Resumo A atividade antioxidante do mel de Tetragonisca angustula (TAH) e seu extrato etanólico (TAEE) foram investigados. Os níveis totais de fenólicos (TPC) e flavonóides (TFC) também foram avaliados. Os resultados para TPC foram 19,91 ± 0,38 e 29,37 ± 1,82 mg GAE g-1 e para TFC 0,20 ± 0,02 e 0,14 ± 0,01 mg QE g-1 de TAH e TAEE, respectivamente. As atividades antioxidantes foram 73,29 ± 0,49% e 93,36 ± 0,27% no ensaio DPPH● e 71,73 ± 4,07% e 97,86 ± 0,35% no ABTS●+ para TAH e TAEE, respectivamente. A atividade redutora total foi determinada pelo método de poder redutor (PR) e íon ferrico (Fe III) e os resultados variaram em PR de 151,7 ± 25,7 e 230,7 ± 25,2 mg GAE L-1, para TAH e TAEE respectivamente e para (Fe III) em EC50 0,284 em TAEE e 0,687 em TAH. A análise química por HPLC-DAD do extrato etanólico (TAEE) revelou a presença de ácido ferúlico como componente majoritário no extrato. A análise de RMN 1H confirmou esta estrutura e mostrou a presença de glicose, ácido cítrico, ácido succínico, prolina e derivados de hidrocarbonetos no TAEE. Além disso, a origem botânica também foi investigada e apresentou característica multifloral, tendo encontrado 19 tipos polínicos com predomínio botânico da família Anacardiaceae, sendo o pólen Tapirira predominante (42,6%) e o Schinus secundário (25,7%). Os resultados mostraram que o mel de T. angustula é uma interessante fonte de compostos fenólicos antioxidantes devido à sua origem floral e pode atuar como protetor da saúde humana quando consumido.
Abstract The antioxidant activity of Tetragonisca angustula honey (TAH) and its ethanolic extract (TAEE) were investigated. The total levels of phenolic (TPC) and flavonoids (TFC) were also evaluated. The results for TPC were 19.91 ± 0.38 and 29.37 ± 1.82 mg GAE g-1 and for TFC 0.20 ± 0.02 and 0.14 ± 0.01 mg QE g-1 of TAH and TAEE, respectively. Antioxidant activities were 73.29 ± 0.49% and 93.36 ± 0.27% in the DPPH● assay and 71.73 ± 4.07% and 97.86 ± 0.35% in ABTS●+ for TAH and TAEE, respectively. The total reducing activity was determined by the method of reducing power (PR) and iron ion (Fe III) and the results varied in PR from 151.7 ± 25.7 and 230.7 ± 25.2 mg GAE L-1, for TAH and TAEE respectively and for (Fe III) in EC50 0.284 in TAEE and 0.687 in TAH. Chemical analysis by HPLC-DAD of the ethanolic extract (TAEE) revealed the presence of ferulic acid as majority phenolic component in the extract. The 1H NMR analysis confirmed this structure and showed the also presence of glucose, citric acid, succinic acid, proline and hydrocarbon derivatives. In addition, the botanical origin was also investigated and showed a multifloral characteristic, having found 19 pollen types with a botanical predominance of the Anacardiaceae family, with Tapirira pollen occurring as predominant (42.6%) and Schinus as secondary (25.7%). The results showed that T. angustula honey is an interesting source of antioxidant phenolic compounds due to its floral origin and can act as a protector of human health when consumed.

