RESUMO Regiões com climas semiáridos apresentam condições ambientais que resultam em estresses abióticos às plantas. A maior área de produção de melão (Cucumis melo L.) do Brasil, o Estado do Rio Grande do Norte, possui essas características climáticas. O uso de bioestimulantes nesses sistemas de produção pode mitigar os efeitos dos estresses abióticos e aumentar a produtividade e a qualidade dos frutos. O objetivo neste estudo foi avaliar as características fisiológicas e de produção do meloeiro, sob aplicação de bioestimulantes. Os bioestimulantes Acadian®, Folicist® e Nov@® foram aplicados e comparados ao tratamento controle (sem bioestimulantes), em melões ‘Goldex’ e ‘McLaren’. Nov@® proporcionou maior assimilação de CO2, transpiração e condutância estomática, assim como ascorbato peroxidase em ‘Goldex’ e ‘McLaren’. Maior catalase foi obtida pela aplicação de Nov@®, enquanto que o uso de Folicist® resultou em maior teor de malondialdeído. A cultivar McLaren apresentou o melhor desempenho fisiológico e bioquímico e a ‘Goldex’ o melhor rendimento. Folicist® promove adaptações fisiológicas aos estresses sem prejudicar a atividade fotossintética. Os bioestimulantes aumentaram a produtividade e o número de frutos por planta e promoveram adaptações fisiológicas às condições semiáridas. plantas Cucumis L.

ABSTRACT Regions with semi-arid climates have environmental conditions that result in abiotic stress to plants. The largest melon (Cucumis melo L.) production area in Brazil, the state of Rio Grande do Norte, has these climatic characteristics. Use of biostimulants in these production systems can mitigate effects of abiotic stress and increase yield and fruit quality. The objective in this study was to evaluate the physiological and production characteristics of melon, under the application of biostimulants. The biostimulants Acadian®, Folicist® and Nov@® were applied and compared to the control treatment (no biostimulants), in ‘Goldex’ and ‘McLaren’ melons. Nov@® led to higher CO2 assimilation, transpiration and stomatal conductance, as well as ascorbate peroxidase, in ‘Goldex’ and ‘McLaren’. Greater catalase was obtained with the application of Nov@®, while the use of Folicist® resulted in higher malondialdehyde content. The cultivar ‘McLaren’ exhibited the best physiological and biochemical performance, and ‘Goldex’ the best yield. Folicist® promotes physiological adaptations to stress without impairing photosynthetic activity. The biostimulants increased yield and number of fruits per plant and promoted physiological adaptations to semi-arid conditions. semiarid semi arid plants Cucumis L.

RESUMO A cultura do sorgo é considerada uma das mais importantes do mundo devido a sua versatilidade de utilização. No entanto, o estresse hídrico pode ser considerado uma ameaça significativa para sua produtividade. A busca por produtos mitigadores do estresse hídrico é uma área de pesquisa crucial na agricultura e na gestão de recursos hídricos. Assim, o objetivo deste trabalho foi avaliar a viabilidade do uso do ácido salicílico como atenuante de estresse hídrico na cultura do sorgo. O experimento foi conduzido em ambiente telado, em delineamento em blocos ao acaso com esquema fatorial 4 × 2, com quatro repetições. Foram avaliados quatro níveis hídricos (40, 60, 80 e 100% da evapotranspiração) e duas concentrações de ácido salicílico (0 e 2,76 g L-1). Foram analisados a altura das plantas, diâmetro do caule, número de folhas, trocas gasosas, pigmentos fotossintéticos e fluorescência da clorofila a. A aplicação de lâminas de irrigação deficitárias reduziu a altura da planta, diâmetro do colmo, número de folhas e clorofila total no sorgo. No entanto, quando essas lâminas foram associadas ao ácido salicílico, foi observado que houve atenuação dos danos, especialmente em relação a clorofila a e b. Além disso, o ácido salicílico quando aplicado isoladamente, contribuiu para redução da temperatura da folha e aumento da eficiência de uso da água. Assim, o ácido salicílico pode ser usado para mitigar os efeitos do estresse salino em plantas de sorgo. utilização entanto produtividade Assim telado 2 repetições 40, 40 (40 60 8 100 evapotranspiração 0 ( 276 76 2,7 L1.

