The growth properties of a new panel of Bacillus subtilis tetL deletion strains and of a derivative set of strains in which tetL is restored to the chromosome support earlier indications that… Expand
Thrombocytopenia post liver transplantation. Correlations with pre-operative platelet count, blood transfusion requirements, allograft function and outcome.
This study reports that thrombocytopenia is a universal phenomenon post hepatic transplantation. In 53 consecutive adult patients undergoing liver transplantation the platelet count fell by a mean of… Expand
Challenges in the treatment of angiosarcoma: a single institution experience.
BACKGROUND Angiosarcomas are rare tumors that carry poor prognosis. Because of insidious growth rate, the diagnosis is often difficult and delayed. METHODS Between 1990 and 2011, 72 (41 female, 31… Expand

- 1 February 1997
Advanced‐stage lesions of the hypopharynx or tongue base often involve the larynx. The difficulty of reconstructing large partial laryngopharyngeal defects can result in total laryngectomy being… Expand
Clinical and manometric results of laparoscopic partial (Toupet) and complete (Rosetti-Nissen) fundoplication
AbstractIt is unclear whether a partial or complete gastric fundoplication done laparoscopically will offer the best control of reflux with the fewest side effects. Prospective evaluation of… Expand
An intergenic stem-loop mutation in the Bacillus subtilis ccpA-motPS operon increases motPS transcription and the MotPS contribution to motility.
