Germany was one of the first EU members to harmonize its legislation with the provisions of the European Union Directive no. 1023/2019 on preventive restructuring frameworks. The Law on Stabilization and Restructuring of Enterprises (StaRUG) introduced several new institutes through a modular approach with the aim of preventing insolvency. It entered into force on 1st January 2021 and provided a pre-bankruptcy procedure, as a novelty, rearranged procedure of personal administration of debtors in bankruptcy and the mediation procedure in restructuring. This enables business entities to timely determine the existence of circumstances that may jeopardize business, but also established the obligation to act appropriately in a timely manner. The instruments of the new legal framework are the adoption of the restructuring plan in court proceedings, the court examination of the contents of the restructuring plan, the court moratorium on executions and the court confirmation of the restructuring plan, as well as adoption of the plan in the mediation procedure. The aforementioned reform further strengthened the principles of consensualism in insolvency law. Also, this law represents a good model for other EU states and for candidate states in the process of harmonization of legislation with EU regulations as well. The aim of this paper is to provide an insight into the new institutes in German legislation, to analyze them and to give a critical review of their application in practice.

The Balkan Peninsula is identified as one of the major glacial refugia in Europe during the Pleistocene, and it has served as a genetic source for post-glacial recolonization for many temperate species. The aim of this study was to investigate the genetic diversity and phylogeographic patterns of the Mediterranean horseshoe bat, Rhinolophus euryale Blasius 1853, on the Balkan Peninsula. We also analyzed its demographic history and tested the hypothesis that this region was a glacial refugium for this species. We collected 82 samples from 20 localities in the Balkans and Italy and sequenced the mitochondrial D-loop region. Our results revealed low nucleotide but high haplotype diversity, with 20 out of 24 haplotypes reported for the first time. All Balkan and Italian samples belonged to a single genetic clade in the phylogenetic reconstruction, where they clustered together with previously published samples from Turkey, southern France and North Africa. The haplotype network had a star-like pattern that is indicative of recent population expansion. Both mismatch distribution and shallow genetic differentiation also supported the scenario of a sudden demographic expansion. We estimated that expansion within this lineage commenced in the Late Pleistocene. We suggest that the Balkan Peninsula was a glacial refugium for R. euryale.

Introduction/Objective. Amyotrophic lateral sclerosis (ALS) is a devastating motor neuron disease. The majority of cases are apparently sporadic ALS (SALS) with variants in susceptibility genes or sometimes in high-risk ALS genes. Two ALS susceptibility genes are SMN1, whose functional loss causes spinal muscular atrophy (SMA), and a nearly identical SMN2 gene, which modulates SMA severity. In this study we examined the association of copy number variations (CNVs) of SMN1 and SMN2 genes and two additional genes, SERF1 and NAIP, residing in the same genomic region (i.e. 5q13.2 segmental duplication), with SALS in patients from Serbia. Methods. Multiplex ligation-dependent probe amplification was used to determine CNVs of each gene in a clinically well-characterised group of 153 Serbian SALS patients and 153 controls. Results. Individual association between SMN1, SMN2, SERF1 or NAIP CNVs and SALS susceptibility or survival was not found. Survival curves based on the multivariable Cox regression analysis showed that three SMN1 copies, lower ALS Functional Rating Scale Revised (ALSFRS-R) score at the time of diagnosis, faster decline of the ALSFRS-R score over time, and shorter diagnostic delay result in shorter survival of Serbian SALS patients. Conclusion. Clinical variables might be complemented with the SMN1 copy number to improve prediction of survival in Serbian SALS patients.

Simulium reptans (Linnaeus, 1758) and Simulium reptantoides Carlsson, 1962 are two species of the Simulium reptans group whose distribution is unclear because of their confusing taxonomy and systematics. Their genetic variability is well known for populations in northern and central Europe and shows that both species have two forms; however, the genetic variability of these species in southern and eastern Europe is unknown. To identify the status of these two species in southeast Europe, mtDNA was extracted from 19 individuals from 12 localities across the Balkan Peninsula. Phylogenetic analysis confirmed the existence of two species with 7.38-7.94% divergence. Each species was comprised of two clades, with 2.31% and 1.43% interclade divergence for S. reptans and S. reptantoides, respectively. This study revealed the presence of both species across the Balkans and that S. reptans occurs in this area in only one form (S. reptans B), while S. reptantoides is found in two genetic forms (A and B).

