RESUMO: O estudo de adaptabilidade, estabilidade e produtividade é importante para selecionar e recomendar genótipos superiores. Esse fato é particularmente válido para a introdução de cultivares de feijão comum no Rio de Janeiro, Brasil, cuja produção é ínfima e não atende a demanda interna. Assim, este trabalho teve como objetivo estimar parâmetros genéticos e ganhos de seleção e realizar uma seleção simultânea para adaptabilidade, estabilidade e produtividade de genótipos de feijão preto através de modelos mistos. O estudo foi realizado em três municípios do estado do Rio de Janeiro e em três anos agrícolas. Os ensaios foram instalados em delineamento de blocos casualizados com 11 genótipos e três repetições. Observou-se alta herdabilidade média (81%), acurácia seletiva (90%) e boas perspectivas de seleção. Também foram observados ganhos satisfatórios para a característica entre 1,03 e 9,49%. A seleção simultânea foi eficiente e permitiu selecionar duas linhagens de feijão preto CNFP (15290 e 15361) como sendo as mais produtivas, adaptáveis e estáveis e, portanto, têm potencial para serem lançadas como novas cultivares de feijão preto para o estado do Rio de Janeiro.

ABSTRACT: The study of adaptability, stability, and productivity is essential for selecting and recommending superior genotypes. This fact is particularly the case for the introduction of common bean cultivars in Rio de Janeiro, Brazil, whose production is negligible and does not meet the internal demand. Thus, this study estimated genetic parameters and selection gains and undertake a simultaneous selection for adaptability, stability, and productivity in black bean genotypes via mixed models. The investigation was carried out in three municipalities in the state of Rio de Janeiro during three crop years. The trials were set up in a randomized block design with 11 genotypes and three replications. High mean heritability (81%) and selection accuracy (90%), as well as good selection prospects, were observed. Gains between 1.03 and 9.49% were achieved for grain yield. Simultaneous selection was efficient, indicating two black bean lines (CNFP 15290 and CNFP 15361) as the most productive, adaptable, and stable. As such, these lines have the potential to be released as new black bean cultivars for the state of Rio de Janeiro.

Abstract To date, hydroxyurea is the only effective and safe drug that significantly reduces morbidity and mortality of individuals with Sickle cell disease. Twenty years of real-life experience has demonstrated that hydroxyurea reduces pain attacks, vaso-occlusive events, including acute chest syndrome, the number and duration of hospitalizations and the need for transfusion. The therapeutic success of hydroxyurea is directly linked to access to the drug, the dose used and adherence to treatment which, in part, is correlated to the availability of hydroxyurea. This consensus aims to reduce the number of mandatory exams needed to access the drug, prioritizing the requesting physician's report, without affecting patient safety. date disease reallife real life attacks vasoocclusive vaso occlusive events syndrome transfusion which part physicians physician s report safety

Abstract Background: Spinal ventral root injuries generate significant motoneuron degeneration, which hinders full functional recovery. The poor prognosis of functional recovery can be attributed to the use or combination of different therapeutic approaches. Several molecules have been screened as potential treatments in combination with surgical reimplantation of the avulsed roots, the gold standard approach for such injuries. Among the studied molecules, human natural killer-1 (HNK-1) stands out as it is related to the stimulation of motor axon outgrowth. Therefore, we aimed to comparatively investigate the effects of local administration of an HNK-1 mimetic peptide (mp-HNK-1) and systemic treatment with ursolic acid (UA), another HNK-1 mimetic, after ventral root avulsion and reimplantation with heterologous fibrin biopolymer (HFB). Methods: Female mice of the isogenic strain C57BL/6JUnib were divided into five experimental groups: Avulsion, Reimplantation, mp-HNK-1 (in situ), and UA (systemic treatment). Mice were evaluated 2 and 12 weeks after surgery. Functional assessment was performed every four days using the Catwalk platform. Neuronal survival was analyzed by cytochemistry, and glial reactions and synaptic coverage were evaluated by immunofluorescence. Results: Treatment with UA elicited long-term neuroprotection, accompanied by a decrease in microglial reactions, and reactive astrogliosis. The neuroprotective effects of UA were preceded by increased glutamatergic and GABAergic inputs in the ventral spinal cord two weeks after injury. However, a single application of mp-HNK-1 had no significant effects. Functional analysis showed that UA treatment led to an improvement in motor and sensory recovery. Conclusion: Overall, the results indicate that UA is neuroprotective, acting on glial cells and synaptic maintenance, and the combination of these findings led to a better functional recovery.

