ABSTRACT The presence of salts in the culture medium and the addition of phytohormones, necessary to break seed dormancy in the in vitro germination of passion fruit, can induce critical values of osmotic potential. This can change the membrane permeability of seeds, affecting the hydration rate, enzyme release, ion transport, pH, and inhibitor values, which may decrease germination percentage. The aim of this study was to evaluate different types of culture media, composed of other substances, combined with mechanical techniques of tegument removal to determine the most appropriate culture medium for the in vitro germination of Passiflora edulis (Sims flavicarpa Deg.) seeds obtained by open pollination. The experimental design was completely randomized in a 10 × 3 factorial scheme (10 culture media × three types of seed-intact, scarified, and cut), with eight replicates and five seeds per plot. Scarified seeds cultivated in a medium composed of a commercial substrate and gibberellic acid presented a higher percentage of germination than intact or cut seeds cultivated in different concentrations of Murashige & Skoog (MS) medium. Scarification is a satisfactory method for breaking the dormancy of passion fruit seeds, and commercial substrates Bioflora® enriched with gibberellic acid may replace in vitro germination.
RESUMO A presença de sais no meio de cultura e a adição de fitohormônios, necessários para quebrar a dormência das sementes na germinação in vitro do maracujá, podem levar o potencial osmótico a níveis críticos. Isso pode alterar a permeabilidade da membrana das sementes, afetando a taxa de hidratação, a liberação de enzimas, o transporte iônico, o pH e os teores de inibidores, o que pode acarretar na diminuição do percentual de germinação. O objetivo desta pesquisa foi avaliar diversos tipos de meios de cultura, compostos por diferentes substâncias, combinados com técnicas mecânicas de remoção do tegumento, para determinar o tratamento mais adequado para a germinação in vitro de sementes de Passiflora edulis (Sims flavicarpa Deg.) obtidas por polinização aberta. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 10 × 3 (10 meios de cultura × três tipos de sementes - intactas, escarificadas e cortadas), com oito repetições e cinco sementes por parcela. Sementes escarificadas cultivadas em meio composto de substrato comercial e ácido giberélico apresentaram taxa de germinação superior às sementes intactas ou cortadas cultivadas em diferentes concentrações de meio Murashige & Skoog (MS). A escarificação é um método satisfatório de quebra de dormência de sementes de maracujá e substratos comerciais Bioflora® enriquecidos com ácido giberélico podem substituir o meio MS na germinação in vitro.

ABSTRACT: This study discusses the epidemiological, clinical, and pathological characteristics of two outbreaks of ocular infection in ostriches (Struthio camelus) caused by the trematode Philophthalmus sp. The outbreaks occurred in the states of Ceará and Rio Grande do Norte in Northeast Brazil. Ostrich farming was categorized as semi-intensive farming with free access to the weir and river. The clinical symptoms for infection included nictitating membrane inflammation, epiphora (tearing), eyelid edema, ocular congestion, eyeball destruction, emaciation, and death, and the infection period ranged from 8 to 16 months. Macroscopically, thickening of the eyelids and conjunctiva were observed, with orange parasites infestation. Histologically, the lesions were characterized as lymphoplasmacytic and heterophilic, multifocal to coalescing, moderate, chronic conjunctivitis associated with hyperplasia and ectasia of the Harderian gland, and numerous parasites. The parasites were oval and flattened with an oral suction cup, acetabulum, and thick cuticle containing spicules. The diagnosis of philophthalmiasis was based on epidemiological, clinical, and pathological findings associated with the morphological characteristics of the parasites present in the conjunctival sacs which were similar to the trematode Philophthalmus sp. Philophthalmiasis can occur in ostriches raised on urban and rural properties in Northeastern Brazil, probably associated with the contact of birds with contaminated water, and is characterized by severe conjunctivitis that can result in the loss of the eyeball and death of the animals.
RESUMO: Descrevem-se as características epidemiológicas, clínicas e patológicas de dois surtos de infecção ocular pelo trematódeo Philophthalmus sp. em avestruzes ocorridos nos estados do Ceará e Rio Grande do Norte no Nordeste do Brasil. As propriedades tinham em comum, a criação semi-intensiva e livre acesso a açude e rio. Os sinais clínicos incluíam protrusão da membrana nictante, lacrimejamento, edema palpebral, congestão ocular, destruição do globo ocular, emagrecimento e morte. A evolução clínica variou de oito a 16 meses. Macroscopicamente, observou-se espessamento das pálpebras e conjuntivas associado a numerosas estruturas parasitárias alaranjadas. No segundo surto, as lesões eram mais graves e consistiam em perda do globo ocular direito e anexos. Histologicamente, as lesões caracterizavam-se por conjuntivite linfoplasmocítica e heterofílica, multifocal a coalescente, moderada, crônica associada a hiperplasia e ectasia da glândula de Harderian e numerosas estruturas parasitárias. Os parasitas eram ovalados, achatados com ventosa oral e acetábulo e cutícula espessa contendo espículas. O diagnóstico de filoftalmíase foi realizado com base nos achados epidemiológicos, clínicos e patológicos associadas as características morfológicas dos parasitas presentes nos sacos conjuntivais compatíveis com o trematódeo Philophthalmus sp. A filoftalmíase pode ocorrer em avestruzes criados em propriedades urbanas e rurais no Nordeste do Brasil, provavelmente associado ao contato das aves com água contaminada e caracteriza-se por quadros de conjuntivite grave que pode resultar com a perda do globo ocular e morte dos animais.

