ABSTRACT: In Brazil, urea is the most used nitrogen (N) fertilizer to improve forage production. However, their excessive use can cause environmental impacts through N losses, such as ammonia (NH3) volatilization. Therefore, the current study adjusted and estimated the NH3 volatilization from urea applied on tropical pastures in three rainfall conditions using mathematical models. Data were collected from Marandu grass (Brachiaria brizantha) fertilized with 50 kg N ha-1 during wet, intermediate, and dry conditions. Ammonia volatilization was measured in five semi-open chambers for 21 days. The linear, quadratic, exponential, Gompertz, Groot, and Richards models were tested for fitting and estimating the NH3 volatilization. The Gompertz, Groot, and Richards models generated predictions similar to the observed data, with a high determination coefficient, indicating a better fit of these equations to data, with precision and accuracy. However, the Groot model was selected due to the lowest root mean square error of prediction (0.29 % total N lost as NH3). The greatest N loss as NH3 volatilization occurred in the wet, followed by intermediate and dry conditions (20.2, 17.0, and 11.3 % total N lost as NH3, respectively). Therefore, nitrogen losses as NH3 volatilization after application of 50 kg N ha-1, as urea source, are altered according to the weather conditions, reaching 20% of N added in the wet rainfall period. The Groot model is recommended for fitting and estimating the NH3 volatilization from urea applied on Marandu grass pastures in the wet and dry rainfall conditions.

RESUMO: No Brasil, a ureia é o fertilizante nitrogenado mais utilizado para melhorar a produção de forragem. No entanto, seu uso excessivo pode causar impactos ambientais por meio de perdas de nitrogênio (N), como a volatilização da amônia (NH3). Portanto, o objetivo do presente estudo foi ajustar a volatilização de NH3 da ureia aplicada em pastos tropicais em três condições de chuva utilizando modelos matemáticos. Dados foram coletados de pastos de capim-marandu (Brachiaria brizantha) adubado com 50 kg N ha-1 em condições úmidas, intermediárias e secas. A volatilização da NH3 foi medida em cinco câmaras semiabertas durante 21 dias. Os modelos, linear, quadrático, exponencial, Gompertz, Groot e Richards foram testados para ajuste e estimativa da volatilização do NH3. Os modelos de Gompertz, Groot e Richards geraram predições semelhantes aos dados observados, com alto coeficiente de determinação, indicando um melhor ajuste dessas equações aos dados, com acurácia e precisão. No entanto, o modelo Groot foi selecionado devido ao menor erro quadrático médio das predições (0,29% de N total perdido como NH3). A maior volatilização de NH3 ocorreu em condições climáticas úmida, seguido por intermediária e seca (20,2; 17,0 e 11,3% de N total perdido como NH3, respectivamente). Portanto, as perdas de N como volatilização de NH3 após a aplicação de 50 kg N ha-1, como fonte de ureia, são alteradas de acordo com as condições climáticas, atingindo a 20% do N adicionado nas condições úmidas. O modelo Groot é recomendado para ajuste e estimativa da volatilização de NH3 da ureia aplicada em pastos de capim Marandu em condições úmidas e secas.

Abstract: En | Text: En | PDF: En

ABSTRACT Rice (Oryza sativa) is among the most important crops worldwide; however, rice crops demand high water consumption. Future projections indicate reduced water availability and severe drought events, which may affect rice crops as the cereal is highly sensitive to drought stress. Thus, cultivars with lower water demand for irrigation or drought escape capacities are among the strategies to address this issue. This study aimed to assess five mutant rice genotypes in terms of growth cycle length, other agronomic interest traits, and drought response in the reproductive stage. The mutant genotypes evaluated showed a shortening of the growth cycle compared to the original cultivar, BRS Pampeira, representing a drought escape strategy. In addition, mutations did not negatively affect plant height and crop yield. However, similar to the original cultivar, mutants are not tolerant to water deficit in the reproductive stage. The genotypes evaluated have potential to be released as early cycle cultivars, which can reduce water demand during the harvest season while presenting a drought escape strategy. Oryza sativa worldwide however consumption events stress Thus issue length traits stage cultivar Pampeira strategy addition yield However

