A new class of deep eutectic solvents (DES) was used in the extraction of levodopa (L-dopa) present in Mucuna cinerea, which has been termed “green” or “designer” solvents, with notable productive and economic/environmental benefits. The seeds of Mucuna cinerea were prepared and submitted to extraction with heating and agitation in a solvent mixture of DES with citric acid, urea, or glycerol. The extracts were analyzed by high performance liquid chromatography (HPLC) which confirmed the efficiency of DES in extracting L-dopa. These extractions were carried out to determine the L-dopa extracts in DES with regard to the induction of cellular response activity, demonstrating the synergy between L-dopa and DES. The DES-glycerol extract exhibited a higher proliferative activity than commercial L-dopa after 24 h of treatment. The human glandular kallikrein-1 gene (hGK3) demonstrated higher expression in the treatment with the DES-urea, while the G protein-coupled receptor kinase-6 gene (GRK6) showed higher expression for all extracts compared to commercial L-dopa, with a higher value obtained for DES glycerol, followed by DES urea extract. The DES extraction method is therefore promising and unprecedented, confirming its possible use in the replacement of expensive solvents, supporting the use of ecologically viable DES in the extractions of other plant species.

Resumo O menor teor de lignina em espécies de plantas com potencial energético resulta na maior facilidade de quebra da celulose, disponibilizando glicose para geração de etanol. Porém, maiores teores de lignina representa um fator de resistência ao ataque de insetos. O objetivo deste trabalho foi avaliar como importantes pragas do sorgo energia, Diatraea saccharalis e Spodoptera frugiperda, se comportam quanto à alimentação e desempenho em sorgo bmr-6, um genótipo mutante com menor concentração de lignina. Foram realizados experimentos em laboratório e casa de vegetação, avaliando o desenvolvimento destas pragas nos híbridos de sorgo biomassa bmr 007, 008, TX635 e seus respectivos genótipos isogênicos convencionais (sem o gene bmr). O teor de lignina foi maior nos híbridos não bmr, mas nos parâmetros avaliados nos insetos, houve variação entre os tratamentos, não sendo consistente em apenas um híbrido e nem por ser ou não bmr. A menor sobrevivência de S. frugiperda foi verificada no híbrido BR008 tanto bmr quanto não bmr. As notas de injúria por S. frugiperda no sorgo em casa de vegetação foram altas (>7) em todos os tratamentos. Para D. saccharalis, não houve diferença significativa para a sobrevivência larval em laboratório, mas em casa de vegetação o híbrido BR007 tanto bmr quanto não bmr proporcionaram maior sobrevivência. Diante da necessidade de diversificar a matriz energética e o fato de que não foi comprovada neste estudo maior suscetibilidade dos híbridos bmr a ambas as pragas, estes resultados são promissores para o cultivo desses híbridos de sorgo biomassa para produção de biocombustíveis.
Abstract The lower lignin content in plants species with energy potential results in easier cellulose breakdown, making glucose available for ethanol generation. However, higher lignin levels can increase resistance to insect attack. The objective of this work was to evaluate the susceptibility of a bmr-6 biomass sorghum (a mutant genotype with a lower concentration of lignin) to important pests of energy sorghum, Diatraea saccharalis and Spodoptera frugiperda. Experiments were performed in the laboratory and greenhouse to evaluate the development of these pests on the biomass sorghum bmr hybrids BR007, BR008, and TX635 and their respective conventional near-isogenic genotypes (without the bmr gene). The lignin content was higher in non-bmr hybrids, but the evaluated insect variables varied between treatments, not being consistent in just one hybrid or because it is bmr or not. The lowest survival of S. frugiperda was observed in the BR008 hybrid, both bmr and non-bmr. The S. frugiperda injury scores on plants in the greenhouse were high (>7) in all treatments. For D. saccharalis, there was no difference in larval survival in the laboratory, but in the greenhouse, the BR007 hybrid, both bmr and non-bmr, provided greater survival. Due the need to diversify the energy matrix and the fact that greater susceptibility of the bmr hybrids to either pests was not found in this study, these results hold promise for cultivation of these biomass sorghum hybrids for the production of biofuels.

