Recent laws passed to protect music and extend copyright for certain works have made it so that the latest copyright date for a piece of music to be considered public domain is 1923. Anyone can create a version or arrangement of a public domain song, and then copyright that version under his/her name. This makes this particular arrangement of the song untouchable by anyone except the arranger, even though the original song from whence it came is still part of the public domain.
Aminoglycosides can cause eighth cranial nerve damage, resulting in vestibular and/or auditory toxicities. Symptoms include dizziness, nystagmus, vertigo, ataxia, tinnitus, and varying degrees of hearing impairment.
Mechanism of action. Aminoglycosides like neomycin irreversibly bind to specific 30S-subunit proteins and 16S rRNA. Specifically neomycin binds to four nucleotides of 16S rRNA and a single amino acid of protein S12. This interferes with decoding site in the vicinity of nucleotide 1400 in 16S rRNA of 30S subunit.This region interacts with the wobble base in the anticodon of tRNA.pecifically neomycin binds to four nucleotides of 16S rRNA and a single amino acid of protein S12.
