1. DRD4 genotyping may differentiate symptoms of attention-deficit/hyperactivity disorder and sluggish cognitive tempo
Objective: Studies to reduce the heterogeneity of attention-deficit/hyperactivity disorder (ADHD) have increased interest in the concept of sluggish cognitive tempo (SCT). The aim of this study was to investigate if the prevalence of two variable-number tandem repeats (VNTRs) located within the 3′-untranslated region of the DAT1 gene and in exon 3 of the

2. Evaluation of association of DRD2 TaqIA and -141C InsDel polymorphisms with food intake and anthropometric data in children at the first stages of development
Abstract The reward sensation after food intake may be different between individuals and variants in genes related to the dopaminergic system may indicate a different response in people exposed to the same environmental factors. This study investigated the association of TaqIA (rs1800497) and -141C InsDel (rs1799732) variants in DRD2/ANKK1 gene with food int

3. Epistasis between COMT Val158Met and DRD3 Ser9Gly polymorphisms and cognitive function in schizophrenia: genetic influence on dopamine transmission
Objective:To assess the relationship between cognitive function, a proposed schizophrenia endophenotype, and two genetic polymorphisms related to dopamine function, catechol-O-methyl transferase (COMT) Val158Met and dopamine receptor 3 (DRD3) Ser9Gly.Methods:Fifty-eight outpatients with schizophrenia/schizoaffective disorder and 88 healthy controls underwent

4. Abundant immunohistochemical expression of dopamine D2 receptor and p53 protein in meningiomas: follow-up, relation to gender, age, tumor grade, and recurrence
Meningiomas are common, usually benign tumors, with a high postoperative recurrence rate. However, the genesis and development of these tumors remain controversial. We aimed to investigate the presence and implications of a mutated p53 protein and dopamine D2 receptor in a representative series of meningiomas and to correlate these findings with age, gender,

5. Antidepressant-like effect of Hoodia gordonii in a forced swimming test in mice: evidence for involvement of the monoaminergic system
Hoodia gordonii is a plant species used traditionally in southern Africa to suppress appetite. Recently, it has been associated with a significant increase in blood pressure and pulse rate in women, suggesting sympathomimetic activity. The present study investigated the possible antidepressant-like effects of acute and repeated (15 days) administration of H

6. 6-Hydroxydopamine lesions in the medial prefrontal cortex of rats exposed to a peak-interval procedure
Impaired temporal control is symptomatic of several neurological disorders; recently, it has been implicated in schizophrenia. An animal model of schizophrenia using 6-hydroxydopamine (6-OHDA) infused to the medial pre-frontal cortex (mPFC) was employed to examine its effects on temporal control. Twelve rats were trained on a peak-interval procedure (PIP) un

7. Influence of the dopaminergic system, CREB, and transcription factor-κB on cocaine neurotoxicity
Cocaine is a widely used drug and its abuse is associated with physical, psychiatric and social problems. Abnormalities in newborns have been demonstrated to be due to the toxic effects of cocaine during fetal development. The mechanism by which cocaine causes neurological damage is complex and involves interactions of the drug with several neurotransmitter

8. ANÁLISE DA EXPRESSÃO DOS RECEPTORES DA SOMATOSTATINA (SST1-5) E DA DOPAMINA (DR2) EM ADENOMAS HIPOFISÁRIOS / ANALYSIS OF EXPRESSION OF THE RECEPTORS OF THE SOMATOSTATIN (SST1-5) AND DOPAMINE (DR2) IN PITUITARY ADENOMAS
Pituitary tumors represent 15% of intracranial neoplasms and are usually benign. The treatment primary is surgical resection with exception for prolactinomas because dopamine agonists are very effective in the treatment these tumors. If surgery does not lead to healing, it is necessary other therapeutic strategy in a attempt to control hormone levels and tum

9. Análise dos polimorfismos 3420 e 3438 no gene do receptor da dopamina D2 em mulheres com diferentes desfechos reprodutivos : endometriose e aborto de repetição
Introdução: O aumento do nível sérico de prolactina tem sido associado com desfechos ginecológicos e obstétricos desfavoráveis, entre eles a endometriose e aborto recorrente. Sabendo que o polimorfismo do receptor da dopamina D2 (DRD2) está associado com hiperprolactinemia, realizamos este estudo para verificar sua associação com endometriose e com

10. Nicotine receptor partial agonists for smoking cessation
BACKGROUND: Nicotine receptor partial agonists may help people to stop smoking by a combination of maintaining moderate levels of dopamine to counteract withdrawal symptoms (acting as an agonist) and reducing smoking satisfaction (acting as an antagonist). OBJECTIVES: The primary objective of this review is to assess the efficacy and tolerability of nicotine

11. Efeitos da ovariectomia e treinamento de força na concentração tecidual de dopamina e serotonina na via nigroestriatal e mesolímbica de ratas
O estrogênio é um hormônio esteróide conhecido por representar um papel relevante nos eventos celulares do desenvolvimento, manutenção da fisiologia do corpo e ações moduladoras no sistema nervoso central (SNC) durante a vida. O objetivo do presente estudo foi investigar o efeito da ovariectomia (OVX) e da intervenção do treinamento de força sobre

12. Efeitos a longo prazo de diferentes separações dos filhotes no período neonatal sobre as genitoras
Esse estudo foi realizado para verificar se a exposição a separações repetidas (por diferentes intervalos de tempo) de mães dos seus filhotes no período neonatal poderiam ser classificadas como indutoras de um estado do tipo deprimido em genitoras. Sessenta ratas Wistar prenhes foram divididas em 3 grupos: controle, separação por 10 minutos e separa�
