Macrolide treatment failure in syphilis patients is associated with a single point mutation (either A2058G or A2059G) in both copies of the 23S rRNA gene in Treponema pallidum strains. The conventional method for the detection of both point mutations uses nested PCR combined with restriction enzyme digestions, which is laborious and time-consuming. We initially developed a TaqMan-based real-tim...

In a recent paper [Phys. Rev. E 69, 046121 (2004)]], we used the Suzuki-Trottere formalism to study a quasispecies biological evolution model in a parallel mutation-selection scheme with a single-peak fitness function and a point mutation. In the present paper, we extend such a study to evolution models with more general fitness functions or multiple mutations in the parallel mutation-selection...

In this paper, an adaptive neuro fuzzy sliding mode based genetic algorithm (ANFSGA) controlsystem is proposed for a pH neutralization system. In pH reactors, determination and control of pH isa common problem concerning chemical-based industrial processes due to the non-linearity observedin the titration curve. An ANFSGA control system is designed to overcome the complexity of precisecontrol o...

Abstract BACKGROUND: Mutations of NFkB1 are a known cause inborn errors immunity resulting in immunodeficiency due to the role as transcriptional regulator immunomodulating proteins. We present patient with diagnosis common variable (CVID), cytopenias massive splenomegaly, and nodular regenerative hyperplasia liver. Our proband, 22-year-old male, presents clinical picture immunodeficiency, has ...

A biological reporter gene assay was employed to determine the crucial parameters for maximizing selective targeting of a Ha-ras codon 12 point mutation (G----T) using phosphorothioate antisense oligonucleotides. We have tested a series of oligonucleotides ranging in length between 5 and 25 bases, each centered around the codon 12 point mutation. Our results indicate that selective targeting of...
