Mechanisms and kinetic assays of aminoacyl‐tRNA synthetases

open access: yesFEBS Letters, EarlyView.
Accurate protein synthesis is crucial for life. The key players are aminoacyl‐tRNA synthetases (AARSs), which read the genetic code by pairing cognate amino acids and tRNAs. AARSs establish high amino acid selectivity by employing physicochemical limits in molecular recognition.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Categories of categories

open access: yes, 2007
A certain amount of category theory is developed in an arbitrary finitely complete category with a factorization system on it, playing the role of the comprehensive factorization system on Cat. Those aspects related to the concepts of finality (in particular terminal objects), discreteness and components, representability, colimits and universal arrows,

The category of Bratteli diagrams

open access: yes, 2014
A category structure for Bratteli diagrams is proposed and a functor from the category of AF algebras to the category of Bratteli diagrams is constructed.

From omics to AI—mapping the pathogenic pathways in type 2 diabetes

open access: yesFEBS Letters, EarlyView.
Integrating multi‐omics data with AI‐based modelling (unsupervised and supervised machine learning) identify optimal patient clusters, informing AI‐driven accurate risk stratification. Digital twins simulate individual trajectories in real time, guiding precision medicine by matching patients to targeted therapies.

The derived category of an exact category

open access: yesJournal of Algebra, 1990
For a saturated (i.e. every idempotent splits) exact category \(\mathcal E\) the derived category \(D({\mathcal E})\) is constructed as the quotient of the homotopy category of chain complexes of objects of \(\mathcal E\), by the full subcategory of acyclic complexes.

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

Entrepreneurship and business activity: content of categories

open access: yesВісник Житомирського державного технологічного університету: Серія: економіка, управління та адміністрування, 2019
For further development of the theory of entrepreneurship and the operationalization of its concepts, it is important to clarify the content of its fundamental categories «entrepreneurship» and «business activity».
