OBJECTIVES Infants with slight/mild or late-onset hearing impairment might be missed in universal newborn hearing screening (UNHS). We identified the mutation hot spot of common deaf gene in the newborns in Jinan area population by screening the mutation spot with neonate cord blood, in order to make clear whether the neonate cord blood for screening is feasible. METHODS Six hundred and forty...
A premature female Dirofilaria species, subsequently identified as Dirofilaria repens by its morphological features and mitochondrial 12S ribosomal RNA (12S rRNA) gene sequence, was removed from a subcutaneous nodule of the right temporal region of the head in a Japanese woman 2 years after she noticed swelling of her left calf following an insect sting during a tour to Europe; headache symptom...
In a recent report published in this journal, Y. Qian and M.-X. Guan reported on their studies on interaction of aminoglycosides with human mitochondrial 12S rRNA carrying the A1555G deafness-associated mutation (15). Using RNA oligonucleotides representing the small subunit’s rRNA decoding A site (i.e., the drug binding pocket) and carrying the A1555G mutation, the authors used chemical footpr...

Mechanisms of ITS2 excision from pre-rRNA remain largely elusive. In mammals, at least two endonucleolytic cleavages are involved, which result in the transient accumulation of precursors to 5.8S rRNA termed 8S and 12S RNAs. We have sequenced ITS2 in four new species of the Mus genus and investigated its secondary structure using thermodynamic prediction and comparative approach. Phylogenetic e...
Analyses of the Trypanosoma equiperdum (ATCC 30019) maxicircle reveals deletions, duplications and rearrangement compared to T. brucei. The genes for 9S rRNA and 12 proteins are absent. The 12S rRNA and cytochrome oxidase subunit I (COI) genes lack their 3' ends and are adjacent indicating deletion of intervening genes. The remaining two NADH dehydrogenase subunit genes (ND4 and ND5), the ribos...
A species complex hypothesis involving Astyanax fasciatus from southern Brazil was tested using 12S mtDNA sequences. Phylogenetic inferences were performed with maximum likelihood, maximum parsimony and Bayesian as phylogenetic methods and Hemigrammus bleheri as the outgroup. Besides 11 sequences from A. fasciatus, the data set was comprised of other partial 12S sequences including material fro...
A duplex real-time polymerase chain reaction (PCR) based assay for the detection of porcine and horse meat in sausages was designed by using EvaGreen fluorescent dye. Primers were selected from mitochondrial 12S rRNA and 16S rRNA genes which are powerful regions for identification of horse and porcine meat. DNA from reference samples and industrial products was successfully extracted using the ...