ABSTRACT The sorghum crop is considered one of the most important worldwide due to its versatility. However, water stress can be considered a significant threat to its yield. The search for products that mitigate water stress is a crucial area of research in agriculture and water resources management. Thus, the objective in this study was to evaluate the feasibility of using salicylic acid as a water stress attenuator in sorghum. The experiment was conducted in a screened environment in a randomized block design with a 4 × 2 factorial scheme, with four replicates. Four levels of water (40, 60, 80, and 100% of evapotranspiration) and two concentrations of salicylic acid (0 and 2.76 g L-1) were evaluated. Plant height, stem diameter, number of leaves, gas exchange, photosynthetic pigments, and chlorophyll a fluorescence were analyzed. Application of deficit irrigation depths reduced plant height, stem diameter, number of leaves, and total chlorophyll in sorghum. However, when these depths were associated with salicylic acid, it was observed that the damage was attenuated, especially in chlorophyll a and b. Furthermore, salicylic acid reduced leaf temperature and increased water use efficiency when applied alone. Thus, salicylic acid can be used to mitigate the effects of salt stress on sorghum plants. versatility However yield management Thus scheme replicates 40, 40 (40 60 80 100 evapotranspiration 0 ( 276 76 2.7 L1 L 1 L-1 evaluated height diameter leaves exchange pigments analyzed attenuated b Furthermore alone plants (4 6 8 10 27 7 2.

RESUMO As características climáticas comuns em regiões semiáridas podem causar estresse abiótico e ser um fator limitante ao cultivo agrícola. Nessas condições, o uso de elementos benéficos como o selênio (Se) é uma alternativa para mitigar os efeitos deletérios dos estresses abióticos e aumentar a produtividade. Portanto, esta pesquisa teve como objetivo avaliar o desempenho agronômico da cebola cultivada em região semiárida sob aplicação de Se. Foi conduzido um experimento de campo, delineado em blocos casualizados completos, onde foram testadas cinco doses de Se (0, 15, 30, 45 e 60 g ha-1), por aplicação foliar, em dois híbridos de cebola (Andrômeda e Rio das Antas). Foram analisadas variáveis de crescimento, nutricional e produtividade. O Se aumentou a altura e o acúmulo de massa seca em plantas de cebola, com máxima na dose 60 g ha-1 de Se, mesma dose em que foi obtida a maior produtividade comercial (78,15 t ha-1) e total (86,03 t ha-1) de bulbos em Rio das Antas, todavia, para Andrômeda, não ocorreu efeito do Se sobre a produtividade. As doses de Se também aumentaram o teor desse elemento nos bulbos. Apesar de aumentar a produtividade de bulbos apenas em Rio das Antas, recomenda-se a aplicação de 60 g ha-1 de Se em cebola devido aos efeitos no crescimento da planta e na biofortificação dos bulbos com Se. agrícola condições (Se Portanto campo completos 0, 0 (0 15 30 4 6 ha1, ha1 ha 1 , foliar Andrômeda Antas.

ABSTRACT The common climatic characteristics in semi-arid regions can cause abiotic stress and be a limiting factor for crops. Under these conditions, the use of beneficial elements such as selenium (Se) is an alternative to mitigate the harmful effects of abiotic stresses and increase yield. Therefore, this research aimed to evaluate the agronomic performance of onion grown in a semi-arid region under the application of Se. A field experiment was performed in a randomized block design, where five doses of Se (0, 15, 30, 45, and 60 g ha-1), by foliar application, were tested on two onion hybrids (Andrômeda and Rio das Antas). Growth, nutritional and yield variables were analyzed. Se increased the height and accumulation of dry mass in onion plants, with a maximum at the 60 g ha-1 dose of Se, the same dose at which the highest commercial (78.15 t ha-1) and total (86.03 t ha-1) bulb yields were obtained in Rio das Antas; however, for Andrômeda, there was no effect of Se on yield. Applied Se doses also increased the content of this element in the bulbs. Despite increasing bulb yields only in the Rio das Antas hybrid, 60 g ha-1 of Se is recommended for onions due to its effects on plant growth and the biofortification of bulbs with Se. semiarid semi arid crops conditions (Se Therefore design 0, 0 (0 15 30 45 6 ha1, ha1 ha 1 , Andrômeda Antas. .

