Abstract
(1) Background: Uveal malignant melanoma is the most common adult eye cancer and presents metabolic reprogramming that affects the tumoral microenvironment by altering the redox balance and producing oncometabolites. (2) Methods: The study prospectively evaluated patients undergoing enucleation surgery or stereotactic radiotherapy for uveal melanoma by following systemic oxidative-stress redox markers serum lipid peroxides, total albumin groups and total antioxidant levels (3) Results: Serum antioxidants and lipid peroxides were elevated from pre-treatment to longer-term follow-up. Antioxidants inversely correlated to lipid peroxides: higher in stereotactic radiosurgery patients pre/6/12/18 months post-treatment (p = 0.001-0.049) versus higher lipid peroxides in enucleation surgery patients pre/after/6 months post-treatment (p = 0.004-0.010). An increased variance in serum antioxidants was observed for enucleation surgery patients (p < 0.001), however enucleation did not increase mean serum antioxidants or albumin thiols; only lipid peroxides were increased post-enucleation (p < 0.001) and at 6-month follow-up (p = 0.029). Mean albumin thiols were increased for 18- and 24-month follow-ups (p = 0.017-0.022). Males who had enucleation surgery presented higher variance in serum determinations and overall higher lipid peroxides values pre/post-treatment and at the 18-month follow-up. (4) Conclusions: Initial oxidative stress-inducing events of surgical enucleation or stereotactic radiotherapy for uveal melanoma are followed by a longer-term inflammatory cascade gradually subsiding at later follow-ups.

Abstract
This is the first study to evaluate both the dynamic thiol-disulfide homeostasis and ischemia-modified albumin (IMA) levels in patients with chronic lymphocytic leukemia (CLL). Twenty-nine patients with CLL and 20 controls were included in the study. The dynamic thiol-disulfide balance was determined by the newly developed colorimetric method by Erel. IMA levels were determined by the cobalt binding test. We found that total antioxidant status levels were lower while total oxidant status (TOS) and oxidative stress index (OSI) levels were significantly higher in patients with CLL than controls. Moreover, native and total thiol levels were found to be statistically significant between the study and control groups (p<0.001), whereas no statistically significant difference was noted for IMA levels (p=0.365). A negative correlation was observed between native and total thiol levels, leukocyte, lymphocyte, and TOS. Total bilirubin showed positive correlation with direct bilirubin and alkaline phosphatase. In addition, IMA levels showed a positive correlation with OSI. This study highlights measurement of native and total thiol and IMA levels in patients with CLL for the first time. Dynamic thiol-disulfide homeostasis may contribute in the pathophysiological mechanism, and follow-up to disease in patients with CLL.

Abstract
BackgroundThe aim of the present study was to assess thiol/disulfide homeostasis (TDH) parameters and ischemia-modified albumin (IMA) levels in children with Wilson Disease (WD) and to compare them to healthy controls. Methods: Based on the inclusion and exclusion criteria, fifteen children with WD and twenty-nine healthy children were enrolled, and serum thiol/disulfide and IMA levels were compared between groups. Results: The mean values of native and total thiols were significantly lower in the WD group than in the control group. The mean value of disulfide was significantly higher in the WD group than in the control group. The mean percentages of disulfide/total thiol and native thiol/total thiol were higher in the WD group than in the control group. The IMA value was also higher in the WD group than in the control group. Conclusion: The present study demonstrating altered thiol/disulfide parameters indicates increased oxidative stress in children with WD.

Abstract
Sustained and dysregulated inflammation, concurrent tumor-induced immune suppression, and oxidative stress are profoundly involved in cancer initiation, presentation, and perpetuation. Within this prospective study, we simultaneously analyzed the preoperative indices of systemic inflammatory response and the representative byproducts of oxidative DNA, protein, and lipid damage with the aim of evaluating their clinical relevance among patients diagnosed with testicular germ-cell tumors (GCT). In the analytical cohort (n = 88, median age 34 years), neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and C-reactive protein (CRP) were significantly altered in patients with a higher tumor stage (p < 0.05). Highly suggestive correlations were found between NLR, dNLR, and SII and modified nucleoside 8-OHdG. CRP and albumin-to-globulin ratio (AGR) significantly correlated with thiols group level and maximal tumor dimension (p < 0.05). Based on receiver operating characteristic (ROC) curve analyses, all the evaluated pre-orchiectomy inflammation markers demonstrated strong performance in predicting metastatic disease; optimal cut-off points were determined for each indicator. Although further large-scale studies are warranted, inflammatory and redox indices may both complement the established tumor markers and standard clinicopathological prognostic variables and contribute to enhanced personalized risk-assessment among testicular GCT patients.

