Studies on Surfactants, Cosurfactants, and Oils for Prospective Use in Formulation of Ketorolac Tromethamine Ophthalmic Nanoemulsions

Pharmaceutics, 2021
Nanoemulsions (NE) are isotropic, dispersions of oil, water, surfactant(s) and cosurfactant(s). A range of components (11 surfactants, nine cosurfactants, and five oils) were investigated as potential excipients for preparation of ketorolac tromethamine (

THE ACTIVATION OF PURIFIED HUMAN PLASMINOGEN IN SOLUTIONS OF ETHYLENE GLYCOLS

, 1963
Ethylene glycols have been found to allow activation of purified preparations of human plasminogen. The activity of the enzyme formed, plasmin, was measured using TAMe (p-toluene-sulphonyl-L-arginine methyl ester) as a substrate.

Controlling the positive ion electrospray ionization of poly(ethylene glycols) when using ultra-high-performance supercritical fluid chromatography-mass spectrometry

, 2023
Poly(ethylene glycols) are complex polymers often added to pharmaceutical formulations to improve drug solubility and delivery. One of the main challenges when using chromatographic techniques coupled to mass spectrometry is the unselective ionization of

Kinematic viscosities of poly(ethylene glycols)

, 2015
Kinematic viscosities data have been obtained as a function of temperature for poly(ethylene glycols) with different molecular weights. The viscosity measurements were performed at ambient pressure and several temperatures ranging from 293.15 (or above ...

Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

Molecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...
