Abstract
The concerning of plastic pollution in different ecosystems has been worsened by the widespread presence. Phthalate esters (PAEs), plasticizers found in everyday products, can migrate into the environment, especially into the oceans. Researches on their effects on cetaceans are still rare. Metabolomics helps assess perturbations induced by exposure to PAEs, which act as persistent endocrine disruptors. Four PAEs (dimethyl phthalate - DMP, diethyl phthalate - DEP, dibutyl phthalate - DBP, and di(2-ethylhexyl phthalate - DEHP) were analyzed, along with cholesterol and fatty acid profiles of P. blainvillei's blubber samples collected in southern Brazil. The study reveals pervasive contamination by PAEs - especially DEHP, present in all samples - with positive correlations between DEP content and animal size and weight, as well as between the DEHP amount and the C17:1 fatty acid. These findings will be relevant to conservation efforts aimed at this threatened species and overall marine ecosystems.

Abstract
Abstract The consumption and consequent production of butter has increased considerably in recent years. In order to know the butters sold in Brazil, the study aimed to analyze butters of Brazilian, French, Italian and Argentine origin. The samples were analyzed for fat content, moisture, Defatted Dry Extract (DDE), and total acidity for comparison with Brazilian legislation. The levels of chlorides, protein, ash, total dry extract, water activity, color and determination of the lipid profile were also determined. In all analyses, there was a statistically significant difference between the samples. Some samples showed disagreement with the quality requirements recommended in Brazilian legislation for commercialization. Indeed, 10 samples did not present the minimum fat content required, varying from 68.53% to 77.31% in butters with salt and from 71.64% to 81.72% in those without salt. Eight samples presented humidity levels above the legal recommendations, varying from 17.05% to 20.28%. All products were in agreement with acidity levels. The predominant fatty acids in all samples were myristic acid (C14: 0), palmitic acid (C16: 0), stearic acid (C18: 0) and oleic acid (C18: 1n9). The regional influence, breed and handling of the animals and season of the year in which the milk was obtained for butter production, were suggested to be the main reason for the physical-chemical difference found between the samples.

Abstract
A nutrigenômica tem configurado, no meio científico e popular, como alternativa para prevenir doenças, cuja predisposição determinada geneticamente pode ser evitada ou estimulada, de- pendendo do ambiente no qual o indivíduo se insere. Este estudo questionou o potencial da nutrigenômica em mitigar ou gerar vulnerabilidades. Objetivou-se traçar o panorama da nutrigenômica no Brasil sob a perspectiva da Bioética. O estudo consistiu em um mapeamento quantitativo do panora- ma da nutrigenômica no cenário científico e popular do Brasil, e em uma análise bibliográfica exploratória com o intuito de identificar os agentes e pacientes morais, bem como as vulnerabilidades com vistas a promover uma reflexão à luz da Bioética. O cenário da nutrigenômica no Brasil, elaborado a partir de 18 textos científicos e de 600 conteúdos populares, indicou a prematuridade da área no contexto científico em confronto com uma ampla incorporação pelo meio popular. A incorporação da Bioética na questão foi analisada em 44 artigos científicos, a partir dos quais foram identificados como aspectos condicionantes de decisões do agente moral os contextos filosófico, biológico, cultural, legal e sanitário nos quais se insere. Foram elencadas as vulnerabilidades e mudanças de paradigmas necessárias para sua implementação no Brasil, a fim de diminuir o potencial de geração de vulnerabilidades. A Bioética pode e deve ter uma atuação mais ampla e efetiva nas questões da nutrigenômica ao normatizar, balizar e orientar o desenvolvimento dessa área promissora. Assim, deve visar às mudanças de paradigmas da ciência, dos profissionais, do mercado, do paciente e do consumidor para serem suprimidos os aspectos potenciais de geração das vulnerabilidades identificadas e contribuir para a qualidade de vida de todos os seres vivos desta e de futuras gerações.

Abstract
The dietary inclusion of feed additives to improve the carcass characteristics of the final product is of great importance for the pork production chain. The aim of our study was to evaluate the effects of the association of ractopamine (RAC) and conjugated linoleic acid (CLA) on the performance traits of finishing pigs during the last 26 days prior to slaughter. In total, 810 commercial hybrid barrows were used. Animals were distributed among treatments according to a randomised block design in a 3 × 3 factorial arrangement, with three RAC levels (0, 5 or 10 ppm) and three CLA levels (0, 0.3 or 0.6%). Pigs fed the diet with 5 ppm RAC had higher average daily feed intake (ADFI) (2.83 kg; P < 0.05) when compared with those fed 10 ppm RAC and the control diet (2.75 and 2.74 kg, respectively). Lower ADFI values (P < 0.01) were observed with the diets containing CLA compared with the control diet with no CLA (2.73 and 2.75 v. 2.85 kg/day, respectively). The average daily weight gain of pigs fed 5 and 10 ppm RAC was +148 and +173 g/dayhigher (P < 0.001), respectively, than those fed the control diet. Dietary RAC levels influenced (P < 0.001) feed conversion ratio (FCR), which was reduced as RAC levels increased, with the pigs fed 10, 5 and 0 ppm RAC presenting FCR values of 2.57, 2.71 and 3.05, respectively. FCR also improved (P < 0.05) with the inclusion of 0.6% CLA relative to the control diet (2.70 v. 2.84, respectively). There was a significant interaction between CLA × RAC levels (P < 0.01) for final BW, loin eye area (LEA) (P < 0.05) and backfat thickness (BT) (P < 0.05). The treatments containing 10 ppm RAC + 0.6% or 0.3% CLA increased LEA and reduced BT. In conclusion, the level of 10 ppm inclusion of RAC increased the overall performance parameters of pigs and therefore improved production efficiency. The combined use of RAC and CLA promoted a lower feed conversion ratio as well as better quantitative carcass traits, as demonstrated by the higher LEA and lower BT. The dietary inclusion of CLA at 0.3% improved feed efficiency, however, without affecting LEA or BT yields.

