ISSS JOURNAL OF MICRO AND SMART SYSTEMS 2022; 11:363-382. [PMID: 35540110 PMCID: PMC9070975 DOI: 10.1007/s41683-022-00103-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 03/19/2022] [Accepted: 03/27/2022] [Indexed: 11/28/2022]
Abstract
Surface-enhanced Raman spectroscopy (SERS) is one of the most sensitive analytical tools. In some cases, it is possible to record a high-quality SERS spectrum in which even a single molecule is involved. Therefore, SERS is considered a significantly promising option as an alternative to routine analytical techniques used in food, environmental, biochemical, and medical analyzes. In this review, the definitive applications of SERS developed to identify biochemically important species (especially medical and biological) from the simplest to the most complex are briefly discussed. Moreover, the potential capability of SERS for being used as an alternative to routine methods in diagnostic and clinical cases is demonstrated. In addition, this article describes how SERS-based sensors work, addresses its advancements in the last 20 years, discusses its applications for detecting Coronavirus Disease 2019 (COVID-19), and finally describes future works. The authors hope that this article will be useful for researchers who want to enter this amazing field of research.

[PMID: 34244591 PMCID: PMC8333267 DOI: 10.1038/s12276-021-00646-3] [Citation(s) in RCA: 34] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 05/07/2021] [Accepted: 05/11/2021] [Indexed: 12/21/2022] Open
Abstract
Monoamine oxidase (MAO) is believed to mediate the degradation of monoamine neurotransmitters, including dopamine, in the brain. Between the two types of MAO, MAO-B has been believed to be involved in dopamine degradation, which supports the idea that the therapeutic efficacy of MAO-B inhibitors in Parkinson's disease can be attributed to an increase in extracellular dopamine concentration. However, this belief has been controversial. Here, by utilizing in vivo phasic and basal electrochemical monitoring of extracellular dopamine with fast-scan cyclic voltammetry and multiple-cyclic square wave voltammetry and ex vivo fluorescence imaging of dopamine with GRABDA2m, we demonstrate that MAO-A, but not MAO-B, mainly contributes to striatal dopamine degradation. In contrast, our whole-cell patch-clamp results demonstrated that MAO-B, but not MAO-A, was responsible for astrocytic GABA-mediated tonic inhibitory currents in the rat striatum. We conclude that, in contrast to the traditional belief, MAO-A and MAO-B have profoundly different roles: MAO-A regulates dopamine levels, whereas MAO-B controls tonic GABA levels.

Abstract
Dysfunction in dopaminergic neuronal systems underlie a number of neurologic and psychiatric disorders such as Parkinson's disease, drug addiction, and schizophrenia. Dopamine systems communicate via two mechanisms, a fast "phasic" release (sub-second to second) that is related to salient stimuli and a slower "tonic" release (minutes to hours) that regulates receptor tone. Alterations in tonic levels are thought to be more critically important in enabling normal motor, cognitive, and motivational functions, and dysregulation in tonic dopamine levels are associated with neuropsychiatric disorders. Therefore, development of neurochemical recording techniques that enable rapid, selective, and quantitative measurements of changes in tonic extracellular levels are essential in determining the role of dopamine in both normal and disease states. Here, we review state-of-the-art advanced analytical techniques for in vivo detection of tonic levels, with special focus on electrochemical techniques for detection in humans.

Abstract
Abnormal dopamine neurotransmission is associated with several neurological and psychiatric disorders such as Parkinson's disease, schizophrenia, attention deficiency and hyperactivity disorder, and addiction. Developing highly sensitive, selective, and fast dopamine monitoring methods is of high importance especially for the early diagnosis of these diseases. Herein, we report a new ultrasensitive electrochemical sensing platform for in situ monitoring of cell-secreted dopamine using Au-coated arrays of micropyramid structures integrated directly into a Petri dish. This approach enables the monitoring of dopamine released from cells in real-time without the need for relocating cultured cells. According to the electrochemical analyses, our dopamine sensing platform exhibits excellent analytical characteristics with a detection limit of 0.50 ± 0.08 nM, a wide linear range of 0.01-500 μM, and a sensitivity of 0.18 ± 0.01 μA/μM. The sensor also has remarkable selectivity toward DA in the presence of different potentially interfering small molecules. The developed electrochemical sensor has great potential for in vitro analysis of neuronal cells as well as early diagnosis of different neurological diseases related to abnormal levels of dopamine.

