Authors: Páramo Aguilera Leandro Alberto , Narváez Zapata José Alberto , Ortega Morales Benjamín Otto
Published: December 2015

Partiendo de 30 aislados bacterianos de diferentes tipos (fundamentalmente Bacillus), previamente aislados e identificados por métodos microbiológicos y moleculares, provenientes de biopelículas epilíticas traídas del Castillo de Chapultepec de la ciudad de México, DF. Se realizaron diferentes metodologías como comprobación y determinación de formación biopelículas y su cuantificación, prueba de ureasa y la producción de cristales de carbonato de calcio en placa Petry con LB enriquecido con carbonato de calcio al 0.2 %. Los cristales fueron enviados a difracción de rayos X y Microscopia Electrónica de Barrido.Los resultados muestran que en alguna medida todos los microorganismos probados  participan en el proceso de formación de biopelículas y un total de 12 aislados destacaron como los mejores formadores de biopelículas, sobresaliendo las cepas IS16 y IIIS10 (Bacillus subtilis), IIS15a (Bacillus cereus) por ser las que mayores UFC/mL presentaron en la biopelícula. Todos los buenos formadores de biopelículas resultan también adecuados en cuanto a bioprecipitación de carbonatos, destacando las cepas IIIS4 (Bacillus megaterium), IS5 (Bacillus subtilis) e IIIS9b (Bacillus subtilis), 21 (Pantoea agglomerans) y la IIIS5 (Bacillus simplex). Poco o nada se sabe hasta el momento de la participación de Pantoea agglomerans en procesos de biorrestauración mediante bioprecipitación de cristales de carbonato de calcio y debido a que se obtuvo buena respuesta a la prueba de ureasa y los cristales obtenidos fueron mayormente Calcita (99 %), este trabajo muestra la factibilidad de usar la biota nativa para su activación y así lograr la restauración de los monumentos biodeteriorados.

Published: December 2015

Pathogenicity of methicillin-resistant Staphylococcus aureus (MRSA) is associated with a broad spectrum of virulence factors, amongst which is α-hemolysin. The aim of this study was to investigate the effect of three newly-synthesized chalcones (1,3- Bis-(2-hydroxy-phenyl)-propenone, 3-(3-Hydroxy-phenyl)-1-(2-hydroxy-phenyl)-propenone and 3-(4-Hydroxy-phenyl)-1-(2-hydroxy-phenyl)-propenone) on α-hemolysin production of clinical isolates of MRSA. Subinhibitory concentrations of the tested compounds reduced hemolytic activity of MRSA strains, with almost complete abolishment of hemolysis at concentrations in the range of 1/2-1/4 x MIC (25-12.5 μg/ml). In conclusion, newly-synthesized chalcones tested in this study showed potent inhibitory activity on α-hemolysin production of multiresistant and genetically diverse MRSA strains.

Authors: Kozińska Monika , Augustynowicz-Kopeć Ewa
Published: December 2015

In total, 1095 Mycobacterium tuberculosis clinical isolates from 282 patients with drug-resistant and 813 with drug-sensitive tuberculosis (TB) in Poland during 2007–2011 were analysed. Seventy-one (6.5%) patients were found to have strains of Beijing genotype as defined by spoligotyping. The majority of patients were Polish–born; among foreign-born a large proportion came from Chechnya and Vietnam. Analysis showed strong associations between Beijing genotype infection and MDR, pre-XDR and XDR resistance, with a considerable relative risk among new patients, suggesting that this is due to increased spread of drug-resistant strains rather than acquisition of resistance during treatment.
Un singe à Cythère : Verlaine et la fête galante
Authors: Mullier Sébastien
Published: December 2015

