Abstract
The purpose of this study is to determine the chemical compositions, anti-nutrient compositions, antioxidant properties, and phenolic profile of the leaves of orange fleshed sweet potato varieties [King J (UMUSPO1) and mother's delight (UMUSPO2)] in Nigeria and their suitabilities in soup preparation. Freshly harvested leaves of the two varieties of orange fleshed sweet potato were sorted, cleaned, dried, and milled into powder. The dried leaves were assessed for their chemical compositions viz proximate and mineral compositions, the anti-nutrient compositions, antioxidant properties, and phenolic profile. The overall acceptability of the leafy vegetables in the preparation of a local soup (Edikang Ikong) was evaluated. The ash, fat, and protein contents of UMUSPO1 leaves were higher than UMUSPO2, similarly UMUSPO1 leaves had higher mineral contents. Phytate and saponin contents were higher in UMUSPO2, however, the calculated molar ratios were below critical levels. The 2,2-diphenyl-1-picrylhydrazyl hydrate radical scavenging activity and ferric reducing antioxidant power assay were higher in UMUSPO1. Seven phenolic compounds were identified and quantified in both leaves with gallic acid being the most abundant. The taste of soup prepared with UMUSPO2 was rated higher, however, no significant difference was observed in the overall acceptability of the soups. The two leaves are good sources of nutritional antioxidants and can be suitable for the management of some disease conditions linked to oxidative stress.

Abstract
Wheat bread was enriched with 6%, 10% and 15% dried and milled grape pomace flour from two grape cultivars: ‘Merlot’ and ‘Zelen’. Rheological, textural, sensory and antioxidant properties of the enriched dough and bread were evaluated, and compared to control samples. Grape cultivar had significant impact on the rheological characteristics of the dough, and on the sensory and antioxidant properties of the final bread. Development time and dough stability were longer when ‘Merlot’ grape pomace flour was added compared to ‘Zelen’ grape pomace flour and the control. Grape pomace flour addition affected bread volume, firmness, crumb and crust colour, and odour and taste intensity. Moreover, grape pomace flour addition resulted in a stickier and less springy crumb texture, and some negative sensorial properties, such as increased intensity of aftertaste and sand feeling in the mouth. The phenolic content and antioxidant activity of bread were positively correlated with grape pomace flour addition ( r = 0.987, p = 0.01 and r = 0.941, p = 0.01 between phenolic content and ferric reducing antioxidant power and phenolic content and 2,2-diphenyl-1-picrylhydrazyl, respectively). The highest total phenolic contents were 5.92 mg gallic acid equivalents (GAE)/g dw for ‘Merlot’ and 3.65 mg gallic acid equivalents /g dw for ‘Zelen’, which were seen for the bread prepared with the highest grape pomace flour addition (15%). The highest antioxidant activity determined by the 2,2-diphenyl-1-picrylhydrazyl and ferric reducing antioxidant power assays were seen for the bread prepared with the highest ‘Merlot’ grape pomace flour addition (15%). Dough characteristic and sensory profile are strongly influenced by cultivar of grape pomace flour. Based on results of sensory profiling, the variety ‘Zelen’ is suggested for use.

Deregulation of apoplastic polyamine oxidase affects development and salt response of tobacco plants. JOURNAL OF PLANT PHYSIOLOGY 2017; 211:1-12. [PMID: 28135604 DOI: 10.1016/j.jplph.2016.12.012] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/03/2016] [Revised: 12/15/2016] [Accepted: 12/19/2016] [Indexed: 05/02/2023]
Abstract
Polyamine (PA) homeostasis is associated with plant development, growth and responses to biotic/abiotic stresses. Apoplastic PA oxidase (PAO) catalyzes the oxidation of PAs contributing to cellular homeostasis of reactive oxygen species (ROS) and PAs. In tobacco, PAs decrease with plant age, while apoplastic PAO activity increases. Our previous results with young transgenic tobacco plants with enhanced/reduced apoplastic PAO activity (S-ZmPAO/AS-ZmPAO, respectively) established the importance of apoplastic PAO in controlling tolerance to short-term salt stress. However, it remains unclear if the apoplastic PAO pathway is important for salt tolerance at later stages of plant development. In this work, we examined whether apoplastic PAO controls also plant development and tolerance of adult plants during long-term salt stress. The AS-ZmPAO plants contained higher Ca2+ during salt stress, showing also reduced chlorophyll content index (CCI), leaf area and biomass but taller phenotype compared to the wild-type plants during salt. On the contrary, the S-ZmPAO had more leaves with slightly greater size compared to the AS-ZmPAO and higher antioxidant genes/enzyme activities. Accumulation of proline in the roots was evident at prolonged stress and correlated negatively with PAO deregulation as did the transcripts of genes mediating ethylene biosynthesis. In contrast to the strong effect of apoplastic PAO to salt tolerance in young plants described previously, the effect it exerts at later stages of development is rather moderate. However, the different phenotypes observed in plants deregulating PAO reinforce the view that apoplastic PAO exerts multifaceted roles on plant growth and stress responses. Our data suggest that deregulation of the apoplastic PAO can be further examined as a potential approach to breed plants with enhanced/reduced tolerance to abiotic stress with minimal associated trade-offs.