RESUMO Este estudo avaliou o efeito da coalimentação com ração comercial e alimentos vivos (enriquecidos ou não com microalgas) no crescimento e na sobrevivência das larvas de Trachelyopterus galeatus. Foram realizados cinco tratamentos: ração comercial como controle (F); náuplios de artêmia (BS); náuplios de artêmia enriquecidos com microalga Chaetoceros sp. (BSM); ração combinada com náuplios de artêmia (F+BS) e ração combinada com náuplios de artêmia enriquecidos com microalga (F+BSM). As larvas (5,00±0,02mg e 5,95±0,33mm) foram criadas por 30 dias. Não houve diferenças significativas (P>0,05) na qualidade da água entre os tratamentos, mas houve diferenças significativas no peso, no ganho de peso e na sobrevivência. Os tratamentos F+BS e F+BSM, que envolveram coalimentação, mostraram os melhores resultados em peso final (0,168±0,004g e 0,169±0,007g) e em ganho de peso (0,1278±0,004g e 0,1294±0,007g), respectivamente. Os tratamentos com alimentos vivos, enriquecidos ou não, mostraram altas taxas de sobrevivência acima de 73%, sem diferenças significativas entre eles. Por outro lado, o uso exclusivo de ração resultou em baixa sobrevivência (36,7±9,53%), indicando que isso pode resultar em baixo crescimento e inviabilizar a produção de larvas de T. galeatus. microalgas galeatus F (F) BS (BS) sp BSM (BSM) FBS (F+BS F+BSM.

ABSTRACT This study evaluated the effect of co-feeding with commercial feed and live food (enriched or not with microalgae) on the growth and survival of Trachelyopterus galeatus larvae. Five treatments were carried out: commercial feed as a control (F); brine shrimp nauplii (BS); brine shrimp nauplii enriched with Chaetoceros sp. Microalgae (BSM); combined feed with brine shrimp nauplii (F+BS) and combined feed with brine shrimp nauplii enriched with microalgae (FBSM). The larvae (5.00±0.02 mg and 5.95±0.33mm) were reared for 30 days. There were no significant differences (P>0.05) in water quality between treatments, but there were significant differences in weight, weight gain and survival. The F+BS and F+BSM treatments, which involved co-feeding, showed the best results in final weight (0.168±0.004g and 0.169±0.007g) and weight gain (0.1278±0.004 g and 0.1294±0.007g), respectively. The treatments with live food, enriched or not, showed high survival rates of over 73%, with no significant differences between them. On the other hand, the exclusive use of feed resulted in low survival (36.7 ± 9.53%), indicating that this may result in low growth and make the production of T. galeatus larvae unfeasible. cofeeding co feeding out F (F) BS (BS) sp BSM (BSM) FBS (F+BS FBSM.

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.

Essential oils (EO) have diverse applications, such as antibacterial and antifungal activity. However, they are susceptible to oxidation in the presence of air, light, and moisture. In addition, they are thermally unstable. In this sense, it is necessary to develop techniques to increase the lifespan of EO. In this work, EO was obtained from cloves and characterized by different techniques. The major compounds found were eugenol (83%), eugenol acetate (9%), and β-caryophyllene (8%). The EO was encapsulated by extrusion using a microfluidic device. The sodium alginate was used as wall material, and the CaCl2 solution was used as a crosslinking agent. The microcapsule presented sizes of 164.7 ± 0.3 μm, with an encapsulation yield of 64 ± 14%. Functional characteristic groups of EO were observed in the microcapsule by infrared and Raman spectroscopies. The microcapsule increased the thermal decomposition of the EO from 162 to 230 °C. Release kinetics of the capsule was performed, with an equilibrium time of 72 h and release of 54% of the EO. Finally, the pure EO and encapsulated EO-microcapsules were applied in the Aedes aegypti larvae control, showing mean lethal concentration necessary to eliminate 50% (LC50) values of 74.4 and 96.9 μg mL-1 and lethal concentration necessary to eliminate 90% (LC90) of 106.2 and 133.3 μg mL-1 for pure EO and encapsulated EO, respectively. Therefore, it was concluded that these microcapsules have the potential for application in the Aedes aegypti larvae control.

