Hepatitis C 12/02009 By: Shuntrice Hannah Abstract Hepatitis C is an infection of the liver caused by the hepatitis C virus (HCV). It is difficult for the human immune system to eliminate the virus from the body‚ and infection with HCV usually becomes chronic. Over decades‚ chronic infection with HCV damages the liver and can cause liver failure in some people. The hepatitis C virus is transmitted mainly by contact with blood or blood products.

Enzyme Activity Lab Hypothesis: 1] Are enzymes reusable? Yes‚ enzymes are reusable. 2] Which of the following do you think contain catalase? [Manganese dioxide‚ chicken meat‚ apple‚ carrot‚ potato‚ or chicken liver] I think that the manganese dioxide‚ apple‚ and carrot contain the catalase. 3] Would grinding the materials affect enzyme activity? I think that grinding the materials will increase enzyme activity. 4] Would temperature affect enzyme activity? I think that

Hypothesis If liver is placed in different temperatures of 0˚C‚ 7˚C‚ 21˚C‚ 37˚C‚ and 90˚C and hydrogen peroxide is added to each piece of liver‚ then the liver placed in 37˚C will have the largest reaction height. The liver in 90˚C will have the smallest reaction height‚ followed by the liver in 0˚C‚ then 7˚C‚ and then 21˚C. Background Information Pearson Baccalaureate:

In the U.S. alone surgeons performed 5‚273 liver transplants in 2008‚ according to www.infopleas.com accessed on April 17‚2012. 2. Statement of Significance: Most people in the U.S. do not know if they are an organ donor or not. One way to find out is by looking at your driver’s license.

This hypothesis should have been proven true with the experiment‚ but due to some error the iced liver had the greatest rate of O2 production. Things that could have affected the rate of reaction could include: the iced liver being left in room temperature conditions too long before beginning the experiment‚ accidental added motion from moving the test tube during the reaction causing molecular collision to occur

Billy Graham‚ a professional WWWF wrestler is diagnosed with hepatitis‚ along with thousands of other people around the world. Due to the severity of Graham’s hepatitis‚ he had to undergo a liver transplant in 2002. Graham continues to have constant health problems today‚ most of which involve his liver.” (Superstar Billy Graham) “In 1965

esophageal varices is a disease process it is mainly caused by other conditions. Most notably are liver cirrhosis (caused by either alcohol abuse or hepatitis infection) and deep vein thrombosis of the mesenteric or portal veins. Because the only real symptom of esophageal varices is bleeding it is often only diagnosed after an episode of bleeding or as part of a work up for another condition such a liver cirrhosis. due to late diagnosis and the asymptomatic nature of this illness it can be fatal.

and‚ after biochemical alteration in the liver‚ becomes "conjugated" (or direct) bilirubin. Conjugated bilirubin is a major part of bile. Bile is a substance that breaks down fats‚ and is often yellow or brown in color. It is released into the small intestine by the gallbladder when it’s needed to break down fats that are being digested. When an abnormally high number of red blood cells are broken down‚ bilirubin can build up quickly in the body. Liver disease can also cause bilirubin levels to

He then showed signs of nausea‚ diarrhea‚ and confusion because his liver could no longer filter and remove waste from the blood. He died two days later from liver failure. 1.
