Abstract
Metabolic syndrome (MS) is a growing disorder affecting thousands of people worldwide, especially in industrialised countries, increasing mortality. Oxidative stress, hyperglycaemia, insulin resistance, inflammation, dysbiosis, abdominal obesity, atherogenic dyslipidaemia and hypertension are important factors linked to MS clusters of different pathologies, such as diabesity, cardiovascular diseases and neurological disorders. All biochemical changes observed in MS, such as dysregulation in the glucose and lipid metabolism, immune response, endothelial cell function and intestinal microbiota, promote pathological bridges between metabolic syndrome, diabesity and cardiovascular and neurodegenerative disorders. This review aims to summarise metabolic syndrome's involvement in diabesity and highlight the link between MS and cardiovascular and neurological diseases. A better understanding of MS could promote a novel strategic approach to reduce MS comorbidities.

Abstract
Marine biodiversity has emerged as a very promising resource of bioactive compounds and secondary metabolites from different sea organisms. The sponge's secondary metabolites demonstrated various bioactivities and potential pharmacological properties. This systematic review of the literature focuses on the advances achieved in the antioxidant potential of marine sponges in vitro. The review was performed in accordance with PRISMA guidelines. The main inclusion criterion for analysis was articles with identification of compounds from terpene classes that demonstrate antioxidant activity in vitro. Searching in three different databases, two hundred articles were selected. After screening abstracts, titles and evaluating for eligibility of manuscripts 14 articles were included. The most performed analyzes to detect antioxidant activity were scavenging activity 2,2-diphenyl-1-picrylhydrazyl (DPPH) and measurement of intracellular reactive oxygen species (ROS). It was possible to identify 17 compounds of the terpene class with pronounced antioxidant activity in vitro. Scientific evidence of the studies included in this review was accessed by the GRADE analysis. Terpenes play an important ecological role, moreover these molecules have a pharmaceutical and industrial application.

Abstract
The subject of food-medicines (foods ingested in order to obtain a therapeutic activity or to prevent diseases) is garnering increasing attention from both ethnobiologists and ethnopharmacologists as diet-related chronic diseases are one of the major problems resulting in a large proportion of deaths globally, which calls for interest from the scientific community to make sensible decisions in the field of food and medicine. In this regard, the current study is an important attempt at providing baseline data for developing healthy and curative food ingredients. This study aimed at recording the culinary and medicinal uses of wild food plants (WFPs) in the remote Mastuj Valley, located at the extreme north of Chitral District, Pakistan. An ethnobotanical survey was completed via 30 in-depth semi-structured interviews with local knowledge holders to record the food and medicinal uses of WFPs in the study area. A total of 43 WFPs were recorded, most of which were used as cooked vegetables and raw snacks. Leaves were the most frequently used plant part. A remarkable proportion (81%) of use reports for the recorded wild plant taxa were quoted as food-medicines or medicinal foods, while very few were reported as either food or medicines, without any relationship between uses in these two domains. Previous ethnomedicinal studies from nearby regions have shown that most of the recorded wild plants have been used as medicines, thus supporting the findings of the current study. A literature survey revealed that many of the reported medicinal uses (33%) for the quoted WFPs were not verifiable on PubMed as they have not been studied for their respective medicinal actions. We observed that most of the plants quoted here have disappeared from the traditional food and medicinal system, which may be attributed to the invasion of the food market and the prevalence of allopathic medicine. However, knowledge of these wild plants is still alive in memory, and women are the main holders of cultural knowledge as they use it to manage the cooking and processing of WFPs. Therefore, in this context, we strongly recommend the preservation of local biocultural heritage, promoted through future development and educational programs, which could represent a timely response to the loss of cultural and traditional knowledge.

A systematic review on COVID-19 pandemic with special emphasis on curative potentials of Nigeria based medicinal plants. Heliyon 2020; 6:e04897. [PMID: 32929412 PMCID: PMC7480258 DOI: 10.1016/j.heliyon.2020.e04897] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 07/16/2020] [Accepted: 09/07/2020] [Indexed: 01/08/2023] Open
Abstract
Despite the frightening mortality rate associated with COVID-19, there is no known approved drug to effectively combat the pandemic. COVID-19 clinical manifestations include fever, fatigue, cough, shortness of breath, and other complications. At present, there is no known effective treatment or vaccine that can mitigate/inhibit SARS-CoV-2. Available clinical intervention for COVID-19 is only palliative and limited to support. Thus, there is an exigent need for effective and non-invasive treatment. This article evaluates the possible mechanism of actions of SARS-CoV-2 and present Nigeria based medicinal plants which have pharmacological and biological activities that can mitigate the hallmarks of the pathogenesis of COVID-19. SARS-CoV-2 mode of actions includes hyper-inflammation characterized by a severe and fatal hyper-cytokinaemia with multi-organ failure; immunosuppression; reduction of angiotensin-converting enzyme 2 (ACE2) to enhance pulmonary vascular permeability causing damage to the alveoli; and further activated by open reading frame (ORF)3a, ORF3b, and ORF7a via c-Jun N- terminal kinase (JNK) pathway which induces lung damage. These mechanisms of action of SARS-CoV-2 can be mitigated by a combination therapy of medicinal herbs based on their pharmacological activities. Since the clinical manifestations of COVID-19 are multifactorial with co-morbidities, we strongly recommend the use of combined therapy such that two or more herbs with specific therapeutic actions are administered to combat the mediators of the disease.

