Adebayo OL, Agu VA, Idowu GA, Ezejiaku BC, Atunnise AK. The Role of Vitamin C on ATPases Activities in Monosodium Glutamate-Induced Oxidative Stress in Rat Striatum and Cerebellum. Neurotox Res 2024; 42:40. [PMID: 39212807 DOI: 10.1007/s12640-024-00719-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 06/04/2024] [Accepted: 08/15/2024] [Indexed: 09/04/2024]
Abstract
Monosodium glutamate (MSG) is a silent excitotoxin used as a flavour enhancer but exerts serious health hazards to consumers. MSG plays a role in neuronal function as the dominant excitatory neurotransmitter. It is transferred into the blood and ultimately increases brain glutamate levels, causing functional disruptions notably via oxidative stress. The study evaluated the toxic effect of high consumption of MSG and the modulatory role of vitamin C on ATPase activities in the striatum and cerebellum of male Wistar rats for five weeks. Rats were grouped into four (A-D): group A was fed with rat's show only; Group B was fed with diet containing 15% MSG; Group C was treated with vitamin C (200 mg/kg b.wgt orally in 0.9% saline solution) only for 3 weeks; and group D rats were fed with MSG and vitamin C. The findings show that MSG does not affect body and cerebellum weights but increases striatal weight. MSG increases the malondialdehyde (MDA) level and significantly decreases catalase (CAT) and superoxide dismutase (SOD) activities and glutathione (GSH) levels. MSG significantly impaired striatal and cerebellar ATPases activities (Na+/K+-, Ca2+-, Mg2+- and total ATPases). Vitamin C treatment abolishes MSG-induced oxidative stress and improves ATPase activities. The findings show that vitamin C has beneficial effects in improving the functions of membrane-bound ATPases against MSG toxicity in rat's striatum and cerebellum.

Abstract
Objective: Bipolar disorder (BD) is a challenging psychiatric disorder and a complex disease. The associated reduction in serum vitamin D3 (VitD3) levels in BD patients and the contribution of zinc (Zn) to the treatment, along with the severe side effects of lithium (Li) treatment, were encouraging to assess the efficacy of different correlated combinations of therapeutic/nutraceutical treatments such as olanzapine (Oln), VitD3, and Zn against Li. Methods: Mania was induced in C57BL/6 mice by administering methylphenidate (MPH) for 14 consecutive days. On the 8th day of MPH injection, different treatment regimens were administered, Li, Oln, VitD3/Zn, VitD3/Zn/Oln, VitD3 + Zn + Oln + Li50mg/kg (C50), and VitD3 + Zn + Oln + Li100mg/kg (C100). Both VitD3 (850 IU/kg) and Zn (180 mg/kg) were supplied with food for 2 weeks before starting the induction of mania, which continued until the end of MPH administration. Behavioral, brain oxidative stress, thyroid hormones, VitD3, Zn, GsK-3β, and Bcl2 levels, as well as brain histopathological alterations, were assessed. Results: Manic mice exhibited alterations in all tested parameters, and the histopathological examination of the cortex and hippocampus confirmed these results. The VitD3/Zn/Oln, C50, and C100 treatment regimens reversed most of the behavioral and pathophysiological alterations; however, the C50 treatment regimen was the most efficient. Conclusions: This study emphasizes the importance of combining different antimanic medications like Li and Oln with nutraceutical supplements to increase their antimanic efficacy, reduce their adverse effects, and, ideally, improve the BD patient's quality of life.

Abstract
Protein diets are required for the normal development of the reproductive system and their inadequacy or deficiency might have hazardous functional complications during maturational and developmental stages. The study was carried out to evaluate the effect of selenium (Se) and zinc (Zn) supplementation on the male and female reproductive organs of rats with postnatal protein malnutrition. Male and female weanling rats were randomly assigned to six groups respectively. The adequate protein diet rats were fed with 16% casein diet while the protein malnourished diet (PMD) rats were fed with 5% casein diet. After the 8th week of feeding, Se (sodium selenite; Na2SeO3) and Zn (zinc sulfate; ZnSO4·7H2O) were supplemented for 3 weeks. The growth curve of body weights, lipid profile, testosterone and progesterone level, Na+-K+-ATPase activity, oxidative stress, and antioxidant status were evaluated. The results showed that PMD reduced the body weights of male and female rats. It also reduced the activities of catalase and glutathione peroxidase in the testes, but reductions in superoxide dismutase and glutathione-S-transferase activities, glutathione, vitamins C and E, testosterone, and progesterone levels were observed in both the testes and ovaries. Furthermore, PMD increased the nitric oxide level in both organs and altered the plasma lipid profiles in both sexes. Se and Zn supplementation, however, restored almost all the alterations observed in all the parameters analyzed. In conclusion, Se and Zn supplementation protects the male and female reproductive organs of rats against postnatal protein malnutrition.

