Opposite differential staining between sister chromatids was obtained by two silver-staining techniques on chromosomes replicated twice in medium containing 5-bromodeoxyuridine (BrdU) and pretreated with Hoechst plus black light. Both silver-nitrate and silver-carbonate staining were affected by chemical extraction and enzyme

Morphological features of the four morphotypes of the rumen ciliate, Eodinium posterovesiculatum, are described from pyridinated silver carbonate-impregnated specimens. Infraciliary bands are compared with those of Entodinium bursa and Diplodinium dentatum. In Entodinium bursa, the adoral polybrachykinety is "C" shaped

Decarboxylative Chan-Evans-Lam-type couplings are presented as a new strategy for the regiospecific construction of diaryl and alkyl aryl ethers starting from easily available aromatic carboxylic acids. They allow converting various aromatic carboxylate salts into the corresponding aryl ethers by reaction

Infraciliature and morphogenesis of six rumen ciliates, Ostracodinium mammosum, O. munham, O. dilobum, O. rugoloricatum, O. iwawoi, and O. tiete are described from pyridinated silver carbonate-impregnated specimens. These six Ostracodinium have a similar polybrachykinety arrangement, distinct from that of other
A simple, mild, and regioselective method has been developed for the selective benzylation and p-methoxybenzylation of carbohydrate derivatives in high yields using Ag(2)CO(3) as the promoter. Benzylation of base-labile substrates, for which other reported methods are of little use, has
