Special methods are required for computing information on biological objects under complex research. The DBASE3-PLUS system offers vast possibilities for working with large quantity of different sets of information in multi-aspect statistical analysis. Usefulness of this system for creation of and operation with the data on distribution of genetic and non-genetic traits in a population was shown by means of the special set of applied programs in the dBase language. An example presented is aimed at distinguishing those genetic markers which probably can influence common individual health of the members of population. Special regression procedure was suggested to divide the population sample into subgroups with different health levels. Significant differences in distribution of some genetic markers were demonstrated between healthy persons and those who were suffering from chronic diseases.

The demographic history of a population, and the distribution of fitness effects (DFE) of newly arising mutations in functional genomic regions, are fundamental factors dictating both genetic variation and evolutionary trajectories. Although both demographic and DFE inference has been performed extensively in humans, these approaches have generally either been limited to simple demographic models involving a single population, or, where a complex population history has been inferred, without accounting for the potentially confounding effects of selection at linked sites. Taking advantage of the coding-sparse nature of the genome, we propose a 2-step approach in which coalescent simulations are first used to infer a complex multi-population demographic model, utilizing large non-functional regions that are likely free from the effects of background selection.

Plant lipids are a diverse group of biomolecules that play essential roles in plant architecture, physiology, and signaling. To advance our understanding of plant biology and facilitate innovations in plant-based product development, we must have precise methods for the comprehensive analysis of plant lipids. Here, we present a comprehensive overview of current research investigating plant lipids, including their structures, metabolism, and functions.

Background: RAB11 is a small GTP-binding protein that regulates intracellular trafficking of recycling endosomes and is thereby involved in several neural functions. Highly similar RAB11 isoforms are encoded by RAB11A and RAB11B genes, and their pathogenic variants are associated with similar neurodevelopmental disorders, suggesting that RAB11A and RAB11B play similar and important roles in brain development. However, the detailed distribution patterns of these isoforms in various organs, including the brain, remain undetermined.

Antimicrobial resistance (AMR) is a major threat to global public health that continues to grow owing to selective pressure caused by the use and overuse of antimicrobial drugs. Resistance spread by plasmids is of special concern, as they can mediate a wide distribution of AMR genes, including those encoding extended-spectrum -lactamases (ESBLs). The CTX-M family of ESBLs has rapidly spread worldwide, playing a large role in the declining effectiveness of third-generation cephalosporins.

Large vertebrate genomes duplicate by activating tens of thousands of DNA replication origins, irregularly spaced along the genome. The spatial and temporal regulation of the replication process is not yet fully understood. To investigate the DNA replication dynamics, we developed a methodology called RepliCorr, which uses the spatial correlation between replication patterns observed on stretched single-molecule DNA obtained by either DNA combing or high-throughput optical mapping.
