In four samples (T101, SL50V, CP2, MVU2-21), the presence of satellite CMV RNA was identified along with CMV. The SL50V variant, characterized by a divergent RNA2 sequence, potentially represents a reassortant variant. Based on a BLAST search and phylogenetic analysis, the Slovak CMV isolates can be divided into two genetically different Groups, Ia and II, respectively. Of these, three variants originated from the Papaveraceae species (oilseed poppy, common poppy and great celandine), previously poorly described as CMV natural hosts. Using high-throughput sequencing, we have characterized near complete genomes of 14 Slovak CMV variants from different plant hosts. The combination of Se with substances attenuating adenosine neurotransmission may become a new therapeutic strategy for patients with depression.Ĭucumber mosaic virus (CMV Cucumovirus, Bromoviridae) is an omnipresent virus characterized by a large host range and high genetic variability. Molecular studies also showed changes in the expression of the Slc6a15, Comt, and Adora1 genes, particularly after exposure to the combination of Se and DPCPX, which indicates a beneficial effect and may help to explain the key mechanism of the antidepressant effect. However, we observed a decrease in the mRNA level of antioxidant defense enzymes. Our research revealed that neither DPCPX, IST, nor Se or combinations of the tested substances induced significant changes in the brain-derived neurotrophic factor (BDNF) levels in mice serum vs. Further experiments demonstrated that Se (0.25 mg/kg) significantly enhanced the activity of mice in both tests when co-administered with DPCPX (1 mg/kg) and IST (0.5 mg/kg) at doses which would be ineffective if administered individually. The results confirmed that, when administered by itself, Se exerts an antidepressant-like effect in the FST and TST and that this activity is dose-dependent. Biochemical studies were performed to elucidate the action mechanisms of the investigated treatment strategies. The main goal of this study was to determine the antidepressant-like potential of the co-administration of sodium selenite (Se) and the selective adenosine A1 and A2A antagonists DPCPX and istradefylline (IST), respectively, in mice despair tests. An empirical study using real-world road networks demonstrates the superiority and scalability of MOFA compared to a conventional solution. Therefore, MOFA retrieves candidate facilities only once for the query segment and computes valid segments using these candidate facilities, thereby avoiding the repeated retrieval of candidate facilities when the query point moves. Each valid segment has the same k facilities farthest from the query locations in the valid segment. To this end, this study proposes a moving farthest search algorithm (MOFA) to compute valid segments for the query segment in which the query point is located.

The main challenge in processing M kFN queries in road networks is avoiding the repeated retrieval of candidate facilities as the query point arbitrarily moves along the road network. This study considers the moving k-farthest neighbor (M kFN) query that constantly retrieves the k facilities farthest from a moving query point q in a road network. Given a set of facilities F and a query point q, a k-farthest neighbor ( kFN) query returns the k farthest facilities f 1, f 1, ⋯, f k from q.
