Circulating cell-free DNA levels in Portuguese patients with psoriasis vulgaris...
Coimbra, S; Catarino, C; Costa, E; Oliveira, H; Figueiredo, A; Rocha-Pereira, P; Santos-Silva, Aassociated with inflammation. OBJECTIVES: We aimed to understand the relation of CFD levels with psoriasis severity, defined by the Psoriasis Area and Severity Index (PASI), with inflammation and with psoriasis therapy. METHODS: Forty-six patients with psoriasis vulgaris were evaluated before (T0) and after 12 weeks (T12) of treatment with narrowband ultraviolet light B (NB-UVB; n = 17), psoralen plus UVA (PUVA...
Body Fat Percentage Is a Major Determinant of Total Bilirubin Independently of ...
Belo, L; Nascimento, H; Kohlova, M; Bronze-da-Rocha, E; Fernandes, J; Costa, E; Catarino, C; Aires, L; Mansilha, HF; Rocha-Pereira, P; Quintanilha, AOBJECTIVES: Bilirubin has potential antioxidant and anti-inflammatory properties. The UGT1A1*28 polymorphism (TA repeats in the promoter region) is a major determinant of bilirubin levels and recent evidence suggests that raised adiposity may also be a contributing factor. We aimed to study the interaction between UGT1A1 polymorphism, hematological and anthropometric variables with total bilirubin levels in you...
Chemopreventive Efficacy of Atorvastatin against Nitrosamine-Induced Rat Bladde...
Parada, B; Reis, F; Pinto, A; Sereno, J; Xavier-Cunha, M; Neto, P; Rocha-Pereira, P; Mota, A; Figueiredo, A; Teixeira, FTo investigate the anti-carcinogenic effects of Atorvastatin (Atorva) on a rat bladder carcinogenesis model with N-butyl-N-(4-hydroxibutil)nitrosamine (BBN), four male Wistar rat groups were studied: (1) Control: vehicle; (2) Atorva: 3 mg/kg bw/day; (3) Carcinogen: BBN (0.05%); (4) Preventive Atorva: 3 mg/kg bw/day Atorva + BBN. A two phase protocol was used, in which the drug and the carcinogen were given betw...
Hemorheological and cardiovascular effects of erythropoietin in a rat model of ...
Piloto, N.; Teixeira, HM; Garrido, P.; Teixeira-Lemos, E.; Teixeira, M.; Parada, B.; Sereno, J.; Pinto, R .; Alves, R.; Santos, P.; Romão, AM; Nunes, S.Recombinant human erythropoietin (rhEPO) has been therapeutically used for correction of anaemia. However, due to the increase in circulating red blood cells (RBCs) it promotes, thus increasing oxygen delivery to muscles and improving performance in sport, it has been also illegally used as sports doping. Besides the well known increase of hematocrit and blood viscosity; which might cause serious complications ...
Caracterização hemorreológica, bioquímica e cardiovascular num modelo de doença...
Garrido, P.; Costa, Elísio; Teixeira-Lemos, E.; Parada, B.; Teixeira, M.; Santos, P.; Piloto, N.; Sereno, J.; Alves, R.; Pinto, R.; Rocha-Pereira, P.Chronic kidney disease (CKD) is a major public health problem throughout the world. The major outcomes include a rapid progression, with development of anaemia and serious complications, namely thromboembol ic and cardiovascular events. The pathophysiological alterations depend on the CKD degree, which will also determine the moment to initiate hemodialysis and recombinant erythropoietin (rhEPO) therapies Thus,...
Hypertension induced by immunosuppressive drugs: a comparative analysis between...
Reis, F; Parada, B; Teixeira de Lemos, E; Garrido, P; Dias, A; Piloto, N; Baptista, S; Sereno, J; Eufrásio, P; Costa, E; Rocha-Pereira, PThe purpose of this study was to compare the effects of sirolimus (SRL) vs cyclosporine (CsA) concerning the cardiovascular mechanisms hypothetically contributing to hypertension development. Three rat groups were studied: control (vehicle), CsA (5 mg/kg/d), and SRL (1 mg/kg/d). The following parameters were evaluated after 7 weeks of treatment: blood pressured (BP) and heart rate (HR; tail cuff), lipid profile...
Recombinant human erythropoietin therapy has beneffical cardio-renal effects on...
Garrido, P.; Reis, F.; Costa, Elísio; Parada, B.; Piloto, N.; Sereno, J.; Teixeira, A.; Pinto, R.; Figueiredo, A.; Alves, R.; Rocha-Pereira, P.This study aimed to assess the cardio-renal effects of rhEPO therapy on an animal model of moderate chronic renal failure (CRF). Four groups (n =7) of male rat were evaluated during a 12-week follow up period: control; rhEPO: 50 IU/Kg/wk; CRF: two-stage 3/, nephrectomy; CRF+ rhEPO (start after the 3'd wk of surgery). Renal function, haematology and serum inflammation and redox status were assessed. rhEPO treatm...

Oxidative Stress in Cyclosporine-Induced Hypertension: Evidence of Beneficial E...
Reis, F.; Rocha-Pereira, P.; Lemos, E. Teixeira de; Parada, B.; Baptista, S.; Figueiredo, A.; Santos-Silva, A.; Costa-Almeida, C.; Mota, A.The aim of this study was to evaluate the effect of cyclosporine (CsA) on oxidative stress as well as the use of a nitric oxide (NO) donor, the organic nitrate isosorbide-5-mononitrate (Is-5-Mn), to prevent or reverse CsA-induced toxicity, namely on the vascular NO-cGMP pathway or on oxidative equilibrium. The following rat groups (n = 8) were tested: (1) a control group; (2) the CsA group (5 mg/kg/d for 7 week...
Dual Effect of Nitrate Therapy for Cyclosporine-Induced Hypertension on Vascula...
Reis, F.; Lemos, E. Teixeira de; Almeida, L.; Parada, B.; Garrido, A. P.; Rocha-Pereira, P.; Santos-Silva, A.; Santos-Dias, J.; Dinis, A.The present study sought to evaluate the prevention and reversion effects of isosorbide-5-mononitrate (Is-5-Mn) on the development of hypertension (HT) and on the underlying vascular and platelet morphofunctional disturbances, using an animal model of cyclosporine (CsA)-induced HT. The following rat groups (n = 8) were tested: (1) a control group (orange juice, for 7 weeks); (2) the CsA group (5 mg/kg/d for 7 w...
