“To compare precut and surgeon-cut organ cultured donor corneas for DSAEK. A total of 119 consecutive eyes treated with DSAEK were retrospectically identified. 65 grafts were cut by the surgeon (Moria, ALTK System) prior to DSAEK and 54 grafts were precut by laboratory technicians from the Danish Eye Bank (Horizon single-use system). 1 year after surgery, tomographic images were obtained with the Pentacam HR. Endothelial cell density (ECD) and best-corrected

visual acuity (BCVA) was determined. Graft thickness and graft asymmetry was evaluated in the centre and 1 mm from the Selleckchem Bafilomycin A1 edge of the graft in 6 semi-meridians. 1 year after surgery, the ECD loss was similar in the two groups, averaging 25.9 +/- A 14 % in surgeon-cut, and 22.9 +/- A 17 % in precut group (p = 0.33). Mean central graft thickness

was 172 +/- A 6 C59 wnt mu m in surgeon-cut grafts and 182 +/- A 6 mu m in precut grafts (p = 0.30). BCVA was similar in surgeon-cut and precut corneas; being 0.25 +/- A 0.02 logMAR and 0.24 +/- A 0.02 logMAR, respectively (p = 0.59). The graft asymmetry index was 1.48 +/- A 0.02 for surgeon-cut and 1.44 +/- A 0.02 for precut grafts. There were no significant differences in complications rate in both groups. No correlations between BCVA and central graft thickness or graft asymmetry index in both groups were observed. Organ cultured precut donor corneas are comparable with surgeon-cut grafts with respect to ECD, graft thickness and asymmetry, and postoperative complication rate.”
“To achieve enhanced gene transfection efficiency with ocular eye-drop therapy, a cationic core shell liponanoparticle Batimastat clinical trial (DLCS-NP) was designed by enveloping the plasmid-laden chitosan nanoparticle (CS-NP) into a cationic lipid shell. The cellular uptake of DLCS-NP was up to 1.25-fold and 5-fold higher than that of CS-NP and lipid-coated chitosan nanoparticles (LCS-NP), respectively. Further endocytosis

inhibition investigation discovered that facilitated by the cationic outer lipid layer, several other distinct pathways (besides clathrin-mediated endocytosis) were involved in the endocytosis of DLCS-NP. Endolysosome trafficking experiment verified that cationic lipid coating could facilitate the endolysosome escape of DLCS-NP. Consequently, using enhanced green fluorescence protein (EGFP) as a reporter gene, DLCS-NP-treated human conjunctival epithelial cells exhibited 3.1- and 3.5-fold more intense EGFP expression than that of LCS-NP and CS-NP, respectively. Finally, in vivo transfection experiments on rabbits revealed that EGFP expression exhibited 2.52-fold increase in DLCS-NP group than that of CS-NP group.
