Resumen: En el ámbito del contrato de compraventa, y específicamente en el contenido de la obligación del vendedor, el enunciado “dar una cosa” (art. 1661 del Código Civil de Uruguay) podría implicar la obligación de entregar la posesión de un bien o la obligación de transferir el dominio, aspecto que ha sido debatido en el ámbito doctrinal. A pesar de que la jurisprudencia y doctrina tradicional limitan el contenido de la obligación del vendedor al deber de entregar la posesión del bien, una revisión conceptual y contextual vinculada con otros contratos nominados del mismo Código Civil, así como con negocios jurídicos de similar contenido que la compraventa creados por leyes especiales posteriores, sumada a la aplicación de reglas de la interpretación lógico sistemática, teleológica y evolutiva, determinan que el vendedor no solo está obligado a entregar la posesión del bien objeto de la compraventa, sino también a transmitir la propiedad.

Abstract: In the context of a purchase and sale contract, specifically concerning the seller's obligations, the phrase "to give a thing" (Article 1661 of the Civil Code of Uruguay) could imply either the obligation to deliver possession of a good or the obligation to transfer ownership. This has been a subject of debate in doctrinal discussions. Although traditional jurisprudence and doctrine have limited the seller's obligation to delivering possession of the good, a conceptual and contextual review-linked with other named contracts in the same Civil Code and with similar legal transactions created by later special laws, combined with the application of logical-systematic, teleological, and evolutionary interpretation rules-determines that the seller is not only obligated to deliver possession of the good being sold but also to transfer ownership.

Resumo: No âmbito do contrato de compra e venda, e especificamente no conteúdo da obrigação do vendedor, a afirmação “dar una cosa” (dar algo; art. 1661 do Código Civil Uruguaio) poderia implicar a obrigação de entregar a posse de um bem ou a obrigação de transferir a propriedade, aspecto que tem sido debatido no campo doutrinário. Embora a jurisprudência e a doutrina tradicional limitem o conteúdo da obrigação do vendedor ao dever de entregar a posse do bem, uma revisão conceitual e contextual vinculada a outros contratos disciplinados no mesmo Código Civil, bem como a negócios jurídicos de conteúdo semelhante à compra e venda criados por leis especiais posteriores, somada à aplicação de regras de interpretação lógica sistemática, teleológica e evolutiva, determinam que o vendedor não só é obrigado a entregar a posse do bem objeto da venda, mas também a transferir a propriedade.

Abstract Objective: To assess factors associated with emotional changes and Hyperactivity/Inattention (HI) motivated by COVID-19 quarantine in adolescents with immunocompromising diseases. Methods: A cross-sectional study included 343 adolescents with immunocompromising diseases and 108 healthy adolescents. Online questionnaires were answered including socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and validated surveys: Strengths and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). Results: The frequencies of abnormal emotional SDQ scores from adolescents with chronic diseases were similar to those of healthy subjects (110/343 [32%] vs. 38/108 [35%], p = 0.548), as well as abnormal hyperactivity/inattention SDQ scores (79/343 [23%] vs. 29/108 [27%], p = 0.417). Logistic regression analysis of independent variables associated with abnormal emotional scores from adolescents with chronic diseases showed: female sex (Odds Ratio [OR = 3.76]; 95% Confidence Interval (95% CI) 2.00–7.05; p < 0.001), poor sleep quality (OR = 2.05; 95% CI 1.08–3.88; p = 0.028) and intrafamilial violence during pandemic (OR = 2.17; 95% CI 1.12–4.19; p = 0.021) as independently associated with abnormal emotional scores, whereas total PedsQL score was inversely associated with abnormal emotional scores (OR = 0.95; 95% CI 0.93–0.96; p < 0.0001). Logistic regression analysis associated with abnormal HI scores from patients evidenced that total PedsQL score (OR = 0.97; 95% CI 0.95–0.99; p = 0.010], changes in medical appointments during the pandemic (OR = 0.39; 95% CI 0.19–0.79; p = 0.021), and reliable COVID-19 information (OR = 0.35; 95% CI 0.16–0.77; p = 0.026) remained inversely associated with abnormal HI scores. Conclusion: The present study showed emotional and HI disturbances in adolescents with chronic immunosuppressive diseases during the COVID-19 pandemic. It reinforces the need to promptly implement a longitudinal program to protect the mental health of adolescents with and without chronic illnesses during future pandemics.