RESUMO As fontes hídricas do semiárido brasileiro comumente apresentam altos teores de sais dissolvidos em sua composição, destacando-se como um dos estresses abióticos que limita a expansão da fruticultura irrigada, principalmente de culturas sensíveis ao estresse salino como o maracujazeiro-azedo. Assim, a utilização de substâncias elicitoras, como prolina, pode ser uma alternativa eficaz para mitigar o estresse salino nas plantas. Nesse contexto, objetivouse com este trabalho avaliar os efeitos da aplicação foliar de prolina na fluorescência da clorofila, crescimento, qualidade e tolerância de maracujazeiro-azedo irrigados com águas salinas durante a fase de formação de mudas. A pesquisa foi conduzida no período de julho a outubro de 2022, em casa de vegetação em Campina Grande - PB, utilizando-se o delineamento inteiramente casualizado, em esquema fatorial 5 × 4, sendo cinco níveis de condutividade elétrica da água de irrigação CEa - (0,6; 1,2; 1,8; 2,4 e 3,0 dS m-1) e quatro concentrações de prolina (0, 5, 10 e 15 mM) com quatro repetições e duas plantas por parcela. A salinidade da água a partir de 0,6 dS m-1 reduz a fluorescência máxima, variável, eficiência quântica do fotossistema II e o crescimento de mudas maracujazeiro-azedo ‘BRS GA1’. A aplicação foliar de prolina em concentração variando de 6 a 8,05 mM aumenta o crescimento em altura de plantas, diâmetro de caule e área foliar de mudas de maracujazeiro-azedo. O genótipo de maracujazeiro-azedo ‘BRS GA1’ é sensível a salinidade da água, sendo o nível de salinidade limiar de 0,6 dS m-1 e a redução por aumento unitário da condutividade elétrica de 10,49%. composição destacandose destacando se irrigada maracujazeiroazedo. maracujazeiroazedo maracujazeiro azedo. azedo Assim elicitoras contexto clorofila 2022 PB utilizandose utilizando casualizado 4 06 0 (0,6 1,2 12 1 2 1,8 18 8 24 2, 30 3 3, m1 m 0, (0 parcela m- máxima variável BRS GA1.

ABSTRACT Water sources in the Brazilian semi-arid region commonly contain high levels of dissolved salts in their composition, standing out as one of the abiotic stresses that limit the expansion of irrigated fruit growing, especially salt stress-sensitive crops such as sour passion fruit. Thus, the use of elicitors, such as proline, can be an effective alternative to mitigate salt stress in plants. In this context, the objective of this study was to evaluate the effects of foliar application of proline on chlorophyll fluorescence, growth, quality and tolerance of sour passion fruit irrigated with saline water during the seedling formation phase. The experiment was conducted from July to October 2022, under greenhouse conditions in Campina Grande, PB, Brazil, using a completely randomized design, in a 5 × 4 factorial scheme, with five levels of electrical conductivity of irrigation water - ECw (0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1) and four concentrations of proline (0, 5, 10 and 15 mM), with four replicates and two plants per plot. Water salinity from 0.6 dS m-1 reduces the maximum fluorescence, variable fluorescence, quantum yield of photosystem II and growth of ‘BRS GA1’ sour passion fruit seedlings. Foliar application of proline at concentrations ranging from 6 to 8.05 mM increases the growth in plant height, stem diameter and leaf area of sour passion fruit seedlings. The sour passion fruit genotype ‘BRS GA1’ is sensitive to water salinity, with a salinity threshold level of 0.6 dS m-1 and a reduction per unit increase in electrical conductivity of 10.49%. semiarid semi arid composition growing stresssensitive Thus elicitors context fluorescence phase 2022 Grande PB Brazil design scheme 0.6, 06 0 (0.6 12 1 2 1.2 18 8 1.8 24 2. 30 3 3. m1 m 0, (0 mM, , mM) plot 0. m- BRS GA1 GA seedlings 805 05 8.0 height 1049 49 10.49% 202 (0. 1.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

