ABSTRACT

ABSTRACT: This study was conducted to evaluate the effects of dietary supplementation with biocomplexed selenium and chromium on the fatty acid profile of the breast and thigh of males and females broilers of the Label Rouge lineage. The experimental design was completely randomized arranged in a 3 x 2 factorial scheme corresponding to three diets (control; 0.40 ppm of chromium; 0.50 ppm of selenium) and two sexes. Each treatment consisted of three plots of five broilers. The fatty acid profile was evaluated in the breast and thigh samples. The addition of biocomplexed selenium in the broilers diets increased the content of long chain fatty acid of the omega 3 and 6 series (docosahexaenoic - DHA and arachidonic acids, respectively), the total of omega 6 and the stearic acid content on the breast (pectoralis major muscle). In addition, selenium supplementation caused a reduction in oleic acid content and in total of monounsaturated in the same muscle. Males had higher contents of linoleic and linolenic acids, and total of polyunsaturated; and lower content of oleic acid, total of monounsaturated and saturated in the thigh. The broilers supplemented with biocomplexed selenium and males presented better lipid quality in the muscle by breast and thigh, respectively.


RESUMO: Este estudo foi conduzido com o objetivo de avaliar os efeitos da suplementação dietética com selênio e cromo biocomplexados sobre o perfil de ácidos graxos do peito e da coxa de frangos de corte machos e fêmeas da linhagem Label Rouge. O delineamento experimental foi inteiramente casualizado em esquema fatorial 3 x 2 correspondendo a três dietas (controle; 0,40 ppm de cromo; 0,50 ppm de selênio) e dois sexos. Cada tratamento foi composto por três parcelas de cinco frangos de corte. O perfil de ácidos graxos foi avaliado nas amostras de peito e coxa. A adição de selênio biocomplexado na dieta de frangos de corte aumentou o teor de ácidos graxos de cadeia longa das séries ômega 3 e 6 (ácido docosahexaenóico - DHA e araquidônico, respectivamente), o total de ômega 6 e o conteúdo de ácido esteárico no peito (músculo pectoralis major). Além disso, a suplementação com selênio causou redução no teor de ácido oleico e no total de monoinsaturados no mesmo músculo. Os machos apresentaram maiores teores dos ácidos linoléico e linolênico e total de poliinsaturados; e menor conteúdo de ácido oleico, total de monoinsaturados e saturados na coxa. Os frangos suplementados com selênio biocomplexado e os machos apresentaram melhor qualidade lipídica no músculo do peito e coxa, respectivamente.

ABSTRACT

Se determinó la composición de ácidos grasos de 54 cepas microalgales colectadas del Perú y mantenidas en el Banco de Germoplasma de Organismos Acuáticos (IMARPE) con la finalidad de determinar su uso nutricional en la acuicultura. Para ello se realizaron cultivos en un volumen de 50 mL y se determinaron los porcentajes relativos de ácidos grasos mediante transesterificación directa y cromatografía de gases. En el grupo Chlorophyta las microalgas que presentaron los mayores valores de porcentaje relativo de ácidos grasos fueron Chlamydomonas reinhardtii (16:0; 41.2%), Scenedesmus obtusus (18:1n-7; 33.6%), Acutodesmus dimorphus (18:1n-9; 37.1%), Desmodesmus armatus (18:3n-3; 32.2%) y Tetraselmis contracta (16:4n-3; 16.5%). En cambio en el grupo Bacillariophyta, los ácidos grasos más abundantes fueron 16:1n-7 en Chaetoceros didymus (20.2%), 18:4n-3 en Navicula sp. (28.3%) y EPA en Asterionellopsis sp. (31.5%). Por otro lado, en el grupo Dinophyta, todas las cepas superaron el 20% de DHA, en particular, la cepa de Akashiwo sanguinea presentó el mayor porcentaje relativo de este ácido graso (29.9%) y de los ácidos grasos 16:0 (24.8%) y EPA (16%). Se discute el uso de estas cepas según su contenido de ácidos grasos.