Abstract Cnesterodon hypselurus is a small fish that has a restricted distribution in southern Brazil, including headwaters of the Tibagi and Itararé river basins (Upper Paraná River). This study reported C. hypselurus in a headwater of Cinzas River basin, where there were no previous records of this species, and employed microsatellite loci and mitochondrial haplotypes in a population genetic analysis. A total of 57 specimens was analyzed, including 30 from Cinzas River basin, 25 from Itararé River basin and two from Tibagi River basin. Results indicated low genetic diversity levels (HE = 0.334 and h = 0.246) for the sample from Cinzas River, suggesting reflections of a founder effect after the species had dispersed from one watershed to another, possibly by headwater captures. Since different populations were detected between the Cinzas and Itararé rivers (DEST = 0.248, P-value < 0.05) and other occurrence sites are still unknown in the Cinzas River basin, the data herein have great relevance and should be taken into account in future management and conservation actions, as well as in evolutionary studies of C. hypselurus.

Resumo Cnesterodon hypselurus é um pequeno peixe que possui distribuição restrita no sul do Brasil, incluindo cabeceiras das bacias dos rios Tibagi e Itararé (alto rio Paraná). Este estudo reportou C. hypselurus na cabeceira da bacia do rio das Cinzas, onde não havia registros prévios desta espécie, e empregou locos microssatélites e haplótipos mitocondriais em uma análise genética de populações. Um total de 57 espécimes foi analisado, incluindo 30 do rio das Cinzas, 25 da bacia do rio Itararé e dois da bacia do rio Tibagi. Os resultados indicaram baixos níveis de diversidade genética (HE = 0,334 e h = 0,246) para a amostra do rio das Cinzas, sugerindo reflexos de um efeito fundador após a espécie ter dispersado de uma bacia para a outra, possivelmente a partir de captura de cabeceiras. Uma vez que diferentes populações foram detectadas entre os rios das Cinzas e Itararé (DEST = 0,248, valor de P < 0,05) e que outros pontos de ocorrência ainda são desconhecidos na bacia do rio das Cinzas, os dados do presente estudo mostram grande relevância e deveriam ser considerados em futuras ações de manejo e conservação, bem como em estudos evolutivos de C. hypselurus.

Abstract Healthcare workers present an increased risk of contagion for the SARS-CoV-2 virus due to their labor exposure. Here, we describe the clinical, laboratory, and immunological characteristics of healthcare workers, before vaccine application, exposed to SARS-CoV-2-infected patients. We collected sociodemographic, clinical, and laboratory information from 50 professionals who worked during the COVID-19 pandemic at the Clinical Hospital of the Northwest in Brazil. The results showed that most workers are women, over 50 years old, and worked as nursing technicians. Approximately 56% of workers were positive for a previous infection by RT-PCR and/or anti-SARS-CoV-2-immunoglobulin tests. Increased levels of hematocrit, neutrophils, NK lymphocytes, and fibrinogen, were found in positive healthcare workers, suggesting a light inflammatory status. The immunological findings showed an increase in IL-17 production and a Th2/Th17/Th22 profile followed by high serology for anti-SARS-CoV-2 IgM and IgG. Those data reveal the importance of studies with healthcare workers to investigate if the continuous exposition to the virus may result in chronic activation of the immune system and/or pulmonary inflammation in this target group.