ABSTRACT Background: Omalizumab (OMA) is approved for antihistamine resistant chronic spontaneous urticaria (CSU). The possibility of self-administration (SA), is particularly convenient in current pandemic scenario, avoiding commutements to the hospital. Objectives: CSU control, SA safety, satisfaction, and cost reduction for patients under OMA SA therapy, during a period ≥ 12 weeks and after 2 training sessions in Outpatient Hospital Care (OHC) were evaluated between January and June 2021. Methods: A questionnaire (30 questions) was applied for the characterization of clinical/demographic data, therapy, adverse reactions (AR) and advantages/concerns related to OMA SA. Clinical evaluation of CSU was performed in T0 (last administration in OHC) and T1 (at12 weeks on SA), by urticaria activity score in the last 7 days (UAS7), urticaria control test (UCT) and dermatology life quality index (DLQI). Results: Twenty-five patients with a mean CSU duration of 7.4 ±3.9 years and under OMA for 3.2 ±1.9 years were included. At the time of the questionnaire, 52% had already 3 SA of OMA 300mg, with variable periodicity between 4/4 week (44%) and 8/8 week (12%); 40% without antihistamine H1 (anti-H1) therapy associated. In 88% OMA was SA by patient himself. 64% perceived equal pain intensity with SA than in OHC administration. No serious AR were reported. Regarding the control of CSU, there were no statistically significant differences between scores in T0 and T1. SA was considered advantageous by all patients, being valued the reduction of time/costs. About 48% reported some concerns with SA, especially in OMA manipulation. The majority (76%) considered a simple and practical procedure, valuing initial training sessions in OHC. For 52% there was no need for further improvement, while the simplification of the OMA delivery process was proposed by 28% of patients. Conclusions: OMA SA had a positive impact on satisfaction in patients with CSU, keeping up the good control and therapeutic safety.
RESUMO Fundamentos: O omalizumab (OMA) está aprovado para a urticária crónica espontânea (UCE) refratária aos anti-histamínicos. A possibilidade de autoadministração (AA) de OMA evita deslocações ao hospital, particularmente relevante em tempo de pandemia. Objetivos: Avaliaram-se o controlo da UCE, segurança da AA de OMA, grau de satisfação e redução dos custos para os doentes sob OMA em AA por período igual ou superior a 12 semanas e após duas sessões de ensino em Hospital de Dia (HD), entre janeiro e junho de 2021. Métodos: Aplicou-se um questionário(30 perguntas) visando a caracterização clínica/demográfica, terapêutica, reações adversas (RA), vantagens/preocupações percecionadas e avaliação de UCE em T0 (última administração em HD) e T1 (12 semanas em AA), por score de atividade da urticária nos últimos sete dias (UAS7), teste de controlo da urticária (UCT) e índice de qualidade de vida em dermatologia (DLQI). Resultados: Incluíram-se 25 doentes com tempo médio de UCE de 7,4 ±3,9 anos e duração do tratamento com OMA de 3,2 ±1,9 anos. À data do questionário, 52% tinham 3 AA de OMA 300mg, com periodicidade variável entre 4/4 semanas (44%) e 8/8 semanas (12%); 40% sem anti-histamínico associado. Em 88% administrado pelo próprio; 64% relatou igual intensidade de dor na AA face à administração em HD. Não se registaram RA graves. No controlo da UCE não se verificaram diferenças estatisticamente significativas nos scores entre T0 e T1. Todos consideraram a AA vantajosa, valorizando sobretudo a diminuição do tempo/custos despendidos. 48% referiu algum receio na AA, sobretudo na manipulação do OMA. A maioria (76%) considerou o processo simples e prático, valorizando os ensinos prévios em HD; 52% considerou não haver aspetos a melhorar; das sugestões apontadas, 28% referiam-se à simplificação do processo de entrega do OMA. Conclusões: O OMA em AA apresentou impacto positivo na satisfação dos doentes com UCE, mantendo-se o controlo da UCE e segurança terapêutica.