Abstract The work aims to show contextual factors, from the Institutional Collective Action (ICA), that influence the inter-municipal cooperation of waste treatment inter-municipal public consortia in the Metropolitan Regions in Brazil. Inter-municipal Consortia in the solid waste area are important for the National Solid Waste Policy (law 12,305/2010). With the inter-municipal aggregation it is possible to build sanitary landfills, something that requires scale, and there, the metropolitan regions, in theory, are potential agglomerations for this type of policy. For the development of the study, Factor Analysis and Multivariate Data Analysis were used, based on Multidimensional Scaling. The study concludes that the influencing factors in the creation of consortia in metropolitan regions are: Characteristics of transaction goods, Characteristics of Communities, Political Institutions and Structure of Political Relations.
Resumo O trabalho tem o objetivo de mostrar fatores contextuais, a partir da Instititutional Collective Action (ICA), que influenciam a cooperação intermunicipal dos consórcios públicos intremunicipais de tratamento de resíduos nas Regiões Metropolitanas no Brasil. Os consórcios públicos intermunicipais na área de resíduos sólidos são importantes para a Política Nacional de Resíduos Sólidos (lei 12.305/2010). Com a agregação intermunicipal é possível a construção de aterros sanitários, algo que requer escala, e aí, as regiões metropolitanas, em tese, são aglomerações potenciais para este tipo de política. Para desenvolvimento do estudo foi utilizada a Análise Fatorial, e a Análise de Dados Multivariados, a partir do Escalonamento Multidimensional. O estudo conclui que os fatores influenciadores na criação de consórcios em regiões metropolitanas são: Características dos bens de transação, Características das Comunidades, Instituições Políticas e Estrutura das Relações Políticas.

The aim of the current study was the valorization of hesperidin, the dominant flavonoid in citrus processing waste, by microwave-assisted synthesis of hesperidin-Mg complex, improving its antioxidant activity and insecticidal potential. Here we show, for the first time, that microwave-assisted synthesis of [Mg(hesp)2(phen)]OAc (1) (hesp: hesperidin, phen: phenanthroline) improve the reaction rate and yield. The nuclear magnetic resonance (NMR) experiments proved to be powerful tools for the identification of three isomers in metal complexes. Moreover, we explore the insecticidal potential of 1 and [Mg(phen)2(Isov)]OAc (2) (Isov : isovanillic acid) complexes against three insects. Complex 1 killed 80% of adults whitefly at 0.14 μmol L-1, and 2 76% at 0.36 μmol L-1. There was a total mortality of Spodoptera frugiperda with 2 at 0.39 μmol L-1, and 83% with 1 at 0.14 μmol L-1. Both have similar activity, and represent a novel group of insecticide for Bemisia tabaci and S. frugiperda; nevertheless, the benefits of both as Myzus persicae repellent require further evaluation.

This study searched for a new pre-formulation based on the natural compound from the class of the avermectins, named abamectin (ABA), in order to improve its action against Aedes aegypti larvae by complexation with β-cyclodextrin (βCD). Concerning the low aqueous solubility of ABA, even in the presence of βCD, it was also invoked the strategy of working with hydrophobic nanoprecipitates (HNPs). For these purposes, molecular and supramolecular characterizations of 1:1 ABA/βCD complex and evaluation of its toxicity against A. aegypti larvae were performed. In the physical-chemistry characterizations, changes in the infrared spectra and thermal profiles in relation to precursors confirmed the occurrence of interactions between ABA and βCD in solid state. Nuclear magnetic resonance (NMR) data suggest the inclusion of ABA in βCD via benzofuran ring. Isothermal titration calorimetry (ITC) experiments allowed to verify the formation of complex with a 1:1 stoichiometry, which was entropy driven. The dynamic light scattering and zeta potential data from inclusion compounds demonstrated changes in the size of the ABA/βCD HNP if compared with the ABA HNP. Finally, the results for biological assays demonstrate that the strategy to prepare the inclusion compound led to an increase in the larvicidal activity in relation to free ABA.

