Egg shape changes at the theropod–bird transition, and a morphometric study of amniote eggs [PDF]

open access: yes, 2014
The eggs of amniotes exhibit a remarkable variety of shapes, from spherical to elongate and from symmetrical to asymmetrical. We examine eggshell geometry in a diverse sample of fossil and living amniotes using geometric morphometrics and linear ...

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

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

open access: yesEnvironmental 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 ...

Observations on the physiological development of trout eggs [Translation from: Roux. Arch. f. Entwicklungsmechanik der Organismen, 114. 771, 1929] [PDF]

open access: yes, 1929
The osmotic pressure of the perivitelline fluid and the yolk of trout (Salmo trutta) eggs were measured separately by the Drucker-Schrein method. The permeability of the egg membrane and the variations in the osmotic pressure of the eggs when placed in ...

Mechanism of Alfalfa in Enhancing Goose Egg Yolk Flavor: An Analysis Based on Metabolomics and Quantitative Lipidomics

open access: yesFood Frontiers, EarlyView.
ABSTRACT Organic egg production requires daily provision of coarse feed, fresh or dried forage, and silage to poultry. This study employed flavoromics, metabolomics, and quantitative lipidomics to investigate the effects of replacing 0% (CK), 10% (T10), and 20% (T20) of the basal diet of laying geese with alfalfa (Medicago sativa L.) on the sensory ...
