Pharmacogenetics studies the inherited genetic differences in the metabolic pathways of drugs in terms of therapeutic actions. In simple, it is the study of how the actions of drugs in the human body vary with then patientsâ genes. It is based on the hypothesis that the differences in the drug actions from person to person is due to the presence or absence of special biomarkers which are single nucleotide polymorphs at the level of nuclear DNA, which code for the liver enzymes that are responsible for the pharmacokinetics of the drugs.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information.The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
