Weiss's lute music, the Moscow Manuscript is the next most important, in terms of the number of unique pieces. Tim Crawford's complete edition of the MS appeared recently, and an online version of the introductory matter, including incipits of the music, can be viewed here. Electronic Corpus of Lute Music A computer-assisted examination of the relationships between the lute music of Bach and Weiss, and of their predecessors and contemporaries, is among Tim Crawford's future plans. In order to achieve this, it will be necessary to build an electronic 'corpus' of lute music, and to devise ways of analysing the corpus using the latest techniques of information retrieval as they apply to music.
Performance and reported HCV protease resistance mutations. The majority of the participating laboratories detected most of the NS3 protease inhibitor resistance-associated substitutions. Twelve centers correctly identified all NS3 protease substitutions.
Four laboratories returned one incorrect result each, Qc4 transcription laboratories returned two incorrect results each, and 2 returned three erroneous results each. For 20 out of 23 laboratories, the nucleotide sequences of the neat and diluted samples containing the same RK mutant were strictly identical.
In one center, the difference was limited to the detection of a mixed population containing the expected substitution; in the two other laboratories, the error was related to contamination of the diluted sample in one case and sequencing troubleshooting in the other case Table 2.
Four centers obtained a wrong subtype result in one of the 12 samples of their panel. In all cases, this error resulted from contamination of the sample by another sample with a different subtype. Four panel samples were amplified, sequenced, and analyzed successfully by all of the laboratories: Overall, the sensitivity ranged from Incorrect results stemmed from a variety of causes.
For the false-positive results, in two centers, the source of the contamination was unknown. For the first one, a positive amplification signal was obtained, but the sequencing failed; for the second one, the contamination probably occurred with the AS mutant data not shown.
For the discrepant results, 4 centers returned an erroneous substitution in one sample of their panel. Qc4 transcription all cases, the nucleotide sequence was from another sample of the panel, suggesting cross-contamination. Nucleotide sequence alignment showed complete identity with another panel sample in 3 cases and a 3-nucleotide difference in one case data not shown.
Nucleotide and amino acid sequence alignments from the 23 participating centers showed a high sequence identity ratio for each of the six NS3 mutants and with the NS3 consensus sequence from the wild-type and resistant clinical strains included in the panel.
No differences in the ability to detect mutated codons were observed according to the type of substitution or between single and double mutants. The centers were also requested to report substitutions at NS3 residues Q41, F43, V, and D, known to be associated with decreased HCV susceptibility to protease inhibitors in vitro and in vivo 18 — One synthetic mutant carried a VM substitution, which was detected by all the centers.
Globally, when cross-contaminations and amplification issues were excluded, the amino acid sequences reported by the participating centers were identical to the expected ones. At the nucleotide level, mixed populations were reported for both natural strains and synthetic mutants.
When mutations other than those present in the samples of the panels distributed were reported, they never involved the protease resistance sites data not shown. This multicenter study demonstrates that laboratories with expertise in sequencing techniques are able to provide reliable HCV protease inhibitor resistance typing.
Only 20 incorrect results 0. NS3 resistance mutations have proven to be selected when interferon is not sufficiently active in the triple-therapy regimen and the virological response is impaired 5 Their detection before treatment or when virological breakthrough occurs could be important for patient follow-up and still needs to be explored, particularly with the recent wide use of protease inhibitors in clinical settings.
Collaborative multicenter studies are needed to evaluate the impact of these resistances and to determine whether this genotyping should be implemented for all patients in clinical practice, as it is for HIV Moreover, setting up a database of DAA resistance mutations will make it possible to compare data from clinical studies with data obtained in the field of clinical practice and will enrich our knowledge of viral resistance and its role in treatment failure in the era of DAA-based therapy.
The national quality control program we established with this goal obtained satisfactory adherence, with 23 complete responses out of 29 centers initially interested in participating.
The overall technical quality was good: Heterogeneity in the results was mainly related to the methodology used; 12 out of 19 centers using the AC33 protocol succeeded This could be explained by the fact that two samples in the panel could not be amplified when the primers used targeted a region outside of the nucleotide region between and according to HCV H77 1a coordinates.
Three out of 23 centers, which used exclusively the Mars F3 and Mars R2 primers that match between NS3 nucleotides andwere unable to generate results for these two samples. This risk of failure for certain primers was known before the panels were sent to the participating laboratories.Creating a documentary film is expensive and the filmmakers are doing a campaign to raise money to travel to complete the interviews, shooting, editing, transcription, graphics, music and post-production.
