An efficient scheme for modeling peptide toxicity is proposed and applied. The peptide cytotoxicity is calculated in the form of a mathematical function of its constituent amino acids, represented by single-symbol abbreviations. It was found that considering the so-called fragments of local symmetry can significantly increase the predictive potential of the proposed models. The best model gives for validation set value of Matthews correlation coefficient 0.7 on the set of 2784 peptides. The prospects for applying the ideas of infodynamics to research activities related to modeling the biochemical behavior of peptides are discussed.

Chemical detergents are extensively used to remove pesticide residues and foodborne pathogens on fresh fruits, but their residues are toxic to humans. To address this issue, a dual-functional starch copolymer, specifically dialdehyde starch-grafted ε-polylysine copolymer (DIA-ε-PL starch), was synthesized utilizing native starch with surfactant properties and the natural antimicrobial cationic peptide ε-polylysine (ε-PL). The effectiveness of DIA-ε-PL starch as a fruit detergent was subsequently evaluated.

The structural specificity of organic nitrogen sources in modulating cyanobacterial physiology and toxin production remains poorly understood. This study systematically evaluated the bioavailability of exogenous glycine peptides in Microcystis aeruginosa (M. aeruginosa) and their regulatory roles in algal growth and microcystins (MCs) synthesis through an integrated physiological and transcriptomic approach.

The scorpion Hottentotta judaicus inhabits the Levant region of the Middle East, including Lebanon, Jordan, Palestine, and Israel. While previous research focused on its insecticidal properties and sodium-channel-targeting toxins, its venom remains largely unexplored using modern proteomic approaches. We analyzed the venom composition of H.

Colorectal cancer (CRC) remains a major global health burden, necessitating more effective and selective therapeutic approaches. Nanocarrier-based drug delivery systems offer significant advantages by enhancing drug accumulation in tumors, reducing off-target toxicity, and overcoming resistance mechanisms. This review provides a comprehensive overview of recent advancements in nanocarriers for CRC therapy, including passive targeting the enhanced permeability and retention (EPR) effect, and active targeting strategies that exploit specific tumor markers using ligands such as antibodies, peptides, and aptamers.