Banville déclarait dans Odes funambulesques : « Il ne serait pas impossible d’imaginer une nouvelle langue comique versifiée, appropriée à nos moeurs et à notre poésie actuelle, et qui procéderait du véritable génie de la versification française en cherchant dans la rime elle-même ses principaux moyens comiques. » De la peinture de Watteau à sa critique d’art, notre ambition est de montrer comment, pour Verlaine, cette entreprise anachronique et donc ironique qu’est la composition d’une fête galante en plein xixe siècle s’inscrit dans la continuité d’un art identifié comme spécifiquement français et spirituel, mais aussi d’un genre humoristique des arts décoratifs : de Watteau et du xviiie siècle, Verlaine a peut-être moins pris pour modèle la fête galante que la singerie, cette peinture grotesque et rocaille où abondent singes musiciens, singes peintres et singes funambules. En plaçant le singe lascif de « Cortège » au centre d’une étude de Fêtes galantes, nous tentons d’étudier comment Verlaine a rêvé la pratique de la versification française comme la gestuelle comique, équivoque et sensuelle d’un singe funambule. Nous nous efforçons de définir les enjeux secrets de pratiques chères à un poète dont Lepelletier notait la physionomie « babouinesque » : certes la rime mais aussi l’autoparodie, cette manière de se singer soi-même. Nous inscrivons le parti rocaille de Fêtes galantes dans un débat historique contre le modèle hugolien et romantique des héritiers de 1793 : nous érigeons ainsi le singe verlainien en figure du fondement de l’Art pour l’Art, ce qu’Edgar Poe avait appelé « principe poétique ».
L’aporie lyrique du comique
Authors: Bernadet Arnaud
Published: December 2015

L’un des couples épistémologiques régulièrement invoqué dans la critique littéraire est le rapport entre le « lyrique » et le « comique ». Pourtant présentés comme fondateurs dans l’histoire et la théorie modernes du poème, ces termes constituent peut-être moins un instrument heuristique qu’un véritable lieu commun. L’objectif de cet article est de mettre à l’étude quelques-uns des présupposés qui entourent la notion de « lyrique » en usage dans l’analyse comique du texte poétique. Car entre le « lyrique » et le « comique », c’est le second qui est souvent l’élément marqué, tandis que le premier ressortit plutôt au donné. D’un côté, en soulignant ses composantes pragmatiques et esthétiques, le comique engage une conception résolument hybride et polyphonique du texte ; de l’autre, le lyrique indexe une représentation éclectique, ambiguë, sinon stéréotypée du phénomène poétique.
Fcp1 phosphatase controls Greatwall kinase to promote PP2A-B55 activation and mitotic progression
Authors: Della Monica Rosa , Visconti Roberta , Cervone Nando , Serpico Angela Flavia , Grieco Domenico
Published: December 2015

During cell division, progression through mitosis is driven by a protein phosphorylation wave. This wave namely depends on an activation-inactivation cycle of cyclin B-dependent kinase (Cdk) 1 while activities of major protein phosphatases, like PP1 and PP2A, appear directly or indirectly repressed by Cdk1. However, how Cdk1 inactivation is coordinated with reactivation of major phosphatases at mitosis exit still lacks substantial knowledge. We show here that activation of PP2A-B55, a major mitosis exit phosphatase, required the phosphatase Fcp1 downstream Cdk1 inactivation in human cells. During mitosis exit, Fcp1 bound Greatwall (Gwl), a Cdk1-stimulated kinase that phosphorylates Ensa/ARPP19 and converts these proteins into potent PP2A-B55 inhibitors during mitosis onset, and dephosphorylated it at Cdk1 phosphorylation sites. Fcp1-catalyzed dephosphorylation drastically reduced Gwl kinase activity towards Ensa/ARPP19 promoting PP2A-B55 activation. Thus, Fcp1 coordinates Cdk1 and Gwl inactivation to derepress PP2A-B55, generating a dephosphorylation switch that drives mitosis progression.
Trapping of injection charges in emission centers of GaN:Eu red LED characterized with 1/f noise involved in forward current
Authors: Ishii Masashi , Koizumi Atsushi , Fujiwara Yasufumi
Published: December 2015

Noise analysis of the forward current of LEDs was performed to identify the rate-limiting process of a recently developed Eu-doped GaN (GaN:Eu) red LED. Although the noise power spectrum of conventional InGaN blue and AlGaInP amber LEDs followed Poisson distributions, that of the GaN:Eu red LED indicated a 1/f noise. The Poisson distribution that represents electron–hole (e–h) recombination was consistent with the light emitting process of the conventional LED. On the other hand, the 1/f noise revealed that the rate-limiting process of the GaN:Eu LED was trapping of injection charges rather than following e–h recombination to excite Eu. From the detailed analysis of the 1/f noise, several emission centers with different trapping time constants (>3.5 ns) were discovered. These results demonstrated the applicability of the noise analysis to characterization of charge dynamics in the new LEDs.

