Protti M, Gualandi I, Zappoli S, Mandrioli R, Mercolini L, Tonelli D. Evaluation of the Antioxidant Capacity of Fruit Juices by Two Original Analytical Methods. Molecules 2023; 28:6672. [PMID: 37764448 PMCID: PMC10535534 DOI: 10.3390/molecules28186672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Revised: 09/15/2023] [Accepted: 09/16/2023] [Indexed: 09/29/2023] Open
Abstract
Two analytical methods previously developed by our groups were employed to estimate the antioxidant capacity of commercial fruit juices. The electrochemical method, which measures the scavenging activity of antioxidants towards OH radicals generated by both hydrogen peroxide photolysis and Fenton's reaction, is based on the recovery of the cyclic voltametric response of the redox probe Ru(NH3)63+ at a Glassy Carbon electrode modified with a thin film of an insulating polyphenol, in the presence of compounds with antioxidant properties. The values of the antioxidant capacity of the fruit juices are expressed as vitamin C equivalents/L. The chromatographic method is based on the generation of OH radicals via Fenton's reaction in order to test the inhibition of their formation in the presence of antioxidant compounds by monitoring salicylate aromatic hydroxylation derivatives as markers of •OH production, by means of HPLC coupled to coulometric detection. The results are expressed as the percentage of inhibition of •OH production in the presence of the tested juice compared to the control sample. When OH radicals are produced by Fenton's reaction, the antioxidant capacity of the juices, estimated by both methods, displays an analogous trend, confirming that they can be considered an alternative for measuring the ability of antioxidants to block OH radical formation.

Abstract
Dopamine (DA) and l-tyrosine (l-Tyr) are neurotransmitters involved in various neuropsychiatric disorders. Therefore, it is important to monitor their levels for diagnosis and treatment. In this study, we synthesized poly (methacrylic acid)/graphene oxide aerogels (p(MAA)/GOA) by in situ polymerization and freeze-drying using graphene oxide and methacrylic acid as substrates. Then, the p(MAA)/GOA were applied as solid-phase extraction adsorbents to extract DA and l-Tyr from urine samples, followed by quantification using high performance liquid chromatography (HPLC). The p(MAA)/GOA showed better adsorption performance for DA and l-Tyr than commercial adsorbents, likely as a result of the strong adsorption of the target analytes via π-π and hydrogen bonding interactions. Further, the developed method had good linearity (r > 0.9990) at concentrations of DA and l-Tyr of 0.075-2.0 and 0.75-20.0 μg mL-1, respectively, as well as a limit of detection of 0.018-0.048 μg mL-1, limit of quantitation of 0.059-0.161 μg mL-1, spiked recovery of 91.1-104.0%, and interday precision of 3.58-7.30%.The method was successfully applied to determine DA and l-Tyr in the urine samples of patients suffering from depression, demonstrating its potential for clinical applications.

Front Neurosci 2023; 17:1136499. [PMID: 36908789 PMCID: PMC9995904 DOI: 10.3389/fnins.2023.1136499] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 02/10/2023] [Indexed: 02/25/2023] Open
Abstract
Objective Evidence shows that the impairment of executive function (EF) is mainly attributed to the degeneration of frontal-striatal dopamine pathway. Glial cell line-derived neurotrophic factor (GDNF), as the strongest protective neurotrophic factor for dopaminergic neurons (DANs), may play a role in EF to some extent. This study mainly explored the correlation between serum GDNF concentration and EF performance in Parkinson's disease (PD). Methods This study recruited 45 healthy volunteers (health control, HC) and 105 PD patients, including 44 with mild cognitive impairment (PD-MCI), 20 with dementia (PD-D), and 20 with normal cognitive function (PD-N). Neuropsychological tests were performed to evaluate EF (working memory, inhibitory control, and cognitive flexibility), attention, language, memory, and visuospatial function. All subjects were tested for serum GDNF and homovanillic acid (HVA) levels by ELISA and LC-ESI-MS/MS, respectively. Results PD-MCI patients showed impairments in the trail making test (TMT) A (TMT-A), TMT-B, clock drawing test (CDT) and semantic fluency test (SFT), whereas PD-D patients performed worse in most EF tests. With the deterioration of cognitive function, the concentration of serum GDNF and HVA in PD patients decreased. In the PD group, the serum GDNF and HVA levels were negatively correlated with TMT-A (r GDNF = -0.304, P < 0.01; r HVA = -0.334, P < 0.01) and TMT-B (r GDNF = -0.329, P < 0.01; r HVA = -0.323, P < 0.01) scores. Serum GDNF levels were positively correlated with auditory verbal learning test (AVLT-H) (r = 0.252, P < 0.05) and SFT (r = 0.275, P < 0.05) scores. Serum HVA levels showed a positively correlation with digit span test (DST) (r = 0.277, P < 0.01) scores. Stepwise linear regression analysis suggested that serum GDNF and HVA concentrations and UPDRS-III were the influence factors of TMT-A and TMT-B performances in PD patients. Conclusion The decrease of serum GDNF concentration in PD patients was associated with impaired inhibitory control, cognitive flexibility, and attention performances. The changes of GDNF and HVA might synergistically participate in the occurrence and development of executive dysfunction in PD patients.