ABSTRACT Objective: To evaluate the surgical anatomy of the kidney collecting system through a narrative review of the literature, highlighting its importance during diagnosis and its approach during surgical procedures for the treatment of renal stones. Material and Methods: We carried out a review about the anatomy of the kidney collecting system. We analyzed papers published in the past 40 years in the databases Pubmed, Embase and Scielo, and we included only papers in English and excluded case reports, editorials and opinions of specialists. Results: Renal collecting system could be divided in four groups: A1 – kidney midzone (KM), drained by minor calyx that are dependent on the superior or the inferior caliceal groups; A2 – KM drained by crossed calyx, one draining into the superior caliceal group and another draining into the inferior caliceal group; B1 – KM drained by a major caliceal group independent of both the superior and inferior groups; and B2 – KM drained by minor calyx entering directly into the renal pelvis. Some details and anatomic variations of the collecting system are related to clinical and radiological aspects, particularly perpendicular calyces, interpyelocalyx space, position of calyces in relation to renal border, classification of the renal collecting system, infundibular diameter and the angle between the lower infundibulum and renal pelvis. Conclusion: The knowledge of intra-renal collecting system divisions and variations as the angle between the renal pelvis and lower infundibula, position of the calices in relationship with renal edge and the diameter and position of the calyces are important for the planning of minimally invasive renal surgeries.

Resumo A produção de meloeiro no semiárido brasileiro está sujeita a utilização de águas marginais com salinidade elevada. Entretanto, a utilização de reguladores e bioativadores no tratamento de sementes podem mitigar os efeitos nocivos dos sais na água de irrigação. Nesse sentido, objetivou-se avaliar o efeito de tratamentos pré-germinativos com fitorreguladores e bioativador em sementes de melão para a produção de mudas irrigadas com água biossalina de efluente de piscicultura. Para isso, dois ensaios com os híbridos Goldex e Grand Prix foram realizados separadamente. Utilizou-se delineamento inteiramente casualizado em esquema fatorial 4 × 3 (tratamentos pré-germinativos × diluições de água). Além do controle, as sementes foram tratadas com os ácidos salicílico e giberélico, e tiametoxam. As águas utilizadas para irrigação foram a de abastecimento local, efluente de piscicultura (água biossalina) e estas diluídas a 50%. Durante quatorze dias foram realizadas as análises fisiológicas e bioquímicas. A água biossalina (5,0 dS m-1) não afetou a emergência de plântulas de meloeiro Goldex, mas prejudicou o estabelecimento da cultivar Grand Prix. Os pré-tratamentos de sementes com os ácidos salicílico e giberélico atenuam os efeitos da salinidade da água e promovem modulações no crescimento, proporcionando mudas de meloeiro mais vigorosas.

Abstract Melon production in the Brazilian semi-arid region is subject to the use of marginal waters with high salinity. However, the use of regulators and bioactivators in seed treatment can mitigate the harmful effects of salts in irrigation water. In this context, the objective was to evaluate the effect of pre-germination treatments with plant regulators and bioactivator in melon seeds for the production of seedlings irrigated with biosaline water from fish farming effluent. For this, two trials with the Goldex and Grand Prix hybrids were carried out separately. A completely randomized design was used in a 4 × 3 factorial scheme (pre-germination treatments × water dilutions). In addition to the control, the seeds were treated with salicylic and gibberellic acids and thiamethoxam. The waters used for irrigation were local-supply water, fish farming effluent (biosaline water) and these diluted to 50%. Physiological and biochemical analyses were performed for fourteen days. Biosaline water (5.0 dS m-1) did not affect the emergence of Goldex melon seedlings, but compromised the establishment of the Grand Prix cultivar. Seed pre-treatments with salicylic and gibberellic acids attenuate the effects of water salinity and promote growth modulations, resulting in more vigorous melon seedlings.

Resumo Diversidade molecular, morfológica, perfil químico qualitativo e atividade antioxidante de fungos filamentosos do trato digestivo de Phylloicus sp. (Trichoptera: Calamoceratidae). Este estudo visou identificar por análises molecular, morfológica, química e por extrato antioxidante, fungos filamentosos isolados do trato digestivo de Phylloicus sp, um inseto aquático que vive entre folhagens em riachos tropicais, e participam junto com os fungos da decomposição de substratos vegetais em habitats aquáticos. Larvas de insetos de Phylloicus sp. foram coletadas em riachos no Estado do Tocantins, Brasil. Os fungos foram isolados a partir do trato digestivo das larvas após desinfecção e dissecção, depois descritos e purificados para fins de identificação e testes para atividade antioxidante. A identidade molecular foi realizada do sequenciamento ITS1 e ITS4, TUB e TEF. Os extratos fúngicos foram produzidos em solução etanólica 70% e posterior liofilização. Para análise de grupos químicos dos extratos, foi realizada cromatografia em camada delgada (CCD) em duas fases móveis e diferentes reveladores. A morfologia foi realizada por microscopia óptica corada com Azul de Toluidina e a mensuração realizada no programa ImageJ. A atividade antioxidante realizada em CCD e por método quantitativo para os radicais DPPH e peróxido de hidrogênio (H2O2). Foram identificados quatro fungos: Endomelanconiopsis endophytica, Myxospora musae, Neopestalotiopsis cubana e Fusarium pseudocircinatum. Na CCD foi evidenciado várias manchas com fase móvel acetona/clorofórmio e reveladores UV 254 nm e vapor de I2. Os extratos fúngicos demonstram ação antioxidante para redução do radical livre DPPH e em especial para H2O2 acima de 50%, E. endophytica 91.6%, M. musae 87.8%, N. cubana 89.5% e 92.3% para F. pseudocircinatum. Este estudo demonstrou que a técnica molecular por PCR foi satisfatória para identificação dos fungos, e os extratos com inúmeros grupos químicos e potentes agentes redutores. Com isso, trabalhos futuros deverão ser realizados avaliando essas quatro espécies para uso industrial.

