This is a significant research that it will help thousands of people escape form cardiac tissue. Rat hearts, stripped of their cells by detergents, have been used as a scaffold to engineer a bioartificial heart, which can amazingly pump a little like the original organ. One day, it will be used to repair heart damage or even generate new hearts for transplantation.

Blood vessels grown from patient's own tissues used successfully in human patients

Thirteen months and so far so good. Unlike earlier techniques used in Japan, which involved growing cells on a scaffold that slowly dissolved after implantation, scientists in Argentina grew whole stretches of blood vessel from the patients' own cells. The patients in question have damaged veins and arteries in their arms from regular dialysis.

This does not involve stem cells of any kind. A strip of skin is removed from the patient, but the fibroblast and endothelial cells are taken from the inside of the veins in that strip of skin

Grape juice good for the heart: study

Grape juice seems to have the same protective effect against heart disease as red wine, French scientists said on Wednesday.

Grape juice can have a similar effect (against heart disease) as red wine but without the alcohol. That is a very important message," said Dr Valerie Schini-Kerth, lead author of the study published in the journal Cardiovascular Research. Red wine and certain types of grape juice have high levels of polyphenols, which block the production of a protein linked to cardiovascular disease -- the number one killer in many Western countries

High-dose iron supplements do not impair zinc absorption in pregnant women, UK researchers report in the American Journal of Clinical Nutrition.

Iron supplements do not have an adverse effect on zinc nutrition provided the diet is adequate in zinc, Provided women are consuming a diet that contains sufficient zinc (in terms of both quantity and bioavailability), they can adapt to the increased physiological requirement for zinc and will not need zinc supplements
