Characterizing their protein content and quality, including in underutilized grain legumes, e.g., grass pea, gives value to the legumes’ underexplored variability. To fill the gap of knowledge in legumes’ protein quality, for the first time, five extensive collections of cool season grain legumes were cropped under the same environmental conditions and further analyzed. Multivariate analysis showed the existent intra- and inter-species variability. The legume species with the highest protein content, grass pea, Lathyrus sativus (LS), was not the one with the overall highest individual amino acids content and in vitro protein digestibility. With these last characteristics lentil, Lens culinaris (LC), was highlighted. The highest average values of arginine (Arg), glutamic acid (Glu), and threonine (Thr) were found in LS and Vicia faba (VF). Cicer arietinum (CA) stood out as the species with the highest values of Thr and methionine (Met). Regarding the in vitro protein digestibility (IVPD), LC, followed by Pisum sativum (PS) and LS, were the legume species with the highest values. Ultimately, this study bought to the fore legume species that are not commonly used in western diets but have high adaptability to the European agricultural systems.publishersversionpublishe

Caracterização fisiológica de Bipolaris bicolor advindos de sementes de trigo

O objetivo deste trabalho foi avaliar o crescimento micelial in vitro de isolados de Bipolaris bicolor e analisar a produção in vitro de conídios de B. bicolor em diferentes regimes de luz (0 hora, 12 horas e 24 horas) a uma temperatura de 25ºC. Os isolados utilizados para a realização deste trabalho fazem parte da Coleção de fungos fitopatogênicos do Laboratório de Fitopatologia da UEG, Unidade de Ipameri. Os mesmos foram reativados para a realização deste experimento, em meio BDA (Agar Batata Dextrose). Foram avaliados o crescimento micelial, através de discos de micélio que foram avaliados diariamente até o quinto dia após a inoculação (DAI) e para a esporulação, após a última leitura do crescimento radial, as placas foram aproveitadas para quantificação de produção de esporos de B. bicolor. O delineamento experimental utilizado foi o inteiramente casualizado (DIC), com cinco repetições para cada tratamento e os dados foram submetidos à análise de variância e ao teste Scott-Knott (P≤0,05), com o auxílio do software Sisvar 5.6. O crescimento micelial dos diferentes isolados de B. bicolor foi indiferente quanto aos regimes de luz e a produção de conídios de B. bicolor foi superior nos regimes de luz de 12 e 24 h

Performance, nutrient digestibility, and muscular evaluation of female broiler chickens fed different dietary protein levels and slaughtered at 38 or 46 days

ABSTRACT This study evaluated the effects of two protein levels and types of formulation on performance, nutrient metabolization, and myopathies of 390 female broilers from 21 to 46 days old distributed in a completely randomized design, with five treatments and six replicates of 13 broilers each. Treatments were two levels of protein (19.0 and 21.0%) in diets using only commercially available ingredients and three experimental formulations designed to keep similar the main nutrients that could influence nutritional performance (starch, fiber, ether extract), using unusual ingredients, with 19.0% (19E) or 21.0% (21E) crude protein and the third with 19.0% crude protein with amino acid levels similar to treatment 21P (19E+Aa). We studied broiler performance, nutrient digestibility, macroscopic muscular evaluation, and histological muscular evaluation. The design for the performance and myopathy assessment was a 5 × 2 factorial scheme, five diets × two ages (38 or 46 days). The worst feed conversion ratio was observed for the 19P treatment. Neither diet nor age had an effect on myopathies, however, older slaughter age increased the intensity of microscopic lesions. The diet 19P should be avoided and increased inclusion of lipids in diets improves nutrient utilization and, consequently, performance

Eggshell microbiology and quality of hatching eggs subjected to different sanitizing procedures

