Purpose: Vital dyes allow the visualization of cells in vivo without causing tissue damage, making them a useful tool for studying lateral line and inner ear hair cells in living zebrafish and other vertebrates. FM1-43, YO-PRO-1, and DASPEI are three vital dyes commonly used for hair cell visualization. While it has been established that FM1-43 enters hair cells of zebrafish and other organisms through the mechanoelectrical transduction (MET) channel, the mechanism of entry into hair cells for YO-PRO-1 and DASPEI has not been established despite widespread use.

- The posterior cervical triangle is crucial for understanding the spread of head and neck cancers, particularly skin cancers of the scalp, and requires a thorough knowledge of the neurovascular structures there.
- Traditional 2D anatomical diagrams don't effectively convey the important spatial relationships needed for successful surgery, prompting the creation of a 3D virtual model.
- This study involved segmenting musculature and neurovasculature from a CT scan and reviewing literature to yield an anatomically accurate 3D model, which will be available online for educational purposes.
Several imaging modalities are utilized in the diagnosis, treatment, and surveillance of head and neck cancer. First-line imaging remains computed tomography (CT); however, MRI, PET with CT (PET/CT), and ultrasound are often used. In the last decade, several new imaging modalities have been developed that have the potential to improve early detection, modify treatment, decrease treatment morbidity, and augment surveillance.

- The study aimed to compare clinical outcomes in patients who had a history of tobacco use against those who didn't, specifically focusing on Zenker's diverticulotomy (ZD).
- A total of 424 patients were reviewed, finding that 34.4% had a history of tobacco use, yet no significant differences in postoperative complications or recurrence rates were linked to smoking status.
- Despite the study's limitations, it suggested that while non-smokers had longer times to recurrence, the differences weren't statistically significant, indicating more research is needed in this area.
