Abstract
Selective Androgen Receptor Modulators (SARMs), particularly (17α,20E)-17,20-[(1-methoxyethylidene)bis(oxy)]-3-oxo-19-norpregna-4,20-diene-21-carboxylic-acid-methyl-ester (YK11), are increasingly popular among athletes seeking enhanced performance. Serving as an Androgen Receptor (AR) agonist, YK11 stimulates muscle growth while inhibiting myostatin. Our study delved into the impact of YK11 on the rat hippocampus, analyzing potential alterations in neurochemical mechanisms and investigating its synergistic effects with exercise (EXE), based on the strong relationship between SARM users and regular exercise. Utilizing Physiologically Based Pharmacokinetic (PBPK) modeling, we demonstrated YK11 remarkable brain permeability, with molecular docking analysis revealing YK11 inhibitory effects on 5-alpha-reductase type II (5αR2), suggesting high cell bioavailability. Throughout a 5-week experiment, we divided the animals into the following groups: Control, YK11 (0.35 g/kg), EXE (swimming exercise), and EXE + YK11. Our findings showed that YK11 displayed a high binding affinity with AR in the hippocampus, influencing neurochemical function and modulating aversive memory consolidation, including the downregulation of the BDNF/TrkB/CREB signaling, irrespective of EXE combination. In the hippocampus, YK11 increased pro-inflammatory IL-1β and IL-6 cytokines, while reducing anti-inflammatory IL-10 levels. However, the EXE + YK11 group counteracted IL-6 effects and elevated IL-10. Analysis of apoptotic proteins revealed heightened p38 MAPK activity in response to YK11-induced inflammation, initiating the apoptotic cascade involving Bax/Bcl-2/cleaved caspase-3. Notably, the EXE + YK11 group mitigated alterations in Bcl-2 and cleaved caspase-3 proteins. In conclusion, our findings suggest that YK11, at anabolic doses, significantly alters hippocampal neurochemistry, leading to impairments in memory consolidation. This underscore concerns about the misuse risks of SARMs among athletes and challenges common perceptions of their minimal side effects.

Abstract
Evidence has shown that consuming trans fatty acids (TFA) during development leads to their incorporation into the nervous tissue, resulting in neurological changes in flies. In this study, Drosophila melanogaster was exposed to different concentrations of hydrogenated vegetable fat (HVF) during development: substitute hydrogenated vegetable fat (SHVF), HVF 10 %, and HVF 20 %. The objective was to evaluate the effects of early trans fat exposure on cognition and associated pathways in flies. The results showed that early TFA exposure provoked a cerebral redox imbalance, as confirmed by increased reactive species (HVF 10 and 20 %) and lipid peroxidation (SHVF, HVF 10, and 20 %), reduced nuclear factor erythroid 2-related factor 2 immunoreactivity (HVF 10 and 20 %), and increased heat shock protein 70 (HVF 20 %), which was possibly responsible for decreasing superoxide dismutase (SHVF, HVF 10, and 20 %) and catalase (HVF 20 %) activities. Furthermore, the presence of TFA in nervous tissue impaired learning (HVF 10 and 20 %) and memory at 6 and 24 h (SHVF, HVF 10, and 20 %). These cognitive impairments may be linked to reduced Shank levels (HVF 20 %) and increased acetylcholinesterase activity (SHVF, HVF 10 and 20 %) observed. Our findings demonstrate that early exposure to trans fat leads to cerebral redox imbalance, altering proteins associated with stress, synaptic plasticity, and the cholinergic system, consequently leading to cognitive impairment in flies.

Abstract
Memory consolidation is associated with the regulation of protein kinases, which impact synaptic functions and promote synaptogenesis. The administration of spermidine (SPD) has been shown to modulate major protein kinases associated with memory improvement, including the Ca2+-dependent protein kinase (PKC) and cAMP-dependent protein kinase (PKA), key players in the cAMP response element-binding protein (CREB) activation. Nevertheless, the initial mechanism underlying SPD-mediated memory consolidation remains unknown, as we hypothesize a potential involvement of the memory consolidation precursor, Ca2+/calmodulin-dependent protein kinase II-α (CaMKIIα), in this process. Based on this, our study aimed to investigate potential interactions among PKC, PKA, and CREB activation, mediated by CaMKIIα activation, in order to elucidate the SPD memory consolidation pathway. Our findings suggest that the post-training administration of the CaMKII inhibitor, KN-62 (0.25 nmol, intrahippocampal), prevented the memory enhancement induced by SPD (0.2 nmol, intrahippocampal) in the inhibitory avoidance task. Through western immunoblotting, we observed that phosphorylation of CaMKIIα in the hippocampus was facilitated 15 min after intrahippocampal SPD administration, resulting in the activation of PKA and CREB, 180 min after infusion, suggesting a possible sequential mechanism, since SPD with KN-62 infusion leads to a downregulation in CaMKIIα/PKA/CREB pathway. However, KN-62 does not alter the memory-facilitating effect of SPD on PKC, possibly demonstrating a parallel cascade in memory acquisition via PKA, without modulating CAMKIIα. These results suggest that memory enhancement induced by SPD administration involves crosstalk between CaMKIIα and PKA/CREB, with no PKC interaction.