ABSTRACT Introduction: Protocols for obtaining the maximum threshold pressure have been applied with limited precision to evaluate inspiratory muscle endurance. In this sense, new protocols are needed to allow more reliable measurements. The purpose of the present study was to compare a new incremental ramp load protocol for the evaluation of inspiratory muscle endurance with the most used protocol in healthy individuals. Methods: This was a prospective cross-sectional study carried out in a single center. Ninety-two healthy individuals (43 men [22 ± 3 years] and 49 women [22 ± 3 years]) were randomly allocated to perform: (i) incremental ramp load protocol and (ii) incremental step loading protocol. The sustained pressure threshold (or maximum threshold pressure), maximum threshold pressure/dynamic strength index ratio, time until task failure, as well as difference between the mean heart rate of the last five minutes of baseline and the peak heart rate of the last 30 seconds of each protocol were measured. Results: Incremental ramp load protocol with small increases in the load and starting from minimum values of strength index was able to evaluate the inspiratory muscle endurance through the maximum threshold pressure of healthy individuals. Conclusion: The present study suggests that the incremental ramp load protocol is able to measure maximum threshold pressure in a more thorough way, with less progression and greater accuracy in the load stratification compared to the limited incremental step loading protocol and with a safe and expected cardiovascular response in healthy individuals.

ABSTRACT The objectives of this study were to estimate genetic parameters and the repeatability coefficient and to select clones of elephant grass from full-sib families. Fifteen clones and two commercial controls were evaluated in a randomized block design with three replications. Three measurements were taken at regular 10-month intervals. Genotypic variance was significant. The observed heritability based on the mean of the genotypes (0.58), coupled with the results of repeatability (0.53) and selection accuracy (0.76), demonstrates that the genotypes performance is constant between measurements. Thus, only three measurements are necessary to reliably select genotypes and obtain real genetic gains with selection. Among the 15 clones evaluated, six showed higher new means than those of the BRS Capiaçu and BRS Canará controls and can be used as parents and/or to compose value for cultivation and use experiments aimed at the release of cultivars for bioenergy production. fullsib full sib families replications 10month month 10 intervals significant 0.58, 058 0.58 , 0 58 (0.58) 0.53 053 53 (0.53 0.76, 076 0.76 76 (0.76) Thus 1 andor or production 05 0.5 5 (0.58 (0.5 07 0.7 7 (0.76 0.

BACKGROUND The Golden Syrian hamster (Mesocricetus auratus), Ferrets (Mustela putorius furo), and macaques have been described as useful laboratory animals naturally susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. OBJECTIVES To study the mechanism of lung injury, we describe the histopathological features of SARS-CoV-2 infection in Golden Syrian hamsters inoculated intranasally with the A.2 Brazilian strain. METHODS Hamsters were intranasally inoculated with the A.2 variant and euthanised at 3-, 5-, 10- and 15-days post-inoculation. The physical examination and body weight were recorded daily. Neutralising antibodies and viral RNA load of the respiratory tract were assessed during necropsies. FINDINGS The coronavirus disease 2019 (COVID-19) model presented body weight loss, high levels of respiratory viral RNA load, severe segmentary pneumonitis, and bronchial fistula besides lymphatic trapping and infiltration, like the human SARS-COV-2 pathogenesis. The presence of subepithelial lymphoeosinophilic infiltrate was highlighted in our results; it contributed to the detachment of SARS-CoV-2 nucleocapsid-positive epithelial cells resulting in the infectious cell plugs. MAIN CONCLUSIONS The SARS-CoV-2 caused segmentary pneumonia and vascular damage. In our comprehension, the infectious cell plugs, as being aspirated from the upper respiratory tract into the terminal bronchial lumen, work as a “Trojan horse”, thus contributing to the dissemination of the SARS-CoV-2 infection into specific regions of the deep lung parenchyma.

