Medeiros, Catarina; Silva, Ana Rita; Ferreira, Tiago; Barros, Lillian; Neuparth, Maria João; Peixoto, Francisco P.; Bastos, Margarida M.S.M.Infections with certain types of papillomavirus, such as the human papillomavirus 16 (HPV16), are associated with the development of preneoplastic lesions and cancers of the anogenital, and head and neck regions. Cytinus hypocistis (L.) L. extracts are composed of substances presenting antiproliferative, antioxidant, anti-inflammatory and antibacterial properties, which might be promising as new therapeutic com...

Nascimento-Gonçalves, Elisabete; Seixas, Fernanda; Palmeira, Carlos; Martins, Gabriela; Fonseca, Carolina; Duarte, José Alberto; Faustino-Rocha, Ana IThis work aimed to understand how lifelong exercise training promotes the remodelling of the immune system and prostate signalome in a rat model of PCa. Fifty-five male Wistar rats were divided into four groups: control sedentary, control exercised, induced PCa sedentary and induced PCa exercised. Exercised animals were trained in a treadmill for 53 weeks. Pca induction consisted on the sequential administratio...
