The examples in Figure 16 and Figure 17 demonstrate how system errors have a cascading effect, resulting in multiple errors being introduced into a single hypothesis string. The alignment examples shown are, by design, easy to understand and are easily derived. In practice, multiple errors frequently occur in a single hypothesis string resulting in many different possible alignments. The Scorin...

Synthesis of new 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone moiety containing 4-thiazolidinone moiety

A series of novel 1, 8-dioxo-octahydroxanthene derivatives containing 4-thiazolidinone framework (4a-f) were synthesized through a four-step reaction starting from the reduction of nitro derivatives of 1, 8-dioxo-octahydroxanthenes. The resulting aminoxanthenes converted to thiourea derivatives via their reaction with methyl isothiocyanate. The final products were synthesized through the re...

1 8 7 Lyme Borreliosis

Lyme borreliosis, or Lyme disease, is the most commonly reported arthropodborne illness in both the United States and Europe. 1 It was first recognized in the 1970s after epidemiologic investigations of a clustering of cases of oligoarthritis among children in eastern Connecticut established a probable microbial etiology for the disease. 2 In 1981, Burgdorfer isolated a new spirochetal bacteriu...
