Abstract
Aging is accompanied by a progressive decline in muscle mass and an increase in fat mass, which are detrimental changes associated with the development of health conditions such as type-2 diabetes mellitus or chronic low-grade inflammation. Although both exercise as well as nutritional interventions are known to be beneficial in counteracting those age-related changes, data to which extent untrained elderly people may benefit is still sparse. Therefore, a randomized, controlled, 12-week interventional trial was conducted in which 134 healthy untrained participants (96 women and 38 men, age 59.4 ± 5.6 years, body mass index (BMI) 28.4 ± 5.8 kg/m2) were allocated to one of four study groups: (1) control group with no intervention (CON); (2) 2×/week aerobic and resistance training only (EX); (3) exercise routine combined with dietary counseling in accordance with the guidelines of the German Nutrition Society (EXDC); (4) exercise routine combined with intake of 2 g/day oil from Calanus finmarchicus (EXCO). Body composition (bioelectrical impedance analysis), as well as markers of glucose metabolism and blood lipids, were analyzed at the beginning and the end of the study. The highest decreases in body fat were observed within the EXCO group (−1.70 ± 2.45 kg, p < 0.001), and the EXDC (−1.41 ± 2.13 kg, p = 0.008) group. Markers of glucose metabolism and blood lipids remained unchanged in all groups. Taken together results of this pilot study suggest that a combination of moderate exercise and intake of oil from Calanus finmarchicus or a healthy diet may promote fat loss in elderly untrained overweight participants.

Abstract
BACKGROUND AND OBJECTIVE Hyperlipidemia (HLP) is a leading cause for cardiovascular disease and atherosclerosis. Insufficient physical activity and unhealthy diet plays an important role in the progression of HLP. The present study was conducted to investigate the protective effect of 2 unconventional edible oils (purslane and garden cress) on hyperlipidemia. MATERIALS AND METHODS Diet high in fat and cholesterol was used as inducer of hyperlipidemia in rats for 5 weeks. Plasma and hepatic lipid profile were assessed. Plasma levels of malondialdehyde (MDA) as lipid peroxidation indicator was determined. Liver transaminases (AST and ALT) as liver function indicator and kidney function (creatinine and urea) were evaluated. RESULTS Results clarified significant elevation in plasma and liver lipid profiles, MDA, liver enzymes (AST and ALT) and kidney function (creatinine and urea) in hyperlipidemic control compared to normal control. Supplementation with purslane and garden cress seeds oils either in diet or oral showed significant improvement in all the studied parameters. CONCLUSION Purslane and garden cress oils investigated in the current study produced significant reduction and elevation in bad and good cholesterol, respectively in plasma. Also both oils reduced hepatic lipid accumulation effectively in hyperlipidemia model in rats. Oils administration reduced plasma malondialdehyde and improves liver and kidney functions.

Abstract
Batch anaerobic digestion was employed to investigate the performance of the floatable oil (FO) skimmed from food waste (FW) and the effect of different FO concentrations (5, 10, 20, 30, 40 and 50g/L) on biomethane production and system stability. FO and FO+FW were mono-digested and co-digested. The results showed that FO and FO+FW could be well anaerobically converted to biomethane in appropriate loads. For the mono-digestions of FO, the biomethane yield, TS and VS reduction achieved 607.7-846.9mL/g, 69.7-89% and 84.5-92.8%, respectively, when FO concentration was 5-40g/L. But the mono-digestion appeared instability when FO concentration was 50g/L. For the co-digestions of FW+FO, TS and VS reductions reached 70.7-86.1% and 87.5-91.4%, respectively, when FO concentration was 5-30g/L. However, the inhibition occurred when FO concentrations increased to 40-50g/L. The maximal FO loads of 40g/L and 30g/L were hence suggested for efficient mono-digestions and co-digestions of FO and FO+FW.

Abstract
The omega-3 polyunsaturated fatty acid, docosahexaenoic acid (DHA, 22:6n-3) has been previously shown to facilitate some of the vital functions of astrocytes. Since some dietary oils contain alpha-linolenic acid (ALA, 18:3n-3), which is a precursor of DHA, we examined their effect on astrocyte development. Fatty acids (FAs) were isolated from commonly used oils and their compositions were determined by GLC. FAs from three oils, viz. coconut, mustard and linseed were studied for their effect on astrocyte morphology. Parallel studies were conducted with FAs from the same oils after heating for 72 h. Unlike coconut oil, FAs from mustard and linseed, both heated and raw, caused significant morphogenesis of astrocytes in culture. ss-AR binding was also substantially increased in astrocytes treated with FAs from raw mustard and linseed oils as compared to astrocytes grown in normal medium. The expression profile of the isoforms of GFAP showed that astrocyte maturation by FAs of mustard and linseed oil was associated with appearance of acidic variants of GFAP and disappearance of some neutral isoforms similar to that observed in cultures grown in serum containing medium or in the presence of DHA. Taken together, the study highlights the contribution of specific dietary oils in facilitating astrocyte development that can have potential impact on human health.

