Lipid Fatty Acids from the Pericarp of Cydonia oblonga Mill. and Mespilus germanica L. are Involved in Plant Adaptation to Altitudinal Zonality.

The composition of fatty acids of total lipids of the outer and parenchymal parts of the pericarp in Cydonia oblonga Mill. and Mespilus germanica L. (Maloideae, Rosaceae), growing in the Northern Caucasian mountains at altitudes of 300, 500, 700, and 1200 m above sea level in various natural zones from experimental sites, was studied for the first time.

Tannosomes in the Pericarp Cells of Maloideae (Rosaceae).

Data on the presence of structural units termed tannosomes in the pericarp cells of Maloideae has been obtained for the first time. Tannosomes merge in the vacuoles to form "tannoglobules."

[Ecologic safety problems on industrial enterprises of Kolsky Transpolar area].

The authors presented results of ecologic and hygienic studies conducted in Kolsky nuclear power station area (Murmansk region). The studies found a trend to accumulation of summarized specific radioactivity and radionuclides of various origin in natural objects (woody plants, snow). Threshold concentrations of radionuclides in the studied objects appeared to be within the limits of normal radiation background.

Metalated diblock and triblock poly(ethylene oxide)-block-poly(4-vinylpyridine) copolymers: understanding of micelle and bulk structure.

The paper provides new insights into the structure of Pt-containing diblock and triblock copolymers based on poly(ethylene oxide) (PEO) and poly(4-vinylpyridine) (P4VP), using a combination of atomic force microscopy (AFM), X-ray diffraction (XRD), transmission electron microscopy (TEM), and anomalous small-angle X-ray scattering (ASAXS). Parallel studies using methods contributing supplemental structural information allowed us to comprehensively characterize sophisticated polymer systems during metalation and to exclude possible ambiguity of the data interpretation of each of the methods. AFM and TEM make available the determination of sizes of the micelles and of the Pt-containing micelle cores, respectively, while a combination of XRD, TEM, and ASAXS reveals Pt-nanoparticle size distributions and locations along with the structural information about the polymer matrix.