Abstract
INTRODUCTION An excessive perioperative inflammatory reaction can lead to more postoperative complications in patients treated for gastrointestinal cancers. It has been suggested that this inflammatory reaction leads to oxidative stress. The most important nonenzymatic antioxidants are serum free thiols. The purpose of this study was to evaluate whether high preoperative serum free thiol levels are associated with short-term clinical outcomes. METHODS Blood samples were drawn before, at the end of, and 1 and 2 days after surgery of a consecutive series of patients with gastrointestinal cancer. Serum free thiols were detected using a colorimetric detection method using Ellman's reagent. Short-term clinical outcomes were defined as 30-day complications (Clavien-Dindo ≥2) and length of hospital stay. Logistic regression was applied to examine the association between serum free thiol levels and short-term patient outcomes. RESULTS Eighty-one patients surgically treated for gastrointestinal cancer were included in the study. Median age was 68 (range 26-87) years, and 28% were female. Patients in the lowest tertile of preoperative serum free thiols had a threefold higher risk to develop postoperative complications (odds ratio [OR]: 3.4; 95% confidence interval [CI]:1.1-10.7) and a fourfold higher risk to have an increased length of stay in the hospital (OR 4.0; 95% CI 1.3-12.9) compared with patients in the highest tertile. CONCLUSIONS Patients with lower preoperative serum free thiol levels, indicating a decrease in extracellular antioxidant capacity and therefore an increase in systemic oxidative stress, are more likely to develop postoperative complications and show a longer in hospital stay than patients with higher serum free thiol levels.

Abstract
BACKGROUND/AIM The aim of this study was to evaluate the effects of general anaesthesia and ultrasonography-guided interscalene block on pain and oxidative stress evaluated by thiol-disulphide balance and C-reactive protein levels in patients undergoing shoulder arthroscopy. MATERIALS AND METHODS A total of 42 patients aged 18-75 years who were scheduled to undergo shoulder arthroscopy were randomised into interscalene block group (Group-IB, n = 20) and general anaesthesia group (Group-GA, n = 22). All patients received patient-controlled analgesia during the postoperative period. Additional analgesics were administered to patients with a visual analogue scale score of >4. Native-thiol, total-thiol, disulphide and C-reactive protein levels were measured. Patients' visual analogue scale scores, morphine and additional analgesic consumption were recorded. A shift in thiol-disulphide balance towards decreased thiol and increased disulphide levels was regarded as an indicator of oxidative stress. RESULTS Pain level, morphine and additional analgesic consumption were higher in Group-GA. Native-thiol and total-thiol levels were higher in Group-IB postoperatively and also disulphide levels were lower at postoperative 18 hours. C-reactive protein levels were similar in both the groups. CONCLUSION Interscalene block induced less oxidative stress during the postoperative period, as evaluated by thiol-disulphide balance. In shoulder arthroscopy, interscalene block provides more stable haemodynamics perioperatively and facilitates better postoperative pain control.

Abstract
BACKGROUND Oxidative stress status in different cancer types was investigated before, but not studied in gastric intestinal metaplasia to the best of our knowledge. Purpose of this study is to examine whether there is a difference between oxidative stress status in patients with intestinal metaplasia (IM) compared to individuals without IM, we compared the serum levels of disulfide (SS), total thiol (TT) and native thiol (NT). METHODS This was a prospective, non-randomized casecontrol study including 67 patients with histopathologically confirmed IM and 60 individuals demographically matched in terms of age, gender, BMI, smoking status, and chronic diseases as control group. RESULTS The mean NT, TT and NT to TT (NT/TT) ratios were statistically significantly higher in IM group compared to controls ((351.71 ± 81.9 mol/L vs. 271.82 ± 54.13 mol/L, p=0.000), (391.5 ± 92.69 mol/L vs. 308.59 ± 55.53 mol/L, p=0.000) and (0.89 ± 0.6 vs. 0.87 ± 0.29, p=0.022), respectively). The mean SS to TT (SS/TT) ratio was significantly lower in IM group than control group (0.050 ± 0.31 vs. 0.060 ± 0.014, P=0.022). Median SS and mean SS/NT ratio was similar in both groups (16.3 (3.3-78) vs. 18.3 (10-32.7), p=0.271 and 0.055 ± 0.041 vs. 0.070 ± 0.019, p=0.068, respectively). In ROC analysis, cut off value of SS/NT for IM was found 0.062, in regression analysis, SS/NT <0.062 was found as an independently prognostic marker for IM (OR, 2.38; 95%CI: 1.168-4.865, P=0.017). CONCLUSIONS SS/NT ratio lower than 0.062 was found as an independently prognostic marker for IM. This ratio could help to distinguish which patients should be followed closely for gastric cancer.

