Abstract
OBJECTIVE The Manihot esculenta Crantz (Cassava) is a typical South American plant rich in nutrients and energetic compounds. Lately, our group has shown that non-pharmacological interventions with natural antioxidants present different neuroprotective effects on oxidative balance and memory deficits in AD-like animal models. Here, our objective was to evaluate the neuroprotective effects of Cassava leaves' extract (CAS) in an AD-like model induced by amyloid-beta (Aβ) 25-35 peptide. METHODS Male Wistar rats (n = 40; 60 days old) were subjected to 10 days of CAS supplementation; then, we injected 2 μL Aβ 25-35 in the hippocampus by stereotaxic surgery. Ten days later, we evaluated object recognition (OR) memory. Cassavas' total polyphenols, flavonoids, and condensed tannins content were measured, as well as hippocampal lipid peroxidation and total antioxidant capacity. RESULTS CAS protected against Aβ-induced OR memory deficits. In addition, Aβ promoted antioxidant capacity decrease, while CAS was able to prevent it, in addition to diminishing lipoperoxidation compared to Aβ. DISCUSSION We show that treatment with Cassava leaves' extract before AD induction prevents recognition memory deficits related to Aβ hippocampal injection. At least part of these effects can be related to the Cassava leaves' extract supplementation effects on diminishing lipid peroxidation and preventing a decrease in the hippocampal total antioxidant capacity in the hippocampus of AD-like animals without adverse effects. Once cassavais a plant of warm and dry ground that can adapt to growon various soil types and seems to resist several insects, our results enable Cassava to be considered asa potential preventive intervention to avoid or minimizeAD-induced memory deficits worldwide.

Abstract
The Pequi fruit (Caryocar Brasiliense cambess), typical of the Brazilian cerrado or savannah, is a source of essential fatty acids, carotenoids, and phenolic compounds. The aim of this study was to analyze the effects of consuming this fruit on anxiety behavior and lipid peroxidation in the brains of rats whose mothers were treated (by gavage) during pregnancy and lactation with Pequi fruit (pulp or nuts) at 2000 mg/kg of body weight. Anxiety parameters were assessed using the open field (OF), elevated plus maze (EPM), and light/dark box (LDB) tests. The brain was removed to measure malondialdehyde (MDA) levels. Data were analyzed using One-way Anova (p < 0.05). In the OF, the animals in the pulp group presented more time spent in the central area (20.37 ± 0.73 vs Control: 12.51 ± 0.39; Nuts: 8.28 ± 0.40) and increased locomotion (159.7 ± 6.10) compared to the other groups (Control: 127.3 ± 5.54; Nuts: 139.08 ± 6.57). In the EPM, the pulp group entered into the open arms (8.57 ± 0.36) and stayed more time in the central area (19.44 ± 1.17) compared to the Nuts group (7.14 ± 0.34; 13.00 ± 1.57). In the LDB the pulp group entered more (8.00 ± 0.42 vs Control: 7.16 ± 0.16 and Nuts: 7.42 ± 0.75) and stayed longer in the clear light side (92.18 ± 6.42) than all the other groups (Control: 71.44 ± 3.53; Nuts: 80.57 ± 6.50), respectively. Pulp group presented lower MDA in the brain (55.34 ± 3.04) compared to Control (72.06 ± 4.66) and Nuts (66.57 ± 2.45). We conclude that Pequi pulp consumption during pregnancy and lactation reduces lipid peroxidation in brain tissue and induces anxiolytic-like behavior in rat offspring. These effects were not observed in the Pequi nuts group.

Abstract
Donkey milk (DM) is a source of bioactive compounds that can benefit neural functioning. In the present study, we investigated the effects of DM consumption on anxiolytic-related, despair-like, locomotion and coordination behaviors, as well as the provision of protection from oxidative damage to lipids and proteins in brain tissues and melatonin plasma levels. To achieve this, male mice orally received DM (4g.kg-1) or vehicle for 18 days. Their behavior was assessed in the following tests: elevated plus maze (EPM), open field and rotarod tests (OF, RR) and forced swimming test (FST). Acute treatments with diazepam (DZP, 1.5mg.kg-1, v.o.), fluoxetine (FLX, 20mg.kg-1, i.p.) and nortriptyline (NTP, 20mg.kg-1, i.p.) were used as positive controls. On the eighteenth day, the animals were euthanized and brain tissue and blood were collected to measure oxidative damage, and melatonin plasma levels. Similar to DZP, repeated DM consumption reduced exploration to open areas in the EPM test. Under our experimental conditions, conventional antidepressants reduced immobility time in the FST, and the benzodiazepine treatment impaired motor coordination in mice. No significant differences in locomotion, motor coordination and despair-related behaviors were observed in the mice treated with DM when assessed in the EPM, OF, RR and FST, respectively. Biochemical assays showed that repeated DM exposition protected against oxidative damage to lipids and increased plasma levels of melatonin. These findings suggest consumption of DM may be a promising food for the treatment of anxiety-related disorders, without depressant effects on the central nervous system.