Resumo Barragens são umas das principais ameaças para peixes potamódromos Neotropicais, causando bloqueios de rotas migratórias e perdas de áreas de reprodução em um número crescente de sistemas de drenagem. Neste cenário, dados atuais defendem que a manutenção de tributários de fluxo livre em bacias hidrográficas fragmentadas seria uma importante estratégia na conservação de peixes migradores, tanto em situações de panmixia quanto em cenários com diferentes estoques coexistindo, tal como já relatado para Prochilodus lineatus. Este estudo analisou locos microssatélites e haplótipos mitocondriais em amostras de P. lineatus obtidas em diferentes anos ao longo da bacia do rio das Cinzas, no reservatório de Capivara (maior reservatório na calha principal do rio Paranapanema, alto rio Paraná) e no rio Tibagi, todos conectados por trechos livres, visando investigar as contribuições da bacia do rio das Cinzas na dinâmica populacional de peixes migradores na região do reservatório de Capivara. Ambos os marcadores detectaram altos níveis de diversidade genética e indicaram diferentes estoques de P. lineatus ao longo da bacia do rio das Cinzas, sugerindo alguma estruturação genética temporal, bem como a mistura destes estoques na amostra do reservatório de Capivara e de outros pontos, corroborando as relações de estoques neste reservatório e seus tributários.

Abstract Dams are one of the main threats to Neotropical potamodromous fish, causing blockages of migratory routes and loss of breeding areas in an increasing number of drainage systems. In this scenario, current data argue that the maintenance of free-flowing tributaries along fragmented watersheds would be an important strategy to the migratory fish conservation, both in panmixia situations and in scenarios with different coexisting stocks, as already reported for Prochilodus lineatus. This study analyzed microsatellite loci and mitochondrial haplotypes in samples of P. lineatus obtained in different years along the Cinzas River basin, as well as in the Capivara Reservoir (largest Reservoir in the Paranapanema main channel, upper Paraná River) and in the Tibagi River, all connected by free stretches, aiming to investigate the contributions of the Cinzas River basin to the population dynamics of migratory fish in the Capivara reservoir region. Both markers detected high genetic diversity levels and indicated different genetic stocks of P. lineatus along the Cinzas River basin, suggesting some temporal genetic structuring, as well as the mixture of these stocks in the sample from the Capivara reservoir and from other points, corroborating the relationships among stocks in this reservoir and its tributaries. systems scenario freeflowing flowing conservation P largest channel stretches region structuring points

Abstract The present study aimed was to evaluate the spatial variability of weed species by means of phytosociological parameters and their correlations with the physical-chemical soil properties, under semiarid climate conditions. Weed phytosociology and soil characterization were carried out in two areas one newly deforested area covering 8.86 ha, and one experimental agricultural area covering 24.7 ha; both in the semi-arid region of Brazil. Weed and soil were sampled by following georeferenced grids in each area. Biomass and the total number of weed individuals, as well as soil properties, were mapped by the ordinary Kriging method. The predominant herbaceous plants in the newly deforested area were Hexasepalum teres and Digitaria insularis. The weed species that predominated in the agricultural area were Cyperus rotundus L., Euphorbia heterophylla L. and Herissantia Crispa (L.) Brizicky; the latter species outstanding for dry biomass (873.5g). Spatial dependence was observed for the predominant species, except for Digitaria insularis. The spatial distribution of these weeds was conditioned by soil K+ contents in both areas, and by sand content for the experimental agricultural area. Therefore, these two soil attributes resulted key factors for weed infestation in this semi-arid region.