Abstract Background Anti-myelin oligodendrocyte glycoprotein (anti-MOG) antibody-associated disease (MOGAD) is an immune-mediated neurological disorder with a broad spectrum of clinical presentation that is often difficult to distinguish from other demyelinating diseases, such as multiple sclerosis and neuromyelitis optica spectrum disorder. Objective To describe the clinical and paraclinical characteristics of MOGAD in a Brazilian tertiary center. Methods We retrospectively reviewed the records of adult and pediatric patients who tested positive for anti-MOG antibodies and presented with clinical and radiological diseases compatible with MOGAD. Results Forty-one patients (10 children) were included: 56% female, 58% Caucasian, mean age at onset 31 years (range 6-64), with a mean disease duration of 59.6 months (range 1-264 months). The most frequent onset presentation was optic neuritis (68%), acute disseminated encephalomyelitis (ADEM, 12%), and myelitis (10%). A monophasic disease course was observed in 49%. EDSS median was 2.1 at the last visit. Most patients (83%) were under continuous immunosuppressive treatment. Azathioprine was the first-line treatment in 59%. In all ADEM cases, conus, and root involvement was radiologically observed on MRI. Conclusion Brazilian MOGAD patients presented with a similar spectrum of previously reported MOGAD phenotypes. Conus and spinal root involvement seems to be frequently present in MOGAD-ADEM and could serve as radiologic characteristics of this clinical entity.

Resumo Antecedentes A doença associada ao anticorpo da glicoproteína da mielina de oligodendrócitos (anti-MOG; MOGAD) é uma doença neurológica imunomediada com um amplo espectro de apresentações clínicas que muitas vezes é difícil de distinguir de outras doenças desmielinizantes, como a esclerose múltipla e o distúrbio do espectro da neuromielite óptica. Objetivo Descrever as características clínicas e paraclínicas da MOGAD em um centro terciário brasileiro. Métodos Revisamos retrospectivamente os prontuários dos pacientes adultos e pediátricos que testaram positivos para anticorpos anti-MOG e apresentaram um quadro clínico e radiológico compatível com MOGAD. Resultados Quarenta e um pacientes (10 crianças) foram incluídos: 56% do sexo feminino, 58% caucasianos, idade média de início da doença foi 31 anos (intervalo de 6-64), com duração média da doença de 59,6 meses (intervalo de 1-264 meses). A apresentação inicial mais frequente foi neurite óptica (68%), seguida pela encefalomielite disseminada aguda (ADEM, 12%) e mielite (10%). Um curso monofásico da doença foi observado em 49%. EDSS foi de 2,1 na última visita. A maioria dos pacientes (83%) estava sob tratamento imunossupressor contínuo. Azatioprina foi o tratamento de primeira linha em 59%. Em todos os casos de ADEM, o envolvimento do cone medular e das raízes espinhais foi observado radiologicamente na ressonância magnética. Conclusão Os pacientes brasileiros com MOGAD apresentam um espectro clínico e radiológico semelhante aos fenótipos de MOGAD relatados anteriormente. O envolvimento do cone e das raízes espinhais parece estar frequentemente presente no MOGAD-ADEM e poderia servir como característica radiológica nesta entidade.

Abstract: En | Text: En | PDF: En

The objective of this paper was to evaluate the kinetics of the hydrolysis of soybean oil by the action of the Lipozyme® TL IM enzyme varying the operational conditions of molar ratio water/oil (9:1-60:1) and temperature (40-64 °C). To describe the experimental data, a mathematical model based on the kinetic mechanism of Ping-Pong Bi Bi (PPBB) was proposed, in which the following steps were not considered formation of the complex enzyme/oil substrate, and formation of the acylated enzyme/oil substrate complex. The results of enzymatic hydrolysis of soybean oil indicated a yield in free fatty acids of 76% at the molar ratio of 46:1 and temperature of 52 °C. Furthermore, based on the values of the determination coefficient and root mean square error, the mathematical model based on the kinetic mechanism of PPBB showed good agreement with the experimental data in a relatively wide temperature range. Thus, it can be a useful tool for the optimization and assessment of the mechanisms of enzymatic hydrolysis of vegetable oil.

