Principais queixas osteomusculares em músicos da região do ABC paulista: um estudo de prevalência
Authors: Reijani Nádia , Benetti Fernanda Antico
Published: May 2016

Introdução: Os músicos são profissionais com diversos fatores predisponentes a desenvolver o adoecimento ocupacional. Na maioria das vezes, eles apresentam queixas graves. A conscientização do músico para os riscos que ele pode sofrer e os métodos de prevenção são essenciais para evitar maiores danos que possam impedir a prática da atividade que o profissional exerce, uma vez que a música é relacionada ao bem-estar, ao equilíbrio emocional e ao divertimento. Objetivo: Levantar dados e analisar quais são as principais queixas osteomusculares dos músicos devido à postura adquirida na prática instrumentista. Métodos: A amostra conteve 80 músicos estudantes e profissionais da Associação Cultural Tocando a Vida, da Big Band da Fundação das Artes de São Caetano do Sul e da Orquestra Sinfônica Jovem da Fundação das Artes de São Caetano do Sul. Esses músicos passaram por uma triagem e posteriormente responderam o Questionário Nórdico de Sintomas Osteomusculares. Resultados: Foi observado que, para todas as famílias de instrumentos, a metade ou mais apresentam dor causada pela prática instrumentista. Conclusão: Pode-se concluir que as regiões das mãos e da coluna tanto dorsal quanto lombar foram os locais mais afetados pela prática instrumentista independente de a qual família o instrumento pertença. Não foi possível analisar e relacionar a prevalência das lesões osteomusculares dos músicos, pois a grande maioria não realizava acompanhamento médico e não apresentava diagnóstico clínico.

Deep-level transient spectroscopy of low-free-carrier-concentration n-GaN layers grown on freestanding GaN substrates: Dependence on carbon compensation ratio
Authors: Tanaka Takeshi , Shiojima Kenji , Mishima Tomoyoshi , Tokuda Yutaka
Published: May 2016

Electron traps in n-GaN layers with a relatively low-free-carrier-concentration of approximately 1 × 1016 cm−3 were characterized by deep-level transient spectroscopy. Sample layers were grown by metal organic chemical vapor deposition with a thickness of 12 µm on freestanding GaN substrates, and were doped with both silicon and carbon. The measurement results showed a reduction in the density of carbon-related electron traps at an energy level of E
C −0.40 eV in GaN on GaN samples, compared with GaN on SiC samples. It was also observed that the doping of carbon significantly suppressed electron traps at E
C −0.61 eV, which was associated with the nitrogen antisite. Consequently, the possibility of minimizing all of the electron traps located between E
C −0.19 and −0.89 eV in n-GaN was demonstrated by controlling the carbon doping in the nitrogen site.

Objectives

The purpose of this study was to investigate the interobserver, intraobserver, and intermethod reliability of computer‐assisted digital and manual measurements of hip sonograms.

Methods

Seventy‐four hip sonograms were evaluated in this retrospective study. Five evaluators measured digital images and manual paper printouts according to the Graf method (Arch Orthop Trauma Surg 1984; 102:248–255). Interobserver and intraobserver reliability rates were calculated. Reliability criteria were graded on a numeric scale.

Results

The interobserver reliability of both computer‐based and manual methods for alpha angle measurements was good to excellent, but the interobserver reliability was fair to poor for beta angle measurements. Intraobserver reliability was varied. Alpha angle measurements by both manual and computer‐based methods had high concordance with each other, whereas beta angle measurements had low concordance. The intermethod variability did not differ between observers.

Conclusions

The alpha angle measurements had high concordance with each other for both manual and computer‐based methods, whereas the beta angle measurements had low concordance. This information should be taken into account in clinical practice. Overall, the two measurement methods were reliable and consistent with each other.
IGF2BP2 promotes colorectal cancer cell proliferation and survival through interfering with RAF‐1 degradation by miR‐195
Authors: Ye Song , Song Wei , Xu Xiaogang , Zhao Xinyi , Yang Liu
Published: May 2016

