Osteohistological evidence for terrestrial adaptation and an extended growth period in mekosuchine crocodylians and its potential role in their extinction

The Anatomical Record, EarlyView.
Abstract The Australasian crocodylian fossil record is dominated by the extinct endemic clade Mekosuchinae, with known members spanning the Eocene‐to‐Holocene. This diverse clade exhibited high morphological disparity, from early members superficially similar to Crocodylus, to more terrestrial forms later in the clade's evolutionary history.

Exploring student perceptions of integrating mixed reality with cadaveric teaching in undergraduate neuroanatomy education: A qualitative study

Anatomical Sciences Education, EarlyView.
Abstract Mixed reality (MR) using head‐mounted displays provides three‐dimensional visualizations that have been suggested to enhance learning when used alongside conventional anatomy teaching in medical education. This study explored student perceptions of the integration of MR and traditional cadaveric learning, and their optimal delivery to support ...

Numerical simulation of the blood flow behavior in the circle of Willis [PDF]

BioImpacts, 2014
Introduction: This paper represents the numerical simulation of blood flow in the circle of Willis (CoW). Circle of Willis is responsible for the oxygenated blood distribution into the cerebral mass.

Microsurgery for aneurysms on the circle of Willis.

South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde, 1974
A description of a microsurgical approach for aneurysms on the anterior part of the circle of Willis is given. Certain practical points are stressed. The operative results obtained in 37 consecutive aneurysms operated on in 30 patients are discussed.S. Afr. Med. J., 48, 825 (1974).

Chromatin Conformation Links Putative Enhancers in Intracranial Aneurysm–Associated Regions to Potential Candidate Genes

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background We previously showed that intracranial aneurysm (IA)–associated single‐nucleotide polymorphisms are enriched in promoters and putative enhancers identified in the human circle of Willis, on which IAs develop, suggesting a role for promoters ...

The hows and whys—A new teaching model for anatomy learning supported by customized 3D printed models

Anatomical Sciences Education, EarlyView.
Abstract The advent of three‐dimensional (3D) printing technology has enabled educators to design customized 3D printed models (3DPMs), but the current literature shows conflicting evidence regarding the impact of 3DPMs on students' knowledge acquisition.

Topology‐aware anatomical segmentation of the Circle of Willis: HUNet unveils the vascular network

IET Image Processing
This research investigates the Circle of Willis, a critical vascular structure vital for cerebral blood supply. A modified novel dual‐pathway multi‐scale hierarchical upsampling network (HUNet) is presented, tailored explicitly for accurate segmentation ...

pH Determination in Grape Must by Benchtop NMR Spectroscopy

ChemFoodChem, EarlyView.
Benchtop NMR spectroscopy enables electrode‐free pH determination in grape must. By modeling tartaric acid's chemical shift variation, pH is derived directly from NMR spectra alongside standard composition parameters. Validated against 100 samples, this integrated approach tracks pH changes during acidification, deacidification, and fermentation ...

The circle of Willis (1621-75) [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 2000
It is easily forgotten that in the century of Shakespeare and Marlowe there was no scientific or rational physiology as we now understand these disciplines. The era was of magic and witchcraft; insubstantial notions of the spiritus animalis were rife, and irrational speculation abounded.

Aneurysmal parent artery-specific inflow conditions for complete and incomplete circle of willis configurations [PDF]

, 2018
BACKGROUND AND PURPOSE: Hemodynamics are thought to play a role in intracranial aneurysm growth and rupture. Computational fluid dynamics is frequently performed to assess intra-aneurysmal hemodynamics, using generalized flow waveforms of healthy ...
