    Predicting gut microbiota dynamics in obese individuals from cross-sectional data by Ena Melvan, Ena Melvan, Andrew P. Allen, Tea Vuckovic, Irena Soljic, Antonio Starcevic

    Published 2025-06-01
    “…While gut microbiota has been linked to obesity, most research has focused on static taxonomic composition rather than the dynamic interactions between microbial taxa.MethodsWe applied BEEM-Static, a generalized Lotka-Volterra model, to cross-sectional 16S rRNA gut microbiome data from six public datasets, comprising 2,435 profiles from lean and obese individuals.ResultsA total of 57 significant microbial interactions were identified in obese individuals (79% negative), compared to 37 in lean individuals (92% negative). …”

    Theoretical study on the effect of carbon graphenous nanoclusters on the stability and capacity of polyamide in a nanocomposite by E. M. Demianenko, M. I. Теrets, Yu. I. Sementsov, S. M. Makhno, V. S. Kuts, A. G. Grebenyuk, M. T. Kartel

    Published 2019-11-01
    “…The less value of the interaction energy (-325.0  kJ/mol) for the nanocomposite with C96H24 species is due to the insufficient size of the selected model for the graphene matrix. The analysis of the hydrogen bond lengths between the oxygen atom of carbonyl group and hydrogen one of amino group indicates that, regardless of length of linkage of the polymeric chain of polyamide (monomer and dimer) and the size of the graphene-like matrix (C96H24 and C110H26) in the nanocomposite, the hydrogen bond in composites is shorter in comparison with a those values in complexes without a carbon matrix. …”
