Abstract Batesian mimicry may result in remarkable cases of phenotypic convergence that represent classic examples of evolution through natural selection. The existence of mimicry systems among coral snakes, however, remains controversial because of contradictions between the predictions of mimetic theory and the empirical patterns of co-occurrence and species abundance. Here, we analyze the geographic distribution of coral snake species of the genus Micrurus and populations of the false coral snake Atractus latifrons in Amazonia, and perform ecological niche modeling (ENM) analyzes to generate potential geographic distributions of species of Micrurus and A. latifrons, identify patterns of co-occurrence and assess whether the distribution of A. latifrons coincides with the distribution of Micrurus species, which could suggest the existence of a possible mimetic relationship between the species. We identified six Micrurus species that may represent mimetic models for A. latifrons. The results of the co-occurrence analysis corroborates the results from ENM, indicating that chromatic patterns of A. latifrons and their respective model species are aggregated. Our study suggests that all color patterns of A. latifrons – including the tricolor monads, and the more common tricolor dyads and tricolor tetrads – may benefit from the resemblance with other Micrurus species as perfect and imperfect mimics.

RESUMO Objetivos: mapear as prescrições de enfermagem para pacientes com diagnósticos relacionados à hipotermia no período intraoperatório com as atividades propostas pela Classificação das Intervenções de Enfermagem e caracterizar a amostra a partir dos fatores de risco para o desenvolvimento desse desconforto. Método: estudo descritivo, do tipo documental, retrospectivo, com abordagem quantitativa, que seguiu três etapas: catalogação das intervenções, análise documental e mapeamento cruzado. Foram avaliadas as variáveis: idade e sexo do paciente; tempo de cirurgia; temperaturas mínima, média, máxima e variação da temperatura da sala de operação e do paciente; e tipo de cirurgia envolvendo abertura de cavidade corporal ou não, em uma amostra de 138 prontuários avaliados de agosto a setembro de 2019 através da utilização de um checklist composto por dados de identificação e componentes dos diagnósticos NANDA-International: risco de hipotermia perioperatória e hipotermia. Empregou-se análises de frequências absoluta e percentual, média, desvio padrão e software R. Resultados: verificou-se 419 atividades inseridas em 12 intervenções relacionadas à hipotermia na taxonomia correspondente; 13 cuidados de enfermagem prescritos e cinco intervenções mapeadas. Das variáveis, obtiveram significância o tempo da cirurgia e abertura da cavidade. Conclusão: por meio do mapeamento cruzado, pode se afirmar que os cuidados prescritos são embasados na linguagem padronizada contribuindo para a unificação da prática da enfermagem.

ABSTRACT Objectives: to map the Nursing prescriptions for patients with diagnoses related to hypothermia in the intraoperative period with the activities proposed by the Nursing Interventions Classification, and to characterize the sample based on the risk factors for the development of this discomfort. Method: a descriptive, documentary and retrospective study, with a quantitative approach that followed three stages: cataloging of the interventions, documentary analysis, and cross-mapping. The following variables were analyzed: patient's age and gender; surgery duration; minimum, mean and maximum temperatures, and variation of the surgery room and patient temperatures; and whether or not the type of surgery involved opening a body cavity, in a sample of 138 medical charts evaluated from August to September 2019 by using a checklist composed of identification data and diagnosis components from the NANDA-International diagnoses: risk of perioperative hypothermia and hypothermia. Absolute and percentage frequency analyses, mean, standard deviation, and the R software were employed. Results: 419 activities incorporated in 12 interventions were verified that were related to hypothermia in the corresponding taxonomy; as well as 13 Nursing care measures prescribed and five interventions mapped. The variables which reached significance were surgery duration and cavity opening. Conclusion: by means of cross-mapping, it can be asserted that the care measures prescribed are based on the standardized language, thus contributing to unification of the Nursing practice.