Abstract
OBJECTIVES Mild cognitive impairment is a common non-motor feature of Parkinson's disease, termed PD-MCI. But there is a scarcity of data on the role of glial cell line-derived neurotrophic factor (GDNF) and neurotransmitters in pathogenesis of PD-MCI. The aim of this project was to detect the serum levels of GDNF and multiple neurotranmitters and explore their relationships with cognitive performance in PD-MCI patients. METHODS Neuropsychological testing was administered to PD patients and healthy controls to investigate different domains of cognitive function. Serum levels of GDNF and four cognition-related neurotransmitters including Dopamine metabolites Homovanillic acid (HVA), acetylcholine (Ach), γ-aminobutyric acid (GABA) and 5-hydroxytryptamine (5-HT) were detected by enzyme-linked immunosorbent assay and liquid chromatography-electrospray ionization tandem mass spectrometry analysis respectively. RESULTS The more serious cognitive impairment of PD, the lower levels of GDNF, HVA and 5-HT. In PD-MCI patients, the levels of GDNF, HVA, Ach, 5-HT, and GABA had a significant positive correlation with Digit span backward test (DSB-T) scores and negative correlation with the scores of Trail Making Test A (TMT-A) and Trail Making Test B (TMT-B) respectively. Effect size analysis showed that GDNF and GDNF*Ach have a significant effect on DSB-T, TMT-A and TMT-B respectively; GDNF*HVA, GDNF*5-HT and GDNF*GABA play important part in Auditory Verbal Learning Test separately. CONCLUSIONS Serum GDNF may be involved in the impairment of attention, memory and executive function of PD-MCI patients, by acting alone or in conjunction with neurotransmitters (HVA, 5-HT, GABA, and Ach).

Abstract
Hydroxyl radicals (•OH) can be generated via Fenton chemistry catalyzed by transition metals. An in vitro Fenton system was developed to test both the inhibition and stimulation of •OH formation, by monitoring salicylate aromatic hydroxylation derivatives as markers of •OH production. The reaction was optimized with either iron or copper, and target analytes were determined by means of an original HPLC method coupled to coulometric detection. The method granted good sensitivity and precision, while method applicability was tested on antioxidant compounds with and without chelating properties in different substance to metal ratios. This analytical approach shows how Fenton's reaction can be monitored by HPLC coupled to coulometric detection, as a powerful tool for studying molecules' redox behavior.

Abstract
Neurotransmitters play a major role in shaping everyday life and functions. Accurate analytical methods are needed for detection of neurotransmitters. Packed-fiber solid-phase extraction (PFSPE) has been developed and seems to be an efficient method. This novel method is based on use of an electrospun polymer device, based on nanofibers. This strategy will be helpful for the development of real-time methods and techniques with high sensitivity to detect target neurotransmitters with high efficiency. Here we provide a brief overview of PFSPE and its applications for the determination of neuro-active molecules.

