Another week and another bunch of research headlines from Understanding Animal Research:

How do you mend a broken heart?

A team of scientists have developed a patch which could help the heart to heal after damage. Heart attacks often cause irreversible damage to the heart muscle, leaving survivors more prone to further attacks or heart failure.

In a recent study, scientists took immature heart cells from newborn rats, and placed them onto a biodegradable ‘scaffold’. They then exposed the patch to chemicals which encouraged the cells to grow, before transplanting it into the abdomens of rats.

Monkeys with two mums may eradicate mitochondrial disorders

Scientists have produced four infant monkeys using a technique which could stop women with genetic diseases passing them on to their children. Faulty DNA contained within cell structures called mitochondria was replaced by healthy mitcochondrial DNA (mDNA) from a donor egg, so genetic faults were not passed from mother to baby.

Low-carb diets could be more damaging than you’d think

A team studying the effect of diet on the cardiovascular system in mice have shown that a diet low in carbohydrates could lead to artery damage.

Three groups of mice each received a different diet: a standard mouse type, a western diet (high in fat) and a low-carb, high-protein version. After 12 weeks, one sixth more of the mice eating the low-carb diet had developed atherosclerosis compared with the standard diet.