Abstract
To assess the distinctiveness of serum native thiol (NT), total thiol (TT) and disulfide (SS) levels in PCa patients, we created a new parameter, prostate thiol index (PTI) [tPSA (TTxPVxAge) -1/2 ]. We determined the performance of the PTI on PCa diagnosis. A total of 107 male patients (PCa:65; BPH:42) who were separated according to their Gleason scores, ISUP grades and EAU risk groups and 20 healthy subjects were included. The performances of the tests were determined. The PCa and BPH groups had lower NT and TT levels and higher SS levels than the control group. PCa patients had higher PTI, tPSA, fPSA, PSAD levels, lower fPSA%, PV and PSA-AV levels than BPH patients. TT, PTI, tPSA, fPSA, fPSA%, PSA-AV, PSAD and PV had significant diagnostic performances. PTI had the highest AUC value and accuracy, PSA-AV had the highest specificity, and fPSA had the lowest sensitivity. The performance of the PTI was the best in distinguishing PCa from BPH. PTI, tPSA and PSAD positively and PSA-AV negatively correlated with ISUP grades and EAU groups. TT can contribute to the discrimination of PCa from BPH and PTI may decrease unnecessary biopsies in clinical practice.

Abstract
BACKGROUND Multiple sclerosis (MS) is a neuroinflammatory disease and inflammation and oxidative stress play important roles in its pathology. Thiol/disulphide homeostasis (TDH) is a special oxidative stress biomarker that has been found to be affected in several disorders including MS. There is no study demonstrating the effects of attack status of the relapsing-remitting multiple sclerosis (RRMS) patients on TDH levels. Our aim was to determine TDH levels in three different periods of RRMS patients and healthy individuals. METHODS The study was carried out in 29 patients with RRMS without a prior attack in the last twelve months (MS Control), 21 RRMS patients having a clinical acute attack within the last week (MS relapse), 12 of 21 MS relapse patients one month after the onset of attack and following 1000 mg methylprednisolone for 7 days (MS Remission) and 30 age- and sex-matched healthy individuals. TDH status was determined using an automated spectrophotometric analysis method. TDH levels in all patient groups and control subjects were compared with each other. RESULTS The lowest native thiol, total thiol levels and native thiol/total thiol ratio were found in the MS relapse patients in comparison to the MS control, MS remission groups and healthy controls. In contrast, disulphide levels, disulphide/native thiol and disulphide/total thiol ratios were highest in the MS relapse group compared to the other patient groups and healthy subjects. CONCLUSION Our findings indicate that increased oxidative stress in RRMS patients is reflected with decreased native and total thiol and increased disulphide levels. Since the formation of disulphide bonds is reversible, the progression of RRMS involving abnormal TDH may be controlled, converting disulphides to thiols. So, we suggest determining the dynamic TDH status as a novel and special biomarker in the diagnosis and prognosis of the RRMS patients.

In vivo assessment of dichlorvos induced histological and biochemical impairments coupled with expression of p53 responsive apoptotic genes in the liver and kidney of fish, Channa punctatus (Bloch, 1793). Comp Biochem Physiol C Toxicol Pharmacol 2021; 245:109032. [PMID: 33722766 DOI: 10.1016/j.cbpc.2021.109032] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 03/07/2021] [Accepted: 03/11/2021] [Indexed: 12/26/2022]
Abstract
Sub-lethal exposure of dichlorvos induces oxidative stress, consequent genetic instability and apoptosis coupled with impairments in biochemical, histopathological and transcription of genes in Channa punctatus. Exposure of 5% (0.041 mg/L; E2) and 10% (0.082 mg/L; E3) of 96 h-LC50 of dichlorvos significantly (p < 0.05) elevated the reactive oxygen species (ROS) generation and activities of SOD and CAT, as compared to control (E1) after 30 d. The maximum reduction in reduced glutathione (GSH) was recorded in the liver (18.53 ± 0.81 μg/mg of protein) and kidney (19.32 ± 0.97 μg/mg of protein); while the total protein contents were also found reduced, 278.38 ± 8.40 μg/mL (liver) and 248.44 ± 7.28 μg/mL (kidney), after 30 days in E3, in comparison to respective controls. Further, significant (p < 0.05) induction in micronuclei (MN) and apoptotic cells (AC), in a dose- and exposure-based manner were also recorded. Moreover, a significant (p < 0.05) up-regulation of p53 (2.51-fold in liver), bax (2.03-fold in liver; 1.99-fold in kidney) and casp3a (2.26-fold in liver; 2.10-fold in kidney) together with an elevated expression of cat (1.73-fold in liver; 1.12-fold in kidney), p53 (1.27-fold in kidney) and apaf-1 (1.72-fold in liver) in fish exposed to higher dose of dichlorvos for 30 d evidently reflects geno-toxicological potential of referenced pesticide. Disturbed biochemical and molecular parameters evince that the fish experienced oxidative stress as is further supported by prominent pathological observations in liver and kidney. Findings are, thus, helpful in organ-specific molecular scanning against aquatic toxicants like dichlorvos.

