- Abstract
The analysis and control of costs in the "San Angel" Livestock is of utmost importance, since it allows keeping an updated record of the amounts incurred in breeding, reproduction and milk production during the year 2021, in order to establish a reasonable price, which goes hand with the market demand and in turn implies economic benefits for the farmer. Our integrative project was born with the objective of analyzing and implementing the agricultural costs in the breeding, reproduction and production of bovine milk in the "San Angel" Livestock. For the case under study, a descriptive and applied research was carried out, through a mixed methodology, where initially data was obtained that facilitated the knowledge of the real costs of the different processes that have been implemented and the current state of the same, for the application of a cost system by processes, which allows to identify the critical points of the current management, and in turn recommend new processes to optimize resources and thus increase income. For this implementation, the cattle were classified in two stages: breeding and reproduction, and production, the first one includes the manger stage from 0 to 3 months, breeding from 3 to 18 months, and reproduction from 18 months of life, and in the second one, milk production, which starts from the first calving, that is, on average from 27 months of life. In the first chapter, the theoretical framework and the accounting regulations within the livestock activity were studied and analyzed, in the second chapter, information was gathered that allowed to know in depth the management system of the property and the livestock herd, and finally, in the third chapter, the cost model by processes was implemented according to the breeding, reproduction and milk production stages. Once the cost system was implemented, the economic results for the period 2021 were not favorable, however, from this the owner will be able to make appropriate and timely decis

- Abstract
This work was carried out for the species M. vaccinioides, D. ericoides, G. miniphylla and C. jussieui, of the Asteraceae family, present in the Zhurucay páramo, Azuay province. A batch of heads from 15 individuals was collected and the production of achenes (viable, non-viable, empty and infested) was analyzed at the species level. Morphological and quality characterization of the achenes was carried out from another general lot of heads from the populations distributed throughout the study area, and germination tests were carried out on this same lot, for which a design was applied. completely randomly independent for each collection season (factor 1), with two levels: high and low precipitation. In addition, the state of maturity (factor 2) was considered, with two levels: semi-mature and matured ex situ, with five repetitions of 50 seeds each. The number of achenes produced in the two collection seasons did not present significant differences for any species and all species presented low viability (<5%) and a high presence of empty achenes (19.97%-80%). In the case of C. jussieui, it showed greater infestation of larvae and pupae, this being greater in the season of high rainfall (55%). Regarding the morphological and quality characterization, significant differences were obtained in the achenes with respect to their size, weight and moisture content in the high rainfall season, except for C. jussieui, which had the opposite effect. Finally, all the species presented less than 45 germinated achenes (18%), M. vaccinioides and C. jussieui showed a greater number of germinated mature achenes, collected without differences between the periods of high or low rainfall. D. ericoides did not present differences and G. miniphylla only had two germinated semi-mature achenes collected in the high rainfall season.

Publisher's version (útgefin grein), Heart failure (HF) is a leading cause of morbidity and mortality worldwide. A small proportion of HF cases are attributable to monogenic cardiomyopathies and existing genome-wide association studies (GWAS) have yielded only limited insights, leaving the observed heritability of HF largely unexplained. We report results from a GWAS meta-analysis of HF comprising 47,309 cases and 930,014 controls. Twelve independent variants at 11 genomic loci are associated with HF, all of which demonstrate one or more associations with coronary artery disease (CAD), atrial fibrillation, or reduced left ventricular function, suggesting shared genetic aetiology. Functional analysis of non-CAD-associated loci implicate genes involved in cardiac development (MYOZ1, SYNPO2L), protein homoeostasis (BAG3), and cellular senescence (CDKN1A). Mendelian randomisation analysis supports causal roles for several HF risk factors, and demonstrates CAD-independent effects for atrial fibrillation, body mass index, and hypertension. These findings extend our knowledge of the pathways underlying HF and may inform new therapeutic strategies., We acknowledge the contribution from the EchoGen Consortium.

O objetivo do presente trabalho é conhecer as possíveis definições da natureza jurídica do crédito de carbono e confrontá-las com as operações realizadas pelo Projeto de Mecanismo de Desenvolvimento Limpo do Aterro Sanitário Bandeirantes, localizado na cidade de São Paulo. Os procedimentos metodológicos utilizados foram a descrição do procedimento de certificação dos créditos de carbono e da maneira como são comercializados, e posteriormente, foi realizada uma análise comparativa entre as categorias de natureza jurídica de créditos de carbono difundidas pela literatura, commodity ambiental, ativo financeiro, serviço, valor mobiliário e bem intangível puro, com a comercialização das Reduções Certificadas de Emissão do Projeto de Mecanismo de Desenvolvimento Limpo do Aterro Sanitário Bandeirantes. Os resultados apresentados demonstram que os certificados de créditos de carbonos do Mecanismo de Desenvolvimento Limpo do Aterro Sanitário Bandeirantes não possuem materialidade, não são físicos, geraram lucros para seus detentores que superaram oitenta milhões de reais, todavia não houveram vínculos entre vendedores e adquirentes, sendo, portanto, a melhor definição da natureza jurídica dos créditos de carbono a de que são bens intangíveis puros Abstract: não possui

