A profile of free fatty acid (FFA) specificity in Acanthamoeba castellanii mitochondrial uncoupling is described. The FFA uncoupling specificity was observed as different abilities to stimulate resting respiration, to decrease resting membrane potential, and to decrease oxidative phosphorylation efficiency. Tested unsaturated FFA (C18-20) were more effective as uncouplers and protonophores when compared to tested saturated FFA (C8-18), with palmitic acid (C16:0) as the most active. As FFA efficiency in mitochondrial uncoupling is related to physiological changes of fatty acid composition (and thereby FFA availability) during growth of amoeba cells, it could be a way to regulate the activity of an uncoupling protein and thereby the efficiency of oxidative phosphorylation during a cell life of this unicellular organism.

Background: A fatty acid (FA) is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated. Recently, the role of FA and particularly omega-3 and -6 has emerged as cardiovascular risk factor in the literature. The aim of our study was to establish reference values for these FA and to compare them with data obtained in a population of acute myocardial infarction (AMI) patients. Materials and methods: Hundred thirty five healthy subjects (59.38 ± 27.12 yo, 75 men) were selected as reference population. We also evaluated FA in thirty three patients (55 ± 9 yo, 23 men) admitted in the Emergency Department of our Institution for AMI. The fasting whole blood was drawn in vacutainer containing EDTA. Before analysis, samples were washed and transmethylated. We performed the quantification of different FA by gas chromatography associated with flame ionisation detector (GCFID). Results: We obtained results in control healthy patients to be used as reference values. In the AMI group, levels of omega-6 were significantly higher (p<0.05) for C18:2n6 and C18:3n6 than the reference population and omega-3 values were significantly lower (p<0.01) compared to reference value for C22:6n3. The omega-3 index was lower and the ratio omega-6/omega-3 was higher in AMI group compared to reference values. Conclusions: We have established reference value for FA and have compared these values with the results obtained in AMI population. FA determination is a new tool we are able to use and to process in our laboratory which can help the clinician to screen patients with the highest cardiovascular risks because of the implication of FA in the etiopathogeny of atherosclerosis.

Recent observations revealed an increased abundance of the harbour porpoise in the southern part of the North Sea. Concomitant to sightings of living individuals, the number of stranded porpoises displaying lesions linked to fishing nets has also increased this last decade. The increased abundance of porpoises together with the increase in numbers of bycaught animals raised the question of possible competition between porpoises and fishermen in the North Sea. Therefore, a detailed view on harbour porpoise trophic ecology in this region is crucial for their conservation. Stomachs of the washed ashore porpoises were often empty and provided limited information on their recent diet. Another way of looking into the diet of marine mammals is the analysis of blubber. Stable isotopes ratio (d13C and d15N, SI) and fatty acid composition (20 fatty acids, FA) were analyzed in muscle and blubber of 10 freshly stranded harbour porpoises and in 60 potential prey fish from 10 species collected in the North Sea. The SI ratio and FA composition of these fish enabled a clear classification in different trophic levels and different trophic niches. The FA composition was very similar between harbour porpoise blubber and demersal fish, underlining a preferential predation on that resource for the porpoises investigated. A bias might exist for the porpoises: most of the animals were juveniles, and washed ashore during spring. Porpoises might display other feeding habits in other life stages, other periods of the year. These preliminary results however indicate the enhanced accuracy of crossing these biomarker approaches.

The fatty acid composition of hump fat stemming from 43 Algerian camels (Camelus dromedarius), 1 to 13 years old, both sexes, belonging to Sahraoui and Tergui breeds, was determined. Saturated fatty acids (SFA) represented 64.4% (weight basis) of total fatty acids, while the monounsaturated (MFA) and polyunsaturated (PUFA) fractions accounted for 33.1 and 2.5%, respectively. The main saturated fatty acids, namely palmitic and stearic acids represented 49.6% and 38.8 % of SFA (31.5% and 25.5% of total fatty acids). Unsaturated fatty acids (UFA) were mainly represented by oleic acid, 78.1% of MFA (25.9% of total fatty acids), linoleic acid which accounted for 88.5% of omega 6 (1.17% of total fatty acids) and linolenic acid accounting for 63.9% of ω3 (0.42% out of total fatty acids). SFA/PUFA was 0.039 and ω6/ω3, 2.81. The levels of fatty acids, SFA and MFA were significantly higher in females, while the contents in ω6, ω3, CLA, PUFA, as well as the PUFA / SFA and ω6/ω3 ratio were comparable in relation to both sexes. When reported to the breeds, the contents in MFA, PUFA and ω6 was higher in Sahraoui, as the ω6/ω3 ratio was. The percentage of SFA, however, was higher in Tergui. [less ▲]

PURPOSE OF REVIEW: Non-alcoholic steatohepatitis is a liver disease characterized by steatosis and steatohepatitis in subjects whose alcohol consumption is negligible. The primary form is associated with insulin resistance whereas secondary non-alcoholic steatohepatitis occurs notably during total parenteral nutrition or in patients in the intensive care unit. This review is mainly focused on recent developments in the understanding of the pathogenesis of this disease. RECENT FINDING: Pathogenesis involves the direct role of fatty acids in liver injury, oxidative stress, cytokines, genetic susceptibility or mitochondrial dysfunction. An increased delivery of free fatty acids to the liver contributes to the first hit, originating liver steatosis. The process may undergo a second hit, characterized by inflammation and hepatocellular degeneration. Mitochondrial dysfunction plays a key role by leading to abnormal generation of reactive oxygen species, which cause lipid peroxidation. The peroxidation products and cytokines favor progression from steatohepatitis to fibrosis. Fatty liver disease may also be encountered in the intensive care unit in patients receiving parenteral nutrition. However, an adapted glucose-lipid ratio as source of non-protein calories prevents the development of fatty liver. Moreover, recent evidence suggests the importance of the type of lipid infused (structured lipid emulsion or fish oils). The acute phase response associated with severe disease can also lead to the development of fatty liver in spite of adequate nutritional support. SUMMARY: The pathogenesis of non-alcoholic steatohepatitis is multifactorial, but there is growing evidence that mitochondrial dysfunction always plays a key role. Adapted nutrition may prevent in part fatty liver in the intensive care unit. [less ▲]

Early diagnosis of structural damages or machinery malfunctions allows to reduce the maintenance cost of systems and to increase their reliability and safety. This paper addresses the damage detection problem by statistical analysis on output-only measurements of structures. The developed method is based on subspace analysis of the Hankel matrices constructed by vibration measurement data. The column active subspace of the Hankel matrix defined by the first principal components is orthonormal to the column null-subspace defined by the remaining principal components. The residue in the orthonormality relation obtained from different data sets may be used to detect structural damages. It is illustrated that this null-space-based method constitutes an enhancement of the classical damage detection method based on principal component analysis (PCA). Several damage indicators are proposed to characterize the resulting residue matrices. The method is first illustrated on a numerical example and then, it is applied to vibration fatigue testing of a street-lighting device. Because of its simplicity and efficiency, the proposed algorithm is expected to be suitable for continuous on-line health monitoring of structures in practical situations. [less ▲]
