background: expansion of bone marrow cavity and decreased cortical and trabecular bone tissues and osteoporosis are resulted from beta-thalassemia. the aim of this study was to assess bone mineral density (bmd) in patients with β thalassemia major and intermedia, and to determine their biochemical and hormonal profiles that may affect bmd. materials and methods: in a cross sectional study from ...

aim :  the goal of the present study was to assess the effect of omeprazole on bone mineral density and frequency of osteopenia and osteoporosis. background : the effect of omeprazole on bone turnover and the role of stomach ph alteration in calcium absorption have not been completely understood. patients and methods : in a case-control study, 58 patients who were referred to loghman hospital, ...

Bio-silica represents the main mineral component of the sponge skeletal elements (siliceous spicules), while bio-polyphosphate (bio-polyP), a multifunctional polymer existing in microorganisms and animals acts, among others, as reinforcement for pores in cell membranes. These natural inorganic bio-polymers, which can be readily prepared, either by recombinant enzymes (bio-silica and bio-polyP) ...

fracture. Several chronic medical conditions, medications, and life style factors affect bone mineral accrual. This study aims to evaluate the bone mineral densities and hip axis lengths in the local population. Materials and Methods: 336 normal Bangladeshi women age ranges 20 to 70 years had evaluation of their bone mineral densities (BMDs) by means of dual X-ray absorptiometry (DXA). Results:...

Organic–inorganic interfaces exist in many natural or synthetic materials, such as mineral–protein interfaces found in bone and epoxy–silica interfaces found in concrete construction. Here, we report a model to predict the intrinsic strength between organic and inorganic materials, based on a molecular dynamics simulation approach combined with the metadynamics method, used to reconstruct the f...

introduction: osteoporosis is a bone disease in which there is a reduction in the amount of bone mineral content leading to an increase in the risk of bone fractures. the affected individuals not only have to go through lots of pain and suffering but this disease also results in high economic costs to the society due to a large number of fractures.  a timely and accurate diagnosis of this disea...

Background: During lactation, metabolic changes in the bone in different areas of the body may affect the amount of bone mineral density.The aim of this study was to determine the relationship between breastfeeding and bone mineral density in women. Materials and Methods:  In this study, articles were searched at Cochran, Medline (via PubMed), Scopus, and Web of Science databases until June 201...

patients and methods in this cross-sectional study, we evaluated all patients referred to a single rheumatology clinic for bone mineral density measurements from 2009 to 2010. all patients who had bone mineral density measurements taken from the hip, lumbar spine, forearm, and whole body were enrolled in the study. standard bone mineral density measurements were performed using a dual energy x-...

Fossils not only provide the geologic record of evolution, they also remind us of the crucial role that mineralized tissues play in the biology of organisms. Mineralized tissues are composite structures consisting of an inorganic mineral phase, an organic phase, and cells. In this article, I provide an overview of the mineral–matrix relationships in bones and teeth, highlight the significant di...
