Аннотация: The composition and content of fatty acids (FAs) in total lipids, triacylglycerols (TAG) and polar lipids (PL) in dominant groups of benthic invertebrates: gammarids (Gammaridae, Amphipoda), chironomid larvae (Chironomidae, Diptera), caddisfly larvae (Trichoptera) and mayfly larvae (Ephemeroptera) were studied in the Yenisei river. For the first time data on the FA composition of species belonging to Trichoptera (Insecta) are presented. The groups of aquatic insect larvae and gammarids weakly differed in total content of essential polyunsaturated fatty acids (PUFAs). Hence, the strong invasion of gammarids which occurred in the last decades in the Yenisei river should not result in a decrease in potential yield of essential PUFA in the ecosystem and corresponding decrease in food resource quality for fish in respect to PUFA content. Significant differences in biomarker FAs in TAG were found which correlated to specific food sources. Different levels of long-chain PUFA in PL of the invertebrates are discussed in relation to the genetic ability of particular taxa to form these FAs. (C) 2002 Elsevier Science Inc.

Bioluminescent microassay -- RNA aptamers -- Autoantibodies to myelin basic -- protein -- Multiple sclerosis
Аннотация: Bioluminescent solid-phase sandwich-type microassay was developed to detect multiple sclerosis (MS)-associated autoantibodies in human sera. The assay is based on two different 2'-F-Py RNA aptamers against the target autoantibodies as biospecific elements, and Ca2+-regulated photoprotein obelin as a reporter. The paper describes elaboration of the assay and its application to 91 serum samples from patients with clinically definite MS and 86 ones from individuals healthy in terms of MS. Based on the receiver-operator curve (ROC) analysis, the chosen threshold value as clinical decision limit offers sensitivity of 63.7% and specificity of 94.2%. The area under the ROC curve (AUC) value of 0.87 shows a good difference between the groups under investigation. The likelihood ratio of 10.97 proves the diagnostic value of the assay and its potential as one of the laboratory MS-tests. (C) 2019 Elsevier B.V. All rights reserved.