Abstract A worldwide revision of the Cretaceous record of Neornithes (crown birds) revealed that unambiguous neornithine taxa are extremely scarce, with only a few showing diagnostic features to be confidently assigned to that group. Here we report two new neornithine specimens from Vega Island (López de Bertodano Formation). The first is a synsacrum (MN 7832-V) that shows a complex pattern of transversal diverticula intercepting the canalis synsacri, as in extant neornithines. Micro-CT scanning revealed a camerate pattern of trabeculae typical of neornithines. It further shows the oldest occurrence of lumbosacral canals in Neornithes, which are related to a balance sensing system acting in the control of walking and perching. The second specimen (MN 7833-V) is a distal portion of a tarsometatarsus sharing with Vegavis iaai a straight apical border of the crista plantaris lateralis. Osteohistologically the tarsometatarsus shows a thick and highly vascularized cortex that lacks any growth marks, resembling Polarornis gregorii. The cortex is osteosclerotic as in other extinct and extant diving neornithines. These new specimens increase the occurrences of the Cretaceous avian material recovered from the Upper Cretaceous strata of the James Ross Sub-Basin, suggesting that a Vegaviidae-dominated avian assemblage was present in the Antarctic Peninsula during the upper Maastrichtian.

The record of new occurrences of species is of paramount importance for the study of neotropical biodiversity, needing to be allied to a set of well-defined morphological characters. Hence, with a focus on Amazonian biodiversity, the object of our study is the genus Metaxya (Metaxyaceae). Metaxya C. Presl. has a wide distribution in Tropical America and in Brazil are recorded four of the six recognized species in the genus: M. lanosa A. R. Sm. & Tuomisto, M. rostrata (Kunth) C.Presl, M. scalaris Tuomisto & G.G.Cárdenas and M. parkeri (Hook. & Grev.) J. Sm. Thus, our aim was to revisit and look for diagnostic morphological traits for each species, adding one more point of view of species recognition, therefore, contribute to the understanding of the geographic distribution of this group. To achieve these aims, around 1,450 Metaxya samples deposited in the herbaria of national and foreign institutions were analyzed. This work presents brief morphological descriptions of species occurring in the Brazilian Amazon, comments on the morphological differences between species and their phylogenetic relationships. Additionally, we provide an identification key, new occurrences of M. rostrata for the States of Rondônia and Roraima, also M. scalaris for the Antilles and the first citation of M. parkeri for the Cerrado biome. Finally, we indicate here an isolectotype of M. parkeri in the collection of the Kew Botanical Garden (K).

O registro de novas ocorrências de espécies é de suma importância para o estudo da biodiversidade neotropical, precisando estar aliado a um conjunto de caracteres morfológicos bem definidos. Nesse sentido, com foco na biodiversidade Amazônica, o objeto do nosso estudo é o gênero Metaxya C. Presl. (Metaxyaceae). Este gênero apresenta uma ampla distribuição na América Tropical e no Brasil há relato de ocorrência de quatro das seis espécies atualmente reconhecidas no gênero: M. lanosa A. R. Sm. & Tuomisto, M. rostrata (Kunth) C.Presl, M. scalaris Tuomisto & G.G.Cárdenas e M. parkeri (Hook. & Grev.) J. Sm.. Assim, nosso objetivo foi revisitar e buscar características morfológicas diagnósticas de cada espécie que sejam mais intuitivas e que adicione mais um ponto de vista acerca do reconhecimento das espécies, e assim contribuir no entendimento da distribuição geográfica desse grupo. Para isso, foram analisadas cerca de 1.450 exsicatas de Metaxya depositadas nos herbários de instituições nacionais e do exterior. Neste trabalho são apresentadas breves descrições morfológicas das espécies ocorrentes na Amazônia brasileira, comentários sobre as diferenças morfológicas entre as espécies e suas relações filogenéticas. Adicionalmente, apresentamos uma chave de identificação, além de novas ocorrências de M. rostrata para os Estados de Rondônia e Roraima, de M. scalaris para as Antilhas e a primeira citação de M. parkeri para o bioma Cerrado. Também é indicado aqui um isolectotipo de M. parkeri na coleção do Jardim Botânico do Kew (K).

