ABSTRACT

PURPOSE: Oxidative stress in the vertebral endplates of patients with low back pain and Modic changes (MCs) (types I, II, and III) endplate changes on magnetic resonance imaging. 8-iso-prostaglandin F2α (8-iso-PGF2α) has been proposed as new indicator of oxidative stress. Raftlin, as an inflammatory biomarker, has been previously reported in inflammatory diseases. Oxidative stress plays an important role in various human diseases. This study was aimed to assess Raftlin and 8-iso-PGF2α levels in patients with MCs. METHODS: Patients with MCI, II, and III (n = 45) and age- and sex matched controls subjects (n = 45) were enrolled in this study. 8-iso-PGF2α and Raftlin levels in the serum samples of both groups were measured with enzyme-linked immunosorbent assay. RESULTS: In our study results, raftlin levels changed in parallel with prostaglandin levels (p < 0.05). Raftlin levels changed in parallel with prostaglandin levels (p < 0.05). The levels of 8-iso-PGF2α and Raftlin levels showed increase in patients with MCs and the control group (p < 0.05). In addition, a significant positive correlation was found between MC-I, MC-II, MC-III and Raftlin (r = 0.756, 0.733, 0.701 p < 0.001, respectively). A significant positive correlation was found between ISO (Respectively; r = 0.782, 0.712, 0.716 p < 0.001). In our evaluation between Raftlin and Iso, a significant positive relationship was determined. (r = 0.731, p < 0.001). CONCLUSION: Our findings indicated that oxidative stress in patients with MC-I may be aggravated and it may cause an inflammation formation of the lesion areas in these patients. Also, the increased 8-iso-PGF2α and Raftlin levels in patients with MC-II and MC-III may be an adaptive response to against oxidative stress.

ABSTRACT

BACKGROUND: Raftlin is a large, major lipid raft protein of cell membranes. Raftlin levels have not been previously examined in patients with obstructive sleep apnea (OSA). Our study aimed to evaluate the changes in raftlin, interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor alpha (TNFα) values from the preoperative state to the third month postoperatively in patients undergoing expansion sphincter pharyngoplasty for OSA. METHODS: Of 60 patients, 10 patients had mild OSA (AHI 5-14), 10 moderate (AHI 15-29), 10 severe (AHI ≥ 30), and 30 with AHI < 5 formed a control group. Preoperatively and at 3 months post-operatively, IL-6, IL-8, TNFα, and raftlin values were measured. RESULTS: Preoperatively, mean raftlin levels were 914.4 ± 62.7 pg/mL for controls, 910.0 ± 42.5 pg/mL in mild, 1000.5 ± 63.3 pg/mL in moderate, and 1386.3 ± 101.4 pg/mL in severe groups, with moderate and severe groups significantly elevated compared to controls (p < 0.001). Preoperatively to 3 months post-operatively, raftlin levels decreased significantly in each OSA group (p < 0.05). Levels of IL-6, IL-8 and TNFα followed similar patterns at baseline and after surgical intervention. CONCLUSIONS: Raftlin levels at the third postoperative month decreased significantly compared with preoperative levels in parallel with other markers of inflammation.

ABSTRACT

Reactive oxygen species (ROS) are crucial in all wound-healing processes. Raftlin also plays an important role in the induction of the autoimmune response and the vascular inflammatory response. Inflammatory mediators induce continuous synthesis and secretion. To the best of our knowledge, although there are studies in the literature on antioxidant enzyme levels (superoxide dismutase [SOD], catalase [CAT]) and oxidative stress markers, there are no studies on the comparison of these levels in wound patients with the activities of Raftlin, which is known to play a role in the vascular endothelial response. The aim of this study was to compare the levels of oxidative stress and antioxidant response between wound patients and a control group and to compare the levels of Raftlin between the two groups, which is a new biomarker in inflammatory diseases. Between January 2018 and September 2018, 30 healthy control patients and 30 patients with wounds were enrolled in the study as volunteers. Tissue samples were collected and were sent to the biochemistry laboratory to determine the levels of oxidative stress, antioxidant enzymes, and Raftlin, which play an important role in wound healing. The following were evaluated: SOD and CAT levels (as a measure of antioxidant enzymes); malondialdehyde (MDA) levels (as a measure of free oxygen radicals); and Raftlin, which is a lipid raft protein used in determining the level of inflammatory and autoimmune response. The analyses determined a statistically significant correlation between MDA, SOD, CAT, and Raftlin values in wound patients (p<0.05). Raftlin was a considerable parameter in determining the prognostic process of wound healing. The levels of tissue Raftlin were significantly higher in wounded patients. A significant increase in MDA, SOD, and CAT activities of the wounded patients also suggested that the oxidant and antioxidant effect was balanced and that external antioxidant supplementation was not required.

