustainability related to the clothing practices of design students attending a university in Shanghai. Participants included 29 males and 36 female students who completed a survey about their wearing of specific clothing categories, their perceptions of the importance of the need for sustainability in the clothing they wear and sustainable practices regarding their clothing. Data were analysed, compared between the genders, and summarized. Within this context, students reported wearing their clothing a relatively short time while at the same time considering awareness of clothing sustainability important. Also, the students’ sustainable practices and strategies were found to be more geared towards care and use but neglecting purchase decisions and disposable methods. We postulated that Shanghai economy is influential as are the student’s expectations for gaining status through their clothing. These students’ views of sustainability and their clothing practices are important as they will become designers in the future and will play a leading role in the fields of applied arts.
Conscious hip hop: Lupe Fiasco’s critical teachings on raced and gendered representations
Authors: Woods Alyssa , Burns Lori 
Published: August 2018

Abstract
This article examines the critical pedagogy of Lupe Fiasco’s music video ‘Bitch Bad’ (2012). Situating Fiasco’s work as an instance of hip hop teaching, we propose an analytic model to facilitate the interpretation of genre conventions evident in the multimodal music video text. We place genre theory into dialogue with critical discourse analysis in order to bring forward the ideologies, social values and cultural norms invoked in Fiasco’s portrayal of hip hop video actors and spectators. The analysis reveals Lupe Fiasco’s and videographer Gil Green’s critique of racist and misogynist stereotypes perpetuated in the music industry. Fiasco and Green present the hip hop performer as a labourer who is asked to portray specific conventions of gender, race and class. They explore the impact of the genre conventions upon children who grow up in the context of these cultural norms; they situate Fiasco as a cultural critic and teacher; and they demonstrate the potential of the music video to function as a pedagogical text.
Holistic educational ideals and pedagogy of trust within popular music education in civil society
Authors: Söderman Johan 
Published: August 2018

Abstract
Through directing focus towards hip-hop culture and aspects of young people’s learning in after-school hip-hop activities for participants 13 years and older within Swedish state-funded study associations, this article is guided by the following question: What meanings do hip-hop activities have for participants and rappers who function as ‘organic’ educators within Swedish study associations? The empirical data were produced through interviews with participants and rappers who function as organic hip-hop educators in Swedish study associations. The term ‘organic’ is used to underline how rappers, without formal education, have developed pedagogical skills through educating others. In light of holistic educational ideals, rappers and their pedagogical work can be understood to contrast the dominant trend in western education of instrumental and narrow perspectives and approaches to learning.
Balance de la evaluación de políticas públicas en América Latina en el presente siglo
Authors: Fernández Edgardo Ricardo Romero , Cano Eduardo Romero 
Published: August 2018

El proceso de las políticas públicas, adoptado por Latinoamérica, está asociado a la idea de desarrollo y a la democracia participativa -frente al análisis profesional vinculado a una institucionalidad desde su forma representativa- como profundo rechazo a los regímenes dictatoriales que asolaron la región en el pasado siglo. La institucionalización de la evaluación en América Latina coincide con los procesos de reforma del Estado y nuevo constitucionalismo y muchas de las reformas propuestas desde finales de los 80´s se dirigieron a combatir el híper-presidencialismo y la limitada participación ciudadana. Mas, los sistemas de seguimiento y evaluación nacional son en rigor simples sistemas de seguimiento, que no generan posibilidades de evaluación exhaustiva. Aun con esas dificultades, los procesos y evaluación de programas y políticas avanzaron con asistencia técnica y metodológica de organismos internacionales. Existen publicaciones periódicas que robustecen el proceso de institucionalización, ocupándose mayormente de las temáticas referentes a la política pública. Ello – de conjunto a la celebración sistemática de congresos y eventos de organismos internacionales que abordaron la temática- expresa el proceso de academización de las políticas públicas. Aunque el mismo estuvo marcado por el sectorialismo y el pragmatismo. Se reconoce una cantidad alta de escritos y acciones en América Latina sobre evaluación, solo que muchos de los trabajos, informes y reportes, sobre evaluación no son identificables con evaluación de política pública sino con otros procesos o formas de la política desde enfoques asistencialistas (sociales) o verticalistas (estatales).
The role of interleukins 17, 23 and antibodies to the thyroid-stimulating hormone receptor in the pathogenesis of endocrine ophthalmopathy
Authors: Charinzeva Svetlana V. , Taskina Elizaveta S. 
Published: August 2018

