BACKGROUND: le caratteristiche cognitive e genetiche sono sempre più centrali nello studio della Schizofrenia. La compromissione delle Funzioni Esecutive (FE), definite come un complesso di abilità cognitive superiori attribuibili alle regioni della corteccia prefrontale, e della Facial Emotion Recognition (FER) rappresentano elementi centrali nel disturbo schizofrenico. Ad oggi, però, il paradigma del (dis)funzionamento cognitivo nella Schizofrenia poggia su studi che hanno escluso i soggetti schizofrenici con storia di abuso di sostanze (SUD), che ha mostrato un impatto peggiorativo sulla co

Abstract:

Catechol-O-methyltransferase (COMT, EC 2.1.1.6) is an S-adenosyl-L-methionine-dependent methyltransferase enzyme that catalyzes the methylation of catechol substrates (catecholamines, catecholestrogens). Physiologically, it is responsible for the elimination of biologically active or toxic catechols, making it a protein with great clinical relevance as therapeutic target in serious disorders, like schizophrenia and Parkinson´s disease. To fulfill pharmaceuticals requirements, new strategies of optimization and large-scale production of COMT enzyme are crucial. Statistical optimization approach

First, as part of a study investigating the role of COMT in schizophrenia, human hippocampal COMT mRNA levels were shown to be neither altered in schizophrenia or bipolar disease, nor affected by COMT genotype.

The metabolism of MDMA is thought to be a necessary component of MDMA-induced neurotoxicity, as direct administration of MDMA into the central nervous system of rats failed to reproduce the hallmark serotonin deficits seen following systemic administration of MDMA. Mechanistic questions remain regarding how MDMA elicits this neurotoxicity.

The frontostriatal dopamine system modulates brain function and is affected by both genetic and environmental factors. Dysfunction of this system is associated with many pathological states, including schizophrenia. The enzyme catechol-O- methyltransferase (COMT) metabolises dopamine and its gene contains a polymorphism (Val<sup>158</sup>Met) that affects enzyme activity. Delta-9- tetrahydrocannabinol (THC), the main psychoactive component of cannabis, has been suggested to interact with this polymorphism to increase the risk for psychosis and cognitive impairments.

Abstract:

Fine temporal regulation of dopamine transmission is critical to its effects on behaviour. Dopamine can be cleared from the synapse either by recycling via the dopamine transporter (DAT) or by enzymatic degradation involving catechol-O-methyltransferase (COMT). DAT recycling predominates in striatum and contributes to dopaminergic regulation of reward-guided behaviour, while COMT degradation predominates in cortex and modulates executive functions. However, human functional imaging studies demonstrate interactive effects of DAT and COMT genotype, suggesting that the traditional division betwee

Abstract:

Research on neurocognitive aspects in Anorexia Nervosa (AN) has outlined a cognitive profile characterized by deficiency in the ability to set-shifting (cognitive flexibility) and weak central coherence. A smaller agreement emerges in relation to the compromission of decisional profiles frequently observed in patients with AN since both the complexity of the pathology and the executive function itself make it unclear the nature of these alterations and its relationships with specific or independent clinical and enviornmental variables. The aim of this study was: to investigate different types

Abstract:

Delay Discounting im Sinne eines Abwertens zukünftiger Belohnungen ist ein weit verbreitetes Phänomen. Es zeigt sich z. B. in persönlichen Angelegenheiten, wie der Entscheidung für den kurzfristigen Genuss von Süßigkeiten und gegen die langfristigen, durchaus größeren Vorteile einer schlanken Figur. Auch internationale wirtschaftliche und politische Diskussionen zum Klimaschutz oder der Finanzkrise werden von der Präferenz für sofortige, kleinere Belohnungen über verzögerte, größere Belohnungen getrieben. In der Psychologie wird Delay Discounting als Maß für Impulsivität bzw. Selbstkontrolle m

As plantas medicinais são consideradas importantes fontes de compostos biologicamente ativos. Para muitas doenças crônicas, como as neurodegenerações, substâncias que apresentam atividades simultâneas em mais de um alvo relacionado à etiopatologia dessas desordens, constituem potenciais agentes terapêuticos. Nesse contexto, os objetivos deste trabalho foram a avaliação química e biológica de três espécies de samambaias de ocorrência no sul do Brasil: Blechnum binervatum, B. brasiliense e B. occidentale. O isolamento bioguiado foi utilizado para a identificação da(s) substância(s) com potencial

Abstract:

O Transtorno obsessivo-compulsivo (TOC) é um transtorno psiquiátrico comum e heterogêneo caracterizado por obsessões (pensamentos, imagens ou impulsos intrusivos e recorrentes) e compulsões (comportamentos ou atos mentais repetitivos realizados para aliviar as obsessões). O TOC tem uma prevalência de 2 a 3% na população geral e apresenta distribuição aproximadamente igual entre os sexos, porém os homens tendem a apresentar os sintomas obsessivo-compulsivos mais precocemente quando comparado com as mulheres. Os estudos de genética epidemiológica têm demonstrado que o fator genético é um importa

Abstract:

Decades of research in quantitative genetics have found substantial heritability for personality traits as well as for mental disorders which formed the basis of the ongoing molecular genetic studies that aim to identify genetic variations that actually contribute to the manifestation of complex traits. With regard to psychological traits, genetic variation impacting neurotransmitter function have been of particular interest. Additionally, the role of environmental factors including gene × environment interactions has been further investigated and the impor-tance of developmental aspects has b

Abstract:

D'entre totes les catecolamines, la dopamina és la més important del sistema nerviós central, on regula funcions com la conducta motora, les emocions i la cognició. Donada la implicació del sistema dopaminèrgic en diverses disfuncions cerebrals, com ara l'esquizofrènia, la malaltia de Parkinson o el trastorn per dèficit d'atenció amb hiperactivitat, l'estudi d'aquest sistema ha esdevingut de gran importància. Els dos mecanismes més importants de terminació de l'activitat dopaminèrgica a nivell sinàptic són la recaptació mitjançant el transportador de la dopamina (DAT) i la degradació a través

Abstract:

Children born very preterm are exposed to repeated neonatal procedures that induce pain and stress during hospitalization in the neonatal intensive care unit (NICU). The COMT Val158Met genotype is involved with pain sensitivity, and early life stress is implicated in altered expression of methylation of the serotonin transporter. We examined: (1) whether methylation of the serotonin transporter gene (SLC6A4) promoter differs between very preterm children and full-term controls at school age, (2) relationships with child behavior problems, and (3) whether the extent of neonatal pain exposure in