ABSTRACT Salt stress is one of the main abiotic factors responsible for limiting agricultural production worldwide, especially in regions with a semi-arid climate, where climatic conditions intensify the effect of salts on plants. The objective of this study was to evaluate the mineral composition of sour passion fruit plants grown under irrigation with saline water and potassium fertilization in a semi-arid region of Brazil. The experiment was carried out under field conditions in São Domingos, PB, Brazil. A randomized block design was adopted, in a 5 × 4 factorial scheme, with five levels of electrical conductivity of irrigation water - ECw (0.3, 1.1, 1.9, 2.7 and 3.5 dS m-1) and four potassium doses - KD (60, 80, 100 and 120% of the K2O recommendation) with 3 replicates. There was an increase in sodium and chloride contents in the stem and leaves of sour passion fruit plants with the increase in ECw levels. Fertilization with 120% of the K2O recommendation associated with irrigation using water with EC of up to 1.1 and 1.6 dS m-1 increased potassium content in the stem and leaves and leaf nitrogen content, respectively, in ‘BRS Sol do Cerrado’ sour passion fruit plants. Fertilization with 60% of the K2O recommendation increased phosphorus content in the leaves of sour passion fruit plants under water salinity of up to 2.2 dS m-1. In the leaves, nutrient contents varied according to the order of concentration N>Cl>P>Na>K, while in the stem the order was N>Cl>P>Na>K, at 160 days after transplanting. worldwide semiarid semi arid climate Brazil Domingos PB adopted scheme 0.3, 03 0 (0.3 11 1 19 9 1.9 27 2 7 2. 35 3. m1 m 60, 60 (60 80 10 120 KO K O replicates 1. 16 6 m- respectively BRS Cerrado 22 m1.

RESUMO A escassez qualitativa e quantitativa das fontes hídrica é uma realidade no semiárido brasileiro e restringe a expansão das áreas irrigadas. Desta forma, é de suma importância buscar estratégias para viabilizar a produção de fruteiras como o maracujazeiro-azedo. Nesse sentido, objetivou-se com este estudo avaliar os efeitos da aplicação foliar de peróxido de hidrogênio na homeostase iônica do maracujazeiro-azedo cv. BRS Rubi do Cerrado sob irrigação com águas salinas. O experimento foi desenvolvido em lisímetros de drenagem sob condições de casa de vegetação em Campina Grande – PB. O delineamento foi inteiramente casualizado em parcelas subdivididas, sendo cinco níveis de condutividade elétrica da água - CEa (0,6, 1,2, 1,8, 2,4 e 3,0 dS m-1) consideradas as parcelas e quatro concentrações de peróxido de hidrogênio – H2O2 (0, 15, 30 e 45 µM) as subparcelas, com três repetições. Os teores de sódio nas folhas reduziram nas plantas submetidas à aplicação de 45 µM de H2O2. As relações N/P e N/Na na folha do maracujazeiro-azedo cv. BRS Rubi do Cerrado reduziram com o aumento da salinidade da água de irrigação a partir de 2,76 e 2,03 dS m-1 respectivamente.

ABSTRACT Qualitative and quantitative scarcity of water sources is a reality in the Brazilian semi-arid region and restricts the expansion of irrigated areas in this region, where high levels of soluble salts are common. Thus, it is extremely important to seek strategies to enable the production of fruit crops such as sour passion fruit. In this context, the objective of this study was to evaluate the levels of NPK, Na+ and Cl- in leaf and stem tissues of sour passion fruit cv. BRS Rubi do Cerrado as a function of irrigation with saline water and exogenous application of hydrogen peroxide. The experiment was carried out in drainage lysimeters under greenhouse conditions in Campina Grande, PB, Brazil. The design was completely randomized in split plots, with five levels of electrical conductivity of water - ECw (0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1) considered plots and four concentrations of hydrogen peroxide – H2O2 (0, 15, 30 and 45 µM) considered subplots, with three repetitions. Sodium content in the leaves decreased when the H2O2 concentration of 45 µM was applied. N/P and N/Na ratios in the leaves of sour passion fruit cv. BRS Rubi do Cerrado decreased with the increase in irrigation water salinity from 2.76 and 2.03 dS m-1, respectively. Chloride content in the leaves of sour passion fruit increased as a function of irrigation water salinity, regardless of H2O2 application. semiarid semi arid common Thus context NPK Na Cl cv Grande PB Brazil 0.6, 06 0 6 (0.6 12 1 2 1.2 18 8 1.8 24 4 2. 3 3. m1 m m-1 HO H O H2O 0, (0 15 subplots repetitions applied NP N P NNa 276 76 2.7 203 03 2.0 m1, 1, respectively 0.6 (0. 1. m- ( 27 7 20 0.

