| characterization and mapping of the agrocinopine-agrocin 84 locus on the nopaline ti plasmid ptic58. | overlapping segments of ptic58 inserted into cosmid vectors were used to characterize the agrocinopine-agrocin 84 locus from the nopaline/agrocinopine a and b agrobacterium tumefaciens strain c58. all of the clones conferring agrocin 84 sensitivity on agrobacteria also conferred uptake of agrocin 84 and agrocinopines a and b. transposon tn3-hoho1 insertion mutations of one such clone were generated that simultaneously abolished agrocin 84 sensitivity and transport of agrocinopines a and b and ag ... | 1988 | 2832379 |
| primary signet-ring cell carcinoma of urinary bladder. | a case of primary signet-ring cell carcinoma of the urinary bladder is described clinically and pathologically. in this rare neoplasm the characteristic cells contain large amounts of cytoplasmic mucin which compresses the nucleus to one side. this tumor demonstrates nicely the ability of bladder epithelium to undergo metaplasia. most previously described cases have pursued a relentlessly progressive and fatal course despite varied forms of therapy. | 2010 | 2834858 |
| properties of the membrane-bound 5'-nucleotidase and utilization of extracellular atp in vibrio parahaemolyticus. | vibrio parahaemolyticus utilized atp, adp or amp as the sole source of carbon. about three times higher activity of membrane-bound 5'-nucleotidase was observed in cells grown in the presence of these nucleotides than in their absence: and therefore the enzyme seems to be inducible. since the 5'-nucleotidase activity could be measured with whole cells, the active site of this enzyme appears to be outwardly oriented. both mg2+ and cl- were required for activity. among the divalent cations tested, ... | 1987 | 2835422 |
