Objective(s): Alcohol consumption induces oxidative stress on bone, which in turn increases the risk of osteoporosis. This study determined the effects of vitamin E on bone strength and bone mineral content in alcohol-induced osteoporotic rats. Materials and Methods: Three months old Sprague Dawley male rats were randomly divided into 5 groups: (I) control group; (II) alcohol (3 g/kg) + normal ...

Only limited aspects of the transfer of calcium across the placenta to the fetus are known. Clinical outcome studies suggest that bone mineral mass in newborn infants is related to maternal size and dairy intake. Available data indicate that vitamin D deficiency may also limit in utero fetal bone mineral accumulation. Recent data suggest that maternal vitamin D status affects long-term childhoo...

Although osteoporosis reduces overall bone mass causing bone fragility, recent studies report that the remaining bone tissue is significantly stiffer. Preliminary studies indicate that alterations in bone tissue mineral content might explain these changes, albeit that other studies report conflicting observations. The objective of this study is to quantify whether the distribution of bone tissu...

The project summarized here investigated some of the parameters and relationships used to predict the performance of limestone contactors. The purpose of the project was to study the effect of limestone composition, especially the dolomite [CaMg(CO 3) 2 ] and impurity content of the stone, on the kinetics of carbonate mineral dissolution and to determine the effect of temperature on the rate of...

OBJECTIVE To estimate how axial rotation of lumbar vertebrae quantitatively affects bone mineral density, as measured by dual energy X-ray absorptiometry in the anteroposterior plane. DESIGN Observational study. SETTING University teaching hospital, Hong Kong. PATIENTS Cadaver lumbar vertebrae (L2 to L4) were removed from four adults. MAIN OUTCOME MEASURES Using dual energy X-ray absorp...

OBJECTIVE To compare bone mineral density in patients with juvenile-onset Systemic lupus erythematosus and healthy controls. PARTICIPANTS Serial bone mineral density measurements in 27 patients with juvenile-onset systemic lupus were compared to 97 healthy age-matched controls. RESULTS All patients with juvenile-onset had low bone mineral density scores at initial assessment that progressed...

OBJECTIVE This study was designed to prospectively examine differential effects of sustained "high" and "low" serum prolactin levels on bone mineral density and peripheral markers of bone metabolism. METHOD A dual-energy X-ray absorptiometer was used to measure bone mineral density. Peripheral markers of bone formation and resorption were used to measure bone metabolism in 14 Caucasian female...

introduction: rheumatoid arthritis (ra) is the most common autoimmune joint disease. osteoporosis is a well-known consequence of ra. objective: the aim of the present study was to determine the interrelationship between radiographic findings and bone mineral density (bmd) in patients with ra. methods: 70 patients with established ra (according to 1987 acr criteria) were included in a cross-sect...

background: osteoporosis is a systemic skeletal disorder characterized by low bone mineral density (bmd) that leads to an increase in bone fragility, causing an individual to be at an increased risk for fractures. asian-indians are at an increased risk for developing osteoporosis. considering the number of asian-indians in the us is rapidly growing, they likely could be an underappreciated popu...
