Bacterial endogenous endophthalmitis.
Valle, Luisa; Camba, M; Fernández, F; Paz, J; Sanjurjo, A; De La Fuente Aguado, JavierEndogenous bacterial endophthalmitis is an uncommon disease, secondary to hematogenous spread of a septic focus. Despite advances in diagnostic and therapeutic methods, it remains a potential cause of blindness. We report a case of a diabetic patient with endogenous endophthalmitis of the right eye secondary to an Escherichia coli bacteremia of urinary origin. The evolution was torpid, with loss of visual acuit...
Biological parameters of larvae, nymphs, and engorged females of Amblyomma caje...
Freitas,C.M.V.; Leite,R.C.; Oliveira,P.R.; Fernández,F.C.The development of acquired resistance to Amblyomma cajennense ticks was evaluated. A total of 18 rabbits were uniformly distributed into three groups named GL, GN, and GA that were submitted to three consecutive infestations with, respectively, larvae, nymphs, and adults of A. cajennense. After the infestations, the parasitic and reproductive parameters of recovered instars were evaluated. A significant reduct...
SnO2 extended gate field-effect transistor as pH sensor
Batista,P. D.; Mulato,M.; Graeff,C. F. de O.; Fernandez,F. J. R.; Marques,F. das C.Extended gate field-effect transistor (EGFET) is a device composed of a conventional ion-sensitive electrode and a MOSFET device, which can be applied to the measurement of ion content in a solution. This structure has a lot of advantages as compared to the Ion- Sensitive Field Effect Transistor (ISFET). In this work, we constructed an EGFET by connecting the sensing structure fabricated with SnO2 to a commerci...
Avaliação do estado nutricional do feijoeiro (Phaseolus vulgaris L.) cultivado ...
Camacho,R; Calvache,A.M.; Falcão,N.; Fernandez,F.; Demattê,J.A.M.; Malavolta,E.O feijoeiro (Phaseolus vulgaris L. cv. Carioca) foi cultivado em solução nutritiva na presença das seguintes concentrações de N, P e K, respectivamente em milimoles por litro: 16-2-6; 4-2-6; 1,6-2-6; 16-0,5-6; 16-0-6; 16-2-3; 16-2-0,6. Os outros macronutrientes e os micronutrientes foram fornecidos em doses iguais a todas as plantas. O estado nutricional foi avaliado através das seguintes técnicas: diagnose fol...
