Abstract
We evaluated the efficacy of mozuku fucoidan supplementation to alternative dietary proteins used in fish meal (FM) replacement to enhance growth, immunity, and stress resistance of Pagrus major. Seven isonitrogenous (45% protein) experimental diets were formulated where diet 1 (D1) was FM-based control diet. Diets 2 to 7 were formulated by replacing 25, 50, and 75% of FM protein with soy protein isolate (SPI) protein, and each replacement level was supplemented without or with fucoidan at 0.4% for diet groups D2 (FM25), D3 (FM25Fu), D4 (FM50), D5 (FM50Fu), D6 (FM75), and D7(FM75Fu), respectively. Each diet was randomly allocated to triplicate groups of fish (4.1 g) for 56 days. Significantly higher weight gain and specific growth rate were observed in fish fed FM50Fu diet group, and it was not differed (P > 0.05) with fish fed FM25Fu diet group. FM-based control diet showed intermediate value, and it was not differed (P > 0.05) with or without fucoidan-supplemented ≤ 50% FM replacement groups and FM75Fu diet group. Significantly lower growth performances were observed in FM75 diet group. At each replacement level, fucoidan-supplemented groups showed nonsignificant improvement of feed utilization performances. Fish fed fucoidan-supplemented diets showed best condition of oxidative and freshwater stress resistance. Lysozyme activity, NBT, and peroxidase activity showed higher (P > 0.05) values in fucoidan-supplemented groups compared with the non-supplemented groups. Catalase activity was significantly lower in FM75Fu diet group. Catalase activity is significantly influenced by the interaction effects of fucoidan and FM replacement level. In conclusion, fucoidan supplementation could increase the efficiency of utilizing SPI (≥ 75%) without any adverse effects on red sea bream performance.

[PMID: 28577647 PMCID: PMC5457465 DOI: 10.1016/j.bjhh.2017.01.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2016] [Revised: 12/13/2016] [Accepted: 01/05/2017] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Oxidative stress may aggravate symptoms of hemolytic anemias such as beta-thalassemia. FoxO3 activation results in resistance to oxidative stress in fibroblasts and neuronal cell cultures. OBJECTIVE The purpose of this research was to study FoxO3 gene expression and oxidative status in beta-thalassemia minor individuals. METHODS Sixty-three subjects (42 apparently healthy individuals and 21 with beta-thalassemia minor) were analyzed at the Universidad Nacional de Tucumán, Argentina, between September 2013 and June 2014. A complete blood count, hemoglobin electrophoresis in alkaline pH and hemoglobin A2 levels were quantified. Moreover, thiobarbituric acid reactive species, erythrocyte catalase activity and iron status were evaluated. Beta-thalassemia mutations were determined by real-time polymerase chain reaction. FoxO3 gene expression was investigated by real-time reverse transcription-polymerase chain reaction using mononuclear cells from peripheral blood. RESULTS Subjects were grouped as children (≤12 years), and adult women and men. The analysis of erythrocyte catalase activity/hemoglobin ratio revealed a significant difference (p-value <0.05) between healthy and beta-thalassemia minor adults, but no significant difference was observed in the thiobarbituric acid reactive species levels and FoxO3 gene expression (p-value >0.05). Thiobarbituric acid reactive species and the erythrocyte catalase activity/hemoglobin ratio were not significantly different on comparing the type of beta-thalassemia mutation (β0 or β+) present in carriers. CONCLUSIONS The lack of systemic oxidative imbalance demonstrated by thiobarbituric acid reactive species is correlated to the observation of normal FoxO3 gene expression in mononuclear cells of peripheral blood. However, an imbalanced antioxidant state was shown by the erythrocyte catalase activity/hemoglobin ratio in beta-thalassemia minor carriers. It would be necessary to study FoxO3 gene expression in reticulocytes to elucidate the role of FoxO3 in this pathology.

