Fluorescence‐Guided Detection of Perineural and Bony Invasion With Margin Correlation in Gingival Squamous Cell Carcinoma Using Panitumumab‐IRDye800

Head &Neck, EarlyView.
ABSTRACT Background Near‐infrared (NIR) fluorescence‐guided surgery using EGFR‐targeted tracers (e.g., panitumumab‐IRDye800CW) can provide real‐time visualization of tumors and margins in Head and Neck Squamous Cell Carcinoma. Prior studies have demonstrated its safety and potential to improve intraoperative decision‐making and margin assessment ...

Hyperemesis gravidarum and oral health: A scoping review

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Hyperemesis gravidarum (HG) is a severe form of nausea and vomiting in pregnancy (NVP), associated with dehydration, nutritional deficiencies, and systemic complications. Although recurrent vomiting, altered dietary patterns, and medication effects might plausibly affect oral health, this relationship has not been comprehensively ...

Holistic bone developing microenvironment engineered apoptotic extracellular vesicles recapitulate multidimensional developmental signatures in adult and senile bone repair

Interdisciplinary Medicine, EarlyView.
The developing bone was identified as an M2a‐like macrophage driven immune microenvironment with multidimensional developmental signatures. hME‐ApoEVs were successfully fabricated via stimulating the M2a‐like developing microenvironment in vitro and confirmed its recapitulation of developmental features.

Research on optimization design of helical gear tooth profile modification

AIP Advances
Under real-world working conditions, the performance of gears is affected by manufacturing errors, installation errors, load deformation, and other factors. Shock, vibration, and noise are inevitable in the operation of meshing gears. Gear tooth profile can be appropriately modified to improve the smoothness of the transmission and improve the mesh ...
