The extracts and metabolites of Artocarpus heterophyllus particularly those from leaves, bark, stem and fruit possess several useful bioactive compounds. This review indents to compile various studies on A. heterophyllus and critically evaluates its ethnomedical and ethnopharmacological properties. Several pharmacological studies from A. heterophyllus have conclusively established their mode of action in anti-inflammatory, antimicrobial, antioxidant and anticancer activities. Based on the available data, it is concluded that Artocarpus as a promising source of useful products and opens up new avenues for novel therapeutics.

The seasonal nature of most fruits available in the market coupled with inadequate storage and processing facilities has limited their consumption by majority of the people in the country. Jams made from fruits are good bread spread rather than any other food products because they serve as adequate balance diet and it contains antioxidant such as vitamin C and A which play an important role in preventing cancer, cardiovascular problem and improvement of eyesight. Pawpaw and watermelon fruits have been reported to be nutritive and high in antioxidant properties that can scavenge free radicals, thereby improving the antioxidant status of the body. It is therefore deemed fit to produce jam from these perishable commodities in other to make them available all through the year and as well as adding to varieties of food products. The aqueous extracts of watermelon with pawpaw juice were processed into jam and the physicochemical properties of the jam samples were analysed. The resulting jam samples showed moisture content ranging between 30.60-35.30%, protein 0.40-0.80%, fat 0.20-0.40%, ash 1.20-1.70%, crude fibre 0.10-0.30%, carbohydrate 62.10-67.16%, β-carotene 610-1350µg/100g and ascorbic acid 9.60-15.40mg/100g. The jam samples were found to be very nutritive and high in antimicrobial and antioxidant properties that can scavenge free radicals, thereby can improve the antioxidant status of the body. Sensory evaluation tests showed that the samples were acceptable and compared favourably with the commercial imported brand while sample AA had the highest preference in all the sensory attributes evaluated by the panellists. Microbiological examination also showed that the jam samples had total plate count ranging from 4.10x101 to 2.00 x101 cfu/g, yeast and mould count ranged from 2.10x101 to 1.00 x101cfu/g with no observable coliform count.

Emerging evidence indicates that micronutrient deficiency could play a significant role in the pathogenesis and progression of many chronic diseases including diabetes mellitus, hypertension, obesity, dyslipidemia, hyperuricemia, kidney disease, cancer, anemia and other cardio-metabolic and neurodegenerative diseases through the induction of Insulin resistance (IR). However, there are still gaps in our scientific knowledge regarding the links between micronutrient deficiencies, IR, and cardio metabolic disorders. This review provides current information on recent advances and a global perspective regarding the relationship between micronutrient deficiency, IR, and cardio metabolic disorders. Empirical evidence indicates that deficiencies in either micronutrients associated with insulin activity (such as Chromium, manganese, magnesium, and iron) or antioxidant enzyme cofactors (such as vitamin A, copper, zinc, and manganese) could impact several physiological processes leading to a cascade of metabolic and biochemical derangements such as B-cell apoptosis, loss of islet cell mass, defective tyrosine kinase activity, oxidative stress, pancreatic β-cell dysfunction, reduction in lean body mass, defective insulin signaling mechanism, elevated protein kinase C activity, and excess intracellular calcium. Collaboratively, these states of metabolic malfunctioning are associated with IR, which triggers the onset of many cardio metabolic diseases. Undoubtedly, the prevention of micronutrient deficiency may indeed ameliorate the incidence of IR and cardio-metabolic disorders in those at risk and in the general population.

Tea (Black tea and Green tea) are one of the most widely consumed beverages in the world. However, with the increasing interest in the health properties of tea and a significant rise in scientific investigation, this review covers some of the recent findings on the health benefits of both green and black tea. The mechanisms of action of various black and green tea components have been presented. Green tea contains a unique set of catechins that responsible for its biological activity potentially relevant to the prevention of diseases. Although there has been much focus on the biological property of the major tea catechins, black tea offers major health benefits either due to the presence of the catechins in epimerized form or some other active components of both varieties of tea. Characteristics unrelated to the antioxidant properties of green and black tea might also be responsible for their therapeutic potential in preventing diseases. Synergistic effect of the tea constituents is increasingly recognized as being potentially important to the medicinal benefits of black and green tea. The studies indicate that tea has the potential of being a part of diet for healthy living.

