Microsserviços / Microservices

Uma das propriedades de um ser vivo é a evolução, com o passar do tempo basicamente tudo se modifica e evolui. Assim como Darwin teorizava, o ser vivo precisa se adaptar e evoluir, caso o contrário, ele é extinto. No mundo do desenvolvimento de software essa teoria ocorre de forma similar. Com o passar dos anos novas metodologias, ferramentas e tecnologias vão surgindo para facilitar a construção e a manutenção dos sistemas além de tornar as características funcionais e não funcionais mais atrativas e usuais para o cliente. A arquitetura monolítica dominou o mercado por vários anos, porém, com o passar do tempo, foram sendo evidenciados os problemas que acompanhavam essa arquitetura. Nesse cenário, a arquitetura de microsserviços entra como uma evolução natural, sendo uma abordagem alternativa que visa a diminuição de acoplamento do código, da organização e da independência dos serviços (Módulos que possuem funções próprias). Nesse artigo, foram levantados os pontos principais que indicam o valor agregado gerado pela implementação dos microsserviços, quais os desafios relacionados a sua implementação e resultados obtidos por grandes empresas ao implementar essa arquitetura. Para chegar em tais resultados foram feitas pesquisas e análises sistemáticas de documentos e relatórios inerentes aos resultados, riscos e custos relacionados ao tema.

Efficiency in the use of phosphorus by cowpea genotypes

Cowpea (Vigna unguiculata (L.) Walp.) is an edible legume with good ability to fix nitrogen and not demanding soil fertility. However, some genotypes may have a greater ability to utilize the nutrients available in the soil for their growth. Thus, the objective of this work was to evaluate the efficiency of phosphorus (P) use in genotypes of cowpea. The experiment was conducted in the field and the experimental design was a randomized complete block design with four replicates arranged in a 2 x 5 factorial scheme. The treatments consisted of two P doses (0 and 60 kg ha-1 of P2O5) and five bean genotypes (Paulistinha, BRS Xiquexique, Pingo de Ouro, Corujinha, and Costela de Vaca). Each plot was formed by four plant rows, measuring 3.0 m in length, spaced 1.0 x 0.3 m, and with two plants per hole. The genotypes responded significantly to the increase in P levels in the soil, with increases in the number of seeds per pod, number of pods per plant, productivity, dry mass, and plant P accumulation. "BRS Xiquexique" was efficient and responsive, and it could be indicated as the most appropriate for cultivation in the region. "Corujinha" is the most suitable cultivar for production in high levels of P among the creole genotypes evaluated. "Costela de Vaca" and "Paulistinha" can be indicated for low P production in the soil. low P production

Neuroproteção na ressecção cirúrgica de gliomas cerebrais: revisão da evidência atual

Os gliomas cerebrais são tumores primários do sistema nervoso central que se desenvolvem a partir de células gliais e têm alta morbimortalidade. Seu tratamento padrão envolve a ressecção cirúrgica, radioterapia e quimioterapia, os quais possivelmente podem levar os pacientes a um prognóstico desfavorável. Nesse contexto, a neuroproteção entra como uma aliada para minimizar os efeitos colaterais da ressecção cirúrgica e melhorar a sobrevida e a qualidade de vida dos pacientes. Nesse sentido, o presente estudo tem como objetivo discutir sobre a evidência atual da neuroproteção na ressecção cirúrgica de gliomas cerebrais. Para isso, foram selecionados quatro artigos que que abordavam sobre a evidência atual da neuroproteção na ressecção cirúrgica de gliomas cerebrais, por meio de uma estratégia de busca com recorte temporal entre 2014 e 2023, nas bases de dados PubMed (Medline), Embase e Cochrane Library. Os resultados indicam que o grupo de pacientes que recebeu dexmedetomidina apresentou melhora significativa na cognição e redução da inflamação cerebral em comparação com o grupo-controle pós-ressecção dos gliomas cerebrais, além de menor incidência de efeitos colaterais anestésicos, como náusea e vômitos (p < 0,05). Ademais, foi observado que a modulação da via metabólica do glutamato/glutamina pode inibir o crescimento de gliomas e proteger o parênquima cerebral. Nesse sentido, as evidências atuais indicam que proteger as células nervosas é uma estratégia importante para minimizar os efeitos colaterais da ressecção cirúrgica de gliomas cerebrais, e a dexmedetomidina e a co-cultura de células de glioma e astrócitos que aumenta a concentração extracelular de glutamato e glutamina parecem ser importantes aliadas nessa profilaxia

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

A retrospective investigation was undertaken to describe clinical, epidemiological, and viral genomic features associated with deaths caused by CHIKV in Ceará state, northeast Brazil. METHODS: Sera, cerebrospinal fluid (CSF), and tissue samples from 100 fatal cases with suspected arbovirus infection were tested for CHIKV, dengue virus (DENV), and Zika virus (ZIKV). Clinical, epidemiological, and death reports were obtained for patients with confirmed CHIKV infection. Logistic regression analysis was undertaken to identify independent factors associated with risk of death during CHIKV infection. Phylogenetic analysis was conducted using whole genomes from a subset of cases. RESULTS: Sixty-eight fatal cases had CHIKV infection confirmed by reverse-transcription quantitative polymerase chain reaction (52.9%), viral antigen (41.1%), and/or specific immunoglobulin M (63.2%). Co-detection of CHIKV with DENV was found in 22% of fatal cases, ZIKV in 2.9%, and DENV and ZIKV in 1.5%. A total of 39 CHIKV deaths presented with neurological signs and symptoms, and CHIKV-RNA was found in the CSF of 92.3% of these patients. Fatal outcomes were associated with irreversible multiple organ dysfunction syndrome. Patients with diabetes appear to die at a higher frequency during the subacute phase. Genetic analysis showed circulation of 2 CHIKV East-Central-South African (ECSA) lineages in Ceará and revealed no unique virus genomic mutation associated with fatal outcome. CONCLUSIONS: The investigation of the largest cross-sectional cohort of CHIKV deaths to date reveals that CHIKV-ECSA strains can cause death in individuals from both risk and nonrisk groups, including young adults. © The Author(s) 2020.
