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.
Liver biopsy is a type of surgical procedure which is done for the diagnosis of any kind of disease related to the liver such as liver cirrhosis, jaundice, Hemochromatosis etc. There are three types of liver biopsy- Percutaneous biopsy, Transvenous biopsy, Laparoscopic biopsy.
Liver biopsy is often used to diagnose the cause of chronic liver disease that results in elevated liver tests or an enlarged liver. If the diagnosis is known, such as hepatitis C, then the main reason for a liver biopsy is to determine whether the patient has a progressive disease. Mainly liver biopsy is very rarely used to treat any other disease than liver cancer. Patients who have undergone liver transplantation often require numerous liver biopsies in the early weeks to months following the surgery to allow accurate diagnosis of whether the new liver is being rejected or whether other problems have developed. However it is a potential method know n for such situation but it is associated with few complications as well.