RESUMO Contexto: Nas últimas décadas, a ecoendoscopia evoluiu de uma ferramenta diagnóstica para uma plataforma para diversas intervenções terapêuticas. Vários avanços tecnológicos surgiram desde o último Consenso Brasileiro, demandando uma revisão e atualização das recomendações baseadas nas melhores evidências científicas. Métodos: Um grupo de 32 ecoendoscopistas renomados selecionou oito tópicos relevantes para serem discutidos a fim de gerar questões clínicas. Em seguida, foi realizada uma revisão da literatura para responder a essas perguntas com base nas evidências mais atualizadas. Resultados: Trinta e três tópicos foram formulados e votados pelos especialistas para alcançar um consenso. O Sistema de Oxford foi utilizado para classificar o nível de evidência. Conclusão: Há evidências moderadas para sustentar que a forma da agulha, calibre ou técnica de aspiração não influenciam no rendimento da amostragem tecidual guiada por ultrassom endoscópico (USE) de lesões sólidas pancreáticas. Há evidências moderadas para sustentar o uso da biópsia transcutânea guiada por USE da parede cística para diferenciar entre neoplasias císticas mucinosas e não mucinosas. Existem poucas evidências para apoiar o tratamento guiado por USE de varizes gástricas. Há um alto nível de evidência para sustentar que a drenagem biliar guiada por USE e a CPRE apresentam resultados semelhantes em pacientes com obstrução biliar maligna distal. Há um alto nível de evidência para o uso da USE no diagnóstico de cistos pancreáticos neoplásicos e na detecção de necrose antes de indicar a drenagem. Há evidências moderadas para sustentar a preferência pela gastroenterostomia guiada por USE em relação ao stent duodenal para obstrução maligna da saída gástrica em pacientes com expectativa de vida superior a 2 meses. Há um alto nível de evidência para sustentar o uso da ablação por radiofrequência no tratamento de ambos os tipos, funcionantes e não funcionantes, de tumores neuroendócrinos.

ABSTRACT Background: In the past decades, endoscopic ultrasound has developed from a diagnostic tool to a platform for many therapeutic interventions. Various technological advancements have emerged since the last Brazilian Consensus, demanding a review and update of the recommendations based on the best scientific evidence. Methods: A group of 32 renowned echoendoscopists selected eight relevant topics to be discussed to generate clinical questions. After that, a literature review was conducted to answer these questions based on the most updated evidence. Results: Thirty-three statements were formulated and voted on by the experts to reach a consensus. The Oxford System was used to grade the level of evidence. Conclusion: There is moderate evidence to support that the needle shape, gauge, or aspiration technique does not influence the yield of endoscopic ultrasound (EUS)-guided tissue sampling of pancreatic solid lesions. There is moderate evidence to support using EUS-TTNB of the cyst wall to differentiate between mucinous and non-mucinous cystic neoplasms. There is little evidence to support the EUS-guided treatment of gastric varices. There is a high level of evidence to support that EUS-guided biliary drainage and ERCP present similar outcomes in patients with distal malignant biliary obstruction. There is a high level of evidence for using EUS to diagnose neoplastic pancreatic cysts and detect necrosis before indicating drainage. There is moderate evidence to support EUS-GE over duodenal stent for malignant gastric outlet obstruction in patients with a life expectancy higher than 2 months. There is a high level of evidence to support the use of RFA in treating both functioning and non-functioning types of NET.

