BACKGROUND Lymph node metastasis is believed to be a dependent negative prognostic factor of esophageal cancer. To explore detection methods with high sensitivity and accuracy for metastases to regional and distant lymph nodes in the clinic is of great significance. This study focused on clinical application of FDG PET/CT and contrast-enhanced(More)
During the period November 1972 through October 1974, 118 epidural blood patch procedures were performed for severe postlumbar-puncture cephalgia. Subsequently, in a period varying from 105 to 380 days, three patients, two of whom had twice undergone epidural blood patch, were readmitted for either surgical operation or delivery. Either epidural, caudal, or(More)

Since existing watermarking schemes usually have only a single function, a region-adaptive semi-fragile dual watermarking scheme is proposed, taking into account both watermark embedding capacity and security. The dual watermarks refer to the robust watermark and the fragile watermark. The original image is divided into three regions, i.e., a no watermark(More)
The Mast® D68C test is a phenotypical test that allows the detection of extended-spectrum β-lactamase (ESBL) production, even in AmpC-producing Enterobacteriaceae. We assessed its detection accuracy against a large collection of 106 Enterobacteriaceae isolates producing a wide diversity of well-characterized β-lactamases (53 ESBL producers, 25 Amp.(More)
Plasmid-mediated quinolone resistance mechanisms have become increasingly prevalent among Enterobacteriaceae strains since the 1990s. Among these mechanisms, AAC(6’)-Ib-cr is the most difficult to detect. Different detection methods have been developed, but they require expensive procedures such as Sanger sequencing, pyrosequencing, polymerase chain(More)
