Аннотация: In vitro experiments proved the usefulness of electron paramagnetic resonance (EPR) spectrometry for detecting detonation nanodiamonds (NDs) in samples of biomaterials (blood and homogenates of organs of mice). A characteristic EPR signal (g = 2.003, Delta H similar or equal to 10 G) was detected in biomaterials containing NDs, and its intensity linearly increased at nanoparticle concentrations of between 1.6 and 200 mu g/ml. In vivo experiments demonstrated that EPR spectrometry was effective for monitoring the inter-organ distribution of NDs intravenously injected to mice. In 2.5 h after the injection of NDs, the nanoparticles mainly accumulated in the lungs and liver of the animals - about 25 and 20%, respectively, of the initially injected NDs. The amounts of NDs accumulated in the heart and kidneys were considerably lower. Also, EPR spectrometry did not detect NDs in the blood, spleen, brain, and femoral muscles of mice. Ten days after injection, EPR spectrometry detected redistribution of NDs in mice. The amounts of nanoparticles decreased approximately by a factor of 3.5 in the lungs and increased almost by a factor of 3 in the liver; NDs were detected in the spleen. This study suggests ways to use EPR spectrometry to study the distribution, accumulation, and elimination of detonation NDs injected into laboratory animals.

Заглавие : Time-dependent trends of artificial radionuclides in biota of the Yenisei River (Siberia, Russia)
Место публикации : J. Environ. Radioact.: Elsevier Ltd, 2019. - Vol. 208-209. - Ст.106028. - ISSN 0265931X (ISSN) , DOI 10.1016/j.jenvrad.2019.106028
Аннотация: We investigated time-dependent trends of artificial radionuclides in aquatic moss, zoobenthos (amphipods and caddisfly larvae), and three abundant wild fish species (Northern pike, Arctic grayling, and Siberian dace) inhabiting the Yenisei River in the vicinity of the radioactive discharge site in 2007–2015, in a period before and after the shutdown of the last nuclear reactor plant at the Mining-and-Chemical Combine (MCC), which occurred in 2010. From our research, we learned that concentrations of short-lived radionuclides, whose discharges to the Yenisei either stopped or declined after the shutdown of the reactor plant at the MCC (24Na, 46Sc,51Cr, 54Mn, 58Co, 59Fe, 60Co, 65Zn, 103Ru, 141,144Ce, 152,154Eu, 239Np), decreased in biota samples as well. The ecological half-life (EHL) of 65Zn (0.4–0.7 y) was similar to the physical half-life of this isotope, the EHLs of 60Co (1.2–2.1 y) and 152Eu (1.8 y) were shorter than the physical half-lives of these isotopes. Concentration of 137Cs did not decrease significantly in biota of the Yenisei after the shutdown of the last reactor plant because the discharges of this radionuclide to the Yenisei continued at the same level. On a longer-term scale (since 1973 and since 1991), concentration of 137Cs in fish muscle had significantly decreased, following the decrease in annual discharges of this radionuclide to the Yenisei, and the EHL of 137Cs was estimated as 6.5–12.8 y. Statistically significant correlation with annual discharges of 137Cs was revealed for the concentration of this radionuclide in grayling (whole bodies and muscle); dace (muscle), and amphipods. Despite their ability to accumulate high concentrations of 137Cs, aquatic moss and caddisfly larvae (analyzed together with their stony casings) were not sensitive to interannual fluctuations in the releases of this radionuclide to the Yenisei. Among the analyzed fish species of the Yenisei, the highest activity concentration of 137Cs was revealed in pike (body and muscle), indicating biomagnification of this radionuclide in the top level of the trophic chain. © 2019 Elsevier Ltd

Аннотация: For the first time, seasonal changes in the content of total lipids (TLs) and phospholipids (PLs) were studied in fodder plants growing in Central Yakutia-a perennial cereal, smooth brome (Bromopsis inermis L.), and an annual cereal, common oat (Avena sativa L.). Both species have concentrated TLs and PLs in autumn under cold hardening. In addition, a significant increase in the content of fatty acids (FAs) of B. inermis was observed during the autumn decrease in temperature. The Yakutian horses, which fed on cereals enriched with nutrients preserved by natural cold (green cryo-fodder), accumulated significant amounts of 18:2n-6 and 18:3n-3, the total content of which in cereals was 75% of the total FA content. We found differences in the distribution of these two FAs in different tissues of the horses. Thus, liver was rich in 18:2n-6, while muscle and adipose tissues accumulated mainly 18:3n-3. Such a distribution may indicate different roles of these FAs in the metabolism of the horses. According to FA content, meat of the Yakutian horses is a valuable dietary product.

