Colloidal-gold Immunocytochemical Localization of Osteopontin in Avian Eggshell Gland and Eggshell [PDF]

Journal of Histochemistry & Cytochemistry, 2008
During mineralization of the avian eggshell, there is a sequential and orderly deposition of both matrix and mineral phases. Therefore, the eggshell is an excellent model for studying matrix–mineral relationships and the regulation of mineralization. Osteopontin, as an inhibitor of crystal growth, potently influences the formation of calcium phosphate

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...

Two cis-regulatory SNPs upstream of ABCG2 synergistically cause the blue eggshell phenotype in the duck.

PLoS Genetics, 2020
Avian eggshell color is an interesting genetic trait. Here, we report that the blue eggshell color of the domestic duck is caused by two cis-regulatory G to A transitions upstream of ABCG2, which encodes an efflux transporter.

Perceptions of Racial, Ethnic, and Cultural Ruptures in Counseling: A Qualitative Case Study of a Client From a Minoritized Background

Journal of Counseling &Development, EarlyView.
ABSTRACT Ruptures resulting from racial microaggressions occurring during treatment have a negative impact on clients from minoritized backgrounds. Although racial microaggressions are widely understood as offensive comments targeting one's race, scholars maintain that not broaching or avoiding discussions regarding the client's race, ethnicity, and ...

Extracellular Matrix Molecules of the Eggshell as Related to Eggshell Quality [PDF]

, 1997
The extracellular matrix of the mineralizing eggshell contains molecules hypothesized to be regulators biomineralization. To study eggshell matrix molecules, a bank of monoclonal antibodies was generated that bound demineralized eggshell matrix or localized to oviduct epithelium.

Elevating Testosterone and Androstenedione Produces Temporary Sex‐Dependent Variation in Japanese Quail (Coturnix japonica) Embryonic Development

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Vertebrate growth rates may respond to maternally supplied steroids, yet injections of individual hormones into avian eggs of different species have produced inconsistent results. This might be because diverse steroids' concentrations are naturally correlated in yolks, injections are not elevating hormones at critical times in development, or ...