Nowadays, microwave-assisted procedures using closed vessels with thermal, chemical, and mechanical resistance are the state-of-the-art for efficient digestion of samples. Safety issues related to sample reactivity should be considered and analytical throughput is also a critical parameter. The choice of a specific vessel for a target application is not trivial and simple experiments are presented here for rice flour and bovine liver samples to illustrate effects of vessel design on digestion performance. Despite using the same heating program, the residual carbon contents varied from 22 to 67% to bovine liver digests and from 7 to 96% to rice flour digests. Quantitative recoveries were obtained for most analytes. Low recoveries were observed mainly for Ca and Fe. Analytical performance is related to different sizes, shapes and the gradient of temperature for each model of digestion vessel. It was demonstrated that taller vessels improved regeneration of nitric acid.

RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.
Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.

Croton grewioides Baill. popularly known as “canelinha” or “canelinha-de-cheiro” has been used for the treatment of influenza, antitussive, febrifuge and headache; however, the study of its phytochemical composition is limited. The aim of this study was to investigate the effect of the extraction method and seasonality through leaf extracts of four accessions of Croton grewioides by fingerprint chromatograms aided by principal component analysis to analyze the differences and similarities among the samples. We aimed also to provide chemical characterization of isolated secondary metabolites using semi-preparative liquid chromatography. The results showed that only the chemical profile of the methanolic extracts of accessions 101 and 113 were influenced by the seasonality. For the first time, four flavonoids were isolated through semi-preparative chromatography in this species, characterized as quercetin 3-O-β-D-galactopyranosyl-(1→2)-α-L-rhamnopyranoside-(1→6)-α-L-rhamnopyranoside (1), quercetin 3-O-β-D-galactopyranosyl-(1→2)-α-apiopyranoside-(1→6)-α-L-rhamnopyranoside (2), quercetin 3-O-glucopyranoside (3) and 3-O-methyl-quercetin (4), the flavonoid (2) has been recognized as a new triglycosylated derivative.

Abstract The objective of this study was to evaluate high-concentrate diets and two energy sources on intake, performance and meat quality parameters of feedlot Nellore heifers. Twenty-eight heifers (200 ± 22.5 kg BW) were randomly assigned to four treatments in a 2×2 factorial arrangement: two concentrate levels (70 and 80%) and two energy sources (corn and corn germ meal). At the end of day 112, heifers were slaughtered. There was no interaction (P>0.05) of concentrate levels and energy sources for dry matter intake, unlike crude protein (CP) and neutral detergent fiber (NDF) intakes. The concentrate level of 80% and corn, allowed the highest CP (1.17 kg/day) and NDF (4.05 kg/day) intakes. Final BW (P<0.05) and daily gain (P<0.01) were influenced just by energy source. The carcass composition represented by muscle and fat was affected by concentrate level (P<0.05). Treatments affected (P<0.01) carcass fat deposition, global preference and texture of Longissimus muscle (P<0.05). It was concluded that high proportions of concentrate containing corn as energy source provided the best performance in heifers, and that the total replacement of corn with corn germ meal in high-concentrate diets is not recommended for performance Nellore heifers, but provided good sensory quality to the meat.