Аннотация: In several Russian northern lakes and rivers, Arctic cisco Coregonus autumnalis, least cisco C. sardinella, peled C. peled, tugun C. tugun, broad whitefish C. nasus, whitefish C. lavaretus and vendace C. albula were sampled in periods of officially permitted commercial fishery. Special attention was paid to contents (mg g(-1) of wet weight) of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in muscle tissues (filets), which are essential for human nutrition. The highest values of EPA + DHA content in semi-anadromous fish and freshwater fish were recorded for C. autumnalis from the Yenisei River, 17.60 mg g(-1) wet weight, and for C. lavaretus from the Sobachye Lake, 16.61 mg g(-1) wet weight, respectively. Intra-genus variations of EPA + DHA contents of Coregonus species were from 1.87 to 17.60 mg g(-1) wet weight. Since the congeneric species were genetically close to each other, the variations in EPA and DHA contents were thought to be caused primarily by ecological factors: migrational capability, type of feeding and trophic status of aquatic ecosystems. In general, the majority of studied species appeared to be of a high nutritive value for humans, although unfavorable environmental conditions could considerably diminish this value.

Заглавие : Triploidy does not decrease contents of eicosapentaenoic and docosahexaenoic acids in filets of pink salmon Oncorhynchus gorbuscha
Место публикации : Food Chem. - 2017. - Vol. 216. - С. 66-69. - ISSN 03088146 (ISSN) , DOI 10.1016/j.foodchem.2016.08.021

Аннотация: Triploid fish has become an important item of commercial aquaculture, but data on its fatty acid (FA) composition are still controversial, especially regarding essential polyunsaturated fatty acids, eicosapentaenoic acid (20:5n-3, EPA) and docosahexaenoic acid (22:6n-3, DHA). We studied FA composition and content of diploid and triploid pink salmon Oncorhynchus gorbuscha, reared in aquaculture in a bay of the White Sea (Russia). FA composition, measured as percentages of total FA of triploids and immature diploid females significantly differed from that of mature diploid fish. Specifically, mature diploids had higher percentage of EPA and DHA in their muscle tissue (filets) compared to that of triploids and immature diploid females. Nevertheless, the contents of EPA and DHA per mass of the filets in diploid and triploid specimens were similar. Thus, no special efforts are needed to improve EPA and DHA contents in filets of triploids. © 2016 Elsevier Ltd

Ключевые слова (''Своб.индексиров.''): fatty acids--aquaculture--food chain--bioaccumulation
Аннотация: Two fish species reared in aquaculture (pink salmon Oncorhynchus gorbuscha and whitefish Coregonus lavaretus) and ten fish species from natural habitats (whitefish C. lavaretus, tugun Coregonus tugun, broad whitefish Coregonus nasus, least cisco Coregonus sardinella, vendace Coregonus albula, boganid charr Salvelinus boganidae, charr Salvelinus alpinus complex, northern pike Esox lucius, sharp-snouted lenok Brachymystax lenok, and taimen Hucho taimen) have been studied. The content of two long-chain polyunsaturated omega-3 fatty acids (PUFAs), eicosapentaenoic acid (20:5n-3, EPA) and docosahexaenoic acid (22:6n-3, DHA), in the muscle tissue of the fish and in their food (intestine contents) are compared. In the aquacultures of whitefish and pink salmon, the total content of EPA and DHA is significantly higher in feed than in the muscle tissue of the fish, which indicates losses of PUFA in the two-link food chain of the aquaculture during their transfer to the upper trophic level. EPA and DHA losses in aquaculture, which are confirmed by numerous literature data, mean an inefficient usage of the available sources of PUFAs and the aggravation of the global deficit of these biochemicals in the human diet. A study of natural fish populations reveals the accumulation of EPA and DHA in their biomass compared to food in many cases, although opposite phenomena are also observed. An assumption on the presence of an optimal, physiologically adequate species-specific level of PUFA in the fish muscle tissue has been made based on our data and literature data. If the level of PUFAs in the muscles is lower than optimal, their accumulation (bioaccumulation) from food and/or de novo synthesis are observed. When the optimal level is exceeded, the content of EPA and DHA in biomass approaches maximum species-specific values; however, part of these PUFAs entering from food is not digested or is catabolized. According to the obtained data, the species of the order Salmoniformes have an optimal level of 2 to 6 mg/g of wet weight. It has been found that in aquaculture approaching to maximum values of EPA + DHA content was accompanied by their losses (scattering) in the food chains, while in natural ecosystems the maximum values of PUFA content in the fish biomass are achieved by their accumulation from the lower trophic level. Boganid charr S. boganidae had the highest content of EPA + DHA in the muscle tissue among all known fish species (32.78 mg/g of wet weight).

