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 ...

Balancing mechanics and metabolism: Elevational variation in the microanatomy of hummingbird flight muscle

The Anatomical Record, EarlyView.
Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

The Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Axons morphometry in the human spinal cord

, 2018
Due to the technical challenges of large-scale microscopy and analysis, to date only limited knowledge has been made available about axon morphometry (diameter, shape, myelin thickness, density), thereby limiting our understanding of neuronal ...

Brain maps of general cognitive functioning: neuroimaging and neurobiological signatures

Translational Psychiatry
In this paper, we attempt to answer two questions: 1) which regions of the human brain, in terms of morphometry, are most strongly related to individual differences in domain-general cognitive functioning (g)?

Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

The Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

Quantitative Analysis of the Rat Testes after an Acute Cadmium and Diazinon Administration

Scientific Papers Animal Science and Biotechnologies, 2023
Changes in the rat testes caused by cadmium and organophosphate insecticide diazinon were evaluated using the morphometry methods. 36 hours after an single intraperitoneal administration of cadmium at a dose of 2 mg/kg b.w., diazinon 20 mg/kg b.w., and ...

Multifunctional polycaprolactone‐based composite fibers with icariin and glutathione for effective repair of critical‐sized bone defects

BMEMat, EarlyView.
A multifunctional PCL‐based scaffold co‐delivering Icariin and Glutathione synergistically enhances osteogenesis, angiogenesis, and oxidative stress resistance, achieving near‐complete repair of critical‐sized bone defects in vivo. This cell‐free platform represents a promising strategy for accelerated bone regeneration.
