The question of Shem the Penman that opens chapter seven of Finnegans Wake—When is a man not a man—and the range of answers that it elicits, represents just one of many instances in which phenomenological pursuits and the concomitant inadequacy of terms come to the foreground of Joyce's work. No matter whom one reads, however, in any given situation labels / signifiers / designations more often...

Photosystem I of higher plants is characterized by red-shifted spectral forms deriving from chlorophyll chromophores. Each of the four Lhca1 to -4 subunits exhibits a specific fluorescence emission spectrum, peaking at 688, 701, 725, and 733 nm, respectively. Recent analysis revealed the role of chlorophyll-chlorophyll interactions of the red forms in Lhca3 and Lhca4, whereas the basis for the ...

PURPOSE To determine the effect of amniotic membrane-conditioned medium (AMCM), via insulin-like growth factor (IGF)-1 induction, on human corneal epithelial cell (HCEC) proliferation. METHODS HCECs were cultured from corneal limbal tissue with supplemented hormonal epithelial medium (SHEM). After administration of AMCM, cell proliferation was evaluated with an MTT assay and DNA synthesis wit...

PURPOSE To determine the growth potential of p63-positive cell clusters maintained in human limbal epithelial sheets. METHODS Intact human limbal epithelial sheets were isolated from corneoscleral rims and cultured with or without being rendered into single cells by trypsinization on either plastic or 3T3 fibroblast feeder layers. Clonal growth on 3T3 fibroblast feeder layers was compared bet...

Lhc proteins constitute a family of transmembrane proteins which share homology in sequence and similarity in the general organisation although members can be strongly differentiated such as in the case of PsbS and ELIPs. In this work, we report on the structure of Lhca3, a pigment-protein subunit component of the antenna system of higher plants Photosystem I, through the effect of point mutati...

Past attempts to grow human corneal epithelium in culture had limited success, with confluence rarely attained. This work is to determine whether different areas of human corneal epithelium grow better in tissue culture. We compared the extent, the mitotic rates, and morphology of outgrowths and histology of explants from central and peripheral human corneas in culture. Explants, 2 mm in diamet...

This research focuses on the comparative analysis of PWR fuel assembly based VERA depletion benchmark problems using community-developed open source Monte Carlo code OpenMC, python burnup system ONIX (a coupling interface for OpenMC), and deterministic DRAGON code. The was performed OpenMC with ENDF/B-VII.1 nuclear data library, SHEM-361 DRAGLIB format library (ENDF/B-VII.1). code-to-code evolu...
