The complete nucleotide sequence of a Polish isolate of Beet soil-borne virus was determined for the first time. The genome organization was identical with those previously established for isolates from Germany and China. A comparison of the Polish isolate with others deposited in GenBank revealed high level of nucleotide identity, about 98-100%, throughout the genome analyzed. The ratio between non-synonymous and synonymous substitutions was rather low suggesting a negative selective pressure. The non-synonymous mutations were particulary frequent in triple gene block.

Background: Tauopathies are a group of neurodegenerative disorders which are characterized by the accumulation of abnormal tau protein in the brain. However, the mechanistic understanding of pathogenic tau formation and spread within the brain remains elusive. Astrocytes are major immune reactive cells in the brain and have been implicated in exacerbating tau pathology by releasing extracellular vesicles (AEVs) containing pro-inflammatory cytokines and chemokines upon activation.

We report the synthesis, isolation, and comprehensive characterization of N-heterocyclic carbene gold xanthate (NHC-Au-X, X - xanthate) complexes. These easily accessible complexes demonstrate significant versatility as photocatalysts, facilitating [2+2]-cycloadditions, and as π-catalysts in the intramolecular hydroxylation of allenes and hydrohydrazination of alkynes.

Three-quarters of the planet's land surface has been altered by humans, with consequences for animal ecology, movements and related ecosystem functioning. Species often occupy wide geographical ranges with contrasting human disturbance and environmental conditions, yet, limited data availability across species' ranges has constrained our understanding of how human pressure and resource availability jointly shape intraspecific variation of animal space use. Leveraging a unique dataset of 758 annual GPS movement trajectories from 375 brown bears (Ursus arctos) across the species' range in Europe, we investigated the effects of human pressure (i.

In this work a novel method for synthesis of 1,8-dihydroxynaphthalene melanin was presented, as well as the physicochemical properties, molecular structure, and characteristics of the pigment. The proposed synthesis protocol is simple and cost-effective with no enzymes or catalysts needed. The final product is not adsorbed on any surface, since the pigment is the result of autooxidation of 1,8-dihydroxynaphthalene.

The conflict on Poland's eastern border in particular raised concerns that the epidemiological situation in Poland would deteriorate due to the influx of immigrants from countries with a high incidence of MDR-TB and Beijing genotype.
Objectives: To assess the epidemiological situation of MDR-TB in Poland in 2018-2022 and to analyse the prevalence of the Beijing genotype in the Polish and immigrant populations.
