Purificação do ácido clavulânico por processo de filtração tangencial, extração por sistema de duas fases aquosas e re-extração com resina de troca iônica
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2010-06-09)
Clavulanic acid is a β-lactam substance with low antibiotic activity. Nonetheless, it is an important medicine which acts as a potent β-lactamase inhibitor. These enzymes catalyze the hydrolysis of β-lactam ...
Barium, Tea and Sodium Sensitive Potassium Channels are Present in the Human Placental Syncytiotrophoblast Apical Membrane
(W B SAUNDERS CO LTD, 2008-10)
The human placental syncytiotrophoblast (hSTB) is a polarized epithelial structure, without paracellular
routes, forming the main barrier for materno–fetal exchange. There is ample evidence suggesting the
presence of ...

Determination of mercury in river water by diffusive gradients in thin films using P81 membrane as binding layer
(Elsevier B.V., 2014-11-01)
In this work, a device based on diffusive gradients in thin films (DGT) was evaluated for the determination of Hg(II) in river water. The DGT device was assembled with a cellulose phosphate ion exchange membrane (P81 ...