ABSTRACT

OBJECTIVE: Stuttering is a widespread but little understood disease. There has been a recent increase in neuropathophysiological, genetic, and biochemical studies related to the etiopathogenesis. As developmental stuttering continues in adult males, hormonal factors are thought to have an effect. In this study, an evaluation was made for the first time of serum GPER-1 level in patients with a stutter. STUDY DESIGN: Prospective case control. MATERIALS AND METHODS: The study included 30 patients with a stutter, aged < 18 years, and 35 age-matched children as the control group. The Stuttering Severity Instrument-3 form was administered to the patients. Evaluations were made of serum GPER-1, TSH, estradiol, prolactin, and progesterone and testosterone levels. RESULTS: GPER-1 level was determined as 0.51 (0.42-0.67) ng/mL in the patients and as 0.19 (0.13-0.25) ng/mL in the control group, and the difference was statistically significant (p < 0.001). A statistically significant difference was determined between genders with GPER-1 level of 0.56 (0.44-0.68) ng/mL in the male stuttering patient group and 0.44 (0.35-0.49) ng/mL in the female patient group (p = 0.026). Differential diagnosis with ROC analysis for the serum GPER-1 levels was statistically significant [Area under the ROC curve (AUC): 0.998, confidence interval, CI 0.992-1.000, p < 0.001]. CONCLUSION: The GPER-1 levels of the stuttering patients were found to be higher than those of the control group and GPER-1 levels of male patients were higher than those of females. As GPER-1 has high sensitivity and sensitivity, it could be considered important in the diagnosis and treatment of stuttering.

ABSTRACT

BACKGROUND: In our study, we aimed to evaluate the serum homocysteine levels, pyridoxine, folate and vitamin B12 levels in children with attention deficit hyperactivity disorders (ADHD). SUBJECTS AND METHODS: This study included 30 newly diagnosed drug-naive children with ADHD (23 males and 7 female, mean age 9.3±1.8 years) and 30 sex-and age matched healthy controls. The diagnosis of ADHD was made according to DSM-V criteria. Children and adolescents were administered the Schedule for Affective Disorders and Schizophrenia for School Aged Children, Present and Lifetime Version, the Conners' Parent Rating Scale-Revised, Long Form, the Conners' Teacher Rating Scale and the Wechsler Intelligence Scale for Children Revised (WISC-R) for all participants. Homocysteine, pyridoxine, folate and vitamin B12 levels were measured with enzyme-linked immunosorbent assay. RESULTS: Homocysteine, pyridoxine, folate and vitamin B12 levels were significantly lower in children with ADHD compared with their controls (p<0.05). A positive significant correlation was observed between the all WISC-R scores and vitamin B12 level in patients (r=0.408, p=0.025). CONCLUSIONS: The results obtained in this study showed that reduced homocysteine, pyridoxine, folate and vitamin B12 levels could be a risk factor in the etiology of ADHD.

ABSTRACT

INTRODUCTION: To the best of our knowledge, no previous study regarding the serum telomerase levels in Maras powder users (MPUs) has been founded. The aim of the current study was to investigate serum telomerase levels in smokers and MPUs. MATERIALS AND METHODS: The study was carried out with 98 patients (36 MPUs, 32 smokers and 30 non-smokers). Blood samples were collected, and after having measured the serum telomerase and malondialdehyde (MDA) levels of the patients, comparison were made between the groups. RESULT: It has been observed that the serum telomerase and MDA levels of smokers (p< 0.001) and MPUs (p< 0.001) were significantly higher compared to those of the non-smoker control subjects. In addition, the levels of serum telomerase and MDA were observed to be higher in the MPU group compared to those of the smoker group (p< 0.001). CONCLUSIONS: The levels of serum telomerase and MDA were observed to be higher among MPUs and smokers. In this context, it may be useful to further measure and assess telomerase activity in such patients in order to better determine the harmful effects associated with these habits.

