Vegetarian diets and bone status.
Osteoporosis is a common chronic condition associated with progressive loss of bone mineral density (BMD) and compromised bone strength, with increasing risk of fracture over time. Vegetarian diets have been shown to contain lower amounts of calcium, vitamin D, vitamin B-12, protein, and n-3 (ω-3) fatty acids, all of which have important roles in maintaining bone health. Although zinc intakes a...
متن کاملBreaking new ground to build bone.
O steoporosis affects 10 million Americans over the age of 50 (1). Bone loss is caused by an imbalance between osteoblastmediated bone formation and osteoclastmediated bone resorption. Fifty percent of women and 20% of men over 50 will have a fragility fracture in their lifetime, contributing to 1.5 million osteoporotic fractures each year (1, 2). Prevention and treatment for osteoporosis aim t...
متن کاملNFATc1 self-promotes to build bone
Self-promotion is the way to get ahead during bone development, according to Asagiri and colleagues. They show on page 1261 that the inducible transcription factor NFATc1 must turn on its own expression for bone-resorbing osteoclasts to form. NFATc1 drives osteoclast-specific gene expression and is essential for the development of these cells in vitro. But whether NFATc1 is required in vivo was...
متن کاملSoft bone - hard arteries: a link?
Chronic kidney disease is characterized by mineral and various bone disorders associated with extraosseous and cardiovascular calcifications. Experimental studies and clinical observations in the general population and in chronic kidney disease patients show an inverse relationship between the extent of cardiovascular calcifications and bone mineral density or bone metabolic activity. Arterial ...
متن کاملInfluence of Phytase on Tibia Bone Characteristics of Broiler Quail Fed on Corn-Soybean Meal Diets
BACKGROUND: Exogenous phytase enhances the utilization of plant phytate phosphorus in poultry. OBJECTIVES: In the present study the effects of exogenous phytase was investigated on tibia bone characteristics of white quail. METHODS: In a 2x2 factorial arrangement, eighty, 11-day old unsexed chicks were randomly divided into 4 treatments of 20 replicates. All birds received one of four experimen...