The greatest epidemiological significance of leptospirosis in Europe comes from the fact that it is the most widespread zoonosis in the world. However, epizootiological data, especially information on maintenance hosts such as small wild mammals, are largely missing. To fill this gap in data in Serbia, we used RT-PCR for the detection of pathogenic Leptospira species and analysed 107 animals belonging to six species of small wild mammals (Apodemus agrarius, Apodemus flavicollis, Microtus arvalis, Myodes glareolus, Microtus subterraneus and Sorex araneus) collected from two localities. The animals from the first locality that was situated in a tourist area, were collected for four consecutive years (2014–2017). We found persistent incidence of infection from year to year ranging from 6.67% to 78.57%. The average frequency of infected animals was 33.3% with the highest frequency in 2014, the year characterised by a very high number of flooding days. All animals proved to be infected with pathogenic Leptospira species that were collected from the second locality situated in an agricultural area in a single year, 2014. The findings show a variable but constant presence of pathogenic Leptospira species in populations of small wild mammals in the studied areas, which indicates the need for constant monitoring.

Migratory behaviour, sociality and roost selection have a great impact on the population structure of one species. Many bat species live in groups, and movements between summer and hibernation sites are common in temperate bats. The Mediterranean horseshoe bat Rhinolophus euryale is a cave-dwelling species that exhibits roost philopatry and undertakes seasonal movements which are usually shorter than 50 km. Its distribution in Serbia is restricted to karstic areas in western and eastern parts of the country, with a lack of known roosts between them. In this study, microsatellite markers were used to evaluate genetic variation in this species in the Central Balkans. Specifically, spatial genetic structuring between geographic regions and relatedness within different colony types were assessed. All analysed loci were polymorphic, and there was no significant inbreeding coefficient recorded. A moderate degree of genetic differentiation among the sampled colonies was found, and significant isolation by distance was recorded. Our results revealed that populations show a tendency to segregate into three clusters. Unexpectedly, populations from Montenegro and Eastern Serbia tended to group into one cluster, while populations from Western Serbia and Slovenia represented second and third cluster, respectively. The majority of variance was partitioned within colonies, and only a small but significant portion among clusters. Average relatedness within colony members was close to zero, did not differ significantly between the different colony types, and kinship is unlikely to be a major grouping mechanism in this species.

Tryptophan hydroxylase 1 (TPH1) gene, coding for serotonin synthesizing enzyme, and recent stressful life events (SLEs) have been commonly associated with suicidal behavior. TPH1 has been also hypothesized to be involved in stress-response mechanisms. The aim of this study was to assess TPH1 variant rs1800532 and its possible interaction with recent SLEs as risk factors for suicide attempt (SA) in Serbian psychiatric patients, including 165 suicide attempters and 188 suicide nonattempters. rs1800532 and recent SLEs were independently associated with SA, while rs1800532 did not moderate the effect of recent SLEs on SA vulnerability among Serbian psychiatric patients.

Genetic background underlying wild populations immune response to different parasites is still not well understood. We studied immune response to multiple infections and to competition between different parasite species at different developmental stages in population of yellow-necked mouse, Apodemus flavicollis. Quantitative real-time PCR was used to investigate associations of MHC II-DRB, IL-10 and Tgf-β genes expressions with presence of intestinal parasites at different developmental stages. Furthermore, we were interested whether the host related characteristics (sex, age, body condition, presence of B chromosomes or expression of other genes) or characteristics of present parasites (number of adult parasites of each identified species, egg count of each parasite genus, total number of nematode individuals) affect differential expression of the studied genes. A significant invert association between the expression of MHC II-DRB and Tgf-β gene was found, which together with absence of IL-10 association confirmed modified Th2 as the main type of immune response to nematode infections. Effect of recorded parasites and parasite life-cycle stage on expression levels of MHC II-DRB gene was detected only through interactions with host-related characteristics such as sex, age, and the presence of B chromosomes. The presence of B chromosomes is associated with lower expression level of Tgf-β gene. Although the influence of host genetic background on parasite infection has already been well documented, this is the first study in mammals that gave presence of B chromosomes on immune response full consideration.
