| We previously reported that both the high-carbohydrate diet (HCD) and high-fat diet (HFD) given for two months promote lipid deposition and inflammation in the liver and brain of mice. The results obtained indicate a tissue-specific response to both diets. Herein, we compared the effects of HCD and HFD on fatty acid (FA) composition and inflammation in the gastrocnemius muscle. Male Swiss mice were fed with HCD or HFD for 1 or 2 months. Saturated FA (SFA), monounsaturated FA (MUFA), n-3 polyunsaturated FA (n-3 PUFA), and n-6 PUFA were quantified. The activities of stearoyl-CoA desaturase 1 (SCD-1), Δ-6 desaturase (D6D), elongase 6, and de novo lipogenesis (DNL) were estimated. As for indicators of the inflammatory tissue state, we measured myeloperoxidase... |

| Obesity is often associated with changes in cardiac function; however, the mechanisms responsible for functional abnormalities have not yet been fully clarified. Considering the lack of information regarding high-saturated-fat diet-induced obesity, heart function, and the proteins involved in myocardial calcium (Ca2+) handling, the aim of this study was to test the hypothesis that this dietary model of obesity leads to cardiac dysfunction resulting from alterations in the regulatory proteins of intracellular Ca2+ homeostasis. Male Wistar rats were distributed into two groups: control (C, n=18; standard diet) and obese (Ob, n=19; high-saturated-fat diet), which were fed for 33 weeks. Cardiac structure and function were evaluated using echocardiographic and... |

| Para se avaliar o perfil de ácidos graxos da carne de coelhos desmamados em diferentes idades, recebendo dietas com ou sem óleo de soja e oriundos de matrizes alimentadas com dois níveis de energia, foram abatidos 80 animais aos 70 dias de idade. O delineamento experimental foi em esquema fatorial 2 x 2 x 2 (dietas com 2600 e 2800 kcal ED até a desmama “versus” desmama com 28 e 35 dias versus dietas com ou sem inclusão de óleo de soja da desmama ao abate), com oito tratamentos e dez repetições. Após o abate, a carne da coxa direita dos animais foi coletada e, dentro de cada grupo, foi submetida às análises químicas. Os teores de ácidos graxos na carne da coxa dos coelhos não foram influenciados pelos diferentes níveis de ED das dietas fornecidas até a... |

| ABSTRACT: The aim of this study was to evaluate the carcass characteristics and the physicochemical parameters, centesimal composition, and fatty acid profile of the longissimus lumborum muscle of crossbred steers on a Brachiaria (Syn. Uruchloa) brizantha cv. Marandu pasture during the growing and finishing phases. Twenty-two uncastrated steers ½ Holstein/Zebu, with an average initial weight of 210 kg ± 8.2 kg and eight months of age, were distributed in a completely randomized design, in which the experimental period was fractionated in to three seasons associated with two nutritional plans (NP1 and NP2) and 11 animals by treatment: NP1- mineral mixture ad libitum in rainy seasons + nitrogen/energy supplement at 1 g.kg-1 body weight (BW) in the dry... |
