Analysis of phenolic compounds in leaves from endemic trees from Madeira Island...
Llorent-Martínez, Eulogio J.; Gouveia, Sandra; Castilho, Paula C.Phenolic compounds present high antioxidant activity and, therefore, health promoting effects, serving as a type of preventive medicine. Hence, research on the chemical composition of plants with potential antioxidant value is of high interest. Forest cleaning, thinning, and pruning are beneficial activities that help maintaining healthy forests. In addition, they can provide vegetal material as source of valua...

Primary effusion lymphoma in a HIV infected patient
Gouveia, Sandra; Castro, Marco; Correia, Ruth; Germano, Isabel; Farrajota, FranciscoThe primary lymphoma of cavities is a rare subtype of non-Hodgkin (NHL) with reserved prognosis, characterized by the proliferation of malignant cells exclusively in serosal cavities and is associated with infection by type 8 human herpes virus. It is more often described in immunosuppressed patients, particularly in the context of Acquired Immunodeficiency Syndrome (AIDS).We present a case of a patient diagnos...
HIV infection diagnosis – What changed in 10 years
Carlos, Andreia; Gouveia, SandraIntroduction: The HIV infection / AIDS is still an important cause of morbidity and mortality in developing countries, where only a restricted number of patients have antiretroviral therapy available. In developed countries there is a trend to epidemics stabilization. Nevertheless, late stage diagnosis is still very frequent, overcoming the benefits of treatment early onset. Portugal is the Western European cou...
