Osteoporosis Protection without Hormone Therapy
Just a few years ago, hormone therapy was thought to be the best way to protect bone health during and after menopause. After menopause, your body no longer makes as much new bone as it did before -- setting the stage for osteoporosis.
Because research has revealed health risks associated with long-term hormone therapy, other medications have begun to emerge as better options for treating and preventing postmenopausal bone loss and fractures.
The August issue of Mayo Clinic Women’s HealthSource reviews medication options:
Bisphosphonates: This class of medications includes alendronate (Fosamax) and risedronate (Actonel). Both can preserve bone mass and moderately increase bone density in your spine and hips. A recent study showed that alendronate increased bone mineral density in the spine continuously over a 10-year period.
Raloxifene (Evista): This medication belongs to a class of drugs called selective estrogen receptor modulators. It mimics estrogen’s beneficial effects on bone density without some of the risks associated with estrogen. Studies have shown that after three years of use, raloxifene reduced the risk of spine injuries by 36 percent.
Calcitonin (Miacalcin): This drug works by slowing the breakdown of bone and helps keep bone density stable. It’s used as a nasal spray or by injection.
Teriparatide (Forteo): This is the first of a new category of medications called anabolic agents. Unlike other drugs that are used to prevent bone loss, teriparatide stimulates bone formation. Taken by daily injection, its long-term effectiveness and safety are still being studied.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