Abstract
Bisphenol F (BPF) and Bisphenol S (BPS) are being widely used by the industry with the claim of "safer substances", even with the scarcity of toxicological studies. Given the etiological gap of autism spectrum disorder (ASD), the environment may be a causal factor, so we investigated whether exposure to BPF and BPS during the developmental period can induce ASD-like modeling in adult flies. Drosophila melanogaster flies were exposed during development (embryonic and larval period) to concentrations of 0.25, 0.5, and 1 mM of BPF and BPS, separately inserted into the food. When they transformed into pupae were transferred to a standard diet, ensuring that the flies (adult stage) did not have contact with bisphenols. Thus, after hatching, consolidated behavioral tests were carried out for studies with ASD-type models in flies. It was observed that 1 mM BPF and BPS caused hyperactivity (evidenced by open-field test, negative geotaxis, increased aggressiveness and reproduction of repetitive behaviors). The flies belonging to the 1 mM groups of BPF and BPS also showed reduced cognitive capacity, elucidated by the learning behavior through aversive stimulus. Within the population dynamics that flies exposed to 1 mM BPF and 0.5 and 1 mM BPS showed a change in social interaction, remaining more distant from each other. Exposure to 1 mM BPF, 0.5 and 1 mM BPS increased brain size and reduced Shank immunoreactivity of adult flies. These findings complement each other and show that exposure to BPF and BPS during the development period can elucidate a model with endophenotypes similar to ASD in adult flies. Furthermore, when analyzing comparatively, BPS demonstrated a greater potential for damage when compared to BPF. Therefore, in general these data sets contradict the idea that these substances can be used freely.

Abstract
The behavior and neuronal ganglia integrity of Drosophila melanogaster larvae exposed to Bisphenol F (BPF) and Bisphenol S (BPS) (0.25, 0.5 and 1 mM) was evaluated. Larvae exposed to BPF and BPS (0.5 and 1 mM) showed hyperactivity, reduced decision-making capacity and were not responsive to touch (no sensitivity to physical stimuli). There was also a reduction in the tunneling capacity induced by 1 mM of BPF and BPS (innate behaviors for survival). Behaviors resulting from changes in neuronal functioning, thermotaxis and phototaxis showed that BPS was more harmful compared to BPF. Furthermore, the concentration of 1 mM BPS generated greater damage to neuronal ganglia when compared to BPF. This difference may be related to the LC50 of the 10.04 mM BPS and 15.07 mM BPF. However, these behavioral changes presented by the larvae here are characteristic of those presented in neurodevelopmental disorders. Our findings are novel and refute the possibility that BPF and BPS are safer alternatives.

Abstract
We investigated a possible toxic effect induced by chronic exposure to free curcumin and curcumin-loaded nanocapsules in Drosophila melanogaster, enabling safe applications. Flies of both sexes were divided into groups: control group; free curcumin at concentrations of 10, 30, 100, 300, 900, and 3000 μM; curcumin-loaded nanocapsules at concentrations of 10, 30, 100, and 300 μM. Initially, the diet consumption test was evaluated in flies exposed to different concentrations. During the 10-day treatment, the flies were evaluated for percentage survival. After the treatment, behaviors (geotaxis negative and open field), acetylcholinesterase activity (AChE), and oxidative stress parameters (reactive species (RS) and thiobarbituric acid reactive substances (TBARS) levels, Glutathione-S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT) enzymes activity, erythroid-derived nuclear factor 2 (Nrf2) immunoreactivity, and cellular metabolic capacity, were assessed. No significant difference in diet consumption, indicating that the flies equally consumed the different concentrations of free curcumin and the curcumin-loaded nanocapsules. Was observed that free curcumin and curcumin-loaded nanocapsules increased survival, locomotor and exploratory performance, decreased AChE activity, RS and TBARS levels, increased GST, SOD and CAT activity, Nrf2 and viable cells compared to the control. The chronic treatment did not cause toxicity, suggesting that nanoencapsulation of curcumin could be explored.

Abstract
Our study investigates potential neurochemical effects of (17α,20E)- 17,20-[(1-methoxyethylidene)bis(oxy)]- 3-oxo-19-norpregna-4,20-diene-21-carboxylic acid methyl ester (YK11), a selective androgen receptor modulator (SARM), in the rat hippocampus, with a particular focus on oxidative stress and mitochondrial function, as well as its potential effect when combined with exercise (EXE). To validate YK11's anabolic potential, we performed a molecular docking analysis with the androgen receptor (AR), which showed high affinity with YK11, highlighting hydrogen interactions in Arg752. During the five-week protocol, we divided male Wistar rats into the following groups: Control, YK11 (0.35 g/kg), EXE (swimming protocol), and EXE+YK11. The administration of YK11 resulted in alterations in the endogenous antioxidant system, promoting increased oxidative stress and proteotoxic effects, impairing all mitochondrial function markers in the hippocampus. In contrast, EXE alone had a neuroprotective effect, increasing antioxidant defenses and improving mitochondrial metabolism. When combined, EXE+YK11 prevented alterations in some mitochondrial toxicity markers, including MnSOD/SOD2 and MTT reduction capacity, but did not reverse YK11's neurochemical impairments regarding increased oxidative stress and dysfunction of the mitochondrial respiratory chain and mitochondrial dynamics regulatory proteins in the hippocampus. In summary, our study identifies important pathways of YK11's hippocampal effects, revealing its potential to promote oxidative stress and mitochondrial dysfunction, suggesting that the administration of YK11 may pose potential neurological risks for athletes and bodybuilders seeking to enhance performance. These findings highlight the need for further research to assess the safety and efficacy of YK11 and SARM use in humans.

Abstract
This study investigated the potential effects of exercise on the responses of energy metabolism, redox balance maintenance, and apoptosis regulation in Drosophila melanogaster to shed more light on the mechanisms underlying the increased performance that this emerging exercise model provides. Three groups were evaluated for seven days: the control (no exercise or locomotor limitations), movement-limited flies (MLF) (no exercise, with locomotor limitations), and EXE (with exercise, no locomotor limitations). The EXE flies demonstrated greater endurance-like tolerance in the swimming test, associated with increased citrate synthase activity, lactate dehydrogenase activity and lactate levels, and metabolic markers in exercise. Notably, the EXE protocol regulated the Akt/p38 MAPK/Nrf2 pathway, which was associated with decreased Hsp70 activation, culminating in glutathione turnover regulation. Moreover, reducing the locomotion environment in the MLF group decreased endurance-like tolerance and did not alter citrate synthase activity, lactate dehydrogenase activity, or lactate levels. The MLF treatment promoted a pro-oxidant effect, altering the Akt/p38 MAPK/Nrf2 pathway and increasing Hsp70 levels, leading to a poorly-regulated glutathione system. Lastly, we demonstrated that exercise could modulate major metabolic responses in Drosophila melanogaster aerobic and anaerobic metabolism, associated with apoptosis and cellular redox balance maintenance in an emergent exercise model.

