    Free radical generation is an important step in pathogenesis of ethanol associated liver injury. Administration of ethanol induces an increase in lipid peroxidation both by enhancing the production of oxygen reactive species and decreasing levels of endogenous antioxidants. This work focuses the generation of free radical provoked by a chronic dose of ethanol. The objective of this investigation was to study the effect of 4 weeks chronic ethanol administration (20% in water) on liver lipid peroxidation , vitamin E in plasma and liver, and hepatic glutathione concentration. The animals were sacrificed in 0 and 24 hours after the ethanol administration. The control group received only distilled water during this period. Ethanol administration decreased the hepatic and plasmatic vitamin E in all groups, when compared to controls. The group sacrificed 24 hours after ethanol demonstrated the lowest concentration of vitamin E in liver (5,96±3,30 µg/g) in relation to control group (35,78±9,23 µg/g) and 0 hours group (10,30±1,59 µg/g). Concentration of SRATB was higher in liver of rats that received ethanol. Glutathione were elevated by ethanol administration. In conclusion, chronic ethanol administration provokes an imbalance in antioxidant system, inducing liver lipid peroxidation in rats and decreased vitamin E levels.A geração de radicais livres é um passo importante na patogênese da injúria hepática, associada à ingestão de etanol. O etanol induz a aumento na peroxidação lipídica por dois mecanismos: maior produção de espécies reativas de oxigênio e/ou diminuição dos níveis dos antioxidantes endógenos. Este trabalho enfoca a geração de radicais livres em ratos, após a ingestão crônica de etanol na água (20%), pelo período de 4 semanas.O objetivo do trabalho foi investigar o efeito do etanol sobre a peroxidação lipídica plasmática e hepática (medida por SRATB), vitamina E em plasma e fígado e glutationa hepática. Os animais receberam etanol por um período experimental de 4 semanas e foram sacrificados em 2 períodos distintos: 0 hora após o término das 4 semanas e 24 horas após o etanol ser retirado e substituído por água.Os animais que receberam etanol mostraram uma ingestão alimentar diminuída e alcançaram um peso menor, quando comparados aos ratos que receberam apenas água durante o experimento (p < 0,05). O grupo sacrificado 24 horas após,demonstrou a concentração mais baixa de vitamina E hepática (5,96±3,30 µg/g) em relação ao Grupo-Controle (35,78±9,23 µg/g) e ao Grupo Etanol 0 horas (10,30±1,59 µg/g). As concentrações hepáticas de SRATB foram encontradas em níveis aumentados nos animais que receberam etanol. Os valores de glutationa também foram afetados e se mostraram aumentados. Conclui-se que a administração crônica de etanol leva a uma alteração no sistema de defesa antioxidante, diminuindo os valores de vitamina E e aumentando os valores de GSH, provocando maior peroxidação lipídica

    Introduction: There is an increasingly common search for nutritional supplements among gym clients, often without appropriate orientation. Objective: The objective of the present investigation was to determine the use of nutritional supplements by persons practicing physical exercise at gyms in Ribeirão Preto-SP and the impact of this in the body composition.Methods: A questionnaire was applied to 102 males aged 20 to 40 years at 10 gyms in Ribeirão Preto-SP. After responding to the questionnaire, 30 individuals were submitted to evaluation of body composition and classified into 3 groups of 10 subjects each: no consumption of supplements (CG), exclusive consumption of protein supplements (PG), and use of protein-energy supplements (PEG). Results: The results showed that 52% of the subjects consumed some type of supplement. Muscle building was practiced by 92% of the interviewees, with an increase in lean mass being the major objective reported. The amount of protein consumed by PG and PEG subjects by ingesting the supplements represented, on average, 47% and 48%, respectively, of the daily protein needs considering the recommendation of 1 g protein/kg body weight. While the nutritionist is the professional most frequently associated with diets, the muscle building instructor is the professional most frequently consulted by the gym clients for the use of supplements. The evaluation of body composition revealed similar percent lean mass and percent body fat for the subjects who used supplements or not..Conclusion : The consumption of supplements by gym clients is elevated, often without appropriate specialized guidance, with no difference in body composition being observed when these products are consumed.Introdução : A procura por suplementos nutricionais está tornando-se cada vez mais comum entre os freqüentadores de academias de ginástica, muitas vezes sem uma orientação adequada. Objetivo : O objetivo desse trabalho foi verificar o uso de suplementos nutricionais por praticantes de atividade física em academias de Ribeirão Preto-SP e seu impacto na composição corporal. Métodos: Para realização da pesquisa foram aplicados questionários em 102 indivíduos, do sexo masculino, com idades entre 20 e 40 anos, em 10 academias de ginástica de Ribeirão Preto-SP. Após o preenchimento do questionário, 30 indivíduos foram submetidos à avaliação da composição corporal e classificados em 3 grupos com 10 indivíduos: sem consumo de suplementos (GC), consumo exclusivo de suplementos protéicos (GP) e uso de suplementos protéico-energéticos (GPE). Resultados:Os resultados mostraram que 52% utilizam algum tipo de suplemento. A musculação era praticada por 92% dos entrevistados, sendo o aumento de massa magra, o principal objetivo relatado. A quantidade protéica consumida por meio dos suplementos significava, em média, 47% e 48% respectivamente para GP e GPE, da proteína que seria necessária por dia, considerando a recomendação de 1g proteína por quilo de peso corporal. Enquanto o nutricionista é o profissional mais procurado para a orientação de dietas, o instrutor de musculação é o profissional mais requisitado pelos alunos para a utilização de suplementos. A avaliação da composição corporal mostrou percentual de massa magra e percentual de gordura corporal semelhantes entre os que faziam ou não uso de suplementos. Conclusão : O consumo de suplementos pelos freqüentadores de academias é elevado, muitas vezes sem uma orientação especializada e adequada, e pelos métodos utilizados não se verificou diferença na composição corporal com a utilização destes produtos.

