The aim of the study described here was to clarify diagnostic value fluttering sign, a new sign that characterizes hepatic hemangiomas in gray-scale ultrasonography (US). It refers phenomenon which speckled echogenicity inside hemangioma changes continuously and seems be moving. A total 172 diagnosed with contrast-enhanced US were evaluated. found 123 (71.5%). Its prevalence significantly highe...

In yeast cells, mutations in the TATA-binding protein (TBP) that disrupt the interaction with the TATA element or with TFIIA can selectively impair the response to acidic activator proteins. We analyzed the transcriptional properties of TBP derivatives in which residues that directly interact with TFIIB were replaced by alanines. Surprisingly, a derivative with a 50-fold defect in TBP-TFIIB-TAT...

genic medicine, and it has been used as a crude drug to treat stress-induced physiological changes, various allergic conditions, inflammation and cancer. An aqueous extract of the stem bark of A. senticosus HARMS (ASH) from Japan and its components, chlorogenic acid (CHA) and syringaresinol di-o-b-D-glucoside (SYG), markedly prevent the ulcerogenesis in rats subjected to restraint stress in wat...

The cystic fibrosis (CF) transmembrane conductance regulator (CFTR) plays a crucial role in mediating duodenal bicarbonate (HCO(3)(-)) secretion (DBS). Although impaired DBS is observed in CF mutant mice and in CF patients, which would predict increased ulcer susceptibility, duodenal injury is rarely observed in CF patients and is reduced in CF mutant mice. To explain this apparent paradox, we ...
