Histopathology is the microscopical examination of various forms of biological tissues to detect the appearance of diseased cells and tissues in very fine detail. The word "histopathology" is coined from a combination of three Greek words: histos meaning tissue, pathos meaning disease or suffering, and logos meaning study.A tissue diagnosis can be made on the basis of biopsy material taken from the patient on the ward or in the operating theatre, or from autopsy material.
Histopathology is the study of microscopic changes or abnormalities in tissues that are resultant of diseases. The main use of histopathology in clinical medicine is examination of a biopsy or surgical specimen by a pathologist, after the specimen has been processed and histological sections have been placed onto glass slides.
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.