The process controllability of inductively coupled plasma-enhanced reactive sputter deposition for the fabrication of amorphous InGaZnO
x
(a-IGZO) channel thin-film transistors (TFTs) was investigated. a-IGZO film deposition with the addition of H2 gas was performed using a plasma-assisted reactive sputtering system to control the oxidation process during a-IGZO film formation by balancing the oxidation and reduction reactions. Optical emission spectroscopy measurements indicate the possibility for the oxidation reaction to be inhibited by a decrease in the density of oxygen atoms and the reduction effect of hydrogen during a-IGZO film deposition due to the addition of H2 gas. The characteristics of TFTs fabricated using a-IGZO films deposited with a plasma-enhanced magnetron sputtering deposition system were investigated. The results indicate the possibility of expanding the process window by controlling the balance between oxidation and reduction with the addition of H2 gas. TFTs with a-IGZO films that were deposited with the addition of H2 gas exhibited good performance with a field-effect mobility (μFE) of 15.3 cm2 V−1 s−1 and a subthreshold gate voltage swing (S) of 0.48 V decade−1.

Published: December 2015

Zinc-oxide (ZnO) nanorod arrays were successfully prepared by using dual sonication sol–gel process. Field emission scanning electron microscopy revealed that the nanorods exhibited a hexagonal structure with a flat-end facet. The nanorods displayed similar surface morphologies and grew uniformly on the seed layer substrate, with the average diameter slightly increasing to the range of 65 to 80 nm after being immersed for varying growth times. Interestingly, thickness measurements indicated that the thicknesses of the samples increased as the growth time was extended. In addition, the X-ray diffraction spectra indicated that the prepared ZnO nanorods with a hexagonal wurtzite structure grew preferentially along the c-axis. Therefore, we can conclude that the diameter, length, and orientation of the ZnO nanorod arrays along the c-axis are controllable by adjusting the growth time, motivating us to further explore the growth mechanisms of ZnO nanorods.
Characteristics of an atmospheric-pressure line plasma excited by 2.45 GHz microwave travelling wave
Authors: Suzuki Haruka , Nakano Suguru , Itoh Hitoshi , Sekine Makoto , Hori Masaru , Toyoda Hirotaka
Published: December 2015

An atmospheric-pressure line plasma was produced by microwave discharge using a slot antenna with travelling microwave power. Two different types of plasma mode, i.e., “pseudo” and “real” line plasma were investigated using a high-speed camera under different discharge conditions, such as slot gap width and power. Using wide slot gaps (0.5 mm) and low powers (<1.0 kW), the pseudo line plasma mode, i.e., the time-averaged line plasma mode with the fast movement of small plasmas along the slot, was observed. By reducing the slot gap width to 0.1 mm and by increasing the peak microwave power, the plasma mode changed from the pseudo to real line plasma mode, i.e., the spatiotemporally uniform plasma mode along the slot. A gas temperature was obtained from N2 second positive band spectra as low as 400 K. The movement of the plasma in the pseudo line plasma mode was well explained by a one-dimensional diffusion model including the spatial distribution of the ionization rate in a moving plasma.
Electroless plating of Ni thin films using foam of electrolyte
Authors: Furuhashi Takahiro , Yamada Yoshiyasu , Ichihara Shoji , Takai Akihiro , Usui Hiroaki
Published: December 2015

Electroless plating of Ni thin films was achieved in foam of electroplating solution in place of electroplating liquid. Commercial hypophosphite-based solution for Ni electroless plating was added with a surfactant of sulfuric acid monododecyl ester sodium salt (SDS) and bubbled with nitrogen gas to produce airy foam. Ni thin films were deposited by immersing iron substrates in the foam. Although stationary foam was inconvenient for electrodeposition by itself, film growth was enhanced by generating a flow of foam using substrate rotation and by adding SDS to a concentration of 0.1 to 0.3 wt %. No defects attributed to pinholes were observed on the film surface. This method was effective in reducing the net amount of plating solution necessary for film deposition.
Modeling the ecologic niche of plague in sylvan and domestic animal hosts to delineate sources of human exposure in the western United States
Authors: Walsh Michael , Haseeb MA
Published: December 2015

