Política educacional: identidade latinoamericana e descentralização
Authors: Leite Roseana Costa 
Published: July 2021

Esta comunicação tem por objetivo apresentar para discussão um projeto de pesquisa, que pretendo desenvolver como parte das atividades de pós-doutorado, na expectativa de encontrar interlocutores.
Neste momento, minha atenção volta-se às perguntas assinaladas pelos movimentos sociais, à necessidade de praticar uma abertura nos limites da ciência eurocêntrica e da construção de uma cosmovisão alternativa ao ideário neoliberal. A pergunta central refere-se à democratização da política educacional e, nesta discussão, a participação da sociedade civil e as formas de participação direta. Para tanto pretendo examinar a sociologia latinoamericana para estudar a questão da identidade latinoamericana, a partir do conceito de ressentimento social, e a participação social e popular. Esta parte dos estudos pretende representar uma contribuição à discussão a respeito do multiculturalismo e educação. Outro ponto de meu interesse refere-se à questião da descentralização das políticas públicas, no contexto da reforma do estado no atual proceso de reestruturação capitalista, e de seu par complementar a globalização. O suposto é de que a descentralização é una estratégia para limitar la transnacionalização da ação política.

Published: July 2021

Estudo sobre as relações entre Estado e escola no Brasil, o âmbito da participação nas políticas educacionais e a gestão democrática em três eixos: efetividade, possibilidade e necessidade. Por meio do materialismo histórico dialético destacamos que a educação veiculada em todo o mundo como direito de todo homem e como passaporte para a sua riqueza a partir da década de 1990, ascendeu como especial atenção em meio ao modo-de-produção capitalista, como alternativa unilinear de solidarização econômica, social e política, de modo particular nas políticas educacionais do Brasil, inicialmente no governo de Fernando Henrique Cardoso e tendo continuidade no governo petista de Luís Inácio Lula da Silva por meio de suas projeções de participação popular anunciadas e listadas Plano Plurianual (PPA) 2004-2007, consistindo numa gestão democrática consentida. Este movimento de esvaziamento do político, com conseqüente fortalecimento de resultados pragmáticos, a exemplo do mercado, mudou a o foco da centralidade do poder decisório, do coletivo para o autocrático e também o reducionismo dos movimentos populares e sociais, instituindo na escola canais legítimos de participação (conselhos, associações de pais e mestres, constituinte escolar, dentre outros) ritmados pelo ideário da reprodução capitalista.

Targeting Class IIa HDACs: Insights from Phenotypes and Inhibitors
Authors: Liu Ligong , Dong Lilong , Bourguet Erika , Fairlie David P. 
Published: July 2021

:
This review summarizes key literature defining the phenotypes of individual class
IIa HDAC proteins and compounds that selectively target their enzymatic catalytic domain
(CD). The focus is on the effects of class IIa HDACs in physiological and pathological conditions,
both in vitro and in vivo, and on their mode of action in regulating genes, upstream proteins
and signaling pathways. Phenotype studies further demonstrate either beneficial or detrimental
effects of silencing selected class IIa HDACs or their enzymatic properties. We also
summarize the knowledge gained from structure-activity relationships of CD inhibitors as
well as molecular mechanisms underpinning isozyme selectivity where crystal structures or
modelling studies are available. Given that the number of genes affected by silencing class IIa
HDACs is much smaller than class I, the role of gene regulation of class IIa HDACs could be
much more selective. Since class IIa HDACs have restricted tissue distributions and multiple
functions independent of their CD, targeting the CD of class IIa HDACs could lead to more
selective therapeutic agents with significantly fewer side-effects than other HDAC ligands.
High Fat Diet Aggravates AD-Related Pathogenic Processes in APP/PS1 Mice
Authors: Gong Xiaokang , Liang Zheng , Liu Wei , Zhao Yang , Yang Youhua , Wu Mengjuan , Shang Jinting , Xiao Yifan , Mei Yong , Su Qiqi , Sun Binlian , Bao Jian , Shu Xiji 
Published: July 2021

Background:
Alzheimer’s disease (AD) is the most common neurodegenerative disorder
and negative lifestyle factors may contribute to its etiopathogenesis. Substantial evidence from
humans and murine models reveals that Insulin Resistance (IR) associated with a high fat diet
(HFD) increases the risk of developing AD and age-related amyloidogenesis.

