and that it is betaine which serves as the immediate donor of methyl groups in transmethylation reactions. In view of an earlier finding that betaine was readily demethylated to glycine in the rat (4), it was considered of interest to compare injected isotopic choline and betaine as precursors of the glycine moiety of hippuric acid in the intact animal. The present finding that betaine and chol...

The present report summarizes a group of tracer experiments designed to test (1) whether desoxyribonucleic acid (DNA) and its associated histone are in a state of continuous nitrogen turnover in the avian red cell, (2) whether the rate of glycine incorporation into hemoglobin of the nucleated reticulocyte exceeds that observed in the mature erythrocyte, and (3) whether a difference in rate of s...

[1] Simultaneous all angle collocations (SAACs) of microwave humidity sounders (AMSU-B and MHS) on-board polar orbiting satellites are used to estimate scan-dependent biases. This method has distinct advantages over previous methods, such as that the estimated scan-dependent biases are not influenced by diurnal differences between the edges of the scan and the biases can be estimated for both s...

A myovirus-like temperate phage, PhiHAP-1, was induced with mitomycin C from a Halomonas aquamarina strain isolated from surface waters in the Gulf of Mexico. The induced cultures produced significantly more virus-like particles (VLPs) (3.73 x 10(10) VLP ml(-1)) than control cultures (3.83 x 10(7) VLP ml(-1)) when observed with epifluorescence microscopy. The induced phage was sequenced by usin...
