By Winter of 2004 at least three handheld nucleic acid analyzers—the Smiths Detection BioSeeq, the Idaho Technology, Inc. Razor, and the Nanosphere Verigene— 7. will be available for use. The first two instruments will rely on PCR-mediated amplification of the DNA or RNA template, whereas the Verigene relies on its proprietary nanoparticle-mediated hybridization format to detect 8 target nucleic acids. Other devices that promise the same degree of portability may become available in 2004 and offer the end-user the ability to extract DNA or RNA from a variety of sample matrices and volumes. With continuous advances in highly active fields of research such as microfluidic systems, micro-total analysis systems (mTAS), nanotechnology-based ''lab on a chip'' devices, 9. and microelectromechanical systems (MEMS), the future looks very exciting for the advent of novel handheld molecular biology-based devices suitable for use in the field and at the point of care.

Getting Started With Dumbbells

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