RESUMO O sucesso do cultivo de maracujazeiro amarelo na região semiárida do Nordeste brasileiro está condicionado à capacidade da cultura em desenvolver-se sob condições de estresse salino, fazendo-se necessário identificar técnicas capazes de amenizarem os efeitos deletérios ocasionados pela irrigação com águas de elevada salinidade. Neste contexto, objetivou-se avaliar a fluorescência, pigmentos fotossintéticos e biomassa de maracujazeiro amarelo cultivado sob estresse salino e aplicação foliar de peróxido de hidrogênio. A pesquisa foi conduzida em casa de vegetação, com o delineamento experimental de blocos casualizados com três repetições, em esquema fatorial 4 × 4, os quais consistiram de quatro valores de condutividade elétrica da água de irrigação - CEa (0,7; 1,4; 2,1 e 2,8 dS m-1) e quatro concentrações de peróxido de hidrogênio (0, 20, 40 e 60 µM). A irrigação com água de CEa a partir de 1,4 dS m-1 comprometeu a eficiência fotoquímica, os pigmentos fotossintéticos e a produção de fitomassa do maracujazeiro amarelo. A aplicação de peroxido de hidrogênio na concentração de 20 µM promoveu os maiores valores para fluorescência variável e máxima e conteúdo de carotenoides constituindo-se como alternativa para aclimatação do maracujazeiro ao estresse salino. A aplicação de peroxido de hidrogênio em concentração superior a 20 µM intensificou o estresse salino sobre o maracujazeiro.
ABSTRACT The success of yellow passion fruit cultivation in the semi-arid region of Northeast Brazil is conditioned on the ability of this crop to develop under salt stress conditions, so it is necessary to identify techniques capable of attenuating the deleterious effects caused by irrigation with high-salinity waters. In this context, the present study aimed to evaluate the fluorescence, photosynthetic pigments and biomass of yellow passion fruit cultivated under salt stress and foliar application of hydrogen peroxide. The study was conducted in a greenhouse, with the experimental design in randomized blocks with three replicates, in a 4 × 4 factorial scheme, which consisted of four values of irrigation water electrical conductivity - ECw (0.7, 1.4, 2.1 and 2.8 dS m-1) and four concentrations of hydrogen peroxide (0, 20, 40 and 60 µM). Irrigation using water with ECw from 1.4 dS m-1 compromised the photochemical efficiency, photosynthetic pigments, and biomass production of yellow passion fruit. Application of hydrogen peroxide at concentration of 20 µM promoted the highest values for variable and maximum fluorescence and concentration of carotenoids, constituting an alternative for the acclimation of yellow passion fruit to salt stress. Application of hydrogen peroxide at concentrations above 20 µM intensified the salt stress on passion fruit.

