Intra-Nasally Administered Oligopeptide Lunasin Acts as a Possible Anti-Psychotic Agent in Mice Models
2019
Background and Objectives: Previously we have shown that synthetic lunasin, a 43 amino acid residue-containing peptide, after its central (intracisternal) administration in mice demonstrated antagonism against dopaminergic drug behavioural effects, indicating a putative antipsychotic/anti-schizophrenic profile of lunasin. The aims of the present studies were: to test whether lunasin would show an influence on the dopaminergic system after intranasal administration, and to examine the effect(s) of lunasin on serotonin and glutamatergic systems, which could play an essential role in antipsychotic action. Materials and Methods: Lunasin was administered intra-nasally at doses 0.1 and 1 nmol/mou…
Die nächste Generation „atypischer” Antipsychotika: Der Beitrag der Positronenemissionstomographie
2003
Almost fifteen years of research with Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT) have led to a profound understanding of the relationships between antipsychotic doses and plasma levels on the one hand and occupancy of (striatal) D 2 -like dopamine receptors on the other hand as well as with the associated clinical effects and side effects. Furthermore, with the development of clinically atypical" antipsychotics PET studies helped to generate hypotheses regarding the essential pharmacological properties of this heterogeneous class of drugs. Possible mechanisms of action include combined D 2 -/5-HT 2 antagonism, preferential mesolimbic binding, a…
The effects of personality on earnings
2005
Abstract The purpose of this paper is to investigate the influence of personality dimensions on wage settings. The study was inspired by the model proposed by Bowles, Gintis, and Osborne [American Economic Review 91 (2001) 155], which shows how psychological characteristics may be rewarded or punished in the labour market due to a so-called incentive-enhancing property. Additionally, two meta-studies show that there are robust relationships between some personality dimensions and productivity [Barrick & Mount, Personnel Psychology 44 (1991) 1; Salgado, Journal of Applied Psychology 82 (1997) 30]. We used data from the DNB Household Survey (DHS) to test the extent to which certain personalit…
Comparison between micellar liquid chromatography and capillary zone electrophoresis for the determination of hydrophobic basic drugs in pharmaceutic…
2007
[EN] The determination of highly hydrophobic basic compounds by means of conventional reversed-phase liquid chromatographic methods has several drawbacks. Owing to the characteristics of micellar liquid chromatography (MLC) and capillary electrophoresis (CE), these techniques could be advantageous alternatives to reversed-phase chromatographic methods for the determination of these kinds of compounds. The objective of this study was to develop and compare MLC and CE methods for the determination of antipsychotic basic drugs (amitryptiline, haloperidol, perphenazine and thioridazine) in pharmaceutical preparations. The chromatographic determination of the analytes was performed on a Kromasil…
MONITORING OF ATYPICAL ANTIPSYCHOTIC DRUGS SUPPLIED BY THE PHARMACY OF FRATELLI PARLAPIANO HOSPITAL, RIBERA (AG), ITALY
2014
Mental disorders are among the worst and widespread health problems, they are associated with important repercussions on the psychosocial sphere and to high economic costs. Antipsychotic drugs used in treatments of these pathologies belong to different chemical classes, but associated to biochemical effects, pharmacological, and in part super imposable. A retrospective survey has been led on external patients, they were under antipsychotic drug treatments already in the archive and arrived to the attention of the Pharmacy of the F.lli Parlapiano Hospital, Ribera (AG), Italy in 2013. For each patient have been extrapolated: gender, date of birth, place of residence, ICD-9CM, pharmacological …
Clinical correlates of paliperidone palmitate and aripiprazole monohydrate prescription for subjects with schizophreniaspectrum disorders: Findings f…
2020
This study, based on the 'Servizi Territoriali Associati per la Ricerca' (STAR) Network Depot Study nationwide baseline data, explored whether individual symptoms severity and clusters might influence the prescription of paliperidone palmitate 1-month (PP1M) vs. aripiprazole monohydrate. The Brief Psychiatric Rating Scale (BPRS) was used to assess psychopathology and relevant symptoms clusters. Drug Attitude Inventory, 10 items, was used to test attitude towards medications. Adherence to treatments was rated according to the Kemp seven-point scale. We assessed for eligibility 451 individuals and, among them, we included 195 subjects (n = 117 who started PPM1 and n = 78 aripiprazole monohydr…
Atypical Antipsychotics in the Treatment of Acute Bipolar Depression with Mixed Features: A Systematic Review and Exploratory Meta-Analysis of Placeb…
2016
Evidence supporting the use of second generation antipsychotics (SGAs) in the treatment of acute depression with mixed features (MFs) associated with bipolar disorder (BD) is scarce and equivocal. Therefore, we conducted a systematic review and preliminary meta-analysis investigating SGAs in the treatment of acute BD depression with MFs. Two authors independently searched major electronic databases from 1990 until September 2015 for randomized (placebo-) controlled trials (RCTs) or open-label clinical trials investigating the efficacy of SGAs in the treatment of acute bipolar depression with MFs. A random-effect meta-analysis calculating the standardized mean difference (SMD) between SGA an…
Factor analyses of multidimensional symptoms in a large group of patients with major depressive disorder, bipolar disorder, schizoaffective disorder …
2020
Abstract Background There is an ongoing discussion about which neurobiological correlates or symptoms separate the major psychoses (i.e. Major Depressive Disorder MDD, Bipolar Disorder BD, and Schizophrenia SZ). Psychopathological factor analyses within one of these disorders have resulted in models including one to five factors. Factor analyses across the major psychoses using a comprehensive set of psychopathological scales in the same patients are lacking. It is further unclear, whether hierarchical or unitarian models better summarize phenomena. Method Patients (n = 1182) who met DSM-IV criteria for MDD, BD, SZ or schizoaffective disorder were assessed with the SANS, SAPS, HAMA, HAM-D, …

Sexual Dysfunction and Mood Stabilizers in Long-Term Stable Patients With Bipolar Disorder.
2020
Abstract Background In addition to factors intrinsic to bipolar disorder (BD), sexual functioning (SF) can be affected by extrinsic causes, such as psychotropic drugs. However, the effect of mood stabilizers on SF and quality of life (QoL) is an underexplored research area. Aim To analyze SF in BD outpatients in euthymia for at least 6 months treated only with mood stabilizers and the association between SF and QoL. Methods A multicenter cross-sectional study was conducted in 114 BD outpatients treated with (i) lithium alone (L group); (ii) anticonvulsants alone (valproate or lamotrigine; A group); (iii) lithium plus anticonvulsants (L+A group); or (iv) lithium plus benzodiazepines (L+B gro…