ABSTRACT

BACKGROUND: Tinea pedis (TP) is an infection of the feet caused by fungi. The infectious diseases caused by dermatophytes are mainly related to the enzymes produced by these fungi. Up to the now, the local 8-iso-prostaglandin F2α (8-iso-PGF2α), concentration as oxidative stress biomarker and trace elements status have not been published in patients with TP. The aim of this study is to evaluate the relationship between oxidative stress and trace elements (Cu, Zn, Se), and to evaluate the ratios of Cu/Zn and Cu/Se in this disorder. METHODS: Forty-three consecutive patients with a diagnosis of unilateral interdigital TP were enrolled in this study. The samples were obtained by scraping the skin surface. 8-iso-PGF2α concentrations in scraping samples were determined by ELISA. In addition, the levels of Se, Zn and Cu in scraping samples were determined on flame and furnace atomic absorption spectrophotometer using Zeeman background correction. RESULTS: Oxidative stress was confirmed by the significant elevation in 8-iso-PGF2α concentrations (p < 0.05). When compared to non-lesional area, Zn and Se levels were significantly lower on lesional area, whereas Cu levels was higher on the lesional area than the non-lesional area (p < 0.05). In addition, the correlation results of this study were firstly shown that there were significant and positive correlations between Cu and 8-iso-PGF2α parameters, but negative correlations between Se-Cu; Se-8-iso-PGF2α parameters in lesional area. Furthermore, the ratios of Cu/Zn and Cu/Se were significantly higher on the lesional area than the non-lesional area (p < 0.05). According to sex and fungal subtypes, there was no significant difference in the concentrations of 8-iso-PGF2α and trace elements in patients with TP (p > 0.05). CONCLUSIONS: Our results showed that there is a possible link between oxidative stress (increased 8-iso-PGF2α concentrations) and imbalanced of trace elements status in lesional area of TP patients. The use of antifungal agents together with both Zn and Se drugs could be helpful in the both regression of disease and in shortening the duration of disease.

ABSTRACT

Remarkable interest has risen in the idea that oxidative/nitrosative stress is mediated in the etiology of numerous human diseases. Oxidative/Nitrosative stress is the result of an disequilibrium in oxidant/antioxidant which reveals from continuous increase of Reactive Oxygen and Reactive Nitrogen Species production. The aim of this review is to emphasize with current information the importance of antioxidants which play the role in cellular responce against oxidative/nitrosative stress, which would be helpful in enhancing the knowledge of any biochemist, pathophysiologist, or medical personnel regarding this important issue. Products of lipid peroxidation have commonly been used as biomarkers of oxidative/nitrosative stress damage. Lipid peroxidation generates a variety of relatively stable decomposition end products, mainly α, ß-unsaturated reactive aldehydes, such as malondialdehyde, 4-hydroxy-2-nonenal, 2-propenal (acrolein) and isoprostanes, which can be measured in plasma and urine as an indirect index of oxidative/nitrosative stress. Antioxidants are exogenous or endogenous molecules that mitigate any form of oxidative/nitrosative stress or its consequences. They may act from directly scavenging free radicals to increasing antioxidative defences. Antioxidant deficiencies can develop as a result of decreased antioxidant intake, synthesis of endogenous enzymes or increased antioxidant utilization. Antioxidant supplementation has become an increasingly popular practice to maintain optimal body function. However, antoxidants exhibit pro-oxidant activity depending on the specific set of conditions. Of particular importance are their dosage and redox conditions in the cell.

ABSTRACT

Yeast of Malassezia, members of the microbiologic flora of the skin, cause pityriasis versicolor and have also been implicated in the pathogenesis of other superficial dermatoses. The mechanisms by which the yeast cause these dermatoses, however, are not yet clear, and there have been no studies on the interaction between fungi and keratinocytes, especially the effects of fungi on the production of reactive oxygen/nitrogen species by human keratinocytes. This is the first study we aimed to evaluate the role of oxidative/nitrosative stress in affected skin areas in patients with pityriasis versicolor. Sixty pityriasis versicolor patients and 60 healthy subjects as control group were enrolled. Scraping samples were obtained from the lesional skin areas in patients and from the normal skin areas in controls. The distribution of lesions of pityriasis versicolor was mild in all patients. We have isolated two Malassezia species: M. furfur being isolated in 75% of patients, followed by M. globosa (25%). The levels of oxidative/nitrosative stress biomarkers were significantly higher in patients than the controls (P < 0.001). Our results demonstrated that pityriasis versicolor is associated with significant alteration in oxidant/antioxidant balance. It might be secondary consequence of pityriasis versicolor infection or contributing factor in its pathogenesis.