O objetivo deste trabalho foi avaliar o efeito de diferentes procedimentos de desinfecção alternativos à fumigação com formaldeído sobre a redução da contagem microbiana e a qualidade de casca de ovos de matrizes Cobb de 42 semanas de idade. Um total de 10.080 ovos limpos coletados dos ninhos foi distribuído de maneira aleatória, em delineamento de blocos ao acaso, entre os seguintes tratamentos: fumigação com 13,33 g m-3 de paraformaldeído, fumigação com 5–10 ppm de ozônio, 6,36 mW cm-2 de irradiação de luz UV-C, pulverização com 1,56% de peróxido de hidrogênio, pulverização com 0,13% de ácido peracético, pulverização com água (controle úmido) e sem desinfecção (controle seco). Por tratamento, foram coletadas oito amostras de quatro ovos cada uma, momentos antes e após as desinfecções, para contagem de Enterobacteriaceae e bactérias mesófilas aeróbicas totais da casca. Somente os ovos submetidos aos tratamentos com formaldeído e UV apresentaram redução significativa nas contagens de bactérias mesófilas aeróbicas totais, quando comparados aos do grupo controle seco. Os tratamentos não influenciaram a espessura e a resistência da casca. A exposição de luz UV é eficaz em reduzir a contagem microbiana da casca de ovos de matrizes de 42 semanas de idade, sem afetar sua qualidade, e pode ser considerada alternativa ao uso de formaldeído para desinfecção.The objective of this work was to evaluate the effect of different disinfection procedures as alternatives to formaldehyde fumigation on eggshell microbial load and quality of eggs from a 42-week-old Cobb commercial breeder flock. A total of 10,080 clean eggs collected from the nests were randomly distributed in a randomized complete block design, among the following treatment groups: 13.33 g m-3 formaldehyde fumigation, 5–10 ppm ozone fumigation, 6.36 mW cm-2 UV-C light irradiation, spraying with 1.56% hydrogen peroxide, spraying with 0.13% peracetic acid, spraying with water (wet control), and no disinfection procedure (dry control). Per treatment, eight samples of four eggs each were collected before and after the disinfection procedure, in order to count the number of Enterobacteriaceae and total aerobic mesophilic bacteria on the eggshell. Only eggs subjected to the formaldehyde and UV treatments showed a significant reduction in total aerobic mesophilic bacterial count on the eggshell, when compared with those of the dry control group. Treatments did not affect eggshell thickness and resistance force. UV light exposure is effective in reducing microbial load on 42-week-old breeder flock eggshells, without affecting their quality, and can be considered an alternative to formaldehyde disinfection

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Anomalia de Ebstein com comunicação interatrial em paciente gestante com pré-eclâmpsia: um raro relato de caso

A Anomalia de Ebstein (AE) é uma cardiopatia congênita rara, ocorre em apenas 1% das más formações cardíacas. É uma alteração da implantação dos folhetos da valva tricúspide, ocorre o aumento do volume do átrio direito e a atrialização do ventrículo direito. Geralmente, possui uma evolução clínica lenta, com sintomas aparecendo em idade avançada. A comunicação interatrial (CIA), também consiste em uma cardiopatia congênita, do tipo acianótica, comumente assintomática, com prevalência de 5 a 10% de todas as cardiopatias, mais comum em mulheres. Baseia-se na formação de um “shunt” esquerdo-direito, podendo causar hiperfluxo da veia pulmonar. Por outro lado, a pré-eclâmpsia é uma complicação gestacional detectada na vigésima semana. É uma disfunção materno/placentária responsável por elevação da pressão arterial (> 140/90 mmHg), associada a lesão de órgão alvo, proteinúria ou disfunção útero/placentária. Neste estudo, o objetivo é relatar as complicações desenvolvidas durante a gestação em paciente que possuía essa rara associação de comorbidades. Paciente feminina, 20 anos, primigesta com 30 semanas e 4 dias, vista em USG obstétrico, com descontrole pressórico desde de o início da gestação. Cardiopata, sem acompanhamento, apresentando EA e IA (diagnóstico em laudo de 2008). Foi admitida em Unidade de Terapia Intensiva (UTI) com dispneia, saturação de O2 de 91%, pressão de 150/100 mmHg. Após estabilização, solicitados pareceres para cardiologia, obstetrícia e risco anestésico. USG obstétrico mostrou compartimento fetal alterado e relação cérebro/placentária alterada. No 2º dia, após corticoterapia, paciente retorna do centro-cirúrgico após cesariana, acoplada à ventilação mecânica invasiva, devido à descompensação. Radiografia pós-cirurgia mostrou pequeno derrame pleural bilateral. Mantida Cefalotina por mais 2 dias. No dia 3, TC de tórax revelou derrame persistente e consolidações, iniciando Ceftriaxone e Clindamicina. Noradrenalina iniciada após descompensação hemodinâmica. No dia 6, após teste de respiração espontânea bem-sucedido, o ecocardiograma evidenciou AE, insuficiência tricúspide acentuada e mitral leve. Sem critérios graves, a paciente foi transferida para a enfermaria para seguimento e término da antibioticoterapia. A gestação pode agravar riscos em pacientes com comorbidades raras como anomalias cardíacas congênitas. O acompanhamento específico é crucial e, em casos graves, a gravidez deve ser evitada

Elective cancer surgery in COVID-19-free surgical pathways during the SARS-CoV-2 pandemic: An international, multicenter, comparative cohort study

PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19–free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19–free surgical pathways. Patients who underwent surgery within COVID-19–free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19–free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score–matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19–free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19–free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks
