To clarify the phylogenetic relationships and species status of Pneumocystis, the 5.8S rRNA gene and the internal transcribed spacers (ITS, 1 and 2) of Pneumocystis rRNA derived from rat, gerbil and human were amplified, cloned and sequenced. The genetic distance matrix of six Pneumocystis species compared with other fungi like Taphrina and Saccharomyces indicated that the Pneumocystis genus contained multiple species including Pneumocystis from gerbil. The phylogenetic tree also showed that Pneumocystis from human and monkey formed one group and four rodent Pneumocystis formed another group. Among the four members, Pneumocystis wakefieldiae was most closely related to Pneumocystis murina and Pneumocystis carinii, and was least related to gerbil Pneumocystis.
We formulate the general problem of evaluating the
Molecular equilibrium structures, the harmonic frequencies and the anharmonic
Coefficients of an error affected potential energy surface. The proposed
Approach, based on a multidimensional fitting procedure, is illustrated
Together with a critical e...
An algorithm for SIMD parallelization based on grouping a fixed number of
Particles, e.g. 2, 4, or 8, into spatial clusters. Calculating all interactions
Between particles in a pair of such clusters improves data reuse compared to
The traditional scheme and results in a more efficient SIM...
Develop a novel phyloclassification method based on signatures derived from
Bioinformatically defined tRNA Class-Informative Features (CIFs). tRNA CIFs are
Enriched for features that underlie tRNA-protein interactions. Using a simple
TRNA-CIF-based phyloclassifier, we obtained results consistent...