Insulin‐like growth factor 2 (IGF2) mRNA‐binding protein 2 (IGF2BP2) is a post‐transcriptional regulatory factor implicated in mRNA localization, stability, and translational control. However, the role of IGF2BP2 regulation in colorectal cancer (CRC) and its underlying mechanism remain elusive. In this study, we found that IGF2BP2 expression is markedly increased in CRC tissues. Notably, IGF2BP2 overexpression strikingly enhanced the proliferation and survival of CRC cells in vitro, whereas its shRNA‐mediated silencing resulted in the opposite. Molecular function analyses revealed that IGF2BP2 regulates RAF1 expression through blocking its degradation by miR‐195. These results identify IGF2BP2 as a post‐transcriptional regulatory mRNA‐binding factor that contributes to CRC carcinogenesis.
Estimating climate sensitivity using two‐zone energy balance models
Authors: Bates J. Ray
Published: May 2016

Estimates of 2 × CO2 equilibrium climate sensitivity (EqCS) derive from running global climate models (GCMs) to equilibrium. Estimates of effective climate sensitivity (EfCS) are the corresponding quantities obtained using transient GCM output or observations. The EfCS approach uses an accompanying energy balance model (EBM), the zero‐dimensional model (ZDM) being standard. GCM values of EqCS and EfCS vary widely [Intergovernmental Panel on Climate Change range: (1.5, 4.5)°C] and have failed to converge over the past 35 years. Recently, attempts have been made to refine the EfCS approach by using two‐zone (tropical/extratropical) EBMs. When applied using satellite radiation data, these give low and tightly constrained EfCS values, in the neighborhood of 1°C. These low observational EfCS/two‐zone EBM values have been questioned because (a) they disagree with higher observational EfCS/ZDM values and (b) the EfCS/two‐zone EBM values given by GCMs are poorly correlated with the standard GCM sensitivity estimates. The validity of the low observational EfCS/two‐zone EBM values is here explored, with focus on the limitations of the observational EfCS/ZDM approach, the disagreement between the GCM and observational radiative responses to surface temperature perturbations in the tropics, and on the modified EfCS values provided by an extended two‐zone EBM that includes an explicit parameterization of dynamical heat transport. The results support the low observational EfCS/two‐zone EBM values, indicating that objections (a) and (b) to these values both need to be reconsidered. It is shown that in the EBM with explicit dynamical heat transport the traditional formulism of climate feedbacks can break down because of lack of additivity.
Idealized climate change simulations with a high‐resolution physical model: HadGEM3‐GC2

Published: May 2016

Idealized climate change simulations with a new physical climate model, HadGEM3‐GC2 from The Met Office Hadley Centre are presented and contrasted with the earlier MOHC model, HadGEM2‐ES. The role of atmospheric resolution is also investigated. The Transient Climate Response (TCR) is 1.9 K/2.1 K at N216/N96 and Effective Climate Sensitivity (ECS) is 3.1 K/3.2 K at N216/N96. These are substantially lower than HadGEM2‐ES (TCR: 2.5 K; ECS: 4.6 K) arising from a combination of changes in the size of climate feedbacks. While the change in the net cloud feedback between HadGEM3 and HadGEM2 is relatively small, there is a change in sign of its longwave and a strengthening of its shortwave components. At a global scale, there is little impact of the increase in atmospheric resolution on the future climate change signal and even at a broad regional scale, many features are robust including tropical rainfall changes, however, there are some significant exceptions. For the North Atlantic and western Europe, the tripolar pattern of winter storm changes found in most CMIP5 models is little impacted by resolution but for the most intense storms, there is a larger percentage increase in number at higher resolution than at lower resolution. Arctic sea‐ice sensitivity shows a larger dependence on resolution than on atmospheric physics.
Engineering Substrate Interactions for High Luminescence Efficiency of Transition‐Metal Dichalcogenide Monolayers

Published: May 2016

It is demonstrated that the luminescence efficiency of monolayers composed of MoS2, WS2, and WSe2 is significantly limited by the substrate and can be improved by orders of magnitude through substrate engineering. The substrate affects the efficiency mainly through doping the monolayers and facilitating defect‐assisted nonradiative exciton recombinations, while the other substrate effects including straining and dielectric screening play minor roles. The doping may come from the substrate and substrate‐borne water moisture, the latter of which is much stronger than the former for MoS2 and WS2 but negligible for WSe2. Using proper substrates such as mica or hexagonal boron nitride can substantially mitigate the doping effect. The defect‐assisted recombination depends on the interaction between the defect in the monolayer and the substrate. Suspended monolayers, in which the substrate effects are eliminated, may have efficiency up to 40% at room temperatures. The result provides useful guidance for the rational design of atomic‐scale light emission devices.

