Análisis iconográfico de las obras pictóricas de la época colonial en Guatemala (Siglos del XVI al XVIII), expuestas en el museo de arte colonial de Antigua Guatemala.
Authors: Mariana Mariana Aracely 
Published: December 2019

El arte colonial Guatemalteco surge, gracias a la constante relación de los pobladores del entonces nuevo continente con aquellos provenientes del continente europeo, esto propicio los intercambios artísticos-culturales, abriendo así una nueva posibilidad de desarrollo artístico de la sociedad, lo que se ve reflejado en los avances de las bellas artes en la época, en la implementación, perfeccionamiento e interpretación de la escultura, arquitectura y pintura, incluso en la creación de talleres con artistas nacionales.
El objetivo principal de la investigación fue desarrollar, una lectura iconográfica de las pinturas más representativas de la época de la colonia en Guatemala, comprendida del siglo XVI al XVIII y que en la actualidad se exhiben en el museo de Arte colonial de Antigua Guatemala, creando un catálogo de las obras y así contribuir con los esfuerzos de documentar el arte nacional y la creación de bibliografía, con la cual se pueda guiar a los interesados en llevar a cabo lecturas iconográficas de obras pictoricas.
Para colocar en contexto a cualquier persona que tenga acceso a la investigación, sea experta o no en arte se cuenta con un primer capítulo con toda la información básica sobre pintura, una cronología general de las tendencias a lo largo de la historia, sus posibles composiciones, técnicas y su relación con la religión. Se agrega un marco legal, pues los saqueos a los que se ha visto expuesto el patrimonio Guatemalteco y las dificultades experimentadas en el proceso para obtener acceso a las piezas estudiadas, nos obliga a conocer más la legislación que debería garantizar la protección de estas obras artísticas. Como cuarto paso se crea un contexto histórico, para colocar en sintonía al lector, sobre lo que sucedía en el momento de la creación de las obras, y como todo esto influía directamente en el arte y los temas a representar. En el quinto capítulo encontramos la catalogación de las pinturas, agrupándolas en primer lugar por autores, luego en ciclos pictóricos o temas en común y por último la secuencia o cronología que puedan tener principalmente los ciclos, es a partir de este orden que se lleva a cabo la lectura iconográfica de cada pieza, diagramando las láminas en las cuales se presenta cada obra en tres partes, pre-iconografía, que consiste en la descripción general de la obra, Iconografía, donde se ubican, identifican y describen los personajes que integran la pintura, quienes son y sus principales atributos y por último la Iconología, que es donde se realiza una interpretación de la obra de acuerdo a la historia, el contexto histórico y la simbología encontrada dentro de la obra. Por ultimo a partir de toda la información incluida en las lecturas, se crea un resumen de la simbología encontrada en las piezas en un formato de glosario iconográfico, y que podrá ser útil para futuras lecturas.
“RECORDAR É PODER”: ESTRATÉGIAS DE UMA MEMÓRIA FAMILIAR DISTINTA EM CENTENÁRIAS FAZENDAS DO CARIRI PARAIBANO
Authors: Meneses Valdênio Freitas 
Published: December 2019

O artigo propõe analisar estratégias que envolvem usos da memória familiar associada a centenárias fazendas na região do Cariri Paraibano. Utilizando do exemplo das fazendas Capitão-Mor e Pitombas da família Fernandes Batista é possível analisar como, em um contexto de transformações sociais recentes, parte de uma elite rural sob ameaça de desprestígio transformou patrimônios materiais e simbólicos. Esse tema é próximo a um debate no campo de estudos das reconversões sociais, estratégias de mudança e permanência sobre capitais econômicos, culturais e simbólicos. São analisadas duas estratégias da família Fernandes Batista: uma parte dos livros de memória que destacam a escolarização de duas gerações da família. Já outra estratégia trata da conservação do patrimônio material tornando as fazendas – outrora espaços de produção econômica em museus e arquivos, ou seja, locais de memória e culto e nostalgia de uma ordem social pecuarista passada.

