Systemic lupus erythematosus (SLE) is an autoimmune disease with unknown exact etiology. Vitamin D receptor gene ( VDR) and oxidative stress play important roles in the pathogenesis of SLE. Here we investigated the genotypes and allelic frequencies of VDR BsmI polymorphism as well as their relationship with oxidative stress markers in Egyptian SLE children. We conducted a cross-sectional comparative study at Mansoura University Children's Hospital, Egypt from 2014 to 2018 including 100 SLE children and 100 controls. We investigated both groups for VDR BsmI polymorphism using polymerase chain reaction. Oxidative stress was assessed using malondialdehyde, glutathione S-transferase, superoxide dismutase, catalase and total antioxidant capacity. BB genotype frequency was found to be significantly higher in the SLE group ( p = 0.04, odds ratio (95% confidence interval) = 2.5 (1.01–5.9)). However, VDR B allele and b allele showed insignificant differences between SLE patients and controls ( p = 0.36, odds ratio (95% confidence interval) = 1.2 (0.8–1.8)). Lower levels of glutathione S-transferase, superoxide dismutase and total antioxidant capacity were found in the SLE group with statistically significant differences as regards glutathione S-transferase and superoxide dismutase ( p < 0.001). Serum malondialdehyde and catalase levels were significantly higher in the SLE group ( p < 0.001). No significant differences were found between VDR BsmI polymorphism (genotypes and alleles) and oxidative stress markers in the SLE group. In conclusion, BB genotype of VDR BsmI polymorphism is associated with an increased risk of SLE among Egyptian children. Oxidative stress may contribute in pathogenesis of SLE but is not associated with VDR BsmI polymorphism.

Background: One of the most common complications of pregnant women is gestational diabetes mellitus (GDM). Oxidative stress can play an important role in GDM. Objective: The aim of this study was to evaluate salivary antioxidants and oxidative stress markers in GDM. Method: Twenty pregnant women with GDM and 20 healthy pregnant women with normal blood glucose test participated in this study. Five mL of unstimulated saliva samples were collected. Spectrophotometric assay was carried out for sialochemical analysis. Stata software was used for data analysis. Results: The GDM group exhibited no significant difference in salivary total antioxidant capacity and malondialdehyde compared to the healthy control group. All of antioxidants markers, the uric acid, total antioxidant, peroxidase and catalase, decreased in GDM group that the difference of peroxidase and catalase was statistically significant. All of oxidative stress markers, the salivary malondyaldehid, total oxidative stress and total thiol, increased in GDM group. GDM group exhibited significantly higher salivary total oxidative stress levels. Conclusion: Catalase level was significantly lower and total oxidative stress was significantly higher. These two markers might have significant importance and might exhibit early changes compared to other factors in GDM. . Some of salivary antioxidants might have diagnostic, prognostic or therapeutic implications in GDM. Other studies with large sample size on salivary and blood samples need to be done to confirm this properties and salivary samples using instead of blood samples in GDM biomarkers changes.

Gold nanoparticles (GNPs) are the most commonly used metal nanoparticles due to their promising characteristics. However, application of GNs in medical and biological fields has resulted in toxicity to several organs. Indole-3-carbinol (I3C) and sulforaphane (SF) are the two well-known natural compounds, largely present in cruciferous vegetables. This study aimed to explore the therapeutic efficacy of I3C and SF alone or in combination against GN-induced renal and cardiac toxicities. Fifty male Albino rats were randomly segregated into five groups with each group containing 10 rats; G1, control; G2, intraperitoneally administered with a suspension of GNPs (10 nm in size; 20 µg/kg body weight (b.w.) for 7 days; G3, GN-injected rats, supplemented with SF (5 mg/kg b.w) daily for 7 days; G4, GN-injected rats, supplemented orally with I3C (150 mg/kg b.w.) for 7 days and G5, GN-injected rats supplemented orally with SF and I3C daily for 7 days. GN treatment significantly disturbed kidney functional markers, as evidenced by significantly increased levels of urea, creatinine and creatine kinase. Additionally, GNs significantly increased renal and cardiac levels of malondialdehyde, 8-hydroxydeoxyguanosine and interleukin-6, and depleted, glutathione S-transferase, glutathione reductase, superoxide dismutase, total antioxidant capacity, and nuclear factor erythroid 2-related factor 2. In contrast, treatment with I3C and SF alone or in combination significantly restored all the parameters to their near normal levels. GN induced histological abnormalities were also significantly attenuated. Taken together, the data indicate that the SF and I3C are more effective when given separately than when given together in lowering GN-induced toxicity by their ability to alleviate oxidative stress and inflammation.

