Bidirectional Expression of Metabolic, Structural, and Immune Pathways in Early Myopia and Hyperopia

open access: yesFrontiers in Neuroscience, 2016
Myopia (short-sightedness) affects 1.45 billion people worldwide, many of whom will develop sight-threatening secondary disorders. Myopic eyes are characterized by excessive size while hyperopic (long-sighted) eyes are typically small. The biological and

p38 Mitogen-activated Protein Kinase Regulates Oscillation of Chick Pineal Circadian Clock [PDF]

open access: yes, 2003
Extracellular signal-regulated kinase (ERK) and p38 are members of the mitogen-activated protein kinase (MAPK) family, and in some cases these kinases serve for closely related cellular functions within a cell. In a wide range of animal clock structures,

Cerberus is a feedback inhibitor of Nodal asymmetric signaling in the chick embryo [PDF]

open access: yes, 2007
The TGF-beta-related molecule Nodal plays an essential and conserved role in left-right patterning of the vertebrate embryo. Previous reports have shown that the zebrafish and mouse Cerberus-related proteins Charon and Cerberus-like-2 (Cerl-2 ...

Effect of Short-Term Thermal Conditioning on Physiological and Behavioral Responses to Subsequent Acute Heat Exposure in Chicks

open access: yesThe Journal of Poultry Science, 2014
It is known that thermal conditioning at an early age results in improved heat tolerance, and reduces mortality when re-exposed to heat in later life in chickens. However, the mechanism of thermal conditioning is not fully understood.

Chick Hippocampal Formation Displays Subdivision- and Layer-Selective Expression Patterns of Serotonin Receptor Subfamily Genes

open access: yesFrontiers in Physiology, 2022
Hippocampal formation (HF) plays a key role in cognitive and emotional processing in mammals. In HF neural circuits, serotonin receptors (5-HTRs) modulate functions related to cognition and emotion. To understand the phylogenetic continuity of the neural

Ethical euthanasia and short-term anesthesia of the chick embryo.

open access: yesALTEX, 2015
Fertilized chicken eggs are suggested as an alternative to mammalian models. The chorioallantoic membrane (CAM) of the chick embryo is widely used for examination of angiogenesis, xenotransplants and for virus production.

Intracerebroventricular Injection of Ghrelin Induces Sleep-Like Behavior in Neonatal Chicks

open access: yesThe Journal of Poultry Science, 2001
Ghrelin, a novel growth hormone (GH)-releasing acylated peptide, is recently isolated from rat stomach. This peptide stimulates the release of GH from the anterior pituitary through the GH secretagogue receptor and feeding in the rat.