RESUMO: Esse estudo descreve um surto de hepatopatia necrótica aguda associada a intoxicação espontânea por Lantana camara L. em bovinos leiteiros. Um lote de 15 vacas e novilhas foram introduzidas em um piquete com campo nativo, com escassa oferta de alimento. Após dezesseis dias, oito animais manifestaram epistaxe, febre, apatia, icterícia, fezes ressecadas e escuras com muco e sangue. A evolução do quadro clínico variou de dois a cinco dias. No piquete em que os bovinos estavam alojados havia grande quantidade de L. camara L. com sinais evidentes de consumo. No total, sete bovinos morreram, e destes, o exame post mortem foi realizado em três. Os bovinos exibiam moderada icterícia, hemorragias no tecido subcutâneo e na superfície de diferentes órgãos. O fígado estava discretamente aumentado, com coloração alaranjada e padrão lobular evidente. As lesões histológicas consistiam em acentuada necrose de coagulação de hepatócitos em região centrolobular, por vezes se estendendo a região mediozonal, além de acentuada degeneração dos hepatócitos e evidente Colestase. O presente trabalho alerta para que intoxicação por L. camara L. seja levada em consideração nos diagnósticos diferenciais de hepatotoxicidade necrótica aguda em bovinos, mesmo sem indícios de fotossensibilização.

ABSTRACT: This study describes an outbreak of acute necrotic hepatopathy associated with spontaneous poisoning by Lantana camara L. in dairy cattle. A herd of 15 cows and heifers was introduced into a native pasture with limited food supply, and, sixteen days later, eight animals had spontaneous nasal hemorrhage, fever, lethargy, jaundice, and dry, dark stools with mucus and blood. The clinical course varied from two to five days. In the pasture where the cattle were kept, abundant adult specimens of L. camara L. with evident signs of consumption were observed. In total, seven cattle died and necropsy was performed in three of them. All animals had moderate jaundice, hemorrhage in the subcutaneous tissue and on the surface of different organs. The liver was slightly enlarged, with orange discoloration and enhanced lobular pattern. Histologically, multifocal areas of coagulative necrosis of hepatocytes in the centrilobular area, occasionally extending to the midzonal area, were observed, as well as marked hepatocellular degeneration and prominent cholestasis. The current study suggests that L. camara L. poisoning should be considered a differential diagnosis of acute and necrotic hepatotoxicity in cattle, despite the absence of photosensitization.

RESUMO: Brasil é o quarto maior exportador de carne suína do mundo, com sua produção concentrada na região Sul do país. Para reduzir os impactos econômicos e aumentar a saúde do rebanho, é necessário o diagnóstico eficiente das doenças. A frequência, distribuição sazonal e anual das doenças que afetam o sistema nervoso de suínos no Sul do Brasil foram determinadas através de um estudo retrospectivo no período de 2008 a 2018. Foram avaliados 231 suínos, distribuídos nas seguintes fases: maternidade, creche, crescimento, terminação e adultos. Leitões da fase de creche foram os mais afetados com 58,01%. As doenças de origem infecciosa foram responsáveis por 87,01% (201/231) das causas de lesões no sistema nervoso. Meningite bacteriana foi observada em 58,87% dos casos, apresentando distribuição endêmica, e uma tendência a ocorrer nos meses de outono/inverno. O maior número de casos de circovírus suíno foram observados em 2008 e 2009, com declínio posterior. Circovírus suíno, intoxicação por sal e os abscessos encefálicos não apresentaram associação entre a ocorrência sazonal e distribuição anual. A intoxicação por sal foi observada com maior frequência nos últimos anos deste estudo. A encefalomielite não supurativa e a intoxicação por selênio exibiram associação entre a sua ocorrência e distribuição sazonal, nos meses de inverno e verão, respectivamente.

