Sodium propanoate is in the list of approved feed preservatives. However, there is dearth of information on its biological effects on the C. gariepinus. The present study investigated the effect of sodium propanoate-preserved feed on the hepatic histomorphometric changes, oxidative stress and inflammatory parameters of C. gariepinus juveniles. One hundred juveniles of mixed sexes, assigned into 5 groups of 20 fish per group, with each group consisting of 2 replicates of 10 fish, were used for the investigation. Group A juveniles were fed basal diet, while groups B-E received basal diet incorporated with sodium propanoate at the rate of 25, 50, 75 and 100 g/15 kg of feed respectively. Treatments were done two times daily for 8 weeks. Samples (sera and liver) were collected on the last day for evaluation of a few biochemical parameters (malondialdehyde values, catalase activity, C-reactive protein levels) and histomorphometric alterations in the liver. Results indicated that fish in groups D and E had higher catalase activities, lower serum levels of C-reactive proteins and an intact hepatic histomorphormetry when compared with the control group. There was no significant difference in the plasma malondialdehyde values in all the groups. It was concluded that preservation of fish feed with sodium propanoates improved antioxidant status of C. gariepinus and protected liver histology.

Objective: The production of reactive oxygen species in exercise causes oxidative stress which disturbs the balance of oxidants and antioxidants, causing destructive effects on cells. The present study aims to investigate the effect of three types of massage (Swedish, Russian, Thai) on serum levels of Malondialdehyde (MDA), Glutathione Peroxidase (GPX) and Superoxide Dismutase (SOD) following one session of exhaustive exercise. Methods: This quasi-experimental study was conducted on 48 female futsal players aged 17-22 years in Zahedan, Iran who were selected using a purposive sampling method, and randomly divided into four groups of Swedish massage (Long strokes with pressing and tapping using hands), Russian massage (Medium to high pressure), Thai massage (Pressure to certain parts of the body) and Control. The exercise program was based on Bruce protocol. Serum levels of MDA, GPX and SOD were measured by before and immediately after exercise and after massage. Data analysis was performed using repeated measures ANOVA, considering a significance level of P≤0.05. Results: In all three types of massage, there was a significant decrease in serum level of MDA (0.22±0.08), and a significant increase in GPX (1.84±0.46) and SOD (10.02±2.86) levels after exhaustive (P=0.001). No significant difference was observed in the control group. Conclusion: It seems that Russian, Thai, and Swedish types of massage can affect the serum levels of the MDA (as an oxidative stress marker) and the antioxidant enzymes of GPX and SOD during the post-exercise recovery period.

This study was to compare the impact of different biocompatible coated circuits on inflammatory response and oxidative stress induced during cardiopulmonary bypass (CPB). Seventy-eight patients undergoing elective coronary artery bypass grafting (CABG) with CPB were randomly assigned to five groups with different biocompatible coated circuits: Trillium, Bioline, Phosphorylcholine, Polymethoxyethyl acrylate (PMEA), and the uncoated control group. Blood was drawn at three different time points: before CPB, 6 and 72 hours post CPB. Unlike the Trillium group, serum levels of TNF-α in the Bioline and Phosphorylcholine groups significantly increased only at 72 hours post CPB (p < 0.05). Serum levels of IL-6 significantly increased at 6 and 72 hours post CPB in all groups (p < 0.01). The Trillium group showed a significant increase of IL-10 compared to the control group at 72 hours post CPB (p < 0.05). Serum levels of NOx in the Phosphorylcholine group significantly decreased at 6 hours post CPB compared to baseline (p < 0.05). Both the Bioline and Phosphorylcholine groups showed statistical decreases in serum NOx levels compared with other groups at 6 hours post CPB (p < 0.05). A significant difference in NOx levels between the Bioline and the control group was also observed at 72 hours post CPB. Myeloperoxidase levels were significantly elevated at 6 and 72 hours post CPB in all groups (p < 0.05). Inflammatory response and oxidative stress are elevated during CABG with CPB. Heparin-coated and the Phosphorylcholine-coated circuits induce less inflammatory responses and oxidative stress compared to other circuits.

