Interindividual variability in drug metabolism and drug response is extensive. The causes for this are of genetic, physiological, pathophysiological, and environmental origin. Genetic variability is known for drug absorption, drug metabolism, and drug interactions with the receptors. Pharmacogenetics is defined as the genetics behind interindividual differences in drug response and includes studies of variants of genes encoding drug transporters, drug-metabolizing enzymes, and drug receptors. The aim is to understand the genetic factors of importance that explain no drug response in a large part of the population and the occurrence of adverse drug reactions. Today, we have most knowledge about the importance of the drug-metabolizing enzymes in this respect, whereas the research is progressing to yield a better understanding about to what extent genetic variability in drug transporters and drug receptors can explain adverse drug reactions and lack of drug response.

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.