Abstract This study aimed to identify by molecular analysis, morphology, chemistry and antioxidant extracts of filamentous fungi isolated from the digestive tract of Phylloicus sp, an aquatic insect that lives on leaf packages in tropical streams and participates together with fungi of the decomposition of plant substrates in aquatic habitats. Insect larvae of Phylloicus sp. were collected in streams in the state of Tocantins, Brazil. Fungi were isolated from the digestive tract of larvae after disinfection and dissection, then described and purified for identification purposes and testing for antioxidant activity. Molecular identity was performed of ITS1 and ITS4, TUB e TEF sequencing. Fungal extracts were produced in 70% ethanol solution and later lyophilized. For analysis of chemical groups of extracts, thin layer chromatography (TLC) was performed in two mobile phases and different developers. Morphology was performed by optical microscopy stained with Toluidine Blue and measurement performed using the ImageJ program. Antioxidant activity performed in TLC and by quantitative method for DPPH and hydrogen peroxide (H2O2) radicals. Four fungi were identified: Endomelanconiopsis endophytica, Myxospora musae, Neopestalotiopsis cubana and Fusarium pseudocircinatum. The TLC showed several spots with acetone/chloroform mobile phase and UV 254 nm developers and I2 vapor. Fungal extracts demonstrate antioxidant action to reduce the DPPH free radical and especially for H2O2 above 50%, E. endophytica 91.6%, M. musae 87.8%, N. cubana 89.5% and 92.3% for F. pseudocircinatum. This study demonstrated that the molecular technique by PCR was satisfactory for identifying fungi, and extracts with numerous chemical groups and potent reducing agents. Thus future work, should be carried out evaluating these four species for industrial use.

This work aims to optimize the process of extracting pigments from the peel of Amazonian fruits (bacupari, peach palm, and tucumã) using the enzyme pectinase. First, pigment extraction was carried out using different solvents (ethanol and acetone 80%, ethanol and acetone 50%, and water), temperatures (44, 40, 35, and 26 °C), and wavelengths (400, 450, and 490 nm). In the second stage, the best parameters found in the first stage were applied in a statistic with a response surface varying time (60, 120, and 180 min) and enzyme concentration (40, 80, and 120 U). The best results for extraction for bacupari and peach palm were acetone at 50% and 45 °C and ethanol at 50% and 35 °C for tucumã. In the second stage, the optimum point found was 1.5 h and 100 U concentration, and 2.5 h and 90 U concentration resulted in better extractions for bacupari, peach palm, and tucumã.

The increase in the number of users, hospitalizations and deaths due to overdose of synthetic opioids made the scientific community to treat this problem as “the opioid crisis”, justifying the need for the development of analytical strategies to identify and quantify these drugs. Even with the global discussion, there is no Brazilian data regarding opioids consumption, addiction or fatal intoxication cases. The aim of this work was to develop, validate and applied an analytical method based on liquid chromatography-tandem mass spectrometry for determination of fentanyl and seven analogues (acetyl norfentanyl, acetyl fentanyl, thiofentanyl, acrylfentanyl, furanylfentanyl, carfentanil and valerylfentanyl) in postmortem blood samples, to the routine analysis of the Forensic Toxicology Laboratory of São Paulo State Police. Linearity was evaluated from 1-500 ng mL-1 (correlation coefficient (r) value (r ≥ 0.99), 1/x weight linear regression), with limit of quantification of 1 ng mL-1. The method imprecision, bias and matrix effect were lower than 19.7%. No interference or carryover were observed, and extraction yield was greater than 57.7%. Analysis of postmortem blood samples (n = 1,359) showed that fentanyl was the most frequently detected opioid. The developed method proved to be useful for routine analysis of the Forensic Toxicology Laboratory. users crisis, crisis , crisis” drugs discussion consumption cases develop chromatographytandem chromatography tandem norfentanyl thiofentanyl acrylfentanyl furanylfentanyl valerylfentanyl Police 1500 500 1-50 mL1 mL mL- correlation r 0.99, 099 0.99 0 99 0.99) 1x x regression, regression regression) mL1. 1. imprecision 197 19 7 19.7% observed 577 57 57.7% n 1,359 1359 359 150 50 1-5 09 0.9 9 19.7 5 57.7 1,35 135 35 15 1- 0. 19. 57. 1,3 13 3 1,

