Objectives: To evaluate the efficacy of the head rotation test with bowing (B-HRT) in the sitting position in diagnosing lateral semicircular canal benign paroxysmal positional vertigo (LSC-BPPV).
Methods: The efficacy outcomes of lateralization of 25 patients with LSC-BPPV were prospectively evaluated using B-HRT. Traditional head toration in the supine position (S-HRT) and the bow and lean test were also assessed for comparative effectiveness.
Highly pathogenic avian influenza virus (HPAIv) H5N6 has destructive consequences on the global poultry production system. Recently, a growing number of layer farms have been heavily damaged from the HPAIv epidemic due to the increased virulence of the virus and the intensification of the production system. Therefore, stakeholders should implement effective preventive practices at the farm level that are aligned with contingency measures at the national level to minimize poultry losses.

- A large-area membrane-electrode assembly (MEA) was created using a methanol-based slurry of PtRu/C catalyst via a decal transfer method, emphasizing the importance of slurry stability for electrode integrity.
- The study evaluated various organic solvents for their effectiveness in maintaining stable catalyst slurries, finding that methanol provided the best dispersion and coating properties.
- The resulting MEA demonstrated superior performance compared to those made using spray methods and performed well even with a reforming gas, with an active area of 51.84 cm.

Methods: A retrospective cohort study of 269 HCC patients who underwent two or more pretreatment imaging studies of computed tomography or magnetic resonance imaging was performed. Tumor growth rate and TVDT were calculated by comparing tumor volumes between imaging studies.
