Abstract
The first trimester of pregnancy ranks high in priority when minimizing harmful exposures, given the wide-ranging types of organogenesis occurring between 4- and 12-weeks' gestation. One way to quantify potential harm to the fetus in the first trimester is to measure a corollary effect on the placenta. Placental biomarkers are widely present in maternal circulation, cord blood, and placental tissue biopsied at birth or at the time of pregnancy termination. Here we evaluate ten diverse pathways involving molecules expressed in the first trimester human placenta based on their relevance to normal fetal development and to the hypothesis of placental-fetal endocrine disruption (perturbation in development that results in abnormal endocrine function in the offspring), namely: human chorionic gonadotropin (hCG), thyroid hormone regulation, peroxisome proliferator activated receptor protein gamma (PPARγ), leptin, transforming growth factor beta, epiregulin, growth differentiation factor 15, small nucleolar RNAs, serotonin, and vitamin D. Some of these are well-established as biomarkers of placental-fetal endocrine disruption, while others are not well studied and were selected based on discovery analyses of the placental transcriptome. A literature search on these biomarkers summarizes evidence of placenta-specific production and regulation of each biomarker, and their role in fetal reproductive tract, brain, and other specific domains of fetal development. In this review, we extend the theory of fetal programming to placental-fetal programming.

Abstract
Diabetes mellitus is an increasing metabolic disease worldwide associated with central nervous system disorders. Coffee is a widely consumed beverage that enriched with antioxidants with numerous medicinal applications. Accordingly, the present study aimed to investigate the therapeutic potential of orally administered green coffee bean water extract (GCBWE) against cortical damage induced by high fat diet (HFD) followed by a single injection of streptozotocin (STZ) in rats. Metformin (Met) was used as standard antidiabetic drug. Animals were allocated into six groups: control, GCBWE (100 mg/kg), HFD/STZ (40 mg/kg), HFD/STZ + GCBWE (50 mg/kg), HFD/STZ + GCBWE (100 mg/kg) and HFD/STZ + Met (200 mg/kg) which were treated daily for 28 days. Compared to control rats, HFD/STZ-treated rats showed decreased levels of cortical dopamine, norepinephrine and serotonin with marked increases in their metabolites. Further, HFD/STZ treatment resulted in notable elevations in malondialdehyde, protein carbonyl and total nitrite levels paralleled with declines in antioxidant markers (SOD, CAT, GPx, GR and GSH) and down-regulations of Sod2, Cat, GPx1 and Gsr gene expression. Neuroinflammation was evident in diabetic animals by marked elevations in TNF-α, IL-1β and up-regulation of inducible nitric oxide synthase. Significant rises incaspase-3 and Bax with decline in Bcl-2 level were noticed in diabetic rats together with similar results in their gene expressions. Cortical histopathological examination supported the biochemical and molecular findings. GCBWE administration achieved noteworthy neuroprotection in diabetic animals in most assessed parameters. The overall results suggested that antioxidant, anti-inflammatory; anti-apoptotic activities of GCBWE restored the cortical neurochemistry in diabetic rats.

Abstract
Early malnutrition is a risk factor for depression and schizophrenia. Since the offspring of malnourished dams exhibit increased brain levels of serotonin (5-HT), a tryptophan-derived neurotransmitter involved in the pathophysiology of these mental disorders, it is believed that the deleterious effects of early malnutrition on brain function are due in large part to altered serotoninergic neurotransmission resulting from impaired tryptophan (Trp) metabolism. However, tryptophan is also metabolized through the kynurenine (KYN) pathway yielding several neuroactive compounds including kynurenic (KA), quinolinic (QA) and xanthurenic (XA) acids. Nevertheless, the impact of perinatal malnutrition on brain kynurenine pathway metabolism has not been examined to date. Here, we used ultra-performance liquid chromatography-tandem mass spectrometry for the simultaneous quantification of tryptophan and a set of seven compounds spanning its metabolism through the serotonin and kynurenine pathways, in the brain of embryos and adult offspring of rat dams fed a protein-restricted (PR) diet. Protein-restricted embryos showed reduced brain levels of Trp, serotonin and KA, but not of KYN, XA, or QA. In contrast, PR adult rats exhibited enhanced levels of Trp in the brainstem and cortex along with increased concentrations of 5-HT, kynurenine and XA. The levels of XA and KA were also increased in the hippocampus of adult PR rats. These results show that early protein deficiency induces selective and long-lasting changes in brain kynurenine metabolism. Given the regulatory role of KYN pathway metabolites on brain development and function, these changes might contribute to the risk of developing psychiatric disorders induced by early malnutrition.

