Article Synopsis
- Maternal immunoglobulin Y (IgY) is crucial for providing passive immunity to newly-hatched chicks through a two-step transfer process from the mother's blood to the yolk and then to the embryo.
- Research indicated that the FcRY receptor is vital for transferring IgY from blood to yolk and plays a significant role in the uptake of IgY into egg yolks, with variations in amino acid residues affecting transport efficiency.
- The study also demonstrated that neutralizing FcRY antibodies significantly reduce IgY transport, suggesting that FcRY not only facilitates IgY transfer but also prolongs its half-life in the bloodstream, highlighting its multifunctional role in avian immunity.
Polypyrrole-encapsulated platinum nanoparticles (PPy/Pt-NPs) prepared by an easy single-step sonochemical synthesis were used as catalysts for the liquid phase hydrogenation of substituted alkenes in methanol or methanol/water mixtures. Polypyrrole (PPy) coatings on the nanoparticles were able to act as nanoscopic filters for substrates molecules, and consequently substrate selectivity could be controlled in the catalytic processes.