Plague has been established in the western United States (US) since 1900 following the West Coast introduction of commensal rodents infected withYersinia pestisvia early industrial shipping. Over the last century, plague ecology has transitioned through cycles of widespread human transmission, urban domestic transmission among commensal rodents, and ultimately settled into the predominantly sylvan foci that remain today where it is maintained alternatively by enzootic and epizootic transmission. While zoonotic transmission to humans is much less common in modern times, significant plague risk remains in parts of the western US. Moreover, risk to some threatened species that are part of the epizootic cycle can be quite substantive. This investigation attempted to predict the risk of plague across the western US by modeling the ecologic niche of plague in sylvan and domestic animals identified between 2000 and 2015. A Maxent machine learning algorithm was used to predict this niche based on climate, altitude, land cover, and the presence of an important enzootic species,Peromyscus maniculatus. This model demonstrated good predictive ability (AUC = 86%) and identified areas of high risk in central Colorado, north-central New Mexico, and southwestern and northeastern California. The presence ofP. maniculatus, altitude, precipitation during the driest and wettest quarters, and distance to artificial surfaces, all contributed substantively to maximizing the gain function. These findings add to the known landscape epidemiology and infection ecology of plague in the western US and may suggest locations of particular risk to be targeted for wild and domestic animal intervention.
Analysis of synonymous codon usage patterns in sixty-four different bivalve species
Authors: Gerdol Marco , De Moro Gianluca , Venier Paola , Pallavicini Alberto
Published: December 2015

Synonymous codon usage bias (CUB) is a defined as the non-random usage of codons encoding the same amino acid across different genomes. This phenomenon is common to all organisms and the real weight of the many factors involved in its shaping still remains to be fully determined. So far, relatively little attention has been put in the analysis of CUB in bivalve mollusks due to the limited genomic data available. Taking advantage of the massive sequence data generated from next generation sequencing projects, we explored codon preferences in 64 different species pertaining to the six major evolutionary lineages in Bivalvia. We detected remarkable differences across species, which are only partially dependent on phylogeny. While the intensity of CUB is mild in most organisms, a heterogeneous group of species (including Arcida and Mytilida, among the others) display higher bias and a strong preference for AT-ending codons. We show that the relative strength and direction of mutational bias, selection for translational efficiency and for translational accuracy contribute to the establishment of synonymous codon usage in bivalves. Although many aspects underlying bivalve CUB still remain obscure, we provide for the first time an overview of this phenomenon in this large, commercially and environmentally important, class of marine invertebrates.

In a general way, micro and small enterprises (MPEs) are attractive for their rentability, but, because of some deficiencies in short term financial administration, they work in a high risk of bankruptcy. In this context, this paper aimed to identify and analyze the acting of strategical groups of MPEs according to the methodologies and practices in the working capital conduction, taking as reference the city of Viçosa, MG. In this paper, in which it was used the exploratory quantitive approach, 172 MPEs proprietors were interviewed, and this fact, through the factorial analyses followed by the cluster analyses, enables the identification of three groups with distincts characteristics, basing in restrictive aspects of risk of bankruptcy in these enterprises: low risk, medium risk, and high risk. Despite of the fact that it was noticeable a low risk of bankruptcy group, it is evident the importance of the short term financial administration in the region studied, since the maintenance of a correct administration is far from being unannimous because of the classification of nearly 30% of the enterprises in medium and high risk of bankruptcy groups. To finish, the identification of the enterprises with similar strategies and the best practices used in the short term financial administration can be an aplication instrument in the enterprises classified in medium and high risk of bankruptcy, since some conditioning factors of the risk of bankruptcy were identified.

The modern factoring began their activities in Brazil in the decade of 1980, with the proposal of aiding the small entrepreneur with the purchase of credits, assuming risks, and the installment of other several support services. Therefore, it became an option to reduce the financial costs, of breach of contract and, even, managerial of their customers. This exploratory research was developed with the main objective of verifying nowadays, in practice, the performance of the factoring companies brings benefits to the small enterprises, through the reduction of the costs. The studied universe was bounded to the graphs located in Great Rio, justified for treating of a segment of the sector of larger performance of the factorings (the industry) and the sample was no probabilistic, defined for accessibility. The results revealed that most of the consulted enterprises don’t have access to the support services that should be being offered by the factorings. They just offer the provision of resources, without assumption of risks for the debtor's breach of contract and with higher costs than the operations made by the financial institutions.