Abstract
Proteins are required for biological functions and their inadequacy might impair the growth and development of the reproductive system. The study investigated the effects of fish oil (FO) supplementation on low-protein diet-induced alterations in male and female reproductive organs. Male and female rats were assigned randomly to four groups respectively. The NPD rats had five rats per group and were given 16% casein diet while the LPD rats had eight rats per group and received 5% casein diet. After the 8th week, FO was administered for 3 weeks via oral gavage at a concentration of 400mg Kg-1 after which the rats were sacrificed and testes and ovaries were excised. LPD-fed rats showed lower body weights for both genders. In LPD-fed rats, NO was significantly increased while GSH, vitamins C and E levels, the activities of CAT (except in ovaries), and GST were significantly reduced in both tissues. The activities of SOD and GPx were only reduced in the testes including sperm count, motility, and increase deformed sperm cells. Testosterone and progesterone levels were also reduced and lipid homeostasis was disrupted in the plasma of LPD-fed rats. FO supplementation reduces the NO, CHOL, TG, LDL (in females), and VLDL but significantly improves HDL (in females), testosterone, and progesterone levels, sperm count, motility, and morphology. The antioxidant status of both tissues also increased significantly in LPD-fed rats. Conclusively, FO might be effective in improving testicular and ovarian functions and for the maintenance of plasma lipid homeostasis in LPD-fed rats.

Zinc(II) - Syringic acid complexation synergistically exerts antioxidant action and modulates glucose uptake and utilization in L-6 myotubes and rat muscle tissue. Biomed Pharmacother 2022; 154:113600. [PMID: 36037784 DOI: 10.1016/j.biopha.2022.113600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Revised: 08/15/2022] [Accepted: 08/21/2022] [Indexed: 11/15/2022] Open
Abstract
Zinc and syringic acid have metabolic and antioxidant medicinal potentials. A novel zinc(II)-syringic acid complex with improved anti-hyperglycaemic and antioxidant potential was developed. Zinc(II) was complexed with syringic acid in a 1:2 molar ratio and characterized using FT-IR, 1H NMR and LC-MS. Different experimental models were used to compare the anti-hyperglycaemic and antioxidant properties between the complex and precursors. A Zn(II)-bisyringate.2H2O complex was formed. The in vitro radical scavenging and Fe3+ reducing antioxidant, antiglycation, and α-glucosidase inhibitory activities of the complex were 1.8-5.2 folds stronger than those of the syringic acid precursor and comparable to those of the positive controls. The complex possessed an increased ability to inhibit lipid peroxidation (by 1.6-1.7 folds) and glutathione depletion (2.8-3 folds) relative to syringic acid in Chang liver cells and liver tissues isolated from rats. The complex exhibited a higher glucose uptake effect (EC50 = 20.4 and 386 µM) than its precursors (EC50 = 71.1 and 6460 µM) in L6-myotubes and psoas muscle tissues isolated from rats, respectively, which may be linked to the observed increased cellular zinc uptake potentiated by complexation. Tissue glucose uptake activity was accompanied by increased hexokinase activity, suggesting increased glucose utilization. Moreover, treatment increased tissue phospho-Akt/pan-Akt ratio. The complex had strong molecular docking scores than syringic acid with target proteins linked to diabetes. The presence of two syringic acid moieties and Zn(II) in the complex influenced its potency. The complex was not hepatotoxic and myotoxic in vitro. Zinc-syringic acid complexation may be a novel promising therapeutic approach for diabetes and oxidative complications.

