The Impact

This study aimed to determine the impact of sesame meal, selenium (Se), and vitamin E (VitE) on goats’ oxidative status. Thirty mid-lactation crossbred goats were divided into five homogeneous groups, and were fed 1 kg of alfalfa hay and 1.2 kg of concentrates daily. The control group (C) received a basal diet. In the concentrates of the treated groups, 10% of the soybean meal was replaced by sesame meal and no extra VitE or Se (SM), or an extra 60 mg of VitE (SME), or 0.1 mg organic Se (SMSe), or their combination (60 mg VitE and 0,1 mg organic Se/kg of concentrate (SMESe). In the plasma of the goats, the dietary treatments did not affect glutathione reductase, glutathione peroxidase, glutathione transferase, catalase, superoxide dismutase activities, malondialdehyde (MDA) content, or the total antioxidant capacity. A reduction and a trend for lower protein carbonyls content was found in goats fed SM (p = 0.03) and SME (p = 0.06) compared to SMESe. In the milk, the lactoperoxidase activity decreased with SMSe and SMESe. A numerical decrease in the total antioxidant capacity and an increase in the MDA content in the milk of the SMESe group compared with the other treated groups was found. In mid-lactation goats, SM improves the oxidative status of both the organism and the milk.

Abstract The perinatal period is critical to survival and performance of many organisms. In birds, rapid postnatal growth and sudden exposure to aerial oxygen around hatching markedly affect the chick redox status, with potentially negative consequences on physiology mediated by oxidative stress. In addition, telomere length (TL) undergoes reduction during birds’ early life, partly depending on oxidative status. However, relatively few studies have focused specifically on the changes in oxidative status and TL that occur immediately after hatching. In this study of the yellow-legged gull Larus michahellis, we found that chicks undergo a marked increase in plasma total antioxidant capacity and a marked decrease in the concentration of pro-oxidant molecules during the first days after hatching. In addition, TL in erythrocytes decreased by 1 standard deviation over the 4 days post-hatching. Body mass and tarsus length covaried with total antioxidant capacity and concentration of pro-oxidants in a complex way, that partly depended on sex and laying order, suggesting that oxidative status can affect growth. Moreover, TL positively covaried with the concentration of pro-oxidant molecules, possibly because retention of high concentrations of pro-oxidant molecules results from mechanisms of prevention of their negative effects, including reduction in TL. Thus, this study shows that chicks undergo marked variation in oxidative status, which predicts growth and subsequent TL, prompting for more studies of the perinatal changes in the critical post-hatching stages.

Abstract Background Redox imbalance is involved in several aspects of inflammatory bowel disease (IBD). The OxIBDiet (NCT04513015) is a multicentre, 2-phases project involving IBD children and adults with the following aims: 1. To evaluate oxidative status of IBD subjects. 2. To estimate the effects of an antioxidant diet in IBD patients. Preliminary results are shown in this abstract. Methods The total antioxidant capacity, lipid peroxidation and the degree of protein oxidation were measured respectively through the ferric reducing ability of plasma (FRAP, µmol/equivalent FeSO4), serum levels of the thiobarbituric acid reactive substances (TBARs, µmol MDA) and advanced Oxidation Protein Products (AOPP, µmol/g protein). Reactive oxygen species (ROS, Arbitrary Units) and activities (nmol/min/mg of protein) of the main antioxidant enzymes, superoxide dismutase (SOD), glutathione peroxidase (GPX), glutathione reductase (GR), glutathione S-Transferase (GST) and catalases (CAT) were evaluated in PMNs cells. Oxidative stress markers were correlated with demographic variables and clinical parameters. Results Fifteen adults (mean age: 36.2 ±11.4 years, 47% female, 67% in remission) and thirty five children (mean age: 14.13 ±2.2 years, 60% female, 65% in remission) with IBD have been enrolled so far. FRAP was significantly reduced in IBD children compared to healthy controls (median values: 212.1 vs. 248.3, p=0.0001) and to IBD adults (median value: 281, p<0.001), while no difference was observed between adults with IBD and the control group (p= 0.1). ROS levels did not differ in IBD children compared to adults and controls. The activity of GPX and CAT enzymes was increased in children with IBD in comparison to controls (p:0.02 and 0.001, respectively) while the activity of the other enzymes (GST, GR and SOD) and levels of lipid peroxidation and protein oxidation was not different between the 2 groups. Overall in the IBD group (children plus adults) FRAP was positively correlated with age (r=0.40, p=0.006), male gender (r=0.33, p=0.03) and use of biologics (r=0.47, p=0.001) and inversely correlated to disease activity based on clinical scores (r= -0.38, p=0.009). No correlation was found between FRAP and serum C-reactive protein or calprotectin levels. Conclusion The total antioxidant capacity (FRAP) is significantly impaired in IBD children respect to IBD adults and to healthy controls, thus suggesting an early involvement of oxidative stress in IBD pathogenesis. Moreover, the activity of the main antioxidant enzymes (GPx and CAT) in IBD children is increased, as a possible compensation for redox imbalance. Final results will clarify the involvement of antioxidant cascade in IBD pathogenesis and in therapeutic approach.

