PURPOSE The study aimed to investigate a relationship between the mineral content of human trabecular bone and parameters determined from compression fatigue tests at stepwise-increasing amplitude. METHODS Mineral content of trabecular bone was estimated comparing density and bone mineral density values. The relationship between the ash density, bone mineral density and factors obtained from ...

PURPOSE In the present study collagen sheets were prepared from the spongy part of the bovine femur and characterized from the physicochemical point of view. METHODS The physicochemical properties of the collagen sheets were studied using scanning electronic microscopy (SEM) and thermogravimetrical analysis (TGA). RESULTS The SEM studies showed that the collagen sheets are porous and exhibi...

this study was undertaken to assess the frequency of decreased bone mineral density and its risk factors as well as its impact on the quality of life during childhood among hemophiliac patients. materials and methods: thirty seven children with severe hemophilia a and b, referred to mofid children’s hospital during 2010, were selected. for all patients the joint score, body mass indexes, bone m...

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...

  Background: Ligament reconstruction is a common procedure in orthopedic surgery. Although several popular techniques are currently in use, new methods are proposed for secure fixation of the tendon graft into the bone tunnel. Purposes: We sought to introduce our new technique of Bashti bone plug for fixation of soft tissue graft in anterior cruciate ligament (ACL) reconstruction and to compar...

Introduction: Naturally based treatments for osteoporosis are currently limited. The purpose of this investigation was to ascertain whether bovine colostrum supplementation can improve bone health in humans. Methods: In total 63 individuals volunteered a 4-month project. They were stratified into three groups: 1) healthy post-menopausal women (n = 24); 2) with osteopenia 25); 3) people 14). Par...

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...