ABSTRACT

BACKGROUND: Oxidative stress biomarkers such as superoxide dismutase (CuZnSOD), catalase (CAT) and malondialdehyde (MDA) play an important role in the pathogenesis or progression of numerous diseases. Data regarding the biological variation and analytical quality specifications (imprecision, bias and total error) for judging the acceptability of method performance for oxidative stress biomarkers in urine are conspicuously lacking in the literature. Such data are important in setting analytical quality specifications, assessing the utility of population reference intervals (index of individuality) and assessing the significance of changes in serial results from an individual (reference change value; RCV). MATERIALS AND METHODS: 20 patients with type 2 diabetes mellitus (T2DM), 20 patients with diabetic nephropathy (DN) and 14 healthy individuals as control were involved in this study. Timed first morning urine samples were taken from patients and healthy groups on the zero, 1st, 3rd, 5th, 7th, 15th and 30th days. Index of individuality and reference change value were calculated from within-subject and between-subject variations. Methods of oxidative stress biomarkers in human blood were adopted in human urine and markers were measured as spectrophotometrically. Also, analytical quality specifications for evaluation of the method performance were established for oxidative stress biomarkers in urine. RESULTS: Within-subject variations of oxidative stress biomarkers were significantly higher in patients with DN and T2DM compared to healthy subjects. MDA showed low individuality, and within-subject variances of MDA were larger than between-subject variances in all groups. However, CAT and CuZnSOD showed strong individuality, but within-subject variances of them were smaller than between-subject variances in all groups. RCVs of all analytes in diabetic patients were relatively higher, because of high within-subject variation, resulting in a higher RCV. Also, the described methodology achieves these goals, with analytical CVs of < 3.5% for all analytes. Goals for bias and total error were 6.0-7.9% and 12.5-23.3%, respectively. CONCLUSIONS: RCVs concept for predicting the clinical status in diabetic patients represents an optimization of laboratory reporting and could be a valuable tool for clinical decision. Furthermore, for oxidative stress biomarkers' measurements in urine, the desirable imprecision goals based on biological variation are obtainable by current methodologies.

ABSTRACT

OBJECTIVE: The aim of this study was to examine the association between Raftlin and Presepsin levels in periodontal healthy/diseases, hypothesizing a change in their levels. Also, the study aimed to determine their potential role in diagnosing and predicting the prognosis of periodontal diseases. DESIGN: A cross-sectional study design was used, including 20 periodontally healthy individuals, 21 gingivitis patients, and 21 periodontitis patients. Clinical measurements and gingival crevicular fluid (GCF) sample collection were conducted, and the levels of Raftlin and Presepsin were analyzed. Statistical analysis was performed to evaluate the differences and correlations among the groups. RESULTS: Raftlin and Presepsin levels displayed significant variations among groups in both total amount (mean values for Raftlin in periodontitis, gingivitis, and healthy were 33.42, 17.45, 7.70 pg/30 s, respectively; for Presepsin, values were 3.98, 3.01, 1.92 pg/30 s, respectively) (p < 0.001) and concentration levels (pg/µl) (p = 0.007 for Raftlin, p = 0.026 for Presepsin). Particularly noteworthy were the concentration distinctions observed exclusively between the periodontitis and healthy groups. CONCLUSIONS: The present study offers preliminary insights into the presence and variations of raftlin and prepsepsin in the GCF across different periodontal conditions. While these findings hint at a potential role for these markers in periodontal disease, further research is essential to fully understand their diagnostic and prognostic capabilities.

