Do You Read All Of Our Cancer Blogs?
Do you read all of the blogs published by medicineworld.org? Many of our bloggers are busy keeping you updated on the various health related topics. We publish the following blogs at this time.
I manage the cancer blog with lots of help and support form other bloggers. Through this cancer blog my friends and I try to bring stories of hope for patients with cancer. The cancer blog often republishes important blog posts from other cancer related blogs at Medicineworld.org. If you are searching for a blog that covers wide variety of cancer topics, this may be the one for you.
Breast cancer blog:
Breast cancer blog is run by Emily and other bloggers and they bring you the latest stories, news and events that are related to breast cancer. Increasing awareness about breast cancer among women and in the general population is the main goal of this breast cancer blog.
Lung cancer blog:
Lung cancer blog is managed by Scott with the help of other bloggers. Through this blog Scott and his friends constantly remind the readers about the dangers of smoking. It's a never-ending struggle against this miserable disease with which a social stigma of smoking is associated.
Colon cancer blog:
Colon cancer blog is run by Sue and other bloggers. Sue brings a personal touch to the colon cancer blog since her mother died of colon cancer few years ago. She writes about stories, research news and advances in treatment related to colon cancer.
Prostate cancer blog:
Prostate cancer is the most common cancer among American men. American Cancer Society estimates that over 230,000 new cases of prostate cancer occur in the United state every year. This important blog about prostate cancer is run by Mark and other bloggers. This blog brings news, stories, and other personal observations related to prostate cancer.
Medicineworld.org publishes a diabetes watch blog
and this blog is run by JoAnn other bloggers. This diabetes watch blog brings you the latest in the field of diabetes. This includes personal stories, advances in diagnosis and treatment, and other observations about diabetes. Improving awareness about diabetes is an important mission of this group.
Molecular Imaging For Plaques
Diagnostic strategies at the molecular level are being developed that "should be able to detect atherosclerotic plaques likely to rupture in the arteries that supply blood to the heart and brain," as per a studyin the recent issue of the Journal of Nuclear Medicine.
This is important news for about 14 million people in the United States who suffer from coronary artery disease and the 1.1 million who could experience heart attacks and death, noted Artiom Petrov, Ph.D., co-author of "Resolution of Apoptosis in Atherosclerotic Plaque by Dietary Modification and Statin Therapy." Atherosclerosis is the slow, progressive buildup of deposits called plaques on the inner walls of arteries, which carry oxygen-rich blood to the heart, brain and other parts of the body. Over time, plaques-deposits of fat, cholesterol and calcium-can narrow coronary arteries, allowing less blood to flow to the heart muscle. Rupture of these plaques may result in acute (sudden) events, such as heart attack and death.
More than two-thirds of acute coronary events result from rupture of coronary plaques, said Petrov, a researcher in the division of cardiology at the University of California at Irvine. These plaques are likely to have large lipid (fat) collections, which are often associated with hemorrhages and harbor significant inflammation, said Petrov, explaining that inflamed cells often undergo apoptosis or suicidal death. An international team of scientists used the radiolabeled protein annexin A5 for the noninvasive imaging of atherosclerotic plaques in experimental rabbit models, binding it to the cell membrane surfaces of dying cells. By using a nuclear medicine procedure and exploring the role of diet modification and use of statins, which are cholesterol-lowering drugs, scientists found that "the radiotracer uptake demonstrated a significant correlation with inflammatory cell prevalence and the magnitude of cell death in plaques," said Petrov.
The study's findings "allow us to propose that stabilization of these plaques is a possibility," he said. This supports "the paradigm of prevention rather than therapy of a coronary event," said Petrov. The study "demonstrates that a decrease in apoptosis was associated with behavioral and therapeutic interventions-diet modification and use of statins-known to improve outcomes in coronary artery disease," he said. "Given that apoptosis contributes to plaque vulnerability, manipulation of apoptosis in atherosclerotic plaques may be of value in treating patients," said Petrov. "Our studies offer a proof of concept for usually employed strategies for the primary and secondary prevention of coronary events," he added. Additional work needs to be done in developing techniques to combine morphologic and functional imaging about plaques for them to become clinically applicable, said Petrov. He noted that this experimental study is a step toward demonstrating the virtues of molecular imaging.
The investigation was performed in the research laboratories of Jagat Narula, M.D., Ph.D., professor of medicine and chief of the division of cardiology at the University of California, Irvine. Besides Petrov and Narula, authors of "Resolution of Apoptosis in Atherosclerotic Plaque by Dietary Modification and Statin Therapy" include Dagmar Hartung, M.D., School of Medicine Hannover, Hannover, Gera number of, and division of cardiology, University of California at Irvine; Masayoshi Sarai, M.D., Navneet Narula, M.D., and Johan Verjans, M.D., all with the division of cardiology at the University of California at Irvine; Frank Kolodgie, Ph.D., and Renu Virmani, M.D., both Cardiovascular Pathology, Gaithersburg, Md.; and Chris Reutelingsperger, Ph.D., and Leo Hofstra, M.D., Ph.D., with the University Hospital Maastricht, Maastricht, the Netherlands.
