Application of bar adsorptive microextraction for the determination of levels o...
Oliveira, Mariana N.; Gonçalves, Oriana C.; Ahmad, Samir M.; Schneider, Jaderson K.; Krause, Laiza C.; Neng, Nuno R.; Caramão, Elina B.This work entailed the development, optimization, validation, and application of a novel analytical approach, using the bar adsorptive microextraction technique (BAμE), for the determination of the six most common tricyclic antidepressants (TCAs; amitriptyline, mianserin, trimipramine, imipramine, mirtazapine and dosulepin) in urine matrices. To achieve this goal, we employed, for the first time, new generation...
Volatile nitrogenous compounds from bacteria: source of novel bioactive compounds
Valença, Camilla A. S.; Barbosa, Ana A. T.; Souto, Eliana B.; Caramão, Elina B.; Jain, SonaBacteria can produce nitrogenous compounds via both primary and secondary metabolic processes. Many bacterial volatile nitrogenous compounds produced during the secondary metabolism have been identified and reported for their antioxidant, antibacterial, antifungal, algicidal and antitumor activities. The production of these nitrogenous compounds depends on several factors, including the composition of culture m...