Abstract
Although obesity is a global epidemic, the physiological mechanisms involved are not well understood. Recent advances reveal that susceptibility to obesity can be programmed by maternal and neonatal nutrition. Specifically, a maternal low-protein diet during pregnancy causes decreased intrauterine growth, rapid postnatal catch-up growth and an increased risk for diet-induced obesity. Given that the synthesis of the neurotransmitter 5-hydroxytryptamine (5-HT) is nutritionally regulated and 5-HT is a trophic factor, we hypothesised that maternal diet influences fetal 5-HT exposure, which then influences development of the central appetite network and the subsequent efficacy of 5-HT to control energy balance in later life. Consistent with our hypothesis, pregnant rats fed a low-protein diet exhibited elevated serum levels of 5-HT, which was also evident in the placenta and fetal brains at embryonic day 16.5. This increase was associated with reduced levels of 5-HT2CR, the primary 5-HT receptor influencing appetite, in the fetal, neonatal and adult hypothalamus. As expected, a reduction of 5-HT2CR was associated with impaired sensitivity to 5-HT-mediated appetite suppression in adulthood. 5-HT primarily achieves effects on appetite by 5-HT2CR stimulation of pro-opiomelanocortin (POMC) peptides within the arcuate nucleus of the hypothalamus (ARC). We show that 5-HT2ARs are also anatomically positioned to influence the activity of ARC POMC neurons and that mRNA encoding 5-HT2AR is increased in the hypothalamus ofin uterogrowth-restricted offspring that underwent rapid postnatal catch-up growth. Furthermore, these animals at 3 months of age are more sensitive to appetite suppression induced by 5-HT2AR agonists. These findings not only reveal a 5-HT-mediated mechanism underlying the programming of susceptibility to obesity, but also provide a promising means to correct it, by treatment with a 5-HT2AR agonist.

Abstract
The incidence of diabetes is increasing worldwide. Chronic neuropathic pain occurs in approximately 25% of diabetic patients. Tramadol, an atypical analgesic with a unique dual mechanism of action, is used in the management of painful diabetic neuropathy. It acts on monoamine transporters to inhibit the reuptake of norepinephrine (NE), serotonin (5-HT), and dopamine (DA). The purpose of this study was to evaluate the effects of diabetes on the brain neurotransmitter alterations induced by tramadol in rats, and to study the hepatic and renal toxicities of the drug. Eighty Sprague-Dawley rats were divided randomly into two sets: the normal set and the diabetic set. Diabetes was induced in rats. Tramadol was administered orally once daily for 28 days. The levels of DA, NE, and 5-HT in cerebral cortex, thalamus/hypothalamus, midbrain, and brainstem were evaluated in rats. In addition, the renal toxicity and histopathological effects of the drug were assessed. The induction of diabetes altered neurotransmitter levels. Oral administration of tramadol significantly decreased the neurotransmitter levels. Diabetes significantly altered the effects of tramadol in all brain regions. Tramadol affected function and histology of the liver and kidney. The clinical effects of tramadol in diabetic patients should be stressed.

Abstract
It is known that L-tryptophan stimulates serotonin synthesis in the brain and serotonergic neuronal activity. Also, the N1/P2 component of auditory evoked potential (AEP) is a good indicator of this activity in the auditory cortex. In the present work, we examined the effect of the L-tryptophan administration on electric activity of the auditory cortex recorded as the N1/P2 component of the AEP in adult male rats. The effect of serotonergic agonists or antagonists was also tested. The results showed that indeed L-tryptophan was able to induce a drastic change in auditory cortex electric activity, reducing very significantly the amplitude of the N1/P2 component of the AEP. Quipazine maleate had a similar effect as L-tryptophan and the serotonergic antagonist spiperone induced an increase in the N1/P2 amplitude. These results show how an isolated nutrient is able to induce significant changes in brain auditory cortical function, through stimulation of serotonin synthesis. Besides, they add evidence about the important role of serotonergic neurotransmission modulating sensory cortical activity and that the N1/P2 component of AEPs represent a useful noninvasive indicator of brain serotonin tone.