Abstract
We investigated the antioxidative activity of LX519290, a derivative of l-allo threonine, in vitro and in vivo. To evaluate the antioxidative activity of LX519290, we performed several in vitro assays (2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis-(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) radical-scavenging assays, a ferric reducing antioxidant power assay, cupric-reducing antioxidant capacity, and oxygen radical absorbance capacity assay) and evaluated inhibition against the generation of nitric oxide (NO) and reactive oxygen species (ROS) in murine macrophage (RAW264.7) cells. The results showed that LX519290 possessed very strong radical scavenging activity and reducing power, and inhibited NO and ROS generation in a dose-dependent manner without showing any cytotoxicity. LX519290 treatment also increased the total thiol content and glutathione S-transferases (GST) activities in RAW264.7 cells. Finally, we also determined whether LX519290 affects the mRNA levels of antioxidant enzymes in vitro and in vivo. The expression of superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) were markedly higher in the sample-treated group than in the oxidative stress group. LX519290 treatment also increased the transcriptional and translational activities of NF-E2-related factor-2 (Nrf-2) with corresponding increases in the transcriptional and translational activities of haeme oxygenase-1 (HO-1). Collectively, the data demonstrated that LX519290 has potent antioxidative activity, decreases NO and ROS generation, increases total thiol content and GST activities in RAW264.7 cells, and increases the transcriptional and translational levels of antioxidant enzymes in vitro and in vivo.

Abstract
Polyamines (PAs) are nitrogenous molecules that are indispensable for cell viability and with an agreed-on role in the modulation of stress responses. Tobacco plants with downregulated SAMDC (AS-SAMDC) exhibit reduced PAs synthesis but normal levels of PA catabolism. We used AS-SAMDC to increase our understanding on the role of PAs in stress responses. Surprisingly, at control conditions AS-SAMDC plants showed increased biomass and altered developmental characteristics, such as increased height and leaf number. On the contrary, during salt stress AS-SAMDC plants showed reduced vigor when compared to the WT. During salt stress, the AS-SAMDC plants although showing compensatory readjustments of the antioxidant machinery and of photosynthetic apparatus, they failed to sustain their vigor. AS-SAMDC sensitivity was accompanied by inability to effectively control H2O2 levels and concentrations of monovalent and divalent cations. In accordance with these findings, we suggest that PAs may regulate the trade-off between growth and tolerance responses.

Abstract
SCOPE An increased intake of Zinc (Zn) may reduce the risk of degenerative diseases but may prove to be toxic if taken in excess. This study aimed to investigate whether zinc carnosine supplement can improve Zn status, genome stability events, and Zn transporter gene expression in an elderly (65-85 years) South Australian cohort with low plasma Zn levels. METHODS AND RESULTS A 12-week placebo-controlled intervention trial was performed with 84 volunteers completing the study, (placebo, n = 42) and (Zn group, n = 42). Plasma Zn was significantly increased (p < 0.05) by 5.69% in the Zn supplemented group after 12 weeks. A significant (p < 0.05) decrease in the micronucleus frequency (-24.18%) was observed for the Zn supplemented cohort relative to baseline compared to the placebo group. Reductions of -7.09% for tail moment and -8.76% for tail intensity were observed for the Zn group (relative to baseline) (p < 0.05). Telomere base damage was found to be also significantly decreased in the Zn group (p < 0.05). Both MT1A and ZIP1 expression showed a significant increase in the Zn supplemented group (p < 0.05). CONCLUSION Zn supplementation may have a beneficial effect in an elderly population with low Zn levels by improving Zn status, antioxidant profile, and lowering DNA damage.

