Patients with chronic kidney disease-mineral and bone disorder (CKD-MBD) have a high risk of bone fracture because of low bone mineral density and poor bone quality. Osteoporosis also features low bone mass, disarranged microarchitecture, and skeletal fragility, and differentiating between osteoporosis and CKD-MBD in low bone mineral density is a challenge and usually achieved by bone biopsy. B...

Key words: bone mineral density; hypercalciuria; panied by decreased osteoblastic surfaces, while others, have reported reduced bone formation, increased bone osteoporosis; renal stone disease; urolithiasis resorption and a severe mineralization defect [4]. In a recent retrospective analysis of bone mineral density by dual X-ray absorptiometry, we compared a

Osteoporosis in laying hens has been a production and welfare concern for several decades. The objective of this study was to determine whether differing opportunities for exercise during pullet rearing influences long-term bone quality characteristics in end-of-lay hens. A secondary objective was to assess whether differing opportunities for exercise in adult housing systems alters bone qualit...

BACKGROUND Several lines of evidence suggest a tight association between oxidative stress and the pathogenesis of osteoporosis in humans. The intake of antioxidants may influence Bone Mineral Density by acting as free radical scavengers, preventing oxidation-induced damage to bone cells. OBJECTIVE The aim of this study was to assess the association between the Dietary Antioxidant Quality Scor...

Our study was designed to examine the validity of dual energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) measurements as predictors of whole bone breaking strength in beagle femora. DXA was used to determine the bone mineral content, bone area, and 'areal' bone mineral density. PQCT was used to determine the cross-sectional moments of inertia, volumetric d...

Bone tissue is constantly renewed during childhood and adolescence to assure skeleton growth both in size and mineral density: up to 90 percent of peak bone mass is acquired by age 18 in girls and age 20 in boys, which makes youth the best time to "invest" in bone health. The reduction in bone mineral density leading to compromised strength and microarchitecture of bone tissue can favour the oc...

Background: Familial Mediterranean fever (FMF) has episodic or subclinical inflammation that may lead to a decrease in bone mineral density (BMD). The objective of this study was to assess BMD in Egyptian children with FMF on genetic basis.Methods: A cross sectional study included 45 FMF patients and 25 control children of both sexes in the age range between 3-16 years old. The patients were re...

Background: The menopausal transition called perimenopause, happens after the reproductive years, and isspecified with irregular menstrual cycles, perimenopause symptoms and hormonal changes. Women going throughperi menopausal period are vulnerable to bone loss.Osteoporosis is one of the most common debilitating metabolic bone diseases ,especially in the women almostaround 50 years .This study ...

Introduction: Numerous factors are considered to determine human bone quality. Particularly, volumetrically evaluated bone mineral density (DXABMD) as well as the mechanical properties of bone samples serve to assess fracture risks. However, the differentiation and degree of mineral content and/or morphology effects on bone toughness remained to a large extent unanswered due to large measuring ...

UNLABELLED We provide the first reference values for bone mineral content and bone mineral density according to age and sex in Iranian children and adolescents. The prevalence of hypovitaminosis D was high, and levels of physical activity were low in our sample. Multiple regression analyses showed age, BMI, and Tanner stage to be the main indicators of bone mineral apparent density. PURPOSE N...
