The present study was designed to evaluate the effects of human amniotic fluid (HAF) on the growth of human corneal endothelial cells (HCECs) and to establish an in vitro method for expanding HCECs. HCECs were cultured in DMEM-F12 supplemented with 20% fetal bovine serum (FBS). Confluent monolayer cultures were trypsinized and passaged using either FBS- or… (More)
We say that two graphs G 1 and G 2 with the same vertex set commute if their adjacency matrices commute. In this paper, we find all integers n such that the complete bipartite graph K n, n is decomposable into commuting perfect matchings or commuting Hamilton cycles. We show that there are at most n−1 linearly independent commuting adjacency matrices of… (More)
In this paper, we investigate connected nonregular graphs with four distinct Laplacian eigen-values. We characterize all such graphs which are bipartite or have exactly one multiple Laplacian eigenvalue. Other examples of interest are also presented.
We determine the spectrum of the McKay-Miller-ˇ Siráň graphs. It turns out these graphs have at most five distinct eigenvalues and sometimes are integral.
PURPOSE Retinal pigment epithelial (RPE) cells play key roles in the development of choroidal neovascularization and subsequent fibrosis. We investigated the impact of bevacizumab, antihuman vascular endothelial growth factor (VEGF) antibody, and anticonnective tissue growth factor (anti-CTGF) neutralizing antibody, individually or in combination, on… (More)