Abstract
AIM In the present study, the anti-inflammatory and antioxidant activities of the methanol extract of Ruta graveolens leaves (RG-M) were evaluated using various in vivo and in vitro models. METHOD For anti-inflammatory activity, RG-M was administered by the oral route (p.o.) in a carrageenan-induced paw edema model, and by the intraperitoneal route (i.p.) in an exudative inflammation model. In vitro inhibition of cyclooxygenase and lipoxygenase enzymes was evaluated. In vitro antioxidant activity was also examined. Endogenous antioxidant status was further evaluated by ferric reducing ability of plasma model. RESULTS RG-M showed maximum inhibition of carrageenan-induced edema (100 mg·kg⁻¹ - 33.36%; 200 mg·kg⁻¹ - 45.32% and 400 mg·kg⁻¹ - 56.28%). In the exudative inflammation model, a significant reduction in leukocyte migration (200 mg·kg⁻¹ - 54.75% and 400 mg·kg⁻¹ - 77.97%) and protein exudation (200 mg·kg⁻¹ - 31.14% and 400 mg·kg⁻¹ - 49.91%) were observed. RG-M also exhibited inhibition of COX-1 (IC50 182.27 μg·mL⁻¹) and COX-2 (IC50 190.16 μg·mL⁻¹) as well as 5-LOX (IC50 215.71 μg·mL⁻¹). Antioxidant activity was significant with improved endogenous antioxidant status. CONCLUSION The results demonstrated the anti-inflammatory and antioxidant activity of RG-M with potent inhibitory effects on the arachidonic acid pathways.

Abstract
The powder samples and methanol extract of 11 medicinal plants were subjected to analysis of proximate composition and measurement of antioxidant activity. Different parameters studied include phenolic contents, moisture, ash, crude fiber, fats and waxes. The assays employed were ferric reducing antioxidant power, trolox equivalent antioxidant capacity and scavenging effect on the 1,1-diphenyl-2-picrylhydrazyl free radical. Results obtained indicate that the antioxidant potential varied significantly from plant to plant. The total phenolic contents were determined spectrophotometrically using Folin-Ciocalteu reagent. Significant correlation is observed between ferric reducing antioxidant power and phenolic contents (R(2) = 0.96). These findings show that the polyphenolic constituents in the extracts are responsible for free radical scavenging capacity.

Abstract
The present study reports a comparison of the antioxidant properties and phenolic profile of the most consumed species as fresh cultivated mushrooms and their mycelia produced in vitro: Agaricus bisporus (white and brown), Pleurotus ostreatus (oyster), Pleurotus eryngii (king oyster) and Lentinula edodes (shiitake). The antioxidant activity was evaluated through reducing power (Folin-Ciocalteu and Ferricyanide/Prussian blue assays), free radical scavenging activity (DPPH assay) and lipid peroxidation inhibition (β-carotene/linoleate and TBARS assays). The analysis of phenolic compounds was performed by HPLC/PAD. The mushroom species with the highest antioxidant potential was Agaricus bispous (brown). However, concerning to the species obtained in vitro, it was L. edodes that demonstrate the highest reducing power. Generally, in vivo samples revealed higher antioxidant properties than their mycelia obtained by in vitro techniques. About the phenolic compounds researched, they were detected both in mushrooms and mycelia without any particular abundance. Results showed that there is no correlation between the studied commercial mushrooms and the corresponding mycelia obtained in vitro. Nevertheless, this study contributes to the rise of data relatively to the species consumed as fresh mushrooms and the possibility of their in vitro production as a source of bioactive compounds.

Abstract
Prunella vulgaris L. (PV, Labiatae) is known as a self-heal herb. The different extracts of dried spikes were studied for the best antioxidant active compounds. The 60% ethanol extract (P-60) showed strong antioxidant activity based on the results of 2,2'-azino-di(3-ethylbenzthiazoline-6-sulfonic acid (ABTS˙+), 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assay methods. High performance liquid chromatography (HPLC) and LC/MS analysis showed that the main active compounds in P-60 were phenols, such as caffeic acid, rosmarinic acid, rutin and quercetin. Total phenols were highly correlated with the antioxidant activity (R2=0.9988 in ABTS˙+; 0.6284 in DPPH and 0.9673 FRAP tests). P-60 could inhibit significantly the tumor growth in C57BL/6 mice. It can also been showed that increased superoxide dismutase (SOD) activity and decreased malondialdehyde (MDA) content in serum of tumor-bearing mice. These results suggested that P-60 extract had high antioxidant activity in vitro and in vivo and total phenols played an important role in antioxidant activity for inhibition of tumor growth.