Abstract
Background & Aims Maternal undernutrition programs metabolic adaptations which are ultimately detrimental to adult. L-tryptophan supplementation was given to manipulate the long-term sequelae of early-life programming by undernutrition and explore whether cultured cells retain circadian clock dysregulation. Methods Male rat pups from mothers fed on low protein (8%, LP) or control (18%, CP) diet were given, one hour before light off, an oral bolus of L-tryptophan (125 mg/kg) between Day-12 and Day-21 of age. Body weight, food intake, blood glucose along with the capacity of colonization of primary cells from biopsies were measured during the young (45–55 days) and adult (110–130 days) phases. Circadian clock oscillations were re-induced by a serum shock over 30 hours on near-confluent cell monolayers to follow PERIOD1 and CLOCK proteins by Fluorescent Linked ImmunoSorbent Assay (FLISA) and period1 and bmal1 mRNA by RT-PCR. Cell survival in amino acid-free conditions were used to measure circadian expression of MAP-LC3B, MAP-LC3B-FP and Survivin. Results Tryptophan supplementation did not alter body weight gain nor feeding pattern. By three-way ANOVA of blood glucose, sampling time was found significant during all phases. A significant interaction between daily bolus (Tryptophan, saline) and diets (LP, CP) were found during young (p = 0.0291) and adult (p = 0.0285) phases. In adult phase, the capacity of colonization at seeding of primary cells was twice lower for LP rats. By three-way ANOVA of PERIOD1 perinuclear/nuclear immunoreactivity during young phase, we found a significant effect of diets (p = 0.049), daily bolus (p<0.0001) and synchronizer hours (p = 0.0002). All factors were significantly interacting (p = 0.0148). MAP-LC3B, MAP-LC3B-FP and Survivin were altered according to diets in young phase. Conclusions Sequelae of early-life undernutrition and the effects of L-tryptophan supplementation can be monitored non-invasively by circadian sampling of blood D-glucose and on the expression of PERIOD1 protein in established primary cell lines.

Abstract
The aim of this study was to determine whether intrauterine growth restriction produces an increase of dihydropteridine reductase activity as a compensatory mechanism that maintains the necessary concentration of cofactor, tetrahydrobiopterin, during accelerated brain serotonin biosynthesis. Intrauterine growth-restricted offspring and controls were used. On days 1, 10, 15 and 21 of life, the brainstem was dissected and l-tryptophan, serotonin, tryptophan-5-hydroxylase and dihydropteridine reductase activities were determined. Intrauterine growth-restricted pups showed a significant increase of l-tryptophan, 5-hydroxytryptamine, tryptophan-5-hydroxylase and also dihydropteridine activity in the brainstem in comparison to normal pups. These results confirm that intrauterine growth restriction produces an increase of serotonin biosynthesis in the brainstem. This is accompanied by an increase in dihydropteridine activity that appears to be a compensatory mechanism to maintain sufficient tetrahydrobiopterin for the donation of electrons during the accelerated synthesis of brain serotonin in intrauterine growth-restricted rats.

Different types of nutritional deficiencies affect different domains of spatial memory function checked in a radial arm maze. Neuroscience 2008; 152:859-66.

Abstract
Several studies using animal models have suggested that the effects of nutritional insult on the developing brain are long-lasting and lead to permanent deficits in learning and behavior. Malnutrition can refer to the availability of all the nutrients but in insufficient quantities or it may imply that one or more of essential nutrients is either missing or is present, but in the wrong proportions in the diet. The hypothesis addressed in this study is that different domains of cognitive functioning can be affected by malnutrition and this can be related to the type of nutritional deficiency that the brain has been exposed to during development. To study the effect of nutritional deprivation during brain development, a paradigm of maternal malnutrition during the period of gestation and lactation was used and its effects were studied on the F1 offspring using Swiss albino mice. Three different types of malnutrition were used, that involve, caloric restriction, inadequate amount of protein in the diet and condition of low iron content. Our results show that the domain of spatial memory affected in the F1 generation depended on the kind of malnutrition that the mother was subjected to. Further our study shows that although hippocampal volume was reduced in all F1 pups, hippocampal subregions of the F1 animals were differentially vulnerable depending on type of malnutrition that the mother was subjected to. These results highlight the importance of qualifying the kind of malnutrition that is suffered by the mother during the period of gestation and lactation as it has consequences for the cognitive domain affected in the offspring. Awareness of this should inform prevention strategies in trying to reverse the effects of adverse maternal nutrition during critical periods in brain development.

Abstract
OBJECTIVE To evaluate whether the free fraction of L-tryptophan (L-Trp) and the N1/P2 component of the auditory evoked potentials (AEPs) are associated with impaired brain serotonin neurotransmission in infants with intrauterine growth restriction (IUGR). STUDY DESIGN We measured free, bound, and total plasma L-Trp and recorded the N1/P2 component of AEP in a prospective, longitudinal, and comparative study comparing IUGR and control infants. RESULTS Plasma free L-Trp was increased and the amplitude of N1/P2 component was significantly decreased in IUGR relative to control infants. The free fraction of L-Trp and N1/P2 component had a negative association. CONCLUSIONS In newborns with IUGR, the changes in measured plasma free fraction of L-Trp and in the amplitude the N1/P2 component of the AEP suggest an inverse association between free L-Trp and components of the AEP. The changes observed in the free fraction of L-Trp and AEP may be causally associated with brain serotonergic activity in utero. In IUGR, epigenetic factors such as stress-induced disturbances in brain serotonin metabolism or serotonergic activity, identifiable by alterations in AEP, influence cerebral sensory cortex development and may be causally associated with serotonin-related disorders in adulthood.