Abstract
Inborn errors of monoamine neurotransmitter biosynthesis and degradation belong to the rare inborn errors of metabolism. They are caused by monogenic variants in the genes encoding the proteins involved in (1) neurotransmitter biosynthesis (like tyrosine hydroxylase (TH) and aromatic amino acid decarboxylase (AADC)), (2) in tetrahydrobiopterin (BH4) cofactor biosynthesis (GTP cyclohydrolase 1 (GTPCH), 6-pyruvoyl-tetrahydropterin synthase (PTPS), sepiapterin reductase (SPR)) and recycling (pterin-4a-carbinolamine dehydratase (PCD), dihydropteridine reductase (DHPR)), or (3) in co-chaperones (DNAJC12). Clinically, they present early during childhood with a lack of monoamine neurotransmitters, especially dopamine and its products norepinephrine and epinephrine. Classical symptoms include autonomous dysregulations, hypotonia, movement disorders, and developmental delay. Therapy is predominantly based on supplementation of missing cofactors or neurotransmitter precursors. However, diagnosis is difficult and is predominantly based on quantitative detection of neurotransmitters, cofactors, and precursors in cerebrospinal fluid (CSF), urine, and blood. This review aims at summarizing the diverse analytical tools routinely used for diagnosis to determine quantitatively the amounts of neurotransmitters and cofactors in the different types of samples used to identify patients suffering from these rare diseases.

Abstract
In this work, the assessment of the interactions of a bioactive substance applied to immobilized cells in either a two-dimensional (2D) or three-dimensional (3D) arrangement mimicking in vivo tissue conditions is presented. In particular, dopamine (DA) was selected as a stimulant for the implementation of an impedance analysis with a specific type of neural cells (murine neuroblastoma). The aim of this study was the extraction of calibration curves at various frequencies with different known dopamine concentrations for the description of the behavior of dopamine applied to 2D and 3D cell cultures. The results present the evaluation of the mean impedance value for each immobilization technique in each frequency. The differential responses showed the importance of the impedance when frequency is applied in both 2D and 3D immobilization cases. More specifically, in 2D immobilization matrix impedance shows higher values in comparison with the 3D cell culture. Additionally, in the 3D case, the impedance decreases with increasing concentration, while in the 2D case, an opposite behavior was observed.

Abstract
A combined theoretical and experimental analysis of dopamine (DA) is presented in this work with the objective of achieving more accurate detection and monitoring of this neurotransmitter at very low concentrations, specific to physiological levels. Surface-enhanced Raman spectroscopy on silver nanoparticles was employed for recording DA concentrations as low as 10-11 molar. Quantum chemical density functional calculations were carried out using Gaussian-09 analytical suite software. Relatively good agreement between the simulated and experimentally determined results indicates the presence of different DA molecular forms, such as uncharged DA±, anionic DA-, and dopaminequinone. Disappearance of the strongest bands of dopamine around 750 cm-1 and 790 cm-1, which suggests its adsorption onto the metallic surface, is not only consistent with all of these DA configurations, but also provides additional information about the analyte's redox process and voltammetric detection. On the other hand, occurrence of the abovementioned Raman lines could indicate the formation of multilayers of DA or its presence in a cationic DA⁺ form. Thus, through coordinated experiment and theory, valuable insights into changes observed in the vibrational signatures of this important neurotransmitter can be achieved for a better understanding of its detection at physiological levels, which is crucial if further optovoltammetric medical device development is envisioned.

Abstract
A rapid, sensitive, and reproducible assay is described for the quantitative determination of the monoamine neurotransmitters dopamine, norepinephrine and serotonin, their metabolites, and the internal standard 3,4-dihydroxybenzlyamine hydro-bromide in mouse brain homogenate using high-performance liquid chromatography with electrochemical detection. The method was validated in the following brain areas: frontal cortex, striatum, nucleus accumbens, hippocampus, substantia nigra pars compacta and ventral tegmental area. Biogenic amines and relevant metabolites were extracted from discrete brain regions using a simple protein precipitation procedure, and the chromatography was achieved using a C18 column. The method was accurate over the linear range of 0.300-30 ng/mL (r = 0.999) for dopamine and 0.300-15 ng/mL (r = 0.999) for norepinephrine, 3,4-dihydroxybenzlyamine hydro-bromide, homovanillic acid and 5-hydroxyindolacetic acid, with detection limits of ~0.125 ng/mL (5 pg on column) for each of these analytes. Accuracy and linearity for serotonin were observed throughout the concentration range of 0.625-30 ng/mL (r = 0.998) with an analytical detection limit of ~0.300 ng/mL (12 pg on column). Relative recoveries for all analytes were approximately ≥90% and the analytical run time was <10 min. The described method utilized minimal sample preparation procedures and was optimized to provide the sensitivity limits required for simultaneous monoamine and metabolite analysis in small, discrete brain tissue samples.