Abstract
ABSTRACT A total of 640 one-day-old Cobb broiler chicks, half male and half female, were reared up to 49 days of age. A completely randomized 2 × 4 factorial design was used. Experimental treatments consisted of four levels of organic zinc supplementation and one control (inorganic zinc supplementation) and two levels of sex (female and male), with four replicates of 16 birds per experimental plot. Animal performance, carcass and cut yields, and meat quality were evaluated. Feed intake increased with zinc supplementation. Broilers that received the lowest level of organic zinc showed better feed conversion than those fed an equivalent level of inorganic zinc. Increased levels of organic zinc reduced the abdominal fat content in females but impaired the oxidative stability of meat. The results showed that male broilers have better performance, carcass yield, and meat quality than females and that organic zinc improves broiler feed conversion and reduces abdominal fat but increases lipid oxidation in meat.

Abstract
Cardiovascular disease is the leading global cause of death in Western countries, and its development is largely associated with unhealthy dietary patterns. A large body of scientific evidence has reported that nutrition might be the most preventive factor of cardiovascular disease death and could even reverse heart disease. Processes of chronic inflammation and oxidative distress share triggers that are modifiable by nutrition. This review aimed to identify potential targets (food patterns, single foods or individual nutrients) for cardiovascular disease prevention, and analyse the mechanisms implicated in their cardioprotective effects.

Abstract
Alfalfa polysaccharide (APS) is a bioactive component extracted from alfalfa that exhibits potent antioxidant properties. However, the cellular and molecular mechanisms underlying these properties remain unclear. To explore the molecular mechanism by which APS exerts antioxidant effects, an H2O2-induced oxidative stress mouse embryonic fibroblast (MEF) model was established. Cell proliferation, antioxidant enzyme activity, immune cytokine expression, and related protein expression were examined in APS-supplemented or non-supplemented conditions. The results suggested that APS strengthened the antioxidative capacity of MEFs, increasing cell proliferation, superoxide dismutase activity (SOD), and the total antioxidant capacity (T-AOC). In addition, APS reduced the secretion of interleukin (IL)-6 and IL-8 as well as expression of the proinflammatory gene retinoic acid-inducible gene I (RIG-I). APS was also able to activate the mitogen-activated protein kinase (MAPK) pathway, which promoted the translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) to the nucleus. However, expression of nuclear factor-κB (NF-κB) was decreased after APS treatment. Overall, these results suggest that APS relieves H2O2-induced oxidative stress in MEFs by activating MAPK/Nrf2 signaling and suppressing NF-κB signaling. To the best of our knowledge, this is the first study to link APS with MAPK/Nrf2, NF-κB and RIG-I, thus providing new perspectives regarding the mechanisms of the antioxidant activity of APS.

Abstract
The aim of this study was to investigate the possible mechanism for increasing the antioxidant activity on peptide Glutamine-Tryptophan-Phenylalanine-Histidine (QWFH) from pine nut (Pinus koraiensis) protein by a pulsed electric field (PEF). The antioxidant capacity of PEF-treated QWFH increased significantly (p < 0.05) through 1,1-diphenyl-2-pycryl-hydrazyl radical scavenging and oxygen radical absorbance capacity assays. A series of mechanism exploration methods, including reversed-phase high-performance liquid chromatography, ultraviolet absorption spectroscopy, intrinsic fluorescence spectra, circular dichroism spectroscopy, and 1D and 2D nuclear magnetic resonance spectroscopies, were applied. QWFH chain was not cleaved by the PEF treatment, while more aromatic amino acids (Trp and Phe) were exposed to the polar solvent. In addition, the content of random coil of QWFH in solution was increased and its active hydrogen was changed after the PEF treatment. Moreover, the long-range connectivity between OH (14.234 ppm) on 4-H His, Nα H (7.295 ppm) on 3-H Phe, and Nα H2 (6.801 ppm) on 1-H Gln disappeared due to the PEF. PRACTICAL APPLICATIONS: Antioxidants have been extensively explored as a potential drug to decrease the risk of certain chronic diseases. Food-derived bioactive compounds are safer than synthetic antioxidants for human health and well-being. And the PEF technology is one of the promising processes for improving the biological activity of food components. Currently, the activity of the antioxidant peptide QWFH increased after a PEF treatment. The basic structure of QWFH did not change, but the unfolding of the secondary structure on the peptide chain and the displacement of the active hydrogen increased the antioxidant activity of the peptide. Thus, the range of application of a PEF has been expanded and it also benefited the development of more functional factors in the functional food industry.