Resumo O mamão é uma fruta climatérica, amadurecendo rapidamente após a colheita devido à produção de etileno e aumento da taxa respiratória. Esse amadurecimento rápido resulta no amolecimento dos tecidos da fruta, reduzindo a vida útil. O pré-resfriamento serve como uma alternativa para minimizar o amadurecimento da fruta e as perdas pós-colheita, reduzindo o metabolismo. Este estudo teve como objetivo avaliar o efeito do pré-resfriamento na qualidade e conservação do mamão 'Tainung I' Formosa. Mamões no estágio de maturação II foram obtidos de um pomar comercial com produção convencional. O design experimental foi um esquema de parcelas divididas completamente aleatório 4×6, com tratamentos de pré-resfriamento (Controle, sem tratamento de pré-resfriamento; pré-resfriamento a 15 °C em uma câmara fria; pré-resfriamento a 7 °C em uma câmara fria; e resfriamento por ar forçado a 7 °C) na parcela, e dias de armazenamento (0, 7, 14, 21, 28 e 35 dias) na subparcela. O pré-resfriamento retardou efetivamente o amadurecimento e a senescência do mamão Formosa, reduzindo a perda de cor verde e firmeza. Independentemente do tratamento utilizado, lesões por frio e incidência de fungos do gênero Fusarium e Alternaria limitaram a vida útil do mamão 'Tainung I' Formosa até 21 dias de armazenamento. Além disso, o surgimento de regiões endurecidas na polpa comprometeu a qualidade sensorial das frutas, exigindo investigação adicional sobre as causas desse distúrbio. climatérica respiratória préresfriamento pré póscolheita, póscolheita pós colheita, pós-colheita metabolismo Tainung I convencional 46 4 6 4×6 Controle, Controle (Controle 1 C fria parcela 0, 0 (0 14 2 3 subparcela firmeza utilizado disso frutas distúrbio 4× (

Abstract Papaya is a climacteric fruit, rapidly ripening after harvesting due to ethylene production and increased respiratory rate. This swift ripening results in softening of fruit tissues, shortening the fruit shelf life. Pre-cooling serves as an alternative to minimize fruit ripening and post-harvest losses by reducing metabolism. This study aimed to evaluate the effect of pre-cooling on the quality and conservation of Formosa 'Tainung I' papaya. Papayas at maturation stage II were obtained from a commercial orchard with conventional production. The experimental design was a completely randomized 4×6 split-plot scheme, with pre-cooling treatments (Control, without pre-cooling treatment; pre-cooling at 15 °C in a cold chamber; pre-cooling at 7 °C in a cold chamber; and forced-air cooling at 7 °C) in the plot, and days of storage (0, 7, 14, 21, 28, and 35 days) in the subplot. Pre-cooling effectively delayed the ripening and senescence of Formosa papaya, reducing the loss of green color and firmness. Regardless of the treatment used, chilling injury and incidence of fungi from the genus Fusarium and Alternaria limited the shelf life of Formosa 'Tainung I' papaya up to 21 days of storage. Additionally, the appearance of hardened regions in the pulp compromised the sensory quality of the fruits, necessitating further investigation into the causes of this disorder. rate tissues Precooling Pre postharvest post harvest metabolism precooling pre Tainung I 46 4 6 4× splitplot split plot scheme Control, Control (Control 1 C chamber forcedair forced air 0, 0 (0 14 28 3 subplot firmness used 2 Additionally fruits disorder (

