Retinoid-related orphan receptor-γ (RORγ) is a nuclear receptor that plays important roles in the development and activation of T helper type-17 (Th17) cells. In this study, we characterized the pharmacological profile of JTE-151 ((4S)-6-[(2-chloro-4-methylphenyl)amino]-4-{4-cyclopropyl-5-[cis-3-(2,2-dimethylpropyl)cyclobutyl]isoxazol-3yl}-6-oxohexanoic acid), which is a novel RORγ antagonist identified by our group. JTE-151 dissociated co-activator peptide from the human RORγ-ligand binding domain (LBD) and recruited co-repressor peptide into human RORγ-LBD, and potently inhibited the transcriptional activity of RORγ of human, mouse and rat.

Symptoms of digital eye strain include blurred vision, dry eyes, eyestrain, neck and back ache, diplopia, light sensitivity, and headaches. Vergence or accommodation-related symptoms include blurred near or distance vision, difficulty refocusing, and diplopia.

Poor upper limb ergonomic positioning during robotic surgery occurs when the shoulders are abducted, and the elbows are lifted off the console armrest. The validated rapid upper limb assessment can quantify ergonomic efficacy.

Continuous video footage of 24 consecutive robotic colorectal surgery cases were analysed concurrently with sagittal video recordings of surgeon hand positions. Separated sagittal hand positions would indicate nonergonomic positioning without clutching of the robotic controls, either matching the on-screen up/down instrument tip positions (no VPM) or in the opposite direction (true VPM).

Cognitive workload (CWL) involves use of working memory (mental strain and effort) to complete a task. The three types of cognitive loads have been divided into intrinsic (dependent on complexity and expertise), extraneous (the presentation of tasks) and germane (the learning process) components.
