Abstract: Tissue ligation systems and methods are provides to mechanically strangulate abnormal or undesirable tissue. Tissue ligation systems include a multi-lumen catheter having an outer diameter smaller than the inner diameter of a standard endoscope channel such that the catheter can be inserted into the endoscope. Tissue ligation systems also include a ligation apparatus with an expandable hood disposed at the distal end of the catheter. A suture extends through a lumen of the catheter and has a distal loop portion that can strangulate tissue.

Abstract: Various methods for determining whether a subject has alcoholic hepatitis are described. In one aspect, a method for determining whether a subject has alcoholic hepatitis is described. The method includes determining the levels of a trimethylamine in a biological sample obtained from the subject. The level of trimethylamine in the biological sample is compared to the control value, and the subject whose level of trimethylamine exceeds the control value is diagnosed as having alcoholic hepatitis. In another aspect of the present invention a method for assessing a subject as having alcoholic hepatitis (AH) includes determining the level of trimethylamine and the level of pentane in a biological sample obtained from the subject. A TAP score is determined based on the concentration of trimethylamine and the concentration of pentane. The subject is diagnosed as having alcoholic hepatitis if the TAP score exceeds a control value.

Abstract: A method of detecting liver damage in a subject comprises measuring the level of caspase-3 generated cytokeratin-18 fragments in the bodily sample. The level of measuring the level of caspase-3 generated cytokeratin-18 fragments is then correlated with liver disease progression.
