Thyroid hormones production is controlled by the thyroid stimulating hormone. In children it is very important to regulate the control of thyroid hormone. The tissue which is present below the brain is the pituitary gland where it produces thyroid stimulating hormone. These thyroid stimulating hormone control and regulates the proper production of thyroid hormone. If these regulation does not occurs proper it leads to high or low level of thyroid hormone production and it leads to hypothyroidism and hyperthyroidism.
High-impact journals are those considered to be highly influential in their respective fields. 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.
