Effects of psychosis-associated genetic markers on brain volumetry: a systemati...
Vouga Ribeiro, Nuno; Tavares, Vânia; Bramon, Elvira; Toulopoulou, Timothea; Valli, Isabel; Shergill, Sukhi; Murray, Robin; Prata, DianaBackground: Given psychotic illnesses' high heritability and associations with brain structure, numerous neuroimaging-genetics findings have been reported in the last two decades. However, few findings have been replicated. In the present independent sample we aimed to replicate any psychosis-implicated SNPs (single nucleotide polymorphisms), which had previously shown at least two main effects on brain volume....
Onset probability prediction of schizophrenia based on a multimodal approach
Tavares, VâniaPsychosis is a severe mental condition characterized by a complex set of disturbances of thinking, perception, affect and social behaviour. It is usually preceded by a prodromal phase lasting months to years and in which patients are clinically identified has being ‘At Risk Mental State’ (ARMS). Retrospective studies have showed that ARMS individuals have a 30% risk of transition to psychosis within the first 2...
Pupil dilation reflects the authenticity of received nonverbal vocalizations
Cosme, Gonçalo; Rosa, Pedro Joel; Lima, César; Tavares, Vânia; Scott, Sophie; Chen, Sinead; Wilcockson, Thomas; Crawford, Trevor; Prata, DianaThe ability to infer the authenticity of other’s emotional expressions is a social cognitive process taking place in all human interactions. Although the neurocognitive correlates of authenticity recognition have been probed, its potential recruitment of the peripheral autonomic nervous system is not known. In this work, we asked participants to rate the authenticity of authentic and acted laughs and cries, whi...
Cultural differences in vocal emotion recognition: a behavioural and skin condu...
Cosme, Gonçalo; Tavares, Vânia; Nobre, Guilherme; Lima, César; Sá, Rui Miguel Moutinho; Rosa, Pedro Joel; Prata, DianaCross-cultural studies of emotion recognition in nonverbal vocalizations not only support the universality hypothesis for its innate features, but also an in-group advantage for culture-dependent features. Nevertheless, in such studies, differences in socio-economic-educational status have not always been accounted for, with idiomatic translation of emotional concepts being a limitation, and the underlying psyc...
Sex differences in functional connectivity between resting state brain networks...
Tavares, Vânia; Fernandes, Luís Afonso; Antunes, Marilia; Ferreira, Hugo; Prata, DianaFunctional brain connectivity (FBC) has previously been examined in autism spectrum disorder (ASD) between-resting-state networks (RSNs) using a highly sensitive and reproducible hypothesis-free approach. However, results have been inconsistent and sex differences have only recently been taken into consideration using this approach. We estimated main effects of diagnosis and sex and a diagnosis by sex interacti...

Pré-tratamento de água através de separador centrífugo para aplicação em filtra...
Tavares, VâniaDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia Ambiental.; A pesquisa teve por objetivo o estudo da aplicação do separador centrífugo como pré-tratamento de água de abastecimento, visando a estabelecer o efeito positivo da ação da força centrífuga, na retirada de partículas sólidas não dissolvidas e na tentativa de obter redução no ní...
