Evaluation of SIRT1 Protein Levels and SIRT1/rs7895833 Distributions in Turkish Patients With Obstructive Sleep Apnea.

Objective: Obstructive Sleep Apnea (OSA) is a common heterogeneous sleep disorder that significantly impacts the sleep quality of individuals and leads to severe complications. Patients with OSA often experience disrupted circadian rhythm, hyperactive hypoxia response, and endothelial dysfunction, yet the underlying molecular mechanism remains poorly known. Recent research suggests promising evidence of the potential role of SIRT1 in the etiology of OSA, warranting further investigation.

Assessment of changes in macular structural retinal layers in patients with pathological myopia.

Background/aim: This study aimed to examine changes in the thickness of individual macular retinal layers in eyes with pathological myopia (PM) and to compare the thickness of each retinal layer between the PM and control groups to gain insights into retinal perfusion.

Materials And Methods: The study included 51 eyes in the PM group and 51 eyes in the control group. Optical coherence tomography (OCT) was used to measure the thickness of each retinal layer in the central fovea, parafoveal, and perifoveal regions.

The Impact of Severe COVID-19 on Corneal Endothelial Cells-Analysis of the In Vivo Noncontact Specular Microscopy.

Purpose: This study aimed to investigate the effects of severe COVID-19 infection on the corneal endothelium via in vivo specular microscopy.

Methods: This was an observational, prospective, and controlled study including 56 eyes of 56 severe COVID-19 patients, compared to after-recovery and 56 eyes of 56 age- and gender-matched healthy controls.

Results: Endothelial cell density was lower in the active disease period compared to healthy controls ( = .

Design considerations for photovoltaic energy harvesting in wearable devices.

Wearable technology is emerging as a solution for various bio-mechanic and health-metric applications. Solar photovoltaic energy is a viable supplemental power source that can reduce battery size requirements in wearables. This study outlines the considerations for a wearable sleeve device and its associated power converter system using commercially-available flexible photovoltaic panels located on the forearm.

Standard internal limiting membrane peeling versus internal limiting membrane abrasion technique for primary epiretinal membrane surgery.

Purposes: The purpose of this study is to compare the standard inner limiting membrane peeling technique to the inner limiting membrane abrasion technique with respect to visual outcomes and central retinal thickness in the primary epiretinal membrane surgery.

Methods: A total of 59 eyes from 57 epiretinal membrane patients were separated into two groups including the standard inner limiting membrane peeling group and the inner limiting membrane peeling with abrasion technique group. At 6, 12, and 24 months of follow-up, the mean alteration in best-corrected visual acuity and central retinal thickness were assessed for each group.
