Brain activation of the defensive and appetitive survival systems in obsessive ...
Gon??alves, ??scar F.; Soares, Jos?? Miguel; Carvalho, Sandra; Leite, Jorge; Gon??alves, Ana Fernandes; Frank, Brandon; Pocinho, MargaridaSeveral studies have shown that basic emotions are responsible for a significant enhancement of early visual processes and increased activation in visual processing brain regions. It may be possible that the cognitive uncertainty and repeated behavioral checking evident in Obsessive Compulsive Disorder (OCD) is due to the existence of abnormalities in basic survival circuits, particularly those associated with ...
Caracterização imunohistoquímica e molecular de amostras de endométrio de cadel...
Carvalho, Sandra Isabel Constantino Vieira deDissertação para obtenção do grau de Mestre em Biologia Molecular em Saúde ; A piómetra é uma doença de diestro comum em cadelas adultas, sendo Escherichia coli a bactéria mais frequentemente isolada. A resposta inflamatória é caracterizada pela produção de citocinas pró-inflamatórias e quimiocinas que contribuem para o recrutamento de células de reação inflamatória para o útero. Pretendeu-se com este estudo c...
Understanding the relationship between central metabolism and virulence in the ...
Carvalho, Sandra M.Dissertation presented to obtain the Ph.D. degree in Biochemistry ; Streptococcus pneumoniae is a normal inhabitant of the human nasopharynx, but it is better known for its role in a plethora of human diseases. Growing emergence of antibiotic-resistant streptococci and non-type vaccine strains increases the urgency of finding new targets for the development of novel therapeutic and preventive drugs. As a major...
Affective picture modulation : Valence, arousal, attention allocation and motiv...
Leite, Jorge; Carvalho, Sandra; Galdo-Álvarez, Santiago; Alves, Jorge; Sampaio, Adriana; Gonçalves, Óscar F.The present study analyses the modulatory effects of affective pictures in the early posterior negativity (EPN), the late positive potential (LPP) and the human startle response on both the peripheral (eye blink EMG) and central neurophysiological levels (Probe P3), during passive affective pictures viewing. The affective pictures categories were balanced in terms of valence (pleasant; unpleasant) and arousal (...
The emotional movie database (EMDB) : a self-report and psychophysiological study
Carvalho, Sandra; Leite, Jorge; Galdo-Álvarez, Santiago; Gonçalves, Óscar F.Film clips are an important tool for evoking emotional responses in the laboratory. When compared with other emotionally potent visual stimuli (e.g., pictures), film clips seem to be more effective in eliciting emotions for longer periods of time at both the subjective and physiological levels. The main objective of the present study was to develop a new database of affective film clips without auditory content...
Caracterização molecular de vírus do dengue sorotipo-1 e desenvolvimento de cDN...
Carvalho, Sandra Elisa de SousaTese (doutorado)—Universidade de Brasília, Faculdade de Medicina, Pós-Graduação em Patologia Molecular, 2009. ; Dengue é uma importante arbovirose causada pelo vírus do dengue (DENV; Família Flaviviridae, Gênero Flavivirus). Notável aumento no número de casos de dengue e dengue hemorrágica foi registrado nas Américas. Neste estudo foi descrito a diversidade de sequências de diferentes genomas completos de DE...
Task-specific effects of tDCS-induced cortical excitability changes on cognitiv...
Leite, Jorge; Carvalho, Sandra; Fregni, Felipe; Gonçalves, Óscar F.In this study, we tested the effects of transcranial Direct Current Stimulation (tDCS) on two set shifting tasks. Set shifting ability is defined as the capacity to switch between mental sets or actions and requires the activation of a distributed neural network. Thirty healthy subjects (fifteen per site) received anodal, cathodal and sham stimulation of the dorsolateral prefrontal cortex (DLPFC) or the primary...
Psychophysiological correlates of sexually and non-sexually motivated attention...
Carvalho, Sandra; Leite, Jorge; Galdo-Álvarez, Santiago; Gonçalves, Óscar F.Some authors have speculated that the cognitive component (P3) of the Event-Related Potential (ERP) can function as a psychophysiological measure of sexual interest. The aim of this study was to determine if the P3 ERP component in a workload task can be used as a specific and objective measure of sexual motivation by comparing the neurophysiologic response to stimuli of motivational relevance with different le...
Técnicas de reabilitação sem abertura de vala de redes de drenagem de águas res...
Carvalho, Sandra Maria RibeiroO objectivo da presente dissertação consiste na apresentação de várias técnicas de reabilitação de redes de drenagem de águas residuais sem necessidade de abertura de vala. Para esse efeito efectuou-se um levantamento das técnicas de reabilitação de colectores sem abertura de vala actualmente existente no mercado, tendo-se identificado cinco técnicas diferentes, organizadas em dois grandes grupo: Técnicas de e...