Leukocytes are accumulated, in the inflammatory process, because to action of the wide array of stimuli. This event envolved several and coodenated steps whose inhibited by glucocoticoids, such as dexamethasone. Dexamethasone affects human neutrophils in different ways. It shows negative effects (on synthesis and secretion of pro-inflammatory mediators) and positive effects (for example, on annexin I). Among the inducers of leukocyte migration, MNCF, a galactose-binding lectin, has been described as an agonist and chemoattractant for neutrophils, both in vivo and in vitro. MNCF shows as peculiar activity the migration of neutrophils resistant to dexamethasone actions which awakes great interest in undertanding the mechanism of action on polymorphonuclears by this lectin. Our first step was study human MNCF-stimulated neutrophils pre-incubated with dexamethasone. In these conditions, MNCF, in the absence of F-actin polymerization: (a) protects neutrophils from spontaneous apoptosis, (b) induces tyrosine and p38 MAP quinases phosphorylation, (c) induces CD62L shedding, (d) degranulates secretory vesicles and secundary granules, but not azurophilic granules, in the dependent manner of tyrosine and MAP quinases and Src family, (e) translocates the transcription factor NF-kB and, (f) induces transcription and secretion of pro-inflammatory cytokines and chemokines. In parallel, human neutrophils pre-incubated with dexamethasone and stimulated with MNCF did not show CD62L shedding and F-actin polarization, but the in vitro migration was maintained. Besides, we already observe translocation of NF-kB from cytoplasm to nucleous which it activates the genic transcription and secretion of inflammatory mediators, such as CXCL8. The results, showed here, strengthens previous results, demonstranting that MNCF as a agonist to neutrophils, beyond increase the half life them. Although, dexamethasone modifies some effects of MNCF on neutrophis, this glucocorticoid does not inhibit the cellular response to the studied lectin. Thus, the maintenance of inflammatory mediators, dependents to NF-kB, during the inflammatory process, could explain, even parcialy, the break in the resitance to glucocorticoids actions by MNCF in the neutrophil migration., O acúmulo focal de leucócitos, próprio da inflamação, é desencadeado por uma ampla gama de mediadores, de origens variadas. A migração das células ocorre em múltiplas etapas coordenadas e pode ser inibido por glicocorticóide, que exerce efeitos reguladores negativos -sobre a síntese/ou liberação de moléculas pró-inflamatórias e de adesão- e positivos -sobre a expressão de anexina-1, proteína de ação anti-inflamatória. Temos estudado o efeito indutor de migração de neutrófilos exercido por MNCF (macrophage derived neutrophil chemotactic factor), que é uma lectina ligante de galactosídeos, dotada da propriedade de recrutar neutrófilos mesmo em condição anti-inflamatória, gerada pelo tratamento com dexametasona. Essa atividade peculiar pode ter repercussões relevantes no desenho de estratégias terapêuticas para frear a inflamação quando ela causa lesão tissular. Isso justifica o especial interesse na compreensão dos mecanismos de ação de MNCF sobre neutrófilos humanos. Nesse contexto, demonstramos anteriormente que a interação de MNCF com componentes da matriz extracelular pode contribuir para que a ação desse agente supere o efeito antinflamatório da dexametasona (Toledo et al 2007). Neste trabalho, nosso objetivo é identificar as respostas de ativação dos neutrófilos determinadas por MNCF, de maneira a identificar diferenças entre essas respostas e as desencadeadas por atraentes cujas ações sejam sensíveis ao efeito anti-inflamatório da dexametasona. Ensaios in vitro demonstraram que MNCF, a partir de ligação à superfície celular, induz a migração de neutrófilos humanos, tanto normais como pré-incubados com dexametasona. Ao atuar sobre neutrófilos normais, MNCF induziu respostas qualitativamente muito similares às induzidas por outro atraente, quais sejam: (a) fosforilação de tirosino-quinases e de p38 MAP; (b) shedding de L-selectina; (c) desgranulação de grânulos secundários e vesículas secretórias, mas não de grânulos azurofílicos; (d) resistência à apoptose espontânea; (e) translocação nuclear do fator de transcrição NF-kB; (f) transcrição gênica e secreção de citocinas e quimiocinas próinflamatórias; (g) polarização celular. Os neutrófilos estimulados com MNCF - em comparação aos estimulados com outro atraente (CXCL-8) - polarizaram mais tardiamente e apresentaram níveis superiores de transcrição de genes de mediadores inflamatórios. Quando neutrófilos pré-tratados com dexametasona foram estimulados, os níveis de transcrição gênica de mediadores inflamatórios foram mantidos frente a MNCF e inibidos frente a CXCL8. Dentre os mediadores que tiveram o gene transcrito em níveis altos inclui-se a própria CXCL8, cuja expressão protéica foi também avaliada. Neutrófilos -pré-tratados ou não com dexametasona- estimulados com MNCF secretaram altos níveis de CXCL-8 no sobrenadante. Já, frente a outros estímulos, neutrófilos pré-tratados com dexametasona tiveram a secreção de CXCL8 fortemente inibida. Nossos resultados indicam que os mecanismos envolvidos no fato da inflamação aguda desencadeada por MNCF ser resistente ao efeito de glicocorticóide incluam a capacidade dessa lectina de induzir altos níveis de produção de mediadores inflamatórios, manifesta mesmo em neutrófilos pré-tratados com dexametasona. Nosso estudo está em consonância com os avanços feitos nos últimos dez anos no campo de investigações sobre neutrófilos, que atribuem a essas células funções mais complexas do que a ingestão e eliminação de microorganismos, com destaque para a sua capacidade de transcrever genes e expressar produtos que estão intimamente ligados às respostas inflamatória e imunitária.

Tesis (Ingeniero de Ejecución en Gestión Informática) En la actualidad uno de los recursos más valiosos es el tiempo, es por esto que en los sistemas de información es vital contar con datos válidos y consistentes para una entrega óptima de información, de lo contrario ésta inconsistencia puede repercutir en procesos posteriores, generando pérdida de tiempo, dinero y recursos en general. Por lo descrito anteriormente se hace muy necesario contar con herramientas que permitan controlar la veracidad de los datos obtenidos como también el desempeño del personal que la genera. Este proyecto se enfoca en el desarrollo de una herramienta que controle en la etapa de recepción de encargo, como también validar los datos proporcionados por los tasadores y entregar para un determinado proceso el mejoramiento de los informes a través de ciertos parámetros fijos antes de la directa supervisión de estos, junto con la medición y control del desempeño de quienes los generan, las medidas propuestas implicaran un mejoramiento en la calidad y tiempo en el proceso de supervisión ya que en la actualidad no se logra cumplir el mínimo de revisión de informes y se corre el riesgo de enviar a los clientes información inconsistente.

