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.
Hepatic Steatosis is referred to fatty liver which is caused due to the excessive amount accumulation of triglycerides and other types of fats. The major cause of the hepatic steatosis is consumption of alcohol in high amount which directly affects liver cells. Other risk factors for the development of fatty liver are type 2 diabetes, insulin resistance and high cholesterol. Steatosis is more common in women, and may also appear in thin people with low alcohol intake in smaller proportions. Both hepatic steatosis and steatohepatitis and cause no symptoms (they are asymptomatic) in early stages and are usually discovered incidentally in ultrasound or CT scans. The condition is generally not painful and may go unnoticed for a long period of time. In severe cases, the liver can increase to over three times its normal size and may be painful and tender.
