The thyrotrope cells in the anterior pituitary gland secrete thyroid-stimulating hormone (TSH) in response to thyrotropine releasing hormone. TSH stimulates the thyroid gland to produce thyroxine (T4) and triiodothyronine (T3) which are necessary to regulate body mechanism. T4 and T3 are very much essential to promote growth during childhood.The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number ofàcitationsàto recent articles published in science and social science journals in a particular year or period, and is frequently used as aàproxyàfor the relative importance of a journal within its field. It is first devised byàEugene Garfield, the founder of theàInstitute 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.