ABSTRACT

Hydrogels prepared with natural and synthetic polymers were found to be applicable for the development of resistance against some Gram positive and negative bacterial species. Numerous studies have shown that chitosan polymers can be advantageous to be used in medicine due to their high antibacterial activity. In this study, biocompatible yellow cantorone oil doped hydrogels (chitosan/poly(vinyl alcohol) based) with antimicrobial properties were synthesized. The structural, morphological, swelling and mechanical properties of these biocompatible hydrogels prepared by double crosslinking were investigated and characterized. FTIR spectroscopy showed the appearance of new imine and acetal bonds due to both covalent cross-linking. In vitro cytotoxicity evaluation revealed that hydrogels showed weak cytotoxic effect. In the antimicrobial evaluation, it was determined that the hydrogel containing only chitosan showed better antimicrobial effect against Escherichia coli, Pseudomonas auriginosa, Staphylococcus aureus and Enterococcus faecalis bacteria than the one containing St. John's Wort oil. The antibacterial effect of polyvinyl alcohol/chitosan hydrogel was low. In our wound healing study, chitosan hydrogel loaded with yellow St. John's Wort oil was more effective in reducing wound size.

ABSTRACT

Objective: Generalized anxiety disorder (GAD) is a prevalent psychiatric disorder. Diagnosis of GAD depends on subjective complaints of patients, thus the need for biological markers is constantly emerging. In this study, we aimed to the investigate diagnostic values of Erythropoietin (Epo) and its receptor (EpoR) levels in drug-naïve patients with GAD. Methods: This study included 45 newly diagnosed drug-naive patients with GAD, aged and sex-matched 30 healthy controls. Medical histories were obtained, and physical examinations and laboratory tests were conducted. Also, the Hamilton Anxiety Rating Scale (HAM-A) was used for all participants. Serum Epo and EpoR levels were measured by ELISA. Results: HAM-A score was significantly higher in GAD patients versus the controls (p < 0.05). While the levels of Epo in patients with GAD were lower than the control patients, EpoR levels were increased in these patients (p < 0.05). Epo/EpoR ratios were significantly lower in the patients with GAD than in the control subjects (p < 0.05). A positive significant correlation was observed between the EpoR level and the HAM-A score (r = 0.755, p < 0.001). However, there was a negative significant correlation between Epo levels and HAM-A score (r = -0.749, p < 0.001). Receiver operator characteristic curve analysis showed high diagnostic performance for Epo and EpoR, areas under curves were 0.901 and 0.912, respectively. Conclusion: This is the first report to investigate the association between serum Epo and EpoR levels in GAD patients. Our results reveal possible diagnostic value of Epo and EpoR. Moreover, Epo therapy may be a good choice for GAD treatment.

ABSTRACT

Objective: Although there are neurobiological studies of patients with generalized anxiety disorder (GAD), the topic is still open to research. Lipid peroxidation can generate new molecular signal sequences by altering protein amounts and activity. 8-Iso-Prostaglandin F2α (8-iso-PGF2α) is known to be an important lipid peroxidation marker. Raftlin, which is defined as a major lipid raft protein, is important for the regulation of signal transduction and inflammatory processes. Methods: Our aim in this study was to compare the 8-iso-PGF2α and Raftlin levels of forty patients diagnosed with GAD and 40 healthy controls (age-sex and body mass index-matched). Results: In the present study, increased serum 8-iso-PGF2α and Raftlin levels were found in patients with GAD compared to healthy controls. Conclusion: To our knowledge, this is the first study to examine 8-iso-PGF2α and Raftlin levels in patients with GAD. These results expand our knowledge of oxidative stress and inflammatory processes in patients with GAD. Our study should be considered preliminary and further studies should be performed with larger sample groups comparing values before and after treatment.

ABSTRACT

Aims: This paper aimed to investigate the antiviral drugs against Sars-Cov-2 main protease (MPro) using in silico methods. Material and Method: A search was made for antiviral drugs in the PubChem database and antiviral drugs such as Bictegravir, Emtricitabine, Entecavir, Lamivudine, Tenofovir, Favipiravir, Hydroxychloroquine, Lopinavir, Oseltamavir, Remdevisir, Ribavirin, Ritonavir were included in our study. The protein structure of Sars-Cov-2 Mpro (PDB ID: 6LU7) was taken from the Protein Data Bank (www.rcsb. Org) system and included in our study. Molecular docking was performed using AutoDock/Vina, a computational docking program. Protein-ligand interactions were performed with the AutoDock Vina program. 3D visualizations were made with the Discovery Studio 2020 program. N3 inhibitor method was used for our validation. Results: In the present study, bictegravir, remdevisir and lopinavir compounds in the Sars-Cov-2 Mpro structure showed higher binding affinity compared to the antiviral compounds N3 inhibitor, according to our molecular insertion results. However, the favipiravir, emtricitabine and lamuvidune compounds were detected very low binding affinity. Other antiviral compounds were found close binding affinity with the N3 inhibitor. Conclusion: Bictegravir, remdevisir and lopinavir drugs showed very good results compared to the N3 inhibitor. Therefore, they could be inhibitory in the Sars Cov-2 Mpro target.

