Non-monotonic behavior of weak-polyelectrolytes adsorption on a cationic surface: A Monte Carlo simulation study
(Elsevier, 2021-01)
In this work, the weak polyelectrolyte (PE) adsorption on a strong cationic surface is studied with constant pH Monte Carlo simulations using a coarse-grained model. When a large number of PE chains is added to the system, ...
Panax ginseng metabolite (GIM-1) modulates the effects of monobutyl phthalate (MBP) on the GPR30/GPER1 canonical pathway in human Sertoli cells
(2020-09-01)
This study was performed to evaluate the effect of monobutyl phthalate (MBP) on GPR30-activated pathways in Sertoli cells. Additionally, we tested if GIM-1 (Panax ginseng metabolite) modulates MBP action. Human Sertoli ...
Protein Hydrolysis by Immobilized and Stabilized Trypsin
(Wiley-Blackwell, 2011-05-01)
The preparation of novel immobilized and stabilized derivatives of trypsin is reported here. The new derivatives preserved 80% of the initial catalytic activity toward synthetic substrates [benzoyl-arginine p-nitroanilide ...

Are nanoporous materials radiation resistant?
(American Chemical Society, 2011-06-09)
The key to perfect radiation endurance is perfect recovery. Since surfaces are perfect sinks for defects, a porous material with a high surface to volume ratio has the potential to be extremely radiation tolerant, provided ...
Regulation of Na(+)/H(+) exchanger NHE3 by glucagon-like peptide 1 receptor agonist exendin-4 in renal proximal tubule cells
(AMER PHYSIOLOGICAL SOC, 2009)
Carraro-Lacroix LR, Malnic G, Girardi AC. Regulation of Na(+)/H(+) exchanger NHE3 by glucagon-like peptide 1 receptor agonist exendin-4 in renal proximal tubule cells. Am J Physiol Renal Physiol 297: F1647-F1655, 2009. ...
Nova metodologia de estimativa de exposição ocupacional em radiologia intervencionista
(Universidade Estadual Paulista (Unesp), 2022-03-29)
A Radiologia Intervencionista é uma área da medicina que utiliza radiação ionizante como guia de intervenções. Os valores de dose aos quais os intervencionistas são expostos são difíceis de padronizar. Nesta pesquisa é ...
Modelagem computacional da hidrólise e do potencial redox de aquacomplexos de íons Ce³⁺, Ce⁴⁺, Eu²⁺ e Eu³⁺
(Universidade Federal de PernambucoUFPEBrasilPrograma de Pos Graduacao em Ciencia de Materiais, 2019)
The effect of the pH on the interaction of L-arginine with colloidal silver nanoparticles. A Raman and SERS study
(John Wiley & Sons, 2013)
Raman and surface enhanced Raman scattering (SERS) spectroscopies were used to study the pH effect (7 to 9) on the
interaction of arginine (Arg) with colloidal Ag nanoparticles (AgNps). A new methodology was implemented ...
Activation of Adenylyl Cyclase Causes Stimulation of Adenosine Receptors
(Karger, 2018-05)
AbstractBACKGROUND/AIMS:Signaling of Gs protein-coupled receptors (GsPCRs) is accomplished by stimulation of adenylyl cyclase, causing an increase of the intracellular cAMP concentration, activation of the intracellular ...