Pine honey represents the major type of honey produced in Greece. In that sense, the aim of the present study was to investigate if specific physicochemical and bioactive properties could serve as markers of its geographical origin. For this purpose, forty pine honey samples were collected during harvesting years 2011 and 2012 from Halkidiki and Thassos, the well-known pine honey producing areas in Greece. Physicochemical parameters taken into account, using conventional and literature cited methods, were: pH, CIE colour parameters L*,a*,b*, and browning index. Furthermore, colour intensity and the in vitro radical scavenging activity were estimated by the application of spectrometric assays. Results showed that, pine honeys exhibited statistically significant differences (p<0.05) in pH, colour intensity, and radical scavenging activity, depending on geographical origin. On the basis of radical scavenging activity results obtained, pine honeys proved to have a high in vitro antioxidant “character’’. Finally, perfect Pearson’s correlations (r=1) at the confidence level p<0.01 were obtained for the sets: pH-browning index, pH-radical scavenging activity, and browning index -radical scavenging activity, with respect to geographical origin.

Age related macular degeneration is a severe disease of mainly elderly people and leads to central vision loss because of the degeneration of the retinal pigment epithelium [1]. Genetic and environmental factors are responsible for the accumulation of extracellular material and deposit formation near the retinal pigment epithelial (RPE) layer, which leads to loss of photoreceptors and induction of chronic inflammation. The deposits are composed of lipids and proteins including many complement proteins, indicating the involvement of the complement system in the degenerative process and chronic inflammation [2]. So far there is no treatment for the dry form of AMD, except nutritional supplementation with antioxidants and vitamins [3]. Combined with a prolonged lifetime expectation in developed countries, AMD is developing to a social and economic burden. Therefore, there is an urgent need for a treatment of AMD that can delay disease manifestation and progression for several years. 

Background: Herbal essential oil contains pharmacological benefits for intervention treatment of various diseases. Studies have demonstrated its antimicrobial, antioxidant, and anti-inflammatory effect involving in vitro cell culture and preclinical animal models. It has been also traditionally used to reduce anxiety and hypertension in human. However, scientific studies elucidating its mechanism of action and pharmacological targets, as well as its effectiveness and safety as phytotherapeutic compounds are still progressing. Recent studies showed its promising effect in depression-cardiovascular disease intervention. However, comprehensive evaluations to enlighten latest advancement and potential of herbal essential oil are still lacking. Objective: In this systematic review, the depression-cardiovascular effects of herbal essential oil on lipid profile, biochemical and physiological parameters (e.g haemodynamic) are presented. The route of delivery and mechanism of action as well as main bioactive compounds present in respective essential oil are discussed. Methods: Article searches are made using NCBI PubMed, PubMed Health, SCOPUS, Wiley Online, tandfonline, ScienceDirect and Espacenet for relevant studies and intellectual properties related to essential oil, depression and cardiovascular disease. Results: In experimentation involving in vitro, in vivo and clinical trials, herbal essential oil showed its effectiveness in reducing coronary artery disease (narrowing of the arteries), heart attack, abnormal heart rhythms, or arrhythmias, heart failure, heart valve disease, congenital heart disease, heart muscle disease (cardiomyopathy), pericardial disease, aorta disease, Marfan syndrome and vascular (blood vessel) disease. Conclusion: This review gives a valuable insight on the potential of essential oil in the intervention of depression associated with cardiovascular diseases. Studies showed that herbal essential oil could act as vasodepressor, calcium channel blocker, antihyperlipidemia, anticoagulant, antiatherogenesis and antithrombotic. It can be proposed as an interventional therapy for depression-cardiovascular disease to reduce doses and long-term side-effect of current pharmacological approach.

