The increasing popularity and recognition of citizen science approaches to monitor soil health have promoted the idea to assess soil microbial decomposition based on a standard litter sample - tea bags. Although tea bag initiatives are expanding across the world, the global datasets remain biased in regard to investigating regions and biomes. This study aimed to expand the tea bag initiative to European Russia, which remains a "white spot" on the tea bag index map.

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.

Perinatal lesions of the Central nervous system (CNS) in newborns occupy a leading place in the structure of perinatal morbidity and subsequent disability of children. To identify the features of the content of sRAGE in pregnant women with threatening preterm labor (UPR) in the period of 22-27 weeks, who subsequently gave birth to children with perinatal CNS lesion. Serum of venous blood of pregnant women with UPR at the term of 22-27 weeks was determined by ELISA once the content of sRAGE.

In patients with different clinical variants of uterine leiomyoma (large or small size, presence or absence of intensive proliferation of tumor cells) the comparative analysis of endometrial CD56+ natural killers (NK) activation was carried out. The relative content of CD56+ cells, expressing of CD158a and CD158i molecules from KIR (killer immunoglobuline-like receptors) family, interferon γ (IFNγ) and transforming growth factor β1 (TGFβ1), was estimated by flow cytometry method. It was found that in the endometrium of all patients with uterine leiomyoma independently of tumor size the content of CD56+ cells and the amount of NK, expressing both activating (CD158i) and inhibitory (CD158a) receptors, were increased.

The content of some cytokines in the peritoneal fluid and the level of their in vitro production by peritoneal macrophages and lymphocytes were evaluated in women with external endometriosis. The ratio of peritoneal lymphocytes and macrophages in the peritoneal fluid was changed in endometriosis because of increased percentage of lymphoid cells and decreased content of macrophages, in the presence of high absolute counts of both types of cells. The cytokine status of women with endometriosis was characterized by higher levels of IL-1beta, TNF-alpha, and epidermal growth factors both in the peritoneal fluid and supernatants of 24-h cultures of peritoneal macrophages; the content of IFN-alpha remained unchanged.
