Eye‐Tracking Analysis in Surface‐Guided Radiation Therapy Positioning: A Comparative Study of Experienced and Novice Radiation Therapists

Journal of Medical Radiation Sciences, EarlyView.
This study compared expert and novice radiation therapists during surface‐guided radiation therapy (SGRT) setup for head and neck cases using eye tracking. Experts exhibited fewer gaze fixations and concentrated on specific screens during the latter half of positioning, suggesting that they efficiently identified key positioning points.

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

Laser &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 ...

Step‐Ladder Bioprinting to Align Collagen Fibers for Anisotropic Tissue Fabrication

Small, EarlyView.
The step‐ladder printing platform includes successive segments of channels with varying widths in a custom barrel design. This design allows for improved anisotropy of collagen fibers during extrusion. To demonstrate its effectiveness, corneal constructs with high transparency and shape fidelity, as well as articular cartilage constructs, displaying ...

Single‐cell RNA sequencing revealed the T‐cell heterogeneity and exhaustion subsets of Helicobacter pylori‐induced gastritis‐to‐cancer transformation

VIEW, EarlyView.
H. pylori infection is a major cause of stomach cancer, but its effect on immune cells in tumors is unclear. Using single‐cell sequencing, we mapped the stomach tumor environment and discovered a specific exhausted T‐cell subtype, marked by the FYB1 gene, that is abundant in H. pylori‐positive tumors and linked to patient prognosis. Our findings reveal

Polarization vision and the physiological basis for trichromatic vision in Philaenus spumarius: Understanding host‐seeking behaviour in insect vectors for Xylella fastidiosa control

Annals of Applied Biology, EarlyView.
We investigated the role of vision in host‐seeking behaviour by Philaenus spumarius, the main European vector of Xylella fastidiosa, through an integrated anatomical, optical, physiological, and behavioural study. Our data highlight that the spittlebug uses visual cues, including polarized light, which may aid in detecting the polarized reflections ...