Diabéticos ,Cuidado y Tratamiento - Abstract
Tesis (Licenciado en Enfermería) La diabetes mellitus es conocida desde antes de la era cristiana. Antes del descubrimiento de la insulina, el diagnóstico de diabetes era una sentencia de muerte a corto plazo. Esto se debía a que la mayoría de los pacientes tenía lo que hoy llamamos diabetes mellitus tipo 1 En ese entonces la expectativa de vida de la población general era tan corta, que muy pocas personas llegaban a tener edad como para desarrollar una diabetes tipo 2. En el año 1921 se descubre la insulina, lo cual trajo optimismo, ya que tuvo mucho éxito evitando la muerte de quienes padecían diabetes. El descubrimiento de la insulina permitió que quienes padecían diabetes vivieran durante décadas, aumentando la expectativa de vida. Como consecuencia de lo anterior, la diabetes mellitus constituye actualmente una epidemia global, ya que afecta a más del 2% de la población mundial, sumando en Chile 400 mil personas. En segundo lugar, la gran población de diabéticos (10% tipo 1 y 90% tipo 2) sufre con frecuencia de las complicaciones crónicas de la hiperglicemia (retinopatía, nefropatía y neuropatía), que se han constituido en graves problemas de salud pública . La importancia de este problema deriva de su frecuencia y de sus complicaciones crónicas, micro y macrovasculares, constituyendo una de las principales causas de invalidez y mortalidad prematura en la mayoría de los países desarrollados, además afecta a la calidad de vida de las personas con dicha patología . En el mundo Occidental la prevalencia de Diabetes Mellitus se estima que oscila entre el 2 y el 6% de la población. Se estima que un 50% de los casos permanecen sin diagnosticar: por cada persona con diabetes conocida existe una con diabetes desconocida. Aproximadamente el 60-70% de los pacientes con diabetes tienen algún grado de neuropatía

Background: Eugenia spp. are used in popular medicine in the treatment of pain, diabetes, intestinal disorders and cough. The aim of the work is to evaluate, ex vivo and in vivo, the anti-inflammatory activity of the hydroethanolic extracts of the leaves of Eugenia aurata (EA) and Eugenia punicifolia HBK (EP) upon neutrophils. Methods: Ex vivo, isolated human neutrophils were sensitized by Eugenia extracts (0.1-1000 µg/mL) and stimulated by PMA. In these conditions, different neutrophil activities related to inflammatory process were measured: adhesion, degranulation and NET release. Neutrophil viability and tumor line cells were monitored. In vivo, neutrophil influx was evaluated by peritonitis model performed in mice pretreated with different concentrations of Eugenia extracts. Phytochemical profile was assessed by mass spectrometry. Results: Ex vivo, EA and EP (1000 µg/mL) reduced cell adhesion and degranulation, respectively. NET release was inhibited by EA and EP. Anti-inflammatory activities occurred in the absence of cytotoxicity. In vivo, both EA as EP inhibited neutrophil migration. The phytochemical profile revealed that EA contains myricitrin, rutin, quinic acid and quercetin derivatives. EP presents gallic acid, quercetin derivatives, syringic acid, ellagic acid, monogalloyl-glucose, glycosyringic acid, mudanoside B, HHDP glucose isomer and digalloylglucose isomer. EA and EP inhibit neutrophil migration by different pathways. Conclusion: Different chemical compositions may explain the anti-inflammatory effects described herein for EA and EP. Both extracts inhibit NET release but only EA reduces cell adhesion whereas EP decreases elastase secretion. This work contributes to the elucidation of cellular mechanisms related to the anti-inflammatory activity for leaves of E aurata and E punicifolia HBK. [ABSTRACT FROM AUTHOR]

Além da elucidação dos mecanismos de ação, os mecanismos subjacentes à oxidação lipídica em sistemas complexos, como as membranas plasmáticas, são importantes para eficiência da TFD. Contudo, ambos os mecanismos permanecem elusivos. Nesta dissertação de mestrado, investigamos através de filmes de Langmuir as interações moleculares que permitem a adsorção do FS eritrosina em monocamadas lipídicas e os resultados da fotooxidação subsequentes. Além disso, a eficiência fotodinâmica e os mecanismos de morte celular induzido pelo FS fotoativado em células derivadas do carcinoma de orofaringe (HEp-2) e mamário (MCF7) foram avaliados com citometria de fluxo e marcação de fluorescência. Os filmes de Langmuir foram inicialmente construídos com os fosfolipídeos 2-dioleoil-sn-glicero-3-fosfocolina (DOPC), 1,2-dioleoil-sn-glicero-3-fosfo-L-serina (DOPS) e a mistura DOPC/DOPS, mimetizando membranas plasmáticas tumorais. Em um segundo momento, as monocamadas foram construídas com o extrato lipídico extraído das células MCF7. Os efeitos fotodinâmicos nas células MCF7 foram mais pronunciados do que nas células HEp-2. Em ambos os casos, a incubação da eritrosina não irradiada, não gera efeitos citotóxicos significativos, desencadeando apoptose no cultivo in vitro a partir de 24 h incubação. Por outro lado, a viabilidade celular é significativamente reduzida sob irradiação, desencadeando o mecanismo de morte celular por necrose. Modelos inspirados na membrana tumoral baseados em monocamadas de Langmuir mistas de DOPC e DOPS revelaram que interações eletrostáticas com a cabeça dos lipídeos são as principais forças de adsorção da eritrosina. Nas monocamadas construídas com extrato lipídico da MCF7, a adsorção da eritrosina é dirigida por interações secundárias que afetam a orientação dos grupos carbonil e a organização das cadeias lipídicas. A irradiação do FS nas monocamadas induz a hidroperoxidação lipídica, que pode ainda sofrer decomposição, resultando na clivagem da cadeia de fosfolipídeos e permeabilização da membrana. De fato, a clivagem lipídica, e os subprodutos gerados, foram detectados por espectroscopia de massa, sustentando o caminho necrótico de morte celular observadas nos ensaios in vitro. In order to develop more efficient and less invasive therapies in the treatment of tumors, photodynamic therapy (PDT) has gained prominence. In addition to elucidate the mechanism of action, the subjacent mechanism of lipid oxidation in complex systems, such as plasma membranes, are important for PDT efficiency. However, both mechanisms remain elusive. In this work, the molecular interactions allowing the adsorption of the PS erythrosine and the subsequent photooxidation reactions were investigated using Langmuir films. Besides, the photodynamic efficiency and cell death mechanism induced by the photoactivated PS in cells derived from oropharyngeal (HEp-2) and mammary (MCF7) carcinomas were evaluated by flow cytometry and fluorescence labeling. Langmuir films were first built with 2-dioleoyl-sn- glycero-3-phosphocholine (DOPC) and 1,2-dioleoyl-sn-glycero-3-phospho-L-serine (DOPS) phospholipids and the DOPC/DOPS mixture, simulating the literature regarding tumor plasma membranes. In a second step, the monolayers were built with the lipid extract from the MCF7 cells. Photodynamic effects in MCF7 cells were more pronounced than in HEp-2 cells. In both cases, the incubation of non-irradiated erythrosine does not generate significant cytotoxic effects, triggering apoptosis on in vitro culture after 24 h of incubation. On the other hand, cell viability is significantly reduced under irradiation, triggering the mechanism of cell death by necrosis. Tumor membrane models based on mixed Langmuir monolayers of DOPC and DOPS revealed that electrostatic interactions with the lipid head is the main driving forces allowing erythrosine adsorption. In monolayers built with MCF7 lipid extract, erythrosine adsorption is driven by secondary interactions that affect the orientation of carbonyl groups and the organization of lipid chains. Irradiation of FS on monolayers induces lipid hydroperoxidation, which can further undergo decomposition, resulting in phospholipid chain cleavage and membrane permeabilization. Indeed, lipid cleavage, and the by-products generated, were detected by mass spectroscopy, supporting the necrotic pathway of cell death observed in in vitro assays. CAPES-PROEX

