ANÁLISE MOLECULAR, BIOLÓGICA E FILOGENÉTICA DO NOVO CORONAVÍRUS SARS-COV-2
Authors: Pereira Rordana Gomes Fernandes , Queiroz Paulo Roberto Martins
Published: November 2021

Introdução: Os coronavírus são uma família de vírus que possuem RNA de fita simples e são capazes de contaminar homens e animais. São conhecidos por sua alta frequência de recombinação e altas taxas de mutação, permitindo que se adaptem a novos hospedeiros e nichos ecológicos. Os níveis virais elevados fornecem um ambiente adequado para a replicação viral, levando a persistência viral, por sua vez, pode originar novas estirpes virais. Objetivo: O objetivo deste trabalho foi analisar o aspecto molecular, biológico e filogenético do SARS-CoV-2. Material e Métodos: Para isso, foi feito um levantamento dos estudos relacionados com o tema ao longo dos anos de 2019 e 2021 e a utilização de vários softwares para a análise filogenética de 105 genomas completos do SARS-Cov-2 provenientes do Brasil, China, Índia, Itália e Estados Unidos e de morcegos de Wuhan (WIV). Resultados: Apenas duas sequências do SARS-Cov-2 isolados no Brasil tiveram semelhança com as sequências WIV, demonstrando que as estirpes brasileiras da pesquisa possuem uma alta variabilidade genética. Já os isolados do SARS-Cov-2 isolados na China apresentam o maior número de sequências relacionadas com as WIV. Nos isolados virais da Índia observou-se uma relação de afinidade por um ancestral comum e os isolados WIV, porém, não possuem uma similaridade direta com as sequências WIV pois a análise mostrou mais ramificações isoladas confirmando achados de estudos que revelaram que a Europa e o Sudeste Asiático são as duas principais rotas de introdução da doença na Índia. Os vírus dos Estados Unidos, da China e da Índia ficaram reunidos com as estirpes do próprio país demostrando através do alinhamento de sequências que mutações diferentes ocorrem pelo mundo. Além disso, algumas estirpes apresentaram proximidade com outras sequências de outros países devido a circulação de pessoas entre as nacionalidades estudadas neste trabalho. Conclusão: O novo Coronavírus foi originado de um processo de coevolução com início em um animal não humano e atingiu os hospedeiros humanos através do salto de espécies. Dessa forma, com base na filogenia molecular do genoma viral essa capacidade zoonótica traz consigo o alerta para possíveis novos surtos ou epidemias devido à evolução e adaptações desse vírus em outros hospedeiros animais.
CITOGENÉTICA E A RELAÇÃO DO EXERCÍCIO FÍSICO NO COMPRIMENTO DOS TELÔMEROS
Authors: Rodrigues Gabriela , Silva Nathalia Maria Barbosa Da , Carvalho Rafael Leite Carvalho
Published: November 2021

Introdução: O projeto foi idealizado para servir de apoio e responder as perguntas já existentes na literatura, servindo de referência atualizada sobre o assunto. Com isso trazendo uma revisão mais completa sobre a importância da realização de atividade física, na proporção adequada, mostrando-se capaz de desacelerar os efeitos naturais do envelhecimento e aprimorar o perfil imunológico geral. Objetivos: Consta-se em base na análise de dados selecionados, esse projeto de pesquisa tem como objetivo encontrar a causa do comprimento dos telômeros, seja por estresse oxidativo ou estilo de vida. Material e Métodos: Foram usadas palavras chaves para a realização do levantamento dos artigos que foram combinadas de distintas formas no banco de dados dos sites PubMed, Google Acadêmico e Scielo. Os artigos escolhidos foram sendo registrados em uma planilha para em seguida, ser possível fazer a relação entre os artigos selecionados. Resultados: Foram revisadas diversas bibliografias a respeito da morfologia cromossômica, senescência celular e o impacto do exercício físico no comprimento dos telômeros. Após a revisão, os resultados obtidos confirmaram que há uma grande relação, sobretudo benéfica, entre o exercício físico e o estresse oxidativo. Indivíduos que praticam atividade física regularmente, tendem a manter uma maior defesa antioxidante das células, o que não causa atrito telomérico, e consequentemente, o encurtamento dos telômeros. O estresse oxidativo diminui o tempo de vida do indivíduo por encurtar a região cromossômica, sinalizando à célula a morte celular. Porém, ainda há diversos resultados para serem alcançados, pois a pesquisa ainda está em andamento. Conclusão: Sabe-se que os telômeros são conhecidos como a chave do envelhecimento, pensando em nível celular temos o conhecimento que estão situados nas extremidades dos cromossomos cujo sua principal função é realizar a proteção do material genético impedindo assim que o mesmo fique exposto e fazendo com que em cada replicação não ocorra o “problema de replicação final” pois nas extremidades do cromossomo que estão localizados os telômeros.
ASSOCIAÇÃO ENTRE A OBESIDADE E ABORTOS DE EMBRIÕES EUPLOIDES
Authors: Heimbecker Vivian
Published: November 2021