Abstract: En Es

Aedes aegypti mosquitoes are the main vector of human arbovirosis in tropical and subtropical areas.  Its adaptation to urban and rural environments generates infestations inside households. Therefore, entomological surveillance in association with spatio-temporal analysis is an innovative approach to vector control and dengue management. The main aim was to inspect immature pupal stages in households belonging to municipalities at high risk of dengue in Cauca, Colombia by implementing entomological indices and relating how they influence adult mosquito density. Here, we provide novel data for the geographical distribution of 3,806 immature pupal stages of Ae. aegypti. We also report entomological indices and spatial characterization. The results suggest that for Ae. aegypti species, pupal productivity generates high densities of adults in neighbouring households, evidencing seasonal behaviour. This dataset is of great importance as it provides an innovative strategy for vector-borne disease mitigation using vector spatial patterns and their association with entomological indicators and breeding sites in high-risk neighbourhoods.

Los mosquitos Aedes aegypti son el principal vector de las arbovirosis humanas en zonas tropicales y subtropicales. Su adaptación a entornos urbanos y rurales genera infestaciones en el intradomicilio de las viviendas. De aquí que, la vigilancia entomológica en asociación con el análisis espacial y el análisis espacio-temporal sean un enfoque innovador para el control de vectores y la gestión del dengue.El objetivo principal de la investigación fue realizar una comparación de la vigilancia entomológica, mediante el uso de índices cuantitativos de pupas y de adultos en tres municipios de alto riesgo de dengue Patía (El Bordo), Miranda y Piamonte del departamento del Cauca, con el fin de examinar cómo influye la productividad de pupas, entre índices entomológicos, en la densidad de mosquitos adultos y otros patrones espaciales y temporales. Ae. aegypti , sus índices entomológicos y su caracterización espacial. Los resultados sugieren que, para las especies de Ae. aegypti , la productividad de pupas genera altas densidades de adultos en las viviendas vecinas, evidenciando un comportamiento estacional.Estos resultados son de gran importancia ya que proporciona una estrategia innovadora para la mitigación de enfermedades transmitidas por vectores utilizando patrones espaciales de los vectores y su asociación con indicadores entomológicos y lugares de cría en barrios de alto riesgo para la transmisión del dengue.

Resumo A doença de Crohn e a colite ulcerativa são Doenças Inflamatórias Intestinais (DII) caracterizadas por períodos de atividade e remissão, às vezes com grande comprometimento funcional e, portanto, podem estar associadas a sintomas psicológicos e estigmatização dos pacientes. O objetivo deste estudo foi identificar os principais fatores associados à ansiedade e depressão em pacientes com DII. O aspecto psicológico foi analisado por meio de dois questionários validados globalmente - o Patient Health Questionnaire (PHQ-9) e o General Anxiety Disorder (GAD-7) - além de um questionário sociodemográfico, aplicado em três grupos, cada um composto por 100 indivíduos, o primeiro para pacientes ambulatoriais com diagnóstico de DII, o segundo para pacientes ambulatoriais sem diagnóstico de DII e o terceiro para indivíduos saudáveis. Os pacientes com DII apresentaram maior frequência de indicadores positivos para ansiedade (55%) e depressão (42%) em comparação com os outros grupos (p<0,05). Além disso, os indivíduos do grupo com DII também apresentaram graus mais intensos de ansiedade e depressão do que os demais grupos (p<0,05). Os principais fatores relacionados à maior prevalência de ansiedade e depressão foram menor frequência de trabalho estável, maior frequência da classe social E, além de autopercepção de não ser saudável (p<0,05). Aqueles que foram diagnosticados com DII com menos de dois anos de sintomas apresentaram menos depressão e a maioria dos que tem ansiedade e depressão não usa ansiolíticos e antidepressivos.