Abstract
A simple and sensitive dopamine (DA) electrochemical sensor was fabricated based on magnetism-assisted modification of screen printed electrode (SPE) with magnetic multi-walled carbon nanotubes (mMWCNTs). The mMWCNTs modified electrodes (mMWCNTs/SPE) combines the advantages of SPE and the simultaneous contribution of magnetic nanoparticles (MNPs) and MWCNTs, increasing sensitivity and selectivity of DA detection. The linearity was found between 5μM to 180μM, with the limit of detection (LOD) of 0.43μM. In the mean time, this modified electrode exhibited excellent selectivity for DA detection with almost no interference from ascorbic acid (AA), which co-exists with DA in many bio-samples and causes common interference. Finally, this novel electrode has been applied to determine DA concentration in spiked human blood serum and satisfactory recovery was found in the range of 97.43-102.94% with the RSDs of less than 2.27%. This work developed a sensitive and reliable electrochemical analytical method based on mMWCNTs/SPE, which exhibits great potential for diagnosis of the diseases related to DA.

Abstract
Characterizing stem cell intrinsic functions is an ongoing challenge for cell therapies. Here, we report that two independent A4 and H8 stem cell lines isolated from mouse molar pulp display the overall functions of bioaminergic cells. Both clones produce neurotrophins and synthesize, catabolize, store, and transport serotonin (5-hydroxytryptamine [5-HT]) and dopamine (DA). They express 5-HT1D,2B,7 and D1,3 autoreceptors, which render pulpal stem cells competent to respond to circulating 5-HT and DA. We show that injury-activated platelets are the source of systemic 5-HT and DA necessary for dental repair since natural dentin reparation is impaired in two rat models with monoamine storage-deficient blood platelets. Moreover, selective inhibition of either D1, D3, 5-HT2B, or 5-HT7 receptor within the pulp of wild-type rat molars after lesion alters the reparative process. Altogether our data argue that 5-HT and DA coreleased by pulp injury-activated platelets are critical for stem cell-mediated dental repair through 5-HT and DA receptor signalings.

Abstract
An ultra high performance liquid chromatography-electrospray ionization-tandem mass spectrometric method (UHPLC/ESI-Q-TOF-MS) for the analysis of dopamine (DA) in Wistar rat brain homogenate has been developed and validated. The chromatographic separation was achieved on a Waters ACQUITY UPLC™ BEH C18 (100.0 mm × 2.1 mm; 1.7 µm) column using isocratic mobile phase, consisting of acetonitrile and Formic acid (0.1% w/v) (10: 90; v/v), at a flow rate of 0.15 ml min(-1) . The transitions occurred at m/z 154.04 → 137.006 for DA, and m/z 184.204 → 166.08 for the internal standard. The recovery of the analytes from Wistar rat brain homogenate was optimized using liquid-liquid extraction technique (LLE) in ethyl acetate. The total run time was 3.5 min and the elution of DA occurred at 1.44 ± 0.05 min. The linear dynamic range was established over the concentration range 75-750 ng mL(-1) (r(2) ; 0.9921 ± 0.0005) for DA. The intra-assay and inter-assay accuracy in terms of % CV was in the range 0.73-2.80. The lower limit of detection (LOD) and quantitation (LOQ) for DA was 0.278 and 0.844 ng mL(-1) , respectively. Analytes were stable under various conditions (in autosampler, during freeze-thaw, at room temperature, and under deep-freeze conditions). The developed method was successfully applied for in vivo profiling in rodents.

Abstract
A rapid and sensitive liquid chromatography tandem mass spectrometry method for simultaneous quantification of catecholamine neurotransmitters in microdialysates was developed. The catecholamine neurotransmitters dopamine (DA) and norepinephrine (NE) were pre-column derivatized with dansyl chloride and analyzed. A gradient elution method was used to separate the analytes from the interferences on an Agilent Poroshell 120 EC-C18 outer porous micro particulate column. The method was robust and sensitive to determine with the lower limit of quantification value of 0.068pmol/mL and 0.059pmol/mL for DA and NE, respectively. It has acceptable precision and accuracy for concentrations over the standard curve range. The method was successfully applied for simultaneous quantitation of DA and NE in the prefrontal cortex (PFC) dialysates of rats obtained from a microdialysis study dosed with vehicle and atomoxetine through intra peritoneal (i.p.) route at a dose of 3mg/kg to monitor the change in extracellular concentrations. Thus, accomplishment of this method would facilitate the neurochemical monitoring for discovery of new chemical entities targeted for the treatment of attention deficit hyperactivity disorder (ADHD).

