the current research is devoted to the study of the modification of the titanium implants by the micro-arc oxidation with bioactive calcium phosphate coatings containing Ag or Sr and Si *** coatings’microstructure,phase composition,morphology,physicochemical and biological properties were examined by scanning electron microscopy(SEM),transmission electron microscopy(tEM),energy-dispersive X-ray spectroscopy(EDX)and X-ray diffraction(XRD).Ag-containing and Sr-Si-incorporated coatings were formed in alkaline and acid electrolytes,*** formation of the coatings occurred at different ranges of the applied voltages,which led to the significant difference in the coatings *** trace elements Ag,Sr and Si participated intensively in the plasma-chemical reactions of the micro-arc coatings ***-containing coatings demonstrated strong antibacterial effect against Staphylococcus aureus AТСС*** in vitro test with 3t3-L1 fibroblasts showed no cytotoxicity appearance on Sr-Si-incorporated coatings.

the Species of the Genus Gagea Salisb. Is Distribution in the Flora of the Urgut Region (Uzbekistan)

引用

American Journal of Plant Sciences 2022年第9期13卷 1183-1195页

作者： Gulsauir t. Kurbaniyazova Igor G. Levichev Ulugbek Kh. Kadirov Institute of Botany of the Academy of Sciences of the Republic of Uzbekistan Tashkent Uzbekistan Institute of Botany after Named V. L. komarova Russia Academy Sciences Sankt Peterburg Russia

In this article, 1650 herbarium specimens of representatives of the genus Gagea Salisb. were used as research material from the collections of the National Herbarium of Uzbekistan (tASH). It presents a geographical coordinate system, habitats, phenology, and economic values. the distribution of species in Uzbekistan was indicated by the phytogeographic regions of the country. the herbarium material of Gagea Salisb. has been studied in tASH, SAMSU and MSU. the tASH Herbarium presents samples from 1914 to 2019. the review was written using information published between 1988 and 2019 from a number of reliable sources, including Science Direct, Springer, PubMed, EMBASE and Wikipedia.