Abstract
Natural dietary agents have attracted considerable attention due to their role in promoting health and reducing the risk of diseases including cancer. Ginger, one of the most ancient known spices, contains bioactive compounds with several health benefits. [6]-Gingerol constitutes the most pharmacologically active among such compounds. The aim of the present work was to review the literature pertaining to the use of ginger extract and [6]-gingerol against tumorigenic and oxidative and inflammatory processes associated with cancer, along with the underlying mechanisms of action involved in signaling pathways. This will shed some light on the protective or therapeutic role of ginger derivatives in oxidative and inflammatory regulations during metabolic disturbance and on the antiproliferative and anticancer properties. Data collected from experimental (in vitro or in vivo) and clinical studies discussed in this review indicate that ginger extract and [6]-gingerol exert their action through important mediators and pathways of cell signaling, including Bax/Bcl2, p38/MAPK, Nrf2, p65/NF-κB, TNF-α, ERK1/2, SAPK/JNK, ROS/NF-κB/COX-2, caspases-3, -9, and p53. This suggests that ginger derivatives, in the form of an extract or isolated compounds, exhibit relevant antiproliferative, antitumor, invasive, and anti-inflammatory activities.

Singh S, Dubey V, Meena A, Siddiqui L, Maurya AK, Luqman S. Rutin restricts hydrogen peroxide-induced alterations by up-regulating the redox-system: An in vitro, in vivo and in silico study. Eur J Pharmacol 2018; 835:115-125. [PMID: 30075225 DOI: 10.1016/j.ejphar.2018.07.055] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2018] [Revised: 07/28/2018] [Accepted: 07/30/2018] [Indexed: 11/16/2022]
Abstract
Rutin, a polyphenolic plant flavonoid, is found in citrus fruits, mulberry, cranberries and buckwheat with reported anti-diabetic, anti-fungal, anti-inflammatory and anti-bacterial activity. We appraise the effect of rutin on hydrogen peroxide (H2O2) mediated deregulation of antioxidant enzyme activity, non-enzymatic biomarkers, reactive oxygen species production (in vitro and in vivo) and on echinocyte formation (ex-vivo). In addition to it the interaction studies (in silico) against targeted enzymes and membrane proteins were also performed. A pre-treatment with rutin (16.3 µM) significantly attenuate the altered level of glutathione, sulfhydryl, malondialdehyde and carbonyl content. The activity and expression of catalase, superoxide dismutase, glutathione peroxidase, glutathione reductase and glutathione-S-transferase were also decreased significantly (p < 0.01) in presence of H2O2, while pre-treatment of rutin ameliorates the effect of H2O2. Furthermore, rutin at higher tested concentration protects the morphology of erythrocytes by decreasing the reactive oxygen species level (p < 0.01) as compared to H2O2 treatment. In silico analysis with selected membrane proteins and enzymes revealed that the rutin did not modulate the structure and function of the preferred proteins. In addition, rutin down regulates the inducible nitric oxide synthase expression and up-regulate the nuclear factor (erythroid-related factor 2) expression. Moreover, the lower mean erythrocyte fragility values of rutin (0.53 ± 0.024-0.61 ± 0.014) alone or with H2O2 (0.65 ± 0.021) indicate the protection and non-toxic behaviour. These finding suggests that rutin; a nutritional compound can reduce oxidative stress induced by H2O2 by increasing the expression of Nrf2 and endogenous antioxidant enzymes.

Abstract
BACKGROUND Carissa carandas L. is known in folk medicine for its anti-inflammatory and hepatoprotective activities. Meanwhile it is an evergreen shrub that constitutes a continuous source of leaves throughout the year. HYPOTHESIS/PURPOSE The leaves of Carissa carandas L. may be rich in compounds that can be used as safe anti-inflammatory and antioxidant remedies. The combined antioxidant and anti-inflammatory activities provoked the study of the hepatoprotective effects. STUDY DESIGN To isolate major constituents from the leaves of Carissa carandas L. and test their anti-inflammatory and antioxidant activities in-vivo and in-vitro. METHODS The leaves of Carissa carandas L. were extracted with 80% MeOH and then defatted with CHCl3 to yield Carissa carandas defatted extract (CCDE). The extract was chemoprofiled using UPLC-MS/MS to stand for major constituents, then subjected to different chromatographic separation steps and naringin (NG) was isolated in a high yield. The anti-inflammatory activity of NG was investigated in-vivo by carrageenan induced hind rat paw edema model at two dose levels (50 and 25 mg/kg). The anti-inflammatory activity was also evaluated in-vitro by measuring its inhibitory effect on LPS induced release of NO from RAW 264.7 macrophages. The antioxidant activity was evaluated by superoxide and DPPH radical scavenging ability. The safety of NG was tested against primary rat hepatocytes. The hepatoprotective effect of CCDE was evaluated by detecting its effects on serum liver function markers and liver cell oxidative stress markers. RESULTS NG exhibited potent inhibition of inflammation as compared to indomethacin (20 mg/kg). NG inhibited LPS induced release of NO from macrophages (IC50, 6.4 μM). NG showed significant antioxidant activity as it scavenged the superoxide radical (EC90, 10.95 μM) and DPPH radical (EC50, 11.2 μM). CCDE inhibited the elevation of the serum liver marker enzymes and increased GSH and decreased MDA contents in the liver homogenate. Liver histopathology supported the biochemical findings. CONCLUSION C. carandas has potent anti-inflammatory, antioxidant and hepatoprotective activities.