In This work, we determinate the fatty acids composition and their nutritional value in 54 microalgal strains, collected from Peru and stored in Banco de Germoplasma de Organismos Acuáticos (IMARPE). The cultures were grown to 50 mL and analyzed by direct transesterification and gas chromatography. In the Chlorophyta group, the microalgaes that present the highest relative percentage of fatty acids were Chlamydomonas reinhardtii (16:0; 41.2%), Scenedesmus obtusus (18:1n-7; 33.6%), Acutodesmus dimorphus (18:1n-9; 37.1%), Desmodesmus armatus (18:3n-3; 32.2%) and Tetraselmis contracta (16:4n-3; 16.5%). Moreover in the Bacillariophyta group, the most abundant fatty acids were 16:1n-7 in Chaetoceros didymus (20.2%), 18:4n-3 in Navicula sp. (28.3%) and EPA in Asterionellopsis sp. (31.5%). By the other hand, in the Dinophyta group, all strains exceed the 20% of DHA, in particular Akashiwo sanguinea, it was strain to have the highest percentage of this fatty acid (29.9%) in addition to 16: 0 (24.8%) and EPA (16%). We discussed uses of these strains is according to their fatty acids content.

ABSTRACT

Various studies have demonstrated the impact of omega-3 fatty acids on the concentration of C reactive protein (CRP), pro-inflammatory eicosanoids, cytokines, chemokines and other inflammatory mediators. Therefore, the supplementation of these types of lipids may represent additional option treatment for chronic systemic diseases, such as Systemic Lupus Erythematous and other rheumatic diseases. The role of these lipids has not been well established, yet. However, it seems there is a direct relationship between its intake and the decrease of the disease clinical manifestations as well as of the inflammatory status of the patients. Thus, the aim of this manuscript is to present a thorough review on the effects of omega-3 fatty acids in patients with SLE. Bibliographic data set as the Medical Literature Analysis and Retrieval System Online (MEDLINE) and Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) were searched using as key words: systemic lupus erythematous (SLE), polyunsaturated fatty acids omega-3, eicosapentanoic acid (EPA), docosahexanoic acid (DHA), antioxidants and diet. Manuscripts published up to September 2013 were included. There were 43 articles related to the topic, however only 15 pertained human studies, with three review articles and 12 clinical studies.

ABSTRACT

Diversos estudos têm demonstrado a habilidade dos ácidos graxos ômega-3 em reduzir asconcentrações de proteína C-reativa (PCR), eicosanoides pró-inflamatórios, citocinas, quimiocinas e de outros biomarcadores da inflamação. Por essas propriedades, a suplementação com essa classe de lipídeos pode representar terapia adicional ao tratamento de doençasinflamatórias crônicas sistêmicas, como o lúpus eritematoso sistêmico (LES) e outrasdoenças reumáticas. O papel dessa classe de lipídeos no LES ainda não está bem estabelecido. No entanto, parece haver relação entre o consumo deste tipo de gordura e a diminuiçãodas manifestações e da atividade inflamatória da doença. Sendo assim, este artigo apresentarevisão da literatura científica sobre os efeitos dos ácidos graxos ômega-3 em pacientescom LES. Realizou-se levantamento bibliográfico junto aos bancos de dados Medical Literature Analysis and Retrieval System Online (MEDLINE) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), utizando-se como palavras-chave: lúpus eritematoso sistêmico (LES), ácidos graxos poli-insaturados ômega-3, ácido eicosapentaenoico(EPA), ácido docosahexaenoico (DHA), antioxidantes e dieta. Foram incluídos artigos publicados até setembro de 2013. Quarenta e três artigos relacionados ao tema foram encontrados. Após limitar a busca apenas para estudos realizados em seres humanos foram encontrados 15 artigos, sendo três de revisão e 12 ensaios clínicos.
