Integrative Computational and Experimental Approaches Reveal the Protective Role of Moderate Caffeine Intake Against Apical Periodontitis Induced Bone Loss

International Endodontic Journal, EarlyView.
ABSTRACT Aim To investigate whether moderate systemic caffeine intake modulates the progression of apical periodontitis (AP) and associated alveolar bone loss, combining in vivo rat experiments with in silico molecular docking to explore potential mechanisms. Methodology Male Wistar rats were randomly assigned to four groups (n = 8 per group): control,

3D MULTI-SCALE SEGMENTATION OF GRANULAR MATERIALS

Image Analysis and Stereology, 2011
On a microscopic scale, a pyrotechnic material is made of a polymer matrix containing grains with different sizes and shapes. Its physical behaviour can be predicted by homogenization.

Advances in synchrotron radiation microtomography

Scripta Materialia, 2006
Abstract The use of synchrotron radiation X-ray microtomography rests on the exploitation of the beam coherence, the high spatial (submicron) or temporal resolution (s), in situ and real time experiments and quantitative measurements. Selected original applications showing these capabilities are presented.

Unravelling the skin of the nurse shark: A morphological description of the placoid scales of Ginglymostoma cirratum

Journal of Fish Biology, EarlyView.
Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

X-ray phase-contrast microscopy and microtomography

Optics Express, 2003
In-line phase contrast enables weakly absorbing specimens to be imaged successfully with x-rays, and greatly enhances the visibility of fine scale structure in more strongly absorbing specimens. This type of phase contrast requires a spatially coherent beam, a condition that can be met by a microfocus x-ray source. We have developed an x-ray microscope,

Evaluation of the accuracy of digital workflow for implant‐supported full‐arch fixed dental prostheses using a novel micro‐CT measurement technique

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aims to evaluate the accuracy of fit of full‐arch implant titanium frameworks fabricated from a fully digital workflow using a novel micro‐CT measurement technique. Materials and Methods A 3D‐printed model with four implant analogs was fabricated.

An anatomical study of the subarachnoid space surrounding the trigeminal ganglion in horses—in preparation for a controlled glycerol rhizotomy in equids

Frontiers in Veterinary Science
IntroductionEquine trigeminal-mediated headshaking is a painful neuropathic disorder comparable to trigeminal neuralgia in humans. The selective destruction of pain fibers within the trigeminal ganglion, called rhizotomy, is the surgical treatment of ...

A microCT Study of Three-Dimensional Patterns of Biomineralization in Pig Molars

Frontiers in Physiology, 2018
Domestic pig molars provide an interesting system to study the biomineralization process. The large size, thick enamel and complex crown morphology make pig molars relatively similar to human molars.
