ABSTRACT Recent studies have evidenced exogenous enzymes as nutritional tool to elaborate low-polluting aquafeeds. This study aimed to evaluate effects of enzyme complex (EC) on apparent digestibility coefficients (ADC) of energy and nutrients, including amino acids, as well nitrogen (N) and phosphorus (P) loss in pre-growout Nile tilapia (Oreochromis niloticus). Diets without EC (Control) or with EC supplemented at 225 (EC225) or 450 mg/kg diet (EC450) and fed to Nile tilapia (n = 135, 150 ± 20 g) distributed in an entirely randomized design of three treatments and three replicates of 15 fish each. Fish fed diet EC450 showed higher digestibility of energy, protein, amino acids and mineral, and increased digestible energy (DE; +221.25 kcal/kg diet), digestible protein (DP; +10.54 g/kg diet) contents of diets, whereas reduced N (−23.82%) and P (−18.46%) loss relative to fish fed diet control. This study evidenced that EC at 450 mg/kg diet optimizes the ADC of multiple nutrients, including amino acids, and identified its potential to enhance the nutritive value of feeds and elaborate sustainable feeds for Nile tilapia.

RESUMO Estudos recentes têm evidenciado enzimas exógenas como ferramenta nutricional para elaboração de dietas aquáticas pouco poluentes. Este estudo teve como objetivo avaliar os efeitos de um complexo enzimático (CE) nos coeficientes de digestibilidade aparente (CDA) de energia e nutrientes, incluindo aminoácidos, bem como perda de nitrogênio (N) e fósforo (P) em tilápia-do-nilo, Oreochromis niloticus em crescimento. Dietas sem CE (Controle) ou com EC suplementado em 225 (CE225) ou 450 mg/kg dieta (CE450) foram fornecidas para tilápias do Nilo (n = 135, 150 ± 20 g) distribuídas em um desenho inteiramente aleatório de três tratamentos e três repetições de 15 peixes cada. Peixes alimentados com a dieta EC450 apresentaram maior digestibilidade da energia, proteína, aminoácidos e minerais, e aumento nos conteúdos de energia digestível (ED; +221,25 kcal/kg dieta) e proteína digestível (PD; +10,54 g/kg dieta) das dietas, enquanto houve redução na perda de N (−23,82%) e P (−18,46%) em relação aos peixes alimentados com a dieta de controle. Este estudo evidenciou que o CE a 450 mg/kg de dieta otimiza o CDA de múltiplos nutrientes, incluindo aminoácidos e identificou seu potencial para melhorar o valor nutritivo dos alimentos, assim como elaborar dietas sustentáveis para tilápias do Nilo.

ABSTRACT Introduction: Chikungunya chronic joint disease causes debilitating arthralgia, significantly impacting the quality of life of affected individuals. Methods: In this study, patients underwent clinical follow-ups, joint biopsies, and pre-biopsy and 24 months post-biopsy serum dosage of cytokines. Results: All participants were female and had pain in 12 joints on average, with 41.17% exhibiting moderate disease activity. Histopathological analysis revealed collagen deposition. Indirect immunofluorescence detected the CHIKV glycoprotein E1 antigen, and an increase in cytokines. Conclusions: Persistent inflammation and ineffective antiviral immune responses leading to antigen persistence may contribute to chronic CHIKV arthritis.

Abstract The objective of this work was to evaluate the physiological, phenotypic, and gene expression parameters in genetically modified (GM) rice plants that overexpress the Oryza sativa Vacuolar H+-Pyrophosphatase 1 (OVP1) gene, compared with non-genetically modified (NGM) rice. GM and NGM plants of the BRSMG Curinga cultivar were evaluated in two experiments, in a laboratory and greenhouse, in a randomized complete block design, with four replicates. Agronomic traits of interest were estimated, and transcriptome analysis and gene expression quantification were carried out. GM plants showed a 31 and 21% higher number of spikelets per panicle and total number of grains per panicle, respectively, in comparison with NGM plants. Physiological changes occurred during the grain-filling stage, in which GM plants presented a photosynthetic rate and carboxylation efficiency 61 and 89% higher than those of NGM plants, respectively. The overexpression of the OVP1 gene favors the upregulation of some photosynthesis genes and the increase in the number of spikelets and in the photosynthetic rate, but does not favor the increase in grain yield.

