<p>El objetivo del presente estudio fue evaluar el efecto de tres sistemas de alimentación sobre la respuesta productiva y el perfil de ácidos grasos en la carcasa de cuyes. Se emplearon 18 cuyes machos de 21 días de edad distribuidos aleatoriamente en tres grupos y alojados en jaulas galvanizadas. Los tratamientos fueron: T1, alfalfa verde; T2, alimentación mixta [alimento balanceado + alfalfa verde (10% del PV)]; y T3, alimentación integral (solo alimento balanceado). Se determinó la ganancia de peso, consumo de alimento y conversión alimenticia semanal. Los animales fueron sacrificados en el día 28 para evaluar el rendimiento de carcasa. Asimismo, se extrajo la grasa total para determinar el perfil de ácidos grasos mediante cromatografía de gases. Las variables de la respuesta productiva y el perfil de ácidos grasos de la carcasa de los animales experimentales fueron significativamente influenciados por los tratamientos dietarios (p&lt;0.05). T2 y T3 tuvieron mejor ganancia de peso, consumo de alimento, rendimiento de carcasa y menor conversión alimenticia que T1; sin embargo, tuvieron carcasas con mayor contenido de ácidos grasos omega-3, en particular ácido α-linolénico, y menor contenido de ácidos grasos omega-6, resultando en una menor relación de ácidos grasos n-6/n-3 y con menor contenido de grasa. Se concluye que la alfalfa (<em>Medicago sativa</em>) es una fuente de ácidos grasos n-3, particularmente de ácido α-linolénico, que puede mejorar el contenido de ácidos grasos n-3 de la carcasa del cuy.</p>

A experimentação animal apresenta uma grande importância para o desenvolvimento da ciência. O uso de camundongos em experimentos ocorre devido à semelhança destes animais com os seres humanos, fácil criação e manutenção e resposta experimental bastante rápida. Esses animais possuem as mesmas enzimas dessaturases e elongases que os humanos, por isso são usados em pesquisas envolvendo incorporação e síntese de ácidos graxos em tecidos. Os ácidos graxos da família ômega-3 e ômega-6 são de suma importância na dieta humana, pois estes não são sintetizados pela síntese de novo e são precursores dos ácidos graxos poli-insaturados de cadeia muito longa, como os ácidos eicosapentaenóico, docosahexaenóico e araquidônico. Estes desempenham funções importantes no organismo, como a síntese de eicosanóides que estão envolvidos diretamente no sistema imune e nas respostas inflamatórias. A razão entre o consumo de ácidos graxos n-6 e n-3 na dieta é um importante fator para determinar a ingestão adequada de ácidos graxos bem como prevenir o aparecimento de doenças. Este artigo tem como objetivo avaliar a incorporação de ácidos graxos em tecidos de animais e discutir a importância dos ácidos da família n-3 e seus metabólitos no sistema imunológico.

Introducción: Los lípidos de la leche materna (LM) están constituidos por diferentes ácidos grasos (AG) de vital importancia para el bebé. El contenido y tipo de AG de la leche humana puede variar según las reservas de grasa maternas. El propósito de este estudio fue determinar la relación entre el estado nutricional antropométrico de un grupo de mujeres lactantes y el perfil de AG de su LM madura. Material y métodos: El estudio fue descriptivo, transversal y correlacional. El estado nutricional se evaluó en 50 mujeres sanas, a quienes se les tomó una muestra de LM por extracción manual, con mínimo 1 mes de estar amamantando, residentes en Medellín, utilizando Índice de Masa Corporal (IMC), Circunferencia de Cintura (CC), Circunferencia de Brazo (CB) y Circunferencia de Muslo Medio (CMM). Las muestras de LM fueron analizadas por cromatografía de gases.Resultados: 26 (52 %) mujeres presentaron IMC entre sobrepeso y obesidad, 36 (72 %) CB > 27,1 cm, 32 (64 %) obesidad central según CC y 28 (56 %) presentó CMM > 50,1 cm. En cuanto a LM, los AG saturados arrojaron el mayor contenido 2,05 (0,77) g/100mL, y en los insaturados predominó el ácido linoléico 0,677 (0,31) g/100mL y sus isómeros 0,97 (0,58) g/100mL. No se encontró correlación significativa (p >0,05) entre IMC y el total de los AG saturados, monoinsaturados, poliinsaturados y grasa, aunque IMC se correlacionó (r = 0,281) con los AG saturados de cadena corta y media de la LM y de igual manera CB (r = 0,308) y CMM (r = 0,298). Conclusiones: No se encontró correlación entre IMC y perfil de AG.La LM analizada tiene mayor cantidad de AG omega 6 y menor omega 3 respecto a las recomendaciones de ingesta en lactantes y la relación insaturados/saturados fue similar a otros estudios.

