Adenocarcinoma of the cardia: does the extent of gastric resection and lymph node excision influence survival?
These results suggest that: a) palliative PSOG for AC can be performed with a low mortality; b) resection with extensive lymphadenectomy allows substantial survival regardless of the extent of gastrectomy.
The expression of the tyrS gene present in the TDC cluster of E. durans is transcriptionally regulated by tyrosine concentration and extracelular pH. The regulation is mediated by both an antitermination system and the promoter itself.