Abstract Crohn's disease and ulcerative colitis are Inflammatory Bowel Diseases (IBD) characterized by periods of activity and remission, sometimes with major functional impairment, and thus may be associated with psychological symptoms and stigmatization of patients. The purpose of this study was to identify the main factors associated with anxiety and depression in patients with (IBD). The psychological aspect was analyzed using two globally validated questionnaires - the Patient Health Questionnaire (PHQ-9) and the General Anxiety Disorder questionnaire (GAD-7) - in addition to a sociodemographic questionnaire, which were applied to three groups, each composed by 100 individuals, the first for outpatients diagnosed with IBD, the second for outpatients without IBD diagnosis and the third for healthy individuals. IBD patients had a higher frequency of positive indicators for anxiety (55%) and depression (42%) compared to the other groups (p<0.05), in addition, individuals in the IBD group also had more intense degrees of anxiety and depression than the other groups (p<0.05). The main factors related to the higher prevalence of anxiety and depression were lower frequency of steady job, higher frequency of social class E, as well as having self-perception of unhealthy (p<0.05). Those who were diagnosed with IBD with less than two years of symptoms had less depression and most who have anxiety and depression do not use anxiolytics and antidepressants.

ABSTRACT Zinc (Zn) is an essential nutrient for plants, and there is limited information on its availability in Paraguayan soils. The objective of the research was to evaluate and classify the availability of Zn in soils of the Eastern region of Paraguay. For this, a database was generated with the results of soil analyses from the FCA-UNA, CIHB-IPTA and FUCAI-UCA laboratories. The concentration of available Zn in soils was classified as "high" (>1.2 mg kg-1); “medium” (0.5 - 1.2 mg kg-1) and “low” (<0.5 mg kg-1), generating a Zn availability map at the district level. The availability of Zn was evaluated at the district and departmental levels, as well as with descriptive statistics parameters. Considering the average Zn levels at the district level, of the 234 districts that make up the Eastern region of Paraguay, 74% of the districts (174 districts) presented a "high" level, 6% a "medium" level (15 districts) and 3% “low” level of Zn (6 districts). Considering the total number of soil samples analyzed (11,395 samples), 79% (9,038 samples) presented "high" levels of Zn, 12% (1,316 samples) presented "medium" levels of Zn, and only 9% (1,041 samples) presented “low” levels of Zn. The national average, considering the 11,395 soil samples, was 6.5 mg kg-1 of Zn, therefore, in 79% of the soils analyzed in the Eastern region there are Zn levels above the critical level of Zn for agricultural activities, forage and forestry production.

Abstract Background Professional soccer athletes are exposed to repetitive head impacts and are at risk of developing chronic traumatic encephalopathy. Objective To evaluate regional brain glucose metabolism (rBGM) and gray matter (GM) volume in retired soccer players (RSPs). Methods Male RSPs and age and sex-matched controls prospectively enrolled between 2017 and 2019 underwent neurological and neuropsychological evaluations, brain MRI and [18F]FDG-PET in a 3.0-Tesla PET/MRI scanner. Visual analysis was performed by a blinded neuroradiologist and a blinded nuclear physician. Regional brain glucose metabolism and GM volume were assessed using SPM8 software. Groups were compared using appropriate statistical tests available at SPM8 and R. Results Nineteen RSPs (median [IQR]: 62 [50–64.5] years old) and 20 controls (60 [48–73] years old) were included. Retired soccer players performed worse on mini-mental state examination, digit span, clock drawing, phonemic and semantic verbal fluency tests, and had reduced rBGM in the left temporal pole (pFDR = 0.008) and the anterior left middle temporal gyrus (pFDR = 0.043). Semantic verbal fluency correlated with rBGM in the right hippocampus, left temporal pole, and posterior left middle temporal gyrus (p ≤ 0.042). Cray matter volume reduction was observed in similar anatomic regions but was less extensive and did not survive correction for multiple comparisons (pFDR ≥ 0.085). Individual [18F]FDG-PET visual analysis revealed seven RSPs with overt hypometabolism in the medial and lateral temporal lobes, frontal lobes, and temporoparietal regions. Retired soccer players had a higher prevalence of septum pellucidum abnormalities on MRI. Conclusion Retired soccer players had reduced rBCM and CM volume in the temporal lobes and septum pellucidum abnormalities, findings possibly related to repetitive head impacts.

