Adrenocorticotropic hormone (ACTH) is a polypeptide hormone produced by the anterior pituitary gland. It is an essential element of the hypothalamic-pituitary-adrenal axis. Biological stress is responsible to stimulate the release of ACTH from pituitary gland. It plays a key role in the production and release of corticosteroids from adrenal gland.The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number ofÂ citationsÂ to recent articles published inÂ science and social science journals in a particular year or period, and is frequently used as aÂ proxyÂ for the relative importance of a journal within its field. It is first devised byÂ Eugene Garfield, the founder of theÂ 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.
