We evaluated the ability of 60 Italian clinical microbiology laboratories in detecting and reporting beta-lactam resistance phenotypes in Enterobacteriaceae. Laboratories received 5 well-characterized isolates producing extended-spectrum beta-lactamases (ESBLs), 2 hyperproducers of chromosomal enzymes, and 3 quality control strains. The performances in(More)
BACKGROUND The expression of CD70 on T cells is greatly enhanced by antigen-presenting cell (APC)-associated signals, such as tumour necrosis factor(TNF)-α, which is constitutionally high in patients with inflammatory bowel disease (IBD). Experimentally, the chronic activation of CD27 as a result of the constitutive expression of CD70 leads to the demise of(More)
The lung carcinoma cell line Calu3, which overexpresses the c-erbB-2 oncogene, was stably transfected with antisense (AS) cDNA constructs encompassing different regions of the c-erbB-2 gene. Transfected cells were analyzed for their tumorigenic properties in vitro and in nude mice. Two independent clones, AS F1 (low erbB-2 expressor) and AS B12 (high erbB-2(More)