Background: The pathogenesis of endometriosis remains unclear, and involves multifactorial etiologies. The increase in oxidative stress is known to be associated with this disease. Oxidative stress increases angiogenesis and supports the proliferation of endometriosis tissue in the peritoneal cavity. Kebar grass, a medicinal plant, is expected to increase antioxidant defense resulting in decreased oxidative stress, inflammation, angiogenesis, and reduced endometrial tissue implants.   Objective: To investigate the effects of Kebar grass extract administration to MDA serum levels, TNF-a and VEGF expression, and the extension of the endometriotic lesions in mice model.   Methods: This study was experimentally designed. It was conducted in the Department of Obstetrics Gynecology, Faculty of Medicine Diponegoro, University and Faculty of Veterinary Medicine, Airlangga University. Twenty-one mice were divided into three groups: the first group is control of 7 untreated endometriosis mice model, the second group consisted of 7 mice injected with leuprolide acetate 1mg/kgBB single dose, and the last group consisted of 7 mice fed with Kebar grass extract 3mg/day for 14 days. MDA serum level was measured by spectrophotometry, TNF-a  and VEGF expression by IHC using Rammele Scale Index (ImmunoReactive Score), whereas the extension of the endometriotic lesions was measured using computerize tracing.   Results: Both Kebar grass extract and leuprolide acetate administration significantly decrease MDA serum levels in endometriosis mice model, compare with the control group, (0.09±0.02 nmol, 0.11±0.07 nmol, and 0.30±0.06 nmol, respectively; p=0.001). TNF-α expression of the group treated with Kebar grass extract was lower than leuprolide acetate and control group (2.43±1.521 %, 4.86±0.458 %, and 7.26±2.898 %, respectively; p=0.002). However, there was no significant difference in VEGF expression among study groups (4.34±2.40 %, 5.11±1.95 %, and 7.40±3.49 % respectively; p=0.116). Finally, the extension of the endometriotic lesions of the mouse models administered with Kebar grass extract and leuprolide acetate was smaller than the control group (0 mm2, 4.54±7.75 mm2, and 34.80±13.09 mm2 respectively; p=0.005).   Conclusion: Kebar grass extract has the effect of decreasing MDA serum levels and reducing TNF-α expression, resulted in smaller endometriotic lesions in mice, even though it does not affect VEGF expression.   Keywords: malondialdehyde, tumour necrosis factor alpha, vascular endothelial growth factor, endometriotic lesion, kebar grass extract, endometriosis mouse

Aim. We aimed to evaluate the antioxidant effects of weight loss and melatonin on the obesity-induced oxidative damage in rat testes.Materials and Methods. 28 male Wistar albino rats were randomly divided into 4 groups, each consisting of 7 rats: control group (Group 1), obesity group (Group 2), obesity + MLT group (Group 3), and weight loss group (Group 4). Rats were weighed at the beginning and at the end of the study. Bilateral orchiectomy was performed and 5 cc blood samples were obtained from all of the rats. Superoxide dismutase (SOD), malondialdehyde (MDA), and protein carbonyl (PC) levels were analysed in the testicular tissues and serum. Spermatogenesis was evaluated with the Johnsen scoring system.Results. The testicular tissue and serum levels of MDA, PC, and SOD activity were increased in the obesity group in comparison to the sham operated group (P<0.05). Weight loss and melatonin treatment ameliorated MDA, PC, and SOD levels in testicular tissue and serum significantly (P<0.05). There was no significant difference between groups in terms of mean Johnsen score (P=0.727).Conclusion. Experimentally created obesity caused oxidative stress and both melatonin and weight loss reduced oxidative stress parameters in rat testes.

Background: The role of minerals in preventing the generation of oxidative stress in obese individuals has been evaluated. Magnesium is an antioxidant nutrient and a cofactor of enzymes involved in the cell membrane stabilization, attenuating the effects of oxidative stress. Objective: To evaluate the association between magnesium and concentrations of thiobarbituric acid reactive substances (TBARS) in patients with obesity and eutrophic women. Methods: A cross-sectional study was conducted with 73 women, divided into two groups: case group (patients with obesity, n=27) and control group (eutrophic women, n=46). Measurements of body mass index and waist circumference were performed. Dietary magnesium intake was assessed by the three-day food record using the NutWin software. Urinary magnesium concentration was measured by atomic absorption spectrophotometry method. Plasma concentrations of thiobarbituric acid reactive substances (TBARS) were also determined. Results: Mean values of dietary magnesium intake were 161.59 ± 60.04 and 158.73 ± 31.96 for patients with obesity and control group, respectively, with no significant difference between the groups studied (p >0.05). The value of urinary excretion of magnesium was lower than the reference values in both groups, with no significant difference between the groups studied (p >0.05). The plasma concentration of thiobarbituric acid reactive substances was significantly higher in patients with obesity compared to the control group (p <0.001). There was no correlation between levels of magnesium biomarkers and the concentration of TBARS (p >0.05). Conclusion: Patients with obesity showed a reduced dietary magnesium intake which seems to induce hypomagnesuria as a compensatory mechanism. The marker of oxidative stress evaluated in this study was not influenced by magnesium.