Abstract
OBJECTIVES Restless legs syndrome (RLS) is a common neurological condition. Oxidative stress plays an important role in its pathogenesis. Thiol-disulphide homeostasis (TDH) is a new biomarker of oxidative stress. We studied plasma TDH to determine whether TDH could be used as a new biomarker for RLS and evaluated correlations between TDH and various disease severity rating scales. METHODS A total of 25 RLS patients and 25 healthy controls were included into the study. TDH status was determined using an automated spectrophotometric analysis method and correlations were analyzed between the TDH status and various disease rating scales in the RLS patients. RESULTS Plasma total (401±27 μmol/L) and native thiol (354±30 μmol/L) levels were significantly lower, but disulphide level (24±6 μmol/L) was significantly (<0.0001) higher in the RLS patients compared to the controls (455±36, 424±37, 15±5 μmol/L, respectively). The disulphide/native thiol and disulphide/total thiol ratios increased, in contrast, native thiol/total thiol ratio decreased significantly in the RLS patients compared to the healthy controls (<0.0001). The disulphide levels correlated positively with age and various rating scores of the RLS patients. International Restless Legs Syndrome Study Group (IRLSSG) rating score and age correlated negatively with the total and native thiol levels. CONCLUSIONS Our findings indicate increased oxidative stress in the RLS patients reflected by decreased native and total thiol, and increased disulphide levels and positive correlations between the disulphide levels and various rating scores. We suggest dynamic TDH status to be used as a novel biomarker for the diagnosis and follow-up of the RLS patients.

Abstract
BACKGROUND In this study, we assessed thiol/disulfide homeostasis (TDH) parameters and ischemia-modified albumin (IMA) levels in children with irritable bowel syndrome (IBS) compared with healthy children. METHODS Fifty-six children with IBS and 53 healthy children were included in the study after assessment of inclusion and exclusion criteria. Plasma thiol/disulfide and IMA levels were compared between children with and without IBS. RESULTS The mean values of native thiol, total thiol, and disulfide were 343.779 ± 138.654 μmol/L, 365.398 ± 140.148 μmol/L, and 23.190 ± 4.978 μmol/L, respectively, in the IBS group and 409.908 ± 69.288 μmol/L, 433.481 ± 76.891 μmol/L, and 20.090 ± 4.252 μmol/L, respectively, in the control group. Native thiol and total thiol values were significantly reduced in the IBS group compared with the control group. The mean IMA values were 0.835 ± 0.083 (g/L) and 0.778 ± 0.072 in the IBS and control groups, respectively. The IMA value was significantly increased in the IBS group. CONCLUSION Impaired thiol/disulfide homeostasis and increased IMA levels can be considered etiological factors in children with IBS.

Abstract
INTRODUCTION We aimed to evaluate plasma thiol and disulphide levels as an additional marker to prostate specific antigen (PSA) in the diagnosis of prostate cancer (PCa). METHODS Between March 2017 and January 2018 prospective study was conducted among patients with PSA levels of 2.5-20 ng/mL without suspicion of malignancy in rectal examination and who underwent prostate needle biopsy. Patients were divided into two groups according to PSA level as 2.5-10 ng/mL (Group 1) and 10.01-20 ng/mL (Group 2). Diagnostic efficacy of thiol, disulphide and PSA levels were measured by ROC analysis. RESULTS A total of 76 patients were included in the study. There were 49 patients in group 1 and 27 patients in group 2. There was no significant difference between two groups in terms of PSA density and prostate size. In Group 1, area under curve (AUC) was higher in PSA than other parameters with statistically significant difference (p<.05). In group 2, AUC of native and total thiol was higher than PSA but there was no statistically significant difference for AUC in parameters. CONCLUSIONS We think that plasma thiol test may be used in diagnosis of prostate cancer while PSA levels between 10 to 20 ng/mL. However, further studies are required.

Abstract
Serum Total Thiol (TT), Native Thiol (NT), and Disulfide (SS) levels were found significantly lower in benign proliferative pathologies and cancer disease compared to healthy subjects. We conducted this prospective study to investigate the possible predictive and prognostic significance of these markers in non-small cell lung cancer (NSCLC), which is one of the most associated cancers with oxidative stress. This was a non-randomized, prospective, and case-control study of 120 subjects, including 60 patients with metastatic or inoperable NSCLC at the time of diagnosis and 60 demographically-matched controls. Morning fasting venous blood serum samples from both NSCLC and control group were stored at -80 °C for equal periods and then TT, NT, and SS levels were measured spectrophotometrically. Serum TT, NT, and SS levels were compared between groups and their relationships with demographic features and survival of NSCLC patients were analyzed. In results, Serum TT, NT, and SS levels were significantly lower in NSCLC patients than those in control group, with a low SS level being an independent indicator of poor survival.

