Fate mapping identifies the origin of SHF/AHF progenitors in the chick primitive streak [PDF]

, 2012
Heart development depends on the spatio-temporally regulated contribution of progenitor cells from the primary, secondary and anterior heart fields. Primary heart field (PHF) cells are first recruited to form a linear heart tube; later, they contribute ...

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Histopathologic Analysis of the Morpho‐Functional Zones of the Human Acetabular Labrum

Clinical Anatomy, EarlyView.
ABSTRACT The structural and functional adaptation of soft tissues to mechanical load controls their ability to withstand injury and influences their capacity for healing. Similar to the knee meniscus, the acetabular labrum exhibits zonal differences in mechanical load distribution, resulting in distinct regions with unique structural and functional ...

Testosterone selectively increases primary follicles in ovarian cortex grafted onto embryonic chick membranes: relevance to polycystic ovaries [PDF]

, 2008
Histological studies have demonstrated that polycystic ovaries (PCO) contain increased numbers of preantral follicles with a specific increase in primary follicles.

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Storage of Hatching Eggs : Effects of storage and early incubation conditions on egg characteristics, embryonic development, hatchability, and chicken quality [PDF]

, 2010
Key words: egg storage, embryonic development, albumen quality, hatchability, chick quality It is well known that an increase in the storage duration increases incubation duration and decreases hatchability and chick quality.

Assembly and Maintenance of Myofibrils in the Heart

Cytoskeleton, EarlyView.
ABSTRACT The assembly of actin and myosin to the paracrystalline arrangement of myofibrils in striated muscle, that is, heart and skeletal, has puzzled many a cell biologist. Different models, based on cultured cardiomyocytes, were proposed for the last 30 years to explain the sequence of events.

Climate Vulnerability and Sovereign ESG Performance: The Conditioning Roles of Adaptation Innovation, Institutional Quality and Robot Adoption

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The intensification of physical climate risk presents a critical question for global sustainability governance: does exposure to climate hazards strengthen or weaken a country's environmental, social and governance (ESG) performance? This study investigates the relationship between climate vulnerability and country‐level ESG performance across

Modelling growth of chick embryo

, 1994
An attenuated parabolic model has been proposed for determining the chick embryo weight depending on the time of incubation: Wem=0.00019119t^4.3482 exp(-0.052409t).

Purinergic and muscarinic modulation of the cell cycle and calcium signaling in the chick retinal ventricular zone [PDF]

, 2002
Spontaneous calcium transients occur in the ventricular zone of the chick retina and result from the endogenous release of neurotransmitters in the absence of action potentials.
