Autoimmune Diseases

These types of diseases are caused when the body produces an immune response against substances which are present in the body naturally. These are mainly treated by immunosuppression due to which the immune response against that particular substance is reduced. Autoimmune diseases are among one of the most important which causes death of women in the age group of 65 years. 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.