Introdução: A obesidade é definida pela apresentação de um índice de massa corporal (IMC) ≥ 30 kg/m². É considerada uma doença crônica associada a doenças cardiovasculares, diabetes tipo 2 e câncer, por exemplo, levando a maiores taxas de morbidade e mortalidade. Quanto à relação com a fertilidade, tem-se que homens e mulheres obesos apresentam menores taxas de concepção. Também nas mulheres, a obesidade contribui para menores taxas de implantação oocitária, gravidez e números de nascidos vivos por fertilização in vitro (FIV). Objetivos: Explorar a literatura a respeito da associação entre abortos euploides e a obesidade feminina. Material e métodos: Trata-se de uma revisão de literatura de artigos em língua inglesa das bases de dados PubMed e Biblioteca Virtual em Saúde (BVS) publicados nos últimos 10 anos. Outro critério de inclusão adotado foi apresentar os termos “obesity”, “euploid” e “miscarriage” no título ou resumo. Foram excluídos trabalhos que não seguiram os critérios anteriores. Resultados: Perda de gravidez recorrente de embrião euploide é vinculada a polimorfismos de genes de susceptibilidade múltipla e fatores de estilo de vida, como idade, hábito de fumar e obesidade. Abortos no primeiro trimestre de gestação normalmente são atribuídos a embriões aneuploides, entretanto, abortos euploides foram relacionados ao IMC em pacientes que passaram por algum procedimento de FIV e Teste Genético Pré-Implantacional para Aneuploidias (PGT-A). Mulheres magras (IMC 18,5 – 24,9 kg/m²) apresentaram menores taxas de aborto (14%) do que as com sobrepeso (29%) ou obesas (42%). Entre as obesas, também houve chance 56% maior de aborto euploide do que em mulheres não obesas. Conclusão: A partir dos resultados, conclui-se que mulheres obesas sofrem mais abortos do que as não obesas. Também é possível inferir que abortos ligados à obesidade podem não ter uma causa genética. Há pouca informação relacionando a perda de peso à prevenção do aborto.

Este artículo muestra que la economía salvadoreña posee, desde el punto de vista macroeconómico, factores positivos, como un crecimiento económico moderado, una tasa de inflación baja en relación con otros países, una solvencia externa favorable, dado el alto nivel de reservas internacionales, etc., pero desde el punto de vista de bienestar económico de la población, los resultados no son compatibles con el comportamiento macroeconómico; en varios aspectos nuestra economía muestra señales de desigualdad: el estancamiento del sector agropecuario, la caída del poder de compra de los trabajadores que devengan el salario mínimo, una estructura impositiva regresiva, una distribución desigual del ingreso, etc. Esta situación obliga a pensar en políticas económicas que ayuden a combatir de manera más efectiva el fenómeno de la pobreza.