Abstract
In the current study, African catfish, Clarias gariepinus, was exposed to a sublethal concentration of carbofuran (CF) to investigate its negative effects on biochemical and oxidative stress biomarkers. Also, the putative role of lycopene (LYC) administration in alleviating these negative effects was evaluated. Fish were divided into six groups in triplicates as follows: group I was without treatment, group II was orally administered corn oil, group III was orally administered 18 mg LYC/kg body weight, group IV was exposed to 0.121 mg CF/L, group V was orally administered 9 mg LYC/kg body weight and exposed to 0.121 mg CF/L, and group VI was orally administered 18 mg LYC/kg body weight and exposed to 0.121 mg CF/L for 4 weeks. At the end of this period, blood and tissue (liver and kidney) samples were collected and biochemical and oxidative stress biomarkers were analysed. Also, histopathological changes were determined. Carbofuran caused significant increments of glucose, cortisol, aspartic amino transferase, alanine amino transferase, cholesterol, urea, and creatinine; meanwhile, serum acetylcholinesterase, total protein, albumin, and total lipids were significantly reduced. Significant increments in hepatic and renal malondialdehyde (MDA) and superoxide dismutase (SOD) levels and marked reduction in hepatic and renal catalase (CAT), glutathione (GSH), and total antioxidant capacity (TAC) levels were observed in CF-exposed fish comparing to the control group. Treatment with LYC attenuated the CF-induced oxidative stress, and this improvement was more pronounced in fish received the high LYC dose (18 mg/kg body weight). Further, congestion of the central vein with infiltration of mononuclear inflammatory cells, vacuolar necrosis, and haemorrhage was observed in the livers of CF-exposed fish. Oral administration of LYC reduced behavioural changes and histopathological alterations. All the altered biochemical parameters and antioxidant biomarkers were also restored to be near the normal levels. The obtained results evoked that LYC administration alleviated the destructive effects of carbofuran and reduced its toxicity effect on African catfish.

Abstract
A new class of pyrazolo[4,3-c]quinoline (5a-i, 7a-b) and pyrano[3,2-c]quinoline (9a-i) derivatives were designed and synthesized in moderate to good yields by microwave conditions. To enhance the yield of pyrano[3,2-c]quinoline derivatives, multicomponent one-pot synthesis has been developed. The synthesized compounds were identified by spectral and elemental analyses. Compounds 9a and 9i showed good antibacterial activity against Gram-positive and Gram-negative bacterial strains. All of the new compounds exhibited weak to moderate antioxidant activity, compound 9d exerted significant antioxidant power. The cytotoxicity of these compounds were also evaluated against MCF-7 (breast) and A549 (Lung) cancer cell lines. Most of the compounds displayed moderate to good cytotoxic activity against these cell lines. Compound 9i was found to be significantly active in this assay and also induced cell death by apoptosis. Molecular docking studies were carried out using EGFR inhibitor in order to determine the molecular interactions.

Abstract
Our aim was to investigate the antioxidant potential of lycopene in different experimental liver models: in vitro, to evaluate the influence of lycopene on reactive oxygen species (ROS) production mediated by the PKC pathway and in vivo, to evaluate the protective effects of lycopene in an experimental model of hepatotoxicity. The in vitro study assessed the lycopene antioxidant potential by the quantification of ROS production in SK-Hep-1 cells unstimulated or stimulated by an activator of the PKC pathway. The role of NADPH oxidase was evaluated by measuring its inhibition potential using an inhibitor of this enzyme. In the in vivo study, male C57BL/6 mice received lycopene (10 or 100 mg/kg by oral gavage) and 1 h later, acetaminophen (APAP) (500 mg/kg) was administrated. Lycopene decreased ROS production in SK-Hep-1 cells through inhibition of NADPH oxidase, brought about in the PKC pathway. Lycopene improved hepatotoxicity acting as an antioxidant, reduced GSSG and regulated tGSH and CAT levels, reduced oxidative damage primarily by decreasing protein carbonylation, promoted the downregulation of MMP-2 and reduced areas of necrosis improving the general appearance of the lesion in C57BL/6 mice. Lycopene is a natural compound that was able to inhibit the production of ROS in vitro and mitigate the damage caused by APAP overdose in vivo.

