Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

open access: yesGeological Journal, EarlyView.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Thermochronologic Constraints on the Extensional History of the Ibex Hills, Southeastern Black Mountains, Death Valley, California

open access: yesGeological Journal, EarlyView.
A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

New Approach Methodologies (NAMs) in Alternative Methods: A Comparative Cytotoxicity Analysis of Nanostructured Hydroxyapatite in Adipose Stem Cells Spheroids

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Toxicological assessment is essential in NP approval for health and medical applications. Although 2D cell culture has been widely used, 3D models, especially spheroids, provide better predictive value for toxicological risk assessments since they replicate complex cellular interactions more accurately.

Titanium migration and bone response in loaded osseointegrated implants: ESEM‐EDX analysis in Macaca fascicularis

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Titanium nanoparticle (TP) migration into peri‐implant bone may influence osseointegration. It remains unclear how loading protocols may affect TP distribution. This study aimed to detect TP in the bone around implants undergoing different loading protocols in Macaca fascicularis.

Comparative efficacy of novel bioactive glass versus sodium fluoride toothpaste for dentin hypersensitivity

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This first‐in‐human clinical study aimed to evaluate the safety and efficacy of a bioglass incorporated in a toothpaste, in reducing dentin hypersensitivity (DH) compared to a sodium fluoride (NaF) toothpaste over a 2‐week period. Methods A double‐blind, randomized, parallel‐arm, proof‐of‐concept clinical trial was conducted with 46

Current Trends and Future Prospects of Integrating Electrospinning With 3D Printing Techniques for Mimicking Bone Extracellular Matrix Scaffolds

open access: yesJournal of Polymer Science, Volume 63, Issue 6, Page 1481-1504, 15 March 2025.
ABSTRACT This article presents a review of the recent findings on the combination of electrospun nanofibers and three‐dimensional (3D)‐printed structures for extracellular matrix (ECM) scaffolds for bone tissue engineering. We explore the synergy between electrospinning (ES), which produces highly porous, fibrous structures from materials like collagen
