This paper presents the first report of male specimen of Paralongidorus rex Andrássy, 1986. It was found in the population collected from the rhizosphere of Acer platanoides in Lviv, Ukraine. Morphology of male, especially structure of spicules and arrangement of supplements, is described in details and compared with most closely related species. It can be distinguished from all other similar species by longer spicules. Morphometric data on females and male of this population are provided. Morphology of female genital tract is described in details. Uterine eggs are detected in genital tract of females for the first time and their morphometrics are provided. During current research, clearly expressed seasonal reproduction of this parthenogenetic species on the territory of Western Ukraine was revealed. Uterine eggs were observed only in genital tracts of females from the soil samples collected in the first decade of May but no female specimens with eggs were detected in numerous P. rex populations collected during summer period (June-September).

Endometrial carcinoma (EC) is one of the most common malignancies of the female genital tract, although the mechanisms of EC initiation and development remain incompletely understood. In this study, we demonstrated that the noncoding RNA SNHG5 can inhibit the proliferation, migration, and invasion of EC cells by suppressing the expression of its putative target miR-25-3p. Overexpression of miR-25-3p significantly promoted the proliferation, migration, and invasion of EC cells. In addition, we showed that miR-25-3p represses the expression of BTG2 by directly binding to the 3′-UTR of BTG2 mRNA. Furthermore, increased miR-25-3p expression and decreased SNHG5 and BTG2 expression were observed in EC tissues, and the expression of SNHG5 was negatively correlated to that of miR-25-3p but positively correlated to that of BTG2. In summary, for the first time, we report that the SNHG5/miR-25-3p/BTG2 axis plays an important role in EC progression and is of great potential clinical significance for EC diagnosis and therapy.

Euastrum lacustre is reported for Russia for the first time. This alcaliphilic species was found in the periphyton and plankton of three lakes in the Kursk Region (European Russia). A description of morphology, including the relief of cell wall, and habitats where this taxon is found are represented. LM and SEM microphotographs are provided. Morphological differences of E. lacustre from similar species are discussed. New species for region, namely Closterium aciculare, Cosmarium formosulum, C. granatum, C. pseudoinsigne, C. reniforme and Staurastrum pingue, are found in the samples together with E. lacustre.