ABSTRACT: Brazil is the fourth largest exporter of pork worldwide, with its production concentrated in the Southern region of the country. To reduce the economic impacts and increase herd health, an efficient diagnosis of diseases is necessary. The frequency, seasonal, and annual distribution of diseases that affecting the swine nervous system in Southern Brazil were determined through a retrospective study conducted from 2008 to 2018. A total of 231 pigs were evaluated, and distributed in the following phases: suckling piglets, nursery, growing, finishing, and adults. Piglets in the nursery phase were the most affected with 58.01%. Infectious diseases accounted for 87.01% (201/231) of lesions in the nervous system. Bacterial meningitis was observed in 58.87% of cases, presenting an endemic distribution, and a propensity to occur in the months of autumn/winter. The highest number of cases of porcine circovirus-2 were observed in 2008 and 2009, with a subsequent decline. Porcine circovirus, salt poisoning, and brain abscesses exhibited no association between the seasonal occurrence and annual distribution. Salt poisoning was observed more frequently in the last years of this study. Both, non-suppurative encephalomyelitis and selenium toxicosis exhibited an association between their occurrence and seasonal distribution in, the months of winter, and summer, respectively.

In this work, bio-oil (an organic matrix rich in oxygen functionalities) was used to efficiently dissolve and disperse Fe3+ which upon thermal treatment produced a carbon containing dispersed and encapsulated Fe oxide magnetic nanoparticles. These materials were prepared by dissolution of 8, 16 and 24 wt.% Fe3+ salt in bio-oil followed by treatment at 400, 450, 500 or 600 ºC in N2 atmosphere. X-ray diffraction (XRD), scanning (SEM) and transmission electron microscopies (TEM), elemental analysis, thermogravimetric-mass spectrometry (TG-MS), potentiometric titration, Raman and Mössbauer spectroscopies showed that Fe3+ species in bio-oil is reduced to produce magnetic nanoparticles phases: magnetite Fe3O4 and maghemite γ-Fe2O3. At low temperatures, the iron phases were less protected, and the carbon matrix was more reactive, while in temperatures above 500 ºC, the iron phases were more stable, however, the carbon matrix was less reactive. Reaction of these magnetic carbon materials with concentrated H2SO4 produced surface sulfonic acidic sites (ca. 1 mmol g-1), especially for the materials obtained at 400 and 450 ºC. The materials were used as catalysts on esterification reaction of oleic acid with methanol at 100 ºC and conversions of 90% were reached, however, after 2 consecutive uses, the conversion decreased to 30%, being required more studies to improve the material stability.

Abstract Our objective was to quantify the relationship between seasons of the year, milk production, and milk composition of a dairy farm based on data for 48 consecutive months, using multivariate statistical analyses. The dataset contained information on productive indexes and milk composition from the bulk tank milk, which was measured from milk samples, collected monthly and used to determine the total dry extract and defatted dry extract, lactose, fat, protein, somatic cell count, and total bacterial count. Seasons of the year and milk production/hectare were also considered. Factor, cluster, and discriminant analysis were used to study the relationships between the above-mentioned variables. A positive relationship was noted between season and total dry extract, defatted dry extract, milk fat, and protein, with higher values being observed in winter and spring. Similarly, a positive relationship was noted between season and milk production/hectare, lactose content, with an increase in milk production and lactose content in winter and spring, which was negatively related to the somatic cell count and total bacterial count. Milk production and composition varied mainly with seasons. Multivariate analyses facilitated a better understanding of the relationship between milk production and composition on this dairy farm.

Abstract Amazon parrots are long-lived birds with highly developed cognitive skills, including vocal learning. Several parrot mitogenomes have been sequenced, but important aspects of their organization and evolution are not fully understood or have limited experimental support. The main aim of the present study was to describe the mitogenome of the blue-fronted Amazon, Amazona aestiva, and compare it to other mitogenomes from the genus Amazona and the order Psittaciformes. We observed that mitogenomes are highly conserved among Amazon parrots, and a detailed analysis of their duplicated control regions revealed conserved blocks. Population level analyses indicated that the specimen analyzed here seems to be close to A. aestiva individuals from Bahia state. Evolutionary relationships of 41 Psittaciformes species and three outgroups were inferred by BEAST. All relationships were retrieved with high support.