Authors: Lara de Siqueira João Paulo , Telles Renato , M. Queiroz Maciel , Yoshihiro Hamaji Edison , Gomes Ferreira Gabriel 
Published: December 2019

Objective of the study: This study aims to investigate the characteristics of the networks of volleyball teams in Brazilian context, in amateur and professional level.Methodology/Approach: This research adopted an interpretive paradigm, in which six Brazilian volleyball teams were studied. The techniques of data collection were qualitative and encompassed interviews, analysis of information available in the press and on websites and observation.Originality/Relevance: Prior literature has not investigated in-depth with the lens of the networks theory, the sports organizations at an amateur and professional level, considering the firms’ life cycle. To address this gap, considering that, similar to the life cycle of firms, amateurism and professionalism are specific strategic contexts.Main results: Our findings indicated that actor’s of team’s networks could be divided into two groups, one linked to sports and other to administrative activities. Additionally, teams’ networks have in common the fact that paid team members perform activities related to the sport itself.Theoretical/Methodological contributions: The fact that Superliga B has more collaborations obtained by personal contacts, while Superliga A teams build a more calculated network, meet the propositions made in this study and are aligned to the general idea of the work of Hite and Hesterly (2001) about changes in firm’s network and firm’s life cycle. Social contribution/for management: The main implications for management indicated that, whether companies or volleyball teams, should align their networks with the current life cycle stage. If a volleyball team plans to become professional, it should be aware of the need to adapt the network to a new division.

Published: December 2019

Background
Traumatic brain injury (TBI) is a common neurological emergency observed in hospitals. A considerable number of patients suffer from long-term disabilities after TBI. This study aimed to identify altered gene expression signatures and mechanisms related to TBI-induced chronic neuroinflammation and neurodegeneration.

Methods
An integrated analysis was performed using published RNA-sequencing studies to determine TBI-induced differentially expressed genes (DEGs). Based on the DEG data, functional annotation, signal-net, and transcription factor analyses were conducted to understand the mechanism of chronic neuroinflammation and neurodegeneration induced after TBI.

Results
Two datasets were obtained using the Gene Expression Omnibus database, of which, 6,513 DEGs were identified (6,464 upregulated and 49 downregulated). Positive regulation of biological process, positive regulation of cellular process, nucleus, and heterocyclic compound binding were Gene Ontology terms significantly enriched in post-TBI rat models. Leukocyte transendothelial migration, chemokine signaling pathway, neurotrophin signaling pathway, and longevity-regulating pathway were significantly enriched after TBI. With regard to the signal-net analysis, FOXO3, DGKZ and ILK were considered the most critical genes derived using high–betweenness centrality calculation. A total of 44 TFs, including FOXO1, SRY and KLF4, were predicted to play an important role in the upregulation of gene expression. Using integrated bioinformatics analysis, TBI was found to be associated with a significant inflammatory response and neurodegeneration. FOXO3, apolipoprotein (APOE), microtubule-associated protein tau (MAPT), and TREM2 were probably associated with the TBI pathological process. The mitochondrial electron transport chain may be associated with neurodegeneration in patients with TBI, serving as a potential therapeutic target.

Background: Nine out of every 10 of the world’s 1.8 billion adolescents and young people (AYP) live in developing nations, Nigeria inclusive. In Nigeria as in the rest of sub-Saharan Africa, 1 out of every 3 persons is an adolescent or a young person. As at 2016, there were about 240, 000 AY) aged 10-19 years in Nigeria, which roughly makes 7% of the total number of people living with HIV (PLWH) in Nigeria. According to 2017 national survey, about 70% of the country’s AYP lack knowledge of how HIV is transmitted or how it can be prevented. Since AYP, aged 10-19 years, constitute a significant proportion of the nation’s burgeoning population, it is very important and critical to fully understand the dynamics of the HIV epidemic among AYP. This study aimed at determining the prevalence of HIV among AYP at a tertiary health facility in Ekiti State, Southwest Nigeria and comparing it with national and regional prevalence among same group.
Methodology: The study was a retrospective study of AYP, aged 13-20 years at Ekiti State University Teaching Hospital, Ado-Ekiti, Ekiti State, Southwest Nigeria. Convenience and consecutive sampling method was used in retrieving subjects’ data. One hundred subjects whose ages were between 13 and 20 years were consecutively sampled over a period of six months, July to December, 2018.
Results: Out of the one hundred subjects retrospectively sampled, 46 (46%) were males, while 54 (54%) were females. Four (4%) of the subjects were 13 years of age, while 6(6%), 5(5%), 8(8%), 27(27%), 17(17%), 12(12%) and 21(21%) respectively were aged 14, 15, 16, 17, 18, 19 and 20 years. Three (3%) of the subjects were positive to HIV, 1 (%) was male, while 2 (20%) were female, thus giving a sero-prevalence rate of 3%. Disaggregation of the positive subjects reveals that 33.3% were male, while 66.7% were females.
Conclusion: Though the general prevalence of HIV in Ekiti State ranks among the lowest in Nigeria, group-specific interventions targeting the AYP should be put in place in the State to address the disproportionately high prevalence among the AYP in the State.
Mitotic cyclin Clb4 is required for the intracellular adaptation to glucose starvation in Saccharomyces cerevisiae