ABSTRACT Background: The intensity of dengue virus (DV) replication and circulating non-structural protein 1 (NS1) levels may promote changes in the human immune response and favor severe forms of infection. We investigated the correlations between NS1 with CXCL-8, CXCL-10, IFN-γ, and IL-12p40 serum levels, and IFN-γ receptor α chain (CD119) expression, and CXCL10 production by peripheral blood mononuclear cells (PBMCs) stimulated with recombinant IFN-γ in DV-infected patients with different clinical forms. Methods: Dengue virus NS1, CXCL-8, CXCL-10, IFN-γ, and IL-12p40 serum levels were measured in 152 DV-infected patients with different clinical forms and 20 non-infected individuals (NI) using enzyme-linked immunosorbent assay (ELISA). In addition, we investigated the CXCL-10 production after in vitro IFN-γ stimulation of PBMCs from 48 DV-infected individuals (with different clinical forms of dengue fever) and 20 NI individuals using ELISA, and CD119 expression on CD14+ cells with flow cytometry. Results: Patients with dengue hemorrhagic fever (DHF) had significantly higher NS1, CXCL-8, and CXCL-10 serum levels than those with classic dengue fever (DF). The response of PBMCs to IFN-γ stimulation was lower in patients with DHF than in those with DF or dengue with complications (DWC), with lower CD119 expression and reduced CXCL-10 synthesis. In addition, these alterations are associated with high NS1 serum levels. Conclusions: Patients with DHF reported high NS1 levels, low CD119 expression, and low CXCL-10 synthesis in PBMCs, which may be associated with infection progression and severity.

Resumo A nutrição na criação de coelhos representa cerca de 70% de todos os custos; nesse sentido, a Cratylia argentea é uma excelente alternativa como alimento devido à sua composição bromatológica. Nosso objetivo foi avaliar o valor nutricional de dietas formuladas com folhas secas de C. argentea na alimentação de coelhos em crescimento. Foram utilizados 28 coelhos brancos da raça Nova Zelândia, com 55 dias de idade, de ambos os sexos. Dois tratamentos (n = 14, 7 machos e 7 fêmeas) foram avaliados em delineamento experimental de blocos casualizados em esquema fatorial 2 x 2. A dieta controle (CTRL) foi formulada para atender às exigências nutricionais de coelhos em crescimento, e a dieta teste (DRY) foi obtida substituindo 20% da dieta CTRL por folhas secas de C. argentea. O período experimental compreendeu 11 dias, sendo sete dias de adaptação e quatro dias de coleta total de fezes. O ganho médio diário, o consumo de matéria seca, a conversão alimentar e o peso corporal final não foram afetados pela substituição da dieta CTRL por folhas secas de C. argentea. O coeficiente de digestibilidade da matéria seca apresentou melhores resultados nos coelhos CTRL (Fêmea: 72,19%, Macho: 72,48%). Coelhos alimentados com a dieta CTRL apresentaram maior consumo de proteína bruta do que os alimentados com a dieta DRY, porém esses coelhos tiveram maior excreção e menor retenção de proteína bruta. Conclui-se que Cratylia argentea apresenta valores de 1.400,67 kcal de energia digestível por kg de matéria seca e 3,34% de proteína digestível por kg de matéria seca. 70 custos sentido bromatológica C crescimento Zelândia 5 idade sexos n 14 fêmeas (CTRL DRY (DRY 20 1 fezes diário Fêmea (Fêmea 7219 72 19 72,19% Macho 72,48%. 7248 72,48% . 48 72,48%) Concluise Conclui se 140067 400 67 1.400,6 334 3 34 3,34 721 72,19 724 72,48 4 14006 40 6 1.400, 33 3,3 72,1 72,4 1400 1.400 3, 72, 140 1.40 1.4 1.