Abstract
OBJECTIVES Our aim was to synthesize, characterize and evaluate the antihyperglycaemic and anti-oxidative properties of a new Zn(II) complex of vanillic acid. METHODS The complex was synthesized using ZnSO4.7H2O and vanillic acid as precursors. NMR and FTIR techniques were used to characterize the synthesized complex. The cytotoxicity of the complex was measured. The antihyperglycemic and anti-oxidative properties of the complex were evaluated using in vitro, cell-based and ex vivo models and compared with those of its precursors. KEY FINDINGS Zn(II) coordinated with vanillic acid via a Zn(O6) coordination, with the complex having three moieties of vanillic acid. The radical scavenging, Fe3+ reducing and hepatic antilipid peroxidative activity of the complex were, respectively, 2.3-, 1.8- and 9.7-folds more potent than vanillic acid. Complexation increased the α-glucosidase and glycation inhibitory activity of vanillic acid by 3- and 2.6-folds, respectively. Zn(II) conferred potent L-6 myotube (EC50 = 20.4 μm) and muscle tissue (EC50 = 612 μm) glucose uptake effects on vanillic acid. Cytotoxicity evaluation showed that the complex did not reduce the viability of L-6 myotubes and Chang liver cells. CONCLUSIONS The data suggest that Zn(II)-vanillic acid complex had improved bioactivity relative to vanillic acid. Thus, Zn(II) may be further studied as an antihyperglycaemic and anti-oxidative adjuvant for bioactive phenolic acids.

Abstract
BACKGROUND/OBJECTIVES Adherence to a "Western" style dietary pattern has been related to behavior problems in children in high-income countries; however, dietary patterns may differ in countries undergoing the nutrition transition. Associations of dietary patterns with behavior problems in a Latin American context have not been evaluated. SUBJECTS/METHODS Mothers of 385 children 5 to 12 y old completed a food frequency questionnaire (FFQ) on the children's usual intake at enrollment into a cohort study. Four dietary patterns were identified through principal component analysis of the FFQ: animal protein, snacking, cheaper protein, and traditional/starch. After a median 6 y follow-up, adolescents reported behavior problems via the Youth Self Report, a standardized questionnaire. We compared the continuous distributions of externalizing and internalizing behavior problems and their subscales across quartiles of adherence to the four dietary patterns using multivariable linear regression. RESULTS Boys in the highest quartile of adherence to the animal protein pattern in middle childhood had an adjusted 5.5 units lower (95% CI -9.5, -1.5) mean total externalizing problems score compared with boys in the lowest quartile (P trend = 0.008). Adherence to the animal protein pattern was also inversely related to the aggressive behavior externalizing subscale in a dose-response manner among boys (P trend = 0.009). There were no associations between adherence to other dietary patterns and externalizing problems in boys or girls. There were no associations with internalizing problems. CONCLUSION Adherence to an animal protein dietary pattern in middle childhood was associated with less externalizing behavior problems in adolescent boys.

Zinc(II) mineral increased the in vitro, cellular and ex vivo antihyperglycemic and antioxidative pharmacological profile of p-hydroxybenzoic acid upon complexation. J Food Biochem 2021; 45:e13609.

Abstract
In this study, zinc was complexed with p-hydroxybenzoic acid to synthesize a complex with improved pharmacological profile. Proton NMR and FTIR analysis were used to characterize the complex. Several in vitro, cellular and ex vivo antihyperglycemic and antioxidative assays were used to evaluate the potency of the complex, relative to its precursors, while molecular docking was used to investigate interactions with insulin signaling targets (GLUT-4 and PKB). Also, the cytotoxicity of the complex was evaluated in Chang liver cells and L-6 myotubes using MTT assay. Complexation was through a Zn(O4 ) coordination. This afforded the complex two moieties of p-hydroxybenzoic acid, which influenced its activities. While the complex retained the α-glucosidase and α-amylase inhibitory activity of its phenolic acid precursor, complexation increased in vitro and ex vivo antioxidant activity of the phenolic acid by 1.4 to 10.5-folds. Complexation, further, conferred a potent antiglycation activity and L-6 myotube and psoas muscle glucose uptake properties (2.1 to 3.5-folds more than p-hydroxybenzoic acid) on the phenolic acid, without notably inhibiting or reducing the viability of Chang liver cells (IC50 = 5,120 μM) and L-6 myotubes (IC50 = 2,172 μM). Docking studies showed the complex had better interactions with insulin signaling targets (GLUT-4 and PKB) than p-hydrobenzoic acid, which may influence its glucose uptake effects. Data suggest that Zn(II) complexation improved and/or broadened the pharmacological profile of p-hydroxybenzoic acid, thus, may be further studied as a promising adjuvant for phenolic acids. PRACTICAL APPLICATIONS: Most antidiabetic drugs are used as two or more combinations to achieve better efficacy, which may cause drug interaction and increase the risk of side effects associated with these drugs. This study takes advantage of the glycemic control property of zinc and the antioxidant and/or diabetes-related pharmacological properties of p-hydroxybenzoic acid to form a complex with improved and broader antioxidant and antihyperglycemic profile and minimal toxicity concerns. With appropriate further studies, Zn(II)-phenolic acid complexes may be safe nutraceuticals for diabetes and related oxidative complications.