Resumo O objetivo deste trabalho foi avaliar os parâmetros fisiológicos, fenotípicos e de expressão gênica em plantas de arroz geneticamente modificadas (GM) que superexpressam o gene Oryza sativa Vacuolar H+-Pyrophosphatase 1 (OVP1), em comparação ao arroz não geneticamente modificado (NGM). Plantas GM e NGM da cultivar BRSMG Curinga foram avaliadas em dois experimentos, em laboratório e casa de vegetação, no delineamento de blocos ao acaso, com quatro repetições. Foram estimados caracteres agronômicos de interesse, e realizadas análise de transcritoma e quantificação da expressão gênica. Plantas GM apresentaram número de espiguetas por panícula e número total de grãos por panícula 31 e 21% maiores, respectivamente, em comparação às plantas NGM. Ocorreram alterações fisiológicas durante a fase de enchimento de grãos, em que as plantas GM apresentaram taxa fotossintética e eficiência de carboxilação 61 e 89% mais altas do que as das plantas NGM, respectivamente. A superexpressão do gene OVP1 favorece a indução de alguns genes da fotossíntese e o aumento do número de espiguetas e da taxa fotossintética, mas não favorece o aumento da produtividade de grãos.

Résumé Cette étude a analysé la relation entre le travail et la santé de personnes qui ont exercé leur activité dans des services de santé face au COVID-19. Elle a compté avec la participation de 108 professionnels travaillant dans l’Etat de Paraíba - Brésil. Un questionnaire a été utilisé, afin de caractériser les états de santé, l’organisation et les conditions de travail, l'accès à la formation et la disponibilité des équipements de protection individuelle (EPI). Les données recueillies, analysées à l’aide du référentiel de la clinique de l'activité, soulignent qu'il y avait peu d'offre de formation et d’exercices pratiques permettant de mieux agir face à la pandémie. Par ailleurs, ces professionnels disent avoir vécu des conditions et des organisations du travail qui n'ont pas intégré les questions de leur santé mentale. Ont été également mentionnés : peu de reconnaissance sociale, de faibles rémunérations, ainsi que les effets négatifs, sur le plan de leur activité de travail, de problèmes de gestion publique et des établissements de santé.

Abstract This study analyzed the relationship between work and health of COVID-19 frontline healthcare workers. 108 professionals from the state of Paraíba participated through a questionnaire aimed at characterizing the health, organization and working conditions, and the access to training and Personal Protective Equipment (PPE) of these professionals. The results, analyzed through the lens of the Activity Clinic, indicate that the workers experienced unsatisfactory working conditions and a work organization that did not prioritize mental health nor offered enough courses and training to act with COVID-19. In addition, there was little social recognition, low remuneration of these professionals and problems in the management of the pandemic by the government and health institutions, which negatively impacted the work activity of these workers.

