Abstract

The paper proposes a technology for obtaining samples of the composite material "PLA 90kDA - heparin" with different concentrations of heparin (from 1 to 5 wt %). The structure of the obtained composite material samples using SEM is considered. The dependences of the tensile strength and deformation on the concentration of heparin in the composite material are revealed. The developed technology can be used to obtain a functional coating on medical implants, such as stents, to eliminate possible postoperative complications. [ABSTRACT FROM AUTHOR]

19. An overview of waste recycling and artificial soil production.

Author

Sevostyanov, M. A., Sevostyanova, E. P., Sergienko, K. V., Kaplan, M. A., Baikin, A. S., Kosolapov, V. M., Glinushkin, A. P., and Morozova, Ya. A.

Abstract

The paper considers methods for obtaining organic fertilizers and artificial soils, as well as waste used in these methods. The use of such technologies and the products produced due to them in peacetime can be used to restore land after chemical contamination, such as bottling of oil products, chemicals, as well as to increase productivity due to the complex replenishment of useful substances washed out and drawn out during plant growth. In wartime, the produced artificial soil is important from the point of view of the country's food security, allowing plants to be grown in lands not originally intended for agricultural purposes, as well as in greenhouses and isolated premises.

Abstract

This article discusses the main causes of complications in the process of osseointegration of dental implants, which, among other things, are associated with the peculiarities of the Arctic zone. The main biomechanical and biocompatible factors of dental implant design, applied materials and surface conditions, which together affect the quality and strength of osseointegration, the bone-implant interface and their relationship with the long-term survival success of dental implants and restorations, are described.

Abstract

Titanium-based alloy with low-toxic metals such as niobium, tantalum and zirconium (TiNbTaZr) was manufactured. The primary weight percentages of elements used for fusion were: titanium, 65%; niobium, 20%, tantalum, 10%; and zirconium, 5%. The TiNbTaZr alloy had a yield strength of about 550 MPa, a tensile strength of about 700 MPa, and a Young’s modulus of about 50 GPa, that is, it was comparable with Nitinol. A primary study of the biocompatibility of the TiNbTaZr alloy using the SH-SY5Y cells showed that the alloy did not have significant short-term toxicicity towards the cells incubated on the alloy surface. The number of non-viable cells was 2.5 times lower on the TiNbTaZr alloy than on Nitinol. The biocompatibility of TiNbTaZr was more pronounced than that of the Nitinol reference sample.