En este artículo, la autora expone el surgimiento, el desarrollo y la influencia de un modo de construir e interpretar la realidad para transformarla, que si bien se nutre de otras corrientes, pretende generar una respuesta propia, que se inserte en el desarrollo de un paradigma que presenta características específicas en América Latina. Tal desarrollo supone una ontología o concepción del ser; una epistemología, o modo preferente de relación entre el sujeto cognoscente y el objeto conocido; una metodología, es decir, las vías para construir ese conocimiento; una posición ética, en cuanto supone una peculiar relación con el otro y una posición política, puesto que dichas dimensiones afectan a la sociedad y la ciudadanía.

La concentración de la actividad económica en El Salvador
Authors: Montoya Aquiles
Published: November 2021

La estructura de la mayor parte de la actividad económica de El Salvador está sumamente concentrada. El objetivo principal de este artículo es demostrar que la concentración estadístico-estructural conlleva a una concentración del ingreso, lo cual a su vez origina mercados raquíticos que impiden el crecimiento de la economía en cuanto a generación de empleo e ingresos suficientes que abatan la pobreza. Por tanto, es urgente y necesario mejorar la distribución del ingreso para posibilitar un crecimiento endógeno y autosostenido.

Pyruvic acid, an efficient catalyst in SO3 hydrolysis and effective clustering agent in sulfuric acid-based new particle formation
Authors: Tsona Tchinda Narcisse , Du Lin , Liu Ling , Zhang Xiuhui
Published: November 2021

Abstract. The role of pyruvic acid (PA), one of the most abundant α-keto carboxylic acids in the atmosphere, was investigated both in the SO3 hydrolysis reaction to form sulfuric acid (SA) and in SA-based aerosol particle formation using quantum chemical calculations and a cluster dynamics model. We found that the PA-catalyzed SO3 hydrolysis is a thermodynamically driven transformation process, proceeding with a negative Gibbs free energy barrier, ca. −1 kcal mol−1 at 298 K, ~6.50 kcal mol−1 lower than that in the water-catalyzed SO3 hydrolysis. Results indicated that the PA-catalyzed reaction can potentially compete with the water-catalyzed SO3 reaction in SA production, especially in dry and polluted areas, where it is found to be ~two orders of magnitude more efficient that the water-catalyzed reaction. Given the effective stabilization of the PA-catalyzed SO3 hydrolysis product as SA•PA cluster, we proceeded to examine the PA clustering efficiency in sulfuric acid-pyruvic acid-ammonia (SA-PA-NH3) system. Our thermodynamic data used in the Atmospheric Cluster Dynamics Code indicated that under relevant tropospheric temperatures and concentrations of SA (106 cm3), PA (1010 cm3) and NH3 (1011 and 5 × 1011 cm3), of the PA-containing clusters, only clusters with one PA molecule, namely (SA)2•PA•(NH3)2, can participate to the particle formation, contributing by ~100 % to the net flux to aerosol particle formation at 238 K, exclusively. At higher temperatures (258 K and 278 K), however, the net flux to the particle formation is dominated by pure SA-NH3 clusters, while PA would rather evaporate from the clusters at high temperatures and not contribute to the particle formation. The enhancing effect of PA of examined by evaluating the ratio of the ternary SA-PA-NH3 cluster formation rate to binary SA-NH3 cluster formation rate. Our results show that while the enhancement factor of PA to the particle formation rate is almost insensitive to investigated temperatures and concentrations, it can be as high as 4.7 × 102 at 238 K and [NH3] = 1.3 × 1011 molecule cm−3. This indicates that PA may actively participate in aerosol formation, only in cold regions of the troposphere and highly NH3-polluted environments. The inclusion of this mechanism in aerosol models may definitely reduce uncertainties that prevail in modeling the aerosol impact on climate.
Characterizing the dynamic movement of thunderstorms using VLF/LF total lightning data over the Pearl River Delta region
Authors: Cheng Si , Wang Jianguo , Cai Li , Zhou Mi , Huang Yijun , Su Rui , Li Quanxin
Published: November 2021