RESUMO: A hidroterapia apresenta crescente aplicação no ramo da reabilitação animal, com o intuito de aumentar a força, resistência muscular e amplitude de movimento articular, além de reduzir a dor e melhorar o condicionamento físico do paciente. Assim como a hidroterapia, a atividade desenvolvida em solo é indicada para diversas afecções, inclusive para pacientes hipertensos, com atrofia muscular ou com sobrepeso. São escassos os estudos que avaliam a segurança de testes incrementais em esteira aquática e em esteira seca em American Pit Bull Terriers. Este estudo teve como objetivo avaliar os efeitos da atividade em esteira aquática e em esteira seca sobre os parâmetros fisiológicos de cães. Para isto, cães da raça American Pit Bull Terrier (n=12) machos, adultos, saudáveis e não treinados foram submetidos a teste de esforço incremental (TEI) em hidroesteira com água (Grupo I) e sem água (Grupo II). A frequência cardíaca (FR), frequência respiratória (FR), temperatura retal (TR), pressão arterial sistólica (PAS) e avaliação eletrocardiográfica, foram aferidas antes da atividade (T0), imediatamente após (T1), 30 minutos após (T2) e 90 minutos após o exercício (T3), e a concentração plasmática de lactato foi dosada nos momentos T0, T1 e T2. Os resultados foram submetidos ao teste de Shapiro-Wilk, análise de variância (ANOVA) e pelo Teste de Tukey, considerando significativo o valor de P < 0.05. Houve diminuição da frequência respiratória (P = 0,00674) após a atividade em esteira aquática, que se mostrou mais exigente que a atividade em esteira terrestre, considerando a apresentação de padrão respiratório mais lento e profundo. As sessões de exercício em ambos os grupos não elevaram a concentração de lactato. O teste de esforço incremental em esteira aquática, ou em esteira seca, pode ser desenvolvido com segurança por cães American Pit Bull saudáveis.

ABSTRACT: The application of hydrotherapy is growing in the field of animal rehabilitation to improve strength, endurance, fitness, and range of motion, in addition to reducing pain. In the same way, land-based activity is recommended for various conditions, including hypertension, muscle atrophy, and obesity. There is a lack of studies that evaluate the safety of incremental exercise in American Pit Bull Terriers. This study assessed the influence of activity on underwater and dry land treadmills on the physiological parameters of dogs. In this regard, 12 adult, male, healthy, and untrained American Pit Bull Terriers were subjected to an incremental exercise test (IET) on the underwater treadmill (Group I) and the dry land treadmill (Group II). Heart rate (HR), respiratory rate (RR), rectal temperature (RT), systolic blood pressure (SBP), and electrocardiographic evaluation, were evaluated before activity (T0), immediately after (T1), 30 min after (T2), and 90 min after the end of exercise (T3), and plasmatic lactate concentrations were measured at T0, T1, and T2 time points. Results obtained were submitted to the Shapiro-Wilk test, ANOVA and Tukey’s test, considering P<0.05. Water activity induced a reduction in RR (P=0.00674) in all examinations after the test on the underwater treadmill and proved to be more demanding than activity on the land treadmill, considering the presence of a deeper and slower RR. Exercise sessions in both groups did not elevate the lactate concentration. The IET can be performed safely on an underwater or dry land treadmill in healthy American Pit Bulls.

ABSTRACT This research was conducted to determine optimal dietary histidine requirement of grow-out Nile tilapia, Oreochromis niloticus, based on muscle development, expression of muscle-growth-related genes, and blood parameters. Fish (n = 288, initial body weight of 64.17±0.53 g) were fed extruded diets with graded levels of histidine (4.23, 5.44, 7.17, 8.91, and 11.57 g kg−1), containing approximately 289 g kg−1 crude protein and 3565 kcal kg−1 digestible energy. The study followed a completely randomized design with five treatments and four replicates each, for 65 days. There was a quadratic effect of dietary histidine on final body weight, feed conversion, and net protein utilization, and the best values were optimized at 8.09, 7.88, and 7.33 g kg−1, respectively. Feed intake, hepatosomatic index, survival, body composition, and blood parameters of total protein, glucose, triglycerides, cholesterol, hematocrit, and hemoglobin were not affected by dietary treatments. Predominance of hypertrophic growth and higher mRNA levels of myogenin and MyoD were observed in fish fed histidine from 5.44 to 11.57 g kg−1 compared with fish fed histidine at 4.23 g kg−1. The mRNA expression of myostatin was not affected by dietary treatments. The dietary requirement of histidine for grow-out Nile tilapia was determined at 8.09 g kg−1, considering growth performance, muscle development, and gene expression responses.