RESUMO Para estudos de desempenho térmico, a modelagem computacional tem sido apresentada como uma importante ferramenta na tomada de decisões para solucionar problemas complexos e cotidianos na produção e pesquisa em avicultura. Desta forma, o presente estudo teve como objetivo validar modelos computacionais desenvolvidos por meio do programa EnergyPlus e a partir destes avaliar o desempenho térmico de um aviário com diferentes tipos de telhas (termoacústicas, cerâmicas, fibrocimento e metálicas). A pesquisa consistiu em duas etapas: uma fase experimental e outra fase para a simulação computacional das condições climáticas em quatro modelos de aviário, considerando diferentes tipos de telhas. A fase experimental foi conduzida em duas estações climáticas, inverno (2019) e verão (2020), onde foram aferidos e registrados os dados de temperatura e umidade relativa do ar através de seis data loggers HOBO modelo H12, distribuídos no interior de um aviário localizado no semiárido pernambucano. Para a simulação computacional, foi desenvolvido um modelo virtual do galpão com auxílio da interface gráfica de usuário OpenStudio no Sketchup, e posteriormente o cálculo do desempenho térmico foi realizado por meio do software EnergyPlus. A validação dos modelos mostrou uma forte correlação entre os dados obtidos de maneira experimental e os simulados, apresentando valores do coeficiente de correlação de Pearsons (r) maiores que 0.95. As simulações demonstraram a influência das telhas no desempenho térmico da edificação avaliada, onde para as condições climáticas do semiárido pernambucano, o melhor desempenho térmico foi apresentado pelas telhas termoacústicas, seguido das telhas cerâmicas, de fibrocimento e metálicas.
ABSTRACT For studies of thermal performance, computational modeling has been presented as an important decision-making tool to solve complex and everyday problems in poultry production and research. Thus, the present study aimed to validate computational models developed using the EnergyPlus software package and, based on these, evaluate the thermal performance of a poultry house with different types of tiles (thermoacoustic, ceramic, fiber-cement, and metal). The research consisted of two stages: an experimental phase and another phase in which the climatic conditions in four aviary models are numerically simulated, considering different types of tiles. The experimental phase was conducted in two climate seasons, winter (2019) and summer (2020), where air temperature and relative air humidity data were measured and recorded using six HOBO model H12 data loggers distributed inside an aviary located in the semiarid region of Pernambuco state, Brazil. For the computer simulation, a virtual model of the house was developed using the OpenStudio graphical user interface in Sketchup, and the thermal performance was calculated using the EnergyPlus software package. The models were validated, showing a strong correlation between the experimental and simulated data, with Pearson’s correlation coefficient (r) values greater than 0.95. The simulations demonstrated the influence of the roof tiles on the thermal performance of the evaluated building. For the climatic conditions of the semiarid region of the Pernambuco state, thermoacoustic roof tiles presented the best thermal performance, followed by ceramic, fiber-cement, and metal roof tiles.

RESUMO A ocorrência de fontes hídricas com elevada concentração de sais se destaca como fator limitante para a produção no Nordeste brasileiro. Assim, é de fundamental importância a busca por estratégias que minimizem o efeito do estresse salino nas culturas. Neste contexto, desenvolveu-se esta pesquisa com o objetivo de avaliar a produção e a qualidade pós-colheita de frutos de mini-melancia Sugar Baby sob diferentes estratégias de manejo de irrigação com água salina e adubação potássica. O experimento foi conduzido em casa de vegetação, utilizando-se o delineamento de blocos casualizados, em esquema fatorial 8 × 3, com três repetições, sendo oito estratégias de manejo da irrigação com águas salinas (Sem estresse ao longo do ciclo da cultura; irrigação com água salina na fase vegetativa, vegetativa/floração, floração, floração/frutificação, frutificação, frutificação/maturação e maturação dos frutos) e três doses de potássio (50, 100 e 150% da dose recomendada). A dose de 100% correspondeu a 150 mg K2O kg-1 de solo. Utilizou-se água com baixa e outra com alta condutividade elétrica (0,8 e 4,0 dS m-1, respectivamente). A irrigação com água de 4,0 dS m-1 nas fases de floração e maturação dos frutos é uma estratégia promissora para o cultivo de mini-melancia, pois não compromete sua produção. Adubação com 50% da recomendação de K2O pode ser utilizada no cultivo de mini-melancieira sem perda no rendimento. As plantas de mini-melancieira adubadas com 150% da recomendação de K2O e irrigadas com água de elevada concentração de sais nas fases vegetativa/floração de forma continua e frutificação diminuíram os teores de sólidos solúveis e ácido ascórbico nos frutos.
ABSTRACT The occurrence of water sources with a high concentration of salts stands out as a limiting factor for production in Northeast Brazil. Thus, the search for strategies that minimize the effect of salt stress on crops is of fundamental importance. In this context, this study was conducted with the objective of evaluating the production and post-harvest quality of Sugar Baby mini-watermelon fruits under different irrigation management strategies with saline water and potassium fertilization. The experiment was conducted in a greenhouse, using a randomized block design, in an 8 × 3 factorial scheme, with three replicates, corresponding to eight saline water irrigation management strategies (No stress throughout the crop cycle; irrigation with saline water in the vegetative, vegetative/flowering, flowering, flowering/fruiting, fruiting, fruiting/maturation and fruit maturation stages) and three doses of potassium (50, 100 and 150% of the recommended dose). The dose of 100% corresponded to 150 mg K2O kg-1 of soil. Water with low and with high electrical conductivity (0.8 and 4.0 dS m-1, respectively) was used. Irrigation with water of 4.0 dS m-1 in the flowering and fruit maturation stages is a promising strategy for the cultivation of mini-watermelon, as it does not compromise production. Fertilization with 50% of K2O recommendation can be used in the cultivation of mini-watermelon without losses in yield. Mini-watermelon plants fertilized with 150% of K2O recommendation and irrigated with water of high salt concentration continuously in the vegetative/flowering and fruiting stages reduced the contents of soluble solids and ascorbic acid in the fruits.

