Ambipolar Pentacyclic Diamides with Interesting Electrochemical and Optoelectro...
Burke, aNTHONY; Marques, CS; Ramalho, JP; Branco, L; Gago, Sandra; Cruz, Hugo; Lawrence, S; Morgado, JDeveloping organic semiconductors for organic thin film transistors (OTFT) and optoelectronic applications is a challenge. We developed highly crystalline pentacyclic diimides (3) and (4) which showed good OTFT and OLED potential and energy gaps of 2.60 eV and 2.54 eV. They exhibited interesting photo and eletroluminescence activity. Both compounds showed good quantum yields (0.56 for (3) and 0.60 for (4)).
Comprehensive perspective for lung cancer characterisation based on AI solution...
Pereira, T; Freitas, C; Costa, JL; Morgado, J; Silva, F; Negrão, E; Lima, BF; Silva, MC; Madureira, AJ; Ramos, I; Hespanhol, V; Cunha, A; Oliveira, HPLung cancer is still the leading cause of cancer death in the world. For this reason, novel approaches for early and more accurate diagnosis are needed. Computer-aided decision (CAD) can be an interesting option for a noninvasive tumour characterisation based on thoracic computed tomography (CT) image analysis. Until now, radiomics have been focused on tumour features analysis, and have not considered the infor...
Sharing biomedical data: Strengthening ai development in healthcare
Pereira, T; Morgado, J; Silva, F; Pelter, MM; Dias, VR; Barros, R; Freitas, C; Negrão, E; Lima, BF; Silva, MC; Madureira, AJ; Ramos, I; Hespanhol, VArtificial intelligence (AI)-based solutions have revolutionized our world, using extensive datasets and computational resources to create automatic tools for complex tasks that, until now, have been performed by humans. Massive data is a fundamental aspect of the most powerful AI-based algorithms. However, for AI-based healthcare solutions, there are several socioeconomic, technical/infrastructural, and most i...
EGFR Assessment in Lung Cancer CT Images: Analysis of Local and Holistic Region...
Silva, F; Pereira, T; Morgado, J; Frade, J; Mendes, J; Freitas, C; Negrao, E; Lima, BF; Silva, M; Madureira, AJ; Ramos, I; Hespanhol, V; Costa, JLStatistics have demonstrated that one of the main factors responsible for the high mortality rate related to lung cancer is the late diagnosis. Precision medicine practices have shown advances in the individualized treatment according to the genetic profile of each patient, providing better control on cancer response. Medical imaging offers valuable information with an extensive perspective of the cancer, openi...
Machine learning and feature selection methods for egfr mutation status predict...
Morgado, J; Pereira, T; Silva, F; Freitas, C; Negrão, E; Lima, BF; Silva, MC; Madureira, AJ; Ramos, I; Hespanhol, V; Costa, JL; Cunha, A; Oliveira, HPThe evolution of personalized medicine has changed the therapeutic strategy from classical chemotherapy and radiotherapy to a genetic modification targeted therapy, and although biopsy is the traditional method to genetically characterize lung cancer tumor, it is an invasive and painful procedure for the patient. Nodule image features extracted from computed tomography (CT) scans have been used to create machin...
Language Improvement One Week After Thrombolysis in Acute Stroke
Martins, IP; Fonseca, J; Morgado, J; Leal, G; Farrajota, L; Fonseca, AC; Melo, TPOBJECTIVES: Language recovery following acute stroke is difficult to predict due to several evaluation factors and time constraints. We aimed to investigate the predictors of aphasia recovery and to identify the National Institute of Health and Stroke Scale (NIHSS) items that best reflect linguistic performance, 1 week after thrombolysis. MATERIALS AND METHODS: We retrieved data from a prospective registry of p...
Epilepsy and physical exercise
Pimentel, J; Tojal, R; Morgado, JEpilepsy is one of the commonest neurologic diseases and has always been associated with stigma. In the interest of safety, the activities of persons with epilepsy (PWE) are often restricted. In keeping with this, physical exercise has often been discouraged. The precise nature of a person's seizures (or whether seizures were provoked or unprovoked) may not have been considered. Although there has been a change...

Multiple sclerosis and motherhood choice: an observational study in Portuguese ...
Carvalho, A; Veiga, A; Morgado, J; Tojal, R; Rocha, S; Vale, J; Sa, MJ; Timoteo, AINTRODUCTION. Multiple sclerosis (MS) is a disabling disease occurring mainly in women of childbearing age. MS may interfere with family planning and motherhood decision. AIM. To study the influence of MS diagnosis and course of the disease on motherhood decision. PATIENTS AND METHODS. The cohort of 35 to 45-year-old female patients diagnosed with MS for at least ten years was selected from six Portuguese MS ce...
Esclerosis múltiple y decisión de la maternidad: estudio observacional en pacie...
Carvalho, A; Veiga, A; Morgado, J; Tojal, R; Rocha, S; Vale, J; Sá, MJ; Timóteo, AIntroducción. La esclerosis múltiple (EM) es una enfermedad incapacitante que afecta mayoritariamente a mujeres en edad fértil. La EM puede alterar el deseo de crear una familia y concebir hijos. Objetivo. Estudiar la influencia del diagnóstico de la EM y de su evolución sobre la decisión de ser madre. Pacientes y métodos. Se seleccionó una cohorte integrada por pacientes de 35-45 años diagnosticadas de EM desd...