Although parabens have been reported to be used as antimicrobial preservatives in personal care products, pharmaceuticals, and foodstuffs, little is known about the occurrence of these compounds in sports supplements. In this study, a simple, fast and sensitive liquid chromatography tandem mass spectrometry method for simultaneous determination of five commonly used parabens, methyl-, ethyl-, propyl-, butyl-, and benzylparaben in sports supplements was established. The analytical method was validated with the values of parameters being acceptable. The method proved reliable, accurate, and sensitive and was successfully applied for the quantitation of parabens in 85 sports supplements samples. Almost all sports supplements contained at least one of the parabens analyzed, and the total concentrations of five parabens ranged from below the limit of quantification to 145 μg g-1, with a median value of 0.171 μg g-1. Ethylparaben and methylparaben were the most frequent paraben analogs found in samples (detection rate > 60%). Propylparaben, butylparaben and benzylparaben are forbidden in food samples, their detection rates were 49.4, 21.2 and 4.7%, respectively. Therefore, our study suggests that Brazilian population may be exposed to estrogenic not allowed parabens and their harmful effects through the intake of sports food supplements.

Abstract Background: The observation that 2-deoxy-2[18F]fluoro-D-glucose-positron emission tomography/magnetic resonance imaging ([18F]F-FDG-PET/MRI) revealed high-grade arterial wall FDG uptake, without arterial wall thickening with contrast-enhancement, in a considerable number of c-TA patients in our previous study, encouraged us to compare patients with both PET and MR angiography (MRA) positives, with those with PET positive but MRA negative. Our aim was to evaluate the relevance of these two imaging modalities together. Methods: A three-center cross-sectional study with 17 patients who fulfilled the EULAR/PRINTO/PReS criteria for c-TA and who underwent [18F]F-FDG-PET/MRI was previously performed. Herein we compared patients/vessels with positive PET (arterial wall 18F-FDG uptake higher than liver) and positive MRA (arterial wall thickening with contrast-enhancement)—group 1, with those with positive PET but negative MRA—group 2. Results: Median disease duration of 17 c-TA patients was 10.4 years. Nine patients were classified as group 1 and six as group 2. Median of metabolic inflammatory volume (MIV) of all arterial segments was significantly higher in group 1 (2346 vs. 1177 cm3; p = 0.036). Fifty-four (19%) from 284 available arterial segments presented positive findings in vessel wall in one or both images. Positive findings were concordant between PET and MRA in only 13% arterial segments (group 1); most changes (28–59.6%) that were discordant between both images, were positive in PET and negative in MRA (group 2). Conclusions: Our study demonstrated that [18F]F-FDG-PET/MRI added information about inflammation in vessel wall of c-TA patients. Prospective multicenter studies are needed in order to get solid data to guide immunosuppressive tapering and withdrawal.

Abstract Health professionals working to mitigate the COVID-19 pandemic are one of the main risk groups for the disease, being prioritized for vaccination. Considering this, the aim of this study was to analyze the immune response of these professionals immunized with CoronaVac in the first and second doses. Blood samples were collected after the first and second doses of the vaccine (CoronaVac) and used to investigate hematological and biochemical parameters, analysis of immunoglobulin production, cytokines, and gene expression profile, as well as the identification of subsets of immune cells. Post-first dose immunological phenotypic memory (CD27+) profiles (T CD4+, TCD8+ and CD19+) showed a significant increase, as did Monocyte APCs (CD80+HLA-DR+) in relation to the second dose. The cytokines IL-2, IL-6 and IFN-° showed increased values in relation to the other analyzed cytokines. The Th2/Th17 profile in the second dose was characterized by gene expression analysis. The production of IgM and IgG after vaccination showed statistically significant values in the comparison between doses. CoronaVac showed activation of APCs monocytes, memory response of T and B lymphocytes, with immunoglobulins production. This set of responses is characterized by the Th2/Th17 immunological profile.

