The herbal medicine extracted from seeds of the Milk Thistle, Silybum marianum (silymarin) is known to have antioxidant properties and research published this week in Phytotherapy Research shows that this extract can help people significantly lower the amount of sugar bound to haemoglobin in blood, as well as reducing fasting blood sugar levels.
Silymarin contains a number of active constituents called flavolignans which are also used to help protect the liver from poisoning.
“We don’t know the exact mechanism of action for this effect, but this work shows that silymarin could play an important role in treating type II diabetes,” says lead author Fallah Huseini, who works at the Institute of Medicinal Plants, which is based in Tehran, Iran.
The data came from a randomized double-blind clinical trial involving 51 people who had had type II diabetes for at least 2 years. One group of 25 patients received 200 mg of silymarin three times a day for 4 months, while the remaining 26 received a placebo treatment. All of the patients continued to use conventional oral hypoglycaemic treatment during the trial. Patients were examined at monthly intervals.Compared with the beginning of the trial, the treatment group had a significant reduction in fasting blood glucose levels (p
“The results are very encouraging, and we now need to do further large multi-centre studies,” says Huseini.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
