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.
Histopathology can be defined as the microscopic examination of a biopsy or surgical specimen to study the manifestations of disease. In histopathology, the issue is taken off from the body by surgery, autopsy or biopsy then it is fixed over the glass slide as a method of stabilization and stained with dyes followed by examination under the microscope. The fixation is done to prevent tissue decay.