ABSTRACT This study aimed to determine the length-weight relationship and mathematical models to predict dressed and fillet weight and yield and fillet composition of wild traíra, Hoplias malabaricus (Bloch, 1794). A total of 80 marketable-sized fish from 292.28 to 2879.57 g and 32.06 to 61.19 cm were used. The length:weight ratio was estimated using the equation: W = a × L b, in which W is body weight (g) and L is length (cm). The models of dressed and fillet weight and yield and body were elaborated using first-order ( y ^ i = β 0 + β 1 x i ) or second-order ( y ^ i = β 0 + β 1 x i + β 1 x i 2 ) linear regression analyses. The value of slope b in the length:weight ratio was 3.3732 and intercept was 0.0029. The prediction equations obtained for dressed weight, fillet weight, dressed yield, fillet yield, fillet gross energy, moisture, crude protein, crude lipid, and ash were, respectively: y ^ = 0.3244 + 0.9373 W, y ^ = 0.7651 + 0.4181 W, y ^ = 939.8015 + 0.0019 W, y ^ = 420.55170 + 0.0064 W, y ^ = 997.9600 + 0.0630 W, y ^ = 810.6500 − 0.0085 W, y ^ = 184.080 − 0.0111 W, y ^ = 3.1131 + 0.0049 W, and y ^ = 10.6110 + 0.0009 W, in which W is the body weight of fish (g). We demonstrated the possibility of elaborating realistic expressions to describe degutted weight, fillet weight, and fillet composition. However, lower mathematical adjustment was observed to estimate realistic prediction of dressed and fillet yield.

ABSTRACT The objective of this study was to evaluate the oxidative stability of cashew nut meal (CNM) at 180 days of storage and the effects of its use in the feed of meat quails. A total of 280 animals at seven days of age, of both sexes, were distributed in a completely randomized design with five treatments, in a 2 × 2 + 1 factorial arrangement, and seven replicates of eight birds each. The treatments were a control diet without CNM and diets containing levels of 12.5 or 25% of new CNM (NCNM) or stored for 180 days (SCNM). The lipid oxidation of the brans was evaluated by determining the acidity index and peroxide index. The parameters evaluated were the quail performance, metabolizable coefficients and energy of diets, carcass characteristics, relative weights of the liver and pancreas, and bone parameters. The acidity of cashew nut meal was 4.66% and 6.16 (% in oleic acid) for NCNM and SCNM, respectively. Independent of the storage, inclusion of CNM resulted in higher metabolizable energy values in the diet, reduced intake, and, because weight gain did not vary, feed conversion improved compared with the control treatment. Carcass traits, relative weights of liver and pancreas, as well as bone growth and quality were not affected by dietary treatments. Despite the hydrolytic rancidity, CNM can be used in the diets for meat quails at up to 25% of inclusion.

Abstract: En Es | Text: En Es | PDF: En | PDF: Es

Colliroja, Astyanax fasciatus, is a new aquaculture species, and information on its dietary essential amino acid requirements is lacking. The whole body composition of 120 farmed fish (16.2 ± 8.8 g) was determined to estimate the dietary essential amino acid requirement based on the ideal protein concept ((each essential amino acid/lysine) x100), and the findings were correlated to the whole body essential amino acid content of Nile tilapia Oreochromis niloticus. The dietary essential amino acids, including cysteine and tyrosine, accounted for 5.46, 4.62, 1.16, 3.28, 5.63, 2.01, 2.59, 2.84, 4.66, 3.39, 0.65, and 3.51% of the total protein for lysine, arginine, histidine, isoleucine, leucine, methionine, methionine+tyrosine, phenylalanine, phenylalanine+tyrosine, threonine, tryptophan, and valine, respectively. There were positive linear and high correlations (r = 0.971) between the whole body amino acid profiles of colliroja and Nile tilapia. Thus, the whole body amino acid profile of colliroja might be used to estimate accurately the essential amino acid requirement.

