Common genetic polymorphisms in the ABCB1 gene are associated with risk of majo...
Santos, Marlene; Carvalho, Serafim; Lima, Luís; Nogueira, Augusto; Assis, Joana; Mota-Pereira, Jorge; Pimentel, Paulo; Maia, Dulce; Correia, DianaMajor depressive disorder (MDD) is a highly prevalent disorder, which has been associated with an abnormal response of the hypothalamus–pituitary–adrenal (HPA) axis. Reports have argued that an abnormal HPA axis response can be due to an altered P-Glycoprotein (P-GP) function. This argument suggests that genetic polymorphisms in ABCB1 may have an effect on the HPA axis activity; however, it is still not clear i...
Pelvic Fracture – Generic notions for the general surgeon
Pereira, Jorge; Cirurgião Geral, Serviço de Cirurgia 1 – Centro Hospitalar Tondela-Viseu, PortugalThe pelvic fracture consists on a clinical entity that can represent grave danger, mainly when associated to major mechanic instability, which reflects the amount of energy transferred during trauma. The high mortality of pelvic fracture is a reason for concern to the medical staff involved in its management, because its multiple needs, in terms of assessment and treatment. The general surgeon is often responsi...
Densidade Mineral Óssea em Adolescentes Portugueses
Rego, Cada; Guerra, António; Pereira, Jorge; Silva, Diana; Lourenço, Susana; Ramos, Isabel; Santos, Norberto TeixeiraIntrodução: A osteoporose é hoje considerada um grave problema de saúde pública nos países desenvolvidos, não só devido ao elevado índice de absentismo ao trabalho que condiciona, mas também aos elevados custos que acarreta. Embora as manifestações clínicas ocorram apenas na idade adulta, a osteoporose é uma doença com início na idade pediátrica, consistindo pois a prevenção na melhor arma terapêutica disponíve...
Is axenicity crucial to cryopreserve microalgae?
Amaral, Raquel; Pereira, Jorge C.; Pais, Alberto A. C. C.; Santos, Lília M. A.Large culture collections of microalgae and cyanobacteria such as the Coimbra Collection of Algae (ACOI) hold unialgal cultures consisting of a population of cells/colonies of a certain species. These cultures are usually non-axenic, as other organisms such as bacteria and microfungi are also present in culture due to co-isolation. Attention has been recently given to partner organisms since studies indicate th...
Desenvolvimento e estudo de modelos de FACTS para o trânsito de energia: aplica...
Pereira, Jorge Miguel PintoNesta dissertação são apresentados e desenvolvidos modelos de FACTS (SVC, Fixed Shunt, switched Shunt, STATCOM, etc) em regime permanente de forma a poder analisar o seu contributo para o controlo de tensão em sistemas de energia eléctrica. Para o efeito foi desenvolvido uma plataforma de simulação que permite o cálculo do trânsito de energia baseado no método de Newton-Raphson, com e sem a presença de FACTS. F...
Leveraging facebook’s open graph to develop an environmental persuasive applica...
Pereira, Jorge André HenriquesDissertação para obtenção do Grau de Mestre em Engenharia Informática ; Social networking sites persuade millions of users each day to adopt specific behaviors. Using the persuasive principles inherent to these sites to increase environmental awareness and reduce our ecological footprint can be challenging but certainly worthy. The DEAP project has already invested time and resources to address persuasion thro...
Relação entre a perceção da imagem corporal e a obesidade em adolescentes
Sá, Eduarda; Ferrão, Filipe; Guedes, Janete; Pereira, Jorge; Silva, L.; Pereira, Beatriz Oliveira; Carvalho, Graça Simões deO presente projeto tem como objetivo determinar a relação entre a imagem corporal (através da perceção que os adolescentes têm da sua aparência física) e o efetivo índice de massa corporal (IMC), coadjuvado com o perímetro abdominal. A amostra será constituída por cerca de 300 crianças e adolescentes de ambos os sexos e com idades compreendidas entre os 13 e os 18 anos de idade. A avaliação da perceção da image...
Moderate exercise as an adjuvant therapy for treatment-resistant major depressi...
Mota-Pereira, Jorge; Silvério, Jorge Manuel Amaral; Fonte, Daniela; Carvalho, Serafim; Ramos, Joaquim; Ribeiro, José CarlosAlthough several international guidelines recommend exercise to reduce symptoms of Major Depressive Disorder (MDD), data concerning the long-term effects of exercise in depression are still extremely scarce. Therefore, and in order to assess these long-term effects, we have evaluated treatment-resistant MDD patients previously enrolled in a moderate intensity 12 week exercise program at 3 and 6 months after...
Exercise intervention in treatment-resistant major depressive disorder : benefi...
Mota-Pereira, Jorge; Ribeiro, José Carlos; Fonte, Daniela; Carvalho, Serafim; Ramos, Joaquim; Silvério, Jorge Manuel AmaralAlthough there are several reports on the benefits of exercise on Major Depressive Disorder, none has monitored these exercise programs with accelerometers. We have conducted a 12 week home based moderate intensity exercise program in 33 treatmentresistant Major Depressive Disorder patients and, based on accelerometer data, determined compliance, exercise patterns and relationship between time spent in MVPA...
Ehanced oil recovery under simulated reservoir conditions using an indigenous B...
Gudiña, Eduardo J.; Pereira, Jorge F. B.; Costa, A. R.; Rodrigues, L. R.; Coutinho, J. A. P.; Teixeira, J. A.Microbial Enhanced Oil Recovery (MEOR) is potentially useful to increment oil recovery from reservoirs beyond primary and secondary recovery operations using microorganisms and their metabolites. In situ stimulation of microorganisms that produce biosurfactants and degrade heavy oil fractions reduces the capillary forces that retain the oil inside the reservoir and decreases oil viscosity, thus promoting its fl...