ABSTRACT

BACKGROUND: The aim of this study was to investigate the prophylactic and therapeutic effects of Arum dioscoridis (tirsik) plant extract against thioacetamide-induced experimental liver toxicity. METHODS: In this study, 35 male Wistar-Albino rats, of 12-14 weeks old, weighing between 200 and 270 g, were used. Rats were divided into 5 groups of 7 each. The first group was determined as the control group, the second group as the hepatotoxicity group, the third group as the prophylaxis group, the fourth group as the intraperitoneal treatment group, and the fifth group as the oral treatment group. Hepatotoxicity was achieved with a single intraperitoneal dose of 350 mg/kg of thioacetamide (TAA). On the seventh day, the rats were sacrificed under general anesthesia. Their blood was taken and liver enzymes were studied. Malondialdehyde (MDA), glutathyon peroxi dase (GPx), catalase (CAT), superoxit dismutase (SOD) enzymes were studied from liver tissues. In addition, liver tissues were evaluated histopathologically. RESULTS: With Arum dioscoridis treatment and prophylaxis, improvements in all parameters and increases in tissue antioxidant levels were detected. CONCLUSION: It was determined that Arum dioscoridis plant extract has prophylactic and therapeutic effects on liver toxicity. In cases of acute liver injury and hepatotoxicity, we suggest the potential application of Arum dioscoridis for effective and inexpensive treatment.

ABSTRACT

Bioactive compounds found in plants also have pharmacological antiviral effects. Berberine (BBR), an alkaloid found naturally in plants, is one of the phytochemicals with a wide range of biological activities, including antiviral, anticancer, anti-inflammatory and anti-inflammatory. In this study, we firstly aimed to predict pIC50 values for selcted compounds and then extract the binding patterns of berberine and its derivatives in the Sars Cov-2 Master Protease structure via employing molecular docking approache. Our results showed that berberine and its derivatives have good binding affinities towared Sars Cov2 main protease protein. Based on docking results the pharamaccokinetic studies for berberine, berberrubine, demethylen-berberine, jatrorrhizin, and thalifendine, were conducted and showed a good pharamacokinetic properties as an oral drugs. For deep inspection, we utiilized molecular dynmaics simulation to examine the Sars Cov2 main protease-ligand stabilities. The molecular dynamics simulation and PCA investigations revealed that thalifendine have a strong willing to act as good bindinder to SARS-CoV-2 protease. Further, the network based pharamacology showed that these drugs mediate different pathways such as human T-cell leukemia virus 1 infection, viral carcinogenesis, human immunodeficiency virus 1 infection, kaposi sarcoma-associated herpesvirus infection and epstein-Barr virus infection.The findings of this study have an important recomendation for thalifendine for more in vivo and in vitro studies to work.Communicated by Ramaswamy H.

ABSTRACT

INTRODUCTION: Biological factors are known to be important in understanding the pathogenesis of Major Depressive Disorder (MDD). Oxidative stress and neuroinflammation pathways are likely to play a critical role here. METHODS: We undertook a study to investigate two novel biomarkers - serum NADPH oxidase 1 (NOX1) and Raftlin levels - in treatment-naive, smoking-free first episode patients with MDD compared to healthy controls (HCs) matched for age, sex and body mass index. RESULTS: We found increased NOX1 and Raftlin levels in MDD patients compared to HCs. Both parameters showed very good diagnostic performance in the MDD group. In addition, we found a significant positive correlation between depression severity (HAMD) scores and both biomarker levels in the patient group. CONCLUSION: To the best of our knowledge, this is the first human study to evaluate serum NOX1 and Raftlin levels in depression. NOX1, an important source of reactive oxygen species (ROS), and Raftlin, which may play a role in the inflammatory process, represent novel potential biomarkers of MDD. These findings support the implication of oxidative stress and inflammatory processes in patients with MDD, and indicate that the deteriorated ROS-antioxidant balance can be regulated via NOX1 in patients with depression.
