EBV and MSI status in gastric cancer: does it matter?
Nascimento, Catarina Neto do; Mascarenhas-Lemos, Luís; Silva, João Ricardo; Marques, Diogo Sousa; Gouveia, Catarina Ferreira; Faria, Ana; Velho, SóniaWe investigated the impactof microsatellite instability (MSI) and Epstein–Barr virus (EBV) status in gastric cancer (GC), regarding response to perioperative chemotherapy (POPChT), overall survival (OS), and progression-free survival (PFS). We included 137 cases of operated GC, 51 of which were submitted to POPChT. MSI status was determined by multiplex PCR and EBV status by EBV-encoded RNA in situ hybridizatio...
Role of endoscopic biopsies and morphologic features in predicting microsatelli...
Silva, João R.; Mascarenhas-Lemos, Luís; Neto do Nascimento, Catarina; Sousa Marques, Diogo; Wen, Xiaogang; Pinho, Lídia; Maio, Rui; Pontes, PatríciaEvaluation of mismatch repair (MMR) protein and microsatellite instability (MSI) status plays a pivotal role in the management of gastric cancer (GC) patients. In this study, we aimed to evaluate the accuracy of gastric endoscopic biopsies (EBs) in predicting MMR/MSI status and to uncover histopathologic features associated with MSI. A multicentric series of 140 GCs was collected retrospectively, in which EB an...

Advanced Technologies for Oral Controlled Release: Cyclodextrins for oral contr...
Salústio, Paulo José; Pontes, Patrícia; Conduto, Cláudia; Sanches, Inês; Carvalho, Catarina; Arrais, João; Cabral Marques, Helena MCyclodextrins (CDs) are used in oral pharmaceutical formulations, by means of inclusion complexes formation, with the following advantages for the drugs: (1) solubility, dissolution rate, stability and bioavailability enhancement; (2) to modify the drug release site and/or time profile; and (3) to reduce or prevent gastrointestinal side effects and unpleasant smell or taste, to prevent drug-drug or drug-additiv...
