Objective: This study aims to evaluate the feasibility and utility of a novel, open-source 3D printed simulator for practicing laryngeal surgery skills in the clinic setting.
Study Design: Device development and validation.
Setting: A tertiary medical center.
Methods: A laryngeal surgery simulator was created using computer-aided design software and 3D printed. Ten otolaryngology residents completed exercises utilizing the simulator and a flexible video laryngoscope for visualization. The training involved 3 microsurgery tasks: (1) suture removal from simulated vocal cords, (2) removal of silicone vocal cord polyps, and (3) simulated flap creation by peeling a grape's skin. Participant demographics, task completion time, and video recordings were collected. Participants provided subjective feedback through 5-point Likert-style questions assessing content and face validity.
Results: Both novice and experienced otolaryngology resident physicians reported positive perceptions of the simulator and its efficacy as an educational device, with average agreement more than neutral ( < .01). Participants praised the simulator's utility for practicing microsurgery skills using a flexible video laryngoscope and for handling instruments such as Kleinsasser forceps and micro scissors ( < .01). Preliminary findings suggest improvements in task completion time with higher post-graduate year. Participants also reported the need for greater realism.
Conclusion: This study of a 3D-printed simulator for laryngeal surgery skills using a flexible video laryngoscope demonstrated promising utility as an educational device. Positive feedback reflects the potential value as a training tool for residents to practice fine motor skills required for laryngeal surgery. Further research with larger sample sizes is needed to validate these findings.

The application of large language models in materials science has opened new avenues for accelerating materials development. Building on this advancement, we propose a novel framework leveraging large language models to optimize experimental procedures for synthesizing quantum dot materials with multiple desired properties. Our framework integrates the synthesis protocol generation model and the property prediction model, both fine-tuned on open-source large language models using parameter-efficient training techniques with in-house synthesis protocol data.

Zebrafish have gained prominence as a model organism in neuroscience over the past several decades, generating key insight into the development and functioning of the vertebrate brain. However, techniques for whole brain mapping in adult stage zebrafish are lacking. Here, we describe a pipeline built using open-source tools for whole-brain activity mapping in adult zebrafish.

Breast cancer remains a significant global health challenge due to its complexity, which arises from multiple genetic and epigenetic mutations that originate in normal breast tissue. Traditional machine learning models often fall short in addressing the intricate gene interactions that complicate drug design and treatment strategies. In contrast, our study introduces GEMDiff, a novel computational workflow leveraging a diffusion model to bridge the gene expression states between normal and tumor conditions.

To unravel the mechanism of immune activation and suppression within tumors, a critical step is to identify transcriptional signals governing cell-cell communication between tumor and immune/stromal cells in the tumor microenvironment. Central to this communication are interactions between secreted ligands and cell-surface receptors, creating a highly connected signaling network among cells. Recent advancements in in situ-omics profiling, particularly spatial transcriptomic (ST) technology, provide unique opportunities to directly characterize ligand-receptor signaling networks that power cell-cell communication.