    Objective The ketogenic diet is used as a therapeutic alternative for the treatment of epilepsy in patients with refractory epilepsy. It simulates biochemical changes typical of fasting. The present study verified the nutritional impact of the ketogenic diet on children with refractory epilepsy. Methods Nutritional status data (dietary, biochemical and anthropometric measurements), seizure frequency, and adverse events were collected from the medical records and during outpatient clinic visits of children over a period of 36 months. Results Of the 29 children who initiated the ketogenic diet, 75.8% presented fewer seizures after one month of treatment. After six months, 48.3% of the patients had at least a 90.0% decrease in seizure frequency, and 50.0% of these patients presented total seizure remission. At 12 months, eight patients continued to show positive results, and seven of these children remained on the ketogenic diet for 24 months. There was an improvement of the nutritional status at 24 months, especially in terms of weight, which culminated with the recovery of proper weight-for-height. There were no significant changes in biochemical indices (total cholesterol and components, triglycerides, albumin, total protein, creatinine, glycemia, serum aspartate transaminase and serum alanine transaminase). Serum cholesterol levels increased significantly in the first month, fell in the following six months, and remained within the normal limits thereafter. Conclusion In conclusion, patients on the classic ketogenic diet for at least 24 months gained weight. Moreover, approximately one third of the patients achieved significant reduction in seizure frequency, and some patients achieved total remission.OBJETIVO: A dieta cetogênica é empregada como uma terapia alternativa para o tratamento da epilepsia em pacientes com epilepsia refratária e simula as alterações bioquímicas de jejum. Neste trabalho, verificouse o impacto nutricional da dieta cetogênica em crianças com epilepsia refratária.\ud MÉTODOS: Os dados sobre o estado nutricional (bioquímica, alimentar e medidas antropométricas), a frequência de crises e os eventos adversos de crianças acompanhadas durante 36 meses foram coletados de prontuários médicos e visitas ambulatoriais.\ud \ud RESULTADOS: Vinte e nove crianças iniciaram o tratamento; após um mês, 75,8% apresentaram redução das crises. Em seis meses, 48,3% dos pacientes tiveram pelo menos 90,0% de redução na frequência de crises, e, desses, 50,0% obtiveram o controle completo das crises. Aos doze meses, oito pacientes continuaram a apresentar Resultados positivos, e, desses, sete permaneceram em dieta cetogênica durante 24 meses. Observouse melhora do estado nutricional aos 24 meses de tratamento, especialmente em termos de peso, o que indica a recuperação da condição peso para altura. Não houve mudanças significativas nos índices bioquímicos analisados (colesterol total e de componentes, triglicerídeos, albumina, proteína total, creatinina, glicemia, transaminase glutâmico oxalacética sérica e transaminase glutâmico pirúvico sérica). Os níveis de colesterol aumentaram significativamente no primeiro mês, mas diminuíram nos seis meses seguintes e, posteriormente, se mantiveram dentro dos valores de referência.\ud \ud CONCLUSÃO: Os pacientes em uso da dieta cetogênica clássica por pelo menos 24 meses apresentaram melhora de peso e cerca de um terço dos pacientes conseguiu uma redução significativa da frequência de crises, com alguns pacientes completamente livres delas

    Xenarthrans -anteaters, sloths, and armadillos- have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. Have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become.Fil: Marques Santos, Paloma.

    Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

    ATLANTIC-CAMTRAPS: a dataset of medium and large terrestrial mammal communities in the Atlantic Forest of South America

    Our understanding of mammal ecology has always been hindered by the difficulties of observing species in closed tropical forests. Camera trapping has become a major advance for monitoring terrestrial mammals in biodiversity rich ecosystems. Here we compiled one of the largest datasets of inventories of terrestrial mammal communities for the Neotropical region based on camera trapping studies. The dataset comprises 170 surveys of medium to large terrestrial mammals using camera traps conducted in 144 areas by 74 studies, covering six vegetation types of tropical and subtropical Atlantic Forest of South America (Brazil and Argentina), and present data on species composition and richness. The complete dataset comprises 53,438 independent records of 83 species of mammals, includes 10 species of marsupials, 15 rodents, 20 carnivores, eight ungulates and six armadillos. Species richness averaged 13 species (±6.07 SD) per site. Only six species occurred in more than 50% of the sites: the domestic dog Canis familiaris, crab-eating fox Cerdocyon thous, tayra Eira barbara, south American coati Nasua nasua, crab-eating raccoon Procyon cancrivorus and the nine-banded armadillo Dasypus novemcinctus. The information contained in this dataset can be used to understand macroecological patterns of biodiversity, community, and population structure, but also to evaluate the ecological consequences of fragmentation, defaunation, and trophic interactions. © 2017 by the Ecological Society of Americ

    ATLANTIC-PRIMATES: a dataset of communities and occurrences of primates in the Atlantic Forests of South America

    Get PDF
    Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta. The dataset includes 700 primate communities, 8,121 single species occurrences and 714 estimates of primate population sizes, covering most natural forest types of the tropical and subtropical Atlantic Forest of Brazil, Paraguay and Argentina and some other biomes. On average, primate communities of the Atlantic Forest harbor 2 ± 1 species (range = 1–6). However, about 40% of primate communities contain only one species. Alouatta guariba (N = 2,188 records) and Sapajus nigritus (N = 1,127) were the species with the most records. Callicebus barbarabrownae (N = 35), Leontopithecus caissara (N = 38), and Sapajus libidinosus (N = 41) were the species with the least records. Recorded primate densities varied from 0.004 individuals/km 2 (Alouatta guariba at Fragmento do Bugre, Paraná, Brazil) to 400 individuals/km 2 (Alouatta caraya in Santiago, Rio Grande do Sul, Brazil). Our dataset reflects disparity between the numerous primate census conducted in the Atlantic Forest, in contrast to the scarcity of estimates of population sizes and densities. With these data, researchers can develop different macroecological and regional level studies, focusing on communities, populations, species co-occurrence and distribution patterns. Moreover, the data can also be used to assess the consequences of fragmentation, defaunation, and disease outbreaks on different ecological processes, such as trophic cascades, species invasion or extinction, and community dynamics. There are no copyright restrictions. Please cite this Data Paper when the data are used in publications. We also request that researchers and teachers inform us of how they are using the data. © 2018 by the The Authors. Ecology © 2018 The Ecological Society of Americ

    Microbiological profile and nutritional quality of raw foods for neutropenic patients under hospital care

    No full text
    OBJECTIVE: This study aimed to analyze and compare the microbiological profile and vitamin C content of raw and cooked foods destined for neutropenic inpatients. METHODS: Three vegetables and nine fruits, raw and boiled, washed and sanitized were examined. Heat-tolerant coliforms and coagulase-positive staphylococci were counted and the presence of Salmonella spp was investigated. The vitamin C content was analyzed by a colorimetric reaction. The Statistical Package for Social Sciences (SPSS) software was used for statistical analysis and the nonparametric Wilcoxon test was used to compare the mean vitamin C values of the cooked and raw foods. The Spearman correlation test was applied to determine the associations between the parameters evaluated RESULTS: Salmonella spp was absent in all samples and the populations of coagulase-positive staphylococci and heat-tolerant coliforms were below the minimum detectable limits of the methods employed (< 100 colony forming units (CFU)/g and < 3 most probable number (MPN)/g, respectively). There was a significant loss of vitamin C in the cooked foods, 38.9% on average, compared to the raw foods, a loss that was positively correlated with cooking time. CONCLUSION: The fresh fruits and vegetables properly sanitized in this study had a microbiological profile consistent with that required by Brazilian law. Furthermore, the nutritional value of the neutropenic diet is diminished, at least in terms of the vitamin C content
