Aim: To evaluate relationship between frailty and oxidative stress through thiol/disulfide homeostasis parameters [Native thiol (NT), total thiol (TT), and disulfide levels (D), disulfide-native thiol (D/NT), disulfide-total thiol (D/TT), native thiol-total thiol (NT/TT) ratios, and ischemia-modified albumin levels (IMA)].
Materials And Methods: In total, 139 community-dwelling older adults were included. The frailty status, defined by the FRIED frailty index (FFI) and Clinical Frailty Scale (CFS), and comprehensive geriatric assessment results compared with thiol/disulfide homeostasis parameters and ischemia-modified albumin levels.
Results: NT and TT levels were significantly lower in the frail group (respectively; p = 0.014, p = 0.020). The FFI scores were correlated with the levels of NT, TT, D/NT, D/TT, and NT/TT (respectively; r = - 0.25, r = - 0.24, r = 0.17, r = 0.17, r = - 0.17). The significant correlation could not be retained with the CFS scores. In ROC analysis, the AUC for NT was calculated as 0.639 in diagnosing frailty according to the FFI (95% CI 0.542-0.737), AUC was 0.638 for TT (95% CI 0.540-0.735), and AUC was 0.610 for NT/TT (95% CI 0.511-0.780). The AUC was calculated as 0.610 for both D/NT and D/TT in diagnosing physical frailty (95% CI 0.511-0.708).
Conclusion: Thiol/disulfide homeostasis parameters can be a potential biomarker in diagnosing physical frailty. However, further studies are needed for diagnosing frailty defined with cumulative deficit models.

Objective: The aim is to contrast the serum levels of thiol-disulfide homeostasis and ischemic modified albumin between patients with leiomyoma and healthy individuals and to assess the impact of oxidative stress on the etiopathogenesis of leiomyoma.
Methods: In this prospective case-control study, a total of 154 participants were included, consisting of 77 cases diagnosed with leiomyoma and 77 healthy individuals without leiomyoma. The demographic characteristics and ultrasonographic findings of the participants were recorded, and parameters such as albumin, ischemia-modified albumin, and thiol-disulfide homeostasis were evaluated.
Thiol-Disulfide Homeostasis in Noise-Induced Hearing Loss in Rats.

Background: This study was designed to assess if thiol-disulfide homeostasis could be used as diagnostic biomarker in noise-induced hearing loss (NIHL) in a laboratory animal model.
Methods: The study was carried out with a total of 28 female albino rats in 4 groups: group 1 (control group) included rats that were not exposed to noise or any study treatment; in group 2, following noise exposure, rats received 2 mg of dexamethasone per kilogram of body weight via the intramuscular route for 5 days; in Group 3, rats were exposed to noise and received a saline solution for 5 days, in a volume (0.15 cc) matched to that of dexamethasone administered in group 2; and in group 4, rats were exposed to noise, and blood samples were collected during the early phase to assess thiol-disulfide homeostasis without administering any treatment.
Gestational Oxidative Stress and OGTT: Are Pregnant Women's Fears Justified?

Department of Medical Genetics, Aksaray University Faculty of Medicine, Aksaray, Turkey.
Purpose: Pregnancy induces significant metabolic, immunological, and endocrinological changes to support fetal growth. The 75-gram oral glucose tolerance test (OGTT) is standard for gestational diabetes screening, but concerns exist about its potential to induce oxidative stress, affecting both maternal and fetal health. The aim of the study is examining changes in oxidative stress markers and thiol/disulfide homeostasis in pregnant women to evaluate these concerns.

Background/aims: Crohn's disease (CD) is a major subtype of chronic relapsing inflammatory gastrointestinal disorders. In this study, we assessed the possible contributions of serum oxidative/nitrosative stress and dynamic thiol/disulfide homeostasis to CD pathogenesis.
Materials And Methods: Patients with active CD (A-CD) at onset (n = 38), CD patients in the remission (R-CD) (n = 38), and healthy controls (n = 38) were prospectively included in this study.
Dynamic Thiol-Disulfide Homeostasis Post-COVID-19 Depends on Age, Gender, and Symptom Severity.

Introduction: It has been indicated that the thiol-disulfide homeostasis plays a role in the pathogenesis of COVID-19 infection. We assessed the impact on the thiol-disulfide homeostasis at 15-day intervals until 60 days, implicated in the pathogenesis of COVID-19, and its clinical relevance in disease progression.
Methods: In this study, 43 COVID-19 patients (18 females and 25 males) were categorized based on symptom severity, age group, and body mass index.