Abstract
Lamotrigine is suggested to have potential as an add-on treatment for patients with schizophrenia. Supporting evidence comes from the efficacy of the drug in models of psychotic-like behaviour induced by N-methyl-D-aspartate (NMDA) receptor antagonists, such as phencyclidine (PCP). These drugs enhance levels of the monoamines in the cortex, which may contribute to their psychotomimetic effects. The ability of lamotrigine to prevent these neurochemical changes has not been examined. We studied PCP-evoked overflow of noradrenaline, dopamine and serotonin in the medial prefrontal cortex of awake rats using microdialysis. Rats were administered lamotrigine or vehicle, followed by PCP. Locomotor activity was also recorded before and after drug treatment. Lamotrigine did not have an influence on basal levels of the monoamines, but significantly reduced PCP-evoked overflow of dopamine and serotonin; PCP-evoked overflow of noradrenaline was also reduced by lamotrigine, but not to a significant degree. In contrast, PCP-induced hyperactivity was unaffected by lamotrigine. It is concluded that lamotrigine can modify PCP-evoked monoamine overflow in the cortex, consistent with an ability to prevent the psychotomimetic effects of NMDA receptor antagonists in rodents and humans. The dissociation between monoamine overflow and locomotor activity suggests the involvement of different brain circuits; relevance to the treatment of schizophrenia is also discussed.

Abstract
Neuropeptide Y (NPY) has been extensively studied in relation to anxiety and depression but of the seven NPY receptors known to date, it is not yet clear which one is mainly involved in mediating its effects in emotional behavior. Mice lacking the NPY-Y2 receptors were previously shown to be less anxious due to their improved ability to cope with stressful situations. In the present study, the behavioral phenotype including the response to challenges was analyzed in NPY-Y2 knockout (KO) mice backcrossed in to congenic C57BL/6 background. In the elevated plus-maze (EPM) and the forced swim test (FST), the anxiolytic-like or antidepressant-like phenotype of the NPY-Y2 KO mice could not be confirmed, although this study differs from the previous one only with regard to the genetic background of the mice. In addition, no differences in response to acute stress or to the antidepressant desipramine in the FST were detected between wild type (WT) and NPY-Y2 KO animals. These results suggest that the genetic background of the animals appears to have a strong influence on the behavioral phenotype of NPY-Y2 KO mice. Additionally, to further characterize the animals by their biochemical response to a challenge, the neurochemical changes induced by the anxiogenic compound yohimbine were measured in the medial prefrontal cortex (mPFC) of NPY-Y2 KO and compared to WT mice. Dopamine (DA) levels were significantly increased by yohimbine in the WT but unaffected in the KO mice, suggesting that NPY-Y2 receptor exerts a direct control over both the tonic and phasic release of DA and that, although the anxiety-like behavior of these NPY-Y2 KO mice is unaltered, there are clear modifications of DA dynamics. However, yohimbine led to a significant increase in noradrenaline (NA) concentration and a slight reduction in serotonin concentration that were identical for both phenotypes.

Abstract
The primary challenge associated with the development of an LC/MS/MS-based assay for simultaneous determination of biogenic monoamine neurotransmitters such as norepinephrine (NE), dopamine (DA), serotonin (5-HT), and normetanephrine (NM) in rat brain microdialysates is to improve detection sensitivity. In this work, a UPLC/ MS/MS-based method combined with a diethyl labeling technique was developed for simultaneous determination of a panel of monoamines in rat prefrontal cortex microdialysates. The chromatographic run time is 3.5 min/ sample. The limits of detection of the UPLC/MS/MS-based method for NE, DA, 5-HT/ and NM, with/without diethyl labeling of monoamines, are 0.005/0.4 (30/2367 pM), 0.005/0.1 (33/653 pM), 0.005/0.2 (28/1136 pM), and 0.002/0.2 ng/mL (11/1092 pM), respectively. Diethyl labeling of amino groups of monoamines affords 20-100 times increased detection sensitivity of corresponding native monoamines during the UPLC/MS/MS analysis. This could result from the following: (1) improved fragmentation patterns; (2) increased hydrophobicity and concomitantly increased ionization efficiency in ESI MS and MS/MS analysis; (3) reduced matrix interference. This labeling reaction employs a commercially available reagent, acetaldehyde-d4, to label the amine groups on the monoamines via reductive amination. It is also simple, fast (approximately 25-min reaction time), specific, and quantitative under mild reaction conditions. Data are also presented from the application of this assay to monitor the drug-induced changes of monoamine concentrations in rat prefrontal cortex microdialysate samples followed by administration of SKF 81297, a selective D1 dopamine receptor agonist known to elevate the extracellular level of the neurotransmitters DA and NE in the central nervous system.