Novel hafnium oxide (HfO2)‐based ferroelectrics reveal full scalability and complementary metal oxide semiconductor integratability compared to perovskite‐based ferroelectrics that are currently used in nonvolatile ferroelectric random access memories (FeRAMs). Within the lifetime of the device, two main regimes of wake‐up and fatigue can be identified. Up to now, the mechanisms behind these two device stages have not been revealed. Thus, the main scope of this study is an identification of the root cause for the increase of the remnant polarization during the wake‐up phase and subsequent polarization degradation with further cycling. Combining the comprehensive ferroelectric switching current experiments, Preisach density analysis, and transmission electron microscopy (TEM) study with compact and Technology Computer Aided Design (TCAD) modeling, it has been found out that during the wake‐up of the device no new defects are generated but the existing defects redistribute within the device. Furthermore, vacancy diffusion has been identified as the main cause for the phase transformation and consequent increase of the remnant polarization. Utilizing trap density spectroscopy for examining defect evolution with cycling of the device together with modeling of the degradation results in an understanding of the main mechanisms behind the evolution of the ferroelectric response.

Published: May 2016

To achieve high performance for inverted structure perovskite solar cells, the design of hole‐transporting layer (HTL) and related interfacial engineering are very important tasks. To avoid the hygroscopic characteristics of poly (3, 4‐ethylenedioxythiophene):poly (styrenesulfonate) that may degrade the adjacent moisture‐sensitive perovskite layer, here, a new CrOx‐based hole‐transport material has been introduced. The feasibility of fabrication efficient perovskite solar cells with CrOx and Cu‐CrOx as HTLs is confirmed for the first time. Cu doping can modify the chromium ion contents and suppress the formation of surface hydroxylation and CrO3 in the CrOx film, which can increase work function, electrical conductivity, and carrier mobility of the CrOx films. Consequently, the power conversion efficiency of the corresponding device increases to 10.99% from its original value of 9.27%. This study not only provides a novel HTL system for high performance and decently stable optoelectronic devices but also reveals the importance of HTL doping for interface engineering.

Choosing Wisely (CW) is a medical stewardship initiative led by the American Board of Internal Medicine Foundation in collaboration with professional medical societies in the United States. In an effort to learn from and leverage the work of others, the American Society of Hematology CW Task Force developed a method to identify and prioritize CW recommendations from other medical societies of high relevance and importance to patients with blood disorders and their physicians. All 380 CW recommendations were reviewed and assessed for relevance and importance. Relevance was assessed using the MORETM relevance scale. Importance was assessed with regard to six guiding principles: harm avoidance, evidence, aggregate cost, relevance, frequency and impact. Harm avoidance was considered the most important principle. Ten highly relevant and important recommendations were identified from a variety of professional societies. Recommendations focused on decreasing unnecessary imaging, blood work, treatments and transfusions, as well as on increasing collaboration across disciplines and considering value when recommending treatments. Many CW recommendations have relevance beyond the society of origin. The methods developed by the ASH CW Task Force could be easily adapted by other Societies to identify additional CW recommendations of relevance and importance to their fields. Am. J.

Published: May 2016

The development of high‐sensitive, and cost‐effective novel biosensors have been strongly desired for future medical diagnostics. To develop novel biosensor, the authors focused on the specific optical characteristics of photonic crystal. In this study, a label‐free optical biosensor, polymer‐based two‐dimensional photonic crystal (2D‐PhC) film fabricated using nanoimprint lithography (NIL), was developed for detection of C‐reactive protein (CRP) in human serum. The nano‐hole array constructed NIL‐based 2D‐PhC (hole diameter: 230 nm, distance: 230, depth: 200 nm) was fabricated on a cyclo‐olefin polymer (COP) film (100 µm) using thermal NIL and required surface modifications to reduce nonspecific adsorption of target proteins. Antigen‐antibody reactions on the NIL‐based 2D‐PhC caused changes to the surrounding refractive index, which was monitored as reflection spectrum changes in the visible region. By using surface modified 2D‐PhC, the calculated detection limit for CRP was 12.24 pg/mL at an extremely short reaction time (5 min) without the need for additional labeling procedures and secondary antibody. Furthermore, using the dual‐functional random copolymer, CRP could be detected in a pooled blood serum diluted 100× with dramatic reduction of nonspecific adsorption. From these results, the NIL‐based 2D‐PhC film has great potential for development of an on‐site, high‐sensitivity, cost‐effective, label‐free biosensor for medical diagnostics applications
Coordinated transcription factor and promoter engineering to establish strong expression elements in Saccharomyces cerevisiae
Authors: Leavitt John M. , Tong Alice , Tong Joyce , Pattie Jonathan , Alper Hal S.
Published: May 2016

