Metal oxides play a very important role in many areas of chemistry, physics, and materials
science. 1-5 The metal elements are able to form a large diversity of oxide compounds. 6�…

One of the principal functions of any epithelium in the embryonic or adult organism is to act
as a self-sealing barrier layer. From the earliest stages of development, embryonic epithelia�…

One of the first steps in segmentation of the Drosophila embryo seems to be not the
formation of segments, but instead the definition of 14 domains, each of which encroaches�…

The activation of MAPKs is controlled by the balance between MAPK kinase and MAPK
phosphatase activities. The latter is mediated by a subset of phosphatases with dual�…

The body plan of the mammalian embryo is shaped through the process of gastrulation, an
early developmental event that transforms an isotropic group of cells into an ensemble of�…

There is evidence that pluripotency of mouse embryonic stem (ES) cells is associated with
the activity of a network of transcription factors with Sox2, Oct4, and Nanog at the core. Using�…

New information about the active sites for the water gas shift (WGS) reaction over Cu− CeO2
systems was obtained using in-situ, time-resolved X-ray diffraction (TR-XRD), X-ray�…

Redox processes occurring during the CO–O2 reaction and catalytic properties for CO
oxidation have been examined for CuO/CeO2 and CuO/ZrCeO4 catalysts using catalytic�…

Mouse embryonic stem cells (mESCs) are clonal populations derived from preimplantation
mouse embryos that can be propagated in vitro and, when placed into blastocysts�…

Two series of nanostructured oxidized copper− cerium catalysts with varying copper
loadings, and prepared, respectively, by impregnation of ceria and by coprecipitation of the�…