Resumo Os recifes de coral abrigam uma das maiores biodiversidades de peixes do planeta; no entanto, as informações sobre peixes de recife ainda estão ausentes em muitas regiões. Analisamos a riqueza, distribuição e a conservação de peixes recifais na maior Área de Proteção Ambiental (APA) costeira de uso múltiplo do Brasil; área que possui grande extensão de recifes de corais no SWA. Um total de 325 espécies de peixes foram listadas para APA Costa dos Corais, incluindo Chondrichthyes (28 espécies) e Actinopterygii (297). As espécies de peixes foram representadas por 81 famílias e as famílias mais representativas foram Carangidae (23 espécies), Labridae (21) e Gobiidae (15). A riqueza de peixes da APA representou 44% de todas as espécies de peixes registradas no Oceano Atlântico Sudoeste (SWA), destacando a importância em grande escala desta APA. Um total de 40 espécies (12%) estão registradas como Quase Ameaçada (NT), Vulnerável (VU), Em Perigo (EN) ou Criticamente Em Perigo (CR). Este estudo reforça a importância da APA Costa dos Corais na biodiversidade e conservação dos peixes recifais e enfatiza a necessidade urgente de estratégias de conservação.
Abstract Coral reefs harbor one of the largest fish biodiversity on earth; yet information on reef fishes is still absent for many regions. We analyzed reef fish richness, distribution, and conservation on the largest Brazilian multiple use coastal MPA; which cover a large extent of coral reefs at the SWA. A total of 325 fish species have been listed for MPA Costa dos Corais, including Chondrichthyes (28 species) and Actinopterygii (297). Fish species were represented by 81 families and the most representative families were Carangidae (23 species), Labridae (21) and Gobiidae (15). The MPA fish richness represented 44% of all recorded fish species of the Southwestern Atlantic Ocean (SWA) highlighting the large-scale importance of this MPA. A total of 40 species (12%) are registered at Near Threatened (NT), Vulnerable (VU), Endangered (EN) or Critically Endangered (CR). This study reinforces the importance of MPA Costa dos Corais on reef fish biodiversity and conservation and emphasize the urgent need of conservation strategies.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) is associated with high mortality among hospitalized patients and incurs high costs. Severe acute respiratory syndrome coronavirus 2 infection can trigger both inflammatory and thrombotic processes, and these complications can lead to a poorer prognosis. This study aimed to evaluate the association and temporal trends of D-dimer and C-reactive protein (CRP) levels with the incidence of venous thromboembolism (VTE), hospital mortality, and costs among inpatients with COVID-19. METHODS: Data were extracted from electronic patient records and laboratory databases. Crude and adjusted associations for age, sex, number of comorbidities, Sequential Organ Failure Assessment score at admission, and D-dimer or CRP logistic regression models were used to evaluate associations. RESULTS: Between March and June 2020, COVID-19 was documented in 3,254 inpatients. The D-dimer level ≥4,000 ng/mL fibrinogen equivalent unit (FEU) mortality odds ratio (OR) was 4.48 (adjusted OR: 1.97). The CRP level ≥220 mg/dL OR for death was 7.73 (adjusted OR: 3.93). The D-dimer level ≥4,000 ng/mL FEU VTE OR was 3.96 (adjusted OR: 3.26). The CRP level ≥220 mg/dL OR for VTE was 2.71 (adjusted OR: 1.92). All these analyses were statistically significant (p<0.001). Stratified hospital costs demonstrated a dose-response pattern. Adjusted D-dimer and CRP levels were associated with higher mortality and doubled hospital costs. In the first week, elevated D-dimer levels predicted VTE occurrence and systemic inflammatory harm, while CRP was a hospital mortality predictor. CONCLUSION: D-dimer and CRP levels were associated with higher hospital mortality and a higher incidence of VTE. D-dimer was more strongly associated with VTE, although its discriminative ability was poor, while CRP was a stronger predictor of hospital mortality. Their use outside the usual indications should not be modified and should be discouraged.

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.

As a cosmopolitan family, Ganodermataceae has as distinctive characteristic the presence of double-walled basidiospore: the inner wall thick and ornamented, and the outer wall smooth. Even with the increasing interest in this family, the species are still poorly known in different regions of the brazilian territory, such as in the central Brazil. This study presents new distribution remarks of Ganodermataceae species in different sites of the biome Cerrado, in the Midwest region. We found 23 specimens from five species which are distributed into three genera, Amauroderma, Foraminispora and Ganoderma. From those species, one is a new record for the Cerrado (A. exile), four are new for the State of Goiás A. exile, F. rugosa, G. multiplicatum and G. stipitatum and one for the Distrito Federal (G. stipitatum). Amauroderma aurantiacum is rediscovered in Goiás after 88 years. This study contributes to improving the knowledge regarding the geographic distribution of these taxa in Brazil.
Cosmopolita, a família Ganodermataceae tem como característica distintiva a presença de basidiósporos de parede dupla, sendo a interna espessa e ornamentada e a externa lisa. Mesmo com o crescente interesse pela família, as espécies ainda permanecem muito pouco conhecidas em diferentes localidades do território brasileiro, como é o caso do Brasil central. Este trabalho relata novas ocorrências de espécies de Ganodermataceae em diferentes localidades do bioma Cerrado, na região Centro-Oeste. Os espécimes estudados somam 23 exemplares de cinco espécies, distribuídas em três gêneros, Amauroderma, Foraminispora e Ganoderma. Dessas, uma é novo registro para o Cerrado (A. exile), quatro são novas para o estado de Goiás A. exile, F. rugosa, G. multiplicatum e G. stipitatum e uma para o Distrito Federal (G. stipitatum). Amauroderma aurantiacum é novamente registrada para o estado de Goiás após 88 anos. Este trabalho contribui para ampliar o conhecimento da distribuição geográfica das espécies no Brasil.