Abstract
The study was designed to assess the effect of different strawberry extracts on glucose levels, lipid profiles, and oxidative stress in nicotinamide-streptozotocin (NIC-STZ) induced diabetic rats. The associated changes were evaluated through biochemical, molecular, and histological assays. Diabetes was induced by intraperitoneal injection of STZ to albino Wistar rats after treatment with nicotinamide. Aqueous, hydroalcoholic, and alcoholic strawberry extracts were administrated orally to diabetic rats. Treatment of strawberry extracts improved lipid profile, liver function, and serum creatinine and led to a significant increase in antioxidant status in diabetic rats. Real-time PCR expression analysis of genes from the liver of animals treated with strawberry extracts exhibited downregulation of several fatty acid synthesis genes, transcription factors, such as Sterol regulatory Element Binding Transcription factor (SREBP) and Nuclear Factor-κβ (NF-κβ), and inflammatory markers, like Interleukin 6 (IL6) and Tumor Necrosis Factor-α (TNF-α). Strawberry extracts also upregulated liver Peroxisome Proliferator Activated Receptor-γ (PPAR-γ). Histological examination confirmed the nephroprotective and β-cell regeneration/protection effects of strawberry extracts. The present study demonstrates several beneficial effects of strawberry extracts along with its probable mechanism of action.

Abstract
The present study explored the dietary administration effects of guanosine monophosphate (GMP) on growth, digestibility, innate immune responses and stress resistance of juvenile red sea bream, Pagrus major. A semi-purified basal diet supplemented with 0% (Control), 0.1% (GMP-0.1), 0.2% (GMP-0.2), 0.4% (GMP-0.4) and 0.8% (GMP-0.8) purified GMP to formulate five experimental diets. Each diet was randomly allocated to triplicate groups of fish (mean initial weight 3.4 g) for 56 days. The obtained results clearly indicated that, growth performance of red sea bream enhanced by dietary GMP supplementation compared to control and significantly higher final weight was found in fish fed diet group GMP-0.4. Specific growth rate (SGR) and percent weight gain (%WG) also significantly higher in diet group GMP-0.4 in compared to control and it was not differed (P > 0.05) with diet group GMP-0.8. Feed intake significantly increased with the supplementation of GMP. Feed conversion efficiency (FCE) and protein efficiency ratio (PER) also improved (P < 0.05) when fish fed the diets containing GMP and diet group GMP-0.4 showed the significantly higher value in compared to control. The Apparent digestibility coefficients (dry matter, protein and lipid) also improved by GMP supplementation and the significantly higher protein digestibility was observed in fish fed diet groups GMP-0.2, GMP-0.4 and GMP-0.8. Among the measured non specific immune parameters peroxidase activity (PA), respiratory burst activity (NBT), Bactericidal activity (BA) were significantly affected by dietary supplementation and highest value obtained in diet group GMP-0.4. Total serum protein, lysozyme activity (LA), and agglutination antibody titer also increased (P > 0.05) by GMP supplementation. In contrast, catalase activity decreased with GMP supplementation. In terms of oxidative stress GMP-0.2 showed best condition with low oxidative stress and high antioxidant level. Moreover, the fish fed GMP supplemented diets had better improvement (P < 0.05) in body protein contents, hepatosomatic index, hematocrit content and glutamyl oxaloacetic transaminase (GOT) and glutamic-pyruvate transaminase (GPT) level than the control group. Supplementation also improved (P < 0.05) freshwater stress resistances. Quadratic regression analysis of WG and LA revealed that, the optimal levels of dietary GMP were 0.45 and 0.48%, respectively, for juvenile red sea bream, which is also in line with the most of the growth performance and health parameters of the fish.