Abstract
DFT-B3LYP/6-31G (d, p) and HF/6-31G (d, p) calculations are performed for deoxidized norepinephrineat (NP(R)) and its oxidized form (NP(O)). The electrochemistry of norepinephrineat (NP) was studied by cyclic voltammetry (CV) at a pyrolytic graphite electrode modified by Nafion multi-walled carbon nanotubes (MWNTs) in phosphate buffers at pH 6.0, showing that the standard electrode potential of half reaction for NP(O), H+/NP(R) is 0.75l V. This experimental standard electrode potential of half reaction is consistent with that calculated using the energies of solvation and sum of electronic and thermal free energies of NP(R) and NP(O). The frontier orbital theory and Mülliken charges of molecular explain the electrochemical behavior of CV at modified electrode well. The singlet vertical excited states for NP(R) and NP(O) are also discussed.

Abstract
A highly sensitive isocratic capillary high-performance liquid chromatographic (HPLC) method with electrochemical detection (ED) for the simultaneous measurement of serotonin (5-hydroxytryptamine, 5-HT) and its metabolite 5-hydroxyindole-3-acetic acid (5-HIAA) in microdialysates has been developed using a 0.5 mm i.d. capillary column and a 11-nL detection cell. This method, validated on both pharmacological and analytical bases, can be performed using injection volumes as low as 1 microL. The limits of detection were 5.6 x 10(-11)mol/L and 3.0 x 10(-9)mol/L for 5-HT and 5-HIAA. Several applications of the present method are given on microdialysates from rodent brain and human spinal cord.

Abstract
Catecholamines, for example epinephrine, norepinephrine, and dopamine, are widely distributed and are important neurotransmitters and hormones in mammalian species. Several methods have been developed for analysis of catecholamines and related compounds. Determination of catecholamines in biological fluids has enabled us to clarify the physiological role played by these amines. Catecholamine levels in plasma and/or urine are also useful for diagnosis of several diseases, for example hypertension, pheochromocytoma, and neuroblastoma. This review covers reports from 2000 to the present of methods for the analysis of catecholamines and their metabolites.

Abstract
A fast and sensitive capillary liquid chromatography (cLC) column-switching method with electrospray ionization time-of-flight mass spectrometry (ESI-TOF-MS) detection for the simultaneous determination of dopamine (D), epinephrine (E), norepinephrine (NE) and serotonin (SE) was pursued. A sample volume of 100 microl was loaded with a mobile phase containing 0.1% pentafluoropropionic acid (PFPA) as ion-pairing agent on a 25 mm x 0.32 mm (i.d.) 5 microm Hypercarb column. A water-acetonitrile (AcN) gradient with 0.1% acetic acid (AcOH) backflushed the compounds onto a 34 mm x 0.32 mm (i.d.) 5 microm Hypercarb analytical column. However, during a series of analyses, oxidation of the catecholamines (CAs) was observed. This was suspected to be due to the loading mobile phase composition and precluded the usefulness of this method even though the achievable detection limit was in the range of 0.75-3.0 ng/ml. The combination of the porous graphitic carbon (PGC) material and the fluorinated strong acids which were required to get enough retention for preconcentration of large volumes cannot be used for easily oxidized compounds as the CAs.

Abstract
Simultaneous determination of biogenic monoamines such as dopamine, serotonin, and 3-methoxytyramine in brain is important in understanding neurotransmitter activity. This study presents a sensitive determination of biogenic monoamines in rat brain striatum microdialysates using capillary high-performance liquid chromatography with the photoluminescence following electron-transfer detection technique. Separation conditions were optimized by changing the concentration of an ion-interaction agent and the percentage of an organic modifier. The high concentration of ion-interaction agent enabled the amines as a class to be separated from interfering acids, but also made the separation very long. To shorten the separation time, 10% (v/v) acetonitrile was used as the organic modifier. Eight chromatographic runs during a 3-h period were analyzed in terms of retention times, peak heights, and peak widths. Chromatograms are very reproducible, with less than 1% changes in peak height over 3 h. Typical concentration detection limits at the optimum separation conditions were less than 100 pM for metabolic acids and approximately 200 pM for monoamines. The injection volume of the sample was 500 nL. Thus, the mass detection limits were less than 50 amol for metabolic acids and approximately 100 amol for monoamines. Typical separation time was less than 10 min. To validate the technique, the separation method was applied to the observation of drug-induced changes of monoamine concentrations in rat brain microdialysis samples. Local perfusion of tetrodotoxin, a sodium channel blocker, into the striatum of an anesthetized rat decreased dopamine, 3-methoxytyramine, and serotonin concentrations in dialysates. Successive monitoring of striatal dialysates at a temporal resolution of 7.7 min showed that the injection of nomifensine transiently increased dopamine and 3-methoxytyramine concentrations in rat brain dialysate.