RESUMO: A obesidade é considerada um processo inflamatório crônico que está relacionada ao comprometimento metabólico, dificuldade respiratória e doenças cardiovasculares. Em gatos, poucos estudos avaliaram as implicações da obesidade no sistema cardiovascular e a literatura é controversa. Portanto, o objetivo deste trabalho é detectar as alterações pressóricas, eletrocardiográficas e morfofuncionais em gatos com sobrepeso e obesidade. Quarenta e cinco animais, após avaliação clínica e laboratorial, foram selecionados para o estudo. Os gatos foram separados conforme o escore de condição corporal (ECC) em três grupos (controle, sobrepeso e obesidade). Todos os animais realizaram mensuração de pressão arterial, eletrocardiograma e ecocardiograma transtorácico. Os resultados foram apresentados como média ± desvio padrão (DP). Os dados foram considerados estatisticamente significativos se p<0,05. O software GraphPad Prism® 7.04 foi usado para análises estatísticas. A pressão arterial média dos gatos obesos era maior que nos animais com peso ideal (CT 123,60 ± 8,97mmHg vs OB 143,00 ± 22,12mmHg, p<0,0138), porém não se detectou hipertensão. No eletrocardiograma, a duração da onda P (CT 33,67 ± 1,56ms vs OB 37,76 ± 2,76ms; p<0,0003) e complexo QRS (CT 48,14 ± 2,56ms vs OB 54,48 ± 5,51ms; p<0,002) foi significativamente maior no grupo obeso. Não houve alterações ecocardiográficas significativas. Houve correlação direta da pressão arterial com o ECC (r:0,36, p<0,01). A onda P correlacionou-se positivamente com o ECC (r:0,56, p<0,0001). Do mesmo modo, o complexo QRS se correlacionou diretamente com o ECC (r:0,52, p<0,0003). Os resultados indicam que a obesidade em gatos pode afetar diretamente o sistema cardiovascular, promovendo alterações pressóricas e eletrocardiográficas. Sendo assim, é indispensável o acompanhamento do sistema cardiovascular dos gatos com obesidade.

ABSTRACT: Obesity is considered a chronic inflammatory process that is related to metabolic impairment, respiratory distress, and cardiovascular disease. In cats, few studies have evaluated the implications of obesity on the cardiovascular system, and the existing literature is controversial. Therefore, the aim of this study is to detect pressure, electrocardiographic, and morphofunctional changes in overweight and obese cats. After clinical and laboratory evaluation, 45 animals were selected for the study. Cats were separated according to body condition score (BCS) into three groups (control, overweight, and obese). All animals underwent blood pressure measurement, electrocardiogram, and transthoracic echocardiogram. Results are presented as mean ± standard deviation (SD). Data were considered statistically significant at p<0.05. GraphPad Prism® 7.04 software was used for statistical analyses. Mean arterial pressure in obese cats was higher than in animals with ideal weight (CT 123.60 ± 8.97mmHg vs OB 143.00 ± 22.12mmHg, p<0.0138), but hypertension was not detected. On the electrocardiogram, P wave duration (CT 33.67 ± 1.56ms vs OB 37.76 ± 2.76ms; p<0.0003) and QRS complex (CT 48.14 ± 2.56ms vs OB 54.48 ± 5.51ms; p<0.002) were significantly higher in the obese group. There were no significant echocardiographic changes. There was a direct correlation between blood pressure and BCS (r:0.36, p<0.01). The P wave was positively correlated with the BCS (r:0.56, p<0.0001). Likewise, the QRS complex correlated directly with the BCS (r:0.52, p<0.0003). The results indicate cat obesity can directly affect the cardiovascular system, promoting pressure and electrocardiographic changes.

A compreensão e interpretação do fenômeno envolvido no desenvolvimento da garrafa de Leiden integrou diferentes estudiosos e perspectivas, uma vez que o dispositivo desafiou as teorias sobre eletricidade do século XVIII, levando os filósofos naturais a um intenso debate e produções experimentais. Neste trabalho, trazemos um comparativo dos pressupostos de Benjamin Franklin (1706–1790), Franz Ulrich Theodosius Aepinus (1724–1802) e Jean-Antoine Nollet (1700–1770), para explicar como e por que a garrafa fornecia eletricidade. Com a análise das três explicações, podemos comparar suas semelhanças e principalmente diferenças, explicitando os diferentes métodos utilizados para construção de cada teoria. Entendemos que este tipo de estudo histórico contribui em discussões necessárias ao Ensino de Ciências quanto à complexidade do conhecimento científico. perspectivas XVIII experimentais trabalho 1706–1790, 17061790 1706–1790 , 1706 1790 (1706–1790) 1724–1802 17241802 1724 1802 (1724–1802 JeanAntoine Jean Antoine 1700–1770, 17001770 1700–1770 1700 1770 (1700–1770) explicações diferenças teoria científico 1706179 1706–179 170 179 (1706–1790 1724–180 1724180 172 180 (1724–180 1700177 1700–177 177 (1700–1770 170617 1706–17 17 (1706–179 1724–18 172418 18 (1724–18 170017 1700–17 (1700–177 17061 1706–1 1 (1706–17 1724–1 17241 (1724–1 17001 1700–1 (1700–17 1706– (1706–1 1724– (1724– 1700– (1700–1 (1706– (1724 (1700– (1706 (172 (1700 (170 (17 (1 (

