Cuschieri A, Camilleri E, Blundell R. Cerebroprotective effects of Moringa oleifera derivatives extracts against MCAO ischemic stroke: A systematic review and meta-analysis. Heliyon 2023; 9:e16622. [PMID: 37303567 PMCID: PMC10248124 DOI: 10.1016/j.heliyon.2023.e16622] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 05/04/2023] [Accepted: 05/22/2023] [Indexed: 06/13/2023] Open
Abstract
Moringa oleifera (MO), has been studied extensively, and has numerous medicinal and socioeconomic benefits. Emerging research has investigated the efficacy of MO extract and/or its phytochemical derivatives against ischemic stroke in-vivo. To date, no studies comprehensively reviewing the effects of MO extract and/or its phytochemical derivatives against ischemic stroke have been published. A systematic review and meta-analysis was conducted to assess the effects of MO extract and/or its phytochemical derivatives against focal ischemic stroke, modeled in-vivo. Compared with control groups, significant reduction in infarct volume and malondialdehyde levels, and signficant increase in antioxidant enzymes superoxide dismutase, glutathione peroxidase and catalase. The primary mechanism of action of MO extract and its phytochemical derivatives which confers neuroprotection is reduction in oxidative stress by increasing antioxidant enzymes. On the whole, the present systematic review critically assessed evidence which demonstrated that MO extract may confer protective effect on experimental ischemic stroke. Although effect size may have been overestimated due to the limited number of included studies, small sample sizes and possible publication bias, results generated in this meta-analysis dmeonstrate that MO extract may be a promising neuroprotective agent against human ischemic stroke.

Metabolites of Moringa oleifera Activate Physio-Biochemical Pathways for an Accelerated Functional Recovery after Sciatic Nerve Crush Injury in Mice. Metabolites 2022; 12:metabo12121242. [PMID: 36557280 PMCID: PMC9788086 DOI: 10.3390/metabo12121242] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Revised: 12/03/2022] [Accepted: 12/07/2022] [Indexed: 12/13/2022] Open
Abstract
In this study, the functional metabolites of Moringa oleifera (MO) were screened to evaluate their possible role in accelerated functional retrieval after peripheral nerve injury (PNI). MO leaves were used for extract preparation using solvents of different polarities. Each dry extract was uniformly mixed in rodents' chow and supplemented daily at a dose rate of 2 g/kg body weight from the day of nerve crush until the completion of the trial. The sciatic functional index (SFI) and muscle grip strength were performed to assess the recovery of motor functions, whereas the hotplate test was performed to measure the regain of sensory functions. An optimal level of oxidative stress and a controlled glycemic level mediates a number of physio-biochemical pathways for the smooth progression of the regeneration process. Therefore, total oxidant status (TOS), total antioxidant capacity (TAC) and glycemic levels were analyzed in metabolite-enriched extract-treated groups compared to the control. The supplementation of polar extracts demonstrated a significantly high potential to induce the retrieval of sensory and motor functions. Further, they were highly effective in controlling oxidative stress, facilitating accelerated nerve generation. This study has highlighted MO as a sustainable source of nutritive metabolites and a valuable target for drug development.

[PMID: 36206551 DOI: 10.1111/jfbc.14451] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Revised: 09/08/2022] [Accepted: 09/15/2022] [Indexed: 01/14/2023]
Abstract
Moringa oleifera is a traditional Indian herb belonging to the Moringaceae family, it is commonly known as the horse-radish tree, drumstick, or sahajna. In developing countries, Moringa is used as feed for both humans and animals due to its well-known antioxidant, anti-inflammatory, and anti-apoptotic properties owing to its several phytoconstituents including β-carotene, quercetin, kaempferol, ascorbic acid, flavonoids, phenolic acid, rhamnose, glycosylates, glucomoringin, and isothiocyanates. These constituents help to maintain the brain antioxidant enzyme levels, mitochondrial functions, and neurogenesis, showing neuroprotective effects in several neurodegenerative disorders including Parkinson's Disease, Alzheimer's Disease, Huntington's Disease, and Amyotrophic lateral sclerosis. This review discusses various phytoconstituent of moringa and their therapeutic potential in various neurological disorders. Additionally, we also concise the safety and toxicity profile, of different molecular pathways involved in the neuroprotective effect of M. oleifera including M. oleifera nanoparticles for better therapeutic value. PRACTICAL APPLICATIONS: Several clinical and preclinical studies on Moringa oleifera have been conducted, and the outcomes indicate moringa could be used in the treatment of brain disorders. As a result, we conclude that moringa and its nanoformulations could be employed to treat neurological problems. In the future, M. oleifera phytoconstituents could be evaluated against specific signaling pathways, which could aid researchers in discovering their mechanism of action. Furthermore, the use of moringa as a nutraceutical owing to its myriad pharmacological potential will go a long way in boosting the economy of countries that grow moringa on a large scale.

Abstract
Neurological disorders are the foremost occurring diseases across the globe resulting in progressive dysfunction, loss of neuronal structure ultimately cell death. Therefore, attention has been drawn toward the natural resources for the search of neuroprotective agents. Plant-based food bioactives have emerged as potential neuroprotective agents for the treatment of neurodegenerative disorders. This comprehensive review primarily focuses on various plant food bioactive, mechanisms, therapeutic targets, in vitro and in vivo studies in the treatment of neurological disorders to explore whether they are boon or bane for neurological disorders. In addition, the clinical perspective of plant food bioactives in neurological disorders are also highlighted. Scientific evidences point toward the enormous therapeutic efficacy of plant food bioactives in the prevention or treatment of neurological disorders. Nevertheless, identification of food bioactive components accountable for the neuroprotective effects, mechanism, clinical trials, and consolidation of information flow are warranted. Plant food bioactives primarily act by mediating through various pathways including oxidative stress, neuroinflammation, apoptosis, excitotoxicity, specific proteins, mitochondrial dysfunction, and reversing neurodegeneration and can be used for the prevention and therapy of neurodegenerative disorders. In conclusion, the plant based food bioactives are boon for neurological disorders.

