The most significant achievements in the field of natural sciences are reached in joint collaboration, where important roles are taken by biology and chemistry. Therefore publication of a Journal, displaying results of current studies in the field of biology and chemistry, facilitates highlighting of theoretical and practical issues and distribution of scientific discoveries.One of the basic goals of the Journal is to promote the extensive exchange of information between the scientists from all over the world. We welcome publishing original papers and materials of Biological and Chemical Conferences, held in different countries (after the process of their subsequent selection).Creation of special International Journal of Biology and Chemistry is of great importance, because a great amount of scientists might publish their articles and it will help to widen the geography of future collaboration. We will be glad to publish also the papers of the scientists from the other continents.The Journal aims to publish the results of the experimental and theoretical studies in the field of biology, biotechnology, chemistry and chemical technology. Among the emphasized subjects are: modern issues of technologies for organic synthesis; scientific basis of the production of physiologically active preparations; modern issues of technologies for processing of raw materials, production of new materials and technologies; study on chemical and physical properties and structure of oil and coal; theoretical and practical issues in processing of hydrocarbons; modern achievements in the field of nanotechnology; results of studies in the fields of biology, biotechnology, genetics, nanotechnology, etc.We hope to receive papers from a number of Scientific Centers, which are involved in the application of the scientific principles of biology, biotechnology, chemistry and chemical technology on practice and carrying out research on the subject, whether it relates to the production of new materials, technology and ecological issues. Abstract: This work presents results on behavioral reactions and sensitivity of molluscs and fish to experimental modelling of accidental oil pollution during the first 72 hours. It is shown that mobile hydrobionts, such as fish attempt to escape the contaminated area during the first 24 hours after the oil spill. Benthic animals -molluscs are more susceptible to pollution, they almost instantly lose their mobility, become inert and try to escape their shells further on, which serves as an evidence of death throes. Light crude with high content of paraffin was used for the present experiment.
Background Hedysarum L. is one of the large families of the Fabaceae, consisting of 200 species. Species in the genus Hedysarum are valuable forage and medicinal resources. In this paper we studied Hedysarum theinum Krasnob. and Hedysarum neglectum Ledeb. growing in the Western Altai of Eastern Kazakhstan. H.theinum is a perennial, herbaceous, valuable medicinal plant, a rare high-altitude species, an Altai-Dzungarian endemic and globally endangered species. H. neglectum is a perennial plant of high medicinal and fodder value, growing mainly in the sub-alpine zone. A complex phytochemical study of Hedysarum using modern methods, expanding the data on herbal medicines is actual. At the current time, taxonomic and phylogenetic questions of the genus Hedysarum are the subject of close attention, as the systematic knowledge of the genus Hedysarum L. Fabaceae: Hedysareae is still incomplete. Therefore, questions are being actively addressed by correlating data obtained by molecular genetic analyses. In the study, route-recognition methods were used in a field search of two species of Hedysarum for comparative morphological study in 2020–2021. Results The morphological measurements showed a difference in the external structure of the two species. Structural changes in the anatomical structure of the leaf, stem and root were analyzed as the plants adapted to different conditions in the Western Altai. The changes were expressed in the transition from the typical dorsiventral leaf structure of H.theinum to the isolateral-palisade structure of the mesophyll of H.neglectum. The phytochemical analysis revealed the highest amount of ethyl α-d glucopyranoside at 45.23% in the subterranean part of H. theinum, which was only 0.8% in H. neglectum. The root part of H. theinum contained the highest vitamin E content of 11.36%, while the above-ground part of H. neglectum showed an insignificant amount of tocopherol at 0.37%. Also the above-ground and underground parts of the two species contain squalene, which has an antioxidant effect and strengthens the immune system. Nowadays, an urgent task in pharmacognosy is the use of all kinds of DNA analysis methods for the identification of plant raw materials. In this regard, the possibility of using molecular genetic methods of research in the analysis of representatives of the genus Hedysarum L., for the identification of medicinal plant raw materials was studied. Conclusion Phylogenetic analysis using molecular genetic markers revealed that H. neglectum and H. theinum belong to the Hedysarum section. The data obtained can be used for the species identification of H.theinum and H.neglectum, which has so far been difficult due to the lack of some systematic morphological characters. The results obtained may be useful for the taxonomic studies of this section.
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.
