- Apparent digestibility coefficients of processed agro-food by-products in European seabass (Dicentrarchus labrax) juvenilesPublication . Campos, I.; Matos, E.; Aragão, C.; Pintado, M.; Valente, L. M. P.Apparent digestibility coefficients (ADCs) of processed agro-food by-products were assessed in European seabass Dicentrarchus labrax). Each experimental diet was obtained by replacing 300 g/kg of a commercial-based diet used as reference (REF) with a test ingredient: wheat germ (GERM), okara meal (OKA), poultry by-product meal (POULT), steam hydrolysed (FeHY) and enzyme-treated feather meal (FeENZ), beta-lactoglobulin (β-Lg) and peptide fractions >3,000 Da obtained from brewer’s yeast (YeastP) and fish by-products (FishP). Dry matter ADC was highest in β-Lg (95%) and lowest in OKA (40%). Protein ADCs were high in β-Lg, FishP, GERM and POULT (>93%); intermediate in FeHY and FeENZ (85%–88%); and moderate in OKA and YeastP (70%–78%). The essential amino acids’ ADC mean was above 91% in POULT, β-Lg, GERM and FishP, 84%–89% in FeHY and FeENZ and 73%–76% in YeastP and OKA. Energy ADC was highest in POULT and β-Lg (89%–95%) and lowest in YeastP and OKA (61%–64%). Lipid ADC was highest for POULT and GERM (100%). Phosphorus ADC was lowest in GERM (19%) and highest in β-Lg (88%). FeHY, FeENZ, POULT, GERM, FishP and β-Lg are highlighted as protein sources for European seabass.
- C-ERB-2, P53, Ki67 proteins and receptors of estrogen and progesterone on the prognosis of epithelial ovarian cancerPublication . Tomé, A.; Leal, I.; Palmeiras, C.; Matos, E.; Amado, J.; Abreu, M.; Lopes, C.Ovarian cancer is the seventh most common cancer diagnosed in women worldwide. To date, many studies in epithelial ovarian cancer (EOC) have reported on the association HER-2/neu, p53 proteins and steroid hormones and their respective receptors with prognosis and/or the carcinogenesis process, but no definitive conclusion has been reached. Objectives: To assess the proteins c-erbB-2, p53, Ki67 and receptors of estrogen (ER) and progesterone (PR) of EOC, with regard to clinical stage findings and its effect on survival. Methods: 125 patients with a diagnosis of EOC treated by primary surgery and chemotherapy have participated. A surgical stage was noted and analyzed the correlation with c-erbB-2, p53, Ki67, ER and PR. Immunohistochemical analysis, using the anti-c-erbB-2, p53, Ki67 monoclonal antibodies, the antibody cod PR clone PgR and code ER-6-F11 Anti human estrogen. The c-erbB-2 study was complemented by genetic amplification and was reported univariate and multivariate analysis. Results: Age 55.7 ± 16; 50.2% with residual disease (< 2 cm); initial (54.6%) and advanced (45.4%) stage. Univariate analysis showed positive staining for c-erbB-2, p-53, Ki67, PR and ER. The patients with negative receptors had a significantly shortened survival time (p = 0.01) than patients with positive receptors. Multivariable analysis revealed only clinical FIGO stage as an independent prognostic of overall survival (p = 0.002). Other variables like c-erbB-2, p53, Ki67, and ER were not significantly related to survival. Conclusions: We concluded that patients with negative PR had a significantly shortened survival time than patients with positive receptors. The overexpression of markers c-erbB-2, p53, Ki67, and ER, were not significantly related to survival in EOC. Only the FIGO stage was achieved to be an independent predictor of overall survival. They should be evaluated together with the patient’s clinical status and other prognostic factors.