Resumo Ensaios práticos de enzimas para detectar contaminação subletal de peixes neotropicais são da maior importância. Assim, ensaiamos a atividade da glutationa S-transferase (GST) em citosóis de fígado e de rim de Piaractus mesopotamicus injetados com metilparation ou benzo[a]pireno usando 1-cloro-2,4-dinitrobenzeno (CDNB), o substrato usual para ensaiar uma denominada atividade geral de GST. Desde que para indicar alterações na atividade de uma isoenzima, é necessário o substrato mais reativo, também usamos dois substratos alternativos, o 1,2-dicloro-4-nitrobenzeno (DCNB) e o ácido etacrínico (ETHA). As atividades com CDNB ou ETHA não mudaram. Entretanto, ensaios com DCNB mostraram que metilparation decresceu a atividade de GST no fígado em 24, 48 e 96 horas depois da injeção. O DCNB também revelou que sete dias depois da injeção de benzo[a]pireno a atividade da GST aumentou no fígado, normalizando depois de 14 dias. Benzo[a]pireno, mas não metilparation, aumentou as atividades com DCNB no citosol dos rins sete e 14 dias depois da injeção. Assim, uma atividade de GST ensaiada com DCNB diminuída no fígado correspondeu à contaminação de P. mesopotamicus com metilparation. O aumento dessa atividade de GST no fígado e nos rins está correlacionada com contaminação do pacu por hidrocarbonetos policíclicos aromáticos.
Abstract Functional enzyme assays to detect sublethal poisoning of Neotropical fish are paramount. Accordingly, we assayed a glutathione S-transferase (GST) activity in liver and kidney cytosols from Piaractus mesopotamicus injected with methyl parathion or benzo[a]pyrene using the substrate 1-chloro-2,4-dinitrobenzene (CDNB), which is the usual substrate for assaying a known general activity of GST. Since the most reactive substrate is required to reveal specific changes in enzyme activity, we also used two alternative substrates, 1,2-dichloro-4-nitrobenzene (DCNB) and ethacrynic acid (ETHA). Activities with CDNB or ETHA did not change. However, assays with DCNB showed that methyl parathion caused a decrease in GST activity in the liver on the 24th, 48th and 96th hour after the injection. DCNB also revealed that GST activity in the liver increased seven days after benzo[a]pyrene injection, coming down to normal after fourteen days. Benzo[a]pyrene, but not methyl parathion, increased the activities with DCNB in cytosol from the kidney seven and fourteen days after the injection. Thus, a decreased liver GST activity assayed with DCNB corresponded to contamination of P. mesopotamicus with methyl parathion. The increase of this GST activity in the liver and the kidney correlates to pacu contamination with polycyclic aromatic hydrocarbons.

