[Liver transplantation program at the Burnasyan Federal Biophysical Center: experience in 500 procedures].

Objective: To analyze the features and outcomes of 500 liver transplantations in adults over a 12-year period.

Materials And Methods: The study included data on 500 liver transplantations between May 2010 and April 2023. We analyzed 483 adults who underwent transplantation and 438 candidates for this procedure.

Effect of Post-Implantation Heat Treatment Conditions on Photoluminescent Properties of Ion-Synthesized Gallium Oxide Nanocrystals.

A novel and promising way for creating nanomaterials based on gallium oxide is the ion synthesis of GaO nanocrystals in a SiO/Si dielectric matrix. The properties of nanocrystals are determined by the conditions of ion synthesis-the parameters of ion irradiation and post-implantation heat treatment. In this work, the light-emitting properties of GaO nanocrystals were studied depending on the temperature and annealing atmosphere.

Structure and Chemical Composition of Ion-Synthesized Gallium Oxide Nanocrystals in Dielectric Matrices.

The ion-beam synthesis of GaO nanocrystals in dielectric matrices on silicon is a novel and promising way for creating nanomaterials based on gallium oxide. This research studies the regularities of changes, depending on the synthesis regimes used, in the chemical composition of ion-implanted SiO/Si and AlO/Si samples. It has been shown that the formation of Ga-O chemical bonds occurs even in the absence of thermal annealing.

Experimental Limit on Nonlinear State-Dependent Terms in Quantum Theory.

Linear time evolution is one of the fundamental postulates of quantum theory. Past theoretical attempts to introduce nonlinearity into quantum evolution have violated causality. However, a recent theory has introduced nonlinear state-dependent terms in quantum field theory, preserving causality [D.

[Cut-off values of muscle mass indices at the level of ThXII and LIII vertebrae based on the computed tomography for the diagnosis of sarcopenia in the population of the Russia.].

There are original cut-off values of muscle mass indices measured by computed tomography for the diagnostic of sarcopenia in the different countries and regions of the world. In order to get corresponding data for Russia a retrospective analysis of computed tomography data of abdomen of 310 liver donors (151 women, 159 men) presented different country´s regions was performed. The analysis was carried out by two radiologists with more than 10 years of experience and included the determination of the areas of skeletal muscles at the level of the ThXII and LIII vertebrae, followed by the calculation of muscle mass indices with height normalization.
