Analysis of the obliteration of the root canal: an investigation with Micro-CT [PDF]

Revista de Odontologia da UNESP
Introduction Traumatized teeth may undergo calcific metamorphosis of the pulp, a factor which makes endodontic treatment difficult due to the total or partial obliteration of the root canal. Objective To compare the existence of root canal lumen between

Gold nanoparticles for X-ray microtomography of neurons.

ACS Chemical Neuroscience, 2019
Commonly used methods to visualize the biological structure of brain tissues at subcellular resolution are confocal microscopy and two-photon microscopy. Both require slicing the sample into sections of a few tens of micrometers.

The mechanism of eutectic growth in highly anisotropic materials

Nature Communications, 2016
The origins of non-periodic growth features observed in irregular eutectics have been a source of controversy. Here authors use time-resolved X-ray microtomography during eutectic growth of an alloy to show how competing models can be extended and ...

3D multiscale imaging of human vocal folds using synchrotron X-ray microtomography in phase retrieval mode

Scientific Reports, 2018
Human vocal folds possess outstanding abilities to endure large, reversible deformations and to vibrate up to more than thousand cycles per second. This unique performance mainly results from their complex specific 3D and multiscale structure, which is ...

Greater Resistance to Drought‐Induced Embolism Is Linked to Higher Yield Maintenance in Soybean

Plant, Cell &Environment, EarlyView.
ABSTRACT With increasing drought events worldwide, crop breeding must focus on drought resistance to maintain crop yields. To ensure a high level of gas exchange and growth, plants need to maintain the integrity of their vascular system under drought conditions. While the impact of drought‐induced vascular damage on tree species is well‐documented, its

Investigating microarchitectural characteristics of woven bone exposed to ionizing radiation: comparative analysis of two segmentation methods and their impact on trabecular measurements in an animal study

Bioscience Journal
The study aimed to evaluate bone formation in surgical defects exposed to ionizing radiation (IR) and to compare two image segmentation methods: manual and standardized delimitation of the region-of-interest (ROI). Bone defects were created in the tibias

X‐ray Microtomography of Intermittency in Multiphase Flow at Steady State Using a Differential Imaging Method

Water Resources Research, 2017
We imaged the steady state flow of brine and decane in Bentheimer sandstone. We devised an experimental method based on differential imaging to examine how flow rate impacts impact the pore‐scale distribution of fluids during coinjection.