Abstract Background and Study Aims Thyroid-associated orbitopathy, the most common extrathyroidal manifestation of Graves’ disease, is an autoimmune inflammation of orbital soft tissue. We report the study assessing the effect of immunosuppressive treatment with methylprednisolone on selected antioxidant parameters in patients with Graves’ disease with active thyroid-associated orbitopathy. Patients and Methods Activity and serum levels of selected antioxidant parameters as well as lipid peroxidation products were determined in a group of 56 patients with active thyroid-associated orbitopathy at three time-points: at baseline, after the discontinuation of intravenous methylprednisolone treatment and at 3 months after the discontinuation of additional oral methylprednisolone treatment. A control group consisted of 20 healthy age- and sex-matched volunteers. Results We found an increased activity of superoxide dismutase and glutathione peroxidase and increased serum levels of uric acid, malondialdehyde and conjugated dienes, as well as a reduced activity of paraoxonase-1 and reduced serum vitamin C level in the study group at baseline. Systemic intravenous and oral methylprednisolone therapy led to normalization of activity and concentration of the most studied parameters. Conclusion Results of our study confirmed that oxidative stress is one of the factors involved in the pathogenesis of thyroid-associated orbitopathy and the methyloprednisolone treatment is effective in reducing both clinical symptoms and oxidative stress in patients with this disease.

Background: There is a growing interest in the correlation between antioxidants and periodontal disease. In this study, we aimed to investigate the effect of oxidative stress and the impact of two antioxidants, curcumin and rutin, respectively, in the etiopathology of experimentally induced periodontitis in diabetic rats. Methods: Fifty Wistar albino rats were randomly divided into five groups and were induced with diabetes mellitus and periodontitis: (1) (CONTROL)—control group, (2) (DPP)—experimentally induced diabetes mellitus and periodontitis, (3) (DPC)—experimentally induced diabetes mellitus and periodontitis treated with curcumin (C), (4) (DPR)—experimentally induced diabetes mellitus and periodontitis treated with rutin (R) and (5) (DPCR)—experimentally induced diabetes mellitus and periodontitis treated with C and R. We evaluated malondialdehyde (MDA) as a biomarker of oxidative stress and reduced glutathione (GSH), oxidized glutathione (GSSG), GSH/GSSG and catalase (CAT) as biomarkers of the antioxidant capacity in blood harvested from the animals we tested. The MDA levels and CAT activities were also evaluated in the gingival tissue. Results: The control group effect was statistically significantly different from any other groups, regardless of whether or not the treatment was applied. There was also a significant difference between the untreated group and the three treatment groups for variables MDA, GSH, GSSG, GSH/GSSG and CAT. There was no significant difference in the mean effect for the MDA, GSH, GSSG, GSH/GSSG and CAT variables in the treated groups of rats with curcumin, rutin and the combination of curcumin and rutin. Conclusions: The oral administration of curcumin and rutin, single or combined, could reduce the oxidative stress and enhance the antioxidant status in hyperglycemic periodontitis rats.

