Complexation between oleanolic and maslinic acids with native and modified cyclodextrins [PDF]

open access: yes, 2018
Oleanolic (OA) and maslinic (MA) acids are two natural triterpenoids with a wide range of beneficial effects for human health. However, their low solubility and permeability make their application in the food or industry difficult. The complexation of OA

Symurban Nanocrystals for Advanced Anti-Pollution Skincare [PDF]

open access: yes, 2020
Several of most common dermatoses worldwide, e.g., psoriasis and atopic dermatitis, are worsened in their clinical picture when the skin is regularly exposed to an increased air pollution level, e.g., particulate matter.

Solubility of Bilirubin in Aqueous Solutions.

open access: yesExperimental Biology and Medicine, 1962
SummarySolubility of unconjugated bilirubin was studied in protein-free aqueous solutions of various molarity and pH. At salt concentrations approximating that of extracellular fluid, bilirubin was found to be more soluble than has hitherto been assumed. Solubility of bilirubin in aqueous solution depends critically on pH and ionic strength.

Selection of elastomeric membranes for the removal of volatile organics from water [PDF]

open access: yes, 1993
A wide range of homogeneous elastomeric membranes has been prepared using dicumylperoxide as a general cross-linking agent. The membranes have been used for both equilibrium sorption measurements and steady-state pervaporation experiments to study ...

Silymarin-laden PVP-PEG polymeric composite for enhanced aqueous solubility and dissolution rate: Preparation and in vitro characterization

open access: yesJournal of Pharmaceutical Analysis, 2019
The aim of this work was to develop, optimize and characterize a silymarin-laden polyvinylpyrrolidone (PVP)-polyethylene glycol (PEG) polymeric composite to resolve low aqueous solubility and dissolution rate problem of the drug.

Changes in dissolved iron deposition to the oceans driven by human activity: a 3-D global modelling study [PDF]

open access: yes, 2015
The global atmospheric iron (Fe) cycle is parameterized in the global 3-D chemical transport model TM4-ECPL to simulate the proton- and the organic ligand-promoted mineral-Fe dissolution as well as the aqueous-phase photochemical reactions between the ...

Rhenium solubility and speciation in aqueous fluids at high temperature and pressure

open access: yesProgress in Earth and Planetary Science, 2023
In order to characterize rhenium transport via infiltration of fluids in the Earth's interior, the solubility and solution mechanisms of ReO2 in aqueous fluids were determined to 900 °C and about 1710 MPa by using an externally–heated hydrothermal ...

Effect of Oil Type on Spatial Partition of Resveratrol in the Aqueous Phase, the Protein Interface and the Oil Phase of O/W Emulsions Stabilized by Whey Protein and Caseinate

open access: yesAntioxidants, 2023
Oil-in-water emulsions contain the inner oil phase, the protein membrane at the interface and the aqueous phase. In this study, the spatial partition of resveratrol was investigated in sunflower oil, fish oil, medium-chain triglyceride (MCT) and ...

Hydrocarbon molar water solubility predicts NMDA vs. GABAA receptor modulation. [PDF]

open access: yes, 2014
BackgroundMany anesthetics modulate 3-transmembrane (such as NMDA) and 4-transmembrane (such as GABAA) receptors. Clinical and experimental anesthetics exhibiting receptor family specificity often have low water solubility. We hypothesized that the molar

Pharmaceutical particle technologies: An approach to improve drug solubility, dissolution and bioavailability

open access: yesAsian Journal of Pharmaceutical Sciences, 2014
Pharmaceutical particle technology is employed to improve poor aqueous solubility of drug compounds that limits in vivo bioavailability owing to their low dissolution rate in the gastrointestinal fluids following oral administration.