Background: Cyclophosphamide is used for the treatment of malignant and non-malignant diseases, but, it induces oxidative damage and disturbance in the antioxidant defense system. Zinc oxide nanoparticles (ZnO NPs) are used in biomedical applications and consumer products. ZnO-NPs are protected cell membranes against oxidative damage, decrease free radicals and malondialdehyde (MDA) levels, and increase the antioxidant enzyme levels. Objectives: The present aimed to evaluate the ameliorative effect of Zn-O nano-particles on oxidative damage and disturbance in the antioxidant defense system induced by cyclophosphamide in male albino rats. Materials and Methods: 24 adult male albino rats were randomly divided into 4 groups (6 rats of each). Group I (Control group): Received 0.2 ml saline /day i.p. injection for 14 days (day by day), group II, (nZnO group): Received nZnO (5 mg/kg/day) b.w., intraperitoneally for 14 days, Group III (CP group): Received CP (20 mg/kg/day) b.w, day by day for 14 days by intraperitoneal injection, Group IV (CP + ZnO NPs group): Received nZnO group: Received nZnO (5 mg/kg/day) b.w., intraperitoneally for 14 days, plus CP (20 mg/kg/day) b.w., day by day for 14 days by intraperitoneal injection. After 24-hr from the last treatment, all animals were anesthetized using light ether. Blood, lungs, and liver samples were taken and prepared for biochemical measurements. Results: Individual treatment of zinc oxide nanoparticles and CP induced liver cytochrome b5, cytochrome C reductase, and glutathione S-transferase (GST) compared to the control group, while CP increased P450. The combination of nZnO and CP prevents the elevation of cytochrome b5, P450, cytochrome C reductase, and GST compared with the CP treated group. Zinc oxide nanoparticles and CP increased liver thiobarbituric acid reactive substances (TBARS). The combination of nZnO and CP prevents the changes in TBARS concentrations compared with the CP. Injection of CP to rats reduced the activities of serum glutathione reductase (GR) and catalase (CAT) as compared with the control group. However, combination treatment of rats with nZnO and CP increased the activities of these enzymes compared with those treated with CP alone. Zinc oxide nanoparticles and CP increased serum and lung TBARS, while decreased glutathione (GSH) concentration compared to the control group, with more pronounced changes by CP. The combination of nZnO and CP prevents the changes in TBARS and GSH concentrations compared with the CP. Conclusion: It can be concluded that CP induced oxidative stress and disturbance in the antioxidant defense system. Treatment of rats with zinc oxide nano-particles and CP together attenuated the oxidative damage and disturbance in the antioxidant defense system induced by CP. So, Patients treated with CP advised to take nZnO to prevent the side effects of chemotherapy. Further studies are necessary to evaluate the amelioration effect nZnO and other nano-particles against oxidative stress induced by CP in different doses and experimental models.

Nanoparticles affects growth and development of Plant. Zinc is an important micronutrient that regulates various physiological responses in plant. Application of nanoparticles for modulating plants physiological response is a recent practice. Zinc nanoparticles has been widely used in industry for several decades. However, no significant work had been made on its potential use in agriculture. Understanding physiological effect of Zn NP on rice seed germination could suggest the basis for its prospective application in agriculture to improve plant growth. In the present experiment effect of Zn NP was studied in Kmj-6-1-1 which is a commonly growing rice cultivar of Karimganj district of Assam, India. An exposure to Zn NP (0 mg/L, 5mg/L,10mg/L, 15mg/L, 20mg/L & 50mg/L) caused significant changes in radicle and plumule length , mass ( fresh & dry mass) and seed moisture content in rice. Antioxidant enzymes like guaiacol peroxidase (GPx), catalase (CAT), superoxide dismutase (SOD) and gluthathione reductase (GR) also increased due to ZnNP treatment. This suggest that Zn NP may significantly alters antioxidant metabolism during rice seed germination. In conclusion, Zn NP protected rice plants from ROS damage by improving levels of antioxidant enzyme activities during germination. As a consequence the Zn NP treated seeds, showed better potential for germination. Further, genomic analysis of germinating rice seeds are needed to elucidate the molecular mechanisms by which Zn NP modulates germination process in rice.

