New evidence about the breast cancer drug anastrozole (Arimidex) shows that the incidence of a major side-effect – bone fractures – appears to stabilise after reaching a peak at two years of treatment, easing some of the concerns about the drug.
This finding is the latest to come from evidence provided by the worlds largest international study of breast cancer treatment, the ATAC trial, which compared the aromatase inhibitor anastrozole with breast cancers current gold standard hormone treatment tamoxifen, and with both treatments combined.
The trial, involving more than 9,000 post menopausal women in 21 countries, last year revealed that over a median follow-up of patients of 33 months, anastrozole enhanced disease-free survival by 19% and cut the incidence of new tumours in the opposite breast by 58% compared to tamoxifen. This represented an absolute difference of 1.8% in favour of anastrozole. An update at 47 months median follow up showed that the gap had widened to an absolute difference of 2.6% in favour of the newer drug. Overall survival comparisons from the trial should be available next year.

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...
