A 19-year-old man was admitted to our hospital with anterior mediastinal cystic tumor. Subtotal thymectomy with the tumor was performed. The tumor was localized inside the thymus without outer infiltration. It weighed 145 g and measured 9 x 8 x 5 cm. The cut surface was cystic and spongy, partially with a solid focus. Pathological findings of the solid area was compatible with mucoepidermoid ca...

Rifaximin showed moderately high MICs (the MIC at which 90% of the isolates tested were inhibited = 50 microg/ml) for 145 bacterial enteropathogens from patients with traveler's diarrhea acquired in Mexico during the summers of 1997 and 1998. Rifaximin concentrations in stool the day after oral administration (800 mg daily for 3 days) were high (average, 7,961 microg/g), proving the value of th...

MicroRNAs (miRNAs) are small, non-coding RNAs that modulate gene expression by negatively regulating the stability or translational efficiency of their target mRNAs. The aim of this study was to investigate the expression of microRNA-145 (miR-145) in human papillary thyroid cancer and its potential function. Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was performed to...

MicroRNAs are important gene regulators that could play a profound role in tumorigenesis. Our previous studies indicate that miR-145 is a tumor suppressor capable of inhibiting tumor cell growth both in vitro and in vivo. In this study, we show that miR-145 exerts its function in a cell-specific manner. Although miR-145 inhibits cell growth in MCF-7 and HCT-116 cells, it has no significant effe...

The tumor suppressor p53 negatively regulates a number of genes, including the proto-oncogene c-Myc, in addition to activating many other genes. One mechanism of the p53-mediated c-Myc repression may involve transcriptional regulation. However, it is not clear whether microRNAs (miRNAs) play a role in the p53-mediated posttranscriptional regulation of c-Myc. In this study, we show that a putati...
