The comparable behavior may be explained by the chemical properties of PVP-hypericin: in this formulation hypericin is not covalently bound to polyvinylpyrrolidone, but forms complexes consisting of two PVP- and one hypericin molecules [ 13].
Thus, considering the combined effect of chemical adsorption and steric effect, we can deduce the growth mechanism of silver nanocrystals with these four PVPs.
Four PVP-I antiseptic products were tested in this study.
This study investigated the in vitro efficacy of four PVP-I hand wash and hand rub products against EBOV.
Although the minimum contact time for hygienic hand rub and hand wash defined in EN14476:2013 [ 7] is 30 s, we investigated the four PVP-I products with a minimum contact time of 15 s.
Recently, two derivatives of PVP named PVP-A and PVP-E were synthesized by our group and PVP-A was verified to have good inhibition performance by experiments.
Coronary angioplasty was performed on swine using balloon catheters modified with two polyvinylpyrrolidone (PVP -based coatings of similar lubricity, but different levels of PVP -basedes (5-fold) when tested in a tortuous path model.
Five μM PVP-hypericin and relatively high light fluences (>2 J·cause cause 50% of cells to lose their metabolic activity, which is not the case for 50 μM AlPCS4.
Additionally, between the two BPMs, RPSu-PVP-based BPM took less time to attain maximum concentrations for both acid and base when compared to PSDVB-based BPM.
In this research, molecular dynamics simulation (MD) and experimental methods were applied to study the cohesive energy density, mechanical properties, bonding behavior, and surface morphology of three polymer binders (PVP, PAM, PVA) employed in the 3D fabrication of hydroxyapatite (HA) bone scaffolds.
