Men being treated for prostate cancer using hormone therapy maybe under-recognized for their risk of developing osteoporosis, according to a new study. Researchers writing in the January 15, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society, say few patients get tested for osteoporosis during treatment. Moreover, even men with other risk factors for osteoporosis, such as smoking or receiving the hormone treatment for a long time, are still unlikely to receive prevention or treatment.
Osteoporosis is a disease characterized by brittle, easily fractured bones that is associated with significant morbidity, mortality, and healthcare cost. It is caused by dysregulation of the hormone-regulated bone remodeling system that leads to a loss of bone mineral density. Risk factors for male osteoporosis include age-associated hormone changes, alcoholism, smoking, some medications, including those used in the treatment of prostate cancer.
Osteoporosis can be prevented and even treated using a wide range of therapies. Common prevention measures include calcium and vitamin D supplements, regular exercise. Screening test such as the dual-energy X-ray absorptiometry (DXA) scan is also available. But, even now, there is no established national consensus guiding doctors of when and what to prescribe. Treatment strategies include bisphosphonates, which have been shown to prevent further bone loss, but it is inconvenient, sometimes expensive, and may cause serious side effects. To find out how clinicians were managing osteoporosis risk in the U.S. in year 2003 and identify factors that might predict who gets treated, Tawee Tanvetyanon, M.D. from Loyola University Chicago Stritch School of Medicine reviewed the sampled records of 184 prostate cancer patients who received androgen deprivation therapy (ADT), which is known to raise the risk of osteoporosis.

Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
Just in time for Christmas, a Mars-analogue mission in Morocco, coordinated by the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI) as part of the SRC project FACILITATORS, has been successfully completed. SRC, the Strategic Research Cluster on Space Robotics Technologies, is a program of the European Union to support research and development in space technologies. From mid-November to mid-December 2018, a team of more than 30 scientists from 11 countries tested technologies for future exploration of Mars and Moon in the desert of the Maghreb state.
Close to the border with Algeria, the Erfoud region in Morocco – known to tourists for its impressive sand dunes – offered ideal conditions for the four-week...

A team of experimentalists at the U.S. Department of Energy's Ames Laboratory and theoreticians at University of Alabama Birmingham discovered a remarkably long-lived new state of matter in an iron pnictide superconductor, which reveals a laser-induced formation of collective behaviors that compete with superconductivity.
"Superconductivity is a strange state of matter, in which the pairing of electrons makes them move faster," said Jigang Wang, Ames Laboratory physicist and...