Methanolic Moringa oleifera leaf extract protects against epithelial barrier damage and enteric bacterial translocation in intestinal I/R: Possible role of caspase 3. Front Pharmacol 2022; 13:989023. [PMID: 36210817 PMCID: PMC9546449 DOI: 10.3389/fphar.2022.989023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Accepted: 09/05/2022] [Indexed: 11/25/2022] Open
Abstract
Background: Activation of caspase 3 has been implicated in the pathogenesis of I/R injury in various organs, but there is a paucity of data on its role in IIRI. Also, no reports were found on the beneficial role of methanolic Moringa oleifera leaf extract (MMOLE) in IIRI. This study investigated the involvement of caspase 3 in IIRI, and the impact of MMOLE in IIRI. Methods: Male Wistar rats were randomized into five groups; the sham-operated group that was sham-operated and received 0.5 ml of distilled water for 7 days prior to sham surgery, and the IIRI, febuxostat (FEB) +IIRI, low dose MMOLE (LDMO)+IIRI, and high dose MMOLE (HDMO)+IIRI groups that underwent I/R and also received 0.5 ml of distilled water, 10 mg/kg of febuxostat, 200 mg/kg of MMOLE, and 400 mg/kg of MMOLE respectively for 7 days prior to I/R. Markers of hepatic function, oxidative stress, and inflammation as well as enteric bacterial translocation and histoarchitecture integrity of intestinal and hepatic tissues were evaluated. The bioactive components of MMOLE were also determined by GC-MS. Results: As revealed by GC-MS, the active bioactive components of MMOLE were thiosemicarbazone, hydrazine, 1,3-dioxolane, octanoic acid, 1,3-benzenediamine, 9-octadecenoic acid, oleic acid, nonadecanoic acid, 3-undecanone, phosphonic acid, and cyclopentanecarboxylic acid. MMOLE alleviated IIRI-induced rise in intestinal and hepatic injury markers, malondialdehyde, TNF-α, IL-6, and myeloperoxidase activities. MMOLE improved IIRI-induced suppression of reduced glutathione, thiol and non-thiol proteins, and superoxide dismutase, catalase and glutathione peroxidase activities. These were associated with suppression of IIRI-induced caspase 3 activity and bacterial translocation. Histopathological evaluation revealed that MMOLE attenuated IIRI-induced alterations in intestinal and hepatic histoarchitecture integrity. MMOLE also militated against increased absolute and relative intestinal and hepatic weight, intestinal and hepatic injuries, epithelial mucosal barrier dysfunction, and enteric bacterial translocation associated with IIRI by downregulating oxidative stress-mediated activation of caspase 3. Conclusion: IIRI is associated with a rise in caspase 3 activity. Also, MMOLE confers protection against IIRI, possibly due to its constituent bioactive molecules, especially hydrazine, 9-octadecenoic acid, 1,3-dioxolane, oleic acid, and nonadecanoic acid.

Front Nutr 2022; 9:799127. [PMID: 35299766 PMCID: PMC8922057 DOI: 10.3389/fnut.2022.799127] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Accepted: 01/26/2022] [Indexed: 12/02/2022] Open
Abstract
Background The cognitive deficit has frequently been found in the elderly population. Several studies have shown that every single part of Moringa oleifera, including leaves, roots, and seeds, has abundant micronutrients, such as flavonoids, which improve the neurobehavioral capacity. However, herb parts that display optimal neuropharmacological properties remain unknown. Objective We investigate whether M. oleifera seed oil (MOO) or aqueous M. oleifera leaves extracts (MOEs) may ameliorate memory impairment in mice induced with scopolamine (Sco). Additionally, the phytochemical analyses of those two independent formulations were analyzed. Methods In this study, 2 ml/kg body weight (BW) of MOO and 500 mg/kg BW of MOE were orally administered to the mice for 28 days, followed by intraperitoneal injection of Sco (1 mg/kg) at the day 22–28 to induce cognitive impairment in those mice. Results The Sco group showed memory retention impairment represented by the Y-maze and novel object recognition tests, significant enhancement of acetylcholine esterase (AChE) activity in hippocampus tissue (p < 0.0001), and increased the level of total antioxidant capacity (TAOC) in serum. Interestingly, the Sco-induced memory defect was improved and completely blunted the AChE exacerbation in Sco+MOO-treated mice (p < 0.0001), although the TAOC level was comparable among the groups. Mechanistically, both tropomyosin receptor kinase B (TrkB), as a brain-derived neurotrophic factor-receptor, and nuclear factor-kappa-light-chain-enhancer of activated B cells (NF-κB) protein expressions were enhanced with the hippocampus isolated from the Sco group. Nonetheless, pretreatment with MOO only, but not with MOE, ameliorated the enhanced protein expression levels of TrkB and NF-κB (p < 0.05 and p = 0.09, respectively). Conclusion Our data reveal that MOO is preferable to MOE as a neuroprotective as evidenced by improving memory impairment. This effect, at least in part, through inhibiting the AChE and NF-κB activities and modulating the TrkB expression level.

Abstract
Moringa oleifera leaves have been widely used for the treatment of inflammation, diabetes, high blood pressure, and other diseases, due to being rich in polyphenols. The main objective of this work was to largely separate the main polyphenols from Moringa oleifera leaves using the technique of high-speed counter-current chromatography (HSCCC). The phenolic composition in Moringa oleifera leaves was first analyzed qualitatively and quantitatively by UPLC-Q-Exactive Orbitrap/MS and UPLC-QqQ/MS, respectively, indicating that quercetin and kaempferol derivatives, phenolic acid and apigenin are the main polyphenols in Moringa oleifera leaves, with quercetin and kaempferol derivatives predominating. Furthermore, the conditions of HSCCC for large-scale separation of polyphenols from Moringa oleifera leaves were optimized, which included the selection of the solvent system, flow rate and the sample load. Only by one-step HSCCC separation (within 120 min) under the optimized conditions, six quercetin and kaempferol derivatives, a phenolic acid and an apigenin could be individually isolated at a large scale (yield from 10% to 98%), each of which possessed high purity. Finally, the isolated polyphenols and phenolic extract from Moringa oleifera leaves (MLPE) were verified to have strong neuroprotective activities against H2O2-induced oxidative stress in PC-12 cells, suggesting that these compounds would contribute to the main beneficial effects of Moringa oleifera leaves.

