Cytotoxic and genotoxic response of an in vitro model of human fetal ventricular cardiomyocytes RL-14 in interaction with pH-dependent high molecular weight Gold-based chitosan nanoparticles

OpenNano
The use of chitosan in the green synthesis of metal nanoparticles influences biological recognition processes, which depend on the synthesis conditions, including pH value, temperature, and reaction time.

Heat drastically alters floral color and pigment composition without affecting flower conspicuousness

American Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.

The Effect of Different Hydroxyapatite Structures on the Cellular Behavior of Polycaprolactone/Sodium Alginate/Collagen Scaffolds to Proliferate Mesenchymal Cells

Surface and Interface Analysis, Volume 58, Issue 1, Page 28-34, January 2026.
ABSTRACT This study demonstrates how a hydroxyapatite/(HaP) structure influences and determines cell viability/proliferation on electrospun hybrid polycaprolactone/sodium‐alginate/collagen scaffolds when mesenchymal cells are seeded. Four different HaPs were tested: (1) nanometric/(nHaP), (2) micrometric/(μHap), (3) functionalized/(nHaPf), and (4 ...

Zymoseptoria tritici stealth infection is facilitated by stage‐specific downregulation of a β‐glucanase

New Phytologist, Volume 248, Issue 6, Page 3191-3207, December 2025.
Summary Plant cell walls constitute a major defence barrier against pathogens, although it is unclear how specific cell wall components impact pathogen colonisation. Pathogens secrete cell wall‐degrading enzymes (CWDEs) to facilitate plant colonisation, but damaged or infected cells are often a source of cell wall‐derived oligosaccharides that trigger ...
