Patients with multiple sclerosis (MS) are characterized by, among other symptoms, impaired functional capacity and walking difficulties. Polyunsaturated fatty acids (PUFAs) have been found to improve MS patients’ clinical outcomes; however, their effect on other parameters associated with daily living activities need further investigation. The current study aimed to examine the effect of a 24-month supplementation with a cocktail dietary supplement formula, the NeuroaspisTM PLP10, containing specific omega-3 and omega-6 PUFAs and specific antioxidant vitamins on gait and functional capacity parameters of patients with MS. Fifty-one relapsing-remitting MS (RRMS) patients with low disability scores (age: 38.4 ± 7.1 years; 30 female) were randomized 1:1 to receive either a 20 mL daily dose of the dietary formula containing a mixture of omega-3 and omega-6 PUFAs (12,150 mg), vitamin A (0.6 mg), vitamin E (22 mg), and γ-tocopherol (760 mg), the OMEGA group (n = 27; age: 39 ± 8.3 years), or 20 mL placebo containing virgin olive oil, the placebo group (n = 24; age: 37.8 ± 5.3 years). The mean ± SD (standard deviation) Expanded Disability Status Scale (EDSS) score for the placebo group was 2.36 and for the OMEGA group 2.22. All enrolled patients in the study were on Interferon-b treatment. Spatiotemporal gait parameters and gait deviation index (GDI) were assessed using a motion capture system. Functional capacity was examined using various functional tests such as the six-minute walk test (6MWT), two sit-to-stand tests (STS-5 and STS-60), and the Timed Up and Go test (TUG). Isometric handgrip strength was assessed by a dynamometer. Leg strength was assessed using an isokinetic dynamometer. All assessments were performed at baseline and at 12 and 24 months of supplementation. A total of 36 patients completed the study (18 from each group). Six patients from the placebo group and 9 patients from the OMEGA group dropped out from the study or were lost to follow-up. The dietary supplement significantly improved the single support time and the step and stride time (p < 0.05), both spatiotemporal gait parameters. In addition, while GDI of the placebo group decreased by about 10% at 24 months, it increased by about 4% in the OMEGA group (p < 0.05). Moreover, performance in the STS-60 test improved in the OMEGA group (p < 0.05) and there was a tendency for improvement in the 6MWT and TUG tests. Long-term supplementation with high dosages of omega-3 and omega-6 PUFAs (compared to previous published clinical studies using PUFAs) and specific antioxidant vitamins improved some functional capacity and gait parameters in RRMS patients.

The main goal of the present study was to determine optimal conditions for the extraction of oil with high added value by cold pressing technique. Namely the feeding conditions of the Opuntia ficus-indica (L.) Mill. (OFI) seeds, as well as the definition of the manipulable variables of the Kern-Kraft 20 press were specified. These specifications combine HAZOP (Hazard and Operability) analysis and experience plan to find out correlation between yield and oil quality with the pressure, temperature, nozzle diameter, residence time, pressing speed while considering high hardness level of the seed under study. The seed oil extracted according to the proposed approach was highly unsaturated where linoleic acid is the main fatty acids (60.42 % of total fatty acids), followed by oleic acid (21.65 %), palmitic acid (12.24 %), and stearic acid (3.88 %), respectively. Furthermore, it is worth mentioning that beta-sitosterol and gamma-tocopherol were the principal components of sterols and tocopherols representing 67.56 % of total sterols and 330 mg.kg-1 of total tocopherols. The proposed approach applied to prickly pear seeds had preserved the tocopherol fraction (796.70 mg.kg-1 of total tocopherols) about two times more than other cold-pressed seed oils approaches. Based on trial-and-error conditions, no additional operating problem even has been reported with a seed of high level of hardness. Seed should be introduced with a humidity level of 10 % without grinding. Moreover, no heating should be supplied and an optimal pressing speed of 30 and a nozzle diameter of 15 mm.

Food manufacturers are eager to develop functional foods by adding healthy polyunsaturated fatty acids to new products, but they must first develop a natural antioxidant capable of protecting the lipids in an emulsion. Researchers are using AI to help them more quickly identify protein peptides that can act as antioxidants. Synergistic phospholipids and phenolic compounds from plant extracts are other natural antioxidants researchers are exploring.

Abstract This study focuses on yields, chemical quality, composition, and the stability of the fatty acids of the oil extracted from Opuntia ficus indica seeds, collected from the eastern region of Morocco, regardless of the temperature and the extraction method used. The results of this study reveal that prickly pear is a rich source of oil. The obtained oil yields varied from 12.49%±0.09 for the mechanical extraction, 11.46±0.10 for the chemical extraction, and 10.52%±0.09 for the maceration. The main fatty acids found in O. Ficus indica are linoleic acid 75.80%±0.10 (Chemical), 74.07%±0.14 (Maceration) and 71.59%±0.14 (Mechanical), and palmitic acid 17.32%±0.02 (Chemical) 22.419% ±0.06 (Maceration) and 26.58% ±0.00 (Mechanical). So the oil of prickly pear could be classified as a linoleic. Among the Tocopherols founded, a high value of b-tocopherol has been detected in the mechanical extraction with 502.04±0,76 mg/kg followed by the chemical and the maceration extraction with (430.12±0.61mg/kg, 315.47± 0.96 mg/kg) respectively. The findings of the present study reveal that the oil of O. ficus indica could be used in cosmetics and pharmacological products.

Objective. Omega–3 polyunsaturated fatty acids (PUFAs) were tested in adolescent depression and in several neurodevelopmental disorders with partial success. Anorexia nervosa (AN) is characterised by deficiencies in fatty food intake and frequent comorbidity, including depressive and cognitive symptoms. Thus supplementation with PUFAs may be beneficial in this group of patients. The aim of the study was to assess whether PUFAs as an add-on treatment is associated with better improvement of body mass index (BMI) and psychopathological symptoms than placebo in patients with AN. Method. 61 female adolescent inpatients with AN were randomly allocated to omega–3 PUFAs supplementation or placebo for 10 weeks. Patients also participated in the behavioural programme and eclectic psychotherapy (treatment as usual, TAU). At baseline and follow-up visits, patients’ BMI and psychopathology were assessed with Clinical Global Impression Scale (CGI), Patient Global Impression Scale (PGI), and Eating Attitude Test (EAT-26). Results. After 10 weeks, both groups showed improvement in all parameters. Improvement in CGI scores was observed greater in placebo vs. PUFA-s group (p = 0.015) while other differences were not statistically significant. Omega–3 PUFAs supplementation appears not to be effective as an add-on treatment in inpatient adolescent girls with anorexia nervosa. Conclusions. The results should be analysed with caution due to small sample size and heterogeneity in TAU. As the TAU turned out to be highly effective, additional therapeutic effect of PUFA might not be visible. Nevertheless, that does not explain the tendency for better improvement in the placebo group.