Abstract
CONTEXT Barium (Ba) may induce oxidative stress leading to tissues injury. OBJECTIVE Our study investigated the therapeutic efficiency of zinc (Zn) and selenium (Se) against neurotoxicity induced by Ba in adult rats and their progeny. MATERIAL AND METHODS Pregnant rats are exposed either to Ba (67 ppm), Ba + Zn, Ba + S or to only Zn and Se. RESULTS In Ba-treated rats, there was an increase of MDA, H2O2, AOPP levels and SOD activity in the cerebellum of dams and their pups, a decrease in GPx, CAT, AChE, Na+K+-ATPase and Mg2+-ATPase activities, GSH and NPSH levels. These changes were confirmed by histological damages. Co-administration of Zn or Se to Ba-treated rats ameliorated the biochemical and histological aspects. CONCLUSION Our results revealed that Zn and Se have shown promising effects against Ba toxicity in the cerebellum of adult rats and their suckling pups.

Abstract
Recent evidence highlighted a pathogenetic link between redox dysregulation and the early stages of psychosis. Indeed, an increasing number of studies have pointed toward an association between oxidative stress, both at central and peripheral levels, and first psychotic episode. Moreover, basal low antioxidant capacity has been shown to directly correlate with cognitive impairment in the early onset of psychosis. In this context, the possibility to use antioxidant compounds in first psychotic episode, especially as supplementation to antipsychotic therapy, has become the focus of numerous investigations on rodents with the aim to translate data on the possible effects of antioxidant therapies to large populations of patients, with a diagnosis of the first psychotic episode. In this review, we will discuss studies, published from January 1st, 2007 to July 31st, 2017, investigating the effects of antioxidant compounds on neuropathological alterations observed in different rodent models characterized by a cluster of psychotic-like symptoms reminiscent of what observed in human first psychotic episode. A final focus on the effective possibility to directly translate data obtained on rodents to humans will be also provided.

Abstract
Many studies have shown that a maternal low-protein diet increases the susceptibility of offspring to cardiovascular disease in later-life. Moreover, a lower incidence of cardiovascular disease in females than in males is understood to be largely due to the protective effect of high levels of estrogens throughout a woman's reproductive life. However, to our knowledge, the role of estradiol in moderating the later-life susceptibility of offspring of nutrient-deprived mothers to cardiovascular disease is not fully understood. The present study is aimed at investigating whether oxidative stress in the brainstem caused by a maternal low-protein diet administered during a critical period of fetal/neonatal brain development (i.e during gestation and lactation) is affected by estradiol levels. Female Wistar rat offspring were divided into four groups according to their mothers' diets and to the serum estradiol levels of the offspring at the time of testing: (1) 22 days of age/control diet: (2) 22 days of age/low-protein diet; (3) 122 days of age/control diet: (4) 122 days of age/low-protein diet. Undernutrition in the context of low serum estradiol compared to undernutrition in a higher estradiol context resulted in increased levels of oxidative stress biomarkers and a reduction in enzymatic and non-enzymatic antioxidant defenses. Total global oxy-score showed oxidative damage in 22-day-old rats whose mothers had received a low-protein diet. In the 122-day-old group, we observed a decrease in oxidative stress biomarkers, increased enzymatic antioxidant activity, and a positive oxy-score when compared to control. We conclude from these results that following a protein deficiency in the maternal diet during early development of the offspring, estrogens present at high levels at reproductive age may confer resistance to the oxidative damage in the brainstem that is very apparent in pre-pubertal rats.