Abstract
β-carotene-loaded nanoparticles improves absorption by increasing bioavailability. The Drosophila melanogaster model of Parkinson's disease must be helpful in investigating potential neuroprotective effects. Four groups of four-day-old flies were exposed to: (1) control; (2) diet containing rotenone (500 μM); (3) β-carotene-loaded nanoparticles (20 μM); (4) β-carotene-loaded nanoparticles and rotenone for 7 days. Then, the percentage of survival, geotaxis tests, open field, aversive phototaxis and food consumption were evaluated. At the end of the behaviors, the analyses of the levels of reactive species (ROS), thiobarbituric acid reactive substances (TBARS), catalase (CAT) and superoxide dismutase (SOD) activity was carried out, as well as an evaluation of the levels of dopamine and acetylcholinesterase (AChE) activity, in the head of flies. Nanoparticles loaded with β-carotene were able to improve motor function, memory, survival and also restored the oxidative stress indicators (CAT, SOD, ROS and TBARS), dopamine levels, AChE activity after exposure to rotenone. Overall, nanoparticles loaded with β-carotene showed significant neuroprotective effect against damage induced by the Parkinson-like disease model, emerging as a possible treatment. Overall, β-carotene-loaded nanoparticles presented significant neuroprotective effect against damage induced by model of Parkinson-like disease, emerging as a possible treatment.

Abstract
Given the importance of understanding the disorders caused by trans fatty acids (TFAs), this study sought to add different concentrations hydrogenated vegetable fat (HVF) to the diet of Drosophila melanogaster during the developmental period and evaluate the effects on neurobehavioral parameters. Longevity, hatching rate, and behavioral functions were assessed, such as negative geotaxis, forced swimming, light/dark, mating, and aggressiveness. The fatty acids (FAs) present in the heads of the flies were quantified as well as serotonin (5HT) and dopamine (DA) levels. Our findings showed that flies that received HVF at all concentrations during development showed reduced longevity and hatching rates, in addition to increased depression-like, anxious-like, anhedonia-like, and aggressive behaviors. As for the biochemical parameters, there was a more significant presence of TFA in flies exposed to HVF at all concentrations evaluated and lower 5HT and DA levels. This study shows that HVF during the developmental phase can cause neurological changes and consequently induce behavioral disorders, thereby highlighting the importance of the type of FA offered in the early stages of life.

Abstract
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social interaction and repetitive behaviors. In this study, we assessed the effect of lutein-loaded nanoparticles on ASD-like behaviors induced by prenatal valproic acid (VPA) exposure in female offspring rats and the possible involvement of oxidative stress and apoptosis. Pregnant female Wistar rats received a single intraperitoneal injection of VPA (600 mg/kg), on the gestational day 12.5. The VPA-exposed female offspring rats were divided into two subgroups and received either lutein-loaded nanoparticles (5 mg/kg) or saline by oral gavage, for 14 days. The animals were submitted to the three-chamber test and open field to evaluate ASD-like behaviors. The hippocampus was removed for the determination of oxidative stress indicators (ROS; TBARS; SOD and Nrf2) and apoptosis biomarkers (Hsp-70; p38-MAPK; Bax and Bcl-2). The exposure to lutein-loaded nanoparticles reversed sociability deficit, social memory deficit, and anxiety-like and repetitive behaviors induced by VPA, and restored the oxidative stress indicators and apoptosis biomarkers in the hippocampus. This neurochemical effect must be associated with the reversal of ASD-like behaviors. These results provide evidence that lutein-loaded nanoparticles are an alternative treatment for VPA-induced behavioral damage in female rats and suggest the involvement of oxidative stress.

Abstract
Drug repurposing allows searching for new biological targets, especially against emerging diseases such as Covid-19. Drug colchicine (COL) presents recognized anti-inflammatory action, while the nanotechnology purpose therapies with low doses, efficacy, and decrease the drug's side-effects. This study aims to evaluate the effects of COL and colchicine nanocapsules (NCCOL) on survival, LC50, activity locomotor, and oxidative stress parameters, elucidating the toxicity profile in acute and chronic exposure in Drosophila melanogaster. Three-day-old flies were investigated into groups: Control, 0.001, 0.0025, 0.005, and 0.010 mg/mL of COL or NCCOL. The survival rate, open field test, LC50, oxidative stress markers (reactive species (RS) production, thiobarbituric acid reactive substances), antioxidant enzyme activity (catalase (CAT), superoxide dismutase (SOD), glutathione S-transferase), protein thiols, nonprotein thiols, acetylcholinesterase activity, and cell viability were measured. As a result, acute exposure to the COL decreases the number of crosses in the open field and increases CAT activity. NCCOL reduced RS levels, increased lipoperoxidation and SOD activity. Chronic exposure to the COL and NCCOL in high concentrations implied high mortality and enzymatic inhibition of the CAT and AChE, and only the COL caused locomotor damage in the open field test. Thus, NCCOL again reduced the formation of RS while COL increased. In this comparative study, NCCOL was less toxic to the antioxidant system than COL and showed notable involvement of oxidative stress as one of their toxicity mechanisms. Future studies are needed to elucidate all aspects of nanosafety related to the NCCOL.

