<P>In this study, cryopreservation of Bratonia (Miltonia flavescens (Lindl.) Lindl. × Brassia longissima (Reichb.) Nash), a hybrid tropical orchid, was achieved using protocorm-like bodies (PLBs) multiplied in vitro. Cryopreservation was performed using a vitrification protocol including pretreatment of PLBs with a loading solution (LS, 2.0 M glycerol + 0.4 M sucrose) for 15 min followed by treatment with modified PVS2 vitrification solution (containing PEG instead of ethylene glycol) for 1 h. Increasing benzyladenine (BA) concentration in the recovery medium to 5.0 or 10.0 mg per liter during the initial 3 weeks after rewarming provided 20.4 percent post-cryopreservation regrowth. By contrast, preliminary culture of PLBs with abscisic acid (ABA) and high sucrose concentrations (up to 0.3 M) as well as addition of reduced glutathione during the preculture, loading and post-culture steps were not beneficial. Forty to 45 plants were regenerated from each PLB which withstood cryopreservation. No morphological differences were observed between plants regenerated from cryopreserved and untreated PLBs. Investigations into the functional activity of photosystems I and II in PLBs suggest that electron transport was retained in the reaction centers of both photosystems shortly after cryopreservation.</P>

Formation of Metastable Aluminides in Al–Sc–Ti (Zr, Hf) Cast Alloys

The effect of the ternary alloys composition and overheating of their melts (at 100–370 K above the liquidus temperature)on the morphology and composition of aluminides in the Al–Sc–Ti, Al–Sc–Zr, Al–Sc–Hf systems were investigated. It wasshown that during the crystallization of these melts under certain conditions, the primary precipitated phase are the complexaluminides Al3(ScxZr1−x), Al3(ScxTi1−x), Al3(ScxHf1−x) having a metastable cubic lattice with L12 structure, which matchesthe α-Al structural type. The variety of growth forms of aluminides is explained by a combination of a number of factors:the magnitude of overheating of the melt, the difference in the diffusion coefficients of transition metals, and the local concentrationof transition metals in the respective growth zones.

Background: The corneal and limbal morphology relevant to corneal epithelial maintenance in ten different species was examined using histological methods. Objectives: The presence of a Bowman’s layer, limbal epithelial cell, and superficial stromal morphology was examined in the following species to evaluate the differences in corneal thickness and epithelium: Java sparrows, frogs, macaws, spoonbills, red pandas, penguins, horses, Dobermans, orangutans, and humans. Methods: Corneal sections (4 μm) were obtained from ten ocular globes from three different animal classes: Aves, Amphibia, and Mammalia. All sections were stained with hematoxylin and eosin and periodic acid-Schiff reaction. After microscopy, all stained slides were photographed and analyzed. Results: Significant morphological differences in the corneal and limbal epithelia and their underlying stroma between species were observed. The number of corneal epithelial cell layers and the overall corneal epithelial thickness varied significantly among the species. The presence of a Bowman’s layer was only observed in primates (orangutans and humans). Presumed supranuclear melanin caps were noted in four species (orangutans, macaws, red pandas, and horses) in the limbal basal epithelial layer (putative site of corneal epithelial stem cells). The melanin granules covered the apex of the cell nucleus. Conclusions: Supranuclear melanin capping has been described as a process within the epidermis to reduce the concentration of ultraviolet-induced DNA photoproducts. Similarly, there may be a relationship between limbal stem cell melanin capping as a protective mechanism against ultra-violet radiation.
The Image of Japan in Tsarist Russia
Ariadna Popova 서울행정학회 2005 서울행정학회 학술대회 발표논문집 Vol.- No.-
In Tsarist Russia, the development of perceptions about Japan went alongside socio-cultural changes. The image of Japan developed as the image of "Other" within specific intercultural dialogue where the state had a leading role in accumulation of, and reflection on, the information about Japan in Russia. This paper examines the development of the image of Japan in social, political and cultural discourses of Tsarist Russia throughout the eighteenth, nineteenth and early twentieth centuries. In particular, the paper focuses on the reflection of representation of Japan in Russian foreign and domestic policy, in the intellectual life and in Art of Russian Modem.