Abstract
PURPOSE Lowered thiol (-SH) groups and glutathione (GSH) metabolism may be associated with prostate cancer (PCa) and benign prostatic hyperplasia (BPH). The objectives of this study were to systematically review and meta-analyze the associations among -SH groups, GSH, GSH peroxidase (GPx), GSH reductase (GR), and GSH transferase (GST) and PCa/BPH. METHODS Four electronic databases were searched for studies that reported -SH and GSH variables in PCa/BPH and healthy controls (HC) and the data were meta-analyzed by calculating Hedges's g with 95% confidence intervals. RESULTS Twenty studies were included in this meta-analysis. Total -SH (g = -1.750, -2.341/-1.159), GPx (g = -0.789, -1.234/-0.344), GSH (g = -2.219, -4.132/-0.305), and the combination of -SH, GPx, and GSH (g = -1.271, -1.271/-0.800) were significantly lower in PCa patients than in HC. -SH (g = -1.752, -3.123/-0.381) and the combination of -SH, GPx, and GSH (g = -0.813, -1.298/-0.327) were significantly lower in BPH patients than in HC. GPx was significantly lower in PCa than in BPH patients (g = -0.455, -0.896/-0.014). Heterogeneity levels were very high, but Egger's test showed that none of the biomarkers showed significant publication bias. CONCLUSION Thiol/GPx antioxidant defenses are significantly attenuated in patients with PCa while patients with BPH occupy an intermediate risk group position between PCa patients and HC.

Abstract
Dynamic thiol-disulfide homeostasis (TDH) is a new area has begun to attract more scrutiny. Dynamic TDH is reversal of thiol oxidation in proteins and represents the status of thiols (-SH) and disulfides (-S-S-). Organic compounds containing the sulfhydryl group is called thiol, composed of sulfur and hydrogen atoms. Disulfides are the most important class of dynamic, redox responsive covalent bonds build in between two thiol groups. For many years, thiol levels were analyzed by several methods. During last years, measurements of disulfide levels have been analyzed by a novel automated method, developed by Erel and Neselioglu. In this method, addition to thiol (termed as native thiol) levels, disulfide levels were also measured and sum of native thiol and disulfide levels were termed as total thiol. Therefore, TDH was begun to be understood in organism. In healthy humans, TDH is maintained within a certain range. Dysregulated dynamic TDH has been implicated several disorders with unknown etiology. A growing body of evidence has demonstrated that the thiol-disulfide homeostasis is involved in variety diseases, such as diabetes mellitus, hypertension, nonsmall cell lung cancer, familial Mediterranean fever (FMF), inflammatory bowel diseases, occupational diseases, gestational diabetes mellitus and preeclampsia. These results may elucidate some pathogenic mechanism or may be a predictor indicating diagnostic clue, prognostic marker or therapeutic sign. In conclusion, protection of the thiol-disulfide homeostasis is of great importance for the human being. Evidence achieved so far has proposed that thiol-disulfide homeostasis is an important issue needs to elucidate wholly.

Abstract
AIM The evaluation of dynamic thiol-disulfide homeostasis among patients with the cancer of the uterine cervix. METHODS The study was conducted in 62 cervical cancer patients and 61 healthy women who had been followed up in an obstetrics and gynecology clinic between September 2018 and April 2020. Serum disulfide, native thiol, total thiol, ischemia modified-albumin, total antioxidant and oxidant capacities, and oxidative stress index values were measured in all participants. RESULTS The mean plasma disulfide levels of the cervical cancer group was statistically significantly higher than that of the control group (25.79 ± 6.90 μmol/L, 22.31 ± 6.11 μmol/L, respectively) (P = 0.004). Plasma native thiol and total thiol levels were lower in cervical cancer patients (299.27 ± 99.05 μmol/L and 350.86 ± 102.72 μmol/L, respectively) compared to controls, but no statistically significant difference was observed (318.00 ± 93.75 μmol/L and 376.44 ± 98.51 μmol/L, respectively) (P = 0.284, P = 0.161). With respect to the ischemia modified-albumin level, no statistically significant difference was observed between two groups. There were statistically significant positive association between disulfide level and both the stage of cervical cancer (r = 0.278, P = 0.029) and total oxidant capacity level (r = 0.256, P = 0.046). CONCLUSION Dynamic thiol-disulfide homeostasis may participate in the pathophysiological mechanisms of cervical cancer and may be a potential biomarker for early identification of cervical cancer in future.

Abstract
PURPOSE To evaluate the ability of thiol-disulphide homeostasis to predict renal injury in ureteral obstruction by matching renal scintigraphy and pathological findings in an experimental rat model. METHODS 24 rats were randomized and divided into 3 groups as sham, partial and complete. Blood samples for biochemical evaluations and dimercaptosuccinic acid (DMSA) renal scintigraphy were performed at the beginning and on the 7th day postoperatively. Only a midline abdominal incision was done in sham group. Left ureter of partial group was dissected and gently buried into the psoas muscle. In complete group, left ureter was dissected and ligated. RESULTS Statistically significant association was found between left kidney function loss percentage, native thiol, total thiol and creatinine alterations and pathological EGTI (Endothelial, Glomerular, Tubular, Interstitial) scores (r = - 0.867, r = - 0.815, r = 0.745, r = - 0.911; p = 0.000). Statistically significant difference was detected between groups in terms of postoperative native thiol and total thiol values (p = 0.000, p = 0.001). There was also a significant difference in preoperative and postoperative comparisons of these parameters in partial and complete obstruction groups (p = 0.012, p = 0.018). There was a significant difference in terms of postoperative disulphide/native thiol and native thiol/total thiol ratios in complete obstruction group compared to other groups (p1 = 0.011, p2 = 0.040; p1 = 0.015, p2 = 0.028). CONCLUSIONS Association with scintigraphic and pathological results empowers the value of this parameter. Disulphide/native thiol and native thiol/total thiol ratios indicate complete obstruction. These findings may shed light to more comprehensive studies.

