Finite element modelling and load share analysis for involute worm gears with localised tooth contact [PDF]

, 2001
A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the

Transient Displacement Response to Pulse Excitations on Periodontal Tissues [PDF]

, 1988
In the field of dental study it is most fundamental and necessary to estimate the condition of periodontium. In order to examine a mechanical characteristics of periodontium, the theoretical displacement response to periodontal mechanical model (three ...

Wearable Bioelectronics for Home‐Based Monitoring and Treatment of Muscle Atrophy

Advanced Science, EarlyView.
As an inevitable disease, muscle atrophy has received more attention. Because the factors that induce this disease are diverse, achieving a complete cure is still impossible. Wearable bioelectronics provides a more comfortable, low‐cost, and efficient way of home care for the monitoring and treatment of muscle atrophy. Therefore, this review summarizes

In Situ Valence Engineering of Copper Silicate Nanozymes with Enhanced Peroxidase‐Like Catalytic Activity for Oral Disease Detection

Advanced Science, EarlyView.
A novel copper silicate nanozyme (CSHSs‐Ar) with high peroxidase‐like catalytic activity and great catalytic specificity is well developed using a facile in situ valence‐engineered approach. The well‐developed CSHSs‐Ar nanozyme‐involved system can be utilized and employed as an efficient colorimetric sensor for the detection of volatile sulfur ...

Fate of HERS during tooth root development

Developmental Biology, 2009
Tooth root development begins after the completion of crown formation in mammals. Previous studies have shown that Hertwig's epithelial root sheath (HERS) plays an important role in root development, but the fate of HERS has remained unknown. In order to investigate the morphological fate and analyze the dynamic movement of HERS cells in vivo, we ...

Toward a Species Search Engine: KISSE Offers a Rigorous Statistical Framework for Bone Collagen Tandem Mass Spectrometry Data

Advanced Science, EarlyView.
The Species Search Engine (KISSE) is a novel statistical approach for identifying species from collagen peptides, using a curated library of sequences and their relative abundances derived from shotgun proteomics. Abstract DNA and bone collagen are two key sources of resilient molecular markers used to identify species from their remains.

Influence of linear profile modification and loading conditions on the dynamic tooth load and stress of high contact ratio gears [PDF]

A computer simulation for the dynamic response of high-contact-ratio spur gear transmissions is presented. High contact ratio gears have the potential to produce lower dynamic tooth loads and minimum root stress but they can be sensitive to tooth profile

Additive Manufactured Magnetoelectric Wireless Retainer as the Periodontal Remodeler for Post‐Orthodontic Tissue Reconstruction and Relapse‐Inhibition

Advanced Science, EarlyView.
Orthodontic relapse persists as a 120‐year challenge, as traditional retainers fail to remodel tissue, causing lifelong dependence. This study demonstrates a flexible magnetoelectric retainer (FMOR) enabling wireless periodontal remodeling. FMOR cues shift periodontal ligament cell (PDLC) paracrine signaling, promoting M2 macrophages, osteogenic ...

LPS‐Induced Mitochondrial Damage via SLC41A1‐Mediated Magnesium Ion Efflux Leads to the Pyroptosis of Dental Stem Cells

Advanced Science, EarlyView.
Lipopolysaccharide induces upregulation of the magnesium (Mg2+) efflux transporter solute carrier family 41 member 1 in dental stem cells, leading to a decrease in intracellular Mg2+ concentration and promoting the binding of oligomycin sensitivity‐conferring protein and cyclophilinD.
