AbstractThe change in the state of the mitochondrial pore of nonspecific conductivity plays a key role in the processes of triggering and regulating apoptosis. Therefore, the study of mechanisms of opening and regulating the state of these pores can have a great importance to find the ways of correcting many mitochondrial dysfunctions, including those which are associated with age-related changes. In our work, we have done a comparative analysis for swelling of brain mitochondria of adult (9 months) and mature rats (12-15 months).

Purpose of the study to carry out a comparative analysis of the state of the zonular fibers before and after surgery on UBM between femtolaser assisted and classical ultrasound cataract removal. Material and methods. 19 patients (38 eyes) with age-related cataracts. 22 eyes were with pseudo-exfoliative syndrome. All patients were examined with grade 1 lens subluxation. The first group of 19 eyes underwent cataract femto-phacoemulsification. The second group included 19 eyes without using a femtolaser. The state of the fibers was determined on the UBM on the fifth day after the operation at the end of antibiotic therapy. Results. The data showed the presence of a statistically significant difference between the group with femto-assistance and the group without it. In the first group, UBM analysis showed that the state of the zonular fibers remained in the same state in 16 of 19 eyes. In the second group, 11 of 19 eyes required ring implantation with suturing to the sclera and 3 required IOL implantation with seamless fixation to the sclera and vitrectomy. Conclusions. The appropriate path to surgery depends on the most accurate objective assessment of the condition of the lens ligaments, since the position of the IOL is one of the main factors for a good result expected by the patient after surgery. Reducing the «trauma» of the eye with lens surgery has been a key success factor and femtolaser guidance provides valuable assistance in obtaining it. Key words: lens subluxation, femtosecond laser, UBM.

A comparative analysis of results of examination of patients with chronic brain vascular insufficiency and findings on reference group was carried out. The significance of age-related and vascular risk factors in development of changes in external and internal liquoroconductive spaces is stated. It is noted that insignificant and moderate dilatation of subarachnoid spaces and ventricular systems mainly indicate natural involutional processes. Heterogeneity of anterior and posterior regions involvement of subarachnoid spaces in brain aging are revealed. Influence of silent ischemic insults on the state of ventricular system is mentioned.

This article presents a comparative analysis of the parameters of HRV students who are indigenous and non-indigenous residents of Yugra. Analysis was carried out carried out by multiple comparisons of three age subgroups and by multivariate analysis with the calculation of inter-cluster distances. The differences in the dynamics of age-related changes of Yugra schoolchildren reveals distinctive trend parameters of heart rate variability between indigenous and non-indigenous representatives of North. In particular, it revealed a higher adaptive capacity in Aboriginal representatives in comparison with the migrant population. The maximum divergence of parameters of the body boys observed in the older age group.