AbstractOur aim was to detect type 2 innate lymphoid cells (ILC2s)-related cytokines of infants with bronchiolitis by using Elisa, Liquidchip technology and RT-PCR and investigated its correlation with bronchiolitis. We recruited 26 infants with bronchiolitis and 20 healthy infants as control from Xiangya Hospital. Compared to the control group, the serum levels of interleukin-5 (IL-5) [41.99 (21.11) vs 25.70 (19.64)], IL-9 [27.04 (37.51) vs 8.30 (0.54)], IL-13 [184.05 (132.81) vs 121.75 (176.13)], IL-33 [83.70 (46.69) vs 11.23 (55.31)] and thymic stromal lymphopoietin (TSLP) [31.42 (5.41) vs 28.76 (2.56)] were significantly increased in infants with bronchiolitis (P < 0.05), while the level of IgE had no significant difference between the two groups [19.05 (14.15) vs 14.85 (20.2), P > 0.05]. The mRNA expression of IL-17RB (9.83 ± 0.35 vs 9.19 ± 0.58), TSLP (16.98 ± 2.12 vs 15.07 ± 2.25), retinoid acid receptor related orphan receptor α (7.18 ± 0.71 vs 5.46 ± 1.09) and trans-acting T-cell-specific transcription factor 3 (4.86 ± 0.66 vs 4.19 ± 0.90) were significantly increased in infants with bronchiolitis versus the control group (P < 0.05), while there was no statistical significance for suppression of tumorigenicity 2 (5.59 ± 0.68 vs 5.41 ± 0.87, P > 0.05). Our findings suggested that ILC2s possibly play a specific role in immunopathology of bronchiolitis.

AbstractPatients afflicted with melanoma show lower vitamin D serum levels (VDSL) than the healthy population. This hypothesis agrees with its well-known antiproliferative features. An observational study was carried out to collect VDSL in patients suffering from melanoma. Our aim was to identify a potential connection between low VDSL and the risk to incur melanoma. Furthermore, we studied the association between VDSL at the diagnosis of melanoma and other germane prognostic factors. The population held in regard was composed of 154 patients with a diagnosis of melanoma between 2016 and 2019. These patients were retrospectively collected from our follow-up storage. We compared VDSL to clinical and pathological parameters (age, sex, tumour location, Breslow’s depth, Clark’s level, histological subtype, ulceration, et aliqua). Moreover, we recruited a control group with negative melanoma history. Mean and median of VDSL were significantly lower in the melanoma group. Instead, we found a negative association between melanoma and VDSL > 30 ng/L (OR 0.11; p < 0.0001). No correlation between VDSL and both Breslow’s depth and Clark’s level was discovered, but the VDSL comparison between thin (depth ≤ 1 mm) and thick tumours (depth > 1 mm) revealed a statistically significant difference (21.1 ± 8.2 ng/L vs 17.8 ± 8.1; p = 0.01). Moreover, VDSL were significantly lower in melanomas with mitotic rate ≥ 1/mm2 (22.1 ± 8.3 ng/L; p < 0007). Nevertheless, no connection was found between VDSL and both ulceration and positive sentinel nodes (p = 0.76; p = 0.74). Besides, our study revealed no association between VDSL and histological subtype (p = 0.161). Lower VDSL correlate with thick and high mitotic rate tumours. Future prospective studies would investigate if appropriate upkeep of suitable VDSL can decrease the risk of primary and recurrent melanoma diagnosis.

Background: Aortic valve sclerosis (AVSc) is defined as the thickening and calcification of aortic valve cusps, in the absence of obstruction of ventricular outflow. AVSc is linked with a clear imbalance in some trace elements. Aims: The objective of this study was to investigate the relationship between AVSc and serum levels of iron (Fe), zinc (Zn), selenium (Se), and copper (Cu). Additionally, this research aimed to explore the clinical significance of human serum zinc, selenium, copper, and iron concentrations as a potential new biomarker for AVSc patients and to clarify the pathophysiological role in individuals at risk of developing AVSc. Patients and methods: The study included 40 subjects with AVSc (25% male and 75% female) who were compared with a healthy control group with the same gender ratio. AVSc was based on comprehensive echocardiographic assessments. Blood samples were taken and Zn and Cu concentrations were determined through the use of atomic absorption spectroscopy. Se was measured using an inductively coupled plasma mass spectrometry device and Fe was measured using a Beckman Coulter instrument. Results: There was a significant difference in the prevalence of diabetes, blood pressure levels, and body mass index between the patients and the healthy subjects ( p < 0.05). The differences between the serum Fe, Se, and Cu levels of the AVSc patients and the healthy subjects ( p > 0.05) were recorded. The serum Zn of AVSc patients when compared was significantly lower compared with that of the control group ( p < 0.01). Conclusion: Patients with AVSc had an imbalance in some of the trace elements in their blood. The patient group’s valves had higher serum Cu levels and lower serum Se, Zn, and Fe concentrations compared with the healthy group’s valves. In the valve patients as compared, AVSc had a high prevalence of obesity, hypertension, and diabetes.
