Hydroxyapatite-based materials of marine origin: a bioactivity and sintering study
Piccirillo, C.; Pullar, R. C.; Costa, E.; Santos-Silva, A.; Pintado, Manuela; Castro, Paula M. L.Single phase hydroxyapatite (HAp) and biphasic material hydroxyapatite/beta-tricalcium phosphate (HAp/beta-TCP) were obtained from a marine source (Atlantic cod fish bones). Here we report a study on the biological properties of these materials, including cytotoxicity, bioactivity and haemocompatibility. Results showed that the materials are not cytotoxic, neither in their powder nor in pellet form; indeed grow...
Bilirubin is independently associated with oxidized LDL levels in young obese p...
Nascimento, H.; Alves, A.; Coimbra, S.; Catarino, C.; Gomes, D.; Bronze-da-Rocha, E.; Costa, E.; Rocha-Pereira, P.; Aires, L.; Mota, J.; Mansilha, H.BACKGROUND: Bilirubin can prevent lipid oxidation in vitro, but the association in vivo with oxidized low-density lipoprotein (Ox-LDL) levels has been poorly explored. Our aim is to the association of Ox-LDL with total bilirubin (TB) levels and with variables related with metabolic syndrome and inflammation, in young obese individuals. FINDINGS: 125 obese patients (13.4 years; 53.6% females) were studied. TB, l...
Effect of Aging in the Perception of Health-Related Quality of Life in End-Stag...
Moura, A.; Madureira, J.; Alija, P.; Fernandes, J.; Oliveira, .; Lopez, M.; Filgueiras, M.; Amado, L.; Sameiro-Faria, M.; Miranda, V.; Santos-Silva, A.This work aimed to evaluate how aging could influence patients' perception of health quality of life (HRQOL), as well as, the effect of aging on dialysis adequacy and in hematological, iron status, inflammatory and nutritional markers. In this transversal study were enrolled 305 ESRD patients under online-hemodiafiltration (OL-HDF) (59.67% males; 64.9 ± 14.3 years old). Data about comorbidities, hematological d...
Comparison between CDC and WHO BMI z-score and their relation with metabolic ri...
Nascimento, H; Catarino, C; Mendonça, D; Oliveira, P; Alves, A; Medeiros, A; Rocha-Pereira, P; Rêgo, C; Mansilha, H; Aires, L.; Mota, J.Growth-curves are an important tool for evaluating the anthropometric development in pediatrics. The different growth-curves available are based in different populations, what leads to different cut-offs. Pediatric obesity tracks into adulthood and is associated with increased cardiovascular risk. The accurate assessment of a child nutritional status using growth-curves can indicate individuals that are either ...

Therapeutic strategies for pediatric obesity and their effect in cardiovascular...
Nascimento, H.; Quintanilha, A.; Santos-Silva, A.; Belo, L.Pediatric obesity is an important public health problem nowadays. Portugal is no exception, being one third of children and adolescent either overweight or obese. The behavioral approach is the basilar stone of obese treatment nowadays. It focuses in change lifestyle, substituting unhealthy habits by new, healthier, ones.A great number of strategies have been studied to try to respond to this growing problem, w...
Iron as the key modulator of hepcidin expression in erythroid antibody-mediated...
Fernandes, J. C.; Garrido, P.; Ribeiro, S.; Rocha-Pereira, P.; Bronze-da-Rocha, E.; Belo, L.; Costa, E.; Reis, F.; Santos-Silva, A.Erythroid hypoplasia (EH) is a rare complication associated with recombinant human erythropoietin (rHuEPO) therapies, due to development of anti-rHuEPO antibodies; however, the underlying mechanisms remain poorly clarified. Our aim was to manage a rat model of antibody-mediated EH induced by rHuEPO and study the impact on iron metabolism and erythropoiesis. Wistar rats treated during 9 weeks with a high rHuEPO ...

Potential cardiovascular risk protection of bilirubin in end-stage renal diseas...
Sameiro-Faria, M.; Kohlova, M.; Ribeiro, S.; Rocha-Pereira, P.; Teixeira, L.; Nascimento, H.; Reis, F.; Miranda, V.; Bronze-da-Rocha, E.We evaluated the potential cardiovascular risk protection of bilirubin in hemodialysis (HD) patients. An enlarged set of studies were evaluated in 191 HD patients, including hematological study, lipid profile, iron metabolism, nutritional, inflammatory markers, and dialysis adequacy. The TA duplication screening in the UDP-glucuronosyltransferase 1 A1 (UGT1A1) promoter region was also performed. The UGT1A1 geno...