Objective:
The aim of the study was to corroborate and clarify the influence of HFD on amyloidogenesis
and cognitive deficits in AD model mice.

Methods:
We here show that a four months HFD-feeding increases IR in both the periphery and
brain of APP/PS1 mice, which are used as AD models. Meanwhile, long-term HFD exacerbates
cognitive defects and impairs dendritic integrity and expressions of synaptic proteins in APP/PS1
mice. Furthermore, HFD induces an increase in β-secretase (BACE1) expression and a decrease in
insulin-degrading enzyme (IDE) expression, resulting in β-amyloid (Aβ) accumulation.

Conclusion:
Our data suggest that long-term HFD, with the accompanying IR, promotes Aβ toxicity
and cognitive deficits, indicating that modifiable lifestyle hazards such as HFD-induced IR
might contribute to AD pathogenesis.
A Preliminary Nuclear Magnetic Resonance Metabolomics Study Identifies
Metabolites that Could Serve as Diagnostic Markers of Major Depressive
Disorder
Authors: Badamasi Ibrahim Mohammed , Maulidiani Maulidiani , Lye Munn Sann , Ibrahim Normala , Shaari Khozirah , Stanslas Johnson 
Published: July 2021

Background:
The evaluation of metabolites that are directly involved in the physiological
process, few steps short of phenotypical manifestation, remains vital for unravelling the biological
moieties involved in the development of the (MDD) and in predicting its treatment outcome.

Methodology:
Eight (8) urine and serum samples each obtained from consenting healthy controls
(HC), twenty-five (25) urine and serum samples each from first episode treatment naïve MDD
(TNMDD) patients, and twenty (22) urine and serum samples each s from treatment naïve MDD patients
2 weeks after SSRI treatment (TWMDD) were analysed for metabolites using proton nuclear
magnetic resonance (1HNMR) spectroscopy. The evaluation of patients’ samples was carried out
using Partial Least Squares Discriminant Analysis (PLS-DA) and Orthogonal Partial Least Square-
Discriminant Analysis (OPLSDA) models.

Results:
In the serum, decreased levels of lactate, glucose, glutamine, creatinine, acetate, valine, alanine,
and fatty acid and an increased level of acetone and choline in TNMDD or TWMDD irrespective of
whether an OPLSDA or PLSDA evaluation was used were identified. A test for statistical validations of
these models was successful.

Conclusion:
Only some changes in serum metabolite levels between HC and TNMDD identified in
this study have potential values in the diagnosis of MDD. These changes included decreased levels of
lactate, glutamine, creatinine, valine, alanine, and fatty acid, as well as an increased level of acetone
and choline in TNMDD. The diagnostic value of these changes in metabolites was maintained in samples
from TWMDD patients, thus reaffirming the diagnostic nature of these metabolites for MDD.
Bronchial Thermoplasty for Severe Asthma: From Past to Present and Future
Authors: Bilaçeroğlu Semra 
Published: July 2021

Background:
Approximately 3-10% of all asthmatics are refractory with severe disease,
although they use optimal preventive treatment. This is reflected as a disproportionate increase in
the cost of health care. Thus, bronchial thermoplasty has been developed as an add-on therapy for
these refractory asthmatics.

Objective:
This review aims to give an update on bronchial thermoplasty in severe asthma regarding
pathophysiological mechanisms of action, patient selection, procedural details, history, evidence-
based effectiveness, safety and cost-effectiveness, place in management, and challenges in
current clinical practice.

Methods:
A thorough search for the eligible and recent studies and reviews on bronchial thermoplasty
and asthma has been conducted in PubMed.

