Objectives: Systemic dehydration may induce osmotic and oxidative stress in the vocal folds, but our knowledge of the biology and mitigation with rehydration is limited. The purpose of this experiment was to evaluate whether systemic dehydration induces vocal fold oxidative and osmotic stress and to compare the impact of rehydration by water intake versus electrolyte intake on osmotic and oxidative stress-related gene expression.

Methods: Four-month-old male Sprague-Dawley rats (N = 32) underwent water restriction.

In the field of bone tissue engineering, biomimetic scaffold utilization is deemed an immensely promising method. The bio-ceramic material Zirconia (ZrO) has garnered significant attention in the biomimetic scaffolds realm due to its remarkable biocompatibility, superior mechanical strength, and exceptional chemical stability. Numerous examinations have been conducted to investigate the properties and functions of biomimetic structures built from zirconia.

Article Synopsis
  • Systemic dehydration decreases blood flow in the superior thyroid artery (STA) of rats, as shown by imaging techniques.
  • After rehydration, blood flow in the STA returns to pre-dehydration levels, indicating that hydration status significantly affects hemodynamics.
  • The study finds no significant changes in the cross-sectional area of the STA due to hydration changes, highlighting the effectiveness of ultrasound and magnetic resonance angiography in observing laryngeal blood vessels.

Objective: Biological data on the beneficial effects of vocal fold rehydration are lacking. This study aimed to examine the effects of acute systemic dehydration on vocal fold gene expression and determine whether rehydration would reverse these changes.

Methods: Male New Zealand White rabbits (N = 24, n = 8/group) provided the animal model.

Rationale: Systemic dehydration negatively alters the expression of vocal fold inflammatory and cell junction markers. These biological changes can have downstream effects on the healing processes of injured vocal folds. In the dermis, reduced hydration prolongs inflammation and delays healing.