Аннотация: Fish are recognized as the main source of physiologically important omega-3 long-chain polyunsaturated fatty acids, namely, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), for human nutrition. However, muscle tissue contents of these fatty acids in diverse fish species, i.e., their nutritive value for humans, varied within two orders of magnitude. We reviewed contents of EPA and DHA, measured by similar methods using an internal standard during chromatography as mg per g of wet mass in 172 fish species belonging to 16 orders, to evaluate probable variations in phylogenetic and ecological drivers. EPA + DHA content varied from 25.6 mg g(-1) of wet mass (Sardinops sagax) to 0.12 mg g(-1) (Gymnura spp.). Multidimensional redundancy analysis revealed that among phylogenetic, ecomorphological and abiotic environmental factors, the highest proportion of variation contribution belonged to the shared contribution of sets of phylogenetic and ecomorphological factors. Specifically, the highest values of EPA + DHA content were characteristic of fish belonging to the orders Clupeiformes or Salmoniformes, were pelagic fast swimmers, ate zooplankton and inhabited marine waters or migrated from fresh to marine waters (anadromous migrations). High EPA and DHA content in muscle tissues of the above species appeared to be a metabolic adaptation for fast continuous swimming. In contrast to common beliefs, our meta-analysis did not support the significant influence of higher trophic levels (piscivory) and cold environments (homeoviscous adaptation) on EPA and DHA content in fish. However, many causes of high and low levels of physiologically important fatty acids in certain fish species remained unexplained and require evaluation in future studies.

Аннотация: Long-chain polyunsaturated fatty acids of n-3 family (n-3 LC PUFAs) are physiologically essential compounds required for normal growth and development of animals, including humans. The ability of fish species to synthesize n-3 LC PUFAs varies significantly across different trophic levels. We have studied fatty acid (FA) content (mg/g of wet weight) and level (% of total FAs) in the brain, liver, heart, intestine, female and male gonads, muscle, and adipose tissues of commercially important wild freshwater Baikal grayling. Additionally, FA content and level of Baikal grayling juveniles have been studied. In all tissues of Baikal grayling, some LC PUFAs, namely, 24:5n-3 and 24:6n-3 (C24 PUFAs), have been found. These FAs are the intermediate products in the synthesis of docosahexaenoic acid (DHA, 22:6n-3) by the Sprecher pathway. The levels of C24 PUFAs in tissues differed significantly: the highest levels of C24 PUFAs were found in adipose tissue and the lowest values in the gonads of females, liver, brain, and head of juveniles. According to the dynamics of DHA and C24 PUFAs, the maximum rate of DHA synthesis is achieved in brain of Baikal grayling, while the lowest rate of DHA synthesis probably occurs in adipose tissue. Although all studied tissues had differences in the number of FAs and their levels, 16:0, 18:1n-9, 16:1n-7, 20:5n-3, and DHA dominated. Male gonads contained an extremely high level of furan FAs - presumably beneficial substances for human health. Additionally, the nutritional value of the tissues of Baikal grayling as a source of n-3 LC PUFAs for humans has been estimated.

