Abstract: Mushrooms of the genus Agaricus are noted for their pharmacological and culinary properties. In this study, it was performed a critical literature review, focusing primarily on aspects of the chemical composition of these mushrooms whose pharmacological properties and nutritional composition characterize them as functional foods. It was also discussed articles conducted in vitro and in vivo proving the high antioxidant potential of the Agaricaceae family, in addition to articles which emphasize the toxicity characteristics and safety for its use in therapy or in human nutrition. These mushrooms exhibit numerous bioactive substances as well as safety regarding toxicity, which characterize them as functional foods. Despite the countless beneficial effects on human health, mushrooms of the genus Agaricus are little known by the population, making it necessary partnership and combined efforts among producers, industries and researchers in order to disseminate, research and consumption of these foods.

Abstract: An experiment was developed to determine the effect of addition of the marine alga Lithothamnium calcareum in the apparent digestibility of a low quality forage. Twelve adult lambs were kept in metabolical individual cages using a randomly design with three replications and four treatments as follows: I - Brachiaria decumbens grass hay, processed after the seed harvest; II - Hay plus 1000 ppm of calcium from CaCO3 (p.a.); III - Hay plus 1000 ppm of calcium from mineral supplement of alga; IV - Hay plus 2000 ppm of calcium from mineral supplement of alga. The mineral supplement of alga increased the digestibility of crude protein in 7,5% with dosage 1000 ppm and in 12% with dosage of 2000 ppm, when compared with control treatment, but such changes were not significant (P < 0,05). No differences were observed for dry matter and crude fiber. Um experimento foi conduzido para determinar o efeito da adi o de alga marinha Lithothamnium calcareum na digestibilidade aparente de uma forragem de baixa qualidade. Doze carneiros adultos foram distribuídos em gaiolas metabólicas, inteiramente casualizadas com três repeti es. Os tratamentos utilizados foram: I - Feno de capim Brachiaria decumbens, confeccionado após a colheita das sementes; II - Feno mais 1000 ppm de cálcio proveniente do carbonato de cálcio (p.a.); III - Feno mais 1000 ppm de cálcio proveniente do suplemento mineral de alga (L.C. - 400); IV - Feno mais 2000 ppm de cálcio proveniente do suplemento mineral de alga (L.C. - 400). O suplemento mineral aumentou a digestibilidade da proteína bruta em 7,5% na dosagem de 1000 ppm e em l2% na dosagem de 2000 ppm, quando comparados ao tratamento controle, mas tais mudan as n o foram significativas (P < 0,05).

Abstract: Objetivando avaliar a composi o química e a digestibilidade aparente de feno de Brachiaria humidicola (Rendle) Schweickerdt, após a colheita de sementes, foi realizado um experimento nas dependências do Departamento de Zootecnia da Escola de Veterinária da Universidade Federal de Goiás. Utilizou-se quatro carneiros adultos, castrados, sem ra a definida, com bolsas coletoras de fezes e alojados em gaiolas individuais de metabolismo durante 17 dias, sendo 7 de adapta o e 10 de coleta. A digestibilidade aparente da matéria seca (53,64%) concorda plenamente com o resultado encontrado "in vitro" (53,37%). Na base de matéria seca, o feno apresentou 53,40% de N.D.T., baixo nível de proteína bruta (3,03%) com baixo coeficiente de digestibilidade (11,88%). Nas condi es do presente experimento conclui-se que a fena o da Brachiaria humidicola, após a colheita mecanica das sementes, prejudicou o valor nutritivo do feno, principalmente, a proteína bruta e sua digestibilidade. A trial to study the apparent digestibility of Brachiaria humidicola (Rendle) Schweickerdt, grass, was carried out at the Departamento de Zootecnia da Universidade Federal de Goiás. The seeds of B.humidicola have a good commercial value and the farmers utilized a grass of bad quality after mechanical harvest. Four adult lambs, castrated males, of unknown race, were used and placed in metabolical individual cages during 17 days, 7 for adaptation and 10 for collection period. The apparent digestibility of dry matter was 53.64% and ";in vitro"; 53.37%. On dry matter-basis the hay has 53.40% of TND value, a poor crude protein (3.03%) value with low coefficient of digestibility (11 .88%).

Abstract: the meaning that a product has for the consumer - which can be considered as symbolic or utilitarian - and the judgment made by an individual to evaluate the product meaning are both variables that have been studied to predict the buying behavior. the objective of this study was to verify the reliability of the model proposed by allen (1997), through the translation and validation of the scale of judgment and meaning of the product. the study sample was composed by 588 participants, with a good distribution between sex and age. results indicated the presence of two factors: rational judgment and meaning (18.33% of explained variance, with alpha of 0.76) and emotional judgment and meaning (15.97% of explained variance, with alpha of 0.73). after the analysis, all 19 original items of the scale were retained. the obtained data indicated the need for adaptation and enhancement of the scale to the national reality. apparently, the contradiction between the model proposed by allen (1997) and results found in this study reveals psychometric problems of the scale, suggesting the need for new studies to confirm this possibility.

Abstract: The purpose of this paper was the development a measure of judgment and meaning of the product valid for Brazilian consumers. It consisted in a two-stage study including both qualitative and quantitative approaches. In the qualitative stage, focus groups with 16 Brazilian participants allowed the generation of 40 items for a new scale of judgment and meaning of the product. After semantic validation and expert analysis, the found items composed a questionnaire administered to 684 participants in a paper-and-pencil survey. Results suggest that the items performed considerably better when compared to the previous version, indicating their potential of usage not only in Brazil, but also in other countries. The final measure remained with 20 items that were distributed in four factors, as pointed by the literature review. Two factors are related to judgment types (piecemeal and affective), whilst the other two are related to meaning types (utilitarian and symbolic). Additional results, as expected, showed that product's utilitarian meaning is positively correlated to a piecemeal judgment, whereas symbolic meaning is positively related to affective judgment. Managerial implications for marketing, and future research directions are proposed. O objetivo deste trabalho foi o desenvolvimento de uma escala de julgamento e significado do produto válida para os consumidores brasileiros. Ela consistiu em um estudo de dois estágios, incluindo tanto a abordagem qualitativa quanto a quantitativa. Na etapa qualitativa, a condu o de grupos focais com 16 participantes brasileiros permitiu a gera o de 40 itens para uma nova medida de julgamento e significado do produto. Após a valida o semantica e a análise de juízes, os itens encontrados compuseram um questionário que foi aplicado face-a-face a 684 participantes. Os resultados sugerem um desempenho muito melhor da medida quando comparado ao da vers o anterior da escala, indicando o seu potencial de uso n o só no Brasil, mas também em outros países. A escala final ficou com 20 itens que foram distribuídos em quatro fatores, como apontado pela revis o da literatura. Dois fatores est o relacionados aos tipos de julgamento (passo a passo e afetivo), enquanto os outros dois est o relacionados aos tipos de significados (utilitário e simbólico). Resultados adicionais, como esperado, mostraram que o significado utilitário do produto está positivamente correlacionado com um o julgamento passo-a-passo, enquanto o significado simbólico está positivamente relacionado com o julgamento afetivo.