Abstract. This paper reveals the characteristics of thunderstorm dynamic movement using total lightning data obtained from the VLF/LF measurement. Eight thunderstorms, which was evenly distributed in the morning, midday, afternoon and evening, are selected to compare the different kinematic features around the Pearl River Delta (PRD) region in the south of China from 17 May to 23 May 2014. The connected-neighborhood labeling method is used to identify lightning clusters and obtain the centroids. Significant characterization parameters are put forward as metrics to reveal the kinematic features of thunderstorms, including the duration, valid area (VA), velocity, direction, and farthest distance in longitude and latitude during the life cycle of storm. A common trend is that the storms initiate in the west of the PRD region, moving to the east and disappearing after the thunderstorm travels around 106.5 km in longitude. There are two kinds of distribution to depict the property of valid area, which are one-peak distribution with the maximum in the mature stage and two-peak distribution with a relatively smaller peak in the early time of storm. The velocity does not show the same trend as the variation of VA which shows the steady increase or decrease during the lifetime of thunderstorm. The biggest VA and highest velocity are 891 km2 occurred on the evening of 17 May and 204.8 km h−1 occurred on the morning of 20 May. The 19 May evening storm was the weakest, with the maximum of VA and velocity being 253 km2 and 115.3 km h−1, respectively. The motion of storms shows a distinct pattern, as the spread of direction distributes tightly in the range of 0°–90° and 270°–360°. The movement characteristics of thunderstorm and the associated parameters may help to improve the nowcasting and forecasting system of thunderstorms in this region.
Ocean bubbles under high wind conditions. Part 1: Bubble distribution and development
Authors: Czerski Helen , Brooks Ian M. , Gunn Steve , Pascal Robin , Matei Adrian , Blomquist Byron
Published: November 2021

Abstract. The bubbles generated by breaking waves are of considerable scientific interest due to their influence on air-sea gas transfer, aerosol production, and upper ocean optics and acoustics. However, a detailed understanding of the processes creating deeper bubble plumes (extending 2–10 metres below the ocean surface) and their significance for air-sea gas exchange is still lacking. Here, we present bubble measurements from the HiWinGS expedition in the North Atlantic in 2013, collected during several storms with wind speeds of 10–27 m s−1. A suite of instruments was used to measure bubbles from a self-orienting free-floating spar buoy: a specialised bubble camera, acoustical resonators, and an upward-pointing sonar. The focus in this paper is on bubble void fractions and plume structure. The results are consistent with the presence of a heterogeneous shallow bubble layer occupying the top 1–2 m of the ocean which is regularly replenished by breaking waves, and deeper plumes which are only formed from the shallow layer at the convergence zones of Langmuir circulation. These advection events are not directly connected to surface breaking. The void fraction distributions at 2 m depth show a sharp cut-off at a void fraction of 10−4.5 even in the highest winds, implying the existence of mechanisms limiting the void fractions close to the surface. Below wind speeds of 16 m s−1 or RHw = 2 × 106, the probability distribution of void fraction at 2 m depth is very similar in all conditions, but increases significantly above either threshold. Void fractions are significantly different during periods of rising and falling winds, but there is no distinction with wave age. There is a complex near-surface flow structure due to Langmuir circulation, Stokes drift, and wind-induced current shear which influences the spatial distribution of bubbles within the top few metres. We do not see evidence for slow bubble dissolution as bubbles are carried downwards, implying that collapse is the more likely termination process. We conclude that the shallow and deeper bubble layers need to be studied simultaneously to link them to the 3D flow patterns in the top few metres of the ocean. Many open questions remain about the extent to which deep bubble plumes contribute to air-sea gas transfer. A companion paper (Czerski, 2021) addresses the observed bubble size distributions and the processes responsible for them.
Ocean bubbles under high wind conditions. Part 2: Bubble size distributions and implications for models of bubble dynamics
Authors: Czerski Helen , Brooks Ian M. , Gunn Steve , Pascal Robin , Matei Adrian , Blomquist Byron
Published: November 2021