Abstract
Phytopharmaceuticals have attracted a lot of attention due to their multicomponent and multiple targets. The natural phenolic chemicals known as flavonoids are found in a wide variety of plants, fruits, vegetables, and herbs. Recently, they have been found to have modulatory effects on anxiety disorders, with current research focusing on the modulation of neurotransmitters. There has not yet been a review of the various natural flavonoid monomer compounds and total plant flavonoids that have been found to have anxiolytic effects. The study on the anti-anxiety effects of plant-derived flavonoids on neurotransmitters was reviewed in this paper. We, therefore, anticipate that further study on the conformational interaction underlying flavonoids' anti-anxiety effects will offer a theoretical framework for the creation of pertinent treatments.

Abstract
Mental health is a global public concern that contributes raising disability and premature death. Anxiety undertakes around 3.6% of the global population, while psychological stress is a condition associated to anxiety with a prevalence of 36.5%. Treatment for both mental conditions consist mainly of psychological therapy and pharmacotherapy, but the long-term drugs use can trigger adverse effects. Growing evidence shows the effect of specific food compounds on stress and anxiety treatment. The aim of this systematic review is to describe the molecular mechanisms related to dietary polyphenols administration from food matrix (considering food, juices or herbal/food extracts) and their effects on stress and/or anxiety, as well as review the available clinical evidence. Search was based on PRISMA Guidelines using peer-reviewed journal articles sourced from PubMed and Web of Science. A total of 38 articles were considered as eligible. The major effects for anxiety management were: reduction of oxidative stress and inflammation; HPA axis modulation; and regulation of some serotonergic/adrenergic pathways. There is a very limited evidence to conclude about the real effect of dietary polyphenols on stress. Although pharmacological treatment for mood disorders is essential, alternative therapies are necessary using non-pharmacological compounds to improve the long-term treatment effectiveness.

Abstract
There is scientific evidence of the positive effect of polyphenols from plant foods on inflammation and oxidative status. The aim of the present study was to investigate whether treatment with a high-polyphenolic nutraceutical reduces the plasmatic concentration of certain oxidative and inflammatory biomarkers in a healthy population. One hundred and eight subjects were selected and stratified by sex in the intervention group (n = 53) and the placebo group (n = 55). Ninety-two subjects completed the study after two 16-week treatment periods separated by a four-week washout period. The results revealed statistically significant differences in subjects treated with the polyphenolic extract compared to the placebo: A decrease in homocysteine, oxidized low-density lipoprotein (OxLDL), TNF-α, sTNFR1, and C-reactive protein (CRP). The most significant decrease was observed for OxLDL (from 78.98 ± 24.48 to 69.52 ± 15.64; p < 0.05) and CRP (from 1.50 ± 0.33 to 1.39 ± 0.37; p < 0.05), both showing significant differences compared to the placebo (p < 0.001). Moreover, catecholamines increased after the administration of the product under investigation, especially in the case of dopamine (from 15.43 ± 2.66 to 19.61 ± 5.73; p < 0.05). Therefore, the consumption of a nutraceutical based on fruit and vegetables with a high polyphenol content seems to improve the parameters related to health benefits (oxidative and inflammatory biomarkers), including remarkable changes in the expression of catecholamines.

Abstract
This study evaluated the effect of Mucuna pruriens (MP) administration on neuroinflammation and behavioral and murinometric parameters in obese rats. Proximate composition, oligosaccharide and phenolic compound profile of MP were determined. Wistar adult male rats were randomized into healthy (HG) and obese group (OG). The HG consumed a control chow diet while OG consumed a cafeteria diet for eight weeks. Then, they were subdivided into: Healthy (HG); Healthy with MP administration (HGMP); Obese (OG); Obese with MP administration (OGMP), with the consumption of the respective diets remaining for another eight weeks, in addition to gavage with MP extract to supplemented groups (750 mg/kg weight). MP presented a composition rich in proteins and phenolic compounds, especially catechin, in addition to 1-kestose and levodopa. Supplementation reduced food intake, body weight, and thoracic and abdominal circumferences in obese rats. MP showed anxiolytic and antidepressant effects and reduced morphological damage and expression of interleukin 6 in the hippocampus of obese rats. MP treatment showed satietogenic, slimming, anxiolytic and antidepressant effects, besides to minimizing hippocampal neuroinflammation in obese rats. Our results demonstrated the potential anti-obesity of MP which are probably related to the high content of bioactive compounds present in this plant extract.