Hypoxis hemerocallidea Lam is one of the 43 Hypoxis species in South Africa, marketed extensively as over the counter herbal product for the management of several diseases. The plant commercial products link efficacy to hypoxoside 4, its aglycone (rooperol), or β-sitosterol. This study investigated antibacterial and anti-oxidant activities of four other molecules and two extracts from the Hypoxis plant. Visual antioxidant limit of detection and free radical scavenging activities of test samples were determined using 20 mM hydrogen peroxide, 0.4 mM DPPH or ferric reducing antioxidant power assay. Quantitative free radical was determine by spectrophotometric method while antibacterial activity was evaluated using MICs against uropathogens: S. aureus (ATCC25923), S. marcescens (ATCC 14041), P. aeruginosa (ATCC 9721), P. mirabilis (ATCC 33583) and E. coli (ATCC 10536). Anti-oxidant activities visual limit of detection of 0.06 mg/mL and percentage free radical scavenging activity (IC50 = 0.048 - 0.032 mg/ml) for pure compounds 1 - 4 and (IC50 = 0.037 - 0.039 mg/ml) for extracts were obtained. The reducing power IC50 ranged between 0.15 - 0.23 mg/ml for extracts and 0.11-0.35 mg/ml for standards. Antibacterial potentials show a noteworthy to moderate MIC values of 0.20 - 1.56 mg/ml against S. aureus (ATCC 25923), S. marcescens (ATCC 14041), P. aeruginosa (ATCC 9721), P. mirabilis (ATCC 33583) and E. coli (ATCC 10536). Galpinoside 5, hemerocalloside 3 and curculigoside C 2 are the other active compounds in Hypoxis plant.

Burns injuries induce a state of immunodepression that predisposes to a bacterial infectious complication that leads to several comorbid diseases and high mortality rate. Previous studies about anti-inflammatory, antimicrobial and antioxidant properties of Aloe vera (L.) Burm., Calendula officinalis L.and Matricaria recutita L. are acknowledge by antimicrobial effects. Previous studies about anti-inflammatory, antimicrobial and antioxidant properties of Aloe vera (L.) Burm., Calendula officinalis L. and Matricaria recutita L. are knowledge by antimicrobial effects. Bacterial cellulose membrane (nature BCM) is a potential carrier as a drug delivery system in the wound and burn treatment. The present study aimed to evaluate the antibacterial activity of extracts of A. vera, C. officinalis, and M. recutita incorporated in BCM against bacterial strains commonly present in wound and burns. The agar-dilution susceptibility testing was used to determine the minimum inhibitory concentration (MIC) for S. aureus, E. coli, and P. aeruginosa. The standardized extracts of A. vera, M. recutita, and C. officinalis were, respectively, used at 3.25% of total polysaccharides, 1% of apigenin 7-O-glucoside and 0.084% of total flavonoids expressed in quercetin. The BCM incorporated with A. vera extract was efficient to prevent the growth of P. aeruginosa and S. aureus. BCM loaded with C. officinalis inhibited the growth of S. aureus. The BCM loaded with A. vera and C. officinalis extract showed better antibacterial activities against P. aeruginosa and S. aureus and, consequently, properties to prevent infectious disease in the wound or burn caused by these bacteria.

Aim: This study calculated the effects on serum phosphorus (P) levels, after treatment with either of 2 drugs: the erythropoietin (Epo) and the antioxidant lazaroid (L) drug U-74389G. The calculation was based on the results of 2 preliminary studies, each one of which estimated the certain influence, after the respective drug usage in an induced ischemia reperfusion (IR) animal experiment. Materials and methods: The 2 main experimental endpoints at which the serum P levels were evaluated was the 60th reperfusion min (for the groups A, C and E) and the 120th reperfusion min (for the groups B, D and F). Specially, the groups A and B were processed without drugs, the groups C and D after Epo administration; whereas the groups E and F after the L administration. Results: The first preliminary study of Epo presented a non significant hyperphosphoremic effect by 2.46% + 2.02% (p - value = 0.2168). However, the second preliminary study of U-74389G presented a non significant hypophosphoremic effect by 1.09% + 2.01% (p - value = 0.5771). These 2 studies were co-evaluated since they came from the same experimental setting. The outcome of the co-evaluation was that L is at least 0.4455128-fold [0.4445589 - 0.4464687] more hypophosphoremic than Epo (p - value = 0.0000). Conclusions: The anti-oxidant capacities of U-74389G ascribe at least 0.4455128-fold [0.4445589 - 0.4464687] more effects than Epo (p - value = 0.0000). 