RESUMO O desempenho dos subsoladores pode ser influenciado pelos restos culturais no solo através dos diferentes tipos de cobertura vegetal. Em qualquer um desses sistemas de cobertura, o uso de subsoladores para descompactação altera as propriedades físicas do solo. O presente estudo teve como objetivo avaliar os atributos físicos do solo em tipos de manejo sob diferentes velocidades de deslocamento e profundidades na operação de subsolagem. O experimento foi conduzido no IF Goiano, Campus Morrinhos, Goiás, Brasil. O delineamento inteiramente casualizado foi usado em esquema de parcelas subdivididas com 12 tratamentos e cinco repetições, totalizando 60 plarcelas. Os fatores corresponderam a duas áreas de manejo (sequeiro e pastagem), duas velocidades de operação de subsolagem (2,5 e 4,5 km h-1) e três profundidades do solo (0,00-0,015; 0,15-0,30 e 0,30-0,45 m). A parcela principal foi constituída pelas duas áreas de manejo e a subparcela a combinação dos outros dois fatores. Foram avaliados a resistência à penetração, densidade do solo, teor de água, mobilização do solo e expansão volumétrica do solo. Posteriormente, os valores encontrados foram submetidos à análise de variância e teste de Tukey p ≤ 0,05. A resistência à penetração e a densidade aparente foram diferentes antes e após a subsolagem. As velocidades de subsolagem alteraram os valores de resistência à penetração e mobilização do solo. As áreas de pastagem apresentaram maior resistência à penetração das raízes e proporcionaram menor teor de água e favoreceram maior expansão volumétrica do solo.
ABSTRACT Subsoiler performance can be influenced by crop residue in the soil through different types of vegetation cover. In any of these cover systems, the use of subsoilers for decompaction changes soil physical properties. The present study aimed to evaluate soil physical properties in different management systems using several subsoiling speeds and soil depths. The experiment was conducted at IF Goiano, Morrinhos Campus, Goiás state, Brazil. A completely randomized design was used in a split-plot scheme with 12 treatments and five replicates, totaling 60 plots. The factors corresponded to two management areas (rainfed and pasture), two subsoiling speeds (2.5 and 4.5 km h-1) and three soil depths (0.00-0.015; 0.15-0.30 and 0.30-0.45 m). The main plot consisted of the two management areas and the subplot the combination of the other two factors. Penetration resistance, bulk density, water content, soil mobilization and soil volumetric expansion were evaluated. The results were then submitted to analysis of variance and Tukey’s test (p ≤ 0.05). Penetration resistance and bulk density differed before and after subsoiling. The subsoiling speeds altered penetration resistance and soil mobilization. Pasture areas showed greater root penetration resistance, provided lower water content and favored greater soil volumetric expansion.

Abstract Scientific diving (SD) is defined as any diving activity that applies scientific procedures to produce subsidies for studies and technical works in underwater environments. The first report of an underwater scientific study in Brazil dates to the 19th century, in the Abrolhos reefs. Currently, in Brazil, scientific diving has been performed in various areas, from shallow coastal regions to remote and sometimes hard-to-reach places, such as oceanic islands, flooded caves, and icy areas like Antarctica. However, the regulation of SD in Brazil still lacks more concrete actions towards an effective and efficient self-regulation that offers physical safety to practitioners and institutional safeguards for organizations that use it in their research projects. Thus, this article aims to contribute to a better understanding of this critical issue in Brazil and to serve as a reference and incentive for the training of professionals and the development of these activities in the country. It includes: 1) a historical review of SD; 2) a diagnosis of the training and application of SD in Brazil; 3) the evolution of marine sciences in Brazil from the perspective of SD; 4) a review of the use of environmental assessment and underwater conservation techniques in oceans and internal waters; 5) an analysis of the evolution of scientific diver training in Brazil, including a diagnosis on training; 6) the history and updates of the rules, regulations, and safety of SD. Given all the potential of diving combined with specific techniques for research, monitoring, and marine and limnic science in Brazil, we aim to understand the evolution of scientific diving teaching and to outline perspectives in the country, as it is crucial for the training of qualified scientists capable of performing these underwater tasks. Finally, we present future plans for the development of this activity in Brazil from the point of view of research and the labor market.