Abstract
Baccharis trimera, popularly known as "carqueja", is a native South-American plant possessing a high concentration of polyphenolic compounds and therefore high antioxidant potential. Despite the antioxidant potential described for B. trimera, there are no reports concerning the signaling pathways involved in this process. So, the aim of the present study was to assess the influence of B. trimera on the modulation of PKC signaling pathway and to characterize the effect of the nicotinamide adenine dinucleotide phosphate oxidase enzyme (NOX) on the generation of reactive oxygen species in SK Hep-1 cells. SK-Hep 1 cells were treated with B. trimera, quercetin, or rutin and then stimulated or not with PMA/ionomycin and labeled with carboxy H2DCFDA for detection of reactive oxygen species by flow cytometer. The PKC expression by Western blot and enzyme activity was performed to evaluate the influence of B. trimera and quercetin on PKC signaling pathway. p47 phox and p47 phox phosphorylated expression was performed by Western blot to evaluate the influence of B. trimera on p47 phox phosphorylation. The results showed that cells stimulated with PMA/ionomycin (activators of PKC) showed significantly increased reactive oxygen species production, and this production returned to baseline levels after treatment with DPI (NOX inhibitor). Both B. trimera and quercetin modulated reactive oxygen species production through the inhibition of PKC protein expression and enzymatic activity, also with inhibition of p47 phox phosphorylation. Taken together, these results suggest that B. trimera has a potential mechanism for inhibiting reactive oxygen species production through the PKC signaling pathway and inhibition subunit p47 phox phosphorylation of nicotinamide adenine dinucleotide phosphate oxidase.

Abstract
An oxidative burst occurs during pregnancy due to the large consumption of oxygen in the tissues and an increase in metabolic demands in response to maternal physiological changes and fetal growth. This study aimed to determine the oxidative profile and activity of δ-aminolevulinate dehydratase (δ-ALA-D) in pregnant women who received iron supplementation. Oxidative stress parameters were evaluated in 25 pregnant women with iron supplementation, 25 pregnant women without supplementation and 25 non-pregnant women. The following oxidative stress parameters were evaluated: thiobarbituric acid reactive substances (TBARS), protein thiol groups (P-SH), non-protein thiol levels (NP-SH), vitamin C levels, catalase and δ-ALA-D activity. Markers of oxidative stress and cell damage, such as TBARS in plasma were significantly higher in pregnant women without supplementation. Levels of P-SH, NP-SH and δ-ALA-D activity were significantly lower in pregnant women without supplementation compared to non-pregnant and pregnant women with supplementation, while vitamin C levels were significantly lower in pregnant women without supplementation when compared to non-pregnant women. The increase in the generation of oxidative species and decrease of antioxidants suggest the loss of physiological oxidative balance during normal pregnancy, which was not observed in pregnant women with iron supplementation, suggesting a protective effect of iron against oxidative damage.

Abstract
Carotenoid is a group of pigments naturally present in vegetal raw materials that have biological properties. These pigments have been used mainly in food, pharmaceutical, and cosmetic industries. Currently, the industrial production is executed through chemical synthesis, but natural alternatives of carotenoid production/attainment are in development. The carotenoid extraction occurs generally with vegetal oil and organic solvents, but supercritical technology is an alternative technique to the recovery of these compounds, presenting many advantages when compared to conventional process. Brazil has an ample diversity of vegetal sources inadequately investigated and, then, a major development of optimization and validation of carotenoid production/attainment methods is necessary, so that the benefits of these pigments can be delivered to the consumer.

Abstract
Oxidative stress plays a key role in numerous disease processes including chronic kidney disease (CKD). In general, oxygen metabolism leads to the formation of reactive oxygen species (ROS) dangerous to cells. Although enzymes and low-molecular-weight antioxidants protect against ROS, chronic imbalances of formation and elimination can eventually overwhelm endogenous defenses leading to deleterious consequences. In CKD, glutathione peroxidases (GSH-Px) play an important role in ROS metabolism. Plasma GSH-Px is synthesized in the kidney and requires selenium (Se) as a cofactor. Interestingly, Se and plasma GSH-Px are both significantly reduced in CKD, especially for those patients on hemodialysis. Supplementation of Se in these patients results in modest increases of GSH-Px, presumably from residual renal tissue. Kidney transplantation rapidly restores plasma GSH-Px. In this chapter, the relevance of these findings to CKD is explored with emphasis on renal disease processes and impact on attendant disorders including cancer and cardiovascular disease.

Abstract
There is increasing evidence that free radicals play an important role in neuronal damages induced by diabetes mellitus or cerebral ischemia insults. Antioxidants with free radical scavenging activities have been shown to be beneficial and neuroprotective for these pathological conditions. Here, we report free radical scavenging activity and neuroprotective potential of D138, one copper(II)/zinc(II) Schiff-base complex derived from N,N'-2(2-hydroxynaphthylmethylidene)-1,3-propanediamine. The data from three in vitro assays, 2,2-diphenyl-1-picrylhydrazyl assay, nitro blue tetrazolium assay and hydroxyl radical scavenging assay, indicated that D138 presented a potent free radical scavenging activity. The neuroprotective and antioxidative effects of D138 were further evaluated in vivo using bilateral common carotid artery occlusion (BCCAO) mouse model and streptozotocin (STZ) diabetic mouse model. Our results indicated that treatment of D138 significantly ameliorated the hippocampal neuronal damage and the oxidative stress levels in these animal models. Moreover, D138 also reversed the behavioral deficiencies induced by BCCAO or STZ, as assessed by Y-maze test and fear conditioning test. In conclusion, all these findings support that D138 exerts free radical scavenging and neuroprotective activities and has the potentials to be a potent therapeutic candidate for brain oxidative damage induced by cerebral ischemia or diabetes mellitus.

