Studies of Egg Yolk Pigmentation

, 1968
THE nature of the carotenoid pigments (xanthophylls) which are deposited in the beak, shank and adipose tissues of chickens and in the yolks of eggs, the methods of their measurement, and the effects of antioxidants upon their utilization, have been ...

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

Environmental 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.

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

Integrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae

Acta Zoologica, EarlyView.
ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...

Recurrent Modification of a Conserved Cis-Regulatory Element Underlies Fruit Fly Pigmentation Diversity [PDF]

, 2013
The development of morphological traits occurs through the collective action of networks of genes connected at the level of gene expression. As any node in a network may be a target of evolutionary change, the recurrent targeting of the same node would ...
