Observation‐Only Management of Cervicofacial Nontuberculous Mycobacterial Lymphadenitis in Children

open access: yesThe Laryngoscope, EarlyView.
This is a retrospective study of immunocompetent children with nontuberculous mycobacterial cervicofacial lymphadenitis who were managed by observation. Kaplan–Meier‐estimated cumulative resolution was 82.8% by 12 months. Observation may be a safe, effective alternative to surgical excision for selected patients.

Dynamic Retinal Pathology in Glaucoma Progression Revealed by High‐Resolution Functional Imaging in Vivo

open access: yesLaser &Photonics Reviews, EarlyView.
In this work, we investigated the dynamic retinal pathology of glaucoma from onset to late stages through longitudinal in vivo high‐resolution imaging in a silicone oil‐induced ocular hypertension (SOHU) glaucoma mouse model. We developed an optimized adaptive optics two‐photon excitation fluorescence microscopy (AO‐TPEFM) technique for morphological ...

Study on the Shape Memory Performance of 4D‐Printed Auxetic Cellular Structures with Energy Absorption Application

open access: yesMacromolecular Materials and Engineering, EarlyView.
4D‐printed auxetic cellular structures made from PETG demonstrate almost complete recovery of shape and mechanical properties after repeated loading. Two strategies successfully addressed the low shape‐fixity issue, the primary limitation of cold programming.
