Cynops pyrrhogaster (the Japanese common newt) regenerates neural retina from retinal pigmented epithelium (RPE) cells. Otx2 is a transcription factor that is involved in RPE cell differentiation. To understand the role of Otx2 during transdifferentiation of RPE cells, we cloned a Cynops Otx2 cDNA, and explored its expression by RT-PCR, immunohistochemistry and in situ hybridization. The expres...

Muller context-free languages (MCFLs) are languages of countable words, that is, labeled countable linear orders, generated by Muller context-free grammars. Equivalently, they are the frontier languages of (nondeterministic Muller-)regular languages of infinite trees. In this article we survey the known results regarding MCFLs, and show that a language is an MCFL if and only if it can be genera...

This paper presents algorithm to find minimal Fixed Polarity Reed-Muller expressions, twolevel fixed polarity AND-EXOR canonical representations, for incompletely specified Boolean functions that based on information measures on decision trees. We study the Free Reed-Muller Tree as acceptable representation and manipulation structure to find minimal Fixed Polarity Reed-Muller expressions. In co...

Through two simple changes in the composition of the fixative for freeze-substitution of cryoimmobilized specimens, we are able to ameliorate the reproducible visibility of the plasma membrane in D. melanogaster embryos and larvae. The ultrastructural analysis of membrane-defective phenotypes of embryos fixed by our modified method should allow us a refined view on the plasma membrane and give ...
