(Asoc Quimicos, Inst Quimico Sarria, 2015)The photophysical behavior of 7-amino-3-phenyl-2H-benzo[b][1,4]oxazin-2-one was studied in organic solvents and in aqueous solutions of beta-cyclodextrin using steady-state fluorescence and computational chemistry methods. ...
-
(1989)1. The cardiovascular effects of CLX were studied. 2. CLX induced hypotension, bradycardia, negative chronotropism and negative inotropism. 3. Electrophysiological studies showed a decrease of sinus venosus discharge ...
-
(2010)To improve downstream processing, protein engineering can be used to modify particular properties of a protein, such as specific affinity, charge, or hydrophobicity. The most common modification involves the peptide tags ...