Objective: To compare paraoxonase activity and changes in oxidative status in asthmatic children and healthy children by determining serum paraoxonase activity and total oxidative status, total antioxidant capacity and lipid hydroperoxidation. Methods: Forty two asthmatic children were compared with 32 healthy children of similar age and sex. To evaluate the paraoxonase and oxidative status, total antioxidant capacity and lipid hydroperoxidation were examined. Serum paraoxonase activity was evaluated by measuring the rate of paraoxon hydrolosis. Oxidative status was evaluated by the method developed by Erel. Lipid hydroperoxide was measured by an iodometric method. Results: In comparison with the healthy control group, the paraoxonase activity of the asthmatic children was found to be low (163.7 ± 73.0 (U/L) and 349.2 ± 153.9 (U/L), P = 0.002) and total oxidant status (9.0 ± 3.5 ?mol H2O2 Eq/L and 13.4 ± 7.0 ?mol H2O2 Eq/L, P =0.002), total antioxidant capacity (5.5 ± 2.5 µmol Trolox Eq/L and 1.0 ± 0.6 µmol Trolox Eq/L, P < 0.001), and lipid hydroperoxidation values (9.9 ± 3.4 ?mol H2O2 Eq/L and 4.4 ± 1.5 ?mol H2O2 Eq/L, P < 0.001) were found to be high. The high density lipoprotein (HDL) concentration of the asthmatic children was lower than that in the control group (40.1 ± 9.2 mg/dl and 54.5 ± 15.9 mg/dl, P < 0.001) Conclusion: In asthmatic children, when total oxidant status, total antioxidant capacity and lipid hydroperoxidation levels increase, paraoxonase activity decreased.

Background: The target of the reduced fecundity with aging is the oocyte. The follicular fluid and its components are strongly linked with the environment of the maturing oocyte. The aim of the present study was to evaluate CoQ10 bioavailability in follicular fluids after oral supplementation and its possible implication in oocyte maturation. Methods: Fifteen female partners of infertile couples, aged 31–46, undergoing IVF-ET and taking 200 mg/day oral CoQ10 were compared to unsupplemented patients. CoQ10 content, its oxidative status and total antioxidant capacity were evaluated also in relation to oocyte maturation indexes. Results: CoQ10 supplementation produced a significant increase in follicular content and a significant improvement of its oxidative status. Follicular fluid total antioxidant capacity highlighted a significant decrease in patients supplemented with CoQ10, specially in women >35 years. CoQ10 supplementation was associated with a significant decrease in total antioxidant capacity of fluid from follicles containing mature oocyte, moreover CoQ10 oxidative status was also significantly reduced but in follicles containing immature oocyte. Conclusions: Our observation leads to the hypothesis that the oral supplementation of CoQ10 may improve follicular fluid oxidative metabolism and oocyte quality, specially in over 35-year-old women.