Abstract The reward sensation after food intake may be different between individuals and variants in genes related to the dopaminergic system may indicate a different response in people exposed to the same environmental factors. This study investigated the association of TaqIA (rs1800497) and -141C InsDel (rs1799732) variants in DRD2/ANKK1 gene with food intake and adiposity parameters in a cohort of children. The sample consisted of 270 children followed until 7 to 8 years old. DNA was extracted from blood and polymorphisms were detected by PCR-RFLP analysis. Food intake and nutritional status were compared among individuals with different SNP genotypes. Children carrying the A1 allele (TaqIA) had higher energy of lipid dense foods (LDF) when compared with A2/A2 homozygous children at 7 to 8 years old (GLM p=0.004; Mann Whitney p=0.005). No association was detected with -141C Ins/Del polymorphism. To our knowledge, this is the first association study of the DRD2 TaqIA and -141C Ins/Del polymorphism with food intake and anthropometric parameters in children. DRD2 TaqIA polymorphism has been associated with a reduction in D2 dopamine receptor availability. Therefore, the differences observed in LDF intake in our sample may occur as an effort to compensate the hypodopaminergic functioning.

ABSTRACT To increase the availability to consumers and add more value to persimmon (Diospyros kaki L.), which is a very perishable and seasonal fruit and in order to identify which cultivars grown in subtropical regions are more suitable for processing in the form of juice and jelly, as well as understand what the consumer profile is for these products, the objective of this study was to evaluate the influence of different persimmon cultivars (Rama Forte, Mel, Guiombo and Taubaté) grown in subtropical regions of Brazil on the physicochemical characteristics, rheological properties and sensory acceptance of the resulting juice and jelly in order to identify cultivars with the greatest potential for industrial use. The different studied persimmon cultivars had different physical and physicochemical characteristics which resulted in juices and jellies with different physicochemical, rheological and sensory characteristics. Based on sensory acceptance and productivity/adaptability of persimmon crop in Brazil, the most suitable persimmon cultivars for processing are Rama Forte and Guiombo. In this study it was found that the consumer prefers a more acidic persimmon juice and a less firm or softer, less sweet, clearer and more intense yellow color persimmon jelly.

Abstract Taste perception plays a key role in determining individual food preferences and dietary habits and may influence nutritional status. This study aimed to investigate the association of TAS1R2 (Ile191Val - rs35874116) and TAS1R3 (-1266 C/T - rs35744813) variants with food intake and nutritional status in children followed from birth until 7.7 years old. The nutritional status and food intake data of 312 children were collected at three developmental stages (1, 3.9 and 7.7 years old). DNA was extracted from blood samples and the polymorphisms were analyzed by real-time polymerase chain reactions (qPCR) using hydrolysis probes as the detection method. Food intake and nutritional status were compared among individuals with different single nucleotide polymorphism (SNP) genotypes. At 3.9 years old, children homozygous (Val/Val) for the TAS1R2 Ile191Val polymorphism ingested less sugar and sugar-dense foods than children who were *Ile carriers. This finding demonstrated that a genetic variant of the T1R2 taste receptor is associated with the intake of different amounts of high sugar-content foods in childhood. This association may provide new perspectives for studying dietary patterns and nutritional status in childhood.

Resumo Fungos filamentosos são organismos amplamente diversificados e ubíquos. Esta biodiversidade ainda é pouco caracterizada, desta forma, há um grande potencial a ser descoberto, sobretudo em biomas tropicais, que favorecem o crescimento e diversificação de espécies. Fungos filamentosos são extensivamente utilizados para a produção industrial de enzimas, como as amilases. Esta classe de enzimas atua na hidrólise do amido em glicose ou maltooligossacarídeos. Neste trabalho 25 cepas de fungos filamentosos foram isoladas a partir de amostras de material em decomposição coletados na Mata Atlântica Brasileira. As duas cepas que produziram mais amilases foram identificadas como Aspergillus brasiliensis e Rhizopus oryzae. Ambos os fungos são mesofílicos, crescem bem em meio de cultivo rico em nitrogênio orgânico, e produziram grande quantidade de glucoamilase. As enzimas de A. brasiliensis e R. oryzae possuem características distintas, possivelmente devido à distância filogenética das espécies. A produção de amilase mais expressiva de A. brasiliensis ocorreu em 120 horas de cultivo e pH inicial de 7,5; possui maior atividade em temperaturas entre 60-75ºC e pH entre 3,5-5,0. Ambas glucoamilases fúngicas obtiveram ampla estabilidade de pH (3-8) e foram ativadas por Mn2+. A melhor produção de R. oryzae ocorreu em 96 horas de cultivo e pH 6,5. Suas amilases são mais ativas na faixa de pH de 4,0-5,5 e temperatura entre 50-60ºC. A diferença mais significativa dentre as enzimas produzidas pelos fungos selecionados é a resistência à desnaturação térmica, tendo a glucoamilase de A. brasiliensis um T50 de 60 minutos a 70ºC, já a glucoamilase de R. oryzae somente obteve atividade residual quando incubada a 50°C, com um T50 de apenas 12 minutos.