Um fator diferencial na produção de bovinos é a compreensão da contribuição individual dos ácidos graxos e do papel dos lipídeos nos ruminantes, tanto na forma de análise (ácido graxo ou extrato etéreo), conceitos relacionados às características de ômega 3, ômega 6 e ácido linoleico conjugado na bio-hidrogenação, no metabolismo pós-absorção, bem como no conteúdo e composição dos ácidos graxos em relação à matéria seca dos alimentos. Sabe-se que diversos fatores podem afetar o teor, digestibilidade e degradabilidade das fibras presente na forragem, e o mesmo ocorre com os lipídeos. As diferenças entre os valores dos compostos presentes nos lipídeos podem ocorrer dependendo do ambiente, região do país ou fase de colheita e por isso, torna-se importante obter a análise da composição de ácidos graxos dos alimentos lipídicos, para que dessa maneira seja possível otimizar a utilização deste nutriente na dieta de animais ruminantes. Sendo assim, a proposta dessa revisão será trazer a discussão sobre o tema e abordar um entendimento sobre o conteúdo e composição de ácidos graxos dos ingredientes que compõem a dieta dos animais ruminantes, com ênfase na influência exercida no desempenho produtivo, imunonutrição, e no produto final (carne ou leite).

Eccado adalah produk olahan yang dibuat dari daging atau udang yang dicincang dengan penambahan tepung dan bumbu-bumbu. Pada umumnya Eccado diolah dari daging ayam, untuk menggantikan eccado ayam maka dicari sumber alternatif baru salah satunya digunakan ikan Gabus karena memiliki daging yang banyak, tebal dan putih. Potensi eccado ikan Gabus ini sangat tinggi baik aspek ekonomi juga kandungan gizinya karena mengandung omega 3 dan omega 6. Ikan Gabus bisa dimanfaatkan dengan cara langsung mengolahnya menjadi beberapa jenis makanan atau mengawetkannya melalui proses penggaraman dan pengeringan. Masih belum banyaknya diversifikasi bentuk pengolahan ikan hasil usaha budidaya khususnya ikan Gabus menjadi makanan olahan lain juga disebabkan karena masih minimnya informasi tentang teknologi pengolahan hasil perikanan. Permasalahan yang dihadapi mitra adalah : 1) Selama ini mitra belum mengetahui variasi tentang Teknologi Hasil Perikanan karena terbatasnya pengetahuan dan informasi yang diterima serta keterampilan yang dimiliki. 2) Mitra juga belum pernah mendapatkan pelatihan dan demonstrasi tentang pembuatan eccado dari ikan air tawar dalam hal ini ikan jenis ikan family Channidae Menurut SNI 7756 : 2013 dapat didefinisikan Eccado ikan merupakan produk olahan hasil perikanan dengan menggunakan lumatan daging ikan/udang dan atau surimi minimum 30%, tepung dan bahan-bahan lainnya, dibentuk dan dibungkus dengan kulit pangsit. Sedangkan Eccado merupakan salah satu jenis olahan fish jelly produk dengan menggunakan kulit kembang tahu yang berfungsi memberikan rasa yang khas.Tujuan kegiatan pengabdian kepada masyarakat ini untuk membantu mengatasi permasalahan yang dihadapi oleh masyarakat Pahandut Seberang l) Pendampingan teknologi diversifikasi pengolahan daging ikan menjadi eccado. 2) Promosi kegiatan Pahandut seberang sebagai lokasi wisata kuliner dengan kegiatan-kegiatan yang dapat meningkatkan kualitas kuliner dari ikan dan ekonomi masyarakat di sekitarnya.