Abstract Nutrition in rabbit farming accounts for about 70% of all costs; in this sense, C. argentea is an excellent alternative as a feed, due to its bromatological composition. Our goal is to evaluate the nutritional value of diets formulated with the dried leaves of C. argentea to feed growing rabbits. Twenty-eight white rabbits of the New Zealand breed, 55 days old, of both sexes, were used. Two treatments (n = 14, 7 males, and 7 females) were evaluated in a randomized block experimental design in a 2 x 2 factorial scheme. The control diet (CTRL) was formulated to meet the nutritional requirements of growing rabbits, and the test diet (DRY) was obtained by replacing 20% of the CTRL diet with dried leaves of C. argentea. The experimental period was comprised of 11 days, with seven days of adaptation and four days of total feces collection. The average daily gain, dry matter intake, feed conversion, and final body weight were not affected by replacing the CTRL diet with the dried leaves of C. argentea. The coefficient of dry matter digestibility showed better results in CTRL rabbits (female: 72.19%, male: 72.48%). Rabbits fed with the CTRL diet exhibited a higher consumption of crude protein compared to those fed with the DRY diet, however, these rabbits showed higher elimination and lower retention of crude protein. It is concluded that C. argentea presents values of 1,400.67 kcal per kg of dry matter, digestible energy, and 3.34% digestible protein per kg of dry matter. 70 costs sense C composition Twentyeight Twenty eight breed 5 old sexes used n 14 males females scheme (CTRL (DRY 20 1 collection gain intake conversion female (female 7219 72 19 72.19% male 72.48%. 7248 72.48% . 48 72.48%) however 140067 400 67 1,400.6 energy 334 3 34 3.34 721 72.19 724 72.48 4 14006 40 6 1,400. 33 3.3 72.1 72.4 1400 1,400 3. 72. 140 1,40 1,4 1,

Abstract The effects of antibiotics on sperm longevity in collared peccary (Pecari tajacu) fresh diluted semen was evaluated. Semen samples from six adult males were collected by electroejaculation and diluted in Tris-citrate-fructose alone (control) and plus streptomycin-penicillin (2 mg/ml-2000 IU/ml) or gentamicin (70 µg/ml). Membrane integrity and functionality, mitochondrial activity and sperm morphology were assessed subjectively. Sperm motility and other kinetic parameters were objectively assessed using CASA (computer-assisted semen analysis). The semen diluted according to the treatments were submitted to the thermoresistance test, incubated at 37 ° C, and the sperm parameters analyzed at 0, 30, 60, 120 and 180 min. The average values of the treatments were compared with each other and between the times. There were no differences (P > 0.05) between treatments until the end of the test. Control and streptomycin-penicillin samples maintained sperm function for up to 180 min (with total motility of 24.3 ± 7.1% and 28 ± 8.7%, respectively). Gentamicin aliquots retained most parameters until the end of the incubation, except for membrane integrity and mitochondrial activity that declined (P < 0.05) at 180 min (53.1 ± 7.1% and 50.7 ± 6.2%, respectively) compared to 0 min (80.5 ± 4.7% and 86.3 ± 3.4%, respectively). In conclusion, a multiparametric thermoresistance test proved that Tris-based extenders used for collared peccary semen can be effectively supplemented by streptomycin-penicillin (2 mg/ml-2000 IU/ml) or gentamicin (70 µg/ml), especially during 180-min incubation at 37 °C.

ABSTRACT Objective To evaluate deaths, hospitalizations, and persistence of symptoms in patients with COVID-19 after infection in an outpatient setting during the first COVID-19 wave in Brazil. Methods This prospective cohort was between April 2020 and February 2021. Hospitalized or non-hospitalized COVID-19 patients until five days after symptom onset were included. The outcomes measured were incidence of death, hospitalization, and persistence of more than two symptoms 60 days after discharge. Results Out of 1,198 patients enrolled in the study, 66.7% were hospitalized. A total of 289 patients died (1 [0.3%] non-hospitalized and 288 [36%] hospitalized). At 60 days, patients non-hospitalized during admission had more persistent symptoms (16.2%) compared to hospitalized (37.1%). The COVID-19 severity variables associated with the persistence of two or more symptoms were increased age (OR= 1.03; p=0.015), respiratory rate at hospital admission (OR= 1.11; p=0.005), length of hospital stay of more than 60 days (OR= 12.24; p=0.026), and need for intensive care unit admission (OR= 2.04; p=0.038). Conclusion COVID-19 survivors who were older, tachypneic at admission, had a hospital length of stay >60 days, and were admitted to the intensive care unit had more persistent symptoms than patients who did not require hospitalization in the early COVID-19 waves.

