H Nuclear Magnetic Resonance relaxometry has been applied to reveal dynamical properties of water molecules embedded into egg yolk and white of three species: turkey, chicken and quail. Two fractions of water molecules, referred to as confined-water and free-water fractions, have been revealed. It has been demonstrated that translation diffusion of the confined-water fraction is three-dimensional. The dynamics of the confined-water has been quantitatively described in terms of diffusion coefficients and rotational correlation times. The parameters have been compared for egg yolk and white for all the species. In addition to these quantities, the number of the confined-water molecules per unit volume has been provided for all cases. The obtained parameters provide insight into the dynamics of water in eggs of different origin and allow to identify similarities and differences between them in connection to the structure of the network formed by the macromolecular fraction of egg yolk and white.
Platypuses are a unique freshwater mammal native to eastern Australia. They are semi-aquatic, predominantly nocturnal, and nest in burrows dug into the banks of waterbodies. Quantifying nesting burrow characteristics is challenging due to the species' cryptic nature.

This study explored the impact of varying alkalinity levels in pH-shifting treatments on egg yolk protein (EYP) emulsification and investigated the underlying oil-water interface adsorption mechanism. Increasing alkaline pH-shifting treatment exposed more hydrophobic groups within EYP, altering its tertiary structure. Moreover, pH-shifting treatment reduced solution particle size (P < 0.
* Preventative measures, accurate diagnosis, and effective treatments are crucial to controlling COVID-19, and specific antibodies are key for treating patients and preventing new infections.
* Research indicates avian egg yolk contains natural antibodies (IgY) that can identify and neutralize SARS-CoV-2, suggesting that egg yolk could serve as a cost-effective and readily available source for developing diagnostics and therapies.
Salted duck eggs are a popular food in China and a key ingredient in pastries such as mooncakes, valued for their unique flavors. In this study, we examined the influence of brining processes on duck eggs, focusing on salt concentration and the effect of added wine. Four experimental groups were established: 18% salt, 25% salt, and 18% or 25% salt with added wine.
Carotenoids from different sources have different structures and functions, and their dietary components benefit the health of various organisms. The effects of halophilic Archaea-derived C50 carotenoids on poultry egg quality and gut microbiota remain largely unexplored. In this study, we isolated a carotenoid-secreting strain of , TRM89021, from the Pamir Plateau.