A APRENDIZAGEM ORGANIZACIONAL SOB A PERSPECTIVA SÓCIO-COGNITIVA: CONTRIBUIÇÕES DE LEWIN, BANDURA E GIDDENS
Authors: Freitas Sandra Ferreira , Godoi Christiane Kleinübing
Published: December 2015

This article seeks to establish the transfer of contributions of socio-cognitive learning theories to the sphere of organizational learning. The central argument is the idea that social cognition explains organizational learning more adequately than the fragmented studies of learning derived from the organizational field. Within the socio-cognitive perspective, organizational learning is understood as the result of a reciprocal exchange between socio-cognitive constructs and organizational culture. The understanding of organizational learning requires consideration of the social aspects of learning, and is based on theories capable of interconnecting individual processes, the functioning of the groups, and social relations. Among the learning theories that consider the social context, we elect the analysis and transfer of the following theories, to the organizational sphere: a) Kurt Lewin’s field theory (and his influence on Dewey); b) Bandura’s cognitive social learning theory (and the influence of the attribution theory); and Giddens’ theory of structuration.

This paper presents the results about voluntary disclosure of social and environmental Intellectual Capital (IC) in the 2006 Annual Reports and Sustainability Reports (henceforth, Annual Reports – ARs), and on the websites of the 39 companies that are listed on the "In Good Company" program of the São Paulo Stock Market (BOVESPA). The purpose of this study is to identify how the disclosure of both types of IC is performed and what elements are most frequently disclosed by the companies assessed. To perform the analysis, two matrices containing IC elements were designed – one for social IC, and another for environmental IC. This is a descriptive study, based on data from a secondary source, employing content analysis. The results indicate that environmental elements tended to be disclosed more frequently than social elements. Among the environmental IC elements, the most recurrent category was Internal Structure, both in the reports and on the websites. The same category is the most frequent in the social analysis of the reports; conversely, External Structure was the social IC category with the highest percentages of disclosure on the websites.

Under the eyes of the present, this paper analyzes the pioneerism of Brazilian retail enterprises in the incorporation of e-commerce to existent activities. The following aspects are researched: the evolution of virtual businesses, the new organizational structure created to support the e-commerce activities, the impacts on the organization structure generated by these activities in the study cases and the enterprise position in front of virtual business analysis and comprehension models. The right and wrong ways, advances and retrocession are discussed based on three study cases which are analyzed under two theoretical models. It could be observed that the main difficulty still remains how to transform “bits” in “atoms”.

The information is vital for ensuring harmony among the constituent parts of the capital market. The value of the information, the knowledge’s base, is recognized and appreciated by all in the contemporary world. While each individual has his own interpretation, access to it is imperative for a more efficient and fair functioning of markets. One way to providing information to the market is through the policy of dividends. According to the argument of the theory of signaling, the policy of dividend form a channel of communication, where administrators will provide signals that could mitigate the asymmetry of information. This paper notes that dynamic by testing the importance of dividends communication. Based on the methodology created by Fama and French, were showed that the evolution of dividends in Brazil is opposed to the U.S. and England. Because in the brazilian’s market is not noted a decline as in other countries.

In this paper, we combine active and passive source P wave seismic data to tomographically image the magmatic system beneath Newberry Volcano, located east of the Cascade arc. By using both travel times from local active sources and delay times from teleseismic earthquakes recorded on closely spaced seismometers (300–800 m), we significantly improve recovery of upper crustal velocity structure (<10 km depth). The tomographic model reveals a low‐velocity feature between 3 and 5 km depth that lies beneath the caldera, consistent with a magma body. In contrast to earlier tomographic studies, where elevated temperatures were sufficient to explain the recovered low velocities, the larger amplitude low‐velocity anomalies in our joint tomography model require low degrees of partial melt (∼10%), and a minimum melt volume of ∼2.5 km3. Furthermore, synthetic tests suggest that even greater magnitude low‐velocity anomalies, and by inference larger volumes of magma (up to 8 km3), are needed to explain the observed waveform variability. The lateral extent and shape of the inferred magma body indicates that the extensional tectonic regime at Newberry influences the emplacement of magmatic intrusions. Our study shows that jointly inverting active source and passive source seismic data improves tomographic imaging of the shallow crustal seismic structure of volcanic systems and that active source experiments would benefit from longer deployment times to also record teleseismic sources.
Global MHD modeling of resonant ULF waves: Simulations with and without a plasmasphere

