Transplant glomerulopathy: clinico-pathologic features
Silva, C; Cotovio, P; Marques, M; Afonso, N; Sancho, MR; Carvalho, F; Trindade, H; Carreira, A; Campos, M; Nolasco, FTransplant glomerulopathy is a sign of chronic kidney allograft damage. It has a distinct morphology and is associated with poor allograft survival. We aimed to assess the prevalence and clinic-pathologic features of transplant glomerulopathy, as well as determine the functional and histological implications of its severity. We performed a single-centre retrospective observational study during an eight-year per...

Prognostic Factors in Adult Patients with Idiopathic IgA Nephropathy
Silva, C; Afonso, N; Cotovio, P; Marques, M; Carvalho, F; Carreira, AIntroduction. IgA nephropathy is the dominant primary glomerular disease found throughout the majority of the world’s developed countries. Accurately identifying patients who are at risk of progressive disease is challenging. We aimed to characterise clinical and histological features that predict poor prognosis in adults. Patients and Methods. We performed a single-centre retrospective observational study of b...
Sustained drug released from contact lens
Ferreira, J. A.; Oliveira, P. de; Silva, P. M. da; Carreira, A.; Gil, H.; Murta, J. N.This paper focuses on ophthalmic drug release from a loaded copolymer: the drug is dispersed in the polymeric matrix and entrapped in particles. The copolymer is based in 2-hydroxyethyl methacrylate co-methacrylic acid and silicone is used to prepare the loaded particles. A mathematical model to simulate the drug release is proposed and a qualitative analysis is performed. Experimental results are compared with...
Probing the SERCA1a sarcoplasmic reticulum Ca2+-ATPase phosphorylation-site mut...
Carreira,A.C.O.; Bastos,C.M.V.; Verjovski-Almeida,S.The expression of sarcoplasmic reticulum SERCA1a Ca2+-ATPase wild-type and D351E mutants was optimized in yeast under the control of a galactose promoter. Fully active wild-type enzyme was recovered in yeast microsomal membrane fractions in sufficient amounts to permit a rapid and practical assay of ATP hydrolysis and phosphoenzyme formation from ATP or Pi. Mutant and wild-type Ca2+-ATPase were assayed for phos...
