- Impact of splenic artery ligation after major hepatectomy on liver function, regeneration and viabilityPublication . Carrapita, J; Abrantes, AM; Campelos, S; Gonçalves, AC; Cardoso, D; Sarmento-Ribeiro, AB; Rocha, C; Santos, JN; Botelho, MF; Tralhão, JG; Farges, O; Barbosa, JMIt was reported that prevention of acute portal overpressure in small-for-size livers by inflow modulation results in a better postoperative outcome. The aim is to investigate the impact of portal blood flow reduction by splenic artery ligation after major hepatectomy in a murine model. Forty-eight rats were subjected to an 85% hepatectomy or 85% hepatectomy and splenic artery ligation. Both groups were evaluated at 24, 48, 72 and 120 post-operative hours: liver function, regeneration and viability. All methods and experiments were carried out in accordance with Coimbra University guidelines. Splenic artery ligation produces viability increase after 24 h, induces a relative decrease in oxidative stress during the first 48 hours, allows antioxidant capacity increment after 24 h, which is reflected in a decrease of half-time normalized liver curve at 48 h and at 72 h and in an increase of mitotic index between 48 h and 72 h. Splenic artery ligation combined with 85% hepatectomy in a murine model, allows portal inflow modulation, promoting an increase in hepatocellular viability and regeneration, without impairing the function, probably by inducing a less marked elevation of oxidative stress at first 48 hours.
- Prevalence of antibodies to a new histo-blood system: the FORS systemPublication . Jesus, C; Hesse, C; Rocha, C; Osório, N; Valado, A; Caseiro, A; Gabriel, A; Svensson, L; Moslemi, AR; Siba, WA; Srour, MA; Pereira, C; Tomaz, J; Teixeira, P; Mendes, FIn 1987, three unrelated English families were reported with a putative blood subgroup called Apae. Swedish researchers later found evidence leading to abolishment of the Apae subgroup and establishment instead of the FORS blood group system (System 31 - ISBT, 2012). It is important to know the prevalence of antibodies in order to make the best decisions in transfusion medicine. Cells expressing the Forssman saccharide, such as sheep erythrocytes, are needed to detect the anti-Forssman antibody. The aim of this study was to define the prevalence of human anti-Forssman antibody.
