Nanocrystals of oxides containing europium as the main constituent or as a doping element in RE2O3 ( RE=Y, Gd) have been prepared by direct oxide precipitation in high-boiling polyalcohol solutions and characterized by high-resolution TEM, absorption spectroscopy, and luminescence spectroscopy. The samples obtained consisted of concentrated and colloidally(More)
The function of transforming growth factor-beta (TGF-beta) in vivo remains unknown despite the fact that it has been identified in numerous biologic processes involving the regulation of cell growth including tissue repair. Doxorubicin is a potent antitumor drug that has been shown to have detrimental effects on wound healing. With specific complementary(More)
Size effects, such as structure transition, have been reported in small clusters of alkali halide compounds. We extend the study to rare earth sesquioxide (Gd(2)O(3)) clusters which are as ionic as the alkali halide compounds, but have a more complicated structure. In a clean and controlled environment (ultra high vacuum), such particles are well(More)
Knowledge of normal differentiations is indispensable for interpreting developmental disturbances in animal experiments. Accordingly, the investigations described in the present paper were aimed at explaining the process of myelinization of the optic nerve in the domestic mouse breed Agnes Bluhm Jena-Halle. First signs of myelin sheath formation can be seen(More)
Organ toxicity is the major limiting factor associated with chemotherapeutic treatment of malignancy. By raising the toxicity threshold of the organ to the detrimental effects of chemotherapeutic agents, larger and possibly curative doses may be administered without unacceptable side effects. Glutathione (GSH), a major nonprotein cellular thiol,(More)
