Effect of Cold Drawing and Annealing in Thermomechanical Treatment Route on the Microstructure and Functional Properties of Superelastic Ti-Zr-Nb Alloy.

In this study, a superelastic Ti-18Zr-15Nb (at. %) alloy was subjected to thermomechanical treatment, including cold rotary forging, intermediate annealing, cold drawing, post-deformation annealing, and additional low-temperature aging. As a result of intermediate annealing, two structures of -phase were obtained: a fine-grained structure (d ≈ 3 µm) and a coarse-grained structure (d ≈ 11 µm).

Avidity of IgG to SARS-CoV-2 RBD as a Prognostic Factor for the Severity of COVID-19 Reinfection.

The avidity index (AI) of IgG to the RBD of SARS-CoV-2 was determined for 71 patients with a mild (outpatient) course of COVID-19, including 39 primarily and 36 secondarily reinfected, and 92 patients with a severe (hospital) course of COVID-19, including 82 primarily and 10 secondarily infected. The AI was shown to correlate with the severity of repeated disease. In the group of outpatients with a mild course, the reinfected patients had significantly higher median AIs than those with primary infections (82.

New prognostic criterion for the outcome of pregnancy in patients with threatening preterm birth.

To identify new criteria for predicting the outcome of pregnancy in women with threatened preterm labor based on the establishment of the characteristics of differentiation and functional activity of memory T-cells in the population of CD8 + T-lymphocytes. The study involved 56 women with threatened preterm labor at 22-34 weeks of pregnancy. Depending on the outcome of pregnancy, patients were divided into 3 groups: Group I included 22 women by premature labor; group II - 34 women whose pregnancy ended by deliver at term.

Character of β-lymphocytes differentiation in women with hypertensive disorders during pregnancy.

The aim of the work was to identify the features of B-lymphocyte differentiation in women with hypertensive disorders of various origins, to establish their relationship with indicators of the elastic properties of the vascular wall, and to develop additional diagnostic criteria for the severity of preeclampsia. We examined 193 women at 24-40 weeks of gestation. Of these, 39 women with chronic arterial hypertension, 35 women with preeclampsia that developed against the background of chronic arterial hypertension, 55 with preeclampsia.