Abstract
Neurodegenerative diseases (NDDs) and cardiovascular diseases (CVDs) are illnesses that affect the nervous system and heart, all of which are vital to the human body. To maintain health of the human body, vegetable diets serve as a preventive approach and particularly Brassica vegetables have been associated with lower risks of chronic diseases, especially NDDs and CVDs. Interestingly, glucosinolates (GLs) and isothiocyanates (ITCs) are phytochemicals that are mostly found in the Cruciferae family and they have been largely documented as antioxidants contributing to both cardio- and neuroprotective effects. The hydrolytic breakdown of GLs into ITCs such as sulforaphane (SFN), phenylethyl ITC (PEITC), moringin (MG), erucin (ER), and allyl ITC (AITC) has been recognized to exert significant effects with regards to cardio- and neuroprotection. From past in vivo and/or in vitro studies, those phytochemicals have displayed the ability to mitigate the adverse effects of reactive oxidation species (ROS), inflammation, and apoptosis, which are the primary causes of CVDs and NDDs. This review focuses on the protective effects of those GL-derived ITCs, featuring their beneficial effects and the mechanisms behind those effects in CVDs and NDDs.

Abstract
BACKGROUND Moringa oleifera Lam (MO) is native to India and is a cash crop widely cultivated in tropical and sub-tropical areas. The health improving properties of MO has been studied from a long time ago for the numerous phenolic compounds, including vitamins, flavonoids, phenolic acids, isothiocyanates, tannins and saponins, which are present in considerable amounts in the plant. A growing spectrum of therapeutic characteristics of MO leaves has been found and used in the remission or treatment of oxidative stress, liver disease, neurological disease, hyperglycemia and cancer. HYPOTHESIS This review focused on researches applying MO or MO leaf extract as a functional food or cure against various disease and cellular injuries. We believed it would help the discovery of therapeutic application of MO and understanding of MO phytochemistry. METHODS The data collected in this review were extracted from researches indexed in Web of Science, google scholar, PubMed, Science Direct and Scopus to find out health benefits and biological activities of MO leaves polyphenols. The studies reporting mechanistic route of phenolic compounds of MO leaves were also considered in the present study. RESULTS It has been reported that polyphenols of MO leaf have protective characteristics against neurodegenerative disorders through reducing DNA damage, activation of AchE activity and inhibition of caspase-3 activity. It has been reported that, they protected the kidney from damage caused by melamine through suppressed the pro-inflammatory cytokine, metallopeptidase inhibitor 1 (TIMP-1), and kidney injury molecule 1 (KIM-1). Similarly, methanol extract of MO leaves has low hypoglycemic attributes and attenuate the risk of diabetes caused by alloxan by enhancing lipid metabolism and stimulating insulin release, glucose uptake, and glycogen synthesis. In addition, MO leaves are becoming the best phytomedicine to reduce hypertension, which are naturally known as angiotensin-1converting enzyme (ACE), acetylcholinesterase, arginase and phosphodiesterase 5 (PDE5) inhibitors. CONCLUSION MO leaves extract as a health promoting food additives for human and animals due to its great protective effect against many diseases and the widely persistent environmental toxins which disrupted cellular metabolic function. More studies are required to use the phenolic compounds of MO leaves to develop and produce drugs for controlling and treatment of various diseases.

Abstract
Nitraria tangutorun Bobr. has been used for thousands of years as a native folk medicine to alleviate dizziness and neurasthenia due to oxygen. In our previous study, natural antioxidant components (namely, NJBE) were isolated from industrial N. tangutorun Bobr. juice byproducts (NJBE) from the Qinghai-Tibet plateau. The current investigation assessed the effects of NJBE on ischemic stroke in mice and the potential mechanisms. C57BL/6 mice received NJBE (25, 50, or 100 mg/Kg) by gavage for 14 days and then stroke was induced by the middle cerebral artery occlusion (MCAO) model, followed by reperfusion for 72 h. The evaluation of brain infarct size, behavioral tests, and functional assessments was conducted to assess the effects of NJBE after MCAO. Our results suggested that NJBE significantly decreases infarct size, improves neurological deficits, as well as reduces the number of GFAP+ and Iba-1+ cells after MCAO. NJBE inhibited nitric oxide and malondialdehyde production in the ischemic brain. Meanwhile, it attenuated the expressions of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). Also, NJBE significantly attenuated the expression levels of proinflammatory indicators, including TNF-α, IL-1β, IL-6, and IL-12. This process was accompanied by the downregulation of TLR4, TRAF6, pIκB/pIκB, and MMP9 expression and the upregulation of claudin-5 expression. NJBE induced improvements in brain injury. The neuroprotective effect of NJBE provides evidence for its potential application in stroke treatment.