The understanding and interpretation of the phenomenon involved in the development of the Leiden jar integrated different scholars and perspectives, as the device challenged 18th century theories about electricity, leading natural philosophers to intense debate and experimental productions. In this work, we compare the assumptions of Benjamin Franklin (1706–1790), Franz Ulrich Theodosius Aepinus (1724–1802) and Jean-Antoine Nollet (1700–1770), to explain how and why the bottle supplied electricity. With the analysis of the three explanations, we can compare their similarities and mainly differences, explaining the different methods used to construct each theory. We understand that this type of historical study contributes to discussions necessary for Science Teaching regarding the complexity of scientific knowledge. perspectives th electricity productions work 1706–1790, 17061790 1706–1790 , 1706 1790 (1706–1790) 1724–1802 17241802 1724 1802 (1724–1802 JeanAntoine Jean Antoine 1700–1770, 17001770 1700–1770 1700 1770 (1700–1770) explanations differences theory knowledge 1706179 1706–179 170 179 (1706–1790 1724–180 1724180 172 180 (1724–180 1700177 1700–177 177 (1700–1770 170617 1706–17 17 (1706–179 1724–18 172418 18 (1724–18 170017 1700–17 (1700–177 17061 1706–1 1 (1706–17 1724–1 17241 (1724–1 17001 1700–1 (1700–17 1706– (1706–1 1724– (1724– 1700– (1700–1 (1706– (1724 (1700– (1706 (172 (1700 (170 (17 (1 (

ABSTRACT Follicular thyroid cancers account for 15%-20% of all thyroid tumors. Choroidal metastases secondary to follicular thyroid cancer rarely occur. Herein, we report the case of an 85-year-old woman who presented choroidal metastasis from a follicular thyroid carcinoma in the right eye 7 years after total thyroidectomy and underwent enucleation. To confirm the diagnosis and primary tumor site, histopathological, and immunohistochemical examinations were performed. One year later, she presented metastasis in the contralateral eye. Few similar cases have been described in the literature. 15%20% 1520 15% 20% 15 20 15%-20 tumors occur Herein 85yearold yearold 85 old enucleation site histopathological performed later literature 15%20 152 1 2 15%-2 8 15%2 15%-

RESUMO: A tuberculose bovina é uma doença zoonótica com distribuição global. O objetivo do presente trabalho foi descrever a prevalência da enfermidade em bovinos através de uma revisão sistemática e meta-análise em estudos realizados no mundo. A pesquisa consistiu em uma revisão sistemática de literatura seguindo os preceitos da metodologia “Preferred Reporting Items for Systematic Reviews and Meta-Analyses” (PRISMA). Estudos transversais que descreveram a prevalência da enfermidade utilizando o método de diagnóstico através da prova intradérmica com derivado proteico purificado (PPD) bovino e aviário foram selecionados. O processo de identificação dos artigos foi desenvolvido nas bases de dados PubMed, ScienceDirect, Scopus e Web of Science. Do total de estudos encontrados (n=1.839), 60 atenderam a todos os critérios e foram incluídos na presente revisão. A prevalência geral encontrada foi de 3,27% (2,11-5,05%) para animais e 18,09% (11,20-27,90%) para rebanhos. Análises de fatores de riscos para a tuberculose em bovinos foi encontrada ou realizada em 50 estudos. A heterogeneidade identificada entre os trabalhos incluídos nesta revisão era esperada tendo em vista as diferenças relacionadas aos desenhos de pesquisa, anos de publicação dos estudos e a quantidade de animais amostrados. É necessária a avaliação da introdução de novos testes de diagnóstico ante-mortem aos programas de controle e erradicação que, combinados com os testes alérgicos, possam identificar o maior número de animais verdadeiramente positivos para a enfermidade.

