ABSTRACT Chitinase‐3‐like‐1 (CHI3L1, also known as YKL‐40) has been recognized as a biomarker of inflammation and tissue remodeling and has now emerged as a pseudoenzymatic immune checkpoint. Recent structural, immunological, and translational studies redefine it as an active regulator of immune suppression rather than a passive disease marker. Despite

Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.

Volumetric Modulated Arc Therapy for lung cancer: Correlation between dose and volume
Abstract Background In lung cancer radiotherapy, the volume of the lung receiving a dose above 20 Gy (V20Gy) and the mean lung dose are widely recognized dosimetric indicators for predicting radiation pneumonitis. However, there is currently no unified model to predict the minimum achievable values of V20Gy and mean lung dose.

Abstract Background An accurate assessment of the radiotherapy plans requires an accurate dose to the target and efficient confinement of the doses. However, present indices do not completely cover these aspects in a single framework. Purpose To develop a unified, dimensionless metric that integrates geometric conformity and dosimetric efficiency for ...

Abstract Background RapidArc Dynamic (RAD; Varian Medical Systems, Palo Alto, CA) is a novel volumetric modulated arc therapy (VMAT) technique that features dynamic collimator rotation synchronized with gantry rotation. RAD enables the use of static angle‐modulated ports (STAMPs) defined by user selected gantry and collimator angles.

Abstract Background Current Lattice radiation therapy (LRT) mainly uses inverse IMRT/VMAT optimization, which is time‐consuming and complex; however the high modulation complexity compromises dosimetric accuracy and blurs the peak‑to‑valley dose ratio.
