Effect of disinfectant solutions on a denture base acrylic resin.
(2012-12-01)
The aim of this study was to evaluate the hardness, roughness and mass loss of an acrylic denture base resin after in vitro exposure to four disinfectant solutions. Forty specimens (Clássico, Brazil) were prepared and ...
Dimensional alterations and solubility of new endodontic sealers
(2010-12-01)
This study evaluated the dimensional alterations and the solubility of two experimental endodontic sealers based on Copaifera multijuga oil-resin (Biosealer) and castor oil bean cement (Poliquil), maintained in different ...
Avaliação dos parâmetros de solubilidade de Hildebrand/Hansen na seleção de solventes para a extração de pesticidas organoclorados do solo
(Sociedade Brasileira de Química, 2011-09-01)
This work evaluated the use of the Hildebrand/Hansen solubility parameters for selection of solvents for extraction of the organochlorine pesticides pp' DDT, pp' DDE, Aldrin and a-Endossulfan from soil using columns packed ...
Cocristais: uma estratégia promissora na área farmacêutica
(Soc Brasileira Quimica, 2016)
Pharmaceutical cocrystals have emerged as a useful strategy to improve the aqueous solubility of poorly water soluble drugs by aiming to enhance their oral absorption and bioavailability. Aqueous cocrystal solubility can ...
Effect of sodium trimetaphosphate on hydroxyapatite solubility: An in vitro study
(2013-08-20)
This study evaluated the effect of different concentrations of sodium trimetaphosphate (TMP) with and without fluoride (F) on the concentration of calcium (Ca), phosphorus (P) and F in hydroxyapatite (HA). Synthetic HA ...
Solubility of proteins from quail (Coturnix coturnix japonica) egg white as affected by agitation time, pH, and salt concentration

Determination of solubility product of mercurous acetate at various ionic strengths in aqueous medium
(Editora Unesp, 1996-01-01)
The conditionals (K-ps) and thermodynamics (K-ps(o)) solubility products of mercurous acetate have been determined, in aqueous solution, at 25 degrees C and ionic strength (I) comprised between 0.300 and 3.000 mol/L (NaClO4). ...
Interaction between nitroheterocyclic compounds with beta-cyclodextrins: Phase solubility and HPLC studies
(Elsevier B.V., 2008-08-05)
Chagas disease is a serious health problem for Latin America. Nitrofurazone (NF) and Hidroxymethylnitrofurazone (NFOH) are active against Trypanosoma cruzi. The effect of beta-cyclodextrin (beta-CD) and dimethyl-beta-cyclodextrin ...
A new insight about pharmaceutical dosage forms for benzathine penicillin G
(2006-12-01)
In this work, a micellar system of benzathine penicillin G (BPG) in sodium deoxycholate (NaDC) was developed and evaluated physicochemically. The solubility profile of the drug in water and buffer solutions at various pH ...
Solubility origin at the nanoscale: enthalpic and entropic contributions in polar and nonpolar environments
(Royal Soc Chemistry, 2017)
Nanostructures are known to be poorly soluble, irrespective of their elemental composition, shape, electronic structure, dipole moment, hydrophobicity/hydrophilicity and the employed solvent. The methods of colloid chemistry ...