Abstract
Considering the antioxidant properties of sodium selenite (Na2SeO3) and the involvement of oxidative stress events in paraquat-induced neurotoxicity, this study investigated the protective effect of dietary Na2SeO3 on biochemical and behavioral parameters of zebrafish exposed to paraquat (PQ). Fish were pretreated with a Na2SeO3 diet for 21 days and then PQ (20 mg/kg) was administered intraperitoneally with six injections for 16 days. In the novel tank test, the Na2SeO3 diet prevented the locomotor impairments, as well as the increase in the time spent in the top area of the tank, and the exacerbation of freezing episodes. In the preference for conspecifics and in the mirror-induced aggression (MIA) tasks, Na2SeO3 prevented the increase in the latency to enter the area closer to conspecifics and the agonistic behavior of PQ-treated animals, respectively. Na2SeO3 prevented the increase of carbonylated protein (CP), reactive oxygen species (ROS), and nitrite/nitrate (NOx) levels, as well as the decrease in non-protein thiols (NPSH) levels. Regarding the antioxidant enzymatic defenses, Na2SeO3 prevented the increase in catalase (CAT) and glutathione peroxidase (GPx) activities caused by PQ. Altogether, dietary Na2SeO3 improves behavioral and biochemical function impaired by PQ treatment in zebrafish, by modulating not only redox parameters, but also anxiety- and aggressive-like phenotypes in zebrafish.

Abstract
This study was carried out to assess the effects of Se supplementation on biomarkers of inflammation and oxidative stress in patients with diabetic nephropathy (DN). This randomised, double-blind, placebo-controlled clinical trial was conducted among sixty patients with DN. Patients were randomly divided into two groups to take either 200 µg/d Se supplements as Se yeast (n 30) or placebo (n 30) for 12 weeks. In unadjusted analyses, compared with the placebo, Se supplementation led to a significant reduction in high-sensitivity C-reactive protein (hs-CRP) (-1069·2 (sd 1752·2) v. -135·3 (sd 1258·9) ng/ml, P=0·02), matrix metalloproteinase-2 (MMP-2) (-612·3 (sd 679·6) v. +76·0 (sd 309·1) ng/ml, P<0·001) and plasma malondialdehyde (MDA) concentrations (-0·1 (sd 0·7) v. +0·4 (sd 0·9) µmol/l, P=0·01). In addition, a significant increase in plasma total antioxidant capacity (TAC) (+174·9 (sd 203·9) v. +15·8 (sd 382·2) mmol/l, P=0·04) was observed following supplementation with Se compared with the placebo. Subjects who received Se supplements experienced a borderline statistically significant decrease in serum protein carbonyl (PCO) levels (P=0·06) compared with the placebo. When we adjusted the analysis for baseline values of biochemical parameters, age and BMI, serum hs-CRP (P=0·14) and MDA levels (P=0·16) became non-significant, whereas plasma nitric oxide (NO) (P=0·04) and glutathione (GSH) (P<0·001) became statistically significant, and other findings did not change. Supplementation with Se had no significant effect on NO, transforming growth factor β (TGF-β), advanced glycation end products (AGE), PCO and GSH compared with the placebo. Overall, our study demonstrated that Se supplementation among DN patients had favourable effects on serum MMP-2, plasma NO, TAC and GSH, but did not affect hs-CRP, TGF-β, AGE, PCO and MDA.

Abstract
AIMS Selenium (Se) and zinc (Zn) are trace elements required for optimal brain functions. Thus, the role of Se and Zn against protein malnutrition induced oxidative stress on mitochondrial antioxidants and electron transport chain (ETC) enzymes from rats' brain were investigated. MAIN METHODS Normal protein (NP) and low protein (LP) rats were fed with diets containing 16% and 5% casein respectively for a period of 10weeks. Then the rats were supplemented with Se and Zn at a concentration of 0.15mgL(-1) and 227mgL(-1) in drinking water for 3weeks after which the rats were sacrificed. KEY FINDINGS The results obtained from the study showed significant (p<0.05) increase in lipid peroxidation (LPO), ROS production, oxidized glutathione (GSSG) levels and mitochondrial swelling and significant (p<0.05) reductions in catalase (CAT) and Mn-superoxide dismutase (Mn-SOD) activities, glutathione (GSH) levels, GSH/GSSG ratio and MTT reduction as a result of LP ingestion. The activities of mitochondrial ETC enzymes were also significantly inhibited in both the cortex and cerebellum of LP-fed rats. Supplementation with either Se or Zn restored the alterations in all the parameters. SIGNIFICANCE The study showed that Se and Zn might be beneficial in protecting mitochondrial antioxidants and ETC enzymes against protein malnutrition induced oxidative stress.