Published: December 2019

Cellular homeostasis in response to glucose availability is maintained through the tight coordination of various physiological processes, including cell proliferation, transcription, and metabolism. In this study, we use the budding yeast Saccharomyces cerevisiae to identify proteins implicated in carbon source‐dependent modulation of physiological processes. We find that the mitotic cyclin Clb4 is required for optimal regulation of glucose‐starvation‐responsive pathways through the target of rapamycin complex 1. Cells lacking Clb4 are characterized by dysregulation of autophagy and impaired modulation of cell size. Notably, cell viability after prolonged glucose starvation is severely reduced by disruption of Clb4. We conclude that Clb4, in addition to its function in the cell cycle, plays a role in the intracellular adaptation to glucose starvation.

Published: December 2019

AbstractObjectiveFriedreich ataxia (FRDA) is the commonest hereditary ataxia in Caucasians. Most patients are homozygous for expanded GAA triplet repeats in the first intron of the frataxin (FXN) gene, involved in mitochondrial iron metabolism. Here, we used magnetoencephalography (MEG) to characterize the main determinants of FRDA‐related changes in intrinsic functional brain architecture.MethodsFive minutes of MEG signals were recorded at rest from 18 right‐handed FRDA patients (mean age 27 years, 9 females; mean SARA score: 21.4) and matched healthy individuals. The MEG connectome was estimated as resting‐state functional connectivity (rsFC) matrices involving 37 nodes from six major resting state networks and the cerebellum. Source‐level rsFC maps were computed using leakage‐corrected broad‐band (3–40 Hz) envelope correlations. Post hoc median‐split was used to contrast rsFC in FRDA patients with different clinical characteristics. Nonparametric permutations and Spearman rank correlation test were used for statistics.ResultsHigh rank correlation levels were found between rsFC and age of symptoms onset in FRDA mostly between the ventral attention, the default‐mode, and the cerebellar networks; patients with higher rsFC developing symptoms at an older age. Increased rsFC was found in FRDA with later age of symptoms onset compared to healthy subjects. No correlations were found between rsFC and other clinical parameters.ConclusionAge of symptoms onset is a major determinant of FRDA patients' intrinsic functional brain architecture. Higher rsFC in FRDA patients with later age of symptoms onset supports compensatory mechanisms for FRDA‐related neural network dysfunction and position neuromagnetic rsFC as potential marker of FRDA neural reserve.

Published: December 2019

AbstractDeveloping highly effective and stable counter electrode (CE) materials to replace rare and expensive noble metals for dye‐sensitized and perovskite solar cells (DSC and PSC) is a research hotspot. Carbon materials are identified as the most qualified noble metal‐free CEs for the commercialization of the two photovoltaic devices due to their merits of low cost, excellent activity, and superior stability. Herein, carbonaceous CE materials are reviewed extensively with respect to the two devices. For DSC, a classified discussion according to the morphology is presented because electrode properties are closely related to the specific porosity or nanostructure of carbon materials. The pivotal factors influencing the catalytic behavior of carbon CEs are also discussed. For PSC, an overview of the new carbon CE materials is addressed comprehensively. Moreover, the modification techniques to improve the interfacial contact between the perovskite and carbon layers, aiming to enhance the photovoltaic performance, are also demonstrated. Finally, the development directions, main challenges, and coping approaches with respect to the carbon CE in DSC and PSC are stated.

Published: December 2019

AbstractMicroplasmas are low‐temperature plasmas that feature microscale dimensions and a unique high‐energy‐density and a nonequilibrium reactive environment, which makes them promising for the fabrication of advanced nanomaterials and devices for diverse applications. Here, recent microplasma applications are examined, spanning from high‐throughput, printing‐technology‐compatible synthesis of nanocrystalline particles of common materials types, to water purification and optoelectronic devices. Microplasmas combined with gaseous and/or liquid media at low temperatures and atmospheric pressure open new ways to form advanced functional materials and devices. Specific examples include gas‐phase, substrate‐free, plasma‐liquid, and surface‐supported synthesis of metallic, semiconducting, metal oxide, and carbon‐based nanomaterials. Representative applications of microplasmas of particular importance to materials science and technology include light sources for multipurpose, efficient VUV/UV light sources for photochemical materials processing and spectroscopic materials analysis, surface disinfection, water purification, active electromagnetic devices based on artificial microplasma optical materials, and other devices and systems including the plasma transistor. The current limitations and future opportunities for microplasma applications in materials related fields are highlighted.

