New link between calcium and cardiolipin in heart defects

To function properly, the heart needs energy from cells' powerhouses, the mitochondria. In turn, mitochondria boost their energy output when calcium levels rise around them, a signal that more energy is needed. A new study shows that a shortage of cardiolipin, a type of fat, in the mitochondrial membrane, prevents calcium from entering mitochondria. The result helps explain heart and muscle weakness in the rare genetic disorder Barth syndrome.

Coronary calcium scoring: Personalized preventive care for those most at risk

An imaging test called coronary calcium scoring can help doctors to make the right recommendation about the use of statin therapy. The test is a 10-minute CT (computed tomography) scan looking for calcium deposits in the arteries supplying blood to the heart. Calcium deposits indicate the presence of coronary plaque, also known as atherosclerosis.

'Biologically relevant' levels of a fertility hormone are detected in human hair samples

The prospect of a non-invasive test of ovarian reserve is a little closer following results from a study showing that measurement of a fertility hormone can be accurately taken from a sample of human hair.

Glowing dye may aid in eliminating cancer

When a solid cancer is surgically removed, any small piece that is left behind increases the chance of a local recurrence or spread. In a pilot study of dogs with mammary tumors, a disease very similar to human breast cancer, a team found that an injectable dye, which glows under near-infrared light, illuminated cancerous growth in the primary tumor as well as in lymph nodes.