Abstract
Background Sutherlandia frutescens (L.) R.Br. (SF) is a South African plant that is widely used to treat stress, infections, cancer, and chronic diseases, many of which involve oxidative stress. The aim of the study was to quantitatively assess the antioxidant potential of SF extracts in cell-free system as well as in cell lines. Methods Dried SF vegetative parts were extracted using six different solvents, and the extracts were assessed for total phenolic and flavonoid contents, total reducing power, iron chelating capacity, and free radical scavenging power, including, scavenging of hydroxyl radicals, superoxide anions, nitric oxide, and hydrogen peroxide. We further investigated the freeze-dried hot water extract of SF (SFE) to assess its effect against oxidative stress induced by tert-butyl hydroperoxide (t-BHP), an organic peroxide. Three different cell lines: Chinese hamster ovary (CHO), human hepatoma (HepaRG), and human pulmonary alveolar carcinoma (A549) cells, were employed to determine cell viability, intracellular reactive oxygen species (ROS) levels, and reduced to oxidized glutathione levels (GSH/GSSG). Results The results indicated that: (1) SF extracts have significant antioxidant potential that is dependent upon the nature of the extraction solvent and (2) SFE protects against tBHP-induced oxidative stress in cells by scavenging ROS and preserving intracellular GSH/GSSG. Conclusion Oxidative stress is implicated in a number of disorders, and due to the public’s concerns about synthetic antioxidants, various natural antioxidants are being explored for their therapeutic potential. Our findings support claims for S. frutescens being a promising adjunctive therapeutic for oxidative stress-related health problems.

Abstract
INTRODUÇÃO: Os radicais livres produzidos durante os exercícios podem exceder o sistema de defesa antioxidante, provocando danos oxidativos de biomoléculas específicas. As lesões causadas pelos radicais livres nas células podem ser prevenidas ou reduzidas por meio da atividade de antioxidantes naturais, sendo estes encontrados em muitos alimentos. O licopeno é um dos mais potentes carotenoides com ação antioxidante, sendo utilizado na prevenção da carcinogênese e aterogênese por proteger moléculas como lipídios, lipoproteínas de baixa densidade (LDL), proteínas e DNA.OBJETIVO: Investigar a atuação do licopeno a uma possível ação protetora das fibras musculares cardíacas e esqueléticas contra o estresse oxidativo, durante a atividade física exaustiva, a qual provocaria alterações morfológicas nesses tecidos. Método: Na realização dos experimentos foram utilizados 32 ratos machos adultos divididos em quatro grupos, sendo dois grupos controles e dois grupos treinados sem e com suplementação de licopeno (6 mg por animal). Os animais dos grupos treinados foram submetidos a 42 sessões de natação por nove semanas, com sessões diárias de natação, cinco dias por semana, com sobrecarga produzida pelo aumento do tempo de treinamento. A avaliação morfológica foi realizada por meio de lâminas histológicas dos tecidos cardíaco e muscular esquelético.RESULTADOS: Modificações teciduais cardíacas e musculares esqueléticas no grupo treinado sem suplementação com licopeno foram observadas, sendo que o grupo treinado suplementado apresentou aspecto morfológico normal. Nos grupos sedentários controle suplementado e não suplementado não houve alteração em relação às características histológicas dos tecidos.CONCLUSÃO: Podemos afirmar que o licopeno exerceu um efeito protetor nos músculos cardíaco e esquelético contra o estresse oxidativo, induzido por exercícios exaustivos, além de promover uma neovascularização do tecido cardíaco, podendo ser utilizado com eficiência por atletas e praticantes de atividade física.

Abstract
PURPOSE OF REVIEW Oxidative damage to cells and tissues is considered involved in the aging process and in the development of chronic diseases in humans, including cancer and cardiovascular diseases, the leading causes of death in high-income countries. This has stimulated interest in the preventive potential of antioxidant supplements. Today, more than one half of adults in high-income countries ingest antioxidant supplements hoping to improve their health, oppose unhealthy behaviors, and counteract the ravages of aging. RECENT FINDINGS Older observational studies and some randomized clinical trials with high risks of systematic errors ('bias') have suggested that antioxidant supplements may improve health and prolong life. A number of randomized clinical trials with adequate methodologies observed neutral or negative results of antioxidant supplements. Recently completed large randomized clinical trials with low risks of bias and systematic reviews of randomized clinical trials taking systematic errors ('bias') and risks of random errors ('play of chance') into account have shown that antioxidant supplements do not seem to prevent cancer, cardiovascular diseases, or death. Even more, beta-carotene, vitamin A, and vitamin E may increase mortality. Some recent large observational studies now support these findings. According to recent dietary guidelines, there is no evidence to support the use of antioxidant supplements in the primary prevention of chronic diseases or mortality. SUMMARY Antioxidant supplements do not possess preventive effects and may be harmful with unwanted consequences to our health, especially in well-nourished populations. The optimal source of antioxidants seems to come from our diet, not from antioxidant supplements in pills or tablets.

