Rev. Paul. Pediatr. (Ed. Port., Online); 39 (), 2021

ABSTRACT Objective: To evaluate the effect of pasteurization on antioxidant and oxidant properties of human milk. Methods: 42 samples of milk before and after pasteurisation were used to evaluate the antioxidant activity by the ferric reducing capacity and by scavenging the 2,2'-azino-bis 3-ethylbenz...

Guatura, Sandra Baltazar; Martinez, José Antônio Baddini; Bueno, Patricia Cincotto dos Santos; Santos, Manuel Lopes dos.

Säo Paulo med. j; 118 (4), 2000

CONTEXT: Increased hydrogen peroxide has been described in the expired breath condensate (H2O2-E) of several lung conditions, such as acute respiratory distress syndrome, chronic obstructive pulmonary disease and asthma. This technique has been advocated as being a simple method for documenting airway in...