Abstract
Female and male Drosophila melanogaster were exposed separately for seven days to Bisphenol A (BPA), Bisphenol F (BPF), and Bisphenol S (BPS) at concentrations of 0.25, 0.5, and 1 mM. We observed that males exposed to 0.5 and 1 mM BPS showed lower catalase (CAT) activity and higher superoxide dismutase (SOD) and reactive species (RS); CAT activity decreased for BPF 0.5 and 1 mM. Nevertheless, BPA 0.5 and 1 mM decreased CAT activity, increased RS and lipid peroxidation (LPO), and reduced mitochondrial viability. None of the bisphenols altered the cell viability of male flies, although BPA 0.5 and 1 mM reduced longevity. In female flies, BPA and BPS 0.5 and 1 mM increased RS and LPO levels and decreased CAT activity and glutathione-S-transferase (GST), which may have contributed to lower mitochondrial and cell viability. Furthermore, BPS decreased SOD activity at the 1 mM concentration, and BPA reduced the SOD activity at concentrations of 0.5 and 1 mM. In the BPF 1 mM group, there was a reduction in GST activity and an increase in RS and LPO levels. The toxicological effects were different between sexes, and BPA was more harmful than BPF and BPS in male flies. Thus, our findings showed that females were more susceptible to oxidative cell damage when exposed to BPA and BPS than to BPF, and daily exposure to BPA and BPS at all concentrations reduced female longevity, as well as in BPF 1 mM.

Abstract
Environmental factors are involved in the pathogenesis of neurodevelopmental disorders in addition to genetic factors. In this sense, we demonstrated here that the embryonic exposure of Drosophila melanogaster to Bisphenol A (BPA) 1 mM resulted in changes in development, behavior, and biochemical markers punctuated below. BPA did not alter the oviposition and viability of the eggs, however, it was evidenced a decrease in the rate of pupal eclosion and life span of the hatched flies of the generation filial 1 (F1). F1 flies also developed behavioral changes such as incompatibility in the social interaction between them, and hyperactivity demonstrated by increased locomotion in open field tests, increased grooming, and aggression episodes. Furthermore, decreases in dopamine levels and tyrosine hydroxylase activity have also been observed in flies' heads, possibly related to oxidative damage. Through analyzes of oxidative stress biomarkers, carried out on samples of flies' heads, we observed an increase in malondialdehyde and reactive species, decrease in the activity of the superoxide dismutase and catalase, which possibly culminated in the reduction of cell viability. Thus, it is important to emphasize that BPA developed atypical behaviors in Drosophila melanogaster, reinforce the importance of the environmental factor in the development of neurobehavioral diseases.

Abstract
Neurodevelopmental disorders, such as Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD) are responsible for behavioral deficits in children. Imidacloprid is a nicotinic acetylcholine receptor agonist, capable of causing behavioral changes in Drosophila melanogaster, similar to the ADHD-like phenotypes. We assess whether behavioral damage induced by imidacloprid exposure in Drosophila melanogaster is associated with neurochemical changes and whether these changes are similar to those observed in neurodevelopmental disorders such as ASD and ADHD. The fruit flies were divided into four groups, exposed to either a standard diet (control) or a diet containing imidacloprid (200, 400 or 600 ρM) and allowed to mate for 7 days. After hatching, the progeny was subjected to in vivo and ex vivo tests. The ones exposed to imidacloprid showed an increase in hyperactivity, aggressiveness, anxiety and repetitive movements, as well as, a decrease in social interaction. Furthermore, exposure to imidacloprid decreased dopamine levels, cell viability and increased oxidative stress in the flies' progeny. These results demonstrated that the behavioral damage induced by imidacloprid exposure involves a reduction in dopamine levels and oxidative stress and that these neurochemical changes are in line with the events that occur in ASD and ADHD-like phenotypes in other models.

Abstract
Chronic unpredictable mild stress (CUMS) is a valid model for inducing depression-like symptoms in animal models, causing predictive behavioral, neurochemical, and physiological responses to this condition. This work aims to evaluate the possible antidepressant effect of γ-oryzanol (ORY) in the CUMS-induced depressive model in male Drosophila melanogaster. We will use the CUMS protocol to continue the study previously conducted by our research group, mimicking a depressive state in these insects. Male flies were subjected to various stressors according to a 10-day randomized schedule and concomitantly treated with ORY or fluoxetine (FLX). After the experimental period, in vivo behavioral tests were performed (open field, forced swimming, aggressiveness test, mating test, male virility, sucrose preference index and light/dark test) and ex vivo analyses measuring serotonin (5HT), dopamine (DA), octopamine (OCT) levels and body weight. We report here that ORY-treated flies and concomitant exposure to CUMS did not exhibit obvious behaviors such as prolonged immobility or increased aggressive behavior, reduced male mating and virility behavior, and anxiolytic behavior, in contrast to ORY, not altering sucrose preference and body weight flies exposed to CUMS. ORY effectively prevented 5HT and OCT reduction and partially protected against DA reduction. The data presented here are consistent and provide evidence for the use of ORY as a potential antidepressant compound.Lay SummaryFlies treated with ORY and concomitant exposure to CUMS did not exhibit obvious depressive-like behaviors, such as prolonged immobility in the FST or increased aggressive behavior, or reduced mating behavior, male virility, or anxiolytic behavior. ORY did not change the preference for sucrose and body weight of flies, about the levels of monoamines in the heads of flies, ORY was effective in preventing the reduction of 5HT and OCT, and we had partial protection of ORY for reducing the levels of DA.

