Abstract: A genetic construct having a nucleotide sequence corresponding to a gene expression system or vector including the RNA or DNA polynucleotides hokD and ldrB isolated for use in medicine, particularly in gene therapy for cancer treatment. The invention also describes compositions comprising said polynucleotides or related gene constructs, and a method for treating proliferative disorders, preferably cancer.

Abstract: Embodiments of ignition systems, apparatus, and/or methods can provide exemplary voltage control or regulation for a voltage used for flame detection as well as for spark generation. In one embodiment, flame sensitivity and spark energy can have an increased resistance to component, temperature, and/or power supply variations.

Abstract: An ignition control and method are provided for overseeing an ignition process on a fuel-fired appliance having a fuel burner, a fuel flow control valve, an ignition source, and a flame detection device. A primary processor initiates the ignition process, monitors the flame status signal and terminates the ignition process in the presence of a flame status signal indicating no flame after a specified period of time following the initiation of the ignition process. A secondary processor monitors the flame status signal independently of the primary processor and terminates the ignition process in the event that the primary processor fails to terminate the ignition process in the presence of a flame status signal indicating no flame after a specified period of time following the initiation of the ignition process. The primary and secondary processors may each have the functional capability to monitor the operation of the other.
