The species Pimelodus maculatus is one of the most abundant fish in many artificial reservoirs. Shows feeding plasticity and exploits all trophic levels in aquatic ecosystems. This study aimed to analyze and compare aspects of the diet of P. maculatus in two important tributaries (Taquari and Veados rivers) in the upper Paranapanema River system, and also investigate possible differences in the condition factor using its feeding habit as reference. Samplings were carried out every three months during 2011 and 2012 in two tributaries of Jurumirim's dam. After biometric analysis, fish were dissected to remove the stomachs that were fixed in formaldehyde 10% and conserved in alcohol 70%. The stomach content was analyzed under stereomicroscope and the food items were identified until the least possible taxonomic level. The diet was characterized based on the Alimentary Index (IAi). Feeding strategy and aspects of species autoecology were evaluated by the relation between abundance of prey-specific (Pi) and occurrence frequency (Fo) of the prey, and also was calculated the niche width of Levin (B). The condition factor was also established and values obtained in samples of both rivers were compared, correlating them with diet of the species

Obesity along with overweight has been considered one of the most serious public health problems in the world, especially because they are the main risk factors for many chronic diseases such as coronary heart disease, type II diabetes mellitus, hypertension and some types of tumors, which are associated with high mortality rates. The use of functional foods and appropriate diets to promote health has grown as a mechanism for prevention, control and treatment of chronic diseases such as obesity. Several ethnopharmacological studies indicate plants species for the treatment of disorders associated with obesity with a major attraction of this regimen is perceived as safer and more effective for health than the traditional treatment with appetite suppressants. Whereas both food intake and the oral treatment with different compounds can cause changes in gene expression and that a proper diet has been valuable as a mechanism for maintaining the body's vital functions, the objective of this project was to evaluate the effects of standardized extract of Brassica campestris L. in the decrease in weight and food intake control. In vivo trials of this product were conducted and studies of its effects on energy metabolism in non-obese mice and with obesity induced by hypercaloric diet. After induction of obesity by 8 weeks, animals were treated for 21 days with the extract orally. After 21 days the animals were killed and the effects of this product were evaluated on the daily feed intake and on body weight. According to the results obtained, the extract of Brassica campestris was not effective in reducing body weight of obese animals, and did not reduce food intake

The obesity has been considered one of the most serious public health problem in the worldwide scale, especially for being one of the main risk factors for many chronic diseases that characterize the metabolic syndrome. In addition to these diseases, obesity also causes dermatoses that affect not only the individual emotions but also cause various cutaneous infections. Thus, overweighting can be an agent that causes many types of stress: psychological, physical and social. In order to improve people’s life quality, several ethnopharmacological studies indicate plant species for the treatment of disorders associated with obesity due to the attraction of this regimen is perceived as safer and more health effective when compared to the treatment performed by traditional anorectic substances. If considered both food intake and also oral treatment with different compounds can promote change in the gene expression, besides an appropriate diet has been maintenance mechanism of body's vital functions. The aim of this work was to develop new standard methods for induced obesity and stress, which stress is induced through physical and psychogenic stressors in Swiss male mice. Also to evaluate the effect of supercritical extract of Physalis angulata L. on the food intake and corporeal weight loss

The main causes of illness and consequent death in patients affected by Diabetes Mellitus are the long-term complications. Depression can make it harder to control the level of glucose in the blood, as well as intensifying and worsening the clinical complications, thus reducing the quality of life. The aim of this study was to estimate the incidence of Diabetes Mellitus in Public Health Clinic in Presidente Prudente (SP) in patients enrolled in the Hiper-Dia Program. From October 2003 to July 2004, a descriptive survey was carried out. Data were obtained from doctor's records of 50 diabetes patients and also their answers to a specific questionnaire. The majority of the patients were female, had not completed elementary school, with a family income below five minimum wages, a nationally-defined amount related to the poverty line. It was observed that 24% of the patients had depression and 76% never followed a controlled diet. Pharmacological treatment was prescribed for 82% of the patients. Twenty-eight patients were receiving psyicological treatment, together with oral hypoglycemic agents. The glycated hemoglobin was measured in 68%. The association between depression and submission to treatment was not significant. No statistical association was found between the psychologically assisted patient's group and glucose control (p= 0.40), diet control (p= 0.37) and physical activities (p= 0.77). It was concluded that 24% patients had depression and the majority not under diet control, but 82% were under pharmacological treatment.

Os Isoptera são insetos sociais cujas colônias apresentam diversas castas, as quais têm um rígido sistema de divisão de trabalho que visa otimizar a eficiência da colônia. Estas castas apresentam morfologia específica, que capacita estes indivíduos a desenvolverem determinadas tarefas com eficiência. Os cupins apresentam aparelho bucal mastigador, constituído pelas seguintes peças bucais: labro, mandíbulas, maxilas, lábio, epifaringe e hipofaringe. Sua dieta alimentar é celulósica e bastante variada, sendo que estes insetos podem se alimentar de madeira (em vários estágios de decomposição), gramíneas, plantas herbáceas, serapilheira, fungos, líquens, partes de artrópodes e húmus. O estudo desse tipo de dieta é muito difícil, uma vez que o material já se encontra bastante decomposto antes de ser ingerido pelo animal. Cornitermes cumulans é uma espécie de cupim nativa do Cerrado brasileiro, pertencente à família Termitidae, subfamília Syntermitinae, que constrói ninhos em montículos, ricos em argila, que podem atingir até 4 metros de altura. Na parte interna dos ninhos, pode-se observar galerias grandes e de aspecto arredondado e um centro celulósico de coloração escura, de textura lisa e pouco resistente, onde os cupins armazenam um alimento, que parece ser previamente mastigado e depois regurgitado. Mesmo com a grande ocorrência desta espécie de cupim nas áreas de pastagens, seus verdadeiros hábitos alimentares são ainda pouco conhecidos. As informações disponíveis são contraditórias, uma vez que não está esclarecido a qual grupo funcional C. cumulans pertence e se existe realmente uma alimentação “in situ” desta espécie no campo. Em vista do exposto, este estudo teve como objetivo geral esclarecer o hábito alimentar de C. cumulans e a natureza química do alimento armazenado no ninho para compará-lo com o alimento coletado pelos...

Fibers are non-digestible materials by human organism, and they are insoluble in specific conditions. The corn fiber has been used as an alternative to enrich the food products for human consumption, in order to add nutritious value to this co-product. This study aimed at determining the chemical and fractions components of corn fiber, extracted by semi-wet milling in laboratory (LabF), and by semi-humid milling in industrial process (IndF); and microbiological analyses were perform in the last fraction. The fiber composition differed significantly among these two products as to moisture, ash, lipids, proteins, insoluble dietary fiber, neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose and lignin contents. The sample IndF showed microbiological parameters in compliance with the specifications for consumption. The investigated corn fiber may effectively contribute to increase the fiber intake in the diet. As the industrially processed fiber (IndF) showed compliant microbiological parameters with the specifications for food, this component might be incorporated into the food products formulation.