Abstract
In this study, we report that 5-HT(1A) receptors are already present in fractions of axonal growth cones, from the normal rat fetal brain (E-17). Also, in utero undernourished (UN) rat pups at birth show a noteworthy enhancement in the B(max) of [3H]5-hydroxytryptamine (5-HT) and [3H]8-hydroxy-(2-N,N-dipropilamin)-tetralin (([3H])8-OH-DPAT), in the brainstem and cerebral cortex up to the second week after birth. Afterwards, there is a significant decrease in the binding of these ligands. [125I]Cyanopindolo binding in the cerebral cortex only showed a decrease in the same period. An elevation of brain serotonin in both regions was also present. These findings together, suggest that the mechanisms of regulation of serotonergic receptors' expression during the period studied, may not depend on the amount of neurotransmitter in the synaptic cleft, because in the early UN brain it would be expected only a lower receptor's density due to the chronic serotonin increase. On this basis, we propose that developmental activation of brain serotonin biosynthesis observed in early UN animals may disrupt the mechanism regulating the expression of 5-HT receptors during development.

Abstract
In the course of the present research in school children with insulin-dependent diabetes mellitus, we observed that the free fraction of L-tryptophan, the free fraction of L-tryptophan/total L-tryptophan, and the free fraction of L-tryptophan/neutral amino acids ratios, are significantly reduced. The decrease of free fraction of L-tryptophan in plasma with a concomitant decrease of the free fraction of L-tryptophan/neutral amino acids ratio suggest a decrease in the transport of the precursor amino acid to the brain and in the serotonin synthesis rate, similar to that observed in diabetic animals. This finding may be of relevance in the pathophysiology and in the clinical picture, which could be related to an alteration of serotonin metabolism and neurotransmission in the brain and may be possibly related to neuropsychiatric disorders in diabetic school children. Thus we propose that the free fraction of L-tryptophan and the free fraction of L-tryptophan/neutral amino acids ratios may be clinically useful as indicators of brain serotonergic activity in these patients. In our laboratory, we are currently obtaining additional data on the functional role of the brain serotonergic system in humans to further support the relevance of our results.

Abstract
Previous data derived from anesthetized, decerebrate, or in vitro preparations suggested that 5-HT(2) receptor activation might be responsible for respiratory dysfunction. Such a mechanism has not yet been documented in the intact animal, but might be of clinical relevance to the apneic spells of the premature infant. In the present investigation on conscious newborn rats we analyzed the respiratory response to the activation of 5-HT(2A/2C) receptors by the agonist 1-(2.5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI), and we delineated central structures possibly involved in this response, using Fos expression as a marker of neuronal activation. We demonstrated that intraperitoneal injection of 5 mg/kg DOI produced a long-lasting decrease in respiratory frequency and tidal volume, which could be blocked by the antagonist ritanserin. Fos immunohistochemistry suggested that the rostral ventrolateral medulla and the lateral paragigantocellular nucleus might have a key role in the respiratory response to 5-HT(2) receptor activation. In addition, double immunostaining for Fos and tyrosine hydroxylase suggested that the contribution of catecholaminergic neurons to this response might be modest and indirect.

Abstract
In utero undernourishment produces an elevation of L-tryptophan and serotonin in the brain, including the auditory cortex (A1), such changes seem to be related to an increase in the free fraction (FFT) of plasma L-tryptophan that is transported into the brain through the blood-brain barrier, where it is taken up by serotonergic neurons for serotonin synthesis. Our observations support that FFT has a positive correlation with L-tryptophan (L-Trp) and serotonin levels in the auditory cortex (r=0.95 and 0.82, respectively). Interestingly, a decreased intensity dependence of the auditory evoked N1/P2 component was found in gestationally undernourished animals during their postnatal development. The N1/P2 component had a negative correlation (r=0.81) with A1 serotonin, such that it reflects changes in the neurotransmitter concentration. The present observations suggest a relevant role of serotonin in modulating the activity of the auditory cortex. Since the N1/P2 component is mainly associated with the activity of A1 neurons, it may well be that perception of auditory information is impaired during this developmental period, in the early undernourished animals, possibly affecting cognitive processes. This may be relevant to humans since low birth weight babies that also suffered gestational undernourishment (fetal-placental insufficiency) present an increase in plasma FFT from birth up to 3 months of age. These findings support that the plasma FFT and the intensity dependence of the auditory evoked N1/P2 component relate one another and may be markers of changes of the brain serotonergic activity.
