Protein constituents of the eggshell: eggshell-specific matrix proteins
Cellular and Molecular Life Sciences, 2009In this article, we review the results of recent proteomic and genomic analyses of eggshell matrix proteins and draw attention to the impact of these data on current understanding of eggshell formation and function. Eggshell-specific matrix proteins from avian (ovocleidins and ovocalyxins) and non-avian (paleovaterin) shells are discussed. Two possible

Identification and localization of lysozyme as a component of eggshell membranes and eggshell matrix
Matrix Biology, 2000The avian eggshell is a composite biomaterial composed of non-calcifying eggshell membranes and the overlying calcified shell matrix. The calcified shell forms in a uterine fluid where the concentration of different protein species varies between the initial, rapid calcification and terminal phases of eggshell deposition.

Eggshell Aspiration in Infants
Archives of Pediatrics & Adolescent Medicine, 1975Two infants inhaled eggshell fragments. The first aspirated a small fragment into the upper part of the trachea and resuscitation attempts resulted in descent of the foreign body to the right lower lobe bronchus. Two attempts at bronchoscopy were unsuccessful and spontaneous disintegration occurred.

Blus, Gish, Belisle and Prouty allege that DDE causes eggshell thinning in brown pelicans and that the relationship is logarithmic1. In support of their conclusion that a cause and effect relationship between DDE and shell thinning exists, they offer as evidence Wiemeyer and Porter's2 work with kestrels.

Relationship between eggshell strength and keratan sulfate of eggshell membranes
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2007Eggshell strength is an important factor in an effort to minimize eggshell breakage, which is a significant problem in the egg production industry. In the current study, we isolated and quantified the specific glycosaminoglycans (GAGs) from the calcified eggshell and shell membranes, which are related to eggshell strength.

Value-added Uses of Eggshell and Eggshell Membranes
2019The chicken egg is a crucial source of high-quality human nutrition. Massive numbers of eggs are produced annually with a significant proportion (30%) being processed in industrial breaking plants, leading to the accumulation of eggshell (ES) and eggshell membrane (ESM) waste.

Morphogenesis of the eggshells in Drosophila
2000The Drosophila eggshell is a specialized extracellular matrix that forms between the oocyte and overlaying somatic follicle cells during the latter stages of oogenesis. Largely proteinaceous, the eggshell is a highly organized multilayered structure with regional specializations designed to perform a variety of functions.