Abstract
We have developed a solid-phase extraction method based on conductive polypyrrole (PPy) hollow fibers which were fabricated by electrospinning and in situ polymerization. The electrospun poly (e-caprolactone) (PCL) fibers were employed as templates for the in situ surface polymerization of PPy under mechanical stirring or ultrasonication to obtain burr-shaped or smooth fiber shells, respectively. Hollow PPy fibers, achieved by removing the PCL templates, were the ideal sorbents for solid phase extraction of polar compounds due to their inherent multi-functionalities. By using the hollow PPy fibers, two important neuroendocrine markers of behavioural disorders, 5-hydroxyindole-3-acetic acid and homovanillic acid, were successfully extracted. Under the optimized conditions, the absolute recoveries of the above two neuroendocrine markers were 90.7% and 92.4%, respectively, in human plasma. Due to its simplicity, selectivity and sensitivity, the method may be applied to quantitatively analyse the concentrations of polar species in complex matrix samples.

Abstract
UNLABELLED Childhood neglect and poor child-parent relationships have been reported to increase substance use disorders susceptibility. Stressful environmental factors, including emotional neglect, could affect individual personality traits and mental health, possibly inducing stable changes in hypothalamic-pituitary-adrenal (HPA) axis and brain mono-amine function, in turn involved in addictive behavior vulnerability. Therefore, we decided to investigate homovanillic (HVA) and prolactin (PRL) plasma levels, as expression of possible changes in dopamine function, ACTH and cortisol plasma levels, as measures of HPA axis function, and concomitant psychiatric symptoms profile in abstinent cocaine addicts, in relationship to their childhood history of neglect and poor parental care perception. METHODS Fifty abstinent cocaine dependent patients, and 44 normal controls, matched for age and sex, were submitted to a detailed psychiatric assessment (DSM IV criteria). All patients and controls completed the Symptoms Check List-90 (SCL-90) and the Buss Durkee Hostility Inventory (BDHI), to evaluate psychiatric symptoms frequency and aggressiveness levels. The Childhood Experience of Care and Abuse-Questionnaire (CECA-Q) and Parental Bonding Instrument (PBI) have been used to retrospectively investigate parent-child relationships. Blood samples were collected to determine HVA, PRL, ACTH and cortisol basal plasma levels. RESULTS Cocaine addicted individuals in general showed significantly lower HVA, and higher PRL, ACTH and cortisol basal levels respect to controls. In particular, neuroendocrine changes characterized cocaine addicts with childhood history of neglect and low perception of parental care. Obsessive-compulsive, depression and aggressiveness symptoms have been found related to poor parenting, inversely associated to HVA levels and directly associated to PRL, ACTH and cortisol levels. CONCLUSIONS These findings suggest the possibility that childhood experience of neglect and poor parent-child attachment may partially contribute to a complex neurobiological derangement including HPA axis and dopamine system dysfunctions, playing a crucial role in addictive and affective disorders susceptibility.

Homovanillic acid (HVA) plasma levels inversely correlate with attention deficit-hyperactivity and childhood neglect measures in addicted patients. J Neural Transm (Vienna) 2007; 114:1637-47.

Abstract
BACKGROUND Attention deficit hyperactivity disorder (ADHD) seems to be a risk condition for substance use disorders, possibly in relationship to common neurobiological changes, underlying both addictive and externalising behaviour susceptibility. Although this vulnerability has been primarily attributed to gene variants, previous studies suggest that also adverse childhood experiences may influence neurotransmission, affecting in particular brain dopamine (DA) system and possibly concurring to the development of behavioural disorders. Therefore, we decided to investigate ADHD symptoms and plasma concentrations of the DA metabolite homovanillic acid (HVA) in abstinent addicted patients, in comparison with healthy control subjects, evaluating whether ADHD scores were related with HVA levels, as expression of DA turnover, and whether HVA values, in turn, were associated with childhood emotional neglect. METHODS Eighty-two abstinent drug dependent patients, and 44 normal controls, matched for age and sex, completed the Wender Utah Rating Scale (WURS), measuring ADHD symptoms, and the Childhood Experience of Care and Abuse Questionnaire (CECA-Q). Blood samples were collected to determine HVA plasma levels. RESULTS Addicted individuals showed significantly higher ADHD scores and lower HVA levels respect to control subjects. ADHD scores at WURS in addicted patients negatively correlated with plasma HVA values. In turn, plasma HVA levels were inversely associated with childhood neglect measures, reaching statistical significance with "mother-antipathy" and "mother neglect" scores. CONCLUSIONS These findings suggest the possibility that childhood experience of neglect and poor mother-child attachment may have an effect on central dopamine function as an adult, in turn contributing to both ADHD and substance abuse neurobiological vulnerability.
