ABSTRACT Background: The prison system in Paraná, Brazil, is experiencing serious problems related to the increasing number of prisoners. Control of hepatitis C virus (HCV) has become more intense because the incarcerated population is considered a high-risk group for contagious diseases due to the favorable conditions found in prisons for the spread of these morbidities. The objective of this study was to identify features associated with hepatitis C infection among male prisoners in correctional institutions of Paraná state, Brazil.

Fumonisin B1 and ochratoxin A in beers made in Brazil Ciênc. Tecnol. Aliment.
Kawashima,Luciane Mie; Vieira,Ana Paula; Soares,Lucia Maria Valente.
Samples of beer made in Brazil were analyzed for the presence of fumonisin B1 (FB1) and ochratoxin A (OTA). FB1 was searched for in 58 beer samples from 30 plants located in nine states. The samples were concentrated and cleaned up with strong ion exchange column, derivatized with OPA and analyzed by HPLC with fluorescence detection. The limit of detection was 0.26 ng.mL-1 and the average recovery was 98%. Twenty-five samples contained FB1 ranging from 1 to 40 ng.mL-1. Beer (123 samples) from 36 plants located in 5 states were analyzed for OTA by means of immunoaffinity column cleanup followed by liquid chromatography associated with fluorescence. The detection limit was 0.1 ng.mL-1 and the average recovery was 92%. Five samples contained OTA in...
