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.

Measurement of Egg Yolk Color by Means of the Colorimeter

Poultry Science, 1949
Abstract THE color of the yolk of egg has received considerable attention for it is known to affect the desirability of the egg. A yolk that is either too highly colored or too pale is objectionable. Palmer (1915) (1919) reported that specific feeds affected the color of the egg yolk and that the color was due almost entirely to the pigment ...

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 ...

The Effect of Seaweed Carotenoids on Egg Yolk Coloration

Poultry Science, 1963
Abstract CONTRADICTORY records are found in the literature on the effect upon egg yolk coloration of feeding seaweed meal to the laying hen. While Olsson (1941) and Black (1953) observed little or no effect, Hoie and Sannan (1960) found a significant darkening of the egg yolk on addition of 5 percent of seaweed meal to the rations.

Advanced Functional Materials for Marine Energy Utilization

Interdisciplinary Materials, EarlyView.
Marine renewable energy is an important future clean energy supply. We construct and sort out the material system for marine energy capture and conversion, transmission, storage, and utilization for the first time. ABSTRACT Several features of marine energy, including large reserves, sustainable utilization, environmental friendliness, make it a ...

Tracking the Pulse of the Dunes: Seasonal Metabolic Responses of Liolaemus arambarensis to Climatic Variability

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Seasonal environmental fluctuations profoundly influence ectothermic vertebrates, regulating their physiology, metabolism, and life cycles. This study investigated the metabolic and morphometric seasonal dynamics of the subtropical sand lizard Liolaemus arambarensis, an endangered species endemic to the coastal dunes of southern Brazil.

The influence of laying hens' diet enriched with omega-3 fatty acids, paprika and marigold on physical properties of eggs [PDF]

Journal on Processing and Energy in Agriculture, 2016
The aim of the present paper was to evaluate basic physical parameters of laying hen eggs, which were fed by the diet containing co-extruded linseed and sunflower meal, as a source of omega-3 fatty acids, as well as paprika and marigold flower, as ...

Development of an Efficient and Scalable Process for Preparing Timolol N‐Nitrosamine Impurities B, C, E, H, I, J, and Their ADMET Evaluation

Journal of Heterocyclic Chemistry, EarlyView.
N‐nitrosamine impurities (B, C, E, H, I, J) of timolol maleate are easily synthesized from diethyl malonate and 3,4‐dichloro‐1,2,5‐thiadiazole. Good yields and precise impurity profiling are made possible by the effective technique, which also ensures pharmaceutical safety and strengthens regulatory compliance.

Application of Conductivity Combined with Various Other Instrumental Analyses in the Detection of the Freshness and Yolk-to-White Ratio of Liquid Egg [PDF]

Shipin Kexue
This study established a rapid and efficient technique to detect the freshness and yolk-to-white ratio of liquid egg based on conductivity combined with salinity, total dissolved solids (TDS), pH, and color parameters. The results showed that during the