Abstract. Bubbles formed by breaking waves in the open ocean influence many surface processes but are poorly understood. We report here on detailed bubble size distributions measured during the High Wind Speed Gas Exchange Study (HiWinGS) in the North Atlantic, during four separate storms with hourly averaged wind speeds from 10–27 m s−1. The measurements focus on the deeper plumes formed by advection downwards (at 2 m depth and below), rather than the initial surface distributions. Our results suggest that bubbles reaching a depth of 2 m have already evolved to form a heterogeneous but statistically stable population in the top 1–2 metres of the ocean. These shallow bubble populations are carried downwards by coherent near-surface circulations; bubble evolution at greater depths is consistent with control by local gas saturation, surfactant coatings and pressure. We find that at 2 m the maximum bubble radius observed has a very weak wind speed dependence and is too small to be explained by simple buoyancy arguments. For void fractions greater than 10−6, bubble size distributions at 2 m can be fitted by a two-slope power law (with slopes of −0.3 for bubbles of radius < 80 μm and −4.4 for larger sizes). If normalised by void fraction, these distributions collapse to a very narrow range, implying that the bubble population is relatively stable and the void fraction is determined by bubbles spreading out in space rather than changing their size over time. In regions with these relatively high void fractions we see no evidence for slow bubble dissolution. When void fractions are below 10−6, the peak volume of the bubble size distribution is more variable, and can change systematically across a plume at lower wind speeds, tracking the void fraction. Relatively large bubbles (80 μm in radius) are observed to persist for several hours in some cases, following periods of very high wind. Our results suggest that local gas supersaturation around the bubble plume may have a strong influence on bubble lifetime, but significantly, the deep plumes themselves cannot be responsible for this supersaturation. We propose that the supersaturation is predominately controlled by the dissolution of bubbles in the top metre of the ocean, and that this bulk water is then drawn downwards, surrounding the deep bubble plume and influencing its lifetime. In this scenario, oxygen uptake is associated with deep bubble plumes, but is not driven directly by them. We suggest that as bubbles move to depths greater than 2 m, sudden collapse may be more significant as a bubble destruction mechanism than slow dissolution, especially in regions of high void fraction. Finally, we present a proposal for the processes and timescales which form and control these deeper bubble plumes.
Tricentennial trends in spring ice breakups in three rivers in northern Europe

Abstract. In Finland, ice breakup observations have been recorded for centuries for Aura River (1749–2020), Torne River (1693–2020) and Kokemäki River (1793–2020). The Kokemäki River is a newly revised, extended, and updated ice breakup series from Pori. The Spearman analysis shows that the correlation between Aura and Kokemäki rivers is strong, while the correlation between the two southern rivers (Aura and Kokemäki) and Torne River is weaker. The difference is attributed to the longitudinal distance between the rivers. Temperature correlations are strong for all three rivers and the long-term trends towards earlier breakups are statistically significant. Aura and Kokemäki rivers show considerable changes. Aura and Kokemäki river have had two respectively three years without a complete ice cover in the 21st century. These are the first non-freeze events in over 270 years of recorded observations. In Torne River, however, the earliest recorded breakup date has changed only marginally the last 100 years. Moreover, the earliest recorded breakup date in the 21st century occurred only five days earlier than the earliest breakup date in the 18th century. Kokemäki River did not escape the hydroelectric power plant boom in the mid-1900s, and this has speeded up the breakup process. A qualitative analysis shows that exceptionally late ice breakups occurred in all three rivers in 1807, 1810 and 1867. There are noticeable clusters of late events in the early 1800s in all three series, while an exceptionally early breakup event occurred in Aura and Kokemäki rivers in 1822.
Future changes in North Atlantic winter cyclones in CESM-LENS. Part I: cyclone intensity, PV anomalies and horizontal wind speed
Authors: Dolores-Tesillos Edgar , Teubler Franziska , Pfahl Stephan
Published: November 2021