The biological changes caused by oxidative stress (OS) are known to be involved in the etiology of neurodegenerative disorders, including Alzheimer’s disease, amyotrophic lateral sclerosis, Huntington’s disease, and Parkinson’s disease. The brain is particularly vulnerable to OS due to its high lipid content and extensive consumption of oxygen. OS processes, particularly the excessive production of reactive oxygen species (ROS), play a critical role in how neurodegenerative disorders develop. This is evidenced by in vivo studies investigating various biomolecules related to OS, such as products of lipid and DNA oxidation. Accordingly, ROS can also cause oxidative-related damage in neurodegenerative disorders, including dopamine auto-oxidation, mitochondrial dysfunction, glial cell activation, α-synuclein aggregation, excessive free iron, and changes in calcium signaling. Furthermore, excessive levels of cellular oxidants reduce antioxidant defenses, which in turn propagate the cycle of OS. As such, it is increasingly important to determine the linkage between a high intake of antioxidants through dietary interventions and a lower risk of developing neurodegenerative diseases. Indeed, in addition to modulating the immune system, optimal nutritional status is capable of changing various processes of neuroinflammation known to be involved in the pathogenesis of neurodegeneration. Accordingly, a better understanding of the role ROS plays in the etiology of neurodegeneration is needed, along with the identification of dietary interventions that may lead to improved therapeutic strategies for both the treatment and prevention of neurodegenerative disorders. Therefore, this review presents a comprehensive summary of the role of ROS in the pathogenesis of neurodegenerative disorders. In addition, nutrients believed to be useful for mitigating and counteracting ROS are discussed. 

The objective was to assess the antioxidant effect of melatonin (MLT) on liver and lung tissues of animals with bile duct ligation (BDL)-induced hepato-pulmonary syndrome (HPS). A model of BDL-induced biliary cirrhosis was used in male Wistar rats. Results suggest that MLT has an antioxidant effect on liver and lung tissues in animals with BDL-induced HPS by higher activity of antioxidant enzymes in the group HPS treated with MLT and the histological analysis of lung parenchyma showing decreased damage in this same group, including other analysis described below.

Air pollution exposure is among the most prevalent reasons for environmentally-induced oxidative stress and inflammation, both of which are implicated in the central nervous system (CNS) diseases. The CNS has emerged as an important target for adverse health effects of exposure to air pollutants, where it can cause neurological and neurodevelopmental disorders. Air pollution includes various components of gases, particulate matter (PM), ultrafine particulate (UFPs), metals, and organic compounds. An important source of PM and UFPM in the ambient air is associated with air pollution-related trafficking, and primarily diesel exhaust particles (DEPs). Controlled animal studies and epidemiological studies show that exposure to air pollution, and in particular urban air pollution or DEPs, may lead to neurotoxicity. In specific, exposure to air pollutants as an important factor may be in neurodevelopmental disorders (eg Autism) and neurological disorders (eg.., Alzheimer’s Disease (AD)). The most noticeable effects of exposure to air pollutants in animals and humans are oxidative stress and neurodegeneration. Studies in rats exposed to DEPs showed microglial activity, increased lipid peroxidation, and neuronal accumulation in various areas of the brain, especially the olfactory bulb (OB) and the hippocampus (HI). Disorders of adult neurogenesis were also found. In most cases, the effects of DEP are more pronounced in male mice, probably due to lower antioxidant capacity due to less expression of paraoxonase 2.

Introduction: Oxidative stress is a phenomenon induced by an imbalance between production and the biological system's ability to readily detoxify oxygen reactive species (ROS) in cells. It has been shown that grape juice can reduce oxidative stress due to the presence of polyphenols. The aim of this study was to evaluate the effect of fresh red grape juice and grape fermentative product on oxidative stress in human erythrocytes.Methods: 5 ml of blood from 125 healthy individuals as control group collected in EDTA containing tubes. To perform biochemical assays, erythrocytes were incubated at 37 ºC for different times including 4, 24, 48, and 72 hours in the presence or absence of grape juice and grape red wine in amounts of 5 ml. Results: Grape juice and grape red wine reduced lipid peroxidation and increase of thiol groups, and total antioxidant capacity after 24 hours of treatment (p < 0.05). Also, the activity of catalase enzyme was increased 4 and 24 hours after treatment with red wine and grape juice, respectively. Conclusion: Grape juice and grape fermentative product may improve the antioxidant power of erythrocytes. This may lead to reducing the risk of free-radical damage and chronic diseases. However, more research with a higher number of samples is necessary to confirm the antioxidant effect of grape juice and red wine on human erythrocytes.

