DoubleTwist used powerful supercomputers provided by Sun Microsystems to search the raw genome sequence looking for telltale patterns representing the genes and comparing unknown sequences with those of known genes.
The analyte identification was performed based on the retention time of analytes and their fragmentation pattern comparing unknown and standard samples.
The CBS-KNAW Fungal Biodiversity Centre, MycoBank and the recently launched BOLD mirror, EUBOLD, are also proposing online identification tools that can compare unknown sequences simultaneously against several reference databases.
Identifications are usually made by comparing unknown sequences against known species DNA barcodes via distance-based tree construction [ 7, 10, 11], alignment searching (e.g., BLAST; [ 12, 13]), or methods recently proposed such as the characteristic attribute organization system (CAOS) [ 14], decision theory [ 15], and the back-propagation neural network (BP-based species identification) [ 16].
We observed a 9% reduction in unknown grade disease in 2003 2007 compared with unknown grade disease in 1997 2002.
This is one of the rare cases in which the authors detailed the actual values of patients improved without suffering ADR; the authors compared an unknown test drug with a standard one jointly with hydrochlorothiazide to control blood pressure.
Furthermore, THR patients using NOACs or LMWHs had a higher BMI as compared to unknown users.
Compared to unknown users, all other groups showed a different distribution across the four major regions.
Aspirin users, however, were different as compared to unknown users particularly with regard to a history of ischaemic heart disease.
As expected, aspirin users were very different compared to unknown users with regard to comorbidities and drug use (table 3).
