[Gerontological aspects of improving the quality of medical and social assistance to older displaced persons in the context of the COVID-19 pandemic in Ukraine.].

This work aimed to study the organization of medical-social services for the elderly internally displaced persons at the level of primary medico-sanitary aid (PMSA) in Ukraine, assessment of the main tasks and specifics of organization and provision of palliative and hospice care (PHC) under COVID-19 conditions. As a result of the sociological investigation, using the questionnaire methods and experts' evaluations, we have analyzed the socio-psychological characteristics of the elderly internally displaced persons, the specifics of their social adaptation, financing and medico-social servicing at the level PMSA, including structural modernization and optimization of organizational provision. The introduction of an affordable and economically viable system allows for the interaction of specialists from health care and social protection institutions, and optimizes compliance with the standards and principles of medical care.

Chronomics of tree rings for chronoastrobiology and beyond.

Gliding spectral windows illustrate the changes as a function of time in the relative prominence of signals in a given frequency range, viewed in 3D or as surface charts. As an example, the method is applied to a 2,189-year series of averages of ring measurements on 11 sequoia trees published by Douglass. Analyses of the original data and after filtering reveal, among others, components with periods of about 10.

[Radioprotective action of a gas hypoxic mixture GHM-10 in multiple irradiations of rat and human skin].

Gas hypoxic mixture (GHM-10) decreased significantly the occurrence and duration of radioepidermitis after local therapeutic fractionated irradiation of Wistar rat skin with a cumulative dose of 66 Gy. In patients subjected to radiation therapy and protected with GHM-10 erythema and epidermitis developed at a much higher cumulative dose than in the controls. With erythema dose modifying coefficient was 1.

[Inhibition of fibrin assembly by fragment D and its dimer derived from fibrinogen and stabilized fibrin. Evidence for the two-step type of inhibition].

The influence of purified fragments D and DD on fibrin monomer polymerization has been studied. When applied separately, DD is less strong an inhibitor than D. An addition of small amounts of DD to the reaction mixtures containing D does not change the inhibitory effect, when the concentration of the latter fragment is low.

[Determination of fibrinogen concentration in blood plasma by the sulfite precipitation method].

Two methods using thrombine and sulfite were compared for estimation of fibrinogen concentration in blood plasma. Both methods produced the same results in estimation of fibrinogen in donor blood plasma. If blood plasma contained high amount of products of fibrinogen and/or fibrin degradation, the efficiency of thrombin method was decreased; on the other hand, final concentration of sulfite did not precipitate fragment D of fibrinogen from human blood plasma.
