The aim of this trial was to compare the results obtained using laser ablation (LA) and radiofrequency ablation (RFA) to treat small hepatocellular carcinomas (HCC). From 2003 to 2005, a total of 81 cirrhotic patients (59 Child-Pugh A, 22 Child-Pugh B) presenting a total of 95 HCC nodules (mean diameter 27.9 mm) were treated with LA (41) and RFA (40).(More)
Receptors for the major excitatory neurotransmitter glutamate include metabotropic (G protein-coupled) and ionotropic (glutamate-gated ion channel) types. These receptors have large, presumably extracellular, amino-terminal domains. Sensitive sequence analysis techniques indicate that the metabotropic receptor extracellular domain is similar to bacterial(More)
BACKGROUND Few studies have evaluated the impact of the upright position on the success of oral-tracheal intubation. Yet, for patients with airway difficulties (i.e, active intraoral bleeding or morbidly obese), the upright position may both benefit the patient and facilitate intubation. OBJECTIVES We compared the success rates of subjects performing(More)
This study evaluated the feasibility of magnetic resonance (MR) volumetry using a diffusion-weighted data set (VDWI) and compared it with conventional T2-weighted volumetry (VC) in patients affected by rectal cancer treated with chemoradiation therapy (CHRT). Fourteen patients with a biopsy diagnosis of rectal cancer underwent MR examination before and(More)
Most current implementations of motif matching in biological sequences have sacrificed the generality of weight matrix scoring for shorter runtimes. The program MOTIF incorporates a weight matrix and a rapid, backtracking tree-search algorithm to score motif compliance with greatly enhanced performance while placing no constraints on the motif. In addition,(More)