Abstract Filamentous fungi are widely diverse and ubiquitous organisms. Such biodiversity is barely known, making room for a great potential still to be discovered, especially in tropical environments - which are favorable to growth and species variety. Filamentous fungi are extensively applied to the production of industrial enzymes, such as the amylases. This class of enzymes acts in the hydrolysis of starch to glucose or maltooligosaccharides. In this work twenty-five filamentous fungi were isolated from samples of decomposing material collected in the Brazilian Atlantic Forest. The two best amylase producers were identified as Aspergillus brasiliensis and Rhizopus oryzae. Both are mesophilic, they grow well in organic nitrogen-rich media produce great amounts of glucoamylases. The enzymes of A. brasiliensis and R. oryzae are different, possibly because of their phylogenetical distance. The best amylase production of A. brasiliensis occurred during 120 hours with initial pH of 7.5; it had a better activity in the pH range of 3.5-5.0 and at 60-75°C. Both fungal glucoamylase had wide pH stability (3-8) and were activated by Mn2+. R. oryzae best production occurred in 96 hours and at pH 6.5. Its amylases had a greater activity in the pH range of 4.0-5.5 and temperature at 50-65ºC. The most significant difference between the enzymes produced by both fungi is the resistance to thermal denaturation: A. brasiliensis glucoamylase had a T50 of 60 minutes at 70ºC. The R. oryzae glucoamylase only had a residual activity when incubated at 50°C with a 12 min T50.

RESUMO INTRODUÇÃO: A doença pulmonar crônica (DPC), conhecida clinicamente como displasia broncopulmonar, é uma das maiores causas de morbidade em neonatos que nasceram prematuros e foram submetidos à oxigenioterapia. OBJETIVO: Identificar moléculas inflamatórias em tecido pulmonar de recém-nascidos prematuros que morreram com DPC por meio do método de imuno-histoquímica. MÉTODOS: Análise imuno-histoquímica de 51 amostras de pulmões de recém-nascidos prematuros – formando os grupos: sem DPC, DPC"nova" e DPC"clássica". RESULTADOS: O influxo de neutrófilos e o número de células CD4+ e CD45RO+ foram maiores no grupo DPC"clássica" (p < 0,001). CONCLUSÃO: Os resultados sugerem que o processo inflamatório é mediado por neutrófilos e linfócitos CD45RO+ e CD4+ na DPC"clássica".

ABSTRACT INTRODUCTION: Chronic lung disease (CLD), clinically known as bronchopulmonary dysplasia (BPD), is a major cause of morbidity in premature newborn and were submitted to oxygen therapy. OBJECTIVE: Immunohistochemical identification of inflammatory molecules in the lung tissue of premature neonates that died with CLD. METHODS: Immunohistochemical analysis of 51 samples of premature newborn lungs – grouped in: without CLD,"classic" CLD and"new" CLD. RESULTS: Neutrophil influx and the number of CD4+ and CD45RO+ cells were higher in the"classic" CLD group (p < 0.001). CONCLUSION: Our findings suggest that the inflammatory response is mediated by neutrophils and CD45RO+ and CD4+ T lymphocytes in the"classic" CLD.
