INTRODUCTION: Epilepsy is considered a health problem. 85% of patients are satisfactorily controlled with antiepileptic drugs (AEDs) and 15% have refractory seizures. The combination of omega 3 and omega 6 fatty acids (EquazenTM) can contribute to changes in ionic currents and to stabilization of neurotransmitter's function resulting in cell membrane equilibrium. These changes lead to potential seizure control. OBJECTIVE: To compare efficacy and safety in the treatment of refractory epilepsy with a supplement combining EPA, DHA (omega 3 fatty acids) and GLA (omega 6 fatty acids). METHODS: We reviewed patients from the Neurology Department of the Children's Hospital of Mexico who have refractory epilepsy, evaluating clinical characteristics of seizures, number of seizures and AEDs. 792 mg of EPA, DHA and GLA per day (6 capsules of EquazenTM) were administrated for four weeks in order to assess the frequency of seizures as well as tolerability and probable side effects. RESULTS: The study was conducted with a total of 13 patients with follow-up four weeks after the start of supplementation. We obtained a satisfactory clinical response with ≥ 80% decrease in the daily number of seizures in more than 60% of patient. The mean of number of seizures over all patients was reduced significantly from 26.61±37.2 to 5.92 daily. In addition a significant improvement in the neurocognitive capacity was observedin all patients. CONCLUSION: The co-adjuvant supplementation with EquazenTM may result in a reduction of the number of seizures in refractory epilepsy having in addition significant impact on neurocognitive aspects. To enhance the quality of life of epileptic patient supplementation with a specific combination of EPA, DHA and GLA should be reconsidered.

The interspecific ’hybrid striped bass’ is the result of cross breeding. Their offspring have got good chances of growth and tolerate extreme water temperatures and the content of dissolute oxygen more than their parents. Furthermore, they are more resistant to diseases. Therefore, the hybrid is perfectly suitable for intensive fishery production. Our experiment lasted for seven weeks. We analysed the indices of growth and production of the hybrid as the consequence of nurturing them with two feeds of high nutritive value during this period. We examined the content of fat and of fatty acids in the flesh of these fish. There were no considerable differences in terms of weight gain, feed conversion ratio and uneven growth between the two groups, while survival was less likely among the the fish which had consumed more fat. We demonstrated, examining the flesh of the individuals which had consumed feed containing lower fat content, that it was fattier and contained more dry matter than those that had been fed of higher fat content. Besides, the content of omega-3 and omega-6 fatty acids was higher in the fish that had consumed less lipids.

Penelitian ini bertujuan untuk mengetahui komponen asam lemak omega-3 dan omega-6 pada minyak ikan mas. Penelitian ini dilakukan di Laboratorium Pengolahan Pangan Fakultas Pertanian Universitas Katolik Santo Thomas, Medan. Pelaksanaan penelitian ini dilakukan pada bulan Agustus 2016 hingga Oktober 2016. Minyak ikan mas diperoleh dengan menggunakan proses rendering kering. Dari uji sifat fisika kimia diperoleh semakin besar nilai angka asam maka semakin rendah kualitas minyaknya, semakin kecil angka peroksida maka kualitas minyak semakin baik, bilangan iod yang tinggi menunjukkan bahwa minyak tersebut mengandung asam lemak tak jenuh yang banyak, semakin besar bilangan penyabunan yang dihasilkan maka minyak memiliki berat molekul yang lebih rendah. Hasil analisis minyak ikan dengan GC-MS didapat komposisi asam lemak sebagai berikut: asam lemak jenuh sebanyak 27,54%, asam lemak tidak jenuh tunggal sebanyak 43,92%, asam lemak tidak jenuh jamak sebanyak 21,25%. Asam lemak omega 3 sebanyak 2,83% yang terdiri dari asam linolenat 1,49%, asam eikosatrienoat 0,87%, asam eikosapentaenoat 0,11%, asam dekosaheksaenoat 0,36%, dan omega 6 sebanyak 17,36% yang terdiri dari asam linoleat 16,44%, asam arakhidonat 0,92%, Nilai gizi minyak ikan mas belum memenuhi komposisi ideal nilai gizi minyak ikan, dimana perbandingan ketiga jenis asam lemak belum memenuhi perbandingan 33,33% dan total penyimpangan sangat tinggi.   This study aimed to determine the components of omega-3 and omega-6 fatty acids in carp oil. This research was conducted at the Food Processing Laboratory of the Faculty of Agriculture, Santo Thomas Catholic University, Medan. The implementation of this research was conducted from August 2016 to October 2016. Carp oil was obtained using a dry rendering process. From the test of physical chemical properties obtained, the greater the value of the acid number, the lower the quality of the oil. It also showed that the smaller the peroxide number, the better the quality of the oil. The higher iodine number indicated that it contained many unsaturated fatty acids; therefore, the greater the saponification number the oil resulted, the lower molecular weight it obtained. The results of analysis of fish oil with GC-MS, showed the following fatty acid compositions: 27.54% saturated fatty acids, 43.92% monounsaturated fatty acids, and 21.25% plural unsaturated fatty acids. Omega-3 fatty acids were 2.83% consisting of 1.49% linolenic acid, 0.87% eicosapenoic acid, 0.11% eicosapentaenoic acid, 0.36% decosahexaenoic acid. It also resulted 17.36% omega-6 consisted of from linoleic acid 16.44%, arachidonic acid 0.92%. The nutritional value of goldfish oil did not meet the ideal composition of nutritional value of fish oil, where the ratio of the three types of fatty acids had not met the ratio of 33.33% and the total deviation was very high.

The aim of this study was to estimate the influence of diet supplemented with linseed rich additive under commercial name Vitalan on omega-fatty acids content in piglet meat. The main ingredient in Vitalan is extruded linseed, that contribute the diet is rich in omega-3 fatty acids. Piglets were divided in control and experimental group and reared to 33 kg of average live weight. Experimental group was fed the standard diet enriched with 2.5% of Vitalan. After the end of fattening period, the meat samples from both groups were analyzed for omega-3 and omega-6 fatty acids content in raw and oven- roasted meat. The ratio between omega-6 and omega-3 acids was established. Additionally, other parameters, such as weight gain, health and behaviour of piglets were observing during the study. The treatment with linseed enriched diet resulted in higher omega-3 acids content, which lowered ratio between omega-6 and omega-3 acids in meat, thus making it better for a human nutrition from a health perspective.

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.

Context. Several studies have shown a link between proinflammatory activity and the presence or deficit of some fatty acids. Inflammation is associated with several diseases including diabetes.Objective. To characterize and compare the fatty acids profiles in children with inaugural type 1 diabetes, diabetic children (at least 1 year after diagnosis), and healthy children.Design. Plasma fatty acids profiles in children with inaugural diabetes, children with noninaugural diabetes, and controls, all of whom were prepubescent with a BMI < 85th percentile, were evaluated.Results. Omega-3 fatty acid levels were higher in recently diagnosed subjects with diabetes than in controls. The ratio of omega-6/omega-3 fatty acids was higher in the control population. Omega-6 fatty acid levels were higher in the nonrecent diabetic subjects than in the children with recently diagnosed diabetes, and the levels were higher in the nonrecent diabetes group compared to the control group.Conclusion. Our findings showed higher levels of alpha-linolenic acid, EPA, and DHA, as well as mono- and polyunsaturated fatty acids, in diabetic children. These findings reinforce the importance of precocious nutritional attention and intervention in the treatment of diabetic children.
