Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

An antisense oligonucleotide and the use thereof. A series of ASOs are designed on the basis of the genome sequence of a hepatitis B virus (HBV), and are modified by means of using a specific modification mode. Cell and animal experiment results show that some modified ASOs obtained by means of using the specific modification mode can significantly reduce the expression of one or more HBV genes and block the life cycle of viruses, and therefore can be used to develop drugs for treating HBV infection-related diseases.
