Correlation between preoperative aqueous cytokine levels and mid-term corneal endothelial cell loss following penetrating keratoplasty.

Objective: To investigate the association between preoperative aqueous humour (AqH) cytokines and mid-term endothelial cell density (ECD) following penetrating keratoplasty (PKP).

Methods: This study analysed a total of 87 eyes of which 54 underwent PKP and 33 eyes underwent cataract surgery. AqH samples were collected at the beginning of surgery.

Image Analysis Characterizes Phenotypic Variation in the Growth of Mushroom-Forming Fungus Schizophyllum commune.

Schizophyllum commune, a common wood-decay mushroom known for its extremely high genetic variation and as a rare cause of human respiratory diseases, could be a promising model fungus contributing to both biology and medicine. To better understand its phenotypic variation, we developed an image analysis system that quantifies morphological and physiological traits of mycelial colonies in Petri dishes. This study evaluated growth of six wild and one clinical isolates of Japanese S.

Protrusion of KCNJ13 Gene Knockout Retinal Pigment Epithelium Due to Oxidative Stress-Induced Cell Death.

Purpose: This study was performed to elucidate the mechanisms of morphological abnormalities in a Leber congenital amaurosis 16 (LCA16) cell model using KCNJ13 knockout (KO) retinal pigment epithelial cells derived from human iPS cells (hiPSC-RPE).

Methods: In KCNJ13 KO and wild-type hiPSC-RPE cells, ZO-1 immunofluorescence was performed, and confocal images were captured. The area and perimeter of each cell were measured.

Graft Size and Double Scroll Formation Rate in Descemet Membrane Endothelial Keratoplasty.

Purpose: This study aimed to evaluate the usefulness of intentional double scroll formation of donor Descemet membrane (DM) inside a glass tube inserter (the Fogla technique) in DM endothelial keratoplasty (DMEK) for controlled insertion and unfolding of grafts.

Methods: Eleven consecutive patients who underwent DMEK were included in this study. We sought to specify graft characteristics in which double scroll configuration was successfully formed using the Fogla technique.
