Advanced Science, EarlyView.TPP‐SAT, a mitochondria‐targeted natural enzyme‐cascade nanogel, selectively scavenges mitochondrial ROS (e.g., H2O2/·O2⁻) and converts them into therapeutic O2 via enzymatic cascades, alleviating hypoxia and inflammation. It rebalances M1/M2 macrophage polarization, activates the Nrf2 pathway while suppressing NF‐κB, enhances antioxidant defenses, and

Study on Virtual Gear Hobbing Simulation and Gear Tooth Surface Accuracy [PDF]
arXiv, 2023 This paper presents a digital simulation method for the hobbing process of cylindrical gears. Based on the gear generation principle, taking the professional software as the tool, the problem of virtual hobbing simulation on involute helical gears was studied, and the virtual hobbing simulation of hobbing on the whole gear was completed by using macros

The comparison of different rapid maxillary expansion devices from periodontal tissue health and root resorption perspectives [PDF]
, 2017 INTRODUCTION: Utilization of rapid maxillary expansion (RME) is common for the correction of sagittal discrepancies in orthodontic treatment. RME appliances will transmit a compressive force to the periodontal support structures. This resultant force can

CTooth: A Fully Annotated 3D Dataset and Benchmark for Tooth Volume Segmentation on Cone Beam Computed Tomography Images [PDF]
arXiv, 2022 3D tooth segmentation is a prerequisite for computer-aided dental diagnosis and treatment. However, segmenting all tooth regions manually is subjective and time-consuming. Recently, deep learning-based segmentation methods produce convincing results and reduce manual annotation efforts, but it requires a large quantity of ground truth for training.

Tooth morphometry using quasi-conformal theory [PDF]
Pattern Recognition 99, 107064 (2020), 2019 Shape analysis is important in anthropology, bioarchaeology and forensic science for interpreting useful information from human remains. In particular, teeth are morphologically stable and hence well-suited for shape analysis. In this work, we propose a framework for tooth morphometry using quasi-conformal theory.

Non uniformity: structural strategy for optimizing functionality in skeletal ligaments [PDF]
, 2017 Ligaments serve as compliant connectors between hard tissues. In that role, they function under various load regimes and directions. However, the 3D structure of ligaments is still considered uniform.

Reassessment of Xenodens calminechari with a discussion of tooth morphology in mosasaurs
The Anatomical Record, EarlyView.Abstract Xenodens calminechari is a mosasaurid taxon named by Longrich et al. (2021) based on the holotype MHNM.KH.331, a left maxilla with several teeth. This holotype was obtained nonscientifically (without technical supervision) from an area in Morocco that yields many manipulated or forged specimens. Examination of Longrich et al.