Hucul and Arabian horses differ in the physiological constitution and exposition to environmental conditions. Oxidative stress plays a pathogenic role in many diseases and enables further injuries. The objective of this study was to compare the levels of enzymatic and nonenzymatic oxidative stress markers in Hucul horses living in seminatural conditions and in commercially handled Arabian horses. We tested the serum samples for total superoxide dismutase (total SOD), Cu-Zn-superoxide dismutase (CuZnSOD), and Mn-dependent superoxide dismutase (MnSOD) activity; for lipofuscin (LPS), ceruloplasmin (CER) and malondialdehyde (MDA) concentration; and for total antioxidant capacity (TAC) and total oxidant status (TOS). Total SOD (p<0.001), MnSOD (p<0.001), and CuZnSOD (p<0.001) activities were significantly higher whereas LPS (p<0.05), TAC (p<0.001), TOS (p<0.001), and MDA (p<0.001) concentrations were significantly lower in the serum samples collected from Huculs vs. Arabian horses, regardless of the gender. Gender, regardless of the breed, had no significant impact on the antioxidants’ activity and concentration. Total SOD and MnSOD activities were significantly higher in Hucul’s mares when compared to Hucul’s stallions. Concentrations of TAC and TOS were significantly lower in Arabian stallions than in Arabian mares. Commercially handled horses expressed a higher level of oxidative stress markers in comparison to breeds living in seminatural conditions. We conclude that antioxidants are important biomarkers of animal health, whether they are under maintenance care or performing physical exercise.

Objective. The aim of the study was to estimate the impact of whole-body cryotherapy (WBC) and subsequent kinesiotherapy on oxidative stress and lipid profile when performed in a closed cryochamber on healthy subjects. Material and Methods. The effect of ten WBC procedures lasting 3 minutes a day followed by a 60-minute session kinesiotherapy on oxidative stress and lipid profile in healthy subjects (WBC group, n=16) was investigated. The WBC group was compared to the kinesiotherapy only (KT; n=16) group. The routine parameters of oxidative stress (antioxidant enzymatic and nonenzymatic antioxidant status, lipid peroxidation products, total oxidative status (TOS), and oxidative stress index (OSI)) and lipid profile were estimated one day before the beginning and one day after the completion of the research program. Results. After treatment, in the WBC group, a significant decrease of oxidative stress markers (TOS and OSI) and a significant increase of total antioxidant capacity were observed. The activity of plasma SOD-Mn and erythrocyte total SOD increased significantly in the WBC group. In the KT group, the erythrocyte activity of total SOD, CAT, and GR decreased significantly after the treatment. The levels of T-Chol and LDL-Chol decreased significantly after treatment in both groups, but the observed decrease of these lipid parameters in the WBC group was higher in comparison to the KT group. The level of TG decreased significantly after treatment in the WBC group only. Conclusion. WBC performed in a closed cryochamber followed by kinesiotherapy improves lipid profile and decreases oxidative stress in healthy subjects.

Abstract Objectives Osteoarthritis (OA) is an inflammatory disorder of the joint characterized by pain and stiffness. Oxidative stress plays an important role in pathogenesis of OA. We aimed to evaluate the effects of avocado/soy unsaponifiables (ASU) compound on serum antioxidant and oxidative stress in patients with Osteoarthritis. Methods A double-blind, randomized, placebo-controlled, cross-over trial was performed. Fourty patients with osteoarthritis were randomized to two different sequences: 1) DP: received ASU for three months followed by three months placebo, 2) PD: received placebo for the first three months followed by three months ASU. The oxidant statue was evaluated by measurement of serum malonldialdehyde (MDA). The total antioxidant capacity (TAC), reduced glutathione (GSH) and antioxidant enzymes such as superoxide dismutase (SOD) and catalase (CAT) were also assessed. Results Mean serum of MDA level as a marker of oxidative stress significantly decreased in all patients after three months treatment with ASU (4.46 ± 0.11 nmol/L) compare with baseline and placebo levels (5 ± 0.15 and 5.82 ± 0.12 nmol/L respectively) (p<0.05). On the other hand, ASU resulted in positive changes in serum antioxidant levels (p<0.05). Mixed-effects model of variance analyses showed that ASU effect is regardless of the order of receiving medication (p>0.05). Conclusions These data showed that Avocado/Soy Unsaponifiable can be an effective supplement in treatment of osteoarthritis through the control of the balance between antioxidant and oxidant molecular markers.

