Objective: To determine the serum thiol/disulphide homeostasis in preeclampsia and to investigate the association with clinical parameters.
Methods: Forty-three pregnant women with preeclampsia and 43 healthy, uncomplicated pregnancies were included in the study. Native thiol, disulphide, and total thiol concentrations were measured by a novel automated method.
Results: The serum native and total thiol levels were significantly lower in preeclampsia when compared with the healthy group (p < 0.001). There were significant correlations among the homeostatic parameters and preeclampsia.
Conclusion: Serum thiol/disulphide homeostasis may have a role in the pathogenesis and can be evaluated with the clinical and laboratory findings of preeclampsia.

Background: The study aimed at evaluating the role of thiol-disulphide balance parameters [native thiol (SH), total thiol (SH + SS), disulphide (SS), disulphide/native thiol ratio (% SS/SH), disulphide/total thiol ratio (% SS/Total Thiol) and native thiol/total thiol ratio (%SH/Total Thiol)], which are important oxidative stress markers in the congenital ureteropelvic junction (UPJ) stenosis, in the diagnosis of the disease, and its role in determining the need for surgery and follow-up.
Materials And Methods: This prospective study included 30 children diagnosed with congenital intrinsic ureteropelvic junction obstruction (UPJO) and a control group of 30 healthy children admitted to the pediatric clinic between January 2016 and February 2017. The children with UPJO underwent laparoscopic dismembered pyeloplasty.

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.

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: Mycosis fungoides (MF) is the most common cutaneous T-cell lymphoma with unknown etiopathogenesis. Oxidant and antioxidant balance is important for cell function and normal metabolism. An imbalance between pro-oxidants and antioxidants causes oxidative stress.

This study investigates the impact of orlistat on oxidative stress, spatial memory, recognition memory, and hippocampal tissue in obese rats. The study groups were divided into control, high fat diet-induced obese (HFDIO), HFDIO+orlistat (HFDIO+ORL) groups, each consisting of 8 animals. While control fed with standart diet, HFDIO and HFDIO+ORL fed with high-fat diets for 8 weeks to induce obesity.
