Much of the individual variation in drug response is due to genetic polymorphisms of drug-metabolizing enzymes, and genomic testing for drug-metabolizing enzymes has significant potential for improving the efficiency of drug treatment and reducing adverse drug reactions and thus promises to improve future health care in a number of ways. It is very likely that these tests will make up a significant proportion of total nucleic acid-based testing in the coming years. Currently, however, only a few pharmacogenetic tests and associated products are commercially available, and most are for research use only. Pharmacogenetic tests pose fewer risks for the patient than genetic tests for disease mutations; however, these tests still raise several ethical, economical, and regulatory issues that need to be addressed before they can be integrated into medicine in a large scale.
Nucleic acid-based technology is considered to be of critical importance to public health worldwide and is transforming clinical microbiology, pathology, genetics, pharmacogenetics, prenatal, and preimplantation medi-cine. Nucleic acid-based technology will also have a significant impact on forensic diagnostics, veterinary medicine, food hygiene and technology, and monitoring of genetically modified agricultural products.

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.
