Lipoprotein News and Research

RSS

A lipoprotein is a biochemical assembly that contains both proteins and lipids. The lipids or their derivatives may be covalently or non-covalently bound to the proteins.

Severely obese children have lipoprotein profiles that signal early risk of cardiovascular disease and the metabolic syndrome

"The message is urgent about the importance of prevention of cardiovascular disease in childhood. Lifestyle modification with appropriate diet and exercise can reduce cardiovascular risk in children," said lead author Daniel L. Preud'Homme, M.D., associate professor of medicine at the Wright State University School of Medicine and director of the lipid clinic at The Children's Medical Center, both in Dayton, Ohio.

Fiber supplements may lower cardiovascular risk in type 2 diabetics

Fiber supplements lower "bad" low-density lipoprotein (LDL) cholesterol and increase "good" high-density lipoprotein (HDL) cholesterol in people with type 2 diabetes, according to a study presented at the American Heart Association's Sixth Annual Conference on Arteriosclerosis, Thrombosis and Vascular Biology.

Protein that regulates cholesterol levels may lead to new drug targets in the fight against obesity

A protein that regulates cholesterol levels in the body also is responsible for maintaining a healthy balance between fat storage and fat burning, according to a UT Southwestern Medical Center study that may lead to new drug targets in the fight against obesity.

The liver may produce most of the body's good cholesterol

Research in mice suggests that the liver may produce most of the body's "good" cholesterol, an unexpected finding that might one day help scientists develop new treatments to raise levels of this heart-protecting molecule in humans.

Modest triglyceride elevations linked to coronary artery disease risk

Even modest increases in blood levels of triglycerides, as well as a type of high cholesterol known as type III hyperlipidemia, are strongly associated with coronary artery disease in people with a family history of the disease, according to a new study in the April 5, 2005, issue of the Journal of the American College of Cardiology.

Dallas heart study researchers find no link between Lp(a), calcium

The latest findings from the historic Dallas Heart Study have ruled out one of the most prominent explanations of why elevated levels of a fat-carrying protein called "lipoprotein(a)" lead to increased risks for heart attacks among whites but not among African-Americans.

Pcsk9 gene - new target for cholesterol-lowering drugs

Mice lacking a key protein involved in cholesterol regulation have low-density lipoprotein, or "bad" cholesterol, levels more than 50 percent lower than normal mice, and researchers suggest that inhibiting the same protein in humans could lead to new cholesterol-lowering drugs.

Questions about validity of HOPE TOO vitamin E study

A study published in the March 16 issue of Journal of the American Medical Association (JAMA) suggesting that a "daily-dose" of vitamin E (400 international units) among high-risk (chronically ill) cardiovascular patient populations is associated with a greater risk of heart failure is being challenged by leading health researchers around the country who claim the study lacks the adequate research and controlled sampling audience to justify this conclusion.

Dietary fat quality may be more important than fat quantity in reducing risk of cardiovascular deaths in middle-aged men

The type of dietary fats consumed by middle-aged men, especially polyunsaturated fats and linoleic acids, may be more important than total fat intake in reducing the risk of cardiovascular deaths, according to a study in the January 24 issue of Archives of Internal Medicine.

Ascorbic acid doesn't seem to help physical exercise performance

Orange juice or other sources of vitamin C (ascorbic acid), may (or may not) benefit you in terms of health and exercise, but contrary to what many people thought previously, ascorbic acid doesn't seem to help physical exercise performance.

New way to reduce fat and cholesterol levels in the body

Just in time for the holidays, McGill researchers have identified a new way to reduce fat and cholesterol levels in the body. Their program, which combines consuming plant-derived sterols (or oils) with exercise, may benefit those who are at risk of coronary heart disease.