Abstract Variations in dissolved oxygen levels are common in the Amazonian aquatic environments and the aquatic organisms that inhabit these environments developed a variety of adaptive responses to deal with such conditions. Some Amazonian fish species are tolerant to low oxygen levels and the cichlid Astronotus ocellatus is one of the most hypoxia-tolerant species. Herein, we aimed to unveil the biochemical and molecular responses that A. ocellatus presents when submitted to hypoxia. Hypoxia indicators were measured, such as plasma glucose, plasma lactate, hepatic glycogen and relative transcript levels of prolyl hydroxylase 2 (phd2) and hypoxia-inducible factor-1α (hif-1α) in juveniles of approximately 50 g exposed to 1, 3, and 5 hours of hypoxia (0.7 mg O2.L-1), followed by 3 hours of recovery in normoxia (6 mg O2.L-1). Fish exposed to hypoxia reduced liver glycogen levels within 3 hours of hypoxia, when comparing with 1 hour, and increased plasma glucose and lactate. Under the same condition, phd2 transcripts levels increased in gills, but decreased in liver. In contrast, hypoxia did not affect relative gene expression of hif-1α in both tissues. Based on the transcription pattern of phd2, these results showed that liver and gills of A. ocellatus have different molecular strategies to cope with environmental hypoxia.

OBJECTIVE: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), and Pediatric Outcome Data Collection Instrument (PODCI). RESULTS: The median current age [14 (10-18) vs. 15 (10-18) years, p=0.847] and frequency of female sex (62% vs. 58%, p=0.571) were similar in adolescents with chronic conditions compared with healthy adolescents. The frequency of poor sleep quality was similar in both groups (38% vs. 48%, p=0.118). Logistic regression analysis, including both healthy adolescents and adolescents with chronic conditions (n=387), demonstrated that self-reported increase in screen time (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.3-6.8; p=0.008) and intrafamilial violence report (OR 2.1; 95% CI 1.2-3.5; p=0.008) were independently associated with poor sleep quality in these adolescents. However, the PODCI global function score was associated with a lower OR for poor sleep quality (OR 0.97; 95% CI 0.94-0.99; p=0.001). Further logistic regression, including only adolescents with chronic conditions (n=305), demonstrated that self-reported increase in screen time (OR 3.1; 95% CI 1.4-6.8; p=0.006) and intrafamilial violence report (OR 2.0; 95% CI 1.2-3.4; p=0.011) remained independently associated with poor quality of sleep, whereas a lower PODCI global function score was associated with a lower OR for sleep quality (OR 0.96; 95% CI 0.94-0.98; p<0.001). CONCLUSION: Self-reported increases in screen time and intrafamilial violence report impacted sleep quality in both healthy adolescents and those with chronic conditions. Decreased health-related quality of life was observed in adolescents with poor sleep quality.

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

Synthetic conditions were evaluated to intercalate norbixin into layered double hydroxides (LDH). Norbixin was isolated from a hydrosoluble commercial annatto extract. LDH samples comprising M2+/Al3+ (M = Mg, Zn) were synthesized by coprecipitation and characterized by X-ray diffraction, thermal analysis coupled to mass spectrometry, vibrational spectroscopies, and solid-state 13C nuclear magnetic resonance. Radical scavenging activity of LDH hybrids was monitored by electron paramagnetic resonance towards the stable radical DPPH (1,1-diphenyl-2-picrylhydrazyl). LDH hosts presented more than 50 wt.% of norbixin and d-spacing (003) values of about 2.5 or 3.0 nm depending of the cation LDH composition. Vibrational spectra assignment (supported by density functional theory calculations) confirmed the chemical integrity of norbixin after intercalation into LDH. The inorganic layers were found to enhance the thermal stability of norbixin upon intercalation. The free radical scavenging capacity of norbixin was retained when immobilized into LDH. Considering that zinc and magnesium-LDH matrices are biocompatible and that norbixin presents biological activity, the hybrid materials appear as promising systems for biomedical assessment.