AbstractA synthetic method to prepare cycloalkyl‐ and (hetero)aryl‐fused bicyclo[3.3.1]nonane derivatives from gold(I)‐catalyzed cyclopropanation/[5+3] cycloaddition of 1,4,9‐ and 1,4,10‐allenenynes is described. The suggested double cycloisomerization mechanism delineates the first example of a stepwise [5+3] cycloaddition pathway in gold catalysis, a mode of reactivity that is also sparse in organic chemistry. Experimental and Density Functional Theory (DFT) computational studies based on a proposed gold carbenoid species provides insight into this unique selectivity that leads to the assembly of the architecturally challenging bridged carbocyclic motif.magnified image

BackgroundChronic rhinosinusitis (CRS) is one of the most common causes of olfactory loss, but the pathophysiology underlying olfactory dysfunction in CRS has not been fully elucidated. Previous studies found correlations between olfactory cleft (OC) inflammatory cytokines/chemokines and olfaction in CRS. The purpose of this study was to evaluate the relationship between OC mucus inflammatory proteins and olfaction in a multi‐institutional cohort.MethodsAdults with CRS were prospectively recruited. Demographics, comorbidities, olfactory assessment (Sniffin’ Sticks), computed tomography (CT), and OC mucus for protein analysis were collected. Statistical analysis was performed to determine associations between olfactory function, OC mucus protein concentrations, and CT opacification.ResultsSixty‐two patients were enrolled in the study, with an average age of 48.2 (standard deviation, 16.2) years, and 56.5% were female and 59.7% were classified as CRS with nasal polyps (CRSwNP). Ten of 26 OC mucus proteins were significantly correlated with threshold, discrimination, and identification (TDI) scores and OC opacification. Subgroup analysis by polyp status revealed that, within the CRSwNP group, C‐C motif ligand 2 (CCL2), interleukin‐5 (IL‐5), IL‐6, IL‐13, IL‐10, IL‐9, tumor necrosis factor‐α (TNF‐α), CCL5, and CCL11 were significantly correlated with olfaction. For CRS without nasal polyps (CRSsNP), only C‐X‐C ligand 5 (CXCL5) showed a correlation. In CRSwNP, IL‐6, IL‐10, vascular endothelial growth factor‐A, and immunoglobulin E (IgE) correlated with OC opacification, whereas, in CRSsNP, only CXCL5 showed a correlation. OC mucus proteins and Lund‐Mackay score correlated only in the CRSsNP group (CXCL5, IL‐5, IL‐13, IgE).ConclusionSeveral OC mucus proteins have been found to correlate with olfactory function and OC opacification. The profile of OC mucus proteins differs between CRSsNP and CRSwNP subgroups, suggesting different mechanisms between groups, but further study is required.
Synthesis and characterization of triarylamine‐based polyimides for electrochromic and optoelectronic conversion behaviors
Authors: Cai Shuwei , Niu Haijun 
Published: December 2019

ABSTRACTIn this study, four novel triarylamine‐based polyimides with different substituted groups (tert‐butyl and ‐H) containing pyrrole moieties were successfully prepared by polycondensation reaction. The electrochemical and electrochromic properties of the polyimides were measured by cyclic voltammetry and spectro‐electrochemistry. The polyimides exhibited obvious electrochromic behavior with good thermal stability (the 10% weight‐loss temperatures were recorded in the range of 345‐386°C), film‐forming ability and reversible stability after 1000 s. The color of the polyimide films changed from colorless to light blue or yellow to blue on increasing the applied potential. The highest coloration efficiency reached up to 190 cm2C−1. The polyimide films exhibited a stable response to the light (on or off) after 200 s. Especially, PyHBTPI displayed effective solubility, superior optical contrast (~30%) in the visible region, faster response time (1.19 s for coloring process), and obvious color change from yellow to blue with good stability, thus, confirming the potential use for high contrast displays. Overall, the study demonstrates the successful development of high‐performance polyimides for electrochromic and optoelectronic behaviors. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.