Results:
In bronchial thermoplasty, radiofrequency energy delivered to bronchial airway walls
leads to ablation of the airway smooth muscles that cause bronchoconstriction. Several large trials
and a real-world study confirm its safety, and effectiveness, as shown by considerable reduction in
asthma exacerbations, emergency department visits and hospitalizations as well as improvement in
asthma-related quality of life, maintained up to 5 years. These improvements are more significant
in more severe airway obstruction. Bronchial thermoplasty is more cost-effective if hospitalization
and emergency department care cost high, but the procedure costs low. Properly performed patient
identification, implementation and follow-up are critical for successful and safe outcomes with the
procedure.

Conclusion:
A 10-year research and clinical experience has proved the long-term safety, and effectiveness
of bronchial thermoplasty for improving asthma control and quality of life in severe asthma.
Predictors of response (e.g. biomarkers, responder endotype/phenotype) remain to be studied
further and better qualified.
IoT Solutions for Smart Management of Hospital Buildings: A General Review towards COVID-19, Future Pandemics, and Infectious Diseases
Authors: Akbarzadeh Omid , Baradaran Mehrshid , Khosravi Mohammad R. 
Published: July 2021

Background:
The paper aims to review existing solutions for smart building to increase
hospitality levels in locations like hospitals. The answers could support features such as online appointments,
smart navigation, and queue management in the building through mobile phone and navigation
to the desired location by highlighting the point of interest and facilities and checking the
spaces' occupancy.

Methods:
Such a solution addresses all mentioned issues regarding the smart building by integrating
and utilizing various data sources collected by the internet of things (IoT) sensors. This solution
mainly deals with location determining, also known as positioning, using Bluetooth Low Energy radio.
The goal is to implement a low-power, low-cost indoor positioning system that utilizes existing
hardware.

Results:
Positions determining is considered a significant section of these kinds of solutions. Previous
attempts with indoor positioning systems intensify statistical fingerprinting methods, mainly using
IEEE 802.11 (WLAN) as the platform.

Conclusion:
Some efforts have been made with purely signal strength-based positioning, but indoor
environments have been shown to work inauspiciously for these kinds of methods.
Co Nanoparticles Decorated MoS2 Nanosheets Grown on Reduced Graphene Oxide as Cathode Catalyst for Li-air Batteries
Authors: Chen Lihong , Liu Chenyu , Yuan Mengwei , Liu Rong , Shi Keren , Ma Shulan 
Published: July 2021

Background:
Li-air batteries have attracted huge attention in recent years due to the ultrahigh
theoretical specific energy. The development of high-performance and low-cost cathode
electrocatalysts for Li-air batteries is of great importance and has faced great challenges.

Objective:
This study aimed to design a new kind of cathode catalyst material for Li-air batteries.

Methods:
In this study, MoS2-rGO-Co was fabricated through a hydrothermal treatment following a
chemical reduction process. A series of characterizations, including XRD, SEM, Raman, and XPS,
were employed to explore the structure, morphology, and composition information of MoS2-rGOCo.
The performance and stability of the MoS2-rGO-Co-based Li-air battery were tested in electrochemical
measurements.

Results:
A composite of Co nanoparticles decorated flower-like MoS2 nanosheets grown on reduced
graphene oxide (rGO), denoted as MoS2-rGO-Co, was successfully prepared. The MoS2-rGO-Cobased
Li-air battery showed superior electrochemical performance with a capacity of 6591 mAh g-1,
a reduced overpotential of ~500 mV, and enhanced cycling stability.

Conclusion:
Through a combination of hydrothermal method and chemical reduction, the hybrid
cathode catalyst of MoS2-rGO-Co was successfully synthesized, which exhibited great electrochemical
performance and stability in the Li-air battery. The high electrocatalytic activity of the composite
benefits from the synergistic effect of MoS2 and Co as well as the rGO substrate, in which the
high conductivity substrate provides the efficient electron transfer channel and the optimized electron
structure of active components improves the electrocatalytic activity in battery reaction. All
these advantages make great contributions to the superior performance of Li-air batteries. Our strategy
paves a new way for exploring excellent electrocatalysts applied to other energy fields.
The Unified Medical Language System at 30 Years and How It Is Used and Published: Systematic Review and Content Analysis
Authors: Jing Xia 
Published: July 2021

Background
The Unified Medical Language System (UMLS) has been a critical tool in biomedical and health informatics, and the year 2021 marks its 30th anniversary. The UMLS brings together many broadly used vocabularies and standards in the biomedical field to facilitate interoperability among different computer systems and applications.