Objetivo Avaliar o metabolismo glicolítico cerebral regional (MCCr) e o volume de substância cinzenta (vSC) em jogadores de futebol aposentados (JFAs). Métodos Jogadores de futebol aposentados masculinos e controles pareados por idade e sexo foram incluídos prospectivamente entre 2017 e 2019. Foram realizadas avaliações neurológica e neuropsicológica, ressonância magnética (RM) e [18F]FDG-PET cerebrais (3.0-Tesla PET/RM). As imagens foram analisadas visualmente por um neurorradiologista e um médico nuclear cegos ao grupo de cada participante. O metabolismo glicolítico cerebral regional e o vSC foram avaliados através do programa SPM8. Os grupos foram comparados através de testes estatísticos apropriados disponíveis em SPM8 e R, de acordo com a distribuição e o tipo dos dados. Resultados Dezenove JFAs (mediana [IIQ]: 62 [50–64.5] anos) e 20 controles (60 [48–73] anos) foram incluídos. Os JFAs tiveram pior desempenho no mini-exame do estado mental e nos testes de dígitos, desenho do relógio, fluência verbal e fluência semântica e apresentaram MCCr significativamente reduzido no polo temporal e no giro temporal médio anterior esquerdos. Fluência semântica (animais) apresentou correlação positiva com MCCr no hipocampo direito, no polo temporal esquerdo e no aspecto posterior do giro temporal médio esquerdo. Menor vSC foi observado nas mesmas regiões, porém este achado não sobreviveu à correção para comparações múltiplas. Análise individual do [18F]FDG-PET cerebral revelou sete JFAs com claro hipometabolismo nas faces medial e lateral dos lobos temporais, nos lobos frontais e nas regiões temporoparietais. Os JFAs apresentaram ainda maior prevalência de anormalidades do septo pelúcido. Conclusão Os JFAs apresentam MCCr e vSC reduzidos nos lobos temporais, além de anormalidades do septo pelúcido, achados possivelmente relacionados a impactos cranianos repetitivos.

Abstract The zoanthid Palythoa caribaeorum secretes a large quantity of mucus that acts as a substrate for microbial communities. Culturable bacteria associated with P. caribaeorum mucus in northeastern Brazil were evaluated through 16S rRNA gene sequences. Proteobacteria was the dominant group, followed by Actinobacteria and Firmicutes. Vibrio was the most common genus, although other groups with the ability to produce biosurfactants and compounds with antimicrobial activity were also present. The studies of culturable marine bacteria may contribute to the understanding of the associated microbial community, opening new opportunities to explore biotechnological potential of microbiota.

Abstract Sheep production systems face numerous challenges, which make decision-making a process fraught with risks and uncertainties. Modelling is a helpful tool in this respect, as it allows decision-makers to evaluate the behaviour of variables and their interrelationships, in addition to using previous or related information to predict results and simulate different scenarios. The advent of prediction models has made it possible to monitor the weight of an animal and determine the best time for its sale. Additionally, it allows producers to estimate the weights of the carcass and major marketable cuts before slaughter. All this information is directly associated with the profitability and success of the production activity. Therefore, in view of the different applications of mathematical models in production systems, this literature review examines concepts in modelling studies and the importance of using prediction models in meat sheep production. Furthermore, it addresses the practical application of modelling studies in predicting dry matter intake and carcass traits of meat sheep through correlated variables.

Resumen Los sistemas de producción ovina se enfrentan a numerosos desafíos, que hacen de la toma de decisiones un proceso lleno de riesgos e incertidumbres. En este sentido, la modelación es una herramienta útil, ya que permite a los tomadores de decisiones evaluar el comportamiento de las variables y sus interrelaciones, además de utilizar información previa o relacionada para predecir resultados y simular diferentes escenarios. El advenimiento de los modelos de predicción ha permitido monitorear el peso de un animal y determinar el mejor momento para su venta. Además, permite a los productores estimar los pesos de la canal y los principales cortes comercializables antes del sacrificio. Toda esta información está directamente asociada a la rentabilidad y el éxito de la actividad productiva. Por lo tanto, en vista de las diferentes aplicaciones de los modelos matemáticos en los sistemas de producción, esta revisión de la literatura examina los conceptos en los estudios de modelación y la importancia de utilizar modelos de predicción en la producción de ovinos de carne. Además, aborda la aplicación práctica de los estudios de modelación en la predicción de la ingesta de materia seca y los rasgos de la canal de ovinos de carne a través de variables correlacionadas.