BACKGROUND A positive Trypanosoma cruzi polymerase chain reaction (PCR) is associated with a worse prognosis in patients with chronic Chagas disease (CD). OBJECTIVES To study the association of clinical, electrocardiographic, and echocardiographic characteristics and biomarker blood levels with positive T. cruzi PCR in chronic CD. METHODS This is a single-centre observational cross-sectional study. Positive T. cruzi PCR association with clinical, electrocardiographic, and echocardiographic characteristics, and biomarker blood levels were studied by logistic regression analysis. p values < 0.05 were considered significant. FINDINGS Among 333 patients with chronic CD (56.4% men; 62 ± 10 years), T. cruzi PCR was positive in 41.1%. Stepwise multivariate logistic regression showed an independent association between positive T. cruzi PCR and diabetes mellitus {odds ratio (OR) 0.53 [95% confidence interval (CI) 0.30-0.93]; p = 0.03}, right bundle branch block [OR 1.78 (95% CI 1.09-2.89); p = 0.02], and history of trypanocidal treatment [OR 0.13 (95% CI 0.04-0.38); p = 0.0002]. Among patients with a history of trypanocidal treatment (n = 39), only four (10%) patients had a positive T. cruzi PCR. MAIN CONCLUSIONS Among several studied parameters, only diabetes mellitus, right bundle branch block, and history of trypanocidal treatment showed an independent association with positive T. cruzi PCR. History of trypanocidal treatment was a strong protective factor against a positive T. cruzi PCR. (PCR .

Resumo Os estuários são ecossistemas importantes devido a serviços ecológicos que fornecem, os quais conferem a função de berçário para muitas espécies de peixes e invertebrados, e também são utilizados como ambientes de extração e cultivo de moluscos. As ostras são animais que filtram a água para obtenção de oxigênio e nutrientes. Nesse processo podem bioacumular microorganismos e substâncias químicas em seus tecidos. O crescimento da malacocultura no Nordeste do Brasil fomenta a necessidade de identificar a sanidade das ostras cultivadas através da quantificação da microbiota potencialmente nociva acumulada nos animais. Portanto o presente trabalho visa quantificar e identificar bactérias e possíveis patógenos encontrados nos tecidos dos moluscos cultivados e nas suas águas de cultivo.

Abstract Estuaries are important ecosystems due to the ecological services they provide, acting as nurseries for many species of fish and invertebrates, and are also used as environments for the extraction and cultivation of mollusks. Oysters are animals that filter water to obtain oxygen and nutrients. In this process, they can bioaccumulate microorganisms and chemical substances in their tissues. The growth of mollusk culture in Northeastern Brazil requires the health identification of cultivated oysters through the quantification of the potentially harmful microbiota accumulated in the animals. Therefore, the present work aims to quantify and identify bacteria and possible pathogens found in the tissues of cultivated oysters and their culture waters. The Most Probable Number of Coliforms (MPN) in oysters and water were considered suitable according to the Brazilian current legislation, Vibrio sp. obtained low colonization and Salmonella sp. was not observed. The prevalence of microorganisms potentially pathogenic to oysters was 33.7%, highlighting metazoans and Nematopsis sp., however, the intensity of the infestation of these organisms was moderate. The low contamination of oysters demonstrates that this culture environment is promising for this activity. However, continuous environmental and sanitary monitoring is fundamental to guarantee the safety of the culture waters and the sustainability of aquaculture activities. provide invertebrates mollusks nutrients process Therefore MPN (MPN legislation sp observed 337 33 7 33.7% however moderate activity However activities 3 33.7 33.

