Accuracy of digital subtraction radiography in combination with a contrast media in assessment of proximal caries depth

Journal of Dental Research, Dental Clinics, Dental Prospects, 2008
Background and aims. Radiography is used to diagnose the demineralization process and carious lesions; however, conventional radiography and direct digital images do not show these lesions when the amount of demineralization is less than 40%.

The velar chord and dynamic integration of the gular valve in crocodylians

The Anatomical Record, EarlyView.
Crocodilians have a unique gular valve that forms a seal between the oral cavity and the pharynx. The gular valve has traditionally been treated as two parts: a mobile ventral flap associated with the tongue and a fixed dorsal velum palatini. This work describes a connective tissue band, the velar chord, which functionally integrates the two parts of ...

Digital Radiography — Not If, but When

Journal of the California Dental Association, 1999
Digital radiography can enhance the dental practice by facilitating diagnosis, enabling orderly filing and archiving, and allowing better communication with patients. Although the initial investment in equipment is substantial, it is quickly repaid and provides both a substantive and fiscal benefit.

Association of Synovial Innate Immune Exhaustion With Worse Pain in Knee Osteoarthritis

Arthritis &Rheumatology, EarlyView.
Objective Uncontrolled pain remains a major clinical challenge in the management of knee osteoarthritis (OA), the most common disabling joint disease. Worse pain is associated with synovial innate immune cell infiltration (synovitis), but the role of innate immune‐regulatory cells in pain is unknown. Our objective was to identify synovial innate immune

A Curve-based Material Recognition Method in MeV Dual-energy X-ray Imaging System [PDF]

arXiv, 2014
High energy dual-energy X-ray Digital Radiography(DR) imaging is mainly used in material recognition of the cargo inspection. We introduce the development history and the principle of the technology and describe the data process flow of our system. The system corrects original data to get the dual-energy transparence image.

Effects of secukinumab on enthesiophyte and erosion progression in psoriatic arthritis –a one‐year double‐blind, randomized, placebo‐controlled trial utilizing high‐resolution peripheral quantitative computed tomography

Arthritis &Rheumatology, Accepted Article.
Objectives This study aimed to ascertain the effect of secukinumab on erosion and enthesiophyte progression in psoriatic arthritis (PsA) by high‐resolution peripheral quantitative computed tomography (HR‐pQCT). Methods This was a phase 4, double‐blind, randomized, placebo‐controlled trial.

First experimental research of low energy proton radiography [PDF]

arXiv, 2013
Proton radiography is a new scatheless diagnostic tool, and which provides a potential development direction for advanced hydrotesting. Recently a low energy proton radiography system has been developed at CAEP. This system has been designed to use 11MeV proton beam to radiograph thin static objects.

Lead‐free transparent nanocomposite for efficient clinical X‐ray shielding

BMEMat, EarlyView.
A lead‐free nanocomposite of LaF3 nanoparticles exhibits a high optical transparency of 86% with a heavy loading of up to 70 wt%, which enables the design of radiation shielding goggles for interventional surgeons in real clinical scenarios. Abstract The increasing use of X‐ray imaging in the medical field has generated a growing need for efficient ...