Abstract
INTRODUCTION Thiol and disulphide levels are biomarkers that provide useful information about oxidative stress and antioxidant capacity, showing a different homoeostasis in inflammatory and proliferative diseases. We aimed to clarify the possible aetiology of this disease by using thiol and disulphide levels in patients with fibromyalgia, the basis of which has not yet been clearly elucidated. MATERIAL AND METHODS A total of 156 individuals: 86 patients with fibromyalgia and 70 age-matched controls were included in this prospective non-randomised case-control study. Demographic characteristics including smoking status, body mass index (BMI), the duration of complaints, and pain levels were carefully recorded. Dynamic thiol-disulphide homoeostasis in blood samples was determined by an automatic-spectrophotometric method. The Mann-Whitney U and Student's t-test were used to determine the differences between the groups. RESULTS Sex, BMI, and smoking status were similar between the groups (p = 0.62, p = 0.09, and p = 0.64, respectively). While native thiol levels were found to be high in patients with fibromyalgia (p = 0.018), disulphide levels and the rates of disulphide/native thiol and disulphide/total thiol were significantly low (p = 0.049, p = 0.007, and p = 0.007, respectively). Correlation analysis showed no significant relationship between thiol-disulphide levels and duration of complaints or pain level. CONCLUSIONS Thiol-disulphide balance in fibromyalgia was found to be similar to benign proliferative diseases, suggesting that the underlying mechanism is more likely to be of proliferative pattern rather than inflammatory. Additionally, fibromyalgia is not directly associated with increase in oxidative stress. The molecular mechanisms need to be elucidated.

Abstract
BACKGROUND In addition to the genetic complexity of hypertrophic cardiomyopathy (HCM), there must be other disease-modifying factors that contribute to its highly variable clinical and phenotypic expression. The authors aimed to investigate serum thiol/disulphide homeostasis as a proxy for oxidative stress using a novel automated assay in patients with HCM. METHODS This cross-sectional study was conducted on 119 patients with HCM and 52 without HCM. The methods used to measure dynamic thiol/disulphide homeostasis as calorimetric and duplex quantities were developed in 2014. RESULTS Median serum native thiol levels were significantly lower in patients with HCM than in those without (312.5 μmol/L [285-370 μmol/L] vs 421 μmol/L [349-469.5 μmol/L]; p < 0.001). Serum total thiol levels and disulphide levels were considerably lower than those in the control group ([844.68 ± 195.99 μmol/L vs 1158.92 ± 243.97 μmol/L; p < 0.001], [259.13 ± 65.66 μmol/L vs 375.02 ± 79.99 μmol/L; p < 0.001], respectively). Serum disulphide/native thiol ratios and disulphide/total thiol ratios were significantly lower in HCM patients than in controls (0.80 ± 0.09 vs 0.92 ± 0.05; p < 0.001 and 0.31 [0.30-0.32] vs 0.32 [0.32-0.33]; p < 0.001). Finally, reduced thiol ratios were higher and oxidized thiol ratios were significantly lower in patients with HCM than in controls. CONCLUSIONS Despite the fact that antioxidant capacity was impaired, the extracellular environment remained in a reducing state by keeping serum disulphide/native thiol ratios low. Therefore, the authors speculate that HCM may behave similarly to tumours with respect to serum thiol-disulphide levels.

Abstract
We studied dynamic thiol/disulphide homeostasis, an indicator of oxidative stress, to investigate the effects of newly initiated exercise training on sedentary obese adults. Seventeen sedentary obese adults and 15 normal-weight controls were included in the sample for this study. The obese adults were given a physical exercise training program that lasted twelve weeks. Before and after the exercise training program, blood samples were collected, and serum thiol/disulphide parameters were measured by using a novel technique. Before the start of the exercise training, it was observed that thiol/disulphide homeostasis was impaired, and this impairment was positively correlated with body mass index in sedentary obese adults because of the higher reactive oxygen species production in adipose tissue. However, while the obese participants' body mass index significantly decreased, the thiol/disulphide homeostasis parameters in the obese adults did not change over time as calculated at the baseline and compared to the calculation after the twelve weeks of exercise training. Despite a decrease in body mass index that occurred after the twelve weeks of exercise training, there was a lack of improvement in the obesity-induced impairment of thiol/disulphide homeostasis, which suggests that a newly initiated exercise training program may lead to oxidative stress.

