Background: Abnormal thiol/disulphide homoeostasis (TDH) is responsible for the pathogenesis of various diseases. We aimed to examine the TDH in children with steroid-sensitive nephrotic syndrome (SSNS).
Methods: A total of 131 children, 60 with SSNS and 71 healthy controls, participated in the study. Plasma total thiol (TT), native thiol (SH) and disulphide (SS) levels in the SSNS during remission and control groups were estimated using a new method developed by Erel and Neselioglu.
Results: Albumin, TT, SH levels and SH/TT ratio were decreased, whereas SS/SH and SS/TT ratios were elevated in SSNS group compared with control group. However, there was no significant difference in SS levels between the two groups. Albumin level was positively correlated with TT, SH and SS levels in the SSNS group.
Conclusions: We found that TDH shifts in favour of oxidants in children with SSNS in remission. This shift indicates that SSNS patients are exposed to augmented oxidative stress.

Background: Thiol-disulfide homeostasis (TDH) plays a pivotal role in various physiological mechanisms, including antioxidant defence, detoxification, apoptosis, regulation of enzyme activities and cellular signal transduction. TDH can be used as a biomarker to detect oxidative stress (OS) levels and ischemia status in the tissues. Coronary artery bypass grafting (CABG) surgery is a procedure associated with high oxidative stress.

Aim: To investigate changes in nitric oxide (NO) levels, oxidative stress, and dynamic thiol/disulphide homeostasis in the serum and cerebrospinal fluid (CSF) of patients with aneurysmal subarachnoid hemorrhages (aSAH).
Material And Methods: This prospective study included a total of 40 consecutive patients suffering from aSAH, who were operated on within the first 48 hours from onset of symptoms; CSF and blood samples were collected from these patients during their operations. To create a control group, blood samples and cerebrospinal fluid were taken from patients (n=40) without neurologic disorders who had undergone lumbar puncture for spinal anesthesia.
Determination of thiol-disulphide homeostasis in premenstrual syndrome during adolescence.

Division of Adolescent Medicine, Department of Pediatrics, Hacettepe University, Ankara, Türkiye.
Background: Premenstrual syndrome (PMS) characterized by cyclic symptoms during the luteal phase of the menstrual cycle, presents an uncertain etiology in adolescents involving hormonal fluctuations and serotonin-related neurotransmitters with a limited existing literature on the impact of oxidative stress. This study aimed to explore the potential association between PMS and oxidative stress in adolescents.
Methods: In a cross-sectional study conducted at a university hospital, involving 45 adolescent girls aged 12 to 18, participants were categorized based on the presence or absence of PMS using the cut-off point of 110 on the PMS Scale developed by Gençdoğan.

Background: Thiol/disulphide homeostasis (TDH) has a critical role in many cellular activities such as antioxidant protection. Alterations of oxidative stress in the transition period play an important role in development of some diseases and disorders in dairy cows.
Objectives: The purpose of this study is to assess the total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), total thiol, native thiol, disulphide and lipid profile in Simmental and Montofon dairy cows (aged 2-3) before and after calving.

Background: Alzheimer's disease (AD) is a steadily advancing neurodegenerative condition, the occurrence and prevalence of which are on the rise in various populations. Suspected factors contributing to its development encompass the buildup of amyloid β (Aβ) plaques, the formation of neurofibrillary tangles induced by tau proteins, and heightened oxidative stress. In this study, we aimed to evaluate intra-cellular glutathione status and extracellular thiol-disulphide status in patients with AD.
