The effect of different wavelengths of light during incubation on the development of rhythmic pineal melatonin biosynthesis in chick embryos

Animal, 2019
Rhythmic pineal melatonin biosynthesis develops in chick embryos incubated under a light (L)-dark (D) cycle of polychromatic white light. The spectral sensitivity of the embryonic pineal gland is not known and was investigated in this study.

Post‐hatching development of the remote‐tactile bill‐tip organ in precocial shorebirds (Scolopacidae)

Journal of Anatomy, EarlyView.
Juvenile scolopacid shorebirds possess well‐developed osteological correlates of tactile bill‐tip organs, indicating sensory systems for remote‐touch foraging are present from early life. Ontogenetic changes in bill‐tip morphology suggest ecological specialisation and interspecific variation develop later, after fledging in these highly precocial ...

Inheritance and Establishment of Gut Microbiota in Chickens

Frontiers in Microbiology, 2017
In mammals, the microbiota can be transmitted from the placenta, uterus, and vagina of the mother to the infant. Unlike mammals, development of the avian embryo is a process isolated from the mother and thus in the avian embryo the gut microbial ...

RNA interference is ineffective as a routine method for gene silencing in chick embryos as monitored by fgf8 silencing.

, 2013
The in vivo accessibility of the chick embryo makes it a favoured model system for experimental developmental biology. Although the range of available techniques now extends to miss-expression of genes through in ovo electroporation, it remains difficult

Maternal Dietary Inflammatory Index and Biomarkers of Inflammation at Birth

Maternal &Child Nutrition, EarlyView.
ABSTRACT We evaluated the association between the inflammatory potential of the maternal diet during pregnancy and levels of inflammatory biomarkers measured in cord blood and maternal serum at birth. Dietary inflammatory potential was calculated using the energy‐adjusted dietary inflammatory index (E‐DII) in the French EDEN and ELFE birth cohorts ...

Applications of In Ovo Technique for the Optimal Development of the Gastrointestinal Tract and the Potential Influence on the Establishment of its Microbiome in Poultry

Frontiers in Veterinary Science, 2016
As the current poultry production system stands, there is a period of time that newly hatched chicks are prevented from access to feed for approximately 48 to 72 hours.

Passive hyperthermia increases blood circulation in specific regions, largely independent of conduit artery mechanics and cardiac performance

Experimental Physiology, EarlyView.
Abstract Passive hyperthermia increases net peripheral and systemic blood flow in humans and other animals, yet the underlying haemodynamic forces that selectively accelerate blood movement remain incompletely characterized. Wave intensity analysis offers insight into the respective contributions of the heart and the vascular system to changes in blood

Evaluation of chicken embryo extract and egg yolk extract as alternatives to basic cell culture medium supplement

BMC Research Notes
Background Fetal calf serum (FCS), an existing cell culture supplement, is effective but has several drawbacks, including being expensive, requiring a lengthy process of production, and requiring a hard currency. With this in mind, we planned to evaluate

Unveiling a New Link: Cholesterol Deficiency in Smith–Lemli–Opitz and Niemann–Pick C as a Driver of Ciliopathies

American Journal of Medical Genetics Part A, Volume 200, Issue 6, Page 1179-1191, June 2026.
ABSTRACT The ciliopathies are a group of genetic disorders caused by defective function of either the primary cilia (a large number) or the motile cilia (a much smaller number). These have been defined as diseases with mutations in genes encoding individual ciliary or cilia‐associated proteins.

Isoleucine at position 137 of haemagglutinin acts as a mammalian adaptation marker of H9N2 avian influenza virus

Emerging Microbes and Infections
The H9N2 subtype of avian influenza virus (AIV) is widely distributed among poultry and wild birds and is also a threat to humans. During AIV active surveillance in Liaoning province from 2015 to 2016, we identified 10 H9N2 strains exhibiting different ...