Background. Endocrine ophthalmopathy (EOP) is an autoimmune orbit disease characterized by soft retrobulbar tissues damage. The level of antibodies to the thyroid-stimulating hormone receptor (TSHRAbs) is considered as a laboratory marker of EOP activity. Interleukins 17 (IL-17) and 23 (IL-23) play an important role in the pathogenesis of some autoimmune diseases and directly correlate with clinical activity. At present, there is an open question about the role of these cytokines in EOP and their relationship with TSHRAbs.
Aims. To assess pathogenetic role of IL-17, IL-23 and TSHRAbs in patients with EOP.
Materials and methods. The study included 50 people (100 eyes) at the age of 43 [35; 50] years. Three study groups were formed: 32 patients with moderate severity of EOP (clinical group), 18 patients with thyroid pathology without EOP (comparison group) and 15 healthy subjects (control group). All groups were comparable in age and sex. The diagnosis was verified clinically, laboratory and instrumentally. A comprehensive ophthalmologic examination and blood sampling were performed to determine the concentrations of IL-17, IL-23 and TSHRAbs. Statistical processing of the data was carried out in the program “Statistica 10.0”, StatSoft, Inc.
Results. An increase in the level of TSHRAbs was observed in all phases of EOP activity in comparison with both comparison group and control (p < 0.05). But in the active phase TSHRAbs level reached the maximum values in 100% of patients. An increase in the IL-17 concentration in 5,3 times was found in the active EOP in comparison with the control group (p < 0.05). Concentration of TSHRAbs and IL-17 in blood serum directly correlates with EOP activity (p < 0.001). After carrying out pulse therapy with glucocorticosteroids, the consentration of IL-17 decreased almost to zero. There were no significant differences in the level of IL-23 in the groups (p = 0.56).
Conclusions. Determination of TSHRAbs and IL-17 levels in serum can be used as a laboratory diagnostic marker of EOP activity.
New adventures of the median urinary iodine
Authors: Gerasimov Gregory A. 
Published: August 2018

From the beginning of the 1990s until the end of the 2000s, Russian thyroidology developed under the auspice of “median ioduria”. The emergence of available techniques, such as urinary iodine analysis and the estimation of thyroid volume by ultrasonography, multiplied by the vast expanses of Russia, gave researchers an uncultivated field for epidemiological studies. In the course of the research, there were sometimes difficulties in interpreting the data identified in the epidemiological studies, which was partly due to the imperfection of the then existing international guidelines. In 2018, UNICEF and the Iodine Global Network (IGN) released updated recommendations based on an analysis of the experience and mistakes of the past 10–15 years. In his regular column, the author discusses new approaches to monitoring of iodine prophylaxis programs, in which the “median of ioduria” remains a central piece.
Radon measure-valued solutions of first order scalar conservation laws

AbstractWe study nonnegative solutions of the Cauchy problem{∂t⁡u+∂x⁡[φ⁢(u)]=0in ⁢ℝ×(0,T),u=u0≥0in ⁢ℝ×{0},\left\{\begin{aligned} &\displaystyle\partial_{t}u+\partial_{x}[\varphi(u)]=0&% &\displaystyle\phantom{}\text{in }\mathbb{R}\times(0,T),\\ &\displaystyle u=u_{0}\geq 0&&\displaystyle\phantom{}\text{in }\mathbb{R}% \times\{0\},\end{aligned}\right.whereu0{u_{0}}is a Radon measure andφ:[0,∞)↦ℝ{\varphi\colon[0,\infty)\mapsto\mathbb{R}}is a globally Lipschitz continuous function. We construct suitably defined entropy solutions in the space of Radon measures. Under some additional conditions on φ, we prove their uniqueness if the singular part ofu0{u_{0}}is a finite superposition of Dirac masses. Regarding the behavior of φ at infinity, we give criteria to distinguish two cases: either all solutions are function-valued for positive times (an instantaneous regularizing effect), or the singular parts of certain solutions persist until some positivewaiting time(in the linear caseφ⁢(u)=u{\varphi(u)=u}this happens for all times). In the latter case, we describe the evolution of the singular parts.