Abstract
Polyphenols, a category of plant compounds that contain multiple phenol structural units, are widely distributed throughout the plant kingdom and have multiple benefits for human health including anti-obesity, anti-hyperglycemic, and anti-hyperlipidemic effects. Additionally, polyphenols have recently gained attention for their anti-stress effects. In this review article, we summarize physiological responses against exposure to stressors and discuss biomarkers for exposure to stressors that are widely used in animal studies and human trials. We also review commonly used animal models for evaluating anti-stress effects. Finally, we discuss recent findings related to the anti-stress effects of polyphenols evaluated in animal models and human trials, and their putative mechanisms. These emerging data require further investigation in scientific studies and human trials to evaluate the anti-stress effects of polyphenols and their potential use for the prevention of stress-related health problems.

Abstract
Many studies suggest a protective role of phenolic compounds in mood disorders. We aimed to assess the effect of Euterpe oleracea (açaí) seed extract (ASE) on anxiety induced by periodic maternal separation (PMS) in adult male rats. Animals were divided into 6 groups: control, ASE, fluoxetine (FLU), PMS, PMS+ASE, and PMS+FLU. For PMS, pups were separated daily from the dam for 3 h between postnatal day (PN) 2 and PN21. ASE (200 mg·kg-1·day-1) and FLU (10 mg·kg-1·day-1) were administered by gavage for 34 days after stress induction, starting at PN76. At PN106 and PN108, the rats were submitted to open field (OF) and forced swim tests, respectively. At PN110, the rats were sacrificed by decapitation. ASE increased time spent in the center area in the OF test, glucocorticoid receptors in the hypothalamus, tropomyosin receptor kinase B (TRKB) levels in the hippocampus, and nitrite levels and antioxidant activity in the brain stem (PMS+ASE group compared with PMS group). ASE also reduced plasma corticotropin-releasing hormone levels, adrenal norepinephrine levels, and oxidative damage in the brain stem in adult male offspring submitted to PMS. In conclusion, ASE treatment has an anti-anxiety effect in rats submitted to PMS by reducing hypothalamic-pituitary-adrenal axis reactivity and increasing the nitric oxide (NO)-brain-derived neurotrophic factor (BDNF)-TRKB pathway and antioxidant defense in the central nervous system. Novelty ASE has anti-anxiety and antioxidant effects in early-life stress. ASE reduces hypothalamic-pituitary-adrenal axis reactivity. The anxiolytic effect of ASE may involve activation of the NO-BDNF-TRKB pathway in the central nervous system.

Abstract
This article is a comprehensive review of the literature pertaining to the antidepressant effects and mechanisms of regular tea consumption. Meta-data supplemented with recent observational studies were first analyzed to assess the association between tea consumption and depression risk. The literature reported risk ratios (RR) were 0.69 with 95% confidence intervals of 0.62–0.77. Next, we thoroughly reviewed human trials, mouse models, and in vitro experiments to determine the predominant mechanisms underlying the observed linear relationship between tea consumption and reduced risk of depression. Current theories on the neurobiology of depression were utilized to map tea-mediated mechanisms of antidepressant activity onto an integrated framework of depression pathology. The major nodes within the network framework of depression included hypothalamic-pituitary-adrenal (HPA) axis hyperactivity, inflammation, weakened monoaminergic systems, reduced neurogenesis/neuroplasticity, and poor microbiome diversity affecting the gut–brain axis. We detailed how each node has subsystems within them, including signaling pathways, specific target proteins, or transporters that interface with compounds in tea, mediating their antidepressant effects. A major pathway was found to be the ERK/CREB/BDNF signaling pathway, up-regulated by a number of compounds in tea including teasaponin, L-theanine, EGCG and combinations of tea catechins and their metabolites. Black tea theaflavins and EGCG are potent anti-inflammatory agents via down-regulation of NF-κB signaling. Multiple compounds in tea are effective modulators of dopaminergic activity and the gut–brain axis. Taken together, our findings show that constituents found in all major tea types, predominantly L-theanine, polyphenols and polyphenol metabolites, are capable of functioning through multiple pathways simultaneously to collectively reduce the risk of depression.