Abstract
The present study was focused to isolate the bioactive compounds present in the leaves of Moringa oleifera which contains a high nutritional value. Furthermore, the research was aimed to evaluate the antioxidant, anti-aging, and anti-neurodegenerative properties of M. oleifera using the experimental model Caenorhabditis elegans. The separation of compounds from the crude extract and its identification was carried out through TLC, Column chromatography, UV absorption spectroscopy, and GC-MS. The compounds identified in most abundant fraction of column chromatography were [Phenol-2,4-bis(1,1-dimethylethyl)- phosphite (3:1)] and Tetratetracontane. The result suggests that the leaves extracts and column fraction were able to significantly extend the life span of the N2 wild-type strain of C. elegans. The most potent life span extending effect was displayed by the dichloromethane extract of leaves which was 21.73 ± 0.142 days compared to the control (16.55 ± 0.02 days). It could also extend the health span through improved physiological functions such as pharyngeal pumping, body bending, and reversal frequency with increased age. The treated worms were also exhibited improved resistance to thermal stress, oxidative stress, and reduced intracellular ROS accumulation. Moreover, the leaves extract could elicit neuroprotection as it could delay the paralysis in the transgenic strain of C. elegans 'CL4176' integrated with Aβ. Interestingly, The RNAi experiment demonstrated that the extended life span under the treatment of extracts and the compound was daf-16 dependent. In transgenic C. elegans TJ356, the DAF-16 transcription factor was localized in the nucleus under the stress conditions, further supported the involvement of the daf-16 gene in longevity. Overall, the study suggests the potential of M. oleifera as a dietary supplement and alternative medicine to defend against oxidative stress and aging.

Abstract
BACKGROUND Moringa oleifera is known to exhibit protection against oxidative damage due to its rich content of compounds with antioxidant activity. This study investigated the protective effect of the methanol extract of Moringa oleifera (MO) in a rat model of renal ischemia-reperfusion (IR) injury. METHODS Forty two wistar rats were randomly assigned to six groups of seven rats each, as follows: A, control group; B, sham-operated group; C, IR group; D, IR + low dose (200 mg/kg) MO; E, IR + high dose (400 mg/kg) MO and F, IR + Vitamin C (200 mg/kg). Unilateral ischaemia was induced by occluding the left renal artery for 45 minutes followed by reperfusion up to 24 hours. RESULTS Moringa oleifera significantly (p<0.05) ameliorated IR-induced increases in malondialdehyde (MDA), protein carbonyls (PC) and advanced oxidation protein products (AOPP), while also decreasing serum BUN and Creatinine levels. Moreover, the low dose of MO caused reductions in renal NO and H2O2 levels, while increasing renal GPx and GST activities. Histopathology revealed marked improvement of tissue alterations induced by IR with both doses of MO. CONCLUSION Overall, the methanol extract of M. oleifera effectively attenuated the deleterious effects of renal IR via alleviation of tissue oxidative stress.

Abstract
Moringa oleifera L. from the Moringaceae family is a perennial tree widely cultivated in many tropic regions and easily grown even in adverse conditions. M. oleifera is also known as the miracle tree, which for centuries has been indicated for traditional medicine. With no reports of side effects, in doses achievable by ingestion, different parts of M. oleifera is used to treat several conditions, such as malnutrition, diabetes, blindness, anemia, hypertension, stress, depression, skin, arthritis, joints and kidney stones disorders. This plant also showed capacity of helping in maintenance of the cardiovascular system health, blood-glucose levels and providing anti-oxidant, anti-inflammatory and anti-cancer activity as well as the regulation of urinary tract and lactation in nursing women. The seed and leaves powder has water purification properties through flocculation. It also supplements the food in the human diet and in the fortification of livestock feed, especially in developing countries. So, M. oleifera properties have also been applied to cosmetic and byproducts industries due to the high nutritive and protective properties of its seed oil. According to the holistic or traditional medicine, M. oleifera has very relevant therapeutic properties and applications depending on the constitution, somatic and psychological needs of patients. It is usually referred as a natural product that can treat different physical and psychological health aspects, offering an energetic action and structural rebuilder of the body and promoting emotions of highly positive attitudes towards life. The high and specific immunological potential of M. oleifera leads us to suggest an in-depth study to assess the hypothesis of conferring a supportive effect against Covid-19 disease.

Abstract
Moringa oleifera (MOI), an edible plant in the family of Moringaceae, has been used as food and medicine in many Asian countries. MOI exhibits neuroprotective, antioxidant, anti-inflammatory, and hypoglycemic functions. However, whether MOI seeds play a significant role in ischemic heart diseases has not been investigated. In this study, we found MOI seeds could improve the 28-day survival rate and the cardiac functions of myocardial infarction (MI) mice, with significantly increased ejection fraction and fractional shortening by day 28 post-MI. Correspondingly, the infarctional areas of heart were markedly decreased. Mechanistically, MOI seeds inhibited MI-induced apoptosis and repressed the degree of cardiac fibrosis. Further mechanistic studies indicated cardioprotective the effects of MOI seeds mainly via the suppression of oxidative and nitrosative stress. Taken together, our work suggested a beneficial role of MOI seeds in MI-induced myocardial damage and cardiac remodeling by suppressing cardiomyocyte apoptosis and reducing collagen production, highlighting a promising therapeutic strategy for MI.

Abstract
Vanadium, a transition series metal released during some industrial activities, induces oxidative stress and lipid peroxidation. Ameliorative effect of a pure compound from the methanolic extract of Moringa oleifera leaves, code-named MIMO2, in 14-day old mice administered with vanadium (as sodium metavanadate 3 mg/kg) for 2 weeks was assessed. Results from body weight monitoring, muscular strength, and open field showed slight reduction in body weight and locomotion deficit in vanadium-exposed mice, ameliorated with MIMO2 co-administration. Degeneration of the Purkinje cell layer and neuronal death in the hippocampal CA1 region were observed in vanadium-exposed mice and both appeared significantly reduced with MIMO2 co-administration. Demyelination involving the midline of the corpus callosum, somatosensory and retrosplenial cortices was also reduced with MIMO2. Microglia activation and astrogliosis observed through immunohistochemistry were also alleviated. Immunohistochemistry for myelin, axons and oligodendrocyte lineage cells were also carried out and showed that in vanadium-treated mice brains, oligodendrocyte progenitor cells increased NG2 immunolabelling with hypertrophy and bushy, ramified appearance of their processes. MIMO2 displayed ameliorative and antioxidative effects in vanadium-induced neurotoxicity in experimental murine species. This is likely the first time MIMO2 is being used in vivo in an animal model.