Abstract
During the last three decades, a great deal of information has been discovered about chemical neurotransmission. However, the most important processes, namely the complex nature of neuronal circuitry, the "cross talk" between multiple neurotransmitter systems, and the varying effects neurochemicals have at different receptors, are still being explored. Techniques such as microdialysis are routinely employed to measure neurotransmitter levels in living tissue systems. Moreover, microdialysis studies have proven to be valuable in the investigation of neurodegenerative and psychiatric disease pathology, as well as in identifying novel drugs to treat such disorders. One particular challenge in performing these experiments is the requirement to couple microdialysis to sophisticated analytical equipment. Recently, considerable attention has been focused on the development of chromatographic-mass spectrometric techniques to provide more sensitive and accurate measurements of neurochemicals collected from in vivo microdialysis experiments. This review will provide a brief overview of the microdialysis technique, as well as how microdialysis and chromatography-mass spectrometry are being used to measure extracellular levels of neurotransmitters. The primary emphasis of this review will be on how these applications are used to measure levels of acetylcholine (ACh), dopamine, norepinephrine and gamma-aminobutyric acid (GABA).

Abstract
Aripiprazole, a novel atypical antipsychotic drug, can significantly increase dopamine (DA) levels in the prefrontal cortex of rats, but only at low doses below 1mg/kg. The aim of the present work was to test the effect of aripiprazole (0, 0.1, 0.3, 3 and 30 mg/kg, i.p.) on extracellular levels of monoamines in the prefrontal cortex of freely moving C57BL/6J mice. Concurrent horizontal locomotor activity was also assessed. Aripiprazole produced a significant increase in dialysate DA levels after the administration of a low dose of 0.3mg/kg. Lower (0.1 mg/kg) or higher (3 and 30 mg/kg) doses failed to affect extracellular levels of DA. In addition, none of the doses tested in the present study produced significant changes in extracellular levels of noradrenaline (NA) and serotonin (5-HT). For the sake of comparison, clozapine (0, 3 and 10 mg/kg, s.c.) was also tested under similar conditions. Clozapine produced a dose-dependent increase in both dialysate DA and NA levels without affecting extracellular 5-HT. Locomotor activity was significantly decreased by both clozapine and aripiprazole. These data further support the hypothesis that selective activation of dopaminergic neurotransmission in the prefrontal cortex may contribute to the therapeutic efficacy of aripiprazole.

Abstract
A sensitive and selective method for simultaneous determination of carvedilol and dopamine was described. The emission wavelengths of carvedilol and dopamine were at 354 nm and 314 nm with the excitation at 290 nm, respectively. The determination of carvedilol and dopamine by normal fluorometry was difficult because the emission spectra of carvedilol and dopamine were overlapped seriously. The first derivative peaks of carvedilol and dopamine were at 336 nm and 302 nm, respectively. The linear regression equations of the calibration graphs of carvedilol and dopamine were C = 0.000557H-0.00569 and C = 0.00438H-0.0812, with the correlation coefficients were 0.9953 and 0.9988, respectively. The liner range for the determination of carvedilol was 0.002 microg ml(-1) to 0.02 microg ml(-1), and 0.05 microg ml(-1) to 0.6 microg ml(-1) for dopamine. The detection limits were 1 ng ml(-1) for carvedilol and 0.04 microg ml(-1) for dopamine, respectively. The relative standard derivative (RSD) of 4.38% and 4.35% was observed for carvedilol and dopamine, respectively. The recovery of carvedilol was from 95.00% to 106.7% in human serum and from 97.50% to 105.0% in urine sample. The recovery of dopamine was from 100.0% to 102.5% in human serum and from 97.50% to 105.0% in urine sample. This method is simple and can be used for determination of carvedilol and dopamine in human serum and urine sample with satisfactory results.

Abstract
A rapid liquid chromatography/tandem mass spectrometry (LC-MS/MS) method has been developed for the measurement of dopamine (DA), 5-hydroxytryptamine (5HT) and norepinephrine (NE) in brain microdialysates. The assay has also been utilised for the simultaneous measurement of these neurotransmitters and cocaine in brain dialysates. The neurotransmitters and cocaine were resolved in a single 4-min run using a binary gradient elution profile. The analytes were detected using tandem mass spectrometry in the positive ion electrospray mode. The limits of detection for DA, NE, 5HT and cocaine were 200, 1000, 900 pM and 1 pg ml(-1), respectively.

