Although the Korean isolate KI-1 of Toxoplasma gondii has been considered to be a virulent type I lineage because of its virulent clinical manifestations, its genotype is unclear. In the present study, genotyping of the KI-1 was performed by multilocus PCR-RFLP and microsatellite sequencing. For 9 genetic markers (c22-8, c29-2, L358, PK1, SAG2, SAG3, GRA6, BTUB, and Apico), the KI-1 and RH stra...

Histocompatibility antigens were determined in 60 patients with psoriatic arthritis. The patients were divided into clinical subgroups according to axial or peripheral joint involvement, disease severity based on number of peripheral joints involved, and the presence or absence of bone erosions. The total group showed a significant increase in frequency of HLA-A1, B17, B27, and DR7 when compare...

Major histocompatibility (B) complex haplotypes BQ and B17 were examined for their effect on Rous sarcoma outcome. Pedigree matings of BQB17 chickens from the second backcross generation (BC2) of Line UCD 001 (BQBQ) mated to Line UCD 003 (B17B17) produced progeny with genotypes BQBQ, BQB17, and B17B17. Sixweek-old chickens were injected with subgroup A Rous sarcoma virus (RSV). The tumors were ...

BACKGROUND The Escherichia coli peptide antibiotic microcin B17 (MccB17) contains thiazole and oxazole heterocycles derived from a distributive yet directional cyclization of cysteines and serines in the McbA precursor catalyzed by MccB17 synthetase. Whether the formation of upstream rings potentiates downstream heterocyclization has not been previously determined. RESULTS McbA fragments (46-...

Abstract DNA gyrase, a type II topoisomerase found predominantly in bacteria, is the target for variety of ‘poisons’, namely natural product toxins (e.g. albicidin, microcin B17) and clinically important synthetic molecules fluoroquinolones). Resistance to both groups can be mediated by pentapeptide repeat proteins (PRPs). Despite long-term studies, mechanism action these protective PRPs not kn...

Abstract. Traffic congestion is a dynamic spatial and temporal process as such might not be possible to model with linear functions of various dependent variables. That leaves lot space for non-linear approximates, neutral networks fuzzy logic. In this paper, the focus on logic approach dealing problems measuring traffic congestion. We investigate application framework selected case study, use ...