Abstract
Iron (Fe) is used in various cellular functions, and a constant balance between its uptake, transport, storage, and use is necessary to maintain its homeostasis in the body. Changes in Fe metabolism with a consequent overload of this metal are related to neurological changes and cover a broad spectrum of diseases, mainly when these changes occur during the embryonic period. This work aimed to evaluate the effect of exposure to Fe overload during the embryonic period of Drosophila melanogaster. Progenitor flies (male and female) were exposed to ferrous sulfate (FeSO4) for ten days in concentrations of 0.5, 1, and 5 mM. After mating and oviposition, the progenitors were removed and the treatment bottles preserved, and the number of daily hatches and cumulative hatching of the first filial generation (F1) were counted. Subsequently, F1 flies (separated by sex) were subjected to behavioral tests such as negative geotaxis test, open field test, grooming, and aggression test. They have evaluated the levels of dopamine (DA), serotonin (5-HT), octopamine (OA), tryptophan and tyrosine hydroxylase (TH), acetylcholinesterase, reactive species, and the levels of Fe in the progenitor flies and F1. The Fe levels of F1 flies are directly proportional to what is incorporated during the period of embryonic development; we also observed a delay in hatching and a reduction in the number of the hatch of F1 flies exposed during the embryonic period to the 5mM Fe diet, a fact that may be related to the reduction of the cell viability of the ovarian tissue of progenitor flies. The flies exposed to Fe (1 and 5 mM) showed an increase in locomotor activity (hyperactivity) and a significantly higher number of repetitive movements. In addition to a high number of aggressive encounters when compared to control flies. We can also observe an increase in the levels of biogenic amines DA and 5-HT and an increase in TH activity in flies exposed to Fe (1 and 5 mM) compared to the control group. We conclude that the hyperactive-like behavior demonstrated in both sexes by F1 flies exposed to Fe may be associated with a dysregulation in the levels of DA and 5-HT since Fe is a cofactor of TH, which had its activity increased in this study. Therefore, more attention is needed during the embryonic development period for exposure to Fe overload.

Abstract
Parkinson's is a neurodegenerative disease, characterized by the loss of dopaminergic neurons, cholinergic alterations and oxidative damages. Lutein is widely known by its antioxidants properties. In the present study, we investigated whether lutein-loaded nanoparticles protects against locomotor damage and neurotoxicity induced by Parkinson's disease model in Drosophila melanogaster, as well as possible mechanisms of action. First, the nanoparticles were characterized by physicochemical methods, demonstrating that water affinity was improved by the encapsulation of lutein into the polymeric encapsulant matrix. The fruit flies of 1-4 days old were divided into four groups and exposed to a standard diet (control), a diet containing either rotenone (500 μM), lutein-loaded nanoparticles (6 μM) or rotenone (500 μM) and lutein-loaded nanoparticles (6 μM) for 7 days. The survival percentage was assessed, the flies were submitted to negative geotaxis, open field tasks and the determination of dopamine levels, tyrosine hydroxylase (TH) and acetylcholinesterase activities and oxidative stress indicators (superoxide dismutase, catalase, thiobarbituric acid reactive substances and glutathione S-transferase) were carried out. The exposure to lutein-loaded nanoparticles protected against locomotor damage and the decrease survival rate induced by rotenone, besides, it restored the dopamine levels, TH and acetylcholinesterase activities and oxidative stress indicators. These results provide evidence that lutein-loaded nanoparticles are an alternative treatment for rotenone-induced damage, and suggest the involvement of dopaminergic and cholinergic system and oxidative stress.

Abstract
The goals of this work were to evaluate the effects produced by a hyperglycidic diet (HD) on Drosophila melanogaster and to verify the protective effect of 7-chloro-4-(phenylselanyl) quinoline (4-PSQ) on this model. Adult flies were divided into eight groups of 50 flies each: (1) RD, (regular diet) (2) RD + 4-PSQ (25 μM), (3) HD 5%, (4) HD 10%, (5) HD 30% (6) HD 5% + 4-PSQ (25 μM), (7) HD 10% + 4-PSQ (25 μM) and (8) HD 30% + 4-PSQ (25 μM). Flies were exposed to a diet containing sucrose and or 4-PSQ for ten days, according to each group. At the end of treatment survival rate, longevity, hatch rate, food intake, glucose and triglyceride levels, as well as, some markers of oxidative stress, such as thiobarbituric acid reactive substances (TBARS), superoxide dismutase (SOD) and catalase (CAT) activities, protein thiol (PSH) and non-protein levels (NPSH) and cell viability assays (Resazurin and MTT) were evaluated. It was observed that HD's consumption was associated with lower survival of the flies, lower longevity, and increased levels of glucose, triglycerides, TBARS and increased SOD activities and CAT activities. Treatment with 25 μM 4-PSQ increased the satiety of flies, increased survival, reduced glucose, triglyceride and TBARS levels, increased hatching, and normalized SOD and CAT activities. These results suggest that 25 μM 4-PSQ had a potential antioxidant effect and provided greater satiety by attenuating the effects of high HD consumption on this model.

Abstract
This study aimed to evaluate the effects of the addition of saturated fat and hydrogenated vegetable fat (HVF) to the diet on depressive and anxiety-like behaviors in Drosophila melanogaster. Flies were exposed to experimental diets: regular diet (RD), or HVF in the concentrations of the substitute (SHVF), HVF 10% and HVF 20%, or Lard (L) in the concentrations of the substitute (SL), L 10% and L 20%, during seven days. Our results showed that flies fed with the HVF diet presented similar behaviors to depression, anxiety, and a higher number of aggressive events. Flies exposed to L showed only depressive-like behavior. Regarding serotonin levels (5HT), there was a significant reduction in the flies exposed to SHVF, HVF 10%, HVF 20%, and L 20%. Regarding the levels of octopamine (OA), there was a significant reduction in the flies exposed to both HVF and L rich diets when compared with the RD group. Also, there was a significant negative correlation between 5HT or OA levels and behaviors of aggressiveness, negative geotaxis, immobility time, light/dark, and grooming in the flies. This study shows that D. melanogaster can serve as a valuable model for understanding psychiatric disorders and that the type of fatty acid (FA) offered in the diet can influence these disorders. This demonstrates the importance of the composition of the FAs in the neural pathways, being able to influence the signaling of neurotransmitters, such as 5HT and OA, and thus, cause behavioral changes.