O Vírus Sincicial Respiratório (RSV) causa bronquiolite e pneumonia, especialmente em recém-nascidos e idosos, o que resulta em milhões de mortes e hospitalizações. Sua glicoproteína de superfície F – proteína de fusão – é responsável pela fusão do envelope viral à membrana celular. Diversos flavonoides demonstram atividade anti-RSV por meio do mecanismo virucida. Assim, os objetivos desse trabalho foram analisar a interação da proteína F modelada neste trabalho (RSVmF) com o flavonoide quercetina, seu derivado pentacetilado (Q1) e um ligante-referência (JNJ- 2408068) por docking e dinâmica molecular (DM). Ademais, elaboramos uma rede neural artificial (ANN) assessorada pelo algoritmo genético para predizer a capacidade anti- RSV de flavonoides. A modelagem da estrutura completa da proteína F, os dockings, a DM, e a ANN foram realizados, respectivamente, no servidor I-TASSER, no Auto- Dock/Vina 1.1.2., no Amber/14, e na plataforma Matlab®. Os experimentos de docking indicaram que os três ligantes preenchem a cavidade central de RSVmF e apresentam energia de interação em torno de -6,5 kcal/mol. Análises de DM revelaram tendência ao escape da cavidade para quercetina, enquanto Q1 e ligante-referência permanecem nela. Cálculos de MM-GBSA mostraram ΔG (kcal/mol) dos complexos RSVmFquercetina= -4,92, RSVmF-Q1= -14,22, e RSVmF-inibidor = -22,78. Logo, a acetilação da quercetina aumentou sua capacidade virucida por favorecer a interação com a cavidade de RSVmF. Quanto à ANN, os resultados obtidos a partir de uma amostra (n=240 dados, referentes a 70 flavonoides), indicaram três possíveis modelos de predição, dentre os quais ANN-g2 obteve uma acurácia de 90% para predição de flavonoides “ativos” e 93,3% para “inativos”. O principal ganho referente ao nosso estudo é o respaldo à relevância de um planejamento racional de procedimentos experimentais, pela exclusão preliminar de flavonoides inativos e a pré-seleção de ativos. Breathing is a basic requirement for survival of human life and the respiratory tract is therefore a frequent target for pathogens. Respiratory syncytial virus (RSV) causes bronchiolitis and pneumonia, mainly in newborns and the elderly, which results in millions of deaths and hospitalizations. Its surface glycoprotein F – fusion protein – is responsible for the fusion of the viral envelope to cell membrane. Several flavonoids were shown to exert anti-RSV activity by virucidal mechanism. Thus, the aims of this study were to analyze the interaction of the F protein modeled herein (RSVmF) in complex with flavonoid quercetin, with its pentacetylated derivative (Q1) and with a reference-ligand (JNJ-2408068), by docking and molecular dynamics (MD). Moreover, we developed an artificial neural network (ANN), assisted by the genetic algorithm to predict the anti-RSV activity of flavonoids. The modeling of the complete protein F structure, dockings, DM, and ANN were performed, respectively, on I-TASSER server, Auto-Dock/Vina 1.1.2., Amber/14, and Matlab® platform. Docking experiments indicated that the three ligands fill RSVmF central cavity and present an interaction energy of about -6.5 kcal/mol. MD analyses revealed an escaping trend from the cavity to quercetin, whereas Q1 and the reference-ligand remain in it. MM-GBSA calculations showed ΔG (kcal/mol) for the complexes RSVmF-quercetin= -4.92, RSVmF-Q1= -14.22, and RSVmF-inhibitor = - 22.78. Therefore, the acetylation of quercetin increased its virucidal activity by favoring the interaction with RSVmF cavity. ANN results were obtained from a sample (n = 240 data, regarding 70 flavonoids) and indicated three possible predictive models, among which ANN-g2 revealed an accuracy of 90% for prediction of “active” flavonoids and 93.3% for "inactive" ones. The major achievement of our study is that it has demonstrated the relevance of rational planning of experimental procedures, by the preliminary exclusion of inactive flavonoids and the pre-selection of active ones.

