Silkworm pupa oil attenuates acetaminophen‐induced acute liver injury by inhibiting oxidative stress‐mediated NF‐κB signaling

open access: yesFood Science & Nutrition, 2019
Acetaminophen (APAP) overdose causes severe hepatotoxicity and acute liver failure. The current study aims to investigate the protection effects of silkworm pupa oil (SPO) against acute hepatic injury in APAP‐exposed Kunming mice. Our results showed that

Small-misorientation toughness in biominerals evolved convergently [PDF]

open access: yesarXiv, 2021
The hardest materials in living organisms are biologically grown crystalline minerals, or biominerals, which are also incredibly fracture-tough. Biomineral mesostructure includes size, shape, spatial arrangement, and crystal orientation of crystallites, observable at the mesoscale (10 nanometer - 10 micron).

Evidence for a liquid precursor to biomineral formation [PDF]

open access: yesarXiv, 2021
The crystals in animal biominerals such as sea urchin spines, mollusk shells, and coral skeletons, form by attachment of amorphous particles that subsequently crystallize. Do these solid amorphous precursor particles have liquid precursors? Polymer-induced liquid precursors (PILP), or prenucleation clusters coalescing into a liquid precursor to calcium
