To investigate the feasibility and advantages of using perfluorocarbon liquid (PCL) perfusion to remove vitreous during suction-cutting vitrectomy in rabbit and pig eyes.
This system comprises secretory and ciliated cells, a periciliary liquid (PCL) layer where the cilia move to impulse the mucus, and the propelled overlaying mucus [ 18].
The differentiated cell cultures were incubated at 21% or 1% O2 for 72 h, after which the cell medium was collected, and the apical surfaces were rinsed to collect the periciliary liquid (PCL) including secreted proteins and peptides.
In the LNC-PCL formulations, the liquid portion was 160 μL/10 mL of suspension corresponding to approximately 1.52 mg of fluorescent product per mL of suspension, while in NC-RS100 and in NC-S100, the liquid portion was 333 μL/10 mL of suspension corresponding to approximately 3.15 mg of fluorescent product per mL of suspension.
However, our OCT system axial resolution of ~3 µm is, in most cases, sufficient to resolve the PCL within the airway surface liquid [ 34], while our transverse spot size of ~12 µm covers ~12 hBE cells and ~2000 individual cilia.
Given these results, these two types of bioplastic (starch and PCL films) were chosen for the liquid culture method.
Nanoscale confinement of normally semi-crystalline PCL within blends with 100 nm dispersed phases impedes PCL crystallizability, yielding liquid-state PCL domains at room temperature and demonstrating that properties of nanostructured blends and microstructured blends can differ greatly.
To quantify PCL-degrading activity, 1 ml of an overnight liquid culture in UF medium was mixed with 20 ml of basal medium containing 0.3% PCL and incubated at 30-50°C 30-50°Ch.
This is possibly due to overlying mucus motion changing the light beam refraction at the air-liquid interface, mucus scattering within the PCL, or creep in the system causing phase instability on this 100−200 ms time scale.
Furthermore, at higher temperature, the resulting immobilized PPL (IPPL) could successfully perform the syntheses of polycaprolactone (PCL) and poly 5,5-dimethyl-1,3-dioxan-2-one) (poly 5,5-dimethyl-1,3-dioxan-2-one