Resumo O reparo por excisão de nucleotídeos (NER) atua reparando danos no DNA, como lesões causadas por cisplatina. A proteína Xeroderma Pigmentosum complementation group C (XPC) está envolvida no reconhecimento de danos pela via de reparação global do genoma pelo NER (GG-NER) e tem sido estudada em diferentes organismos devido à sua importância em outros processos celulares. Neste trabalho, estudamos proteínas do NER em Trypanosoma cruzi e Trypanosoma evansi, parasitos de humanos e animais, respectivamente. Modelos tridimensionais das proteínas XPC de T. cruzi e T. evansi foram feitos e observou-se poucas diferenças estruturais entre estas proteínas. Durante testes, a inserção do gene XPC de T. evansi (TevXPC) em T. cruzi resultou em crescimento celular mais lento em condições normais. Após o tratamento com cisplatina, T. cruzi superexpressando seu próprio gene XPC (TcXPC) foi capaz de recuperar as taxas de divisão celular mais rapidamente do que T. cruzi expressando o gene TevXPC. Com base nesses testes, sugere-se que TevXPC (sendo uma proteína exógena em T. cruzi) interfere negativamente nos processos celulares em que TcXPC (a proteína endógena) está envolvida. Isso provavelmente ocorreu pois TevXPC é capaz de interagir com algumas moléculas ou proteínas endógenas de T.cruzi, mas é incapaz de interagir com outras. Isso reforça a importância do correto funcionamento de XPC dentro da célula.
Abstract Nucleotide excision repair (NER) acts repairing damages in DNA, such as lesions caused by cisplatin. Xeroderma Pigmentosum complementation group C (XPC) protein is involved in recognition of global genome DNA damages during NER (GG-NER) and it has been studied in different organisms due to its importance in other cellular processes. In this work, we studied NER proteins in Trypanosoma cruzi and Trypanosoma evansi, parasites of humans and animals respectively. We performed three-dimensional models of XPC proteins from T. cruzi and T. evansi and observed few structural differences between these proteins. In our tests, insertion of XPC gene from T. evansi (TevXPC) in T. cruzi resulted in slower cell growth under normal conditions. After cisplatin treatment, T. cruzi overexpressing its own XPC gene (TcXPC) was able to recover cell division rates faster than T. cruzi expressing TevXPC gene. Based on these tests, it is suggested that TevXPC (being an exogenous protein in T. cruzi) interferes negatively in cellular processes where TcXPC (the endogenous protein) is involved. This probably occurred due interaction of TevXPC with some endogenous molecules or proteins from T.cruzi but incapacity of interaction with others. This reinforces the importance of correctly XPC functioning within the cell.

RESUMO: A pelve, constituída pelo ílio, ísquio e púbis, forma o coxal, sendo este o maior dos ossos planos constituintes do esqueleto, com importante papel na fisiologia do parto. Vastamente estudada em animais domésticos, ainda existe muito à se investigar quanto a classificação anatômica nos animais selvagens, visando principalmente melhorar a compreensão do manejo reprodutivo das espécies. Tamandua tetradactyla é uma dessas espécies em que estudos morfológicos ainda são escassos, principalmente quando se trata de aspectos reprodutivos. Neste contexto realizamos a pelvimetria do T. tetradactyla por meio de imagens radiográficas para classificar anato-obstetricamente a pelve desta espécie classificando-a como dolicopélvica, sendo evidenciada homoscedasticidade das amostras. A verificação da existência de relação entre as variáveis estudadas pelo método estatístico dos coeficientes de Pearson mostrou correlação positivas de alta intensidade para os diâmetros estudados (P< 0,01). Assim, acreditamos que nossos achados poderão subsidiar futuros estudos reprodutivos nesta espécie.
ABSTRACT: The pelvis, formed by the ilium, ischium and pubis, forms the coxal, which is the largest of the flat bones of the skeleton, with an important role in the physiology of birth. Vastly studied in domestic animals, there is still much to be investigated regarding the anatomical classification in wild animals, mainly aiming to improve the understanding of the reproductive management of the species. Tamandua tetradactyla is one of these species in which morphological studies are still scarce, especially when it comes to reproductive aspects. In this context, we carried out the pelvimetry of T. tetradactyla using radiographic images to anatomically and obstetrically classify the pelvis of this species, classifying it as dolicopelvic, with evidence of homoscedasticity of the samples. Verification of the existence of a relationship between the variables studied by the statistical method of Pearson coefficients showed positive correlations of high intensity for the diameters studied (P < 0.01). Thus, we believed that our findings may support future reproductive studies in this species.

