Test kit for detection of IgG-antibodies to individual antigens of Toxoplasma gondii by immune blotting («Western blot» format) has been developed. Laboratory testing with first international WHO standard «Anti-toxoplasma serum (IgG), human, Lyophilized, 20 IU / ampoule» (NIBSC, Great Britain) demonstrated the analytical sensitivity of the new kit equal to 10 IU / ml. Study of the diagnostic efficiency of the new kit showed its high sensitivity, equal to 98.51 - 100%, and high specificity, equal to 99.5 - 100%. New test kit is intended for confirmatory testing in laboratory diagnostics of toxoplasmosis.
Both bee products themselves and their combinations are widely represented in the domestic pharmaceutical market, however, modern experimental studies of the biological activity of these compounds are few, and in many of the existing publications the authors describe an extremely wide and controversial range of therapeutic effects.The aimof the study is to analyze the experimental works on the study of biological activity of bee products.Materials and methods.The study was conducted using search and information (eLibrary, PubMed, CyberLeninka, ResearchGate) and library databases (Russian State Library, Central Scientific Agricultural Library). In the designated databases, publications were searched by such terms as “biological activity”, “royal jelly”, etc. The depth of the search was not limited.Results and discussion.The analysis of the published works shows that such substances as bee venom and royal jelly have experimentally confirmed their biological activity. In both cases, the active substances have been described and a review of their detected biological activity has been carried out.Conclusion. The authors suggest that when developing the method of laboratory synthesis of decene acids, it can be possible to carry out their large-scale preclinical research, which may become the basis for the creation of a drug with a selective effect.
The problem of import substitution in the Russian medical device market for in vitro diagnostics (MDivd) has not been solved, despite a number of measures taken by the government of the Russian Federation since 2011. The reasons hampering this process are the lack of modern analytical equipment of domestic production and deficiencies of the current regulatory system for MDivd circulation in the market. It is proposed the transition from licensing system of MDivd registration to notification system as a radical measure to solve the problem of import substitution.
The developing and the testing results of an immunochromatographic test for the D-dimer qualitative determination were presents in the article. The test was approved blood plasma samples in comparison with a quantitative enzyme-linked immunosorbent assay (ELISA). The results of assay with developed test were the same with ELISA results for 87,1% and 100% for samples with increased (more than 400 ng/ml FEU) and normal concentration of D-dimer, respectively. The immunochromatographic test for determination of D-dimer can be included in the diagnostic strategy as a cut test after the assessment of venous thromboembolism risk.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