Abstract
A central role in the oxidative development of atherosclerotic lesions has been ascribed to the peroxidation of plasma low-density lipoprotein (LDL). Dietary supplementation with virgin olive oils increases the total plasma antioxidant status and the resistance of low-density lipoprotein to ex vivo oxidation. We have studied the effects of some dietary non-flavonoid phenols from Olea europaea L., both in purified form or in complex mixtures obtained by biotransformation of olive leaf extracts, on the LDL oxidation induced by Cu2+ ions. Cu2+-Induced LDL oxidation is inhibited by oleuropein and hydroxytyrosol in the initiation phase of the reaction at concentrations of phenols higher than that of Cu2+ ions. Interestingly, at lower concentration, both phenols anticipated the initiation process of LDL oxidation, thus exerting prooxidant capacities. Although similar effects are already described for flavonoids, such as quercetin, rutin, and apigenin, it is the first time that a prooxidant effect of dietary non-flavonoid phenols, such as oleuropein and hydroxytyrosol, on the LDL oxidation is reported. Our results show that a net effect of oleuropein and hydroxytyrosol on Cu2+-induced LDL peroxidation is determined by a balance of their pro- and antioxidant capacities. It is worth to underline that, during Cu2+-induced LDL oxidation in the presence of bioreactor eluates, we have evidence of a synergistic effect among phenolic compounds that enhance their antioxidant capacities so avoiding the prooxidant effects.

Abstract
Cases of allergy to the oils of groundnut, sunflower, soya and sesame have been described in the literature. In parallel, other authors have affirmed that these oils are not allergenic. The objective of this article is to make the point on this question, to cite the procedures to which the seeds are submitted to extract the oil, to remember that the oils are not composed only of triglycerides and to describe the results of our work. Allergy of oils is a subject that is constantly submitted to controversy and the bibliography does not cease to give contradictory examples. This may be explained by the variations in extraction procedures used by the manufactures, as well as by the conditions of extraction of the proteins in the laboratory.

Abstract
Lamb pregastric esterase, immobilized by physical adsorption on microporous polypropylene in a hollow fiber reactor, has been employed to effect the continuous hydrolysis of the triglycerides in butter oil. Experimental data were obtained at temperatures from 35 to 45 degrees C and pH values from 5.5 to 6.5. The overall rate of hydrolysis was fastest at 40 degrees C and a pH of 6.0. Nonlinear regression methods were employed to determine the kinetic parameters of rate expressions based on a generic Ping-Pong Bi Bi mechanism. The best nonlinear fit of the data was consistent with a mechanism that assumes that acylation of the enzyme is the rate-limiting step in the hydrolysis reaction.

Abstract
It was produced plant-derived product, an omega-3 acid-enriched substrate (64%). In our study we tested the influence of this preparation, which is supposed a membrane-modifying agent, on the processes of damage to the isolated heart under conditions of ischemia-reperfusion. Animals took this substrate as nutrient addition to usually everyday diet. We assumed disorders in cardiodynamics and contractile functions of the myocardium (we measured a perfusion pressure in coronary vessel, left ventricular pressure and dp/dt) and in structure of cardiomyocytes. All mentioned parameters was much better after ischemia-reperfusion in hearts from animals which took an omega-3 acid-enriched substrate in course of 4 week before experiments than in hearts from control animals. Conclusions. Omega-3 polyunsaturated acids exert protective effect on functioning and structure of the isolated rat heart during ischemia-reperfusion.

Abstract
A calf pregastric esterase immobilized in a hollow-fiber reactor was employed to hydrolyze milkfat, thereby producing a lipolyzed butteroil. The reaction kinetics can be modeled by a two-parameter model of the general Michaelis-Menten form based on a ping-pong bi-bi mechanism; the rate of enzyme deactivation can be modeled as a first-order reaction. The initial concentration of accessible glyceride bonds, [G](O), was estimated by complete saponification of the substrate butteroil as 2400 mM. An extra sum of squares test indicated that not only the parameters of the kinetic generalized Michaelis-Menten model, but also the deactivation-rate constant varied significantly with pH. The optimum pH, for lypolysis is near 6.0 at a temperature of 40 degrees C because at this pH the rate of deactivation of the esterase is minimized.

Abstract
Lipids are one of the main dietary components that serve several functions in foods and nutrition. They could be endogenous or deliberately included in food. The basic molecules of lipids undergo different chemical reactions during refining, processing and storage. Some of these chemical reactions enhance the usage and functionality of food lipids. This chapter discusses the chemical changes of lipids during various processing operations. Specific changes in the minor constituents of lipids are also included.

Abstract
Flaxseed has been used as an edible grain in different parts of the world since ancient times. However, use of flaxseed oil has been limited due to its high content of polyunsaturated fatty acids. Nonetheless, alpha-linolenic acid, dietary fiber and lignans of flaxseed have regained attention. New varieties of flaxseed containing low levels of alpha-linolenic acid are available for edible oil extraction. Use of whole flaxseed in foods provides a means to utilise all of its nutrients and require minimum processing steps. However, the presence of cyanogenic glucosides and diglucosides in the seeds is a concern as they may release cyanide upon hydrolysis. In addition, the polyunsaturated fatty acids may undergo thermal or autooxidation when exposed to air or high temperatures that are used in food preparation. Studies todate on oxidation products of intact flaxseed lipids have not shown any harmful effects when flaxseed is included, up to 28%, in the baked products. Furthermore, cyanide levels produced as a result of autolysis are below the harmful limits to humans. However, the meals left after oil extraction require detoxification but, by solvent extraction, to reduce the harmful effects of cyanide when used in animal rations. Flaxseed meal is a good source of proteins; these could be isolated by complexation with sodium hexametaphosphate without changing their nutritional value or composition. In addition, the effect of germination on proteins, lipids, cyanogenic glycosides, and other minor constituents of flaxseed is discussed.