Dentre os agentes etiológicos destas infecções, o Vírus Sincicial Respiratório Humano (hRSV) contribui para vários casos de bronquiolite, pneumonia e infecções pulmonares obstrutivas crônicas em pessoas de todas as idades, principalmente em crianças e idosos. Atualmente não existe vacinas ou medicamentos eficazes com atividade anti-hRSV. A semi-síntese a partir de moléculas naturais tem sido uma estratégia promissora na melhora da atividade biológica de compostos naturais. Assim, o objetivo deste trabalho foi avaliar a atividade antiviral in vitro da Quercetina Penta-acetilada (QPA) em células permissivas à infecção/replicação por hRSV (HEp-2). Os ensaios antivirais foram realizados com diferentes MOIs (0.1, 0.5 e 1.0) e analisados por adição do sal de MTT e posteriormente confirmados por ensaio de placa de lise. O composto QPA apresentou atividade anti-hRSV nos protocolos virucida e de pós-tratamento. O efeito virucida de QPA foi confirmado pelos ensaios de adsorção e tempo de adição. QPA inibiu a adsorção e os ensaios de tempo de adição confirmaram que a ação de QPA se dá principalmente nas primeiras fases do ciclo viral. Por meio do ensaio de placa de lise foi possível demonstrar e confirmar que a redução do número de focos virais nos protocolos virucida e pós-tratamento foi de 50%. Nossos dados indicam que o composto QPA apresenta um promissor papel anti-hRSV, por interagir com a partícula viral e inibir sua adesão à célula. Lower respiratory tract infections are the main cause of infections in children, reaching approximately 12 million severe cases and 3 million very serious cases around the world. The human pneumovirus Respiratory Syncytial Virus (RSV) is the major pathogen found in these cases and contributes to several cases of bronchiolitis, pneumonia and chronic obstructive pulmonary infections in people of all ages, especially in infants and the elderly. There are currently no vaccines and the therapeutic strategies in use present little efficacy or restricted use. Flavonoids are the focus of several studies that seek for effective and cost-effective antiviral drugs. Quercetin, a flavonoid commonly found in the human diet, has an inhibitory activity against several types of virus, including RSV. Chemical modification of molecules has been proven as a promising strategy to improve the biological activity of natural compounds. The aim of this work was to evaluate the antiviral activity of Quercetin Pentaacetate (QPA) against RSV in culture of HEP-2 cells in different protocols. The antiviral assays were performed with different MOIs (0.1, 0.5 and 1.0), evaluated by of MTT protocol and confirmed by plaque assay. QPA showed virucidal activity against RSV Such effect was confirmed by adsorption and addition time assays. QPA presented inhibitory activity in the adsorption and addition time assays, what confirmed that its activity occurs mainly in the early phases of the viral cycle. The plaque assay confirmed that the reduction in the number of viral foci in virucidal protocols was 50%. Our data indicate that QPA possess a promising anti-RSV activity, which is suggested to be related with the interference of RSV-F fusion activity. FAPESP-14/12298-7

No sítio de infecção, neutrófilos secretam NETs (Neutrophil Extracellular Traps) ,fibras de DNA decoradas com proteínas nucleares, granulares e citoplasmáticas. As NETs contribuem para a captura e inativação de diversos microorganismos. Um corpo crescente de evidências tem apresentado que o acúmulo das NETs resulta em efeitos citotóxicos diretos sobre células endoteliais e epiteliais. O hRSV (human Respiratory Syncytial Virus), é a causa mais comum de doença grave do trato respiratório inferior em crianças pequenas em todo o mundo, gerando um alto número de hospitalizações e um alto custo para o sistema de saúde. Neutrófilos estimulados pela proteína F do hRSV geram NETs capazes de capturar partículas virais e assim reduzir a disseminação viral. A massiva produção de NETs causa obstrução das vias aéreas e contribui para o agravamento da doença. O presente estudo teve por objetivo avaliar os efeitos benéficos e/ou deletérios das NETs no curso da infecção pelo hRSV. Para tanto, células Hep-2 foram infectadas in vitro com diferentes inóculos de hRSV, antes ou depois de terem sido incubadas com as NETs (0.5-16 µg/mL). Células apenas infectadas apresentaram redução na taxa metabólica, intensa coloração com azul de trypan, formação de numeros e volumosos sincícios. Comparativamente, o contato das células com as NETs, antes da infeçcão viral (MOI 0.1), resultou em melhora da taxa metabólica e da viabilidade celular, acompanhadas de redução no número e dimensão dos sincícios formados. O aumento do inóculo viral (MOIs 0.5 e 1) reduziu tais efeitos benéficos. Células já infectadas e, que foram pós-tratadas com as NETs, apresentaram sincícios mais volumosos, que numericamente estavam reduzidos. O aumento na concentração das NETs (≥ 8µg/mL) agravou a mortalidade celular, o que refletiu numa redução do número e da dimensão dos sincícios formados. Análises in silico, foram favoráveis à geração de complexos proteína F/MPO e proteína F/Catapsina-G, envolvendo sítios de neutralização viral. Em resumo, nas fases precoces da infecção, onde a concentração das NETs e a carga viral estão reduzidas, há um predominante efeito benéfico das NETs, que contribui na captura do virion e na proteção de células não infectadas. A intensa geração das NETs em fases mais tardias da infecção, causa agravamento da morte celular. O detalhamento dos mecanismos envolvidos no equilibrado papel das NETs, na imunopatologia das doenças respiratórias, fornece subsídios para o desenvolvimento de estratégias terapêuticas que modulem a geração e a função das NETs no tecido pulmonar. Neutrophils are recruited into the lung tissue of patients suffering from various respiratory diseases. At the site of infection, neutrophils secrete NETs (Neutrophil Extracellular Traps), DNA fibers decorated with nuclear, granular and cytoplasmic proteins. NETs contribute to the capture and inactivation of various microorganisms. A growing body of evidence has shown that the accumulation of NETs results in direct cytotoxic effects on endothelial and epithelial cells. Human Respiratory Syncytial Virus (hRSV) is the most common cause of severe lower respiratory tract disease in young children worldwide, leading to a high number of hospitalizations and a high cost to the health system. Neutrophils stimulated by hRSV F protein generate NETs capable of capturing viral particles and thus reduce viral spread. The massive production of NETs causes obstruction of the airways and contributes to the worsening of the disease. The present study aimed to evaluate the beneficial and/or deleterious effects of NETs in the course of hRSV infection. To this end, Hep-2 cells were in vitro infected with different hRSV load, either before or after incubation with the NETs (0.5-16 μg/mL). Infected cells had a reduction in the metabolic rate, intense staining with trypan blue, number formation and large syncytia. Cell contact with NETs prior to viral infection (MOI 0.1) resulted in improved metabolic rate and cell viability, accompanied by a reduction in the number and size of the syncytia. The increase of the viral inoculum (MOIs 0.5 and 1) reduced such beneficial effects. Already infected cells, which were post-treated with the NETs, presented larger syncytia, which were numerically reduced. The increase in NET concentration (≥ 8μg/mL) worsened cellular mortality, which reflected a reduction in the number and size of the syncytia. In silico analyzes, they favored the generation of F protein/MPO and F protein/Catapsin-G complexes, involving viral neutralization sites. In summary, in the early infection stages, where NETs concentration and viral load are low, there is a predominant beneficial effect of NETs, which contributes to virion capture and protection of uninfected cells. The intense generation of NETs in later infection stages causes worsening of cell death. Detailing the mechanisms involved in the balanced role of NETs in the immunopathology of respiratory diseases provides support for the development of therapeutic strategies that modulate the generation and function of NETs in lung tissue.