Abstract
BACKGROUND Malaria is a worldwide problem that affects millions of people yearly. In rural areas where anti-malarial drugs are not easily accessible, many people use herbal treatments, such as Moringa oleifera, to treat a variety of diseases and ailments including malaria. While Moringa is reported to possess potent and curative anti-malarial properties, previous studies have mostly been restricted to assessment of parasitaemia. In this study, the effect of Moringa on malaria immunity in a murine model was investigated. METHODS Using a high dose (60 mg/mouse) for a short time (7 days) or low dose Moringa (30 mg/mouse) for a longer time (3 weeks), cytokine production, and Tbet expression by effector CD4+ T cells (Teff) were determined. Mice were also treated with Moringa after infection (curatively) or before infection (prophylactically) to determine the effect of the plant extract on parasitaemia and immunity. Given that Moringa also possess many nutritional benefits, the contribution of Moringa on malnourished malaria infected mice was determined. Malnutrition was induced by limiting access to food to only 4 h a day for 4 weeks, while control mice had unlimited access to mouse laboratory chow. All data was collected by flow cytometry and analysed using one-Way ANOVA or two tailed Student's t test. RESULTS Moringa-treated mice had increased numbers of effector CD4+ T cells accompanied by an increase in Tbet expression compared to control untreated mice. Mice that were treated with Moringa curatively also exhibited increased effector CD4+ T cell numbers, IFN-gamma and TNF secretion. Interestingly, the mice that were treated prophylactically had significantly higher Tbet expression. In the absence of adaptive immunity, high parasitaemia was observed in the RAG1 knockout mice. The food limited mice (malnourished) had reduced numbers of CD4+ T cells, TNF proportions, and significantly greater Tbet expression compared to the control group. Supplementation with Moringa in the limited group slightly restored CD4+ T cell activation, IL-2, and IL-10 production. CONCLUSIONS Taken together, these data suggest that Moringa treatment leads to increased CD4+ T cell activation, Th1 differentiation and production of pro-inflammatory cytokines after malaria infection. Thus, Moringa may be immunologically useful in the treatment of malaria and malnutrition. Further investigations are required to identify the active components in Moringa.

Abstract
OBJECTIVES Oxidative stress and inflammation have a critical role in the pathogenesis of ischaemic stroke. Alpha-pinene is a monoterpenoid molecule with anti-inflammatory and antioxidant properties. The nobility of the present study was to evaluate the neuroprotective effect of α-pinene in ischaemic stroke. METHODS Ischaemic stroke was induced by transient middle cerebral artery occlusion followed by 24 h reperfusion in male Wistar rats. Alpha-pinene (25, 50 and 100 mg/kg, i.p.) was administered in the beginning of reperfusion. Then, the neurobehavioural function, infarct volume, brain oedema, antioxidant enzyme activity and the concentration of malondialdehyde (MDA), nitric oxide (NO) and interleukin-6 (IL-6) were evaluated by different methods in the brain. KEY FINDINGS Alpha-pinene (50 and 100 mg/kg) elicited a significant decrease in the brain oedema and infarct size as well as an improvement in the neurobehavioural function. Besides, α-pinene (100 mg/kg) restored the function of superoxide dismutase, catalase and glutathione peroxidase and reduced the concentration of MDA, NO and IL-6 in the hippocampus, cortex and striatum. CONCLUSIONS It was ultimately attainted that α-pinene exerts neuroprotective effect in ischaemic stroke in rat through the restoration of antioxidant enzymes activity, attenuation of lipid peroxidation and reduction of inflammation in the ischaemic brains.

Abstract
Alzheimer’s disease (AD) is multifactorial with unclear etiopathology. Due to the complexity of AD, many attempted single therapy treatments, like Aβ immunization, have generally failed. Therefore, there is a need for drugs with multiple benefits. Naturally occurring phytochemicals with neuroprotective, anti-amyloidogenic, antioxidative, and anti-inflammatory properties could be a possible way out. In this study, the effect of Moringa oleifera (MO), a naturally occurring plant with high antioxidative, anti-inflammatory, and neuroprotective effects, was evaluated on hyperhomocysteinemia (HHcy) induced AD-like pathology in rats. Homocysteine (Hcy) injection for 14 days was used to induce AD-like pathology. Simultaneous MO extract gavage followed the injection as a preventive treatment or, after injection completion, MO gavage was performed for another 14 days as a curative treatment. MO was found to not only prevent but also rescue the oxidative stress and cognitive impairments induced by Hcy treatment. Moreover, MO recovered the decreased synaptic proteins PSD93, PSD95, Synapsin 1 and Synaptophysin, and improved neurodegeneration. Interestingly, MO decreased the Hyc-induced tau hyperphosphorylation at different sites including S-199, T-231, S-396, and S-404, and at the same time decreased Aβ production through downregulation of BACE1. These effects in HHcy rats were accompanied by a decrease in calpain activity under MO treatment, supporting that calpain activation might be involved in AD pathogenesis in HHcy rats. Taken together, our data, for the first time, provided evidence that MO alleviates tau hyperphosphorylation and Aβ pathology in a HHcy AD rat model. This and previous other studies support MO as a good candidate for, and could provide new insights into, the treatment of AD and other tauopathies.

