1. In-domatic number and some operations in digraphsGermán Benítez-Bobadilla, Laura Pastrana-Ramírez, 2026, izvirni znanstveni članek Opis: Let D be a digraph, a subset S of V(D) is called in-dominating set in D if for each vertex x ∈ V(D) \ S there is a vertex w ∈ S such that (x, w) ∈ A(D). An in-domatic partition of D is a partition of V(D) where all parts are in-dominating sets in D. The maximum number of parts of an in-domatic partition of D is the in-domatic number of D and it is denoted by d⁻(D). In this work, the in-domatic number for some families of digraphs such as complete digraphs, transitive digraphs, directed cycles and the cartesian product of two cycles, is calculated. Also, in-domatically critical digraphs are characterized. Additionally, the in-domatic partitions of the line digraph and some other operations which reflect the adjacency and incidence relations in digraphs are explored.

2. The impact of Aureobasidium melanogenum cells and extracellular vesicles on human cell linesAnja Černoša, Cene Gostinčar, Marija Holcar, Rok Kostanjšek, Metka Lenassi, Nina Gunde-Cimerman, 2025, izvirni znanstveni članek Opis: Aureobasidium melanogenum is a black yeast-like fungus that occurs frequently both in nature and in domestic environments. It is becoming increasingly important as an opportunistic pathogen. Nevertheless, its effect on human cells has not yet been studied. In this study, we investigated the effect of A. melanogenum cells and extracellular vesicles (EVs) on human cell lines A549 (human lung cells), HDFa (human dermal fibroblasts), and SH-SY5Y (human neuroblastoma cells). Scanning electron microscopy (SEM) showed no direct interaction between A. melanogenum cells and human cell lines, but there were some changes in HDFa cells. As a possible cause for this change, we tested the cytotoxic effect of EVs from A. melanogenum on the same cell lines. We isolated EVs from the fungus and prepared three different pools: a non-melanin pool (containing mainly EVs), a melanin pool (containing mainly melanin nanoparticles), and a total pool (containing both EVs and melanin nanoparticles). All three pools were characterized and then added to human cell lines to test their cytotoxicity. Unlike in some other fungal opportunistic pathogens, no effects of fungal EVs on human cell viability were observed. Therefore, the opportunistic potential of A. melanogenum remains only partially understood.