Gene expression requires the coordination of trans‐acting factors and cis‐DNA elements to initiate transcription. Here we present a coordinated approach that combines cis‐acting element engineering with mutant trans‐acting factors to engineer yeast promoters. Specifically, we first construct a hybrid promoter based on the ARO9 upstream region that exhibits high constitutive and inducible expression with respect to exogenous tryptophan. Next, we perform protein engineering to identify a mutant Aro80p that affords both high constitutive expression while retaining inducible traits. We then use this mutant trans‐acting factor to drive expression and generate ultra‐strong promoters with transcriptional output roughly 2 fold higher than TDH3 (GPD), one of the strongest promoters to‐date. Finally, we used this element to construct a modular expression system capable of staged outputs resulting in a system with nearly 6‐fold, 12‐fold and 15‐fold expression relative to the off‐state. This work further highlights the potential of using endogenous transcription factors (including mutant factors) along with hybrid promoters to expand the yeast synthetic biology toolbox.

Published: May 2016

Flos Chrysanthemi, dried flower of Chrysanthemum morifolium Ramat, has drawn much attention recently owing to its potential beneficial health effects for human. Flos Chrysanthemi products are usually taken orally and metabolized by intestinal microflora. However, there has been no investigation of the comprehensive metabolic profile of the Flos Chrysanthemi extract by intestinal flora owing to its chemical complexity and the limitations of analytical methods. In this paper, a rapid, sensitive and automated analysis method, ultra‐performance liquid chromatography/quadrupole time of flight mass spectrometry including MSE technology and automated data processing Metabolynx™ software, was developed and successfully applied for the biotransformation and metabolic profile of flavonoids in the Flos Chrysanthemi extract by intestinal flora from human and rat. A total of 32 metabolites were detected and tentatively identified in human and rat intestinal bacterial samples. These metabolites indicated that hydrolysis, hydroxylation, acetylation, methylation, hydrogenation and deoxygenation were the major conversion pathways of flavonoids in the Flos Chrysanthemi extract in vitro. Furthermore, the effects of the Flos Chrysanthemi extract on the growth of different intestinal bacteria were detected using an Emax precision microplate reader. Certain pathogenic bacteria such as Enterobacter, Enterococcus, Clostridium and Bacteroides were significantly inhibited by Flos Chrysanthemi, while commensal probiotics such as Lactobacillus and Bifidobacterium were moderately promoted. Our observation provided further evidence for the importance of intestinal bacteria in the metabolism and potential activity of the Flos Chrysanthemi extract. The results will also be helpful for the further pharmacokinetic study of Flos Chrysanthemi and to unravel how it works in vivo.
Protest Against Waste Contamination in the ‘Land of Fires’: Psychological Antecedents for Activists and Non‐activists
Authors: Scafuto Francesca , La Barbera Francesco
Published: May 2016

The ‘Land of Fires’ is a district in Italy characterized by illegal waste disposal, waste burning, and citizen protests over contamination. This study investigates the relevance of several psycho‐social factors that predict citizens' intention to protest, taking into account different research traditions. In addition, we hypothesize the effect of protest antecedents to be moderated by past participation behaviour (i.e. the level of activism). Hence, our study is a first attempt to explore the effect of protest antecedents as a function of the individual level of activism through a cross‐sectional survey study (N = 306). The results show significant effects of collective identity, sense of injustice, costs of protest, and perceived risk (cognitive dimension) on intention to protest. The effects of collective efficacy and perceived risk (affective dimension) are moderated by participants' level of activism, and these effects are significant only for non‐activists. The relevance of this new approach is discussed, as well as practical implications and possible further developments. Copyright © 2016 John Wiley & Sons, Ltd.
On the Permeation by Dioxygen of Urate Oxidase from Aspergillus flavus in Complex with Xanthine Anion: Dioxygen Pathways and a Portrait of the Enzyme Cavities from Molecular Dynamics Simulations in Water Solution
Authors: Pietra Francesco
Published: May 2016