Colirroja, Astyanax fasciatus, es una nueva especie de la acuicultura y no hay información sobre sus requerimentos de aminoácidos esenciales en la dieta. Se determinó la composición corporal de 120 peces de cultivo (16,2 ± 8,8 g) para estimar los requirimientos nutricionales de aminoácidos essenciales en la dieta, incluyendo cistina y tirosina, basada en el concepto de proteína ideal ((cada aminoácido essencial/lisina) x 100) y los resultados se correlacionaron con el perfil corporal de la tilapia del Nilo Oreochromis niloticus. El perfil dietético de aminoácidos essenciales explica el 5,46, 4,62, 1,16, 3,28, 5,63, 2,01, 2,59, 2,.84, 4,66, 3,39, 0.65 y 3,51% de la proteína, respectivamente para lisina, arginina, histidina, isoleucina, leucina, metionina, metionina+cistina, fenilalanina, fenilalanina+tirosina, treonina, triptófano y valina. Hubo una alta correlación lineal positiva (r = 0,971) entre el perfil corporal de aminoácidos de colirroja y el de tilapia del Nilo. Por lo tanto, el perfil corporal de los aminoácidos basado en el concepto de proteína ideal podría ser utilizado para estimar con precisión el requisito de aminoácidos essenciales de colirroja.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

O comprometimento pulmonar é uma das manifestações extra-articulares da artrite reumatóide e pode ser devido à própria doença ou secundário às medicações utilizadas para seu tratamento. Este trabalho relata um caso de uma paciente de 60 anos de idade com diagnóstico de artrite reumatoide que evoluiu com múltiplos nódulos pulmonares durante o tratamento com leflunomida.

Pulmonary involvement is one of the extra-articular manifestations of rheumatoid arthritis and can be due to the disease itself or secondary to the medications used in order to treat it. We report the case of a 60-year-old woman who had been diagnosed with rheumatoid arthritis and developed multiple pulmonary nodules during treatment with leflunomide.

O objetivo deste trabalho foi avaliar a estabilidade oxidativa do farelo integral de arroz parboilizado (FIAP) durante o armazenamento e os efeitos do seu uso na alimentação de codornas de corte. Foram utilizados 245 animais com sete dias de idade, de ambos os sexos, distribuídos em delineamento inteiramente casualizado, com cinco tratamentos, em arranjo fatorial 2x2+1, e sete repetições de sete aves. Avaliaram-se os seguintes tratamentos: dieta controle, sem adição de FIAP; e níveis de inclusão, na dieta controle, de 10 e 20% de FIAP armazenado por 180 dias (FIAPA) ou de FIAP novo (FIAPN). Houve oxidação lipídica do FIAP durante o armazenamento, e o índice de acidez foi de 4,25 e 63,50 (% em ácido oleico) e o de peróxido foi de 15,64 e 38,28 meq kg-1 para FIAPN e FIAPA, respectivamente. A inclusão do FIAP resultou em menor digestibilidade da matéria seca e do nitrogênio e em maior valor de energia metabolizável da ração, em comparação à ração controle. A inclusão de 20% de FIAPA resultou em menor energia metabolizável da ração do que a adição do FIAPN. As inclusões não influenciaram desempenho, características da carcaça, pesos relativos do fígado e do pâncreas, e crescimento e qualidade óssea. O FIAPA, mesmo com rancidez, pode ser utilizado na alimentação de codornas de corte em níveis de até 20% de inclusão.

