Cardiac morphological and morphometric analysis of Ardea alba
The Anatomical Record, EarlyView.Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

The 9+ month marathon: How pregnancy may have shaped human endurance capacities
The Anatomical Record, EarlyView.Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

Viruses, 2022 The rabies virus is widely distributed and vaccines are an important strategy to prevent its spread. The whole-genome sequences of rabies strains in relation to vaccine development provide essential information to maintain vaccine quality and develop new

Humans and platyrrhines share a pattern of articular variance
The Anatomical Record, EarlyView.Abstract Previous work has identified a pattern of articular shape variation in modern human limb joints, in which convex joint surfaces exhibit constrained variance relative to their more variable concave conarticulars. This pattern is notable given that joint morphogenesis is influenced by local biomechanical environments, which vary substantially ...

Insulin Hypoglycemia in Chick Embryos.
Experimental Biology and Medicine, 1948 Landauer1, 2 has found that certain morphological abnormalities may be produced by injecting insulin into the yolk of 0-5-day chick embryos. In the course of an investigation into the carbohydrate metabolism of insulin-treated embryos we have found that a persistent hypoglycemia is produced by insulin applied in this manner.

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 ...

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.

Developmental Changes in Action Potential Prolongation by K+-Channel Blockers in Chick Myocardium
Journal of Pharmacological Sciences, 2011 The effects of K+-channel blockers on the action potential duration of the myocardium were examined in isolated right ventricles from the 7 – 10-day-old, 11 – 13-day-old, and 14 – 20-day-old embryo and 1 – 7-day-old hatched chicks.

Chick Embryo Culture and Electroporation [PDF]
Current Protocols in Cell Biology, 2012 AbstractImportant events in embryonic development such as gastrulation, neurulation, and cranial neural crest development occur in ectodermal tissues during vertebrate embryonic development. Although the chicken embryo is a well‐established model system in developmental biology, problems of accessibility of the ectoderm for experimental manipulation ...
