The present study was conducted to determine whether provision of preformed dietary docosapentaenoic acid (DPAn-6) can replace DHA for normal long bone growth as assessed by dual-energy X-ray absorptiometry for mineral content (BMC). A newly modified artificial rearing method was employed to generate n-3 fatty acid-deficient rats. Except the dam-reared (DR; 3.1 % alpha-linolenic acid) group, ne...

Osteoporosis is a characterized by low bone mass and microarchitectural deterioration, with a consequent increase in bone fragility [1]. Bone strength impairment leads to an increased risk of fracture, as strenght reflects the integration of bone quantity (bone mineral density, BMD) and bone quality [2]. Common sites of osteoporotic fractures are spine, hip, distal forearm and proximal homerus....

A major goal of axion searches is to reach inside the parameter space region of realistic axion models. Currently, the boundaries of this region depend on somewhat arbitrary criteria, and it would be desirable to specify them in terms of precise phenomenological requirements. We consider hadronic axion models and classify the representations R_{Q} of the new heavy quarks Q. By requiring that (i...

background: the aim of the present study was to evaluate the relationship between the bone density of various regions of jaws and skeletal bones. materials and methods: a total of 110 patients with a mean age of 55.01 ± 10.77 years were selected for the purpose of the present descriptive study. dual x-ray energy absorptiometry (dxa) was carried out to determine bone mineral density (bmd) of the...

background: thalassemia/haemoglobinopathy is a hereditary disease with increased erythropoiesis and expansion of the bone marrow cavity. consequently, there is a reduction in trabecular bone tissue resulting in osteopenia/osteoporosis. the present study was performed to determine bone mineral density (bmd) in children and adolescents with major thalassemia and its correlation with serum ferriti...

Background: The Singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (AP) radiograph. The purpose of this study was to compare between Singh index and bone mineral density measurement using dual energy X-ray abs...

To determine whether bone mineral density measurement using the Calscan successfully predicts the actual bone mineral density, as measured by dual-energy X-ray absorptiometry. We included all patients≥65 years with a hip fracture screened on osteoporosis by both dual-energy X-ray absorptiometry and the Calscan during the period April 2008 to April 2011. The bone mineral density was expressed as...