Аннотация: Fatty acids (FA) of muscle tissue of Salvelinus species and its forms, S. alpinus, S. boganidae, S. drjagini, and S. fontinalis, from six Russian lakes and two aquacultures, were analyzed. Considerable variations in FA compositions and contents were found, including contents of eicosapentaenoic and docosahexaenoic acids (EPA and DHA), which are important indicators of fish nutritive value for humans. As found, contents of EPA+DHA (mg center dot g(-1) wet weight) in muscle tissue of Salvelinus species and forms varied more than tenfold. These differences were supposed to be primarily determined by phylogenetic factors, rather than ecological factors, including food. Two species, S. boganidae and S. drjagini, had the highest EPA+DHA contents in their biomass and thereby could be recommended as promising species for aquaculture to obtain production with especially high nutritive value. Basing on revealed differences in FA composition of wild and farmed fish, levels of 15-17-BFA (branched fatty acids), 18:2NMI (non-methylene interrupted), 20:2NMI, 20:4n-3, and 22:4n-3 fatty acids were recommended for verifying trade label information of fish products on shelves, as the biomarkers to differentiate wild and farmed charr.

Аннотация: The trophic position of fish is one of the most important factors controlling the accumulation of potentially toxic elements and compounds in fish tissues, primarily via the spectrum of fish nutrition. In this study, the content of potentially toxic transition metals (Cu, Zn, Mn, Pb, and Cd) and radiocesium (Cs-137) in the edible tissues (muscles and liver) of two representatives of the fish-eating ichthyofauna of the Yenisei River, northern pike (Esox lucius) and burbot (Lota lota), have been comparatively studied relatively to the size of the fish. A significant decrease in the content of radiocesium and zinc in the muscles of pike and zinc in the liver of pike with an increase in body size has been recorded in juvenile pikes with a body weight (W) of less than 0.35 kg. For larger sexually mature pikes, no significant size dependences of the accumulation of metals in tissues are found. A positive correlation is found between the content of Cs-137, Cu, Zn, and Mn in muscles and the size of burbot in the W range from 0.42 to 1.62 kg. The tissues of burbots and pikes of the same size significantly (p 0.05) differ in the concentration of metals in their tissues: concentrations of Zn and Mn are 1.6-2.2 times higher in the muscle of burbot; the concentration of Pb is 1.8 times higher in muscle of pike; Cu is twice as high in the liver of burbot; and Zn and Mn are 4.7 and 1.6 times higher in the liver of pike, respectively. These differences may be due to the different food spectra of pike and burbot. Concentrations of Cu, Zn, and Mn in the liver of pike are 3-7 times higher than in muscle; the concentration of Cu in the liver of burbot is 5 times higher than in muscle. Pb and Cd tend to be higher in liver than muscle for both fish species. Despite the revealed size dependences, the concentrations of potentially toxic metals and radiocesium in the muscles and liver of fish are below the permissible concentrations for food. These results can be used to assess environmental risks for the population consuming fish, as well as to plan for the long-term environmental monitoring of rivers using representatives of piscivorous fish.

Аннотация: A hypothesis was advanced and grounded that the total content of eicosapentaenoic (EPA, 20:5n-3) and docosahexaenoic (DHA, 22:6n-3) acids in fish muscle tissue is associated with the species-specific (taxon-specific) duration of embryo development. A meta-analysis of the original and published data was performed using fishes of the families Coregonidae and Salmonidae as an example. Fishes with longer embryo development times, which are observed at lower temperatures, were found to have significantly higher EPA + DHA contents in muscles as compared with the species that belong to the same families but have shorter embryo development times. This association was explained by the fact that an embryo forms more cells per unit tissue volume at lower temperatures, which requires a greater specific amount of cell membranes and, therefore, greater amounts of EPA and DHA to produce them.

