The effect of cell therapy on the intensity of lipid peroxidation processes in the liver, kidneys and lungs of rats of different ages under conditions of experimental cranio-skeletal trauma.

Objective: Aim: To determine the effect of cell therapy on the intensity of lipid peroxidation processes in the liver, kidneys and lungs of rats of different ages under conditions of experimental cranio-skeletal trauma (CST).

Patients And Methods: Materials and Methods: In the experiments, 129 white male Wistar line rats of different age groups were used: immature rats aged 100-120 days and weighing 90-110 g; mature rats aged 6-8 months and weighing 180-200 g; and old rats aged 19-23 months and weighing 300-320 g. In each age group, CST was modeled under thiopental sodium anesthesia.

Al-Pt intermetallic compounds: HAXPES study.

Intermetallic compounds in the Al-Pt system were systematically studied hard X-ray photoelectron spectroscopy, focusing on the positions of Pt 4f and Al 2s core levels and valence band features. On one hand, with increasing Al content, the Pt 4f core levels shift towards higher binding energies (BE), revealing the influence of the atomic interactions (chemical bonding) on the electronic state of Pt. On the other hand, the charge transfer from Al to Pt increases with increasing Al content in Al-Pt compounds.

Al-Pt compounds catalyzing the oxygen evolution reaction.

Al-Pt compounds have been systematically studied as electrocatalysts for the oxygen evolution reaction (OER). Considering the harsh oxidative conditions of the OER, all Al-Pt compounds undergo modifications during electrochemical experiments. However, the degree of changes strongly depends on the composition and crystal structure of a compound.

INITIATING FACTORS OF COMPLICATIONS DEVELOPMENT DURING PROSTHETICS OF TEETH WITH FIXED PROSTHESES.

Objective: The aim: Determination of the factors complications occurrence in prosthetics with metal-ceramic prostheses.

Patients And Methods: Materials andmethods: Clinical, cytological, cytochemical methods and methods of statistical processing of the received data are applied.

Results: Results: A number of factors with different degrees of significance have been identified, which in the dynamics of clinical observations of the percentage of absorbed dispersion are decisive in the development of changes in the gums.

Influence of two-hour tourniquets ischemia of limb and acute blood loss on systemic disorders of the body in the reperfusion period (experimental study).

Objective: The aim: to find out the effect of a two-hour tourniquets ischemia of the limb and acute blood loss on systemic disorders of the body in the postperfusion period.

Patients And Methods: Materials and methods: The experiments were performed on 96 nonlinear male rats weighing 200-220 g. All experiments were performed under sodium thiopental anesthesia.