Statins provide greater protection than predicted from just cholesterol-lowering effects, which is possibly mediated by other pleiotropic actions. This study aimed to examine the possible interaction effect of asthma on lipid profiles and evaluate the effect of rosuvastatin treatment on asthma. The animals were assigned into (1) control, (2) asthmatic, (3) hyperlipidemic, (4) asthmatic-hyperlipidemic, (5) rosuvastatin (40 mg/kg/day intraperitoneally, for 3 weeks)-treated asthmatic, (6) rosuvastatin-treated hyperlipidemic and (7) rosuvastatin-treated asthmatic-hyperlipidemic groups. Tracheal responsiveness to methacholine and ovalbumin, total and differential WBC (white blood cell) counts, and oxidative stress markers in bronchoalveolar lavage fluid (BALF) were evaluated. In the asthmatic and asthmatic-hyperlipidemic groups, tracheal responsiveness to ovalbumin, total WBC count, numbers of eosinophils, neutrophils, and monocytes were higher than the control group (p<0.001). A left-ward shift in the concentration-response curves to methacholine, an increase in nitrite and malondialdehyde concentrations, and a decrease in total thiol content, superoxide dismutase and catalase activities were also observed in the asthmatic and asthmatic-hyperlipidemic groups compared to control group (p<0.01 to p<0.001). Beyond lipid-lowering effect in the treated hyperlipidemic and asthmatic-hyperlipidemic groups, rosuvastatin treatment decreased tracheal responsiveness to methacholine, reduced total WBC count, the numbers of eosinophils, neutrophils, and monocytes, as well as decreased malondialdehyde concentration, and increased total thiol content, superoxide dismutase and catalase activities in treated asthmatic and asthmatic-hyperlipidemic groups (p<0.05 to p<0.001). The improving effect of rosuvastatin on asthmatic and asthmatic-hyperlipidemic animals was shown due to pleiotropic mechanisms including the effect on airway hyperresponsiveness, lung inflammation, and oxidative stress.

Introduction: Receptor activator of nuclear factor κB ligand (RANKL), osteoprotegerin (OPG), and oxidative stress markers are suggested to contribute to bone loss in osteoporosis that occurs in menopause. However, the association between these markers and bone mineral density (BMD) is controversial. The aim of this study was to measure circulatory levels of these parameters in postmenopausal women with normal or low BMD. Methods: The study population included 71 postmenopausal women, of whom 25 had normal BMD, 31 had osteopenia, and 15 had osteoporosis. Serum levels of RANKL, OPG, and 5 oxidative stress markers (catalase, peroxiredoxin 2 [PRX2], superoxide dismutase 1 [SOD1], superoxide dismutase 2 [SOD2], and thioredoxin [TRx1]) were measured using the Multiplex system. Results: As compared with subjects having normal BMD, subjects with low BMD had significantly lower median serum levels of OPG, catalase, SOD2, and PRX2 ( P = .004, .031, .044, and .041 respectively). Although levels of RANKL were not different between the 2 groups, the RANKL/OPG ratio was higher in women with low BMD ( P = .027). Conclusions: These data provide insights into the possible roles of OPG, RANKL, and oxidative stress in the pathogenesis of postmenopausal osteoporosis. However, the lack of association between these markers and BMD indicates that osteoporosis is complex and multivariate.

Abstract Background Sexual dimorphism in metabolic and oxidative stress markers of Clarias gariepinus and Heterobranchus longifilis found in southwest Nigeria was investigated. C. garepinus and H. longifilis broodstock weighing 2.54 ± 0.12 and 2.11 ± 0.15 kg consisting of 20 males and females each per species were sourced from southwest Nigeria. Fishes conditioned conditioning for breeding, blood samples were collected, and serum obtained to assess metabolic and oxidative stress indices using standard procedures. Results The results obtained show that serum albumin, triglyceride, low-density lipoprotein, alanine aminotransferase, and total antioxidant activity of Clarias garepinus were significantly (p < 0.05) higher than Heterobranchus longifilis. Superoxide dismutase of males was significantly (p < 0.05) superior to females in both species. The total antioxidant activity of males was significantly (p < 0.05) superior to females in Heterobranchus longifilis. Serum catalase, glutathione peroxidase and lipid peroxidation were not affected by sex and species differences. Superoxide dismutase activity and some non-enzyme antioxidants could account for superior total antioxidant activity in males despite similar lipid peroxidation. Conclusion Catfish broodstocks of Heterobranchus longifilis possess superior total antioxidant activity than Clarias gariepinus owing to its superior non-enzyme antioxidants fraction. In both clariid species, males have better antioxidant defence than females.
