1. Development and Validation of a Rapid and Reliable HPLC-FLD Method for the Quantification of Ciprofloxacin and Enrofloxacin Residues in Zea mays
The accumulation of antibiotics by plants is a currently concern associated to yield reduction and transference of antibiotic residues along the food web. Maize is a staple food in many parts of the world; it is also considered an important ingredient in animal nutrition. Considering the lack of validated analytical methods for the analysis of ciprofloxacin

9. The role of NMDA receptor antagonists, amantadine and memantine, in schizophrenia treatment: a systematic review
Abstract Objective Schizophrenia is a complex and chronic psychiatric disorder. In recent years, studies have found glutamatergic system participation in its etiopathogenesis, especially through aberrant NMDA receptors functioning. Thus, drugs that modulate this activity, as amantadine and memantine, could theoretically be used in its treatment. To perform

10. Development of a generic method for the determination of proton-pump inhibitors by capillary zoneelectrophoresis
A generic capillary zone electrophoresis method was developed for the analysis of four proton pump inhibitors: omeprazole, pantoprazole, lansoprazole and rabeprazole. During preliminary analysis screening of phosphate buffers at different pH levels was performed, in order to determine the optimum pH domain suitable for the simultaneous determination of all s
