Nearly half of women using depot medroxyprogesterone acetate (DMPA), commonly known as the birth control shot, will experience high bone mineral density (BMD) loss in the hip or lower spine within two years of beginning the contraceptive, according to researchers at the University of Texas Medical Branch at Galveston. http://www.physorg.com/news180639080.html Medicine & Health Mon, 21 Dec 2009 18:40:02 EST news180639080 A year ago, Michael Bemben, professor of health and exercise science in the University of Oklahoma College of Arts and Sciences, was invited to the National Press Club in Washington, D.C., to formally announce the partnership between the American College of Sports Medicine and Sato Sports Plaza of Japan. The partnership is an effort to facilitate independent research projects around the country to examine the efficacy of a new type of training technique. http://www.physorg.com/news180021584.html Medicine & Health Mon, 14 Dec 2009 14:00:12 EST news180021584 The best way to prevent a fracture is to stop bones from reaching the point where they are prone to breaking, but understanding the process of how bones form and mature has been challenging. Now researchers at the University of Houston department of health and human performance have created a process that grows real human bone in tissue culture, which can be used to investigate how bones form and grow. http://www.physorg.com/news179594602.html Medicine & Health Wed, 09 Dec 2009 15:50:05 EST news179594602 Mammals have evolved a complex system for controlling bone remodeling. Babies require calcium for healthy bones and they obtain it from their mother's milk. Nursing mothers release calcium from their bones. Surprisingly, however, the same system also plays a key part in the control of fever and of female body temperature. This finding is reported in a paper in this week's issue of Nature from Josef Penninger's group at the IMBA in Vienna, Austria. http://www.physorg.com/news178377435.html Medicine & Health Wed, 25 Nov 2009 13:18:13 EST news178377435 Research carried out among thousands of people has shown a clear connection between depression and a loss of bone mass, leading to osteoporosis and fractures. http://www.physorg.com/news177000565.html Medicine & Health Mon, 09 Nov 2009 14:51:41 EST news177000565 (PhysOrg.com) -- Researchers have identified a mechanism that may keep a well known signaling molecule from eroding bone and inflaming joints, according to an early study published online today in the Journal of Clinical Investigation. http://www.physorg.com/news172775765.html Medicine & Health Mon, 21 Sep 2009 18:30:17 EST news172775765 A research project looking for ways to reduce bone loss in astronauts may yield methods of improving the bone health of cancer patients undergoing radiation treatment. http://www.physorg.com/news172237370.html Medicine & Health Tue, 15 Sep 2009 13:00:07 EST news172237370 (AP) -- A new study links hormone therapy for prostate cancer with a higher risk of death in older men who've had serious heart problems. http://www.physorg.com/news170440583.html Medicine & Health Tue, 25 Aug 2009 18:00:03 EST news170440583 Got high cholesterol? You might want to consider a bone density test. A new UCLA study sheds light on the link between high cholesterol and osteoporosis and identifies a new way that the body's immune cells play a role in bone loss. http://www.physorg.com/news170341957.html Medicine & Health Mon, 24 Aug 2009 14:13:17 EST news170341957 The potential role of periodontitis, an inflammatory disease of the gums, in the risk of cardiovascular disease, particularly ischemic stroke, has received growing attention during the last decade. A new study is the first prospective cohort study to use clinical measures of periodontitis to evaluate the association between this disease and the risk of cerebrovascular disease. The study is published in Annals of Neurology, the official journal of the American Neurological Association. http://www.physorg.com/news165598024.html Medicine & Health Tue, 30 Jun 2009 16:27:29 EST news165598024 A Belgian, a Canadian and a Russian blast off for the International Space Station on Wednesday as Russia steps up its rocket launches to support a doubling of the station's crew. http://www.physorg.com/news162540712.html Space & Earth Tue, 26 May 2009 07:12:21 EST news162540712 (PhysOrg.com) -- Osteoporosis and periodontitis are common diseases whose sufferers must cope with weakness, injury and reduced function as they lose bone more quickly than it is formed. While the mechanism of bone destruction in these diseases is understood, scientists have had less information about how bone formation is impaired. http://www.physorg.com/news161949438.html Medicine & Health Tue, 19 May 2009 10:58:28 EST news161949438 Osteoporosis, or bone loss, is a disease that is most common in the elderly population, affecting women more often than men. Until now, it was not clear exactly how the disease develops. Researchers of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have now elucidated a molecular mechanism which regulates the equilibrium between bone formation and bone resorption. Dr. Jeske J. Smink, Dr. Valérie Bégay, and Professor Achim Leutz were able to show that two different forms of a gene switch - a short isoform and a long isoform - determine this process. The MDC researchers hope these findings will lead to new therapies for this bone disease. http://www.physorg.com/news161528731.html Medicine & Health Thu, 14 May 2009 14:05:49 EST news161528731 (PhysOrg.com) -- Bone loss in long-duration spaceflight has been identified for decades as a significant problem affecting astronauts. More recently, scientists have found that the absence of gravity is causing astronauts on the International Space Station to lose up to 10 times more bone mass in key regions of the body each month than most post-menopausal women do in the same period of time back here on Earth. http://www.physorg.com/news156781949.html Space & Earth Fri, 20 Mar 2009 15:33:03 EST news156781949 Diets that are high in protein and cereal grains produce an excess of acid in the body which may increase calcium excretion and weaken bones, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). The study found that increasing the alkali content of the diet, with a pill or through a diet rich in fruits and vegetables has the opposite effect and strengthens skeletal health. http://www.physorg.com/news147533286.html Medicine & Health Wed, 03 Dec 2008 13:28:06 EST news147533286 Osteoporosis is a growing concern among breast cancer survivors and their doctors, because certain cancer drugs can cause bone loss. http://www.physorg.com/news146335065.html Medicine & Health Wed, 19 Nov 2008 16:37:45 EST news146335065 Montreal, November 13, 2008 - A new cross-Canada study has found that breast and prostate cancer treatment can foster bone loss. In the online edition of the Journal of Clinical Oncology, the scientists explain how loss of bone mass might affect 46,000 people diagnosed with breast and prostate cancer each year* and place them at increased risk for osteoporosis and fractures. http://www.physorg.com/news145799650.html Medicine & Health Thu, 13 Nov 2008 11:54:10 EST news145799650 Some health assessments that are routinely carried out on Earth are not practical when the "patients" are free-floating astronauts on long space flights, such as missions to Mars or the Moon. A new, NASA-funded study from the University of Houston department of health and human performance will examine how well sweat patches the size of adhesive strips can detect levels of chemicals that may indicate bone loss. http://www.physorg.com/news142085719.html Space & Earth Wed, 01 Oct 2008 13:15:19 EST news142085719 Young adults who follow a diet that is low in calories but nutritionally sound for six months appear to lose weight and fat without significant bone loss, according to a report in the September 22 issue of Archives of Internal Medicine. http://www.physorg.com/news141318507.html Medicine & Health Mon, 22 Sep 2008 16:08:26 EST news141318507 Researchers have discovered key details of how rheumatoid arthritis (RA) destroys bone, according to a study published in the Aug. 22 edition of the Journal of Biological Chemistry. The findings are already guiding attempts to design new drugs to reverse RA-related bone loss and may also address more common forms of osteoporosis with a few adjustments. http://www.physorg.com/news138450835.html Medicine & Health Wed, 20 Aug 2008 11:33:55 EST news138450835