We investigate the plasmaspheric influence on the resonant mode coupling of magnetospheric ultralow frequency (ULF) waves using the Lyon‐Fedder‐Mobarry (LFM) global magnetohydrodynamic (MHD) model. We present results from two different versions of the model, both driven by the same solar wind conditions: one version that contains a plasmasphere (the LFM coupled to the Rice Convection Model, where the Gallagher plasmasphere model is also included) and another that does not (the stand‐alone LFM). We find that the inclusion of a cold, dense plasmasphere has a significant impact on the nature of the simulated ULF waves. For example, the inclusion of a plasmasphere leads to a deeper (more earthward) penetration of the compressional (azimuthal) electric field fluctuations, due to a shift in the location of the wave turning points. Consequently, the locations where the compressional electric field oscillations resonantly couple their energy into local toroidal mode field line resonances also shift earthward. We also find, in both simulations, that higher‐frequency compressional (azimuthal) electric field oscillations penetrate deeper than lower frequency oscillations. In addition, the compressional wave mode structure in the simulations is consistent with a radial standing wave oscillation pattern, characteristic of a resonant waveguide. The incorporation of a plasmasphere into the LFM global MHD model represents an advance in the state of the art in regard to ULF wave modeling with such simulations. We offer a brief discussion of the implications for radiation belt modeling techniques that use the electric and magnetic field outputs from global MHD simulations to drive particle dynamics.
The impact of wave‐induced Coriolis‐Stokes forcing on satellite‐derived ocean surface currents
Authors: Hui Zhenli , Xu Yongsheng
Published: December 2015

Ocean surface currents estimated from the satellite data consist of two terms: Ekman currents from the wind stress and geostrophic currents from the sea surface height (SSH). But the classical Ekman model does not consider the wave effects. By taking the wave‐induced Coriolis‐Stokes forcing into account, the impact of waves (primarily the Stokes drift) on ocean surface currents is investigated and the wave‐modified currents are formed. The products are validated by comparing with OSCAR currents and Lagrangian drifter velocity. The result shows that our products with the Stokes drift are better adapted to the in situ Lagrangian drifter currents. Especially in the Southern Ocean region (40°S–65°S), 90% (91%) of the zonal (meridional) currents have been improved compared with currents that do not include Stokes drift. The correlation (RMSE) in the Southern Ocean has also increased (decreased) from 0.78 (13) to 0.81 (10.99) for the zonal component and 0.76 (10.87) to 0.79 (10.09) for the meridional component. This finding provides the evidence that waves indeed play an important role in the ocean circulation, and need to be represented in numerical simulations of the global ocean circulation.

Objective

To systematically compare the risk of adverse events (AEs) for 13 targeted immunomodulators (TIMs) indicated for ankylosing spondylitis (AS), inflammatory bowel diseases, juvenile idiopathic arthritis, plaque psoriasis, psoriatic arthritis (PsA), or rheumatoid arthritis (RA).

Methods

We searched electronic databases through July 2015 to retrieve randomized controlled trials (RCTs) and observational studies comparing AEs between 2 or more TIMs head‐to‐head. We reported on the following outcomes: number of AEs, discontinuation due to AEs, serious AEs, mortality, serious infections, tuberculosis, herpes zoster, and malignancies. We qualitatively synthesized the literature and conducted random‐effects meta‐analyses if 3 or more studies provided data for an outcome.

Results

Ten head‐to‐head RCTs and 51 observational studies were included in this systematic review. A majority of the studies (70%) were conducted in RA patients. Risk of treatment discontinuation due to AEs was higher with infliximab than with adalimumab or etanercept in RA, PsA, and AS. A higher risk for serious infections was noted with infliximab than with abatacept, adalimumab, or etanercept in RA. Risk for treatment discontinuation due to AEs, serious infections, and tuberculosis was lower with etanercept than with adalimumab in RA. Limited evidence suggested no comparative differences in risk for mortality, malignancies, and herpes zoster for adalimumab, etanercept, and infliximab in RA.

Conclusion

Important differences were noted in the safety profile of TIMs in RA, generally favoring abatacept, adalimumab, and etanercept over infliximab. Head‐to‐head comparative evidence for other TIMs and non‐RA populations was insufficient to draw conclusions for most of the safety outcomes.
