Retrieval of DNA sequences present at an extremely low frequency.
We describe a method for retrieving sequences with one or two point mutations of a given target sequence, which are present in a DNA population at a frequency of 1 in 466 x 10(3) and 1 in 28 x 10(3) molecules, respectively. By stringent hybridization to a stable, chemically immobilized probe, a large excess of unrelated fragments is removed, and the bound sequences are dissociated and amplified...
متن کاملLizards respond to an extremely low-frequency electromagnetic field.
Animals from a wide range of taxa have been shown to possess magnetic sense and use magnetic compasses to orient; however, there is no information in the literature on whether lizards have either of these abilities. In this study, we investigated the behavioral responses of a diurnal agamid lizard (Pogona vitticeps) to a sinusoidal extremely low-frequency electromagnetic field (ELF-EMF; 6 and 8...
متن کاملInhibition of Salmonella typhi growth using extremely low frequency electromagnetic (ELF-EM) waves at resonance frequency.
AIMS Typhoid is a serious disease difficult to be treated with conventional drugs. The aim of this study was to demonstrate a new method for the control of Salmonella typhi growth, through the interference with the bioelectric signals generated from the microbe during cell division by extremely low frequency electromagnetic waves (ELF-EMW-ELF-EM) at resonance frequency. METHODS AND RESULTS Is...
متن کاملExtremely low frequency plasmons in metallic mesostructures.
The plasmon is a well established collective excitation of metals in the visible and near UV, but at much lower frequencies dissipation destroys all trace of the plasmon and typical Drude behavior sets in. We propose a mechanism for depression of the plasma frequency into the far infrared or even GHz band: Periodic structures built of very thin wires dilute the average concentration of electron...
متن کاملIntelligible encoding of ASL image sequences at extremely low information rates
American Sign Language (ASL) is a gestural language used by the hearing impaired. This paper describes experimental tests with deaf subjects that compared the most effective known methods of creating extremely compressed ASL images. The minimum requirements for intelligibility were determined for three basically different kinds of transformations: (1) gray-scale transformations that subsample t...
