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

Аннотация: Polyhydroxyalkanoate (PHA) sutures were implanted to test animals intramuscularly, and tissue reaction was investigated and compared with the reaction to silk and catgut. Tested monofilament sutures made of PHAs of two types-polyhydroxybutyrate (PHB) and a copolymer of hydroxybutyrate and hydroxyvalerate (PHV)-featured the strength necessary for the healing of muscle-fascial wounds. The reaction of tissues to polymeric implants was similar to their reaction to silk and was less pronounced than the reaction to catgut; it was expressed in a transient post-traumatic inflammation (up to four weeks) and the formation of a fibrous capsule less than 200 mum thick, which became as thin as 40-60 mum after 16 weeks, in the course of reverse development. Macrophages and foreign-body giant cells with a high activity of acid phosphatase were actively involved in this process. PHB and PHB/PHV sutures implanted intramuscularly for an extended period (up to one year) did not cause any acute vascular reaction at the site of implantation or any adverse events, such as suppurative inflammation, necrosis, calcification of the fibrous capsule or malignant tumor formation. No statistically significant differences were revealed in the tissue response to polymer sutures of the two types. Capsules around silk and catgut sutures did not become significantly thinner.

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: 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.

Заглавие : Semisynthetic photoprotein reporters for tracking fast Ca2+ transients
Место публикации : Photochem. Photobiol. Sci. - 2015. - Vol. 14, Is. 12. - С. 2213-2224. - ISSN 1474905X (ISSN) , DOI 10.1039/c5pp00328h
Аннотация: Changes in the intracellular concentration of free ionized calcium ([Ca2+]i) control a host of cellular processes as varied as vision, muscle contraction, neuronal signal transmission, proliferation, apoptosis etc. The disturbance in Ca2+-signaling causes many severe diseases. To understand the mechanisms underlying the control by calcium and how disorder of this regulation relates to pathological conditions, it is necessary to measure [Ca2+]i. The Ca2+-regulated photoproteins which are responsible for bioluminescence of marine coelenterates have been successfully used for this purpose over the years. Here we report the results on comparative characterization of bioluminescence properties of aequorin from Aequorea Victoria, obelin from Obelia longissima, and clytin from Clytia gregaria charged by native coelenterazine and coelenterazine analogues f, i, and hcp. The comparison of specific bioluminescence activity, stability, emission spectra, stopped-flow kinetics, sensitivity to calcium, and effect of physiological concentrations of Mg2+ establishes obelin-hcp as an excellent semisynthetic photoprotein to keep track of fast intracellular Ca2+ transients. The rate of rise of its light signal on a sudden change of [Ca2+] is almost 3- and 11-fold higher than those of obelin and aequorin with native coelenterazine, respectively, and 20 times higher than that of the corresponding aequorin-hcp. In addition, obelin-hcp preserves a high specific bioluminescence activity and displays higher Ca2+-sensitivity as compared to obelin charged by native coelenterazine and sensitivity to Ca2+ comparable with those of aequorin-f and aequorin-hcp. © The Royal Society of Chemistry and Owner Societies 2015.

Аннотация: Seasonal variations of fatty acid contents in muscle tissue of one of the main food fish species in Siberian rivers, grayling, Thymallus arcticus, were studied over 3 years. Under a comparatively low range of water temperature variations, spawning appeared to be the main cause of seasonal changes in contents of quantitatively prominent and essential fatty acids in fish filets. In general, fish accumulated essential polyunsaturated fatty acids (PUFA), such as eicosapentaenoic (EPA) and docosahexaenoic (DHA), in their muscle tissue before reproductive seasons and then the PUFA seemed to be transferred into gonads during their formation. Hard roe of Siberian grayling had 3-4 times higher PUFA contents, than had that of the muscle tissue. The fish species, T. arcticus, was found to be a valuable source of the essential PUFA, including EPA and DHA, for human diet. В© 2007 Elsevier Ltd. All rights reserved.