Abstract
Our study explored the dietary effects of adenosine monophosphate (AMP) to enhance growth, digestibility, innate immune responses and stress resistance of juvenile red sea bream. A semi-purified basal diet supplemented with 0% (Control), 0.1% (AMP-0.1), 0.2% (AMP-0.2), 0.4% (AMP-0.4) and 0.8% (AMP-0.8) purified AMP to formulate five experimental diets. Each diet was randomly allocated to triplicate groups of fish (mean initial weight 3.4 g) for 56 days. The results indicated that dietary AMP supplements tended to improve growth performances. One of the best ones was found in diet group AMP-0.2, followed by diet groups AMP-0.1, AMP-0.4 and AMP-0.8. The Apparent digestibility coefficients (dry matter, protein and lipid) also improved by AMP supplementation and the significantly highest dry matter digestibility was observed in diet group AMP-0.2. Fish fed diet groups AMP-0.2 and AMP-0.4 had significantly higher peroxidase and bactericidal activities than fish fed the control diet. Nitro-blue-tetrazolium (NBT) activity was found to be significantly (P < 0.05) greater in fish fed diet groups AMP-0.4 and AMP-0.8. Total serum protein, lysozyme activity and agglutination antibody titer were also increased (P > 0.05) by dietary supplementation. In contrast, catalase activity decreased with AMP supplementation. Moreover, the fish fed AMP supplemented diets had better improvement (P < 0.05) in body lipid contents, condition factor, hematocrit content and glutamyl oxaloacetic transaminase (GOT) level than the control group. Supplementation also improved both freshwater and oxidative stress resistances. Interestingly, the fish fed diet groups AMP-0.2 and AMP-0.4 showed the least oxidative stress condition. Finally it is concluded that, dietary AMP supplementation enhanced the growth, digestibility, immune response and stress resistance of red sea bream. The regression analysis revealed that a dietary AMP supplementation between 0.2 and 0.4% supported weight gain and lysozyme activity as a marker of immune functions for red sea bream, which is also inline with the most of the growth and health performance parameters of fish under present experimental conditions.

Abstract
Acellular hemoglobins developed as oxygen bridging agents with volume expanding properties ("blood substitutes") are prone to autoxidation and oxidant-mediated structural changes in circulation. In the presence of hydrogen peroxide and either ascorbate or urate we show that ferric hemoglobin functions as a true enzymatic peroxidase. The activity saturates with both substrates and is linearly dependent on protein concentration. The activity is enhanced at low pH with a pKa of 4.7, consistent with protonation of the ferryl species (Fe(IV)-OH) as the active intermediate. To test whether these redox reactions define its behaviour in vivo we exchanged transfused guinea pigs with 50% polymerized bovine Hb (PolyHbBv) and monitored plasma levels of endogenous ascorbate and urate. Immediately after transfusion, met PolyHbBv levels increased up to 30% of total Hb and remained at this level during the first 24 h post transfusion. Plasma ascorbate decreased by 50% whereas urate levels remained unchanged after transfusion. A simple kinetic model, assuming that ascorbate was a more active ferric heme reductase and peroxidase substrate than urate, was consistent with the in vivo data. The present finding confirms the primary and secondary roles of ascorbate and urate respectively in maintaining the oxidative stability of infused Hb.

Abstract
OBJECTIVES Develop fully automated assay of antioxidant catalatic activity of catalase. DESIGN AND METHODS The assay is based on standard, clinical chemistry automated analyzer methods for measuring hydrogen peroxide by using the Trinder reagent. Catalase competes with 324 U/L horseradish peroxidase (type XII) and Trinder reagent for hydrogen peroxide produced by 46 U/L uricase action on urate. Unit activity is defined as 50% inhibition of maximal color development. RESULTS Within-run coefficients of variation (cv) were 2% for standards and samples, whereas between-run cv was 3.1% for standards and 7.3% for samples. Dilutional parallelism and linearity were demonstrated for 8-fold dilutions of samples over the range 0.1 to 1.1 U/mL. Recovery of added catalase was complete. Samples are stable to freezing and storage for 1 week at -80 degrees C. Activities (units/mL) ranged from 0.29 to 0.41 in human and canine plasma, and for erythrocytes from 48 to 70 in man, 17 to 19 in dogs, and 60 to 89 in rats. Rat liver activity (units/g wet weight) was age-dependent and ranged from 17 to 24 at 2 months, and from 19 to 37 at 6 months. CONCLUSION The first, fully automated assay for the measurement of catalatic activity of catalase in plasma, erythrocytes, and liver is demonstrated for multiple species. The assay is simple, precise, relatively inexpensive, and rapid.

