INTRODUCTION Chronic inflammation combined with glucocorticoid treatment and immobilization puts juvenile idiopathic arthritis (JIA) patients at risk of impaired growth and reduced bone mineral density (BMD). Conventional methods for evaluating bone age and BMD are time-consuming or come with additional costs and radiation exposure. In addition, an automated measurement of bone age and BMD is l...
Life cycle changes in bone mineralization and bone size traits of the tibia and humerus were evaluated in commercial male and female broilers using dual-energy x-ray absorptiometry (DEXA). Experiment 1 evaluated weekly changes in bone traits from 2 to 7 wk of age, whereas experiment 2 compared the bone traits of 4 strains of commercial meat-type chickens from 4 to 8 wk of age. Birds were restra...
Introduction: Osteoporosis is a systemic skeletal disease in which the internal structure and ability of bone to repair its daily damage is impaired. Menopause is a vital period that affects bone health, causing rapid loss of bone mass, which in turn increases the risk of fractures in postmenopausal women. The present study was performed to evaluate the frequency pattern of risk factors for dec...
BACKGROUND Exercise during postnatal development plays a key role in determining adult bone mass and reducing the risk of fracture and osteoporosis later in life. However, the relationship between mechanically-induced osteogenesis and age is unclear. Elevated levels of estrogen during puberty may inhibit periosteal bone formation. Thus, magnitudes of mechanically-induced osteogenesis may be var...
Introduction: Osteoporosis is a multifactorial disease and several factors are involved in development and progression of the disease. The aim of this study was to increase our understanding of the relation between age, weight, BMI, postmenopausal age and bone mineral density in post menopause women. Methods: 240 Azarbaijani women aged 50-70 years having inclusion criteria were recruited. Bone...
Little is known about osteonal bone mineral and matrix properties, although these properties are of major importance for the understanding of bone alterations related to age and bone diseases such as osteoporosis. During aging, bone undergoes modifications that compromise their structural integrity as shown clinically by the increase of fracture incidence with age. Based on Fourier transform in...
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 ...
introduction: almost all malignant tumors have the potential to eventually produce bone metastasis. the aim of the current study was to report the distribution pattern and imaging characteristics of bone metastases detected by conventional whole body bone scintigraphy in patients with different types of malignancies and to assess their relationship with the complaint of bone pain. methods: as ...