Abstract
In the present experiments, in vivo microdialysis techniques together with nanoprobe NMR spectroscopy were used to evaluate the neurochemical environment of the rat frontal cortex. Metabonomics techniques of data reduction and pattern recognition were used to examine whether collected neurochemicals were sensitive to tetrodotoxin (TTX), a neurotoxin that when infused into discrete brain regions can help distinguish between the neuronal versus glial origin of neurochemicals in cerebrospinal fluid microdialysate. (1)H NMR spectra recorded on samples collected from the rat frontal cortex before and after an intracortical TTX infusion (10 microM for 60 min) were subjected to multivariate statistical analysis. Glutamate, isoleucine, valine, alanine, and alpha- and beta-hydroxybutyrate were found to have decreased concentrations after the addition of TTX, suggesting that their release is likely from cortical neurons. In contrast, lactate, formate, acetate, glucose, creatinine, pyruvate, and other neurochemicals remained unchanged following local application of TTX. The present findings extend our previous work combining the analytical technology of small-volume nanoprobe NMR spectroscopy with in vivo microdialysis in freely moving animals and show that it is possible to apply metabonomics methodology to this important class of biofluid to monitor changes in neurochemical composition of the rat brain.

Abstract
An assay was developed to quantify norepinephrine (NE) and its metabolites (MHPG and DHPG) by high-performance liquid chromatography with electrochemical detection method (HPLC-ECD) in brain tissue and plasma of rats treated by LiCl. Separation on C(18) column was obtained by a mobile phase consisting of 4.5% methanol in buffer (0.1 M sodium acetate, 0.2 M citric acid) containing 0.2 mM ethylenediaminetetraacetic acid disodium salt (EDTA Na(2)) and 0.4 mM sodium octylsulfate, operated at a flow rate of 0.8 ml/min. A potential of +0.78 V was applied across the working and reference electrodes of the detector. The precision was in the range 2.88-4.35% for NE, 5.94-11.0% for MHPG and 1.97-4.40% for DHPG. Accuracy was 98.8-99.3% for NE, 97.4-100% for MHPG and 96.1-101% for DHPG. The limit of detection was 0.6 ng/ml for NE, 0.5 ng/ml for MHPG and 0.2 ng/ml for DHPG. The linearity is over the range 20-60 ng/ml for NE, 7-23 ng/ml for MHPG and 6-20 ng/ml for DHPG. The assay has been applied successfully to measure simultaneously cortex and plasmas concentrations of these three catecholamines in rats.

Abstract
Nuclear magnetic resonance (NMR) spectroscopy was used to study the chemical composition of cerebrospinal fluid (CSF) microdialysate from the rat brain. In vivo microdialysis techniques were used in several brain regions including the frontal cortex, amygdala, striatum, nucleus accumbens and third ventricle and dialysate samples (20microl) were subsequently analyzed by one and two-dimensional 1H NMR experiments using a Varian nanoprobe. Neurochemical resonances were assigned on the basis of published chemical shifts [Lindon et al., Ann. Rep. NMR Spectrosc. 38 (1999) 1-88], correlation experiments and addition of standard compounds. Glucose, lactate, formate, pyruvate, creatinine, gamma-hydroxybutyrate, acetate, glutamate, glycine, tyrosine, isoleucine, leucine, alanine and choline were some of the neurochemicals unambiguously assigned. Additional studies in the frontal cortex showed that amino acids such as glutamate, alanine and isoleucine were sensitive to local tetrodotoxin (TTX) infusion. The NMR spectra were also subjected to multivariate statistical methods to compare the different brain regions examined. To our knowledge, the present experiments are the first to describe the combination of nanoprobe NMR technology with in vivo microdialysis for the analysis of brain neurochemistry in freely-moving rats.

