Development and evaluation of novel nanophotosensitizers as photoantimicrobial agents against Staphylococcus aureus
(Elsevier Science, 2019-01-01)
The main aim of the present study was to synthetize polyacrylamide nanoparticles and to use them as photosensitizer carriers. The new monobrominated derivatives (monobrominated neutral red and monobrominated azure B) were ...
Casein glycomacropeptide pH-driven self-assembly and gelation upon heating
(Elsevier, 2011-07)
Casein glycomacropeptide (CMP) found in cheese whey is a C-terminal hydrophilic glycopeptide released from κ-casein by the action of chymosin during cheese making. In a previous work a self-assembly model for CMP at room ...
Polyphosphate Poly(amine) Nanoparticles: Self-Assembly, Thermodynamics, and Stability Studies
(American Chemical Society, 2019-11)
The interaction of polyamine poly(allylamine hydrochloride) with Na3PO4, Na4P2O7, Na5P3O10, Na6P6O18, and (NaPO3)26 salts and the formation of polyamine phosphate nanoparticles (PANs) are studied here. Dynamic light ...
Hydroxypropylmethylcellulose at the oil-water interface. Part I. Bulk behaviour and dynamic adsorption as affected by pH
(Elsevier, 2011-01)
The bulk and oil-water (O/W) surface behaviour of four different commercial types of hydroxypropylmethylcelluloses (HPMCs) was studied at pH3 and 6.Dynamic light scattering (DLS) analysis of particle size distribution in ...
Physicochemical and biological characterization of RTXM83, a new Rituximab biosimilar
(Springer, 2019-03)
BACKGROUND: RTXM83 is a rituximab biosimilar with proven clinical safety and efficacy. It is the first rituximab biosimilar developed and approved in South America and is currently marketed in several Latin American, Middle ...
Understanding metallic nanoparticles stabilization in water by imidazolium salts: A complete physicochemical study
(Wiley Blackwell Publishing, Inc, 2020-09)
We present the total characterization (by UV-Vis spectroscopy, Transmission Electron Microscopy, Dynamic Light Scattering, Zeta potential, Fourier Transform Infrared Spectroscopy, and Nuclear Magnetic Resonance) of silver ...
Influence of the AOT counterion chemical structure in the generation of organized systems
(American Chemical Society, 2020-09-22)
The impact of the imidazolium counterion structure on the organized systems formed by the surfactant 1,4-bis-2-ethylhexylsulfosuccinate, AOT, both in aqueous solutions and in nonpolar solvents is investigated. With this ...
A protic ionic liquid, when entrapped in cationic reverse micelles, can be used as a suitable solvent for a bimolecular nucleophilic substitution reaction
(Royal Society of Chemistry, 2016-02)
In this work, we have explored how the confinement of the protic ionic liquid (IL) ethylammonium nitrate (EAN) inside toluene/benzyl-n-hexadecyldimethylammonium chloride (BHDC) reverse micelles (RMs) affects the Cl- ...
Mitochondrial KATP channels participate in the limitation of infarct size by cariporide
(Springer, 2011-05)
The objective of this study is to assess the participation of mitochondrial ATP-sensitive potassium (mitoK(ATP)) channels in the cardioprotective effects of the Na(+)/H(+) exchanger (NHE-1) blocker cariporide in ...
Whey proteins-folic acid complexes: Formation, isolation and bioavailability in a Lactobacillus casei model
(Elsevier, 2020-10)
The objective of this work was to explore the complexation of a whey protein (β-lactoglobulin, β-lg) and a whey protein isolate (WPI) with folic acid (FA) at pH 3.0. Complexes were formed through non-covalent interactions, ...