Abstract
Abnormalities in the thyroid hormones, like in hypothyroidism, are closely related to dementia and Alzheimer's disease demonstrating the main symptom of these disorders: memory deficit. In this study we evaluated the effect of chrysin on deficit spatial and aversive memories and the contribution of glutamatergic, cholinergic pathways and Na+, K+-ATPase activity on hippocampus and prefrontal cortex in hypothyroid adult female mice C57BL/6. Hypothyroidism was induced by the continuous exposure to 0.1% methimazole (MTZ) in drinking water for 31 days. The exposure to MTZ was associated to low plasma levels of thyroid hormones (TH) compared to the control group on the 32nd. Subsequently, euthyroid and MTZ-induced hypothyroid mice received (intragastrically) either vehicle or chrysin (20 mg/kg) once a day for 28 consecutive days. After treatments mice performed the following behavioral assessments: open-field test (OFT), morris water maze (MWM) and passive avoidance test. Additionally, plasma TH levels were measured again, as well as glutamate levels, Na+,K+-ATPase and acetylcholinesterase (AChE) activities were analyzed in the hippocampus and prefrontal cortex of mice. Mice with hypothyroidism showed a deficit of spatial and aversive memory and chrysin treatment reversed these deficits. It also reduced the levels of glutamate and decreased Na+,K+-ATPase activity in both cerebral structures in the hypothyroid mice compared with the euthyroid ones, with the exception of glutamate in the hippocampus, which was a partial reversal. AChE activity was not altered by treatments. Together, our results demonstrate that chrysin normalized hippocampal glutamate levels and Na+,K+-ATPase activity, which could be involved in the reversal of memory deficit.

Abstract
The clinical use of paclitaxel as a chemotherapeutic agent is limited by the severe acute and chronic hypersensitivity caused when it is administered via intraperitoneal or intravenous routes. Thus far, evidence has suggested that transient receptor potential vanilloid-1 (TRPV1) has a key role in the chronic neuropathy induced by paclitaxel. Despite this, the role of TRPV1 in paclitaxel -related acute nociception, especially the development of visceral nociception, has not been evaluated. Thus, the goal of this study was to evaluate the participation of TRPV1 in a model of acute nociception induced by paclitaxel in rats and mice. A single intraperitoneal (i.p.) paclitaxel administration (1 mg/kg, i.p.) produced an immediate visceral nociception response 1 h after administration, caused mechanical and heat hypersensitivity, and diminished burrowing behaviour 24 h after administration. These nociceptive responses were reduced by SB-366791 treatment (0.5 mg/kg, i.p., a TRPV1 antagonist). In addition, TRPV1-positive sensory fibre ablation (using resiniferatoxin, 200 µg/kg, s.c.) reduced visceral nociception and mechanical or heat hypersensitivity caused by paclitaxel injection. Similarly, TRPV1 deficient mice showed a pronounced reduction in mechanical allodynia to paclitaxel acute injection and did not develop heat hypersensitivity. Moreover, 24 h after its injection, paclitaxel induced chemical hypersensitivity to capsaicin (a TRPV1 agonist, 0.01 nmol/site) and increased TRPV1 immunoreactivity in the dorsal root ganglion and sciatic nerve. In conclusion, TRPV1 is involved in mechanical and heat hypersensitivity and spontaneous-pain behaviour induced 24 h after a single paclitaxel injection. This receptor is also involved in visceral nociception induced immediately after paclitaxel administration.

Abstract
Spermine and spermidine are natural polyamines that are produced mainly via decarboxylation of l-ornithine and the sequential transfer of aminopropyl groups from S-adenosylmethionine to putrescine by spermidine synthase and spermine synthase. Spermine and spermidine interact with intracellular and extracellular acidic residues of different nature, including nucleic acids, phospholipids, acidic proteins, carboxyl- and sulfate-containing polysaccharides. Therefore, multiple actions have been suggested for these polycations, including modulation of the activity of ionic channels, protein synthesis, protein kinases, and cell proliferation/death, within others. In this review we summarize these neurochemical/neurophysiological/morphological findings, particularly those that have been implicated in the improving and deleterious effects of spermine and spermidine on learning and memory of naïve animals in shock-motivated and nonshock-motivated tasks, from a historical perspective. The interaction with the opioid system, the facilitation and disruption of morphine-induced reward and the effect of polyamines and putative polyamine antagonists on animal models of cognitive diseases, such as Alzheimer's, Huntington, acute neuroinflammation and brain trauma are also reviewed and discussed. The increased production of polyamines in Alzheimer's disease and the biphasic nature of the effects of polyamines on memory and on the NMDA receptor are also considered. In light of the current literature on polyamines, which include the description of an inborn error of the metabolism characterized by mild-to moderate mental retardation and polyamine metabolism alterations in suicide completers, we can anticipate that polyamine targets may be important for the development of novel strategies and approaches for understanding the etiopathogenesis of important central disorders and their pharmacological treatment.

Abstract
Sympathetic fibres maintain some forms of neuropathic pain, but the underlying mechanisms are poorly understood. Therefore, this study investigated the possible involvement of transient receptor potential ankyrin 1 (TRPA1) and the role of the sympathetic nervous system (involved in sympathetically maintained neuropathic pain) in a model of neuropathic pain induced by sciatic nerve chronic constriction injury (CCI) in mice. Systemic injection of the selective TRPA1 antagonist HC-030031 reversed the mechanical and cold allodynia that was induced by sciatic nerve chronic constriction injury (CCI). Nerve injury also sensitised mice to nociception, which was induced by the intraplantar injection of a low dose of the TRPA1 agonist allyl isothiocyanate without changing TRPA1 immunoreactivity in the injected paw. Furthermore, chemical sympathectomy produced by guanethidine largely prevented CCI-induced mechanical and cold allodynia. CCI also induced a norepinephrine-triggered nociception that was inhibited by an α-adrenoceptor antagonist, norepinephrine transporter block and monoamine oxidase inhibition. Finally, the peripheral injection of HC-030031 also largely reduced CCI-induced norepinephrine nociception and mechanical or cold allodynia. Taken together, the present findings reveal a critical role of TRPA1 in mechanical and cold hypersensitivity and norepinephrine hypersensitivity following nerve injury. Finally, our results suggest that TRPA1 antagonism may be useful to treat patients who present sympathetically maintained neuropathic pain.

