Effect of Uniformity of Eggshell Thickness on Eggshell Quality in Chickens
The Journal of Poultry Science, 2014 Numerous parameters have been proposed to evaluate eggshell quality in order to reduce losses from damaged eggshells. The uniformity of eggshell thickness (UET), as a newly proposed parameter, is defined as the reciprocal of the coefficient of variation

Eggshell colour differences in a classic example of coevolved eggshell mimicry
Biology Letters, 2023 Avian brood parasitism is a model system for understanding coevolutionary arms races, and the great reed warbler ( Acrocephalus arundinaceus , hereafter ‘warbler’) and its parasite the common cuckoo ( Cuculus canorus , hereafter ‘cuckoo’) are prime ...

Microwave Irradiation of Nanohydroxyapatite from Chicken Eggshells and Duck Eggshells [PDF]
The Scientific World Journal, 2014 Due to similarity in composition to the mineral component of bones and human hard tissues, hydroxyapatite with chemical formula Ca10(PO4)6(OH)2has been widely used in medical field. Both chicken and duck eggshells are mainly composed of calcium carbonate. An attempt has been made to fabricate nanohydroxyapatite (nHA) by chicken (CES) and duck eggshells

Evolution of the Avian Eggshell Biomineralization Protein Toolkit – New Insights From Multi-Omics
Frontiers in Genetics, 2021 The avian eggshell is a remarkable biomineral, which is essential for avian reproduction; its properties permit embryonic development in the desiccating terrestrial environment, and moreover, are critically important to preserve unfertilized egg quality ...

Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells
Advanced Healthcare Materials, EarlyView.Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.
