The class of steroid hormones whose major function is influencing salt and water balances. These hormones were involved in retention of a mineral i.e., sodium, hence the name mineralocorticoids. The effect of mineralocorticoids is mediated by nuclear receptors as well as fast non-genomic mechanisms and signalling cascades. Aldosterone is the primary endogenous mineralocorticoids that are secreted by the adrenal glands. The other endogenous hormones with mineralocorticoid function are progesterone and deoxycorticosterone. Aldosterone increases the renal tubular reabsorption of sodium and secretion of potassium. The deficiency of mineralocorticoids causes severe renal sodium chloride wasting and hyperkalaemia. If total adrenocortical secretion is lost it leads to death in 2 days to 3 weeks. The individual can be saved if receives injections of mineralocorticoids or extensive salt therapy. Review articles are the summary of current state of understanding on a particular research topic. They analyse or discuss research previously published by scientist and academicians rather than reporting novel research results. Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