Durante o processo inflamatório, neutrófilos são as primeiras células a serem recrutadas por estarem diretamente relacionadas à ativação e resolução destes processos. Assim, frequentemente estas células são alvos para novos compostos anti-inflamatórios. A descrição da atividade anti-inflamatória de rutina e quercetina se estende para vários ativadores das vias clássicas dos neutrófilos. O estudo quanto aos compostos forbol ésteres, como PMA (phorbol myristate acetate), que ativam de maneira específica a sinalização da proteína quinase C, ainda são escassos.O objetivo deste trabalho foi analisar a atividade anti-inflamatória de rutina e quercetina sobre neutrófilos ativados por PMA. Para tanto, foram analisadas etapas importantes do processo inflamatório mediadas pelos neutrófilos: adesão, desgranulação, e liberação das NETs (Neutrophil Extracelular Traps). Nossos resultados demonstraram que, ativação de neutrófilos por PMA: (i) rutina e quercetina não inibem a adesão dos neutrófilos, (ii) quercetina inibe a desgranulção, (iii) ambos inibem a atividade da mieloperoxidase (MPO), assim como (iv) inibem a liberação das NETs na ausência de morte celular. Análises de docking molecular sugerem que tais eventos podem estar relacionados à geração de complexos quercetina/MPO e rutina/elastase. Rutin and Quercetin are flavonoids found in several foods, including those indicated as a supplement in the inflammatory treatment diseases. During the inflammatory process, neutrophils are the first cells to be recruited. They are directly related to the activation and resolution of these processes. Thus, these cells often target new anti-inflammatory compounds. The description of the anti-inflammatory activity of rutin and quercetin extends to several activators of classical neutrophil pathways. Studies involving forbol esters compounds, as PMA ((phorbol myristate acetate), which activate in a specific manner the protein kinase signalling, it is still poor. The aim of this study was to analyze the anti-inflammatory activity of rutin and quercetin on PMA-activated neutrophils. For this, important steps of the inflammatory process mediated by neutrophils were analyzed: adhesion, degranulation, and release of NETs (Neutrophil Extracelular Traps). Our results demonstrated that neutrophil activation by PMA: (i) rutin and quercetin did not inhibit neutrophil adhesion, (ii) quercetin inhibited degranulation, (iii) both inhibited myeloperoxidase activity (MPO), as well as (iv) both Inhibit the release of NETs in the absence of cell death. Molecular docking analyzes suggest that such events may be related to the generation of quercetin/MPO and rutin/elastase complexes.

