Retrocaval ureter--a rare anomaly.
Retrocaval location of the ureter is a rare ontogenic vessel anomaly. In the present paper the authors report on four cases, discussing their diagnostic, clinical and therapeutic aspects.

Protein metabolism during germination of Bacillus megaterium spores. I. Protein synthesis and amino acid metabolism.
Protein synthesis during germination of Bacillus megayerium spores can be divided into two stages. During the first 75 min of germination (Stage I) endogenous nitrogen reserves are sufficient to support protein synthesis, and most amino acids are generated by proteolysis of dormant spore protein. The amino acids produced are excreted initially from the spore, but then reabsorbed and partially utilized for protein synthesis. Significant amino acid metabolism also occurs during Stage I, utilizing enzymes already present in the dormant spore. The biosynthesis of a number of amino acids is low or absent during Stage I due to the absence of biosynthetic enzymes. Subsequently, at defined times in Stage I, these missing enzymes are synthesized and amino acid biosynthesis is initiated. By the beginning of Stage II (from 75 min on) the developing spore has regained the capacity for synthesis of all amino acids and requires an exogenous nitrogen source for rapid protein synthesis.

Absence of 3'-terminal residues from transfer ribonucleic acid of dormant spores of Bacillus megaterium.
Essentially all (>97%) of the transfer ribonucleic acid (tRNA) in log-phase and sporulating cells of Bacillus megaterium contains a complete 3'-cytidyl-cytidyl-adenosine terminus. However, about one-third of the tRNA in the dormant spore lacks the 3'-terminal adenosine 5'-monophosphate (AMP) residue, and some of the adjacent cytosine monophosphate residues are also missing. Examination of specific tRNAs indicated that those specific for isoleucine, leucine, and methionine are missing 30 to 40% of their terminal residue, whereas tRNAs specific for tyrosine lack 88% of the 3'-terminal AMP. Defective spore tRNA is not degraded during germination, but the missing residues are added back in the first minutes of the process. The enzyme catalyzing the addition reaction, tRNA nucleotidyltransferase, is present in the dormant spore at a level similar to that found in the vegetative cell.