The commonest etiology of acute kidney injury (AKI) is Sepsis that results in an escalation of morbidity and mortality in the hospital intensive care units. Existentially, the therapy of septic AKI rather than being definitive or curative is just supportive, without tackling the pathophysiology. Usually, Sepsis gets correlated with systemic inflammation, along with the escalated generation of Reactive oxygen species (ROS), in particular superoxide. Simultaneously liberation of nitric oxide (NO) subsequently reacts with the superoxide, thus, resulting in the generation of reactive nitrogen species (RNS), that is mostly peroxynitrite. This sepsis stimulated generation of ROS in addition to RNS might cause a reduction in the bioavailability of NO that modulates microcirculation aberrations, localized tissue hypoxia as well as mitochondrial impairment, thus starting a vicious cycle of cellular damage which results in AKI. Here we conducted a systematic review utilizing search engine PubMed, Google scholar; Web of science; Embase; Cochrane review library utilizing the MeSH terms like septic AKI; ROS; inducible nitric oxide synthase (iNOS); nicotinamide adenine nucleotide phosphate(NADPH)oxidase complex; Oxidative stress; Renal medullary hypoxia; Hypoxia inducible factor1; hypoxia responsive enhancer A; mitochondrial impairment; Intrarenal oxygenation; urinary oxygenation; erythropoietin gene; RRT; NAC; Vitamin C from 1950 to 2021 till date. We found a total of 6500 articles out of which we selected 110 articles for this review. No meta-analysis was done. Thus here we detail the different sources of ROS, at the tie of sepsis, besides their pathophysiological crosstalk with the immune system, microcirculation as well as mitochondria that can result in the generation of AKI. Furthermore, we detail the therapeutic utility of N-acetylcysteine (NAC), besides the reasons for its success in ovine as well as porcine models of AKI. Moreover, we discuss preclinical along with clinical for evaluation of Vitamin C’s antioxidant effects as well as pleiotropic effects as a stress hormone that might aid in abrogation of septic AKI.

Aim: Accumulating data imply that glaucoma may represent a neurodegenerative disorder affecting the entire visual system. We evaluated retrobulbar glaucomatous damage with favorable techniques for 1.5T diffusion-tensor magnetic resonance imaging and we compared those techniques with clinical data in a large case series. Material and methods: This Cross-sectional study included 130 eyes of 65 patients with primary open-angle glaucoma. Patients with no known ocular or systemic concomitant disorders, neurological diseases, previous glaucoma surgeries, or antioxidant usage were selected. A decrease in thickness and deterioration in the optic nerve diffusion of severely glaucomatous eyes of patients with asymmetrical involvement was observed in optic nerve tractography. Optical coherence tomography and visual field results of the subjects were recorded. Glaucoma analysis with optical coherence tomography and standard automated perimetry results of the subjects were recorded. Diffusion-tensor magnetic resonance imaging analysis of optic nerves and radiations were performed, computing fractional anisotropy, apparent diffusion coefficient, axial diffusivity, and radial diffusivity. Correlation between the diffusion-tensor magnetic resonance imaging and clinical eye parameters of glaucomatous neurodegeneration were statistically evaluated. Results: The correlations between diffusion parameters and age were highly significant. Statistically significant correlations were found between ganglion cell complex and apparent diffusion coefficient, axial and radial diffusivities of optic nerves. Conclusion: Eye-brain connection in glaucoma can be evaluated with routine clinical instruments. Our study also revealed a limited correlation of retrobulbar glaucomatous neurodegeneration with ophthalmic damage. A better understanding of retrobulbar damage will enable us to develop more efficient strategies and a more accurate understanding of glaucoma.
