Accuracy of complete-arch dental impressions: a new method of measuring trueness and precision [PDF]

, 2013
STATEMENT OF PROBLEM: A new approach to both 3-dimensional (3D) trueness and precision is necessary to assess the accuracy of intraoral digital impressions and compare them to conventionally acquired impressions.

Evaluation of 3D Facial Scanners: Trueness & Precision

Aim This paper evaluates the precision and trueness of facial scanners (FSs) by analyzing facial scans from ten 3D scanners, consisting of five professional devices and five mobile applications. Material and Methods A 3D facial model with human-like dimensions, shape, and proportions, featuring reference points, was used to standardize measurements.

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Arginine methylation as a regulatory ratchet in cancer: From substrate selection to malignant‐state stabilization

Molecular Oncology, EarlyView.
Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

A comparative evaluation of intraoral and extraoral digital impressions: An in vivo study

The Journal of Indian Prosthodontic Society, 2018
Aim: The accuracy of a dental impression is determined by two factors: “trueness” and “precision.” The scanners used in dentistry are relatively new in market, and very few studies have compared the “precision” and “trueness” of intraoral scanner with ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Trueness of intraoral scanners: Its impact on the trueness and marginal and internal discrepancies of fabricated crowns (A comparative in vitro study)

Abstract Background Digital dentistry is constantly growing, and the availability of IOSs has significantly increased in recent years. Numerous studies have investigated the accuracy of different intraoral scanners; however, limited evidence is available concerning the effects of the accuracy of IOSs on the fit of zirconia crowns.