Abstract: Background: Amaranthus hybridus L. (Amaranthaceae) is an annual, dicotyledonous species that is considered one of the main weed infesting agricultural production systems. Some weeds species are considered host plants to insect pests, serving as “green bridges” for subsequent attacks on the main crop during the season, which can cause significant losses. Recording the occurrence of insects that can reach pest status is important for the deployment of mitigation measures against possible damage and economic losses to crops. The presence of Spodoptera eridania (Cramer) (Lepidoptera: Noctuidae) has not been previously registered in association with A. hybridus plants. Objective: Thus, the present study is the first report to describe the occurrence of S. eridania on A. hybridus in the municipality of Piracicaba, São Paulo, Brazil. Methods: Images of the larvae while feeding on A. hybrids were obtained using an Olympus® E-410 digital camera. The pictures were then sent to the Laboratory of Ecotoxicology and IPM (LEMIP) of the Department of Entomology of Lavras Federal University (UFLA) for species identification. Results: We observed S. eridania larvae larger than 7 cm feeding on the inflorescences and leaves of A. hybridus . Conclusions: This note reports the first occurrence of S. eridania larvae feeding on A. hybridus in the city of Piracicaba, SP, Brazil.

RESUMO O registro de novas ocorrências de espécies é de suma importância para o estudo da biodiversidade neotropical, precisando estar aliado a um conjunto de caracteres morfológicos bem definidos. Nesse sentido, com foco na biodiversidade Amazônica, o objeto do nosso estudo é o gênero Metaxya C. Presl. (Metaxyaceae). Este gênero apresenta uma ampla distribuição na América Tropical e no Brasil há relato de ocorrência de quatro das seis espécies atualmente reconhecidas no gênero: M. lanosa A. R. Sm. & Tuomisto, M. rostrata (Kunth) C.Presl, M. scalaris Tuomisto & G.G.Cárdenas e M. parkeri (Hook. & Grev.) J. Sm.. Assim, nosso objetivo foi revisitar e buscar características morfológicas diagnósticas de cada espécie que sejam mais intuitivas e que adicione mais um ponto de vista acerca do reconhecimento das espécies, e assim contribuir no entendimento da distribuição geográfica desse grupo. Para isso, foram analisadas cerca de 1.450 exsicatas de Metaxya depositadas nos herbários de instituições nacionais e do exterior. Neste trabalho são apresentadas breves descrições morfológicas das espécies ocorrentes na Amazônia brasileira, comentários sobre as diferenças morfológicas entre as espécies e suas relações filogenéticas. Adicionalmente, apresentamos uma chave de identificação, além de novas ocorrências de M. rostrata para os Estados de Rondônia e Roraima, de M. scalaris para as Antilhas e a primeira citação de M. parkeri para o bioma Cerrado. Também é indicado aqui um isolectotipo de M. parkeri na coleção do Jardim Botânico do Kew (K).

ABSTRACT The record of new occurrences of species is of paramount importance for the study of neotropical biodiversity, needing to be allied to a set of well-defined morphological characters. Hence, with a focus on Amazonian biodiversity, the object of our study is the genus Metaxya (Metaxyaceae). Metaxya C. Presl. has a wide distribution in Tropical America and in Brazil are recorded four of the six recognized species in the genus: M. lanosa A. R. Sm. & Tuomisto, M. rostrata (Kunth) C.Presl, M. scalaris Tuomisto & G.G.Cárdenas and M. parkeri (Hook. & Grev.) J. Sm. Thus, our aim was to revisit and look for diagnostic morphological traits for each species, adding one more point of view of species recognition, therefore, contribute to the understanding of the geographic distribution of this group. To achieve these aims, around 1,450 Metaxya samples deposited in the herbaria of national and foreign institutions were analyzed. This work presents brief morphological descriptions of species occurring in the Brazilian Amazon, comments on the morphological differences between species and their phylogenetic relationships. Additionally, we provide an identification key, new occurrences of M. rostrata for the States of Rondônia and Roraima, also M. scalaris for the Antilles and the first citation of M. parkeri for the Cerrado biome. Finally, we indicate here an isolectotype of M. parkeri in the collection of the Kew Botanical Garden (K).
