High hydrostatic pressure modulates the digestive properties of rice starch-gallic acid composites by boosting non-inclusion complexation.

Influencing the starch postprandial glycemia via interventions that are sourced from natural plant materials has gained attention recently. Amylose present in starch is reported to form complexes with small ligands such as gallic acid (GA) through a conformational change that are digested slowly and contribute to the formation of resistant starch. In this study, the molecular interactions, multi-scale structure and in vitro digestion properties of normal neat rice starch and rice starch-GA composites (2, 5 % w/v) obtained either by high hydrostatic pressure (HHP) or thermal (T) treatment were compared.

Molecular characterization, transcriptional profiling, and antioxidant activity assessment of nucleoredoxin (NXN) as a novel member of thioredoxin from red-lip mullet (Planiliza haematocheilus).

Nucleoredoxin (NXN) is a prominent oxidoreductase enzyme, classified under the thioredoxin family, and plays a pivotal role in regulating cellular redox homeostasis. Although the functional characterization of NXN has been extensively studied in mammals, its role in fish remains relatively unexplored. In this study, the NXN gene from Planiliza haematocheilus (PhNXN) was molecularly and functionally characterized using in silico tools, expression analyses, and in vitro assays.

Functional characterization of peroxiredoxin 5 from yellowtail clownfish (Amphiprion clarkii): Immunological expression assessment, antioxidant activities, heavy metal detoxification, and nitrosative stress mitigation.

Peroxiredoxin 5 (Prdx5) is the last recognized member of Prdx family. It is a unique, atypical, 2-Cys antioxidant enzyme, protecting cells from death caused by reactive oxygen species (ROS). In this study, the Prdx5 ortholog of Amphiprion clarkii (AcPrdx5) was identified and characterized to explore its specific structural features and functional properties.

Sublethal Damage Caused by Cold Plasma on Cells: Impact on Cell Viability and Biofilm-Forming Capacity.

The group represents a serious risk in powdered and amylaceous foodstuffs. Cold plasma (the fourth state of matter) is emerging as an alternative effective nonthermal technology for pasteurizing a wide range of matrices in solid, liquid, and powder form. The present study aims to evaluate the mechanisms involved in inactivation via cold plasma, focusing on (i) the technology's ability to generate damage in cells (at the morphological and molecular levels) and (ii) studying the effectiveness of cold plasma in biofilm mitigation through the direct effect and inhibition of the biofilm-forming capacity of sublethally damaged cells post-treatment.