Abstract
Both push-pull and microdialysis methods are utilized to measure norepinephrine and serotonin in the dorsal horn of the spinal cord. This experiment was designed to determine which technique is better for measurement of norepinephrine and serotonin in the spinal cord and also to determine if the samples are best collected with or without perchloric acid. Sample stability and an assay validation for precision, limit of quantification, and limit of detection were also performed. Push-pull or microdialysis catheters were placed transversely through the dorsal horn and the catheter was perfused with artificial cerebrospinal fluid. Noxious pinch (20 s/min for 10 min) was used to evoke a change in the concentration of catecholamines. Samples were collected before, during and after pinch. No basal concentrations of epinephrine and serotonin were found with microdialysis. Although basal concentrations of norepinephrine were measured by microdialysis, there was no change in response to noxious pinch. The push-pull technique coupled with collection of samples without perchloric acid showed that significant increases in serotonin and norepinephrine are measurable in response to noxious pinch. In contrast, when samples were collected with perchloric acid present there was no change in serotonin or norepinephrine in response to pinch. The stability of catecholamines is greatly affected by perchloric acid such that there is a near complete loss of ability to detect serotonin and norepinephrine by 24 h in samples collected by push-pull. In contrast, samples collected without perchloric acid showed only a 20% reduction in concentration by 24 h. Even without perchloric acid, by 1 wk there was a 50% or greater loss in the concentrations of norepinephrine in push-pull samples. Thus, to measure changes in catecholamines in the dorsal horn, push-pull collected without perchloric provides measurable, reliable and valid results if analyzed by high performance liquid chromatography within 24 h.

Abstract
Recent neuroanatomical and functional investigations focusing on dopamine (DA) D(3) receptors have suggested a potential role of this receptor in psychiatric diseases such as schizophrenia and drug dependence. In line with the key role of the prefrontal cortex in psychiatric disorders, the present study aimed at assessing the effects of the acute systemic administration of the selective DA D(3) receptor antagonist SB-277011-A on the in vivo extracellular levels of monoamines (DA, norepinephrine (NE), and serotonin (5-HT)) and acetylcholine (ACh) in the anterior cingulate subregion of the medial prefrontal cortex. The in vivo neurochemical profile of SB-277011-A (10 mg/kg, i.p.) in the anterior cingulate cortex was compared with both typical and atypical antipsychotics including clozapine (10 mg/kg, s.c.), olanzapine (10 mg/kg, s.c.), sulpiride (10 mg/kg, s.c.), and haloperidol (0.5 mg/kg, s.c.). The acute administration of SB-277011-A, clozapine, and olanzapine produced a significant increase in extracellular levels of DA, NE, and ACh without affecting levels of 5-HT. Sulpiride also significantly increased extracellular DA, but with a delayed onset over SB-277011-A, clozapine, and olanzapine. In contrast, haloperidol failed to alter any of the three monoamines and ACh in the anterior cingulate cortex. These findings add to a growing body of evidence suggesting a differentiation between typical and atypical antipsychotic drugs (APDs) in the anterior cingulate cortex and a role of DA D(3) receptors in desired antipsychotic drug profile. Similar to their effects on DA and NE, SB-277011-A, clozapine, and olanzapine increased extracellular levels of ACh, whereas haloperidol and sulpiride did not alter ACh. The results obtained in the present study provide evidence of the important role of DA D(3) receptors in the effect of pharmacotherapeutic agents that are used for the treatment of psychiatric disorders such as schizophrenia and drug dependence.

Abstract
Dual probe microdialysis was employed to characterize the origins of dialysate glutamate, aspartate and gamma-aminobutyric acid (GABA) in the medial prefrontal cortex (mPfc) and to investigate functional interactions between the mPfc and ventral tegmental area (VTA) in awake, freely moving rats. Perfusion with elevated potassium (K(+); KCl, 100 mM, 20 min), low Ca(2+) (0.1 mM, 60 min) or tetrodotoxin (TTX, 10 microM, 100 min) was performed in the mPfc and dialysate levels of glutamate, aspartate and GABA were measured locally and in the VTA. Elevated K(+) in the mPfc rapidly increased dialysate glutamate and aspartate locally (+90+/-10 and +41+/-9% from basal, respectively) and in the VTA (+71+/-14 and +42+/-14%, respectively). MPfc GABA was also rapidly increased (+241+/-62%) while VTA GABA was not affected. Perfusion with low Ca(2+) in the mPfc decreased local glutamate, aspartate and GABA (-26+/-8; -35+/-7 and -45+/-8%, respectively) and decreased only GABA (-40+/-5%) in the VTA. Intra-mPfc TTX increased glutamate and aspartate locally (+82+/-23 and +54+/-27%, respectively) and in the VTA (+84+/-18 and +38+/-17%, respectively). In contrast, intra-mPfc TTX decreased local GABA (-33+6%) while VTA GABA levels were not affected. Taken together, these data confirm the influence of the mPfc upon the ipsilateral VTA and provide evidence for two neuronal pools which contribute to basal extracellular mPfc and VTA glutamate, aspartate and GABA levels, the first pool derived from Na(+)- and Ca(2+)-dependent release and the second derived from voltage-dependent reuptake.