Objective
Despite its longevity, there is no comprehensive publication analysis of the use of the UMLS. Thus, this review and analysis is conducted to provide an overview of the UMLS and its use in English-language peer-reviewed publications, with the objective of providing a comprehensive understanding of how the UMLS has been used in English-language peer-reviewed publications over the last 30 years.

Methods
PubMed, ACM Digital Library, and the Nursing & Allied Health Database were used to search for studies. The primary search strategy was as follows: UMLS was used as a Medical Subject Headings term or a keyword or appeared in the title or abstract. Only English-language publications were considered. The publications were screened first, then coded and categorized iteratively, following the grounded theory. The review process followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines.

Results
A total of 943 publications were included in the final analysis. Moreover, 32 publications were categorized into 2 categories; hence the total number of publications before duplicates are removed is 975. After analysis and categorization of the publications, UMLS was found to be used in the following emerging themes or areas (the number of publications and their respective percentages are given in parentheses): natural language processing (230/975, 23.6%), information retrieval (125/975, 12.8%), terminology study (90/975, 9.2%), ontology and modeling (80/975, 8.2%), medical subdomains (76/975, 7.8%), other language studies (53/975, 5.4%), artificial intelligence tools and applications (46/975, 4.7%), patient care (35/975, 3.6%), data mining and knowledge discovery (25/975, 2.6%), medical education (20/975, 2.1%), degree-related theses (13/975, 1.3%), digital library (5/975, 0.5%), and the UMLS itself (150/975, 15.4%), as well as the UMLS for other purposes (27/975, 2.8%).

Conclusions
The UMLS has been used successfully in patient care, medical education, digital libraries, and software development, as originally planned, as well as in degree-related theses, the building of artificial intelligence tools, data mining and knowledge discovery, foundational work in methodology, and middle layers that may lead to advanced products. Natural language processing, the UMLS itself, and information retrieval are the 3 most common themes that emerged among the included publications. The results, although largely related to academia, demonstrate that UMLS achieves its intended uses successfully, in addition to achieving uses broadly beyond its original intentions.
Relatos visuales en tiempos de crisis: transferencias culturales y apropiaciones políticas en las crónicas festivas
Authors: Salazar Baena Verónica 
Published: July 2021

Este artículo aborda las transferencias culturales y la apropiación política de la cultura visual en los territorios de la monarquía hispánica. Para tal fin, se utilizan las fuentes documentales emanadas de las celebraciones con ocasión del nacimiento de los príncipes Baltazar Carlos (1631) y Carlos II (1663), celebraciones que tuvieron lugar en Quito, importante centro urbano del norte andino, y Pamplona, en el nororiente del Nuevo Reino de Granada, respectivamente. Si bien estas fuentes son textuales y carecen de representaciones gráficas, consideramos que la característica principal de estas crónicas festivas es que son generadoras de visualidad a partir de la textualidad, razón por la cual funcionan como un relato visual también conocido como écfrasis. En estecaso en concreto, se trata de un relato visual construido por los encomenderos con la intención de reivindicar su rol en un contexto de especial conflicto con las autoridades imperiales.

Published: July 2021

Abstract In this work we present the growth and characterization of GaAs self-assembled quantum wires (SAQWRs), and InAs self-assembled quantum dots (SAQDs) by molecular beam epitaxy on (631)-oriented GaAs substrates. Adatoms on the (631) crystal plane present a strong surface diffusion anisotropy which we use to induce preferential growth along one direction to produce SAQWRs. On the other hand, InAs SAQDs were obtained on GaAs(631) with SAQWRs by the Stransky–Krastanov (S-K) growth method. SAQDs grown directly on (631) substrates presented considerable fluctuations in size. We study the effects of growing a stressor layer before the SAQDs formation to reduce these fluctuations.Keywords : Quantum wires, quantum dots; selfassembly; molecular beam epitaxy.