Abstract
Background This study aimed to show the status of thioldisulphide homeostasis in essential thrombocytosis patients, which is known to play a role in platelet function. Methods The study included 27 ET patients and a control group of 36 healthy subjects. Serum total (-SH + -S-S-) and native (-SH) thiol levels were measured in all subjects using an automatic method. Results Age and gender distribution were similar in both groups. Compared with the control group, in the ET group, there were increased native thiol and total thiol levels (p = 0.001, p = 0.046). There was no correlation between thiol, total thiol and disulphide ratios with Jak2 mutation, hemorrhage and thrombosis. A positive correlation was determined between thrombosis and thiol disulphide homeostasis (p = 0.058). The study results showed that thiol-disulphide homeostasis shifted to the proliferative side in ET, in which ineffective erythropoiesis was predominant. It is also known that platelets are more active in ET cases and thiol disulphide balance is important in platelet function. Conclusions This result suggests that thrombotic complications may be reduced if the formation is achieved of mechanisms (oxidation mechanisms) that will trigger the increase of disulphide groups. However, more extensive research is needed on this subject.

Abstract
Purpose A dynamic thiol/disulfide balance is pivotal in organizing anti-oxidant defense, detoxification, apoptosis, and enzyme activities, as well as transcription and cellular signal-transfer mechanisms. The connection between urolithiasis and oxidant/antioxidant status, which can be assessed through thiol-disulfide homeostasis (TDH), has not yet been examined. In this study, we evaluated the effects of TDH on the formation, size, and location of stones by examining the associations between TDH parameters and urolithiasis. Materials and Methods Patients with urolithiasis and healthy controls were recruited. The patients were divided into subgroups in terms of stone size (>15 mm or ≤15 mm) and stone location (nephrolithiasis or ureterolithiasis). TDH parameters were measured using a novel automatic and spectrophotometric method and compared statistically. Results TDH parameters were different between the urolithiasis and control groups. TDH tended towards the disulfide side in the urolithiasis group. Stone size increased an average 0.14 mm with a 1 µmol/L increase in disulfide level and decreased an average 0.058 mm with a 1 µmol/L increase in native thiol level. Disulfide and native thiol levels were found to be different across patients with stone size >15 mm, ≤15 mm, and controls (p<0.001 and p<0.001, respectively). However, the nephrolithiasis and ureterolithiasis groups were similar in respect of TDH parameters. Conclusions In this study, it was found that patients with urolithiasis displayed oxidative stress characterized by a TDH tendency towards the disulfide side, and an inadequate antioxidant response identified by a lower level of native thiol as compared with healthy controls.

Abstract
BACKGROUND Our study investigates whether Native Thiol, Total Thiol and disulphide levels measured in serum of patients with prostate cancer and prostatitis and of healthy subjects, have any role in differential diagnosis. MATERIALS AND METHODS Patients followed up for histopathologically verified diagnosis of prostate cancer and prostatitis in 2016-2017 at the Medicalpark Gaziantep Hospital Urology Clinic were included in the study. Native Thiol (NT), Total Thiol (TT), Dynamic Disulphide (DD) levels in serum were measured by a novel automated method. RESULTS NT, TT, DD, NT / TT ratios, DD / TT ratio and DD / NT ratio were measured as 118.4 ± 36.8μmoL / L, 150.3 ± 45.3μmoL / L, 15.9 ± 7μmoL / L, 78.8 ± 7μmoL / L, 10.5 ± 3.5μmoL / L, 13.8 ± 5.8μmoL / L respectively in patients with prostate cancer; as 116.4 ± 40.5μmoL / L, 147.5 ± 50.1μmoL / L, 15.5 ± 8.7μmoL / L, 79.7 ± 9μmoL / L, 10.1 ± 4.5μmoL / L, 13.5 ± 7.2μmoL / L in patients with prostatitis and as 144.1 ± 21.2μmoL / L, 191 ± 32.3μmoL / L, 23.4 ± 10.1μmoL / L, 76.1 ± 98.3μmoL / L, 11.9 ± 4.1μmoL / L, 16.4 ± 6.9μmoL / L in healthy subjects. Significant difference was detected between groups of NT, TT and DD levels (p = 0.008, p = 0.001, p = 0.002). No significant difference was detected in terms of the NT / TT, DD / TT and DD / NT rates (p = 0.222, p = 0.222, p = 0.222). CONCLUSIONS Serum NT, TT, DD levels in patients with prostatitis and prostate cancer were found significantly lower compared to the control group. This indicates that just as inflammation, prostate cancer also increases oxidative stress on tissues.