This work describes molecular dynamics (MD) simulations in aqueous media for the complex of the homotetrameric urate oxidase (UOX) from Aspergillus flavus with xanthine anion (5) in the presence of dioxygen (O2). After 196.6 ns of trajectory from unrestrained MD, a O2 molecule was observed leaving the bulk solvent to penetrate the enzyme between two subunits, A/C. From here, the same O2 molecule was observed migrating, across subunit C, to the hydrophobic cavity that shares residue V227 with the active site. The latter was finally attained, after 378.3 ns of trajectory, with O2 at a bonding distance from 5. The reverse same O2 pathway, from 5 to the bulk solvent, was observed as preferred pathway under random acceleration MD (RAMD), where an external, randomly oriented force was acting on O2. Both MD and RAMD simulations revealed several cavities populated by O2 during its migration from the bulk solvent to the active site or backwards. Paying attention to the last hydrophobic cavity that apparently serves as O2 reservoir for the active site, it was noticed that its volume undergoes ample fluctuations during the MD simulation, as expected from the thermal motion of a flexible protein, independently from the particular subunit and no matter whether the cavity is filled or not by O2.

One‐Step Synthetic Access to Isosteric and Potent Anticancer Nitrogen Heterocycles with the Benzo[c]phenanthridine Scaffold
Authors: Steinhauer Tamara N. , Girreser Ulrich , Meier Christopher , Cushman Mark , Clement Bernd
Published: May 2016

A versatile one‐step two‐component cyclization to build new tetracyclic nitrogen heterocycles is described. Ortho‐methylhetarenecarbonitrile components were condensed with aldehydes to access a large library of differently substituted ring systems. The heterocyclic core can be easily modified by variation of the position of the endocyclic nitrogen atom in the o‐methylhetarenecarbonitrile substrate. The manner of the nucleophilic attack that leads to the condensation can be triggered by different electron‐density distribution in the molecule induced by the position of the nitrogen atom. Taking this into account, there is an electronic preference that leads to either pyridophenanthrolines or the corresponding pyridoazacarbazoles as the main products. We demonstrate the high antitumor potential of some of our synthesized heterocycles, which is strongly dependent on the substitution pattern introduced through the aldehyde component. The position and number of endocyclic nitrogen atoms play an important role regarding cytotoxicity of the studied compounds.
Advantages of Catalysis in Self‐Assembled Molecular Capsules
Authors: Catti Lorenzo , Zhang Qi , Tiefenbacher Konrad
Published: May 2016

Control over the local chemical environment of a molecule can be achieved by encapsulation in supramolecular host systems. In supramolecular catalysis, this control is used to gain advantages over classical homogeneous catalysis in bulk solution. Two of the main advantages concern influencing reactions in terms of substrate and product selectivity. Due to size and/or shape recognition, substrate selective conversion can be realized. Additionally, noncovalent interactions with the host environment facilitate alternative reaction pathways and can yield unusual products. This Concept article discusses and highlights literature examples utilizing self‐assembled molecular capsules to achieve catalytic transformations displaying a high degree of substrate and/or product selectivity. Furthermore, the advantage of supramolecular hosts in multicatalyst tandem reactions is covered.
Helically Assembled Pyrene Arrays on an RNA Duplex That Exhibit Circularly Polarized Luminescence with Excimer Formation
Authors: Nakamura Mitsunobu , Suzuki Junpei , Ota Fuyuki , Takada Tadao , Akagi Kazuo , Yamana Kazushige
Published: May 2016

Circularly polarized luminescence (CPL) was observed in pyrene zipper arrays helically arranged on an RNA duplex. Hybridization of complementary RNA strands having multiple (two to five) 2′‐O‐pyrenylmethyl modified nucleosides affords an RNA duplex with normal thermal stability. The pyrene fluorophores are assembled like a zipper in a well‐defined helical manner along the axis of RNA duplex, which, upon 350 nm UV illumination, resulted in CPL emission with pyrene excimer formation. CPL (glum) levels observed for the pyrene arrays in dilute aqueous solution were +2×10−2–+3.5×10−2, which are comparable with |glum| for chiral organic molecules and related systems. The positive CPL signals are consistent with a right‐handed helical structure. Temperature dependence on CPL emission indicates that the stable rigid RNA structure is responsible for the strong CPL signals. The single pyrene‐modified RNA duplex did not show any CPL signal.