Abstract We investigated the vasodilatory effects of Hymenaea rubriflora Ducke stem bark extract (HR- HAc). Vascular reactivity of the aortic rings of Wistar rats was tested by in vitro cumulative doses (0.1 - 729 μg/mL). Rats (n=5) were treated with 25 (G25), 50 (G50) and 100 (G100) mg/ kg of HR-HAc or saline (control group - CG) for four weeks. An in vitro assay resulted in dose-dependent relaxation of the aortic rings with functional endothelium, which was inhibited in the presence of L-NAME. Rings of the treated animals increased acetylcholine relaxing potency at all doses, with a greater effect on G50 (pD2 = 7.8±0.1, Emax = 95.6±1.1) and a decreased contractile potency to phenylephrine in G25 (pD2 = 6.9±0.06, Emax = 61.5±6.0%) and G50 (pD2= 6.6±0.06, Emax = 71.0±8.5%) when compared to the CG in the presence and absence of endothelium (pD2= 6.4± 0.1, 6.4±0.1 and 6.9±0.1, respectively). Cumulative doses of nitroprusside resulted in increased relaxing potency in all treated groups and maintained Emax at 100%. It is concluded that HR-HAc has vasorelaxant capacity and inhibitory vascular contraction activity applied either directly to aortic rings or after treatment with in vivo supplementation, which places this extract as a potential nutraceutical or pharmacological agent for treating diseases associated with vascular dysfunction.

Resumo O objetivo deste trabalho foi definir blocos experimentais para experimentos com cana-de-açúcar, com uso de técnicas de geoestatística, análise de componentes principais e técnicas de agrupamento aplicadas às propriedades do solo. Para isso, foram utilizados dados de propriedades químicas do solo de um experimento com cana-de-açúcar. As técnicas de geoestatística foram aplicadas para identificar a variabilidade espacial dessas propriedades e estimar os valores para locais não amostrados por meio de krigagem. A análise de componentes principais foi aplicada para redução dimensional, e, com as novas variáveis obtidas, realizou-se a análise de agrupamento pelo método k-means, para determinar os blocos experimentais com duas a cinco repetições. Das 12 variáveis analisadas, 10 apresentaram dependência espacial. A análise de componentes principais permitiu reduzir a dimensionalidade dos dados para duas variáveis, que explicaram 82,27% da variância total. Os blocos obtidos apresentaram formas poligonais irregulares, com diferentes formatos e tamanhos, e alguns mostraram descontinuidade.

Abstract The objective of this work was to define experimental blocks for sugarcane experiments using geostatistical techniques, principal component analysis, and clustering techniques applied to soil properties. For this, data of soil chemical properties from a sugarcane experiment were used. Geostatistical techniques were applied to identify the spatial variability of these properties and to estimate the values for non-sampled locations through kriging. The principal components analysis was used for dimensional reduction, and, with the new variables obtained, the cluster analysis was performed using the k-means method to determine the experimental blocks with two to five replicates. Of the 12 analyzed variables, 10 showed spatial dependence. The principal component analysis allowed reducing the dimensionality of the data to two variables, which explained 82.27% of total variance. The obtained blocks presented irregular polygonal shapes, with different formats and sizes, and some of them showed discontinuities. The proposed methodology has the potential to identify more uniform areas in terms of soil chemical properties to allocate experimental blocks for sugarcane. nonsampled non sampled kriging reduction kmeans k means replicates 1 dependence 8227 82 27 82.27 variance shapes sizes discontinuities 822 8 2 82.2 82.