Abstract
Objective: We aimed to investigate the oxidative stress status in children with β-thalassemia major (β-TM) by measuring native thiol (SH), disulfide (SS) and total thiol (SH + SS) plasma levels. Methods: This study was carried out from November 2017 to March 2018 at the Pediatric Hematology Clinic of the Harran University Medical Faculty Hospital. Blood specimens were collected from 100 participants, including 50 β-TM patients and 50 controls, and SH, SS and SH+SS levels were detected through a newly developed method. Results: SH, SS, SH+SS levels and SS/SH ratio were markedly higher in β-TM patients than in controls. In β-TM group, SH and SH+SS levels were positively correlated with age, albumin and total bilirubin. Serum ferritin level was positively correlated with SH, SH+SS, aspartate transaminase and alanine transaminase. Conclusions: We found that the SS/SH ratio was high in patients with β-TM, which shows increased oxidative stress. This ratio may be considered as a tool for the determination of oxidative status in such patients due to easily calculate, suitable for routine use and economical.

Abstract
Objective: Extracorporeal Shockwave Lithotripsy (ESWL) is a non-invasive method that is effective at crushing stones in the upper urinary tract. Disturbance of the thiol/disulfide homeostasis, in favor of the disulfide, has been shown to be involved in the disease pathogenesis. Methods: A total of 36 individuals that underwent ESWL had blood samples collected before ESWL (0hrs), 6hrs, and one week after the ESWL. Sera native and total as wells as disulfide amount was measured using an automated method sodium borohydrate (NaBH4) reduction. In addition, Ischemia Modified Albumin (IMA) levels were measured using colorimetric assay method. Results: Native thiol level was reduced at the 6th hour following ESWL compared to baseline. While the ratios of disulfide level, Disulfide/Total Thiol (DTT), Disulfide/Native Thiol (DNT) and IMA level were increased at the 6th hour following ESWL compared to baseline, they were found to be similar with their baseline values at the end of 1st week. Total thiol and native /total thiol did not show any significant change. Conclusions: ESWL treatment disrupts thiol/disulfide homeostasis and the structure of albumin at the acute term. Therefore, it increases protein oxidation and leads to increased oxidative stress. However, this state is transient and returns to normal within the proceeding days.

Is oxidative stress measured by thiol/disulphide homeostasis status associated with prostate adenocarcinoma? Cent Eur J Immunol 2018; 43:174-179. [PMID: 30135630 PMCID: PMC6102614 DOI: 10.5114/ceji.2017.72285] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2017] [Accepted: 07/28/2017] [Indexed: 01/09/2023] Open
Abstract
Aim of the study We aim to examine the relation between thiol/disulphide homeostasis and transrectal ultrasound guided prostate biopsy (TRUS-Bx) results and evaluate whether it was effective on the distinction of benign and malign prostate disease. Material and methods The study included 29 men histopathologically diagnosed as prostate adenocancer (Pca) (group 1), 30 men having benign prostate hyperplasia (BPH) (group 2) and age match 30 healthy individuals in the control group (group 3). Thiol/disulphide homeostasis was measured using a novel automatic and spectrophotometric method. Results Among the three groups, a statistically significant difference was detected among native thiol, total thiol levels and disulphide/total thiol, disulphide/native thiol and native thiol/total thiol ratios which are thiol/disulphide homeostasis parameters apart from disulphide (p < 0.001, p < 0.001, p < 0.001, p < 0.001, p < 0.001 respectively). Additionally, no significant difference was detected in albumin and total protein levels among the groups (p = 0.223, p = 0.316 respectively). Serum native and total thiol levels were high and disulphide level was low in group 1 when compared to the group 2 (p = 0.003, p = 0.007, p = 0.265 respectively). In addition, serum native thiol, total thiol and disulphide levels were low in group 1 when compared to the group 3, but while low native and total thiol levels were significant, low disulphide levels were not found significant (p < 0.001, p < 0.001, p = 0.331, respectively). Conclusions Thiol/disulphide homeostasis was found to be disturbed in Pca patients detected with TRUS-Bx. This is suggesting serum native thiol, total thiol level and ratios provides a novel biomarker for the role for oxidative stress in disease etiopathogenesis.

Abstract
BACKGROUND The aim of this study is to measure and compare the dynamic thiol and disulphide homeostasis between patients with Uterine Myoma (UM) and healthy subjects. MATERIAL AND METHOD A total of 54 patients with UM who were diagnosed by transvaginal ultrasonography and 37 age- and body mass index-matched healthy individuals were included in this study. Thiol/disulphide homeostasis was measured by a novel automatic spectrophotometric method. RESULTS The mean serum native thiol, disulphide, and thiol levels were statistically lower in UM group than those in the control group [(284.66±59.41μmol/L vs. 320.98±56.17μmol/L, P<0.0001), (17.27±5.59μmol/L vs. 22.38±6.93μmol/L, P<0.0001) and (319.21±61.69 vs. 365.76±61.46μmol/L, P<0.0001), respectively]. There were no statistically significant differences in ratios of the disulphide/native thiol, native thiol/total thiol, and disulphide/total thiol among patients with UM versus healthy control group (P=0.096, 0.092, 0.092, respectively). CONCLUSION It was found that the native thiol, total thiol, and disulphide levels in patients with UM decreased while the ratio of native thiol/disulphide remained unchanged.It is necessary to investigate whether these findings have a role in the etiology and clinical course of the UM.
