NUMERICAL ANALYSIS OF DYNAMICAL SYSTEMS AND THEIR STRUCTURAL STABILITY

open access: yesÌнформаційні технології в освіті, 2015
The method for investigating the dynamics of concrete systems of small dimension and obtaining strict results is demonstrated on the example of M. Henon’s system.

Interplay between RNA‐protein interactions and RNA structures in gene regulation

open access: yesFEBS Open Bio, EarlyView.
Methodological advances in mapping transcriptome‐wide RNA‐protein interactions and RNA structures have started to uncover the potential of RNP conformations in gene regulation. Competing RNA–RNA, RNA‐protein and protein–protein interactions shape the compaction and function of RNPs throughout their lifetime and may provide novel therapeutic targets in ...

Tryptophan metabolite atlas uncovers organ, age, and sex‐specific variations

open access: yesFEBS Open Bio, EarlyView.
Tryptophan metabolites were analyzed across twelve organs, the central nervous system, and serum in male and female mice at three life stages. We found tissue‐, sex‐, and age‐specific differences, including increased indole‐3‐pyruvate and kynurenine in aging males.

Production of antibacterial compounds by a Steely hybrid polyketide synthase in Dictyostelium

open access: yesFEBS Open Bio, EarlyView.
By selecting appropriate production species under optimised culture conditions, new chlorinated dibenzofuran compounds, which previously could not be analysed in sufficient quantities, were identified from cellular slime mould fruiting bodies. The strong antibacterial activity exhibited by these compounds suggests a link to the ecological function of ...

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms

open access: yesFEBS Open Bio, EarlyView.
We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

What is an attractor?

open access: yes, 2021
En este artículo discutiremos principalmente sobre los sistemas dinámicos y la noción de atractor, un concepto importante que nos permite obtener mucha información sobre el comportamiento de los sistemas dinámicos. Los primeros capítulos están dedicados principalmente a dar la definición de ambos conceptos, así como algunas de sus propiedades más ...

Overview of molecular signatures of senescence and associated resources: pros and cons

open access: yesFEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...