A despeito de décadas de inúmeras pesquisas em busca de compostos anti-hRSV, atualmente não existem vacinas ou medicamentos eficazes contra esta infecção viral. Dentre os leucócitos presentes nas vias aéreas de indivíduos acometidos por hRSV, os neutrófilos são predominantes e se mostram em estado de ativação, incluindo a indução da liberação das NETs. As NETs, compostas por DNA e proteínas granulares/nucleares tem sido descritas como eficientes na captura e eliminação de diversos microrganismos. Em relação ao hRSV, o vírus induz a liberação das NETs no tecido pulmonar de indivíduos infectados, mas as consequências desse evento ainda não foram elucidadas. O objetivo deste trabalho foi investigar se as NETs possuem algum efeito anti-hRSV. Para tanto, foram realizados ensaios in vitro e in silico. NETs geradas a partir do estímulo com PMA e avaliadas por eletroforese apresentaram longos fragmentos de DNA e proteínas de peso molecular próximos daqueles determinados para elastase, catepsina G, mieloperoxidase e histonas. As NETs apresentaram índices de citotoxicidade celular abaixo de 50%, com uma CC50 >67μg/mL. Ensaio virucida realizado com diferentes MOIs (0.1, 0.5 e 1.0), mostraram eficiência das NETs (CE50 ≅ 1 e IS ≅ 66). As interações obtidas in silico demonstram forte interação entre as proteínas elastase e histonas com a proteína F-hRSV, pré e pós-fusão, em regiões importantes para a infecção/replicação do vírus. Os dados obtidos indicam que as NETs tem um promissor papel antiviral e este efeito pode estar relacionado à sua ação direta na captura de partículas virais e/ou na interferência da atividade de fusão da proteína F. Em conclusão, nossos resultados associados a dados prévios da literatura, apontam que o contato do hRSV com os neutrófilos induz a liberação das NETs e que estas agem na neutralização do vírus. Annualy the Human Respiratory Syncytial Virus (hRSV) acts as one of the main etiological agents of more than 15 million infections in the lower respiratory tract of children and elderly. Despite decades of extensive research in search of anti-hRSV compounds, there are currently no vaccines or effective drugs against this viral infection. Among the present leukocytes in the airways of individuals affected by hRSV, the neutrophils are predominant and are shown in activation state, including the induction of the release of NETs. NETs, composed by DNA and glanular/nuclear proteins have been described as efficient in capturing and eliminating several microorganisms. Regarding hRSV, the virus induces the release of NETs in the lung tissue of infected individuals, but the consequences of this event have not yet been elucidated. The goal of this study was to investigate whether the NETs have some anti-hRSV effect. For that purpose, assays were performed in vitro and in silico. NETs generated from the stimulation with PMA and evaluated by electrophoresis showed long DNA fragments and proteins of molecular weight close to those determined for elastase, cathepsin G, myeloperoxidase, and histones. The NETs presented cellular cytotoxicity indices below 50%, with CC50 >67μg/mL. Virucide assay performed with different MOIs (0.1, 0.5 and 1.0), showed efficiency of the NETs (CE50 ≅ 1 and IS ≅ 66). The interactions obtained in silico demonstrate strong interaction between elastase and histone proteins with the F-hRSV protein, pre and postfusion, in important regions for the infection/replication of the virus. The data obtained up to date indicate that the NETs have a promising antiviral role and this effect may be related to its direct action in the capture of viral particles and/or interference of the fusion activity of F protein. In conclusion, our results associated with previous literature data, indicate that the contact of the hRSV with neutrophils induces the release of NETs and that these act in the neutralization of the virus.

Dentre os agentes etiológicos destas infecções, o vírus sincicial respiratório humano (hRSV) é a principal causa de internações infantis em países desenvolvidos, agravando os casos de bronquiolite, pneumonia e infecções pulmonares obstrutivas crônicas em pessoas de todas as idades, principalmente crianças e idosos. Estudos preliminares demonstraram que a Quercetina possui ação virucida sobre hRSV, além de inibir sua replicação. Entretanto, não se tem conhecimento do quão promissora é a atividade antiviral de Quercetina sobre o vírus hRSV ou mesmo se esta atividade poderia ser melhorada através de mudanças químicas em sua estrutura molecular. Assim, o objetivo deste trabalho foi estabelecer o índice de seletividade (IS) para Quercetina e seus derivados acetilados durante a infeção por hRSV através de ensaios in vitro. A análise de viabilidade celular através da adição do sal de MTT determinou os valores de CC50 para Quercetina na presença/ausência do vermelho de fenol (85 e 11,4 µM, respectivamente). Dentre as condições testadas, Quercetina apresentou atividade virucida (16-30% de proteção celular) sem apresentar efeitos no pré ou pós-tratamentos. Os valores de CC50 dos compostos derivados Q1 e Q2 foram 37,1 µM e 53,15 µM, respectivamente. O composto Q1 apresentou atividade anti-hRSV nos protocolos virucida e pós-tratamento (60-90%; 4-8 µM). O composto Q2 não apresentou atividade anti-hRSV relevante em nenhuma das condições testadas. A proteção celular apresentada pela Quercetina não possibilitou o cálculo de IS (CC50/CE50) o que nos sugere que este composto não seja um promissor agente anti-hRSV. Os índices de Seletividade calculados para o composto Q1 nos protocolos virucida e pós-tratamento foi de 9,27. O conjunto de resultados obtidos neste trabalho apresenta menor citotoxicidade e melhor performance anti-hRSV do composto Q1 em relação à Quercetina comercial. Estes dados nos estimulam a dar continuidade aos estudos do composto Q1 com o intuito de melhorarmos sua atividade antiviral e assim propormos um novo composto que seja efetivos na prevenção e/ou tratamento das infecções por hRSV. Worldwide, is estimated that there are about 12 million serious cases and 3 million severe cases of lower respiratory tract infection in children every year. Among the etiological agents of these infections, respiratory syncytial virus (hRSV) is the leading cause of children's hospitalizations in developed countries, aggravating cases of bronchiolitis, pneumonia and chronic obstructive pulmonary infections in people of all ages, especially children and the elderly. Preliminary studies demonstrated that Quercetin has virucidal action on hRSV, and inhibits replication. However, we do not know how promising is the antiviral activity of Quercetin on the hRSV. The objectives of this work is to understand the action of Quercetin and some of its derivatives acetylated on the steps of the replicative cycle of hRSV, determining the selectivity index for each compound. The development of this project will assist in the search for effective compounds in the prevention and/or treatment of hRSV infections. In the cytotoxicity assays, Quercetin showed CC50 values variable depending on the presence/absence of phenol red (11.4 and 85 μM respectively). Among the concentrations tested Quercetin only showed a slight virucidal activity (16-30% concentration 5-10 μM). The CC50 values were derived compounds 37.1 μM for Q1 and Q2 to 53.15 μM. Compound Q1 showed anti-hRSV activity in virucidal and post-treatment protocol (60-90% at 4-8 μM). The Q2 compound showed no anti-hRSV relevant activity. The presence or absence of phenol red had great influence in determining the CC50 values of Quercetin (11.4 μM and 85 μM with phenol red). In addition, Quercetin showed little (virucidal protocol without phenol) or no anti-hRSV activity. Thus it has not been possible to establish the EC50 of Quercetin and determine its selectivity index (SI). The Q1 compound showed a greater CC50 value (37.1 μM) and relevant anti-hRSV activity in post-treatment and virucidal protocols (SI 9.27). Among the compounds tested, Q2 showed the highest value of CC50 (53.15 μM without phenol) however, had little or no anti-hRSV activity, making it impossible to determine their SI.