Abstract
The aim of this study is to evaluate the individual differences in radiosensitivity of lineage-committed myeloid hematopoietic progenitors, colony-forming cells (CFC), detected in steady-state human peripheral blood (PB). Mononuclear cells were prepared from the buffy-coat of 30 individuals PB, and were assayed for CFC by semi-solid culture supplemented with cytokines. X irradiation was performed in the range of 0.5-4 Gy at a dose rate of about 80 cGy/min. The mean number of hematopoietic progenitor cells is 5866 alpha 3408 in 1 ml of buffy-coat, suggesting that the erythroid progenitor cells are the major population. The total CFC radiosensitivity parameter D(0) and n value are 1.18 alpha 0.24 and 1.89 alpha 0.98, respectively. Using a linear regression analysis, a statistically significant correlation is observed between the D(0) value and the surviving fraction at 4 Gy (r = 0.611 p < 0.001). Furthermore, we evaluate the relationship between individual radiosensitivity and the level of antioxidants, plasma uric acid, plasma bilirubin, and intracellular glutathione. No statistically significant correlations are observed, however, between the D(0) parameter and the level of antioxidants, plasma uric acid, plasma bilirubin, and intracellular glutathione. The present study demonstrates that there are large individual differences in the radiosensitivity of hematopoietic progenitor cells as detected in steady-state human PB. These differences demonstrate almost no correlation with plasma or intracellular antioxidants. The prediction of individual differences in radiosensitivity of CFC can only be measured by 4 Gy irradiation.

Abstract
The aetiology of varicocele is multifactorial although hormonal imbalance and oxidative stress play a key role in the progression of illness. No conclusive evidence has been presented previously, describing the changes in these two factors and the evolution of patients after varicocelectomy. Semen characteristics and hormonal profile were analysed in 36 infertile men with unilateral left varicocele and 33 age-paired controls (proved to be fertile men), after careful inclusion/exclusion selection criteria. Liposoluble and hydrosoluble antioxidants, oligoelements and enzyme activities of the antioxidant defence system were also determined in plasma and erythrocyte from antecubital and spermatic veins, and in spermatozoa. Data were compared between groups at different times before and after varicocelectomy. Decreased levels of liposoluble and hydrosoluble antioxidants and increased activities of the antioxidant defence system enzymes were observed in patients compared with controls. Varicocelectomy normalized this condition at different post-surgical times. Levels of Zn and Se in seminal plasma, protein carbonyls and fragmented DNA remained elevated up to 1 month after surgery. Luteinizing and follicle stimulating hormone concentrations exhibited a biphasic behaviour while testosterone was diminished in patients but normalized soon after varicocelectomy. The results clearly demonstrate the link between the antioxidant defence system, hormonal status and semen characteristics along the post-varicocelectomy period. We suggest that oxidative biomarkers may be appropriate in controlling the evolution of post-varicocelectomy patients, and antioxidant supplementation may improve the clinical condition of infertile men with varicocele.

Abstract
In previous studies, we showed that docosahexaenoic acid (DHA) ingestion enhanced the susceptibility of rat liver and kidney to lipid peroxidation, but did not increase lipid peroxide formation to the level expected from the relative peroxidizability index (P-index) of the total tissue lipids. The results suggested the existence of some suppressive mechanisms against DHA-induced tissue lipid peroxide formation, as increased tissue ascorbic acid (AsA) and glutathione levels were observed. Therefore, we focused initially on the role of AsA for the suppressive mechanisms. For this purpose, we examined the influence of different levels of dietary AsA (low, moderate, high and excessive levels were 100, 300 (control), 600 and 3000 mg/kg diet respectively) on the tissue lipid peroxide and antioxidant levels in AsA-requiring Osteogenic Disorder Shionogi/Shi-od/od (ODS) rats fed DHA (6.4 % total energy) for 32 or 33 d. Diets were pair-fed to the DHA- and 100 mg AsA/kg diet-fed group. We found that the lipid peroxide concentrations of liver and kidney in the DHA-fed group receiving 100 mg AsA/kg diet were significantly higher or tended to be higher than those of the DHA-fed groups with AsA at more than the usual control level of 300 mg/kg diet. Contrary to this, the liver alpha-tocopherol concentration was significantly lower or tended to be lower in the DHA and 100 mg AsA/kg diet-fed group than those of the other DHA-fed groups. However, tissue lipid peroxide formation and alpha-tocopherol consumption were not suppressed further, even after animals received higher doses of AsA. The present results suggest that higher than normal concentrations of tissue AsA are not necessarily associated with the suppressive mechanisms against dietary DHA-induced tissue lipid peroxide formation.