RESUMO As características agronômicas e físicas do milho são fundamentais para produtores e indústrias que utilizam este cereal como matéria-prima, pois, interferem nos processos de industrialização, rendimento e qualidade dos produtos finais. Desse modo, o objetivo com este estudo foi avaliar as características agronômicas e físicas do grão de híbridos de milho transgênicos e convencionais cultivados na primeira safra (verão) no Estado do Paraná. Foram instalados três experimentos, nas safras agrícolas 2017/18, 2018/19 e 2019/20. O delineamento experimental utilizado foi de blocos casualizados com oito híbridos: (Supremo Vip, Supremo, P30F53VYH, P30F53, P3456H, P3456, DKB290PRO3, DKB290) e três repetições. Foram avaliadas as características físicas dos grãos para fins industriais como a canjica, gérmen, vitreosidade, flutuação e peso hectolitro, e as características agronômicas como a porcentagem de grãos ardidos, peso de mil grãos e produtividade de grãos. A canjica e gérmen são influenciados pela escolha do híbrido e pela safra agrícola avaliada, em que os híbridos Supremo (convencional), Supremo Vip (transgênico) e P3456 (convencional) apresentaram os melhores resultados. As características físicas de flutuação, peso hectolitro e vitreosidade foram influenciadas pela escolha do híbrido e safra agrícola avaliada, destacando-se os híbridos Supremo (convencional), Supremo Vip (transgênico), P30F53 (convencional), P30F53 VYH (transgênico), P3456 (convencional), P3456 VYH (transgênico), com os melhores resultados. Os híbridos convencionais mostraram superioridade industrial comparados aos híbridos transgênicos para canjica, flutuação e vitreosidade.
ABSTRACT The agronomic and physical traits of corn are fundamental for producers and industries that use this cereal as a raw material since they interfere in the industrialization processes, yield, and quality of the final products. This study aimed to evaluate the agronomic and physical traits of the grain in transgenic and conventional corn hybrids grown in the first crop season (summer) in Paraná State. Three experiments were set up in 2017/18, 2018/19, and 2019/20 crop seasons. A randomized block design with three replications was used. Eight hybrids (Supremo Vip, Supremo, P30F53VYH, P30F53, P3456H, P3456, DKB290PRO3, DKB290) were evaluated. The physical traits of grains for industrial purposes, such as grits, germ, vitreousness, flotation, and hectoliter weight, and the agronomic traits (percentage of rot grains, 1000-grain weight, and grain yield) were evaluated. The hybrids and crop seasons influence the industrial physical traits of grits and germ. The hybrids Supremo (conventional), Supremo Vip (transgenic), and P3456 (conventional) had the best results. The hybrids and crop season influenced the flotation, hectoliter weight, and vitreousness, highlighting the hybrids Supremo (conventional), Supremo Vip (transgenic), P30F53 (conventional), P30F53 VYH (transgenic), P3456 (conventional), P3456 VYH (transgenic), with the best results. The conventional hybrids showed industrial superiority compared to transgenic hybrids for grits, flotation, and vitreousness.