The objective of this work was to evaluate the oxidative stability of parboiled rice bran (PRB) during storage and the effects of its use on meat quail feeding. Two hundred forty-five animals, with seven days of age, of both sexes, were used, distributed in a completely randomized design, with five treatments in a 2x2+1 factorial arrangement and seven replicates of seven chicks. The following treatments were evaluated: control diet, without PRB; and inclusion levels of 10 and 20% of 180-day-storaged PRB (SPRB) or of new PRB (NPRB) in the control diet. There was lipid oxidation of PRB during storage, the acid index was 4.25 and 63.50 (% as oleic acid) and the peroxide index was 15.64 and 38.28 meq kg-1 for NPRB and SPRB, respectively. The inclusion of PRB resulted in lower dry matter and nitrogen digestibility and in higher metabolizable energy value of feed when compared to the control diet. The inclusion of 20% SPRB resulted in lower metabolizable energy of feed than the addition of NPRB. The inclusions did not influence performance, carcass traits, relative weights of the liver and pancreas, and bone growth and quality. The SPRB, although rancid, can be used as feed for meat quail at levels up to 20% inclusion.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Avaliou-se a prevalência e a contagem parasitária das diferentes espécies de helmintos de ovinos provenientes da microrregião de Jaboticabal, região Noroeste de São Paulo. Para tanto, foram utilizados 66 animais naturalmente infectados, de quatro a 36 meses de idade, criados em regime extensivo. Os resultados necroscópicos revelaram a presença de sete gêneros e 12 espécies, com a seguinte prevalência e a média de parasitismo: Haemonchus contortus: 100,0% (2947,2); Trichostrongylus colubriformis: 90,9% (3048,8); Cooperia curticei: 56,0% (256,5); Oesophagostomum columbianum: 48,4% (36,0); Cooperia punctata: 30,3% (94,5); Trichostrongylus axei: 22,7% (26,5); Strongyloides papillosusi: 19,6% (83,0); Haemonchus contortus (L4): 7,5% (17,2); Cooperia pectinatai: 10,6% (12,9); Trichuris ovis: 10,6% (0,6); Cooperia spatulata 4,5% (0,3); Capillaria bovis: 4,5% (0,1). A carga parasitária média foi de 6.524,7 helmintos por animal. Haemonchus contortus (Adultos e L4) e Trichostrongylus colubriformis corresponderam a 45,4% e 46,7% da carga parasitária média total, respectivamente. Pode-se concluir que as duas espécies de helmintos mais abundantes e importantes da microrregião de Jaboticabal/São Paulo foram Trichostrongylus colubriformis e Haemonchus contortus, sendo que essas duas espécies perfizeram 92,1% da distribuição percentual dos helmintos recolhidos de todos os animais. Tais resultados demonstram a importância em se realizar um monitoramento das contagens de ovos por grama de fezes (OPG) dos rebanhos desta região, quando o método FAMACHA for empregado em uma determinada propriedade, uma vez que este método de controle, geralmente, não permite diagnosticar os danos/sinais clínicos desencadeados nos animais pelo T. colubriformis, em função de essa espécie não possuir hábito de hematofagismo sobre os hospedeiros.

This study evaluated the prevalence and counting parasitism of different species of helminths of sheep from the micro-region of Jaboticabal of São Paulo state. For this, 66 animals naturally infected, four to 36 months of age, raised in pasture, were selected. The results of necropsy revealed the presence of seven genera and 12 species with the following prevalence and mean count: Haemonchus contortus: 100.0% (2947.2); Trichostrongylus colubriformis: 90.9% (3048.8); Cooperia curticei: 56.0% (256.5); Oesophagostomum columbianum: 48.4% (36.0); Cooperia punctata: 30.3% (94.5); Trichostrongylus axei: 22.7% (26.5); Strongyloides papillosusi: 19.6% (83.0), Haemonchus contortus (L4): 7.5% (17.2), Cooperia pectinatai: 10.6% (12.9), Trichuris ovis: 10.6 % (0.6); Cooperia spatulata 4.5% (0.3); Capillaria bovis: 4.5% (0.1). The mean parasitism of helminthswas 6524.7 per animal. Haemonchus contortus (adults and L4) and Trichostrongylus colubriformis corresponded to 45.4% and 46.7% of the average worm burden totally, respectively. Based in the results obtained in this study, can be concluded that the two most abundant species of helminths and important, the micro-region of Jaboticabal are Trichostrongylus colubriformis and Haemonchus contortus, and these two species amounted to 92.1% of the distribution percentage of helminths collected from all animals. These results demonstrate the importance of conducting a counts of eggs per gram of feces (EPG) in the herds of this region when FAMACHA is used on a particular property, since this method control does not allow to diagnostic the damage/clinical signs in animals infected by T. colubriformis, because this specie does not have hematophagism habit on animals.
