Background: This study was undertaken to establish the characterization of cultured oral mucosal epithelium and introducing them as an alternative source for reconstruction of ocular surface disease. Methods: Human oral epithelial cells were cultured on simple media (DMEM/HF12) as control and co-cultured on mitomycin C-treated 3T3 feeder layer, on the amniotic membrane (AM) without nitrocellulo...

  SUMMARY To study the effect of vero cells on preimplantation mouse embryos two groups of experiment were carried out. In experiment 1, pronuclear stage mouse embryos were co-cultured with Vero cells in RPMI medium and were examined under microscope for 4 days with 24h interval. The results showed co-cultured group developed better compared to control (87% to 80%, P<0.05) although, the rate ...

monogenetic termatodes are exoparasites of iranian freshwater fishes with high pervalency in both wild and cultured fishes which cause economoic loss each year. the aim of the present study was to detect parasites of gills in yellow- fin seabreams of persian gulf. this study was conducted for one year (between autumn 2007 to autumn 2008) on both wild and cultured yellow-fin seabreams of persian...

Efficient and selective electrical stimulation and recording of neural activity in peripheral, spinal, or central pathways requires multielectrode arrays at micrometer scale. At present, wire arrays in brain, flexible linear arrays in the cochlea and cuff arrays around nerve trunks are in experimental and/or clinical use. Twoand three-dimensional brush-like arrays and sieve arrays, with around ...

Sixty years ago, the notion that animals could have culture was unthinkable to most behavioral scientists. Today, evidence for innovation, transmission, acquisition, long-term maintenance, and intergroup variation of behavior exists throughout the animal kingdom. What can the longitudinal and comparative study of monkeys handling stones tell us about how culture evolved in humans? Now in its 30...