Abstract
A series of novel 5-aryl-3-cyclopropyl-4,5-dihydropyrazole derivatives 2a-p were synthesized via cyclization of chalcones 1a-h with thiosemicarbazide or semicarbazide HCl and evaluated as anti-inflammatory/antioxidant agents. The structures were confirmed by elemental analyses and spectral data. The free radical scavenging activity toward superoxide was determined. Their effect on hepatocytes viability and nitric oxide (NO) production in LPS-stimulated macrophages was also determined. The results showed that compounds 2e and 2n demonstrated the highest free-radical scavenging and anti-inflammatory activities, thus can be useful in the prevention of oxidative stress and inflammation-related disorders.

Abstract
Background The objective of the present study was to examine the influence of adding various amounts beetroot (Beta vulgaris) crisps on gastrointestinal function, antioxidant status and blood and liver lipid profiles in a high fat diet-induced dyslipidaemic rat model; Results The intake of a dyslipidaemic diet increased the serum total cholesterol, total cholesterol-to-HDL-cholesterol ratio, atherogenic index, hepatic total cholesterol and triacylglycerols, suppressed production of short-chain fatty acids and decreased total antioxidant status and blood glutathione peroxidase activity. Oral administration of all tested amounts of beetroot crisps prevented the rise in serum total cholesterol and triacylglycerols levels. The treatment with the addition of 3% crisps also decreased hepatic total cholesterol level and activity of AST in serum. The experimental addition of crisps likewise resulted in a tendency towards a higher total SCFA pool and activity of glutathione peroxidase and a lower serum glucose level (p = 0.080, p = 0.061 and p = 0.067, respectively); Conclusions Results of the presented study suggest that the addition of beetroot crisps could alleviate metabolic changes in dyslipidaemic diet-administered rats.

Abstract
The influence of different cooking regimes such as boiling, oven, microwave and hot-air drying on the retention of total phenolics (TP), total carotenoids (TC) and in vitro antioxidant capacity (AC) for three colored arracacha roots was studied. Continuous losses of TP, TC and AC during the course of the different cooking processes were observed. Boiling at 99.5° C for 20 min turned to be the best method to cook this root due to a high retention of TP, TC and AC in comparison to oven cooking at 200° C for 45 min and microwave cooking at 800 W for 5 min. During boiling, chlorogenic and caffeic acids and derivatives remained relatively stable. The drying temperature was negatively correlated to the residual content of TP and AC for the yellow and cream arracacha roots, but for the cream/purple arracacha variety, blanching preserved the TP and AC. Significant losses in chlorogenic and caffeic acids and derivatives were mainly observed during hot-air drying. These results suggested that TP are responsible to a large extent of the AC displayed by arracacha root during the different evaluated cooking regimes.

Abstract
In recent years, there has been a great deal of attention toward the field of free radical chemistry. Free radicals reactive oxygen species and reactive nitrogen species are generated by our body by various endogenous systems, exposure to different physiochemical conditions or pathological states. A balance between free radicals and antioxidants is necessary for proper physiological function. If free radicals overwhelm the body's ability to regulate them, a condition known as oxidative stress ensues. Free radicals thus adversely alter lipids, proteins, and DNA and trigger a number of human diseases. Hence application of external source of antioxidants can assist in coping this oxidative stress. Synthetic antioxidants such as butylated hydroxytoluene and butylated hydroxyanisole have recently been reported to be dangerous for human health. Thus, the search for effective, nontoxic natural compounds with antioxidative activity has been intensified in recent years. The present review provides a brief overview on oxidative stress mediated cellular damages and role of dietary antioxidants as functional foods in the management of human diseases.

Abstract
OBJECTIVE This study evaluated the preliminary effects of intense physical training (swimming) on oxidative stress in rats with nutritional deficiencies. METHODS Rats were fed with a standard diet or a diet deficient in vitamins and minerals for 4 months. The deficient diet contained one-fourth of the recommended vitamin and mineral levels for rats. From the second month, half of the animals were subjected to a swimming exercise in a plastic container with water maintained at 34 +/- 1 degrees C for 1 h/d, five times per week, for 11 wk. The rats were subjected to swimming exercise with loads attached to the dorsal region, which were progressively increased according to their body weight (1% to 7%). Sedentary rats were transported to the experimental room and handled as often in a similar way as the exercise group, except that they were not put in water. RESULTS In the exercised group, blood lactate levels were significantly lower and the heart weight/body weight ratio was significantly higher than in the sedentary group (P < 0.05). Increased lipid peroxidation was observed in the liver, heart, and skeletal muscle of rats fed with the deficient diet, but it was completely reversed by exercise. Exercise also decreased lipid peroxidation levels in the heart and skeletal muscle of rats fed with the standard diet (P < 0.05). CONCLUSION This pilot study leads to the continuity of the studies, because the partial results observed suggest that inadequate nutrition may enhance oxidative stress, and that intense chronic physical training may activate antioxidant defenses, possibly by hormesis.