Quando centrifugado ocorre a separação das proteínas relacionadas às reações alérgicas, porém permanecem as proteínas relacionadas à atividade angiogênica que este material tem apresentado. Suas aplicações biológicas têm crescido devido à atividade angiogênica e por apresentar baixo custo e fácil processamento. Dentre suas aplicações pode-se citar a liberação de compostos ativos (fármacos, extratos, nanopartículas, entre outros), uso como emplasto (acelerando a cicatrização de úlceras crônicas), prótese vascular, etc. Também tem sido utilizada como barreira mecânica na regeneração óssea guiada (GBR), mostrando-se eficiente e acelerando a cicatrização óssea. Desta forma, este trabalho se baseou em testar a citotoxicidade das membranas de látex natural; produzir membranas com diferentes porosidades; avaliar a adesão de pré-osteoblastos; testar a mineralização celular na membrana com maior porosidade. A citotoxicidade foi avaliada segundo a norma técnica ISO 10993-5 (pelo teste de extração do material); as membranas foram elaboradas segundo a técnica de separação de fases induzida termicamente (TIPS) a fim de proporcionar porosidade nas membranas e caracterizadas por microscópio eletrônico de varredura com energia dispersiva de raio-X (MEV-EDS), espectroscopia no infravermelho (FTIR-ATR) e resistência a tração; a adesão e morfologia celular da célula MC3T3-E1 subclone 14 foi avaliada pelo MEV e microscopia óptica; a mineralização foi avaliada por MTT, MEV-EDS, FTIR-ATR, vermelho de alizarina S, von Kossa e fosfatase alcalina. A membrana foi tóxica para o extrato na concentração de 100%, porém nas concentrações abaixo de 80% já não apresentava toxicidade. Todas as membranas continham irregularidades em sua... The natural rubber latex (NRL) extracted from the rubber tree Hevea brasiliensis is a colloidal system composed of cis-14-polyisoprene polymer. The centrifugation separates the proteins related to allergic reactions, preserving the proteins related to angiogenic activity presented by this material. Their biological applications have grown due to the angiogenic activity and due to its low cost and easy handling. Among its applications, one can mention the release of active compounds (drugs, extracts, nanoparticles, etc.), use as a wound dressing (accelerating the healing of chronic ulcers), vascular prosthesis, etc. It has also been used as a mechanical barrier in guided bone regeneration (GBR), being efficient and accelerating bone healing. Thus, this work aimed a cytotoxicity test of natural rubber latex membrane; producing membranes with different porosities; and assess the adherence of pre-osteoblasts; a mineralization test in the membrane with higher porosity. Cytotoxicity was tested according to the standard ISO 10993-5; the membranes were produced by thermally induced phase separation (TIPS) to provide porosity in the membranes and characterized by scanning electron microscopy with energy dispersive X-ray (SEM-EDS), infrared spectroscopy (FTIR-ATR ) and tensile strength; cell adhesion and morphology of MC3T3-E1 cell subclone 14 was evaluated by SEM-EDS and optical microscopy; mineralization was assessed by MTT, SEM-EDS, FTIR-ATR, alizarin red S, von Kossa staining, and alkaline phosphatase. The membrane was toxic to extract at concentration of100%, but at concentration lower than 80% no longer showed toxicity. All membranes presented irregularities on its surface, with porosity only in those produced at -10°C to -20°C, the latter with higher pores and was tested for mineralization. FTIR-ATR showed no change in the functional groups due to processing and the tensile test showed a typical...

Em meio a seus membros, as espécies de Eugenia spp., ricas em compostos fenólicos, parecem apresentar efeitos pró e anti-inflamatórios quando testados in vivo e in vitro. Dentre as células atuantes de forma pioneira na inflamação, estão os neutrófilos. Eles são um alvo de estudo no controle de processos inflamatórios agudos e crônicos, por meio da elucidação de como substâncias agem, por exemplo, nas diferentes etapas de seu recrutamento. Assim, o objetivo principal deste trabalho foi avaliar o potencial efeito anti-inflamatório do extrato hidroetanólico de folhas de Eugenia aurata - EA e Eugenia punicifolia - EP, sobre atividades neutrofílicas. Foram avaliados os processos de adesão e desgranulação celular e a geração das armadilhas extracelulares neutrofílicas (NETs- Neutrophil Extracellular Traps) em neutrófilos humanos. Os resultados mostram que o EA inibe o processo de adesão, enquanto que o EP, a desgranulação, e, ademais, ambos inibem a liberação de DNA (NET), na ausência de efeito citotóxico. Tais resultados corroboram o uso desses extratos na medicina popular. Além disso, sugerem seu potencial no desenvolvimento de medicamentos fitoterápicos com propriedades anti-inflamatórias Myrtaceae family has been studied for its potential in regulating menstruation, pain and intestinal disorders, infertility, as well as antifungal, purgative and anticancer agent, and in addition to treat colds, cough and other respiratory ailments. Amid its members, Eugenia spp species appear to have pro and anti-inflammatory effect once examined in vivo and in vitro. Among the first cells which act on inflammation site, there are the neutrophils. They are a matter of study in the controlling of acute and chronic inflammatory processes, through elucidation of how substances act, for example, in different steps of their recruitment. Therefore, the main aim of this study was to evaluate the potential anti-inflammatory effect of hydroethanolic extract of Eugenia aurata leaves - EA and Eugenia punicifolia - EP, on neutrophil activities. We evaluated the adhesion process and cell degranulation, as well NETs (Neutrophil Extracellular Traps NETs) generation in human neutrophils. The results show that EA inhibits adhesion, while EP degranulation, and further, both inhibit the release of DNA (NET), in the absence of cytotoxic effect. These results give support to the use of these extracts in the popular medicine. Furthermore, they demonstrate a potential of both extracts for the development of phytomedicines with anti-inflammatory properties
