For the first time, molecular sequences of the 18S ribosomal DNA were generated for representatives of the genera Sluys & Ball, 1989 and Sluys, 1989 of the suborder of the marine triclads, or Maricola, by analyzing the species (Hallez, 1906) and (Ijima & Kaburaki, 1916). On the basis of this molecular data the phylogenetic position of these two genera in the phylogenetic tree of the Maricola was determined and compared with their position in the phylogeny based on the analysis of anatomical features. New records for these two species are documented and their taxonomic status is determined on the basis of histological studies.

Background: Gastric cancer (GC) has a poor prognosis, considerable cellular heterogeneity, and ranks fifth among malignant tumours. Understanding the tumour microenvironment (TME) and intra-tumor heterogeneity (ITH) may lead to the development of novel GC treatments.

Methods: The single-cell RNA sequencing (scRNA-seq) dataset was obtained from the Gene Expression Omnibus (GEO) database, where diverse immune cells were isolated and re-annotated based on cell markers established in the original study to ascertain their individual characteristics.

Non-syndromic hearing loss (NSHL) is a genetically heterogeneous disorder accounting for almost 70% of the total congenital hearing loss. The implementation of rapid advanced sequencing methods has significantly contributed to the correct molecular diagnosis for several rare genetic disorders, including NHSL. Features of two probands with NHSL were clinically and genetically evaluated.