Abstract
In this study, we have designed novel chromanyl derivatives that share with alpha-tocopherol a chromanyl head but differ in the lateral chain in: (i) length and saturation (FEBL-45, 50, 70), (ii) position of double bonds in Z or E (FEBL-50 and 53 and their respective 6-chromanyl methyl derivatives FEBL-161 and 162), or (iii) presence of additional antioxidant molecules, such as the catechol compound hydroxytyrosol (FEBL-80) or dopamine (FEBL-82, 95). The efficiency of these compounds in preventing free-radical-induced oxidative stress was investigated in isolated membranes as well as intact cells. The results of this study clearly show that all compounds synthesized were active in: (i) inhibiting AAPH- or tert-BOOH-induced lipid peroxidation in microsomes and (ii) preventing H2O2-induced ROS production, cell damage, and heat-shock protein expression in immortalized RAT-1 fibroblasts. Such effects were dose- and time-dependent. Independent of the kind of pro-oxidant used, differences in the antioxidant potency of these compounds were found in relation to the chemical structure with respect to the natural alpha-tocopherol: (1) The concomitant presence of a chromanyl head and an additional aromatic ring markedly increased the antioxidant potency of the molecule. In particular, FEBL-82 and FEBL-95, resulting from the molecular combination of trolox and dopamine, were much more potent than alpha-tocopherol, alpha-tocotrienol, and the other synthetic compounds. Moreover, they were also more potent than trolox and dopamine, used alone or in combination, suggesting synergistic cooperative interactions in the molecule between chromanyl and catechol moieties. (2) The length of the side chain affected the antioxidant properties of the molecule: FEBL-70, which displays a bulky squalene side chain, was less effective than the natural alpha-tocotrienol and the synthetic FEBL-45 and FEBL-50. (3) The presence of polyunsaturated double bonds in the side chain in the Z configuration (FEBL-53, FEBL-162) increased the antioxidant potency of the molecule with respect to the E configuration (FEBL-50, FEBL-161).

Abstract
It is well-known, that lipid antioxidants can retard the oxidative rancidity of foods caused by atmospheric oxidation, and thus protect oils, fats, and fat-soluble components from their quality degradation. In the last few years, much emphasis has been put on the promotion and use of natural antioxidants, commonly occurring in many fruits and vegetables and thereby produced from various natural extracts. This review gives a summary of previously reported work together with more recent trends in the field of natural antioxidants. Focus is given on the mechanism of actions and the inhibitory effect of certain vitamins against the oxidative degradation of oil-based systems. Moreover, the use of natural phenolics (flavonoids, olive-oil penolics, herb extracts etc.) as antioxidants in numerous lipid food applications is discussed.

Abstract
Na queimadura, os radicais livres são produzidos durante a reposição de fluídos, alterando numerosos componentes, como os ácidos nucléicos, os lipídios e as proteínas. Sendo assim, se, por um lado, essa restauração do fluxo sanguíneo é, em geral, necessária para recuperar a função celular normal, por outro lado a reintrodução do sangue oxigenado nos tecidos isquêmicos contribui para uma produção excessiva de radicais livres derivados do oxigênio, exacerbando a lesão mediada pela isquemia. O papel dos neutrófilos ativados na célula após a queimadura também tem recebido atenção especial. A partir do sistema NADPH oxidase os neutrófilos aderidos podem produzir uma explosão de radical superóxido, produzindo um dano tecidual importante. A queimadura, além de aumentar a produção de radicais livres, também é capaz de impedir os mecanismos de defesa antioxidante, submetendo o paciente queimado ao estresse oxidativo, o qual se constitui em fator perpetuante da resposta inflamatória sistêmica, levando à piora progressiva do estado metabólico. Com esses dados, objetiva-se revisar os principais estudos com a suplementação de antioxidantes em pacientes críticos, com ênfase em pacientes queimados, e descrever os possíveis benefícios dessa intervenção.

Abstract
The aim of this study was to characterize the defatted rice bran (DRB) employing HPLC for identifying the major phytochemicals in DRB and to examine its commercial potential as a source of bioactive phytochemicals leading to value addition of DRB otherwise used as cattle feed. Various solvent extracts showed the presence of oryzanols, tocols, and ferulic acid. Methanol was the most effective extractant under the optimized conditions of a material-solvent ratio of 1:15 (wt./vol.) and a time of extraction of 10h. The yields of total phenols, oryzanols and ferulic acid from DRB with methanol were 2204, 316, and 233 ppm, respectively. Enrichment of antioxidants in the crude methanolic extract (CME) was achieved by sequential extraction and fractionation, resulting in three enriched fractions, viz., acetone extract (AE), acetone extract-lipophilic fraction (AE-LP) and acetone extract-polar fraction (AE-PP). While AE-LP was enriched in oryzanols and tocols by about 65 times, AE-PP was enriched in ferulic acid by 70 times as compared to their contents in DRB.
