4D-analysis of left ventricular heart cycle using procrustes motion analysis.

PLoS ONE, 2014
The aim of this study is to investigate human left ventricular heart morphological changes in time among 17 healthy subjects. Preliminarily, 2 patients with volumetric overload due to aortic insufficiency were added to our analyses.

Dogs from the past: Exploring morphology in mandibles from Iberian archaeological sites using 3D geometric morphometrics

We describe the shape variability of nine dog hemimandibles recovered from two Holocene archaeological sites on the Iberian Peninsula. In this study we mainly focus on the Chalcolithic age dog remains recovered from Barrio del Castillo (Torrejón de Ardoz,

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

The Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Integrating whole‐bone and regional analyses to understand human scapular growth

The Anatomical Record, EarlyView.
Abstract This study investigates ontogenetic changes in human scapular morphology using three‐dimensional geometric morphometrics with whole‐bone and region‐specific analyses. The aim is to evaluate whether the scapula follows a regular developmental pattern and whether its functionally distinct components, the scapular spine (SS) and glenoid fossa ...

Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients

The Anatomical Record, EarlyView.
Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

The Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).

Does 3D Phenotyping Yield Substantial Insights in the Genetics of the Mouse Mandible Shape?

G3: Genes, Genomes, Genetics, 2016
We describe the application of high-resolution 3D microcomputed tomography, together with 3D landmarks and geometric morphometrics, to validate and further improve previous quantitative genetic studies that reported QTL responsible for variation in the ...

Heterodonty in the teeth of the turiasaurian sauropod from Angeac-Charente (Early Cretaceous, southwestern France): Comparison of anatomical and geometric morphometric approaches. [PDF]

J Anat
Turiasaurian teeth from Angeac‐Charente exhibit five dental morphotypes and reveal clear heterodonty and anteroposterior size gradient. Qualitative comparative anatomy quickly and efficiently identifies morphotypes, while 3D geometric morphometrics combined with machine learning refine ambiguous cases, demonstrating that qualitative and quantitative ...