Аннотация: The paper presents the results of biomedical investigations of sutures made of polyhydroxyalkanoates (PHAs) of two types (poly-3-hydroxybutyrate (PHB) and poly-3-hydroxybutyrate-co-poly-3-hydroxyvalerate (PHB/PHV)), synthesized by the bacteria Ralstonia eutropha B 5786 in the experiment on test animals in vivo, in comparison with silk and catgut sutures. PHB and PHB/PHV (PHBV) implants produced no adverse effect on physiological, biochemical and functional parameters of the animals during the post-surgery period. The tested PHA sutures featured the necessary strength throughout the healing period of the muscle-fascial cuts. The reaction of tissues to the implantation of PHB and PHB/PHV fibers fitted into the usual scheme characteristic of the wound process and of the reaction to a foreign-body invasion. This reaction and the reaction of tissues to silk had the similar nature and period of inflammation, but it was much less pronounced than the reaction to catgut. The tissue response to the implantation of PHAs consisted in a short-duration (up to 2 weeks) post-traumatic inflammation and the formation of a fibrous capsule less than 200 mum thick during weeks 4-8, which in 4-6 months was reduced to 40-60 mum in the course of reverse development. There were no adverse changes, such as suppurative inflammation, necrosis, calcification, and malignization of the cicatrice, at the site of implantation of PHA filaments, unlike in the cases with silk and catgut. In the case of PHA implantation there was a typical prolonged (throughout the post-surgery monitoring period) pronounced macrophagal stage with a large number of macrophages present. The macrophages were of the phagocytic type and multinucleate giant foreign cells, with a high activity of acid phosphomonoesterase that correlated with the activity of the enzyme in blood. Throughout the period of monitoring no differences in the tissue response to the implantation of the polymer filaments of two PHA types were recorded. (C) 2003 Elsevier Science B.V.

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: 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 n-3 fatty acids (LC-PUFA), including eicosapentaenoic (EPA), and docosahexaenoic (DHA) are an essential part of human diets, but their main source, the wild fish catch, is limited. Terrestrial production animals, such as cattle, pigs, and chicken, can synthesize these compounds from the plant-derived precursor -linolenic acid, and the synthesis occurs mainly in liver. We estimated the putative contribution of liver products to the LC-PUFA supply in human nutrition, as an alternative to fish. We measured EPA and DHA contents in raw and cooked livers of the animals. Calculations of global production of EPA and DHA in the livers of these animals were done. Mean contents of LC-PUFA in raw livers of chicken, pigs, and cattle were comparable with those in some fish. Culinary treatments of the liver did not result in a decrease of EPA and DHA contents. Global production of EPA and DHA in animals' livers was estimated as approximate to 410(6)kg/year, while the global EPA+DHA supply through the wild fish catch is known to be 18010(6)kg/year. Thus, liver of production animals is an additional source of LC-PUFA for human nutrition, rather than an alternative to fish. Practical applications: Consumption of food with a high PUFA content and a low n-6/n-3 ratio is recommended for humans to prevent cardiovascular disease and psychiatric disorders. We found that cooked pork and beef liver is a valuable source of n-3 LC-PUFA in human nutrition. In contrast, cooked chicken liver had too high of a n-6/n-3 ratio and, thereby, had a lower nutritive value concerning n-3 LC-PUFA. An estimate has been made of the putative contribution of liver products of terrestrial animals to the LC-PUFA supply as alternative to fish in human nutrition.

Заглавие : Fatty acid content and composition of the yakutian horses and their main food source: living in extreme winter conditions
Место публикации : Biomolecules: MDPI AG, 2020. - Vol. 10, Is. 2. - Ст.315. - ISSN 2218273X (ISSN), DOI 10.3390/biom10020315
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. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.

Заглавие : Fatty acid content and composition in tissues of Baikal grayling (Thymallus baicalensis), with a special focus on DHA synthesis
Место публикации : Aquac. Int.: Springer Science and Business Media Deutschland GmbH, 2021. - Article in press. - ISSN 09676120 (ISSN), DOI 10.1007/s10499-021-00755-w
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. © 2021, The Author(s), under exclusive licence to Springer Nature Switzerland AG.

Аннотация: Abstract: 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. © 2020, Pleiades Publishing, Ltd.

Ключевые слова (''Своб.индексиров.''): eicosapentaenoic acid--docosahexaenoic acid--anadromous fish--freshwater--fish--planktivory--benthivory
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.