Aberrant glycosylation and cancer biomarker discovery: a promising and thorny journey
Authors: Wang Mengmeng , Zhu Jianhui , Lubman David M. , Gao Chunfang 
Published: August 2018

AbstractGlycosylation is among the most important post-translational modifications for proteins and is of intrinsic complex character compared with DNAs and naked proteins. Indeed, over 50%–70% of proteins in circulation are glycosylated, and the “sweet attachments” have versatile structural and functional implications. Both the configuration and composition of the attached glycans affect the biological activities of consensus proteins significantly. Glycosylation is generated by complex biosynthetic pathways comprising hundreds of glycosyltransferases, glycosidases, transcriptional factors, transporters and the protein backbone. In addition, lack of direct genetic templates and glyco-specific antibodies such as those commonly used in DNA amplification and protein capture makes research on glycans and glycoproteins even more difficult, thus resulting in sparse knowledge on the pathophysiological implications of glycosylation. Fortunately, cutting-edge technologies have afforded new opportunities and approaches for investigating cancer-related glycosylation. Thus, glycans as well as aberrantly glycosylated protein-based cancer biomarkers have been increasingly recognized. This mini-review highlights the most recent developments in glyco-biomarker studies in an effort to discover clinically relevant cancer biomarkers using advanced analytical methodologies such as mass spectrometry, high-performance liquid chromatographic/ultra-performance liquid chromatography, capillary electrophoresis, and lectin-based technologies. Recent clinical-centered glycobiological studies focused on determining the regulatory mechanisms and the relation with diagnostics, prognostics and even therapeutics are also summarized. These studies indicate that glycomics is a treasure waiting to be mined where the growth of cancer-related glycomics and glycoproteomics is the next great challenge after genomics and proteomics.

Published: August 2018

Abstract
Thalassemia is one of the most common hereditary disorders of the developing world, and it is associated with severe anemia and transfusion dependence. The global health burden of thalassemia has increased as a result of human mobility and migration in recent years. Depending on inherited mutations, thalassemia patients exhibit distorted hemoglobin (Hb) patterns and deviated red cell indices, both of which can be used to support identification by diagnostic tools. Diagnostic approaches vary depending on the target population and the aim of the testing. Current methods, which are based on Hb patterns, are used for first-line screening, whereas molecular testing is needed for conformation of the results and for prenatal and preimplantation genetic diagnosis. In the present paper, we review the diagnostic parameters, pitfalls, interfering factors, and methods; currently available best-practice guidelines; quality assurance and standardization of the procedures; and promising laboratory technologies for the future of thalassemia diagnosis.
Titanium dioxide-benzophenone hybrid as an effective catalyst for enhanced photochemical degradation of low density polyethylene
Authors: Nguyen Thi Kim Ngan , Kim Hong Gun , Kwac Lee Ku , Bui Quoc Bao , Nguyen Dang Mao , Jeong Hun 
Published: August 2018

Abstract
In this study, a hybrid of titanium dioxide, benzophenone and ethylene vinyl acetate (TiO2-BP-EVA) was used as a novel catalyst to accelerate photo-oxidization reaction of low-density polyethylene (LDPE) film under ambient conditions. The degradation of the LDPE films (thickness of ~25 μm) containing different catalyst concentrations were successfully investigated by different techniques, such as Fourier-transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (SEM), differential scanning calorimetry (DSM), thermogravimetric analysis (TGA) and mechanical tests. The results showed that the use of catalyst in which TiO2-BP content (1/3 w/w) is 0.5 phr (parts per hundred resin) and EVA content is 4.5 phr in a LDPE film provided the best degradation rate. The carbonyl index of the polymer film achieved the highest value without an equilibrium stage. Besides, the carbon-carbon backbone of the polymer was completely broken down consistent with the deformation of the surface. In addition, the mechanical properties impressively dropped after 3 months’ exposure. The obtained results imply that the TiO2-BP-EVA compound can be considered as an efficient catalyst for the photodegradation of LDPE polymer.
Multiple binding sites in organic cation transporters require sophisticated procedures to identify interactions of novel drugs
Authors: Koepsell Hermann 
Published: August 2018