Abstract
Acute gout attacks produce severe joint pain and inflammation associated with monosodium urate (MSU) crystals leading to oxidative stress production. The transient potential receptor ankyrin 1 (TRPA1) is expressed by a subpopulation of peptidergic nociceptors and, via its activation by endogenous reactive oxygen species, including hydrogen peroxide (H2O2), contributes to pain and neurogenic inflammation. The aim of this study was to investigate the role of TRPA1 in hyperalgesia and inflammation in a model of acute gout attack in rodents. Inflammatory parameters and mechanical hyperalgesia were measured in male Wistar rats and in wild-type (Trpa1(+/+)) or TRPA1-deficient (Trpa1(-/-)) male mice. Animals received intra-articular (ia, ankle) injection of MSU. The role of TRPA1 was assessed by receptor antagonism, gene deletion or expression, sensory fiber defunctionalization, and calcitonin gene-related peptide (CGRP) release. We found that nociceptor defunctionalization, TRPA1 antagonist treatment (via ia or oral administration), and Trpa1 gene ablation abated hyperalgesia and inflammatory responses (edema, H2O2 generation, interleukin-1β release, and neutrophil infiltration) induced by ia MSU injection. In addition, we showed that MSU evoked generation of H2O2 in synovial tissue, which stimulated TRPA1 producing CGRP release and plasma protein extravasation. The MSU-elicited responses were also reduced by the H2O2-detoxifying enzyme catalase and the reducing agent dithiothreitol. TRPA1 activation by MSU challenge-generated H2O2 mediates the entire inflammatory response in an acute gout attack rodent model, thus strengthening the role of the TRPA1 receptor and H2O2 production as potential targets for treatment of acute gout attacks.

Abstract
The transient receptor potential ankyrin 1 (TRPA1) is expressed in peripheral and spinal terminals of sensory neurons, jointly to the vanilloid receptor (TRPV1). A relevant peripheral role of TRPA1 receptor has been implicated in a variety of processes, including the detection of noxious cold, and diverse painful stimulus, but the functional role of TRPA1 receptor in nociceptive transmission at spinal cord in vivo is poorly known. Therefore, the aim of this study was to evaluate whether the glutamatergic system is involved in the transmission of nociceptive stimulus induced for a TRPA1 agonist in the rat spinal cord. We observed that cinnamaldehyde, a TRPA1 agonist, on spinal cord synaptosomes leads to an increase in [Ca(2+)](i) and a rapid release of glutamate, but was not able to change the specific [(3)H]-glutamate binding. In addition, spinally administered cinnamaldehyde produced heat hyperalgesia and mechanical allodynia in rats. This behavior was reduced by the co-injection (i.t.) of camphor (TRPA1 antagonist) or MK-801 (N-methyl-D-aspartate (NMDA) receptor antagonist) to cinnamaldehyde. Besides, the pretreatment with resiniferatoxin (RTX), a potent TRPV1 agonist, abolished the cinnamaldehyde-induced heat hyperalgesia. Here, we showed that intrathecal RTX results in a decrease in TRPA1 and TRPV1 immunoreactivity in dorsal root ganglion. Collectively, our results demonstrate the pertinent participation of spinal TRPA1 in the possible enhancement of glutamatergic transmission of nociceptive signals leading to increase of the hypersensitivity, here observed as heat hyperalgesia. Then the modulation of spinal TRPA1 might be a valuable target in painful conditions associated with central pain hypersensitivity.

Abstract
Although Creatine (Cr) and Phosphocreatine (PCr) systems play a key role in cellular energy and energy transport in neuronal cells, its implications for learning and memory are still controversial. Thus, we decided to investigate the involvement of cAMP-dependent protein kinase A (PKA), Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) and cAMP responsive element binding protein (CREB) in the spatial consolidation after an intrahippocampal injection of Cr. Statistical analysis revealed that Cr (2.5 nmol/hippocampus) (post-training) decreased the latency for escape and the mean number of errors on Barnes maze test. Post-training co-administration of the PKA inhibitor (H-89 25 ρmol/hippocampus) did not alter the facilitatory effect of Cr in this memory test. On the other hand, Cr-induced spatial retention was reverted by co-administration of the CaMKII inhibitor (STO-609 5 nmol/hippocampus). Neurochemical analysis revealed that intrahippocampal injection of Cr, when analyzed after 30 min rather than after 3 h, increased the levels of pCREB and pCaMKII but not pPKA levels. Statistical analysis also revealed that the post-training co-administration of STO-609 but not H-89 reversed the increase of pCREB levels induced by Cr. The results presented in this report suggest that intracellular CaMKII/CREB pathway plays a key role in the Cr-induced spatial retention. Thus, it is plausible to propose that Cr plays a putative role as a neuromodulator in the brain, and that at least some of its effects may be mediated by intracellular CaMKII/CREB pathway.

