Sentence examples for during the release test from inspiring English sources
The matrix tablets were prepared by direct compression of mixtures of drug and nanoparticles, and then the release properties, swelling properties and changes in molecular weight of PLGA during the release test were evaluated.
mathrm{Drug} mathrm{release} left(%right)=left {D}_i-{D}_tright)/{D}_itimes 100 (2)where D t is the concentration of DOX or ERL remaining in the nanoliposomes at a given time during the release test period and D i is the concentration of DOX or ERL encapsulated in the nanoliposomes before the drug release experiment.
A different ability to form a hydrated gel layer around the matrix tablets was visually observed during the release test.
The amorphous PAC, as demonstrated during the in vitro release test, provided a higher concentration of dissolved PAC in the surrounding lung fluid compared with the crystalline PAC powder and was immediately absorbed due to its good cell membrane permeability.
Synchrotron radiation X-ray computed microtomography (SR-μCT) was used to investigate the fine structural architectures of microspheres non-destructively at different sampling times during drug release test, which were simultaneously determined to quantitatively correlate the structural data with drug release behaviors.
The stability of sCT during production and release test after 24 h was studied by SDS-PAGE test.
For evaluation the stability of sCT in optimized formulation during production and release test after 24 h SDS-page or gel electrophoresis method using precast gradient gels (20% Tris-HCl/glycine, Bio-Rad, USA) was used which separates proteins based on their molecular weight range.
Tablet dimensions, viscoelastic properties, glass to rubber transition temperature (Tg), PLGA degradation rate and water uptake were analyzed in the freshly prepared implantable tablets as well as at several times during release test in phosphate buffer pH 7.4.
These results suggest that during the initial period of release test, much more amounts of ERL were released from the liposomes than those of DOX and there was a time-differential release between ERL and DOX.
We had first demonstrated that the native human insulin and the insulin released from nanovesicles upon 400 mg/dL glucose exposure showed similar bioactivity profiles after administration into diabetic mice at an equivalent dose, suggesting that the bioactivity of insulin was highly retained during the formulation preparation and release test.
The zero-order model did not fit the in vitro release data since the calcium-alginate/polymer mix beads were found to slowly and gradually undergo erosion during the in vitro release testing.
