Публікація Acoustomagnetic detection of magnetic nanoparticles in a model(The International Journal of Artificial Organs, 2019) Bondarenko, I. S.; Аврунін, О. Г.; Gryshkov, O.; Glasmacher, B.; Bondarenko, S. I.; Krevsun, A. V.; Rakhimova, M. V.Magnetic nanoparticles (MNPs) are used in medicine for targeted drug delivyry to the area of the cancer. The installation consists of the ultrasound generator, the permanent magnet, the glass containerwith the colloidal mixture, the multi-turn coil about of the glass tube and the voltmeter. The experimental result corrilates with the calculated ones. It is suggested that AMM can used to detect MNPs in the real biological substance.Публікація Advances in cryopreservation of alginate-encapsulated stem cells and analysis of cryopreservation outcome(Інститут проблем кріобіології та кріомедицини НАН України, 2018) Gryshkov, O.; Mutsenko, V.; Tymkovych, M.; Tarusin, D.; Sirotinskaya, V.; Braslavsky, I.; Аврунін, О.

This work suggests that using controlled cryopreservation steps and EG as a non-toxic CPA, efficient cryopreservation of TECs in cryobags becomes feasible.Публікація Image processing for semi-automated microscopic analysis of ice recrystallization process during isothermal annealing(IJBM, 2018) Prykhodko, M. V.; Тимкович, М. Ю.; Аврунін, О. Г.; Mutsenko, V. V.; Gryshkov, O.; Glasmacher, B.Investigation of the process of crystallization is a complex and important task, especially in cryopreservation of biological material for medical purposes. In the current work, the process of processing and analyzing a series of microscopic images during freezing and thawing is considered. Based on available literature as well as our image processing approach, it is now possible to analyze ice recrystallization process during thawing and isothermal annealing. Moreover, using our approach tracking of certain ice crystals can be performed. This knowledge can now be applied for precise determination of the efficiency of inhibition of ice recrystallization of novel and low-toxic cryoprotective agents.Публікація Image-series analysis for recrystallization process evaluation(ХНУРЕ, 2018) Аврунін, О.
