Researchers at the Institute for Aging Research (IFAR) at Hebrew SeniorLife, an affiliate of Harvard Medical School (HMS), have published a study that shows no evidence of a link between calcium intake and coronary artery calcification, reassuring adults who take calcium supplements for bone health that the supplements do not appear to result in the development of calcification of blood vessels. http://medicalxpress.com/news/2012-11-link-calcium-intake-coronary-artery.html Health Wed, 07 Nov 2012 15:20:58 EST news271524051 (HealthDay)—For men with osteoporosis, a once-yearly infusion with zoledronic acid is associated with fewer vertebral fractures and improved bone health compared with placebo, according to a study published in the Nov. 1 issue of the New England Journal of Medicine. http://medicalxpress.com/news/2012-11-once-yearly-zoledronic-acid-benefits-men.html Diseases, Conditions, Syndromes Fri, 02 Nov 2012 13:30:02 EST news271078039 (HealthDay)—Under the latest guidelines from the Institute of Medicine, it's possible that almost 80 million Americans who've previously been considered as having low levels of vitamin D don't need supplements of this nutrient at all, according to a new study. http://medicalxpress.com/news/2012-10-millions-vitamin-d-unnecessarily-analysis.html Health Wed, 24 Oct 2012 17:20:02 EST news270317386 Daily sessions of whole-body vibration may combat prediabetes in adolescents, dramatically reducing inflammation, average blood glucose levels and symptoms such as frequent urination, researchers report. http://medicalxpress.com/news/2012-10-daily-vibration-combat-prediabetes-youth.html Diabetes Fri, 19 Oct 2012 13:47:02 EST news269873213 (Medical Xpress)—For women of mixed racial or ethnic backgrounds, a new method for measuring bone health may improve the odds of correctly diagnosing their risk of osteoporosis and bone fractures, according to a UCLA-led study. http://medicalxpress.com/news/2012-10-equation-women-osteoporosis-fractures.html Diseases, Conditions, Syndromes Fri, 19 Oct 2012 08:30:30 EST news269854217 A team of Northwestern University scientists will meet with Environmental Protection Agency (EPA) administrators in Washington D.C.

A collaborative study of the mineral content, strength and flexibility of bones has found clues to the cause of bone disorders such as osteoporosis, osteogenesis imperfecta, and high bone density syndromes. The study, which brings together specialist skills in mouse gene deletion and bone measurement to assess the strength of bones in 100 mutant mouse lines, is the largest reported screen of its type for genes that regulate bone health. http://medicalxpress.com/news/2012-08-gene-deletions-mice-genes-bone.html Genetics Thu, 02 Aug 2012 17:46:24 EST news263148377 On July 19, the Canadian Institutes of Health Research announced it will be funding the work of three research teams investigating bone health.

But little work has investigated how muscle tissue affects the inner and outer layers of bone microstructure. A Mayo Clinic study looked at skeletal muscle mass and bone health across the life span and discovered distinct differences in how muscle affects the two layers of bone in men and women. The findings are published in the Journal of Bone & Mineral Research. http://medicalxpress.com/news/2012-06-links-healthy-muscle-mass-bones.html Health Wed, 20 Jun 2012 13:00:34 EST news259416027 Antimicrobial peptides (AMPs) are molecules produced in the skin to fend off infection-causing microbes. Vitamin D has been credited with a role in their production and in the body's overall immune response, but scientists at the University of California, San Diego School of Medicine say a hormone previously associated only with maintaining calcium homeostasis and bone health is also critical, boosting AMP expression when dietary vitamin D levels are inadequate. http://medicalxpress.com/news/2012-05-hormone-role-skin-infections.html Medical research Wed, 23 May 2012 14:00:16 EST news256995631 The typical naked mole rat lives 25 to 30 years, during which it shows little decline in activity, bone health, reproductive capacity and cognitive ability.