Abstract

In vitro evaluation of drugs for interaction with transporters is essential during drug development. As polyspecific organic cation transporters (OCTs) are critical for pharmacokinetics of many cationic drugs, in vitro testing of human OCT1 and human OCT2 is recommended. In the currently applied tests it is determined whether uptake of one model cation in stably transfected epithelial cells is inhibited using a substrate concentration in the micromolar range. In this review experimental evidence for the existence of low- and high-affinity cation binding sites in OCTs that may interact with drugs is compiled. Most data were obtained from studies performed with rat Oct1. Whereas overlapping low-affinity cation binding sites are directly involved in transport, the high-affinity cation binding sites may induce allosteric inhibition of transport. Remarkably, high-affinity inhibition is only observed when uptake is measured using nanomolar substrate concentrations far below the respective K
m values. Affinities of inhibitors are dependent on molecular structure and concentration of the employed substrate. Because the currently applied in vitro tests for identification of interaction of novel drugs with OCTs do not consider the influence of substrate structure and are not capable of identifying high-affinity inhibition, more sophisticated testing protocols are proposed.
MicroRNA-1225-5p acts as a tumor-suppressor in laryngeal cancer via targeting CDC14B
Authors: Sun Peng , Zhang Dan , Huang Haiping , Yu Yafeng , Yang Zhendong , Niu Yuyu , Liu Jisheng 
Published: August 2018

Abstract
This study aimed to investigate the role of miRNA-1225-5p (miR-1225) in laryngeal carcinoma (LC). We found that the expression of miR-1225 was suppressed in human LC samples, while CDC14B (cell division cycle 14B) expression was reinforced in comparison with surrounding normal tissues. We also demonstrated that enhanced expression of miR-1225 impaired the proliferation and survival of LC cells, and resulted in G1/S cell cycle arrest. In contrast, reduced expression of miR-1225 promoted cell survival. Moreover, miR-1225 resulted in G1/S cell cycle arrest and enhanced cell death. Further, miR-1225 targets CDC14B 3′-UTR and recovery of CDC14B expression counteracted the suppressive influence of miR-1225 on LC cells. Thus, these findings offer insight into the biological and molecular mechanisms behind the development of LC.
Converting pairing-based cryptosystems from composite to prime order setting – A comparative analysis
Authors: Chatterjee Sanjit , Prem Laxman Das M. , Kabaleeshwaran R. 
Published: August 2018

Abstract
Composite order pairing setting has been used to achieve cryptographic functionalities beyond what is attainable
in prime order groups. However, such pairings are known to be significantly slower than their prime order counterparts. Thus emerged a new line of research – developing frameworks to convert cryptosystems from composite to prime order pairing setting.
In this work, we analyse the intricacies of efficient prime order instantiation of cryptosystems that can be converted using existing frameworks. To compare the relative efficacy of these frameworks we mainly focus on some representative schemes: the Boneh–Goh–Nissim (BGN) homomorphic encryption scheme, ring and group signatures as well as a blind signature scheme. Our concrete analyses lead to several interesting observations. We show that even after a considerable amount of research, the projecting framework implicit in the very first work of Groth–Sahai still remains the best choice for instantiating the BGN cryptosystem.
Protocols like the ring signature and group signature which use both projecting and cancelling setting in composite order can be most efficiently instantiated in the Freeman prime-order projecting only setting. In contrast, while the Freeman projecting setting is sufficient for the security reduction of the blind signature scheme, the simultaneous projecting and cancelling setting does provide some efficiency advantage.