Abstract
Two Hungarian acatalasemic and eight hypocatalasemic patients revealed normal erythropoesis. Contrary to their decreased defence system against the toxic hydrogen peroxide, the biochemical tests (serum catalase, serum hemoglobin, serum lactate dehydrogenase (LDH) ratio of LDH1 and LDH2 isoenzymes and serum haptoglobin) excluded hemolysis. The normal activity of glutathione peroxidase and the decreased catalase activity could prevent the lysis of the erythrocytes. In the presence of extremely high levels of hydrogen peroxide acute hemolysis may not be excluded; therefore, follow-up of these patients is required.

Abstract
A rapid, cost-efficient, spectrophotometric assay for serum catalase activity was developed. It was a combination of optimized enzymatic conditions and the spectrophotometric assay of hydrogen peroxide based on formation of its stable complex with ammonium molybdate. Lipemic and icteric sera increased the absorbance without influencing the catalase assay. Due to the high catalase activity in erythrocytes artificial hemolysis increased serum catalase activity. The imprecision of the method was CV less than 5.8% within run as well and day-to-day. The catalase assay performed using polarographic and spectrophotometric determination of hydrogen peroxide yielded a good correlation (r = 0.9602, b = 1.011, a = -0.648, n = 440). In 742 healthy individuals the mean and SD values of serum catalase were 50.5 +/- 18.1 kU/l with 17.7% higher activity in males than in females. Between 14-60 yr the serum catalase increased with age.

Abstract
Serum catalase activity was examined in 96 patients with the oedematous form and in 15 patients with the necrotic form of acute pancreatitis. Total catalase release into plasma was estimated to be 2,140 +/- 947 kU and 4,764 +/- 1,505 kU, respectively. The g equivalents of pancreas were 163 +/- 72 g and 362 +/- 133 g, being 2.03-fold and 4.52-fold higher than the whole mass of pancreas indicating the nonpancreatic origin of the total increase of serum catalase. In both types of acute pancreatitis serum haemoglobin, haematin, haptoglobin and LDH values supported the presence of haemolysis. The volumes of blood were 22.6 +/- 10.1 ml and 50.4 +/- 15.9 ml which are only 0.41% and 0.91% of the total blood volume. Taking these findings into account, in acute pancreatitis the major part of increase of serum catalase can be explained by its release from the erythrocytes.

Abstract
Measurement of the oxygen metabolite hydrogen peroxide (H2O2) in biological fluids such as plasma could be of interest because it might indicate participation of toxic oxygen species in tissue injury. Recently several reports claimed to measure H2O2 using spectrophotometric and high pressure liquid chromatographic (HPLC) techniques that utilize oxidation of a substrate to a product by a peroxidase. In such a system it is crucial to perform two control experiments to verify whether the measured substance is H2O2. The specificity of the assay for H2O2 should be checked with catalase, and the degradation of H2O2 or inhibition of the assay system by the sample should be checked by determining the recovery of exogenously added H2O2. We performed both types of controls for HPLC and spectrophotometric determinations of H2O2 in plasma and blood. Our results indicate that contrary to previous reports in the literature the measured substance(s) in plasma or blood is not H2O2. Moreover, quantitative measurements of H2O2 in plasma or blood by HPLC was unreliable due to the irreversible binding of H2O2 to the column surface.
