SOX2, JAGGED1, β-Catenin, and Vitamin D Receptor Expression Patterns during Early Development and Innervation of the Human Inner Ear.

Sensorineural hearing loss can be caused by lesions to the inner ear during development. Understanding the events and signaling pathways that drive inner ear formation is crucial for determining the possible causes of congenital hearing loss. We have analyzed the innervation and expression of SOX2, JAGGED1, β-catenin (CTNNB1), and vitamin D receptor (VDR) in the inner ears of human conceptuses aged 5 to 10 weeks after fertilization (W) using immunohistochemistry.

The "t" time: Investigating handedness through strokes and slopes.

This study investigated the stroke and slope characteristics in left-handed and right-handed handwriting. Stroke (letters t, f, đ, and H) and slope (letters t, f, l, d, and g) directions were analyzed on in-house samples (n = 64), revealing statistically significant differences (p ≤ 0.05) between the groups.

Analysis of clinical parameters as predictors of hearing recovery in patients with sudden sensorineural hearing loss.

Objective: To investigate the impact of certain clinical parameters on likelihood of hearing recovery after SSNHL and to detect potential variables that predict its outcome.

Methods: A retrospective study was conducted in order to identify the clinical parameters which influence hearing recovery after SSNHL. Medical charts of 87 patients diagnosed with SSNHL and treated in the clinic from January 2015 to December 2019 were retrospectively reviewed.
