Over the last few decades, the amphibian Xenopus laevis1 has been used as a unique comparative model to study the developmental and immunological aspects of tissue transplantation as well as self tolerance (Du Pasquier, Schwager et al. 1989; Robert and Ohta 2009). The immune system of X. laevis, one of the best defined outside mammals and chickens, is fundamentally similar to that of mammals. N...

Oct-1 and a second, previously unidentified octamer-binding protein (Oct-R) have been identified in extracts of Xenopus laevis oocytes and embryos. Oct-1 does not bind to the octamer motif associated with certain Xenopus laevis histone H2B gene promoters, whereas Oct-R binds well to this motif, but only in the sequence context of the H2B gene promoter.

Common and dwarf bunt of wheat are recognized as being caused by three closely related species, Tilletia caries and T. laevis as common bunt, and T. controversa as dwarf bunt. The morphological characteristics of two species including T. controversa and T. caries were studied from wheat grown in two provinces of Iran, Lorestan and Chaharmahal–o-Bakhtiari duri...

Ehretia laevis Roxb. (Boraginaceae) has been extensively used as a traditional remedy for the treatment of diverse range ailments related to respiratory system, gastrointestinal tract, reproductive and against several infections. This review critically assesses documents, first time, fragmented information on E. laevis, including its botanical description, folklore uses, bioactive phyto metabol...

The aim of these experiments was to test whether the developmental potential of nuclei from intestinal epithelial cells of Xenopus laevis tadpoles declined during the life of the functional larval gut. The results of transplantation of nuclei from three different stages of development were compared: stages 46-48, when feeding begins and while yolk is still present but before the formation of th...