Abstract
BACKGROUND Few stroke patients have reported improvements after Ayurvedic massage. Unfortunately, there is a dearth of indexed literature to support the use of this in rehabilitation. OBJECTIVES To objectively measure the differences between patients with stroke who received Ayurvedic massage in addition to standard Physiotherapy (PT) versus those who received only standard PT. MATERIALS AND METHODS The study was a prospective case control study, retrospectively analysed. The setting was a tertiary level hospital with neuro-rehabilitation unit. Fifty-two patients undergoing acute inpatient rehabilitation were prospectively followed post stroke. They were self-selected one month from the event for Ayurvedic massage with regular PT or PT alone. Twenty five received Ayurvedic massage with PT and twenty seven received only PT. All participants completed treatment. Information related to age, gender, National Institute of Health Stroke Scale result, number of co-morbidities, and whether cases were deemed simple or complex were taken at baseline. All patients received 6 hours of physical therapy averaged over a week. Massage was delivered daily for a total of 10 sessions followed by steam application. RESULTS Patients were categorized as simple or complicated stroke based on events prior to rehabilitation. Both simple and complicated patients who received Ayurvedic massage had lower MAS and need for antispastic drugs, achieved standing with minimal assistance sooner, and had better locomotion at discharge. All these differences were significant. CONCLUSION Utilizing Ayurvedic massage in post stroke patients with flaccidity can promote faster standing with minimal assistance and lead to less need for antispastic drugs at discharge.

Muscle-derived autologous mitochondrial transplantation: A novel strategy for treating cerebral ischemic injury. Behav Brain Res 2018; 356:322-331.

Abstract
The available evidence showed that mitochondrial transfer by releasing the extracellular vesicles containing mitochondria from astrocytes to neurons exerted a neuroprotective effect after stroke. Whether extracellular mitochondrial replenishment could rescue the tissues from cerebral ischemic injury still needs to be explored completely. It was hypothesized that the augmentation of mitochondrial damage after cerebral ischemia could be resolved by timely replenishment of exogenous mitochondria. A stroke model of middle cerebral artery occlusion (MCAO) was used in this study to verify this hypothesis. This study found that the number of extracellular mitochondria increased in rat cerebrospinal fluid after MCAO, and a higher proportion of mitochondria were associated with good neurological outcomes. Following 90-min ischemia, autologously derived mitochondria (isolated from autologous pectoralis major) or vehicle alone was infused directly into the lateral ventricles, and the rats were allowed to recover for 4 weeks. A plenty of infused mitochondria were found to be distributed in the boundary and ischemic penumbra areas. Furthermore, the transplantation of mitochondria reduced cellular oxidative stress and apoptosis, attenuated reactive astrogliosis, and promoted neurogenesis after stroke. Moreover, the transplantation of mitochondria decreased brain infarct volume and reversed neurological deficits. The findings suggested that the delivery of mitochondria through the lateral ventricles resulted in their widespread distribution throughout the brain and exerted a neuroprotective effect after ischemia-reperfusion injury.

Abstract
This study evaluated Moringa oleifera extracts from two locations in Niger Delta for in vitro anti-cholinesterase and antioxidant activities. Methanolic, aqueous and ethanolic extracts of Moringa oleifera were evaluated for inhibition of acetylcholinesterase (AChE) activity, antioxidant properties, and total phenolic and flavonoid contents using standard procedures. M. oleifera extracts possessed significant and concentration dependent AChE inhibitory activity for methanolic, aqueous, and ethanolic extracts. For the most potent extracts, the percentage AChE inhibition/IC50 (µg/mL) values were Moringa oleifera root methanolic extracts (MORME): ~80%/0.00845; Moringa oleifera root ethanolic extract 1 (MOREE1): ~90%/0.0563; Moringa oleifera root ethanolic extract 2 (MOREE2): ~70%/0.00175; and Moringa oleifera bark ethanolic extract (MOBEE): ~70%/0.0173. The descending order of AChE inhibitory potency of plant parts were: root > bark > leaf > flowers > seed. All M. oleifera methanolic extracts at a concentration of 1000 µg/mL displayed significant (p < 0.05–0.001) DPPH radical scavenging activity, with values of ~20–50% of that of ascorbic acid. The total phenolic content and total flavonoid content (TPC/TFC) of MORME, Moringa Oju bark methanolic extract (MOBME), MOREE1, MOREE2 and Moringa leaf ethanolic leaf extract (MLEE) were (287/254), (212/113), (223/185), (203/343) and (201/102) mg gallic acid equivalents/g and quercetin equivalents/g, respectively. There was an inverse correlation between plant extract AChE inhibition and total phenolic (p < 0.0001) and total flavonoid contents (p < 0.0012). In summary, this study revealed 5 of 19 extracts of M. oleifera that have potent in vitro anti-cholinesterase and antioxidant activities.

Abstract
The sulfonylurea receptor 1 (SUR1)-regulated NCca-ATP channels were progressively upregulated and demonstrated unchecked opening in central nervous system (CNS) injury, which induced cerebral damage. Glibenclamide (GLI) can block NCca-ATP channels and consequently exert protective effects. Recent studies have found that GLI has antioxidative effects. In this study, we primarily explored the antioxidative effects of GLI in a rat model of intracerebral hemorrhage (ICH). We found that GLI could scavenge free radicals, reduce activated-caspase-3 expression, increase the Bcl-2/Bax ratio, inhibit apoptosis, and improve functional neurological outcomes in a rat model of ICH.

Abstract
Due to requirement of novel memory enhancer for menopausal women, this study aimed to determine safety and effect of the functional drink containing the extracts of purple corn cob and pandan leaves (PCP) on memory and brain changes in experimental menopause induced by bilateral ovariectomy (OVX). Acute toxicity of PCP was carried out in female Wistar rats. The results showed that LD50 was more than 2000 mg/kg BW. To determine the cognitive enhancing effect of PCP, OVX rats were orally treated with PCP at the doses of 20, 40, and 80 mg/kg BW for 28 days. The spatial memory was assessed every 7 days throughout the study period. At the end of the study, oxidative stress status, acetylcholinesterase (AChE) activity, monoamine oxidase (MAO) activity, neuronal density, and extracellular signal regulated protein kinase 1 and 2 (ERK1/2) signaling in hippocampus were measured. The improved spatial memory, ERK1/2 expression, and neuron density in dentate gyrus of hippocampus were observed in PCP-treated rats. In addition, a reduction of AChE activity was also observed. Unfortunately, no improved oxidative stress status was observed. Taken altogether, PCP exerts the memory-enhancing effect partly through the suppression of AChE and the increase in ERK signaling in the hippocampus.

