Apoptosis causing organisms are well adapted to the hostile environment of phagocytic cells and use several survival strategies not seen in other bacteria. The role of apoptosis in modulating the pathogenesis of the disease is probably similar in some aspects. Clinical apoptosis articles are accessible to all the readers that are published online. 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.