Abstract. Strong low-level winds associated with extratropical cyclones can cause substantial impacts on society. The wind intensity and the spatial distribution of wind maxima may change in a warming climate; however, the involved changes in cyclone structure and dynamics are unclear. Here, such structural changes of strong North Atlantic cyclones in a warmer climate close to the end of the current century are investigated with storm-relative composites based on Community Earth System Model Large Ensemble (CESM-LENS) simulations. Furthermore, a piecewise potential vorticity inversion is applied to associate such changes in low-level winds to changes in potential vorticity (PV) anomalies at different levels. Projected changes in cyclone intensity are generally rather small. However, using cyclone-relative composites, we identify an extended wind footprint southeast of the center of strong cyclones, where the wind speed tends to intensify in a warmer climate. Both an amplified low-level PV anomaly driven by enhanced diabatic heating and a dipole change in upper-level PV anomalies contribute to this wind intensification. On the contrary, wind changes associated with lower- and upper-level PV anomalies mostly compensate each other upstream of the cyclone center. Wind changes at upper levels are dominated by changes in upper-level PV anomalies and the background flow. All together, our results indicate that a complex interaction of enhanced diabatic heating and altered non-linear upper-tropospheric wave dynamics shape future changes in near-surface winds in North Atlantic cyclones.

As medidas de distanciamento social, em virtude da pandemia de  COVID-19, refletiram na dinâmica dos estabelecimentos de ensino em todo o mundo, dentre elas o fechamento de universidades. Nessa mesma ótica, o Brasil foi de encontro aos outros países, acarretando principalmente, ausência de aulas práticas nos cursos da área da saúde. Com isso, urge ressaltar que as universidades se organizem por meio dos protocolos de biossegurança para que a abertura e o retorno de aulas práticas se dê de forma segura de acordo com a epidemiologia de cada região. Logo, esse artigo aborda a problemática inserida na graduação do cursos da saúde na Universidade Federal de Jataí e propõe protocolos de biossegurança que podem ser implementados de acordo com a epidemiologia do município de Jataí-GO, o qual preza sempre, pela saúde  e segurança dos profissionais e estudantes da universidade a fim de garantir a segurança da comunidade acadêmica e a qualidade educacional.

O contexto epidemiológico vivenciado no município de Jataí é um espelho da epidemia da COVID-19 não só no estado de Goiás, como em todo o país. Inúmeros protocolos foram utilizados como medidas preventivas na tentativa de conter a COVID-19 no município, seguindo as recomendações do governo estadual. Algumas situações levantadas no artigo podem ter interferidos na curva epidemiológico da doença, como as eleições, feriados que resultaram em diminuição do isolamento social, decretos de abertura do comércio e a mudança da gestão municipal de 2020 a 2021. Todas essas questões foram levantadas e abordadas no presente artigo e analisadas de acordo com literaturas disponíveis. Pensando num possível cenário de retorno de atividades presenciais da Universidade Federal de Jataí, os prováveis cenários devem ser analisados de acordo com o contexto e curva epidemiológica da doença, para que possíveis previsões sejam realizadas e o delineamento dessa doença, seja o mais próximo possível do esperado.

Diante da pandemia da COVID-19, a suspensão de atividades presenciais no âmbito da educação foi necessária para promover medidas de prevenção contra essa enfermidade. Com a demanda de realizar isolamento social e a manutenção da educação, o ensino passou por muitas mudanças. Sendo assim, compreender a percepção dos alunos diante desse novo cenário de ensino-aprendizagem se faz necessário para avaliar as principais problemáticas enfrentadas. Diante disso, realizou-se revisão de literatura do tipo umbrella review, na qual foram analisadas matérias em veículos de mídias e 25 trabalhos na base PubMed, 20 no banco de dados Scielo e 62 artigos na BVS, desses, foram selecionados 11, 9 e 15, respectivamente. Os resultados demonstram que os empecilhos perpassam o campo das limitações de acesso à internet e tecnologias. Portanto, conhecer a realidade enfrentada pelos alunos mostra-se necessário para mitigar os impactos da pandemia na aprendizagem.