ABSTRACT: Bovine tuberculosis is a zoonotic disease with global distribution. This study aimed to describe its prevalence in cattle through a systematic review and meta-analysis of studies conducted all around the world. The research consisted of a systematic literature review following the precepts of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Cross-sectional studies that described the prevalence of the disease using the diagnostic method through an intradermal test with bovine and avian purified protein derivative (PPD) were selected. Identifying articles was performed in the PubMed, ScienceDirect, Scopus, and Web of Science databases. Of the total number of studies found (n=1,839), 60 met all criteria and were included in this review. The overall prevalence was 3.27% (2.11-5.05%) for animals and 18.09% (11.20-27.90%) for herds. Analysis of risk factors for tuberculosis in cattle was found or performed in 50 studies. The heterogeneity identified among the works included was expected, given the differences in research design, year of publication, and the number of animals sampled. It is necessary to evaluate the insertion of new ante mortem diagnostic tests into control and eradication programs, which, combined with allergic tests, may identify the largest number of animals that presented an actual positive for the disease.

This study presents the synthesis and characterization of five Schiff bases derived from the reaction of 4-(2-aminoethyl)-benzenesulfonamide (compound 1) with corresponding aldehydes, (benzaldehyde, 2-pyridinecarboxaldehyde, 2-quinolinecarboxaldehyde, 8-hydroxy2-quinolinecarboxaldehyde and 4-imidazolecarboxaldehyde, for compounds 2-6, respectively). Characterization was performed by various spectroscopic techniques and supported by density functional theory (DFT) calculations. The crystal structures revealed how the substituent groups influenced the present supramolecular interactions. Compounds 1-4 and 6 showed no cytotoxicity to BHK-21 and VERO E6 cells at the highest concentration of 50 µmol L-1, while compound 5 was cytotoxic at this concentration. Compound 5 was active against the Chikungunya virus at the concentration of 10 µmol L-1, highlighting the effect of the 8-hydroxyquinoline substituent for the antiviral activity. For Zika virus, compound 6 was the only one active at 50 µmol L-1. The results suggest the potential of combining sulfonamides with other chemotypes for further development of antiviral agents, especially in the treatment of arboviral diseases. 42aminoethylbenzenesulfonamide aminoethylbenzenesulfonamide 4 2 aminoethyl benzenesulfonamide 1 aldehydes benzaldehyde, benzaldehyde (benzaldehyde 2pyridinecarboxaldehyde, 2pyridinecarboxaldehyde pyridinecarboxaldehyde pyridinecarboxaldehyde, 2-pyridinecarboxaldehyde 2quinolinecarboxaldehyde, 2quinolinecarboxaldehyde quinolinecarboxaldehyde quinolinecarboxaldehyde, 2-quinolinecarboxaldehyde 8hydroxy2quinolinecarboxaldehyde hydroxyquinolinecarboxaldehyde 8 hydroxy2 hydroxy 4imidazolecarboxaldehyde, 4imidazolecarboxaldehyde imidazolecarboxaldehyde imidazolecarboxaldehyde, 4-imidazolecarboxaldehyde 26, 26 6, 2-6 respectively. respectively . respectively) DFT (DFT calculations interactions 14 1- BHK21 BHK 21 BHK-2 E L1, L1 L 1, L-1 8hydroxyquinoline hydroxyquinoline activity L1. 1. agents diseases 2- BHK2 BHK- L-

Abstract Olanzapine (OLZ) is an antipsychotic medication used to treat postpartum psychiatric symptoms. It aimed to evaluate the effects of administering OLZ to lactating rats on testicular parameters of adult Wistar rats. Mothers received 2.5, 5 or 10 mg/kg until weaning. Adult male rats showed decrease in body weight, weight of testes, epididymis, prostate, seminal gland and gonadosomatic index when higher doses of OLZ were administered. Testicular volumetric parameters, as well as the length of seminiferous tubules, were also reduced in animals treated with the highest doses of OLZ. The diameter of the seminiferous tubules and the height of the seminiferous epithelium were reduced. There was also a relevant decrease in the population of Sertoli cells and a relevant reduction in the volume of individual Leydig cells. Histopathological analysis of the testes showed lesions compatible with testicular degeneration in rats treated with the highest dose of OLZ. There was a significant reduction in plasma testosterone levels in all treatments. It is noted, therefore, that the adverse impact on the testes of the highest doses of the drug during the neonatal period persisted into adulthood, with the dose of 2.5 mg/kg of OLZ proving to be safer than the others.
