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.
Cell cycle or the division of cell leading to its duplication producing 2 daughter cells. During the development from stem cell to fully differentiated cells, cells in the body alternately divide (mitosis) and "appear" to be resting (interphase). This sequence of activities exhibited by cells is called the cell cycle. The regulation of cell cycle involves some processes crucial for the survival of the cell. These processes include the detection and repairing of the genetic damage as well as also to stop the uncontrolled cell division. The cell cycle events are highly ordered and cannot be reversed back. Cancer cells reproduce relatively quickly in culture. In the Cancer Cell CAM compare the length of time these cells spend in interphase to that for mitosis to occur.