Abstract
BACKGROUND This study evaluated the effect of pomegranate seed oil (PSO) supplementation, rich in punicic acid (55 %/C18:3-9c,11 t,13c/CLNA), on the lipid profile and on the biochemical and oxidative parameters in the gastrocnemius muscle and adipose tissues of healthy rats. Linseed oil (LO), rich in linolenic acid (52 %/C18:3-9c12c15c/LNA) was used for comparison. METHODS Male Wistar rats (n = 56) were distributed in seven groups: control (water); LNA 1 %, 2 % and 4 % (treated with LO); CLNA 1 %, 2 % and 4 % (treated with PSO), po for 40 days. The percentages were compared to the daily feed intake. Fatty acid profile were performed by gas chromatography, antioxidant enzymes activity by spectrophotometer and the adipocytes were isolated by collagenase tissue digestion. Analysis of variance (ANOVA) was applied to check for differences between the groups (control, LNAs and CLNAs) and principal component analysis (PCA) was used to project the groups in the factor-place (PC1 vs PC2) based on the biochemical responses assessed in the study. RESULTS The fatty acids profile of tissues showed that the LNA percentages were higher in the animals that were fed LO. However, PA was only detected in the adipose tissues. Conjugated linoleic acid (CLA) was present in all the tissues of the animals supplemented with PSO, in a dose dependent manner, and 9c11t-CLA was the predominant isomer. Nevertheless there were no changes in the total weight gain of the animals, the weights of the tissues, and the oxidative stress parameters in the muscle. In addition, there was an increase in the size of the epididymal fat cells in the groups treated with PSO. Principal component analysis (PCA) showed that the CLNAs groups were arranged separately with a cumulative variance of 68.47 %. CONCLUSIONS The results show that PSO can be used as a source of CLAs but that it does not cause changes in body modulation and does not interfere in the antioxidant activity of healthy rats.

Abstract
Conjugated linoleic acid (CLA) is highly found in fats from ruminants and it appears to favorably modify the body composition and cardiometabolic risk factors. The capacity of CLA to reduce the body fat levels as well as its benefic actions on glycemic profile, atherosclerosis and cancer has already been proved in experimental models. Furthermore, CLA supplementation may modulate the immune function, help re-synthetize of glycogen and potentiate the bone mineralization. CLA supplementation also could increase the lipolysis and reduce the accumulation of fatty acids on the adipose tissue; the putative mechanisms involved may be its action in reducing the lipase lipoprotein activity and to increase the carnitine-palmitoil-transferase-1 (CAT-1) activity, its interaction with PPARγ, and to raise the expression of UCP-1. Although studies made in human have shown some benefits of CLA supplementation as the weight loss, the results are still discordant. Moreover, some have shown adverse effects, such as negative effects on glucose metabolism and lipid profile. The purpose of this article is to review the available data regarding the benefits of CLA on the energetic metabolism and body composition, emphasizing action mechanisms.

Abstract
AbstractObjectiveThe present study investigated how trans-fat is reported on the packaging of foods sold in a Brazilian supermarket.DesignThe present descriptive, cross-sectional study analysed the ingredient list, nutrition facts label and claims of no trans-fat on the packaging.SettingA large supermarket in Florianópolis, Brazil.SubjectsAll food products available at the supermarket.ResultsOf the 2327 study products, more than half had components containing trans-fat in the ingredient list, especially hydrogenated vegetable fat and its alternative names. A small percentage of food products reported some trans-fat content on the nutrition facts label and roughly a quarter of the food products claimed to contain no trans-fat on the front of the packaging. There was very low agreement among the trans-fat content reported in the nutrition facts label, claims of no trans-fat made on the packaging and the ingredient list.ConclusionsThere was low agreement among the different ways of reporting trans-fat, suggesting that it is not possible to rely on the nutrition facts label or no trans-fat claims printed on the packaging of Brazilian food products. Hence, the Brazilian legislation on food labels needs to change to improve the reliability of food labels and to help control the trans-fat intake of the population.
