The heart is a hollow, muscular organ in vertebrates, responsible for pumping blood through the blood vessels by repeated, rhythmic contractions. The term cardiac, as in cardiology, means – related to the heart – and comes from the Greek word, kardia, for heart.
Researchers implant embryonic cells into damaged hearts and prevent life-threatening heart arrhythmias.
– When researchers at Cornell, the University of Bonn and the University of Pittsburgh transplanted living embryonic heart cells into cardiac tissue of mice that had suffered heart attacks, the mice became resistant to cardiac arrhythmias, thereby avoiding one of the most dangerous and fatal consequences of heart attacks.
R. Scott Braithwaite, M.D., and his colleagues developed a new method of evaluating medical screening tests like colonoscopy, called the “payoff time,” which is the minimum amount of time it takes for the benefits from a test to exceed its harms (i.e., its complications and side effects).
– Even though current guidelines advocate colorectal cancer screenings for those with severe illnesses, they may bring little benefit and may actually pose harm, according to a recent study by Yale School of Medicine researchers published in the Archives of Internal Medicine.
American Medical Association asked the FDA to set strict limits on salt in processed foods and work to better educate the public on the benefits of a low-sodium diet.
– In an effort to reduce the burden of heart disease and stroke, the American Medical Association (AMA) testified to the Food and Drug Administration urging immediate action to reduce excess salt in food. The AMA asked the FDA to set strict limits on salt in processed foods and work to better educate the public on the benefits of a low-sodium diet.
Immune system found responsible for increased inflammation in diabetes patients. With good diabetes control, this inflammation may be reduced, possibly resulting in a reduction of cardiovascular disease as well.
– Researchers at UC Davis Health System have discovered a novel pathway that results in increased inflammation of blood vessels in patients with type 1 diabetes. Their findings suggest that, with good diabetes control, this inflammation may be reduced, possibly resulting in a reduction of cardiovascular disease as well.
Obesity and being over-weight may be bad for bone health, and childhood obesity could have a significant, long lasting negative impact on the skeleton. – Obesity may be bad for bone health, revealed by researchers at the University of Georgia. Being overweight is a known risk factor for heart disease, diabetes and a host of other health conditions. Now, obesity and over-weight may also be bad for bone health.
Anticancer drug Nexavar raised survival period in inoperable hepatocellular carcinoma patients suffering from this kind of liver cancer. – The U.S. Food and Drug Administration has approved Nexavar (sorafenib) for use in patients with a form of liver cancer known as hepatocellular carcinoma, when the cancer is inoperable. Nexavar was originally approved in 2005 for the treatment of patients with advanced renal cell carcinoma, a form of kidney cancer.
