Open access to the scientific literature means the removal of barriers (including price barriers) from accessing scholarly work. There are two parallel âroadsâ towards open access: Open Access articles and self-archiving. Open Access articles are immediately, freely available on their Web site, a model mostly funded by charges paid by the author (usually through a research grant). The alternative for a researcher is self-archivin (i.e., to publish in a traditional journal, where only subscribers have immediate access, but to make the article available on their personal and/or institutional Web sites (including so-called repositories or archives)), which is a practice allowed by many scholarly journals.
Open Access raises practical and policy questions for scholars, publishers, funders, and policymakers alike, including what the return on investment is when paying an article processing fee to publish in an Open Access articles, or whether investments into institutional repositories should be made and whether self-archiving should be made mandatory, as contemplated by some funders.
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.
