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...
Karyological, biochemical, and physiological aspects of Callophysus macropterus...
Ramirez-Gil,H.; Feldberg,E.; Almeida-Val,V.M.F.; Val,A.L.Karyological characteristics, i.e., diploid number, chromosome morphology and nucleolus organizer regions (NORs), biochemical characteristics, i.e., electrophoretic analysis of blood hemoglobin and the tissue enzymes lactate dehydrogenase (LDH), malate dehydrogenase (MDH), alcohol dehydrogenase (ADH), and phosphoglucose isomerase (PGI), and physiological characteristics, i.e., relative concentration of hemoglob...
