Small noncoding RNAs (sRNAs) are a group of regulatory RNA molecules normally without a protein-coding function. In recent years, the importance of sRNAs as mediators of gene expression in bacteria has begun to be recognized. More than 70 sRNAs have been known in Escherichia coli. However, little is known about sRNAs in Helicobacter pylori, a human pathogen(More)

The point mutation in the precore region of hepatitis B viral genome (nt83) was tested with the method of mispairing PCR-RFLP in 54 chronic hepatitis B patients all confirmed by liver biopsy. The over all detection rate of pre-C mutation was 66.7% and the detection rate of pre-C mutation in chronic active hepatitis patients was as high as 80.0%, being(More)