Аннотация: In cold smoked species of genus Coregonus, identified by molecular genetic analysis, contents of fatty acids and heavy metals and arsenic were measured. The highest content of sum of long-chain polyunsaturated fatty acids of omega-3 family (LC-PUFA), namely eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids, 6.53 +/- 0.78 mg g(-1) wet weight, was characteristic of tugun Coregonus tugun. This is the first quantitative estimation (mg LC-PUFA per g of product) of the nutritive value of smoked fish. Thus, to obtain a daily personal doze of EPA + DHA of 1 g, recommended for prevention of cardiovascular diseases, one needs to consume 153 g of the smoked tugun. Metals contents did not exceed standards for fish meat except Pb in least cisco Coregonus sardinella. Accordingly, values of hazard quotients, which estimate benefit-risk ratio of fish intake, indicate that most of the smoked fish species are safe product for human nutrition, except least cisco regarding Pb content.

Аннотация: We compared the composition and content of fatty acids (FAs) in the liver, muscles, and subcutaneous fat of Yakut horses inhabiting extreme environment in the Cryolithozone. Essential linoleic and alpha-linolenic acids, supplied to horses with their food, were accumulated in different tissues. Linoleic acid was accumulated in the liver but alpha-linolenic acid was accumulated in muscle and subcutaneous fat. Such a distribution indicates different roles of these fatty acids in the metabolism of horses. Yakut horse meat is a valuable dietary product owing to its fatty acid composition and content.

Заглавие : Fatty acid analyses reveal high degrees of omnivory and dietary plasticity in pond-dwelling tadpoles

Аннотация: 1. Understanding the trophic relationships of consumers is central to ecology, but constructing meaningful food webs is often difficult because of a lack of detailed information on consumption versus assimilation and high degrees of omnivory.2. We used fatty acid analyses to examine the trophic relationships of three common larval anurans (Pseudacris crucifer, Lithobates catesbeianus and Lithobates clamitans) that are often classified as grazers or detritivores. Tadpoles and potential food sources were sampled in four ponds in southern Illinois and analysed for fatty acid composition. Single linkage cluster analysis was then used to compare fatty acid profiles among tadpole gut contents, tadpole muscle tissues and available food resources.3. Diets varied among species and within species among ponds, but organic sediments consistently contributed most to the fatty acid composition of the gut contents of all species. Fatty acid profiles also indicated that larval insects and phytoplankton were consumed by both L. catesbeianus and L. clamitans in one pond, while L. clamitans and P. crucifer consumed mainly periphyton along with sediments in another pond, and these diet differences appeared linked to physical differences among ponds, with periphyton and/or phytoplankton contributing more to tadpole diets in less shaded ponds.4. The fatty acid composition of muscle tissues of L. clamitans, the dominant tadpole in these systems, indicated that plant detritus and bacteria, which were the dominant components of organic sediments in the ponds, were common components of the assimilatory diet.5. Results demonstrate the utility of fatty acid analyses for assessing both consumption and assimilation. The tadpole assemblages we examined derive much of their energy from heterotrophic and allochthonous sources and exhibit high dietary plasticity. This information will allow for more accurate and comprehensive assessments of trophic interactions in freshwater habitats, as well as aid in amphibian conservation, management and captive propagation efforts.

Заглавие : Benefit-risk ratio of food fish intake as the source of essential fatty acids vs. heavy metals: A case study of Siberian grayling from the Yenisei River
Место публикации : Food Chemistry. - 2009. - Vol. 115, Is. 2. - С. 545-550. - ISSN 03088146 (ISSN) , DOI 10.1016/j.foodchem.2008.12.062
Ключевые слова (''Своб.индексиров.''): benefit-risk ratio--essential fatty acids--grayling--hazard quotient--heavy metals
Аннотация: A formula was derived for quantification of benefit-risk ratio (hazard quotient) for the intake of a product containing essential polyunsaturated fatty acids vs. heavy metals. The quotient was used in a three year case study of the contents of essential fatty acids and heavy metals in Siberian grayling, the main food fish from the middle section of the Yenisei River. As found, in general the fish intake was potentially very beneficial for human health, except on a few occasions, when the risk overweighed the benefit because of high contents of chromium in the fish muscle tissue. The data demonstrated the necessity for regular monitoring of the hazard quotients for food fish in wild conditions, based at least on monthly sampling frequency. В© 2008 Elsevier Ltd.