AbstractLong-Chain Polyunsaturated Fatty Acid (LCPUFA) is essential throughout pregnancy, since deficiency of LPUFA may linked to obstetrical complications. This study aimed to investigate LCPUFA status in severe preeclampsia and preterm birth. A cross sectional study was conducted in 104 pregnant women, which divided into normal pregnancy, severe preeclampsia and preterm birth groups. Serum percentage and concentration of total LCPUFA, omega-3, alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), omega-6, linoleic acid (LA), and arachidonic acid (AA) were measured using gas chromatography/mass spectrometry. Receiver operating characteristic (ROC), bivariate and multivariate analysis were performed. Severe preeclampsia showed the highest concentration of total PUFA and the lowest DHA percentage, with significantly higher Omega-6/Omega-3 ratio (p = 0.004) and lower omega-3 index (p < 0.002) compared to control. Preterm birth showed the least omega-3 concentrations, with significantly low omega-6 derivates (LA (p = 0.014) and AA (p = 0.025)) compared to control. LCPUFA parameters have shown to increase the risk in both conditions, particularly ALA ≤ 53 µmol/L in preeclampsia with OR 5.44, 95%CI 1.16–25.42 and preterm birth with OR 4.68, 95%CI 1.52–14.38. These findings suggest that severe preeclampsia and preterm birth have an imbalance in LCPUFA status.

Alcoholic beverages like apple cider are considered functional beverages with several health benefits, when consumed in moderation, which are mainly attributed to their microbiota and the plethora of their bioactive compounds. Among them, bio-functional polar lipids (PL) have recently been found in apple cider, which despite low quantities, have exhibited strong anti-inflammatory and anti-platelet properties, while fermentation seems to affect the functionality of apple cider’s PL bioactives. The aim of the present study was to elaborate yeast strains isolated from the complex mixtures of apple surface and must yeasts for evaluating their effects on the anti-platelet functional properties of PL bioactives from their final fermented apple cider products. First, bio-functional PL were extracted and separated from the biomass of the different isolated apple surface/must yeast strains, and were further assessed for their anti-platelet potency against human platelet aggregation induced by the potent inflammatory and thrombotic mediator platelet-activating factor (PAF), or by a classic platelet agonist like adenosine diphopshate (ADP). Novel functional apple ciders were then produced from the fermentation of apple juice by elaborating the most bioactive and resilient yeast strains isolated from the apple must with optimum fermentation properties. PL bioactives extracted from these novel apple cider products were also further assessed for their anti-platelet properties against both the PAF and ADP pathways of human platelet aggregation. These novel cider products were found to contain PL bioactives with lower IC50 values (~40 μg) and thus increased anti-platelet potency against platelet aggregation induced by PAF and ADP. GC-MS analysis of the PL bioactives extracted from these novel apple ciders showed that apple cider PL bioactives are rich in monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA), such as the omega-6 linoleic acid (LA) and the omega-3 alpha linolenic acid (ALA), with favorably lower levels for their omega-6/omega-3 PUFA ratio, which further support the observed strong anti-platelet properties putative anti-inflammatory potency for the apple cider PL bioactives. However, further studies are needed in order to elucidate and fully characterize the apple yeast strains that can be utilized for increasing the anti-inflammatory, anti-platelet and cardioprotective functional properties of their fermented apple cider products.

Chronotype (CT) has been associated with predisposition to chronic noncommunicable diseases (CNCDs), such as diabetes mellitus and obesity. However, the effects of CT on individuals assisted by public health systems (PHSs) in middle-up economies are still poorly explored. The objective of this study was to evaluate the relationship between CT and clinical, sociobehavioral and nutritional aspects in adults assisted by a PHS in Brazil. This is a population-based cross-sectional study. The sample consisted of 380 individuals, selected through probabilistic sampling by clusters, in all health units in a city of approximately 100 thousand inhabitants. Data collection was performed during home visits, by means of general and nutritional interviews, anthropometric measurements and the Morningness–Eveningness Questionnaire (MEQ). Statistical analysis comprised chi-square test and principal component analysis (CPA) followed by Fisher’s discriminant analysis to determine aspects associated with each CT (morning, evening or intermediate). With the aim of explaining the variation in the CT scores, the consumption of micronutrients (corrected to the total energy intake) and other individual and sociodemographic variables were used as explanatory factors in the adjustment of a linear regression model. The morning group was characterized by older men, with less than eight years of schooling, with low body mass index (BMI) and with low intake of omega-6, omega-3, sodium, zinc, thiamine, pyridoxine and niacin. The evening group, on the other hand, was composed of younger individuals, with a high consumption of these same nutrients, with high BMI and a higher frequency of heart diseases (p < 0.05). It was concluded that most morning CT individuals were elderly thin males with lower consumption of omega-6 and -3, sodium, zinc, thiamine, pyridoxine and niacin, whereas evening individuals were younger, had higher BMI and had higher consumption of the studied micronutrients. The identification of circadian and behavioral risk groups can help to provide preventive and multidisciplinary health promotion measures.