Abstract
This study aimed to determine the protective effect of cashew nut-derived protein hydrolysate with high dietary fiber (AO) in cerebral ischemic rats induced by the occlusion of right middle cerebral artery (Rt.MCAO). Acute toxicity was determined and data showed that LD50 of AO > 5000 mg/kg BW. To determine the cerebroprotective effect of AO, male Wistar rats were orally given AO at doses of 2, 10, and 50 mg/kg for 14 days and subjected to Rt.MCAO. Brain infarction volume, neurological score, spatial memory, serum lipid profiles, and C-reactive protein together with the brain oxidative stress status were assessed. All doses of AO significantly decreased brain infarction in cortex, hippocampus, and striatum together with the decreased oxidative stress status. The improvement of spatial memory and serum C-reactive protein were also observed in MCAO rats which received AO at all doses. In addition, the decreased serum cholesterol, TG, and LDL but increased HDL were observed in MCAO rats which received high dose of AO. Taken all together, AO is the potential protectant against cerebral ischemia. The improvement of oxidative stress, inflammation, and dyslipidemia might play roles in the actions. However, further researches are required to understand the precise underlying mechanism.

Abstract
Aluminium (Al), one of the metals implicated in neurodegeneration easily gain access to the nervous system through its presence in many manufactured foods, medicines and drinking water, and causes neurotoxicity utilizing the reactive oxygen specie pathway. The need to curtail these effects on the nervous system motivated the use of the plant Moringa oleifera (MO). This study thus, investigated the neuroprotective effects of MO leaf extract on aluminium-induced temporal cortical degeneration in rats. 24 male albino Wistar rats were grouped (n = 6) into control (1 ml/kg distilled water), l00 mg/kg aluminium chloride (AlCl3), 300 mg/kg MO, and 100 mg/kg AlCl3 and 300 mg/kg MO groups. The administration lasted for 28 days and the rats were sacrificed on day 29 by perfusion-fixation after blood was obtained for serum Al estimation. The brain tissues were then routinely processed for some histological and immunnolabelling studies. There was no significant difference in serum Al in the test groups. Histological results showed atrophied and karyorrhetic cells with loss of Nissl substance in the temporal cortex of the AlCl3 group, while no adverse effect was observed in the cytoarchitecture of the temporal cortex and Nissl substance of the MO group. However, groups which were administered AlCl3 simultaneously with MO extract showed less degenerative features in the cyto-architecture of the temporal cortex with normal Nissl substance staining. There was increased neuron specific enolase (NSE) and glial fibrillary acidic protein (GFAP) expressions in the AlCl3 group, while the MO group also showed increased NSE but decreased GFAP expression. However, the group which were administered AlCl3 simultaneously with MO extract showed less expression of NSE and GFAP. In conclusion, MO protects against Al-induced neurotoxicity of the temporal cortex of rats.

Abstract
The neuroprotectant and memory enhancer supplement for menopause is required due to the side effects of hormone replacement therapy. Since purple waxy corn cob and pandan leaves exert antioxidant and acetylcholinesterase inhibition (AChEI) effects, we hypothesized that the combined extract of both plants (PCP) might provide synergistic effect leading to the improved brain damage and memory impairment in experimental menopause. To test this hypothesis, female Wistar rats were ovariectomized bilaterally and orally given various doses of the functional drink at doses of 20, 40, and 80 mg/kg for 28 days. The animals were assessed nonspatial memory using object recognition test every 7 days throughout the study period. At the end of study, they were assessed with oxidative stress status, AChEI, neuron density, and ERK1/2 signal in the prefrontal cortex (PFC). Interestingly, all doses of PCP increased object recognition memory and neuron density but decreased oxidative stress status in PFC. Low dose of PCP also decreased AChE activity while medium dose of PCP increased phosphorylation of ERK1/2 in PFC. Therefore, the improved oxidative stress status and cholinergic function together with signal transduction via ERK in PFC might be responsible for the neuroprotective and memory-enhancing effects of PCP.

Abstract
Either exercise or Ginkgo biloba is reported to improve cognitive functioning. The aim of this study is to compare the protective effects of forced exercise and Ginkgo biloba on oxidative stress as well as memory impairments induced by transient cerebral ischemia. Adult male Wistar rats were treated with treadmill running or Ginkgo biloba extract for 2 weeks before cerebral ischemia. Memory was assessed using a Morris water maze (MWM) task. At the end of the behavioral testing, oxidative stress biomarkers were evaluated in the hippocampus tissue. As expected, the cerebral ischemia induced memory impairment in the MWM task, and oxidative stress in the hippocampus. These effects were significantly prevented by treadmill running. Indeed, it ameliorated oxidative stress and memory deficits induced by ischemia. In contrast, Ginkgo biloba was not as effective as exercise in preventing ischemia-induced memory impairments. The results confirmed the neuroprotective effects of treadmill running on hippocampus-dependent memory.

Abstract
Many studies of brain ischemia have shown the role played by massive ischemia-induced production of reactive oxygen species, the main mechanism of neuronal death. However, currently, there is no treatment choice to prevent cell death triggered by reactive oxygen species. In our study, we researched the effects of tannic acid, an antioxidant, on the ischemic tissue of rats with induced middle cerebral artery occlusion. The animals were divided into three groups of eight animals. The sham group were only administered 10 % ethanol intraperitoneally, the second group had middle cerebral artery occlusion induced and were given 10 % ethanol intraperitoneally, while the third group had middle cerebral artery occlusion with 10 mg/kg dose tannic acid dissolved in 10 % ethanol administered within half an hour intraperitoneally. The rats were sacrificed 24 h later, and brain tissue was examined biochemically and histopathologically. Biochemical evaluation of brain tissue found that comparing the ischemic group with no treatment with the tannic acid-treated ischemia group; the superoxide dismutase (SOD) levels were higher, malondialdehyde (MDA) levels were lower, and nuclear respiratory factor-1 (NRF-1) was higher in the tannic acid-treated group. Histopathological examination showed that the histopathological results of the tannic acid group were better than the group not given tannic acid. Biochemical and histopathological results showed that tannic acid administration had an antioxidant effect on the negative effects of ischemia in brain tissue.

