Aldosterone is produced by the adrenal cortex. It helps in the regulation of blood pressure by acting on the distal tubules and collecting ducts of the nephrons which increases the re-absorption of ions and water in the kidneys. This leads to the secretion of potassium, conservation of sodium, increased blood pressure and retention of water. Aldosterone can be pathogenic if not regulated properly. It may also contribute to the development and progression of renal and cardiovascular diseases.
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.
