Panoramic dental x-rays can be used to help identify postmenopausal women with low skeletal bone mineral density (BMD), meaning that screening for spinal osteoporosis could begin in the dentists office a new study shows.
The study included 316 postmenopausal women who had no symptoms of osteoporosis. The women were divided into two groups: 159 had no history of hysterectomy, oophorectomy or estrogen use, the remaining 157 had one or more of these histories. All had panoramic dental x-rays, and the cortical shape and width of the jaw were estimated on the x-rays. "Women with eroded cortical shape need to be referred for further BMD testing," said Akira Taguchi, DDS, PhD, department of oral and maxillofacial radiology at Hiroshima University Hospital in Japan.
Currently, questionnaires are widely used as the first step in determining which women need to have further BMD testing. This study found that dental x-rays were just as sensitive as questionnaires in identifying those women. Dental x-rays, looking at cortical shape, were 87% sensitive in identifying women with spinal osteoporosis in the group with no history of hysterectomy, oophorectomy or estrogen use and 80% sensitive for the other group. The questionnaire was found to have an 87% sensitivity rate for the women with no history and 72% for those with the history of hysterectomy, oophorectomy or estrogen use, Dr. Taguchi said.

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...
