Hepatitis C virus (HCV) is a blood-borne disease that causes inflammation of the liver and to which there is currently no vaccine available. The World Health Organization (WHO) estimates that 3% of the world's population, approximately 170 million people, are infected with HCV and it is a leading cause of liver cirrhosis, end stage liver disease, hepatocellular carcinoma (HCC) and liver transplantation. http://www.physorg.com/news168179353.html Medicine & Health Thu, 30 Jul 2009 13:51:09 EST news168179353 Arctic springtails (Megaphorura arctica) survive freezing temperatures by dehydrating themselves before the coldest weather sets in.

Prior to 2000, African Americans were more likely to develop GIST and less likely to undergo surgical treatment for this type of cancer. http://www.physorg.com/news166792780.html Medicine & Health Tue, 14 Jul 2009 12:20:07 EST news166792780 A protein found in cells has been shown to play a pivotal role in determining whether a cell lives or dies. http://www.physorg.com/news166719345.html Biology Mon, 13 Jul 2009 15:56:09 EST news166719345 Coronary artery bypass surgery provides long-term benefits for children whose hearts and blood vessels are damaged by Kawasaki disease, Japanese researchers report in Circulation: Journal of the American Heart Association. http://www.physorg.com/news164907739.html Medicine & Health Mon, 22 Jun 2009 19:50:01 EST news164907739 An analysis of previous studies indicates that allogeneic stem cell transplantation (SCT) (stem cells from a compatible donor) is associated with significant overall and relapse-free survival benefit among adult patients with intermediate- and poor-risk but not good-risk acute myeloid leukemia in first complete remission, compared with nonallogeneic SCT therapies, according to an article in the June 10 issue of JAMA. http://www.physorg.com/news163822596.html Medicine & Health Wed, 10 Jun 2009 03:16:59 EST news163822596 Researchers have helped solve the mystery of why white men continue to earn 25 percent more than equally well-performing women and minorities.

The finding comes from a new analysis published in the May 15, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society. The study examined breast and prostate cancer survival rates at different geographic levels, and the results suggest that there are significant societal factors at the root of cancer-related racial disparities. http://www.physorg.com/news158835293.html Medicine & Health Mon, 13 Apr 2009 09:55:28 EST news158835293 Black patients suffering from lung cancer are less likely to receive recommended chemotherapy and surgery than white lung cancer patients, a disparity that shows no signs of lessening. That is the conclusion of a new study published in the May 15, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society. The study's findings indicate that efforts are needed to provide appropriate treatments for black patients and to educate them about the value of those treatments. http://www.physorg.com/news158835141.html Medicine & Health Mon, 13 Apr 2009 09:52:50 EST news158835141 A University of Minnesota cancer surgeon and researcher has found a dramatic increase in the number of women diagnosed with the earliest stage of breast cancer choosing to have both breasts surgically removed. http://www.physorg.com/news158493613.html Medicine & Health Thu, 09 Apr 2009 11:00:44 EST news158493613 Head and neck cancer patients who smoked, drank, didn't exercise or didn't eat enough fruit when they were diagnosed had worse survival outcomes than those with better health habits, according to a new study from the University of Michigan Comprehensive Cancer Center. http://www.physorg.com/news157809841.html Medicine & Health Wed, 01 Apr 2009 13:05:00 EST news157809841 (AP) -- A drug from Novartis has won U.S. approval as a treatment for patients with kidney cancer that has returned after treatment with older drugs. http://www.physorg.com/news157655661.html Medicine & Health Mon, 30 Mar 2009 18:14:46 EST news157655661 A new studying appearing in Congenital Heart Disease compares the careers and long-term occupational successes of men and women who underwent surgery for congenital heart disease to those of the general population.