This guideline aimed to update the concepts and formulate the standards of conduct and scientific evidence that support them, regarding the diagnosis and treatment of the Cardiomyopathy of Chagas disease, with special emphasis on the rationality base that supported it.nbsp;
Chagas disease in the 21st century maintains an epidemiological pattern of endemicity in 21 Latin American countries. Researchers and managers from endemic and non-endemic countries point to the need to adopt comprehensive public health policies to effectively control the interhuman transmission of T. cruzi infection, and to obtain an optimized level of care for already infected individuals, focusing on diagnostic and therapeutic opportunistic opportunities.
nbsp;
Pathogenic and pathophysiological mechanisms of the Cardiomyopathy of Chagas disease were revisited after in-depth updating and the notion that necrosis and fibrosis are stimulated by tissue parasitic persistence and adverse immune reaction, as fundamental mechanisms, assisted by autonomic and microvascular disorders, was well established. Some of them have recently formed potential targets of therapies.nbsp;
The natural history of the acute and chronic phases was reviewed, with enhancement for oral transmission, indeterminate form and chronic syndromes. Recent meta-analyses of observational studies have estimated the risk of evolution from acute and indeterminate forms and mortality after chronic cardiomyopathy. Therapeutic approaches applicable to individuals with Indeterminate form of Chagas disease were specifically addressed. All methods to detect structural and/or functional alterations with various cardiac imaging techniques were also reviewed, with recommendations for use in various clinical scenarios. Mortality risk stratification based on the Rassi score, with recent studies of its application, was complemented by methods that detect myocardial fibrosis.nbsp;
The current methodology for etiological diagnosis and the consequent implications of trypanonomic treatment deserved a comprehensive and in-depth approach. Also the treatment of patients at risk or with heart failure, arrhythmias and thromboembolic events, based on pharmacological and complementary resources, received special attention. Additional chapters supported the conducts applicable to several special contexts, including t. cruzi/HIV co-infection, risk during surgeries, in pregnant women, in the reactivation of infection after heart transplantation, and others.nbsp; nbsp;nbsp;
Finally, two chapters of great social significance, addressing the structuring of specialized services to care for individuals with the Cardiomyopathy of Chagas disease, and reviewing the concepts of severe heart disease and its medical-labor implications completed this guideline.
Esta diretriz teve como objetivo principal atualizar os conceitos e formular as normas de conduta e evidências científicas que as suportam, quanto ao diagnóstico e tratamento da CDC, com especial ênfase na base de racionalidade que a embasou.
A DC no século XXI mantém padrão epidemiológico de endemicidade em 21 países da América Latina. Investigadores e gestores de países endêmicos e não endêmicos indigitam a necessidade de se adotarem políticas abrangentes, de saúde pública, para controle eficaz da transmissão inter-humanos da infecção pelo T. cruzi, e obter-se nível otimizado de atendimento aos indivíduos já infectados, com foco em oportunização diagnóstica e terapêutica.
Mecanismos patogênicos e fisiopatológicos da CDC foram revisitados após atualização aprofundada e ficou bem consolidada a noção de que necrose e fibrose sejam estimuladas pela persistência parasitária tissular e reação imune adversa, como mecanismos fundamentais, coadjuvados por distúrbios autonômicos e microvasculares. Alguns deles recentemente constituíram alvos potenciais de terapêuticas.
A história natural das fases aguda e crônica foi revista, com realce para a transmissão oral, a forma indeterminada e as síndromes crônicas. Metanálises recentes de estudos observacionais estimaram o risco de evolução a partir das formas aguda e indeterminada e de mortalidade após instalação da cardiomiopatia crônica. Condutas terapêuticas aplicáveis aos indivíduos com a FIDC foram abordadas especificamente. Todos os métodos para detectar alterações estruturais e/ou funcionais com variadas técnicas de imageamento cardíaco também foram revisados, com recomendações de uso nos vários cenários clínicos. Estratificação de risco de mortalidade fundamentada no escore de Rassi, com estudos recentes de sua aplicação, foi complementada por métodos que detectam fibrose miocárdica.
A metodologia atual para diagnóstico etiológico e as consequentes implicações do tratamento tripanossomicida mereceram enfoque abrangente e aprofundado. Também o tratamento de pacientes em risco ou com insuficiência cardíaca, arritmias e eventos tromboembólicos, baseado em recursos farmacológicos e complementares, recebeu especial atenção. Capítulos suplementares subsidiaram as condutas aplicáveis a diversos contextos especiais, entre eles o da co-infecção por T. cruzi/HIV, risco durante cirurgias, em grávidas, na reativação da infecção após transplante cardíacos, e outros.nbsp;nbsp;nbsp;
Por fim, dois capítulos de grande significado social, abordando a estruturação de serviços especializados para atendimento aos indivíduos com a CDC, e revisando os conceitos de cardiopatia grave e suas implicações médico-trabalhistas completaram esta diretriz.nbsp;

Abstract We evaluated the influence of a 32-day camping in Antarctica on physical performance and exercise-induced thermoregulatory responses. In Brazil, before and after the Antarctic camping, the volunteers performed an incremental exercise at temperate conditions and, two days later, an exercise heat stress protocol (45-min running at 60% of maximum aerobic speed, at 31°C and 60% of relative humidity). In Antarctica, core temperature was assessed on a day of fieldwork, and average values higher than 38.5°C were reported. At pre- and post-Antarctica, physiological (whole-body and local sweat rate, number of active sweat glands, sweat gland output, core and skin temperatures) and perceptual (thermal comfort and sensation) variables were measured. The Antarctic camping improved the participants’ performance and induced heat-related adaptations, as evidenced by sweat redistribution (lower in the chest but higher in grouped data from the forehead, forearm, and thigh) and reduced skin temperatures in the forehead and chest during the exercise heat stress protocol. Notwithstanding the acclimatization, the participants did not report differences of the thermal sensation and comfort. In conclusion, staying in an Antarctic camp for 32 days improved physical performance and elicited physiological adaptations to heat due to the physical exertion-induced hyperthermia in the field.