Abstract
The roles of protein undernutrition as well as selenium (Se) and zinc (Zn) supplementation on the ability of calmodulin (CaM) to activate erythrocyte ghost membrane (EGM) Ca(2+)-ATPase and the calmodulin genes and protein expressions in rat's cortex and cerebellum were investigated. Rats on adequate protein diet and protein-undernourished (PU) rats were fed with diet containing 16% and 5% casein, respectively, for a period of 10 weeks. The rats were then supplemented with Se and Zn at a concentration of 0.15 and 227 mg l(-1), respectively, in drinking water for 3 weeks. The results obtained from the study showed significant reductions in synaptosomal plasma membrane Ca(2+)-ATPase (PMCA) activity, Ca(2+)/CaM activated EGM Ca(2+) ATPase activity and calmodulin genes and protein expressions in PU rats. Se or Zn supplementation improved the ability of Ca(2+)/CaM to activate EGM Ca(2+)-ATPase and protein expressions. Se or Zn supplementation improved gene expression in the cerebellum but not in the cortex. Also, the activity of PMCA was significantly improved by Zn. In conclusion, it is postulated that Se and Zn might be beneficial antioxidants in protecting against neuronal dysfunction resulting from reduced level of calmodulin such as present in protein undernutrition.

Abstract
Environmental stressors including protein malnutrition (PMN) during pre-, neo- and post-natal age have been documented to affect cognitive development and cause increased susceptibility to neuropsychiatric disorders. Most studies have addressed either of the three windows and that does not emulate the clinical conditions of intra-uterine growth restriction (IUGR). Such data fail to provide a complete picture of the behavioral alterations in the F1 generation. The present study thus addresses the larger window from gestation to F1 generation, a new model of intra-generational PMN. Naive Sprague Dawley (SD) dams pre-gestationally switched to LP (8% protein) or HP (20% protein) diets for 45 days were bred and maintained throughout gestation on same diets. Pups born (HP/LP dams) were maintained on the respective diets post-weaningly. The present study aimed to show the sex specific differences in the neurobehavioral evolution and behavioral phenotype of the HP/LP F1 generation pups. A battery of neurodevelopmental reflex tests, behavioral (Open field and forelimb gripstrength test), and cognitive [Elevated plus maze (EPM) and Morris water maze (MWM)] assays were performed. A decelerated growth curve with significantly restricted body and brain weight, delays in apparition of neuro-reflexes and poor performance in the LP group rats was recorded. Intra-generational PMN induced poor habituation-with-time in novel environment exploration, low anxiety and hyperactive like profile in open field test in young and adult rats. The study revealed poor forelimb neuromuscular strength in LP F1 pups till adulthood. Group occupancy plots in MWM test revealed hyperactivity with poor learning, impaired memory retention and integration, thus modeling the signs of early onset Alzehemier phenotype. In addition, a gender specific effect of LP diet with severity in males and favoring female sex was also noticed.

Abstract
Multiple biological functions of selenium manifest themselves mainly via 25 selenoproteins that have selenocysteine at their active centre. Selenium is vital for the brain and seems to participate in the pathology of disorders such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and epilepsy. Since selenium was shown to be involved in diverse functions of the central nervous system, such as motor performance, coordination, memory and cognition, a possible role of selenium and selenoproteins in brain signalling pathways may be assumed. The aim of the present review is to analyse possible relations between selenium and neurotransmission. Selenoproteins seem to be of special importance in the development and functioning of GABAergic (GABA, γ-aminobutyric acid) parvalbumin positive interneurons of the cerebral cortex and hippocampus. Dopamine pathway might be also selenium dependent as selenium shows neuroprotection in the nigrostriatal pathway and also exerts toxicity towards dopaminergic neurons under higher concentrations. Recent findings also point to acetylcholine neurotransmission involvement. The role of selenium and selenoproteins in neurotransmission might not only be limited to their antioxidant properties but also to inflammation, influencing protein phosphorylation and ion channels, alteration of calcium homeostasis and brain cholesterol metabolism. Moreover, a direct signalling function was proposed for selenoprotein P through interaction with post-synaptic apoliprotein E receptors 2 (ApoER2).

Abstract
Despite advances in care, preterm infants exhibit disproportionate growth and neurodevelopmental delay attributable to both nutritional and nonnutritional factors. These infants have prolonged linear stunting and decreased fat-free mass compared with their term counterparts. These 2 metrics index organ growth and development (including the brain) and protein accretion. Protein, along with carbohydrates, fats, and zinc, plays key roles in brain development, and deficiencies can lead to linear growth failure, abnormalities in the growth hormone axis, and developmental delay. Optimization of nutrition, including protein intake, decreasing inflammatory episodes, and enhancing the growth hormone axis will likely improve long-term outcomes.