Abstract
Polyamines (putrescine, spermidine and spermine) are important endogenous regulators of ion channels, such as vanilloid (TRPV1), glutamatergic (NMDA or AMPA/kainate) and acid-sensitive (ASIC) receptors. In the present study, we have investigated the possible nociceptive effect induced by polyamines and the mechanisms involved in this nociception in vivo. The subcutaneous (s.c.) injection of capsaicin (as positive control), spermine, spermidine or putrescine produced nociception with ED(50) of 0.16 (0.07-0.39)nmol/paw, 0.4 (0.2-0.7) μmol/paw, 0.3 (0.1-0.9) μmol/paw and 3.2 (0.9-11.5) μmol/paw, respectively. The antagonists of NMDA (MK801, 1 nmol/paw), AMPA/kainate (DNQX, 1 nmol/paw) or ASIC receptors (amiloride, 100 nmol/paw) failed to reduce the spermine-trigged nociception. However, the TRPV1 antagonists capsazepine or SB366791 (1 nmol/paw) reduced spermine-induced nociception, with inhibition of 81 ± 10 and 68 ± 9%, respectively. The previous desensitization with resiniferatoxin (RTX) largely reduced the spermine-induced nociception and TRPV1 expression in the sciatic nerve, with reductions of 82 ± 9% and 67 ± 11%, respectively. Furthermore, the combination of spermine (100 nmol/paw) and RTX (0.005 fmol/paw), in doses which alone were not capable of inducing nociception, produced nociceptive behaviors. Moreover, different concentrations of spermine (3-300 μM) enhanced the specific binding of [(3)H]-RTX to TRPV1 receptor. Altogether, polyamines produce spontaneous nociceptive effect through the stimulation of TRPV1, but not of ionotropic glutamate or ASIC receptors.

Abstract
AIMS In the present work, we characterize the inflammatory process induced by the topical application of cinnamaldehyde on the skin of mice and verify the participation of transient receptor potential A1 TRPA1 receptors in this process. MAIN METHODS We measured mouse ear edema and sensitization/desensitization after topical application of cinnamaldehyde or/and capsaicin. We also quantified cellular infiltration through myeloperoxidase (MPO) activity and histological and immunohistochemical analyses and evaluated the expression of TRPV1 and TRPA1 by western blot. KEY FINDINGS Cinnamaldehyde induced ear edema in mice (1-6μg/ear) with a maximum effect of 4μg/ear. Cinnamaldehyde promoted leukocyte infiltration as detected by increasing MPO activity and confirmed by histological analyses. The edema and cellular infiltration evoked by the application of 4μg/ear of cinnamaldehyde were prevented by topical application of ruthenium red, a non-selective TRP antagonist as well as camphor and HC030031, two TRPA1 receptor antagonists. Cinnamaldehyde-induced edema, but not cellular infiltration, was prevented by topical application of the tachykinin NK1 antagonist, aprepitant, indicating a neuropeptide release phenomenon in this process. Additionally, we observed that repeated topical applications of cinnamaldehyde did not induce changes in sensitization or desensitization with respect to the edema response. Interestingly, repeated treatment with the TRPV1 agonist, capsaicin, abrogated it edematogenic response, confirming the desensitization process and partially decreasing the cinnamaldehyde-induced edema, suggesting the involvement of capsaicin-sensitive fibers. SIGNIFICANCE Our data demonstrate that the topical application of cinnamaldehyde produces an inflammatory response that is dependent on TRPA1 receptor stimulation.

Abstract
RATIONALE Spermidine (SPD) is an endogenous polyamine that modulates N-methyl-D: -aspartate receptor functions, which has been reported to facilitate memory formation. OBJECTIVES In the current study, we investigated the involvement of nitric oxide in the facilitatory effect of SPD on the memory of adult male Wistar rats in the inhibitory avoidance task. RESULTS The coadministration of the nonspecific NOS inhibitor N (G) nitro-L: -arginine methyl ester (L: -NAME) (0.1 nmol, intrahippocampus) with spermidine (0.2 nmol), immediately after training, prevented the memory improvement caused by spermidine in the avoidance inhibitory task. Spermidine increased nitrite and nitrate levels (NO(X)) in the hippocampus 30 min after its administration, and L: -NAME coinjection prevented the stimulatory effect of spermidine on NO(X) levels. The systemic injection of 7-nitroindazole (30 mg/kg, i.p.), 30 min before training, impaired memory and did not prevent spermidine-induced increase of NO(X) levels in the hippocampus. CONCLUSIONS These results suggest that memory enhancement by spermidine is prevented by the nonspecific nitric oxide synthase inhibitor L: -NAME.

Abstract
The polyamines, spermine, spermidine, and putrescine, are a group of aliphatic amines that may act as physiological modulators of N-methyl-D-aspartate (NMDA) receptors. Although the modulatory role of polyamines in NMDA receptor function has long been known, the effects of polyamines on learning and memory only recently began to be unraveled. In the present study, we investigated the effect of bilateral infusions of spermidine (0.02-2 nmol), a polyamine agonist, into the CA1 region of the rat dorsal hippocampus on inhibitory avoidance learning 30 min pre-training, immediately post-training, 6 h post-training, or 10 min pre-test. Bilateral microinjections of 0.2 nmol spermidine prolonged step-down latencies compared to the respective control group when administered 30 min pre-training or immediately post-training. These results provide evidence that the modulatory effects of spermidine on the acquisition and/or early consolidation of memory of inhibitory avoidance tasks in the hippocampus occur within a limited time window.

Abstract
DESIGN This study was designed to evaluate, in a cohort of 1039 middle-aged men, the interaction between the duration and intensity of physical activity performed either during leisure time (competitive sports, walking, cycling) or work, and principal coronary disease risk factors. METHOD A cohort of subjects aged 45-64 years were recruited in 1993. Subjects included both individuals who were physically active and those who were sedentary, and were age-matched. RESULTS Leisure time physical activity was inversely related to levels of total cholesterol, triglycerides, and fibrinogen, and to diastolic and systolic blood pressure. High-density lipoprotein cholesterol level was directly related to leisure time activity. Working activity, even if strenuous, was not related to risk profile. Leisure time activity did not favorably influence lipid levels in smokers, obese subjects or those with known dyslipidemia. CONCLUSIONS This study further reinforces the use of continuous diet and drug treatment in dyslipidemic subjects and in smokers, who have to refrain from smoking if they are to benefit fully from the effects of physical activity.
