Methods for the preparation of stable 1,4,6,10-tetraazaadamantane quaternary derivatives were developed based on quaternization of a tertiary nitrogen atom in tris(β-oximinoalkyl)amines or isomeric 4,6,10-trihydroxy-1,4,6,10-tetraazaadamantanes. This process constitutes a convenient approach to the introduction of a hydrophilic 1,4,6,10-tetraazaadamantane moiety into lipophilic molecules in order...
Results from the 1993–2004 genetic monitoring of pink salmon populations reproducing in the rivers of Tauy Bay on the Sea of Okhotsk are analyzed. A statistically significant heterogeneity of samples as determined by gene frequencies is found only in the pink salmon generations of even years. The genetic differentiation of samples from even years (GST = 1.39 ± 0.41) is higher than that of odd years...