Autistic-Like Behaviors, Oxidative Stress Status, and Histopathological Changes in Cerebellum of Valproic Acid Rat Model of Autism Are Improved by the Combined Extract of Purple Rice and Silkworm Pupae. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2016; 2016:3206561.

Abstract
Due to the crucial role of oxidative stress on the pathophysiology of autism and the concept of synergistic effect, the benefit of the combined extract of purple rice and silkworm pupae (AP1) for autism disorder was the focus. Therefore, we aimed to determine the effect of AP1 on autistic-like behaviors, oxidative stress status, and histopathological change of cerebellum in valproic acid (VPA) rat model of autism. VPA was injected on postnatal day (PND) 14 and the animals were orally given AP1 at doses of 50, 100, and 200 mg·kg−1 BW between PND 14 and PND 40. The autism-like behaviors were analyzed via hot-plate, rotarod, elevated plus-maze, learning, memory, and social behavior tests. Oxidative stress and the histological change in the cerebellum were assessed at the end of study. AP1 treated rats improved behaviors in all tests except that in hot-plate test. The improvement of oxidative stress and Purkinje cell loss was also observed in the cerebellum of VPA-treated rats. Our data suggest that AP1 partially reduced autism-like behaviors by improving oxidative stress and Purkinje cell loss. Further research is required to identify the active ingredients in AP1 and gender difference effect.

Abstract
The discovery of new natural compounds with pharmacological properties is a field of interest widely growing, especially for the management of neurodegenerative diseases. As no pharmacological treatment is available to prevent the development of these disorders, dietary intake of foods or plant-based extracts with antioxidant properties might have beneficial effects on human health and improve brain functions. Isothiocyanates (ITCs), derived from the hydrolysis of the corresponding glucosinolates (GLs), mainly found in Brassica vegetables (Brassicaceae) and, to a lesser extent, in Moringaceae plants, have demonstrated to exert neuroprotective properties. Specifically, strong evidences suggest that antioxidant effects may be ascribed mainly to their peculiar ability to activate the Nrf2/ARE pathway, but alternative mechanisms of action have also been suggested. This review summarizes the current knowledge about the neuroprotective effects of ITCs in counteracting oxidative stress as well as inflammatory and apoptotic mechanisms, using in vitro and in vivo models of acute and chronic neurodegenerative disease. Therefore, ITCs could be regarded as a promising source of alternative medicine for the prevention and/or treatment of neurodegenerative diseases.

Abstract
Moringa oleifera leaves, seeds, bark, roots, sap, and flowers are widely used in traditional medicine, and the leaves and immature seed pods are used as food products in human nutrition. Leaf extracts exhibit the greatest antioxidant activity, and various safety studies in animals involving aqueous leaf extracts indicate a high degree of safety. No adverse effects were reported in association with human studies. Five human studies using powdered whole leaf preparations of M. oleifera have been published, which have demonstrated anti‐hyperglycemic (antidiabetic) and anti‐dyslipidemic activities. These activities have been confirmed using extracts as well as leaf powders in animal studies. A rapidly growing number of published studies have shown that aqueous, hydroalcohol, or alcohol extracts of M. oleifera leaves possess a wide range of additional biological activities including antioxidant, tissue protective (liver, kidneys, heart, testes, and lungs), analgesic, antiulcer, antihypertensive, radioprotective, and immunomodulatory actions. A wide variety of polyphenols and phenolic acids as well as flavonoids, glucosinolates, and possibly alkaloids is believed to be responsible for the observed effects. Standardization of products is an issue. However, the results of published studies to date involving M. oleifera are very promising. Additional human studies using standardized extracts are highly desirable. © 2015 The Authors Phytotherapy Research Published by John Wiley & Sons Ltd.

Osthole, a natural coumarin improves cognitive impairments and BBB dysfunction after transient global brain ischemia in C57 BL/6J mice: involvement of Nrf2 pathway. Neurochem Res 2014; 40:186-94. [PMID: 25424966 DOI: 10.1007/s11064-014-1483-z] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2014] [Revised: 11/16/2014] [Accepted: 11/19/2014] [Indexed: 01/01/2023]
Abstract
Oxidative stress and blood-brain barrier (BBB) disruption play important roles in cerebral ischemic pathogenesis and may represent targets for treatment. Earlier studies have shown that osthole, a main active constituent isolated from Cnidium monnieri (L.) Cusson, could be considered as an attractive therapeutic agent in the treatment of ischemic stroke. However, the mechanism underlying the protective effect remains vague. In this study we aimed to investigate the effect of osthole on transient cerebral ischemia as well as its mechanism(s) in C57 BL/6 J mice. Mice were subjected to transient global cerebral ischemia induced by bilateral common carotid artery occlusion for 25 min. Behavioral test was performed at 4 days after ischemia, followed by assessment of neuronal loss in hippocampal CA1 region. Osthole significantly improved the cognitive ability and enhanced the survival of pyramidal neurons in the CA1 region of mice after lesion. Further studies showed that osthole attenuated the permeation of BBB, which may contribute to antioxidative effect by increasing the superoxide dismutase activity and decreasing the malondialdehyde level in model mice. Further studies revealed that osthole obviously up-regulated the protein levels of nuclear factor erythroid 2-related factor 2/heme oxygenase 1 in HT22 cells. In conclusion, our findings indicated that osthole exerts neuroprotective effects against global cerebral ischemia injury by reducing oxidative stress injury and reserving the disruption of BBB, which may be attributed to elevating the protein levels of Nrf2 and HO-1.
