Coronary calcium in heart arteries provides important clues about risk, even among younger and elderly patients and those without traditional risk factors, according to new studies.

If your doctor says you have a negative stress test, or that your cholesterol or blood pressure are normal, how assured can you be that you're not likely to have a heart attack in the next seven to 10 years?

German neurobiologists have found that certain receptors for the neurotransmitter glutamate determine the architecture of nerve cells in the developing brain. Individual receptor variants lead to especially long and branched processes called dendrites, which the cells communicate with. The researchers also showed that the growth-promoting property of the receptors is ...

Alzheimer's disease is triggered by the inappropriate processing of amyloid precursor protein to generate excess amounts of short peptide fragments called A-beta. For many years, the neurodegeneration associated with Alzheimer's disease was thought to be caused by the buildup of A-beta in insoluble, fibrous plaques. However, increasing suspicion now falls ...

Bowel cancer is one of the most common forms of cancer in developed countries but occurs much less frequently in the developing world. A high fat diet, particularly high in saturated fat, can increase a person's risk of developing bowel cancer. In addition to the high content of saturated fat, ...

Most physicians instruct pregnant women to increase their calcium intake, but a new evidence review of potential benefits of calcium supplementation for mom and baby found none, except for the prevention of pregnancy-related hypertension.

Most physicians instruct pregnant women to increase their calcium intake, but a new evidence review of potential benefits of calcium supplementation for mom and baby found none, except for the prevention of pregnancy-related hypertension. Experts agree that during pregnancy, a mother's diet and nutritional status contribute significantly to the health ...

Calcium ions play a critical role in signaling in a wide variety of cells and tissues, including muscle, immune cells, neurons, the liver, and oocytes. They can enter the cytoplasm from the extracellular environment or from intracellular stores and control the activity of numerous enzymes, other signaling molecules, transcription factors, ...

Notable levels of calcium buildup in coronary arteries can be strong predictors of heart attacks and strokes in people with diabetes and metabolic syndrome, according to a study led by UC Irvine's Heart Disease Prevention Program. The researchers also found that individuals with diabetes or metabolic syndrome but no evidence ...
