MOTIVATION Receptor-ligand interactions are a central phenomenon in most biological systems. They are characterized by molecular recognition, a complex process mainly driven by physicochemical and structural properties of both receptor and ligand. Understanding and predicting these interactions are major steps towards protein ligand prediction, target(More)
Antidepressants have been considered by their analgesic activity in numerous studies, and specifically tricyclic antidepressants to possess the greatest efficacy. Imipramine and doxepin have been reported to exhibit local anaesthetic properties. In order to investigate their cutaneous analgesic effect after topical application a nanoemulsion vehicle was(More)
Analyses of 16S rDNA genes were used to identify the microbiota isolated from the mucus of the zoanthid Palythoa caribaeorum at Porto de Galinhas on the coast of Pernambuco State, Brazil. This study is important as the first report of this association, because of the potential biotechnological applications of the bacterium Alcanivorax dieselolei, and as(More)
The exponents method for calculating the concentrations of species in multimetal-multiligand systems is introduced. This method uses the NewtonRaphson method with restricted step iteration, which guarantees a monotonically decreasing objective function. Variable transformation and scaling are performed to avoid underflows and overflows during the(More)
