Most analyses of trabecular microarchitecture in mammals have focused on the functional significance of interspecific variation, but they have not effectively considered the influence of body size or phylogeny on bone architecture. The goals of this study were to determine the relationship between trabecular bone and body size in the humeral and femoral heads of extant primates, and to assess t...

BACKGROUND The invention of the locking plate technology leads to alterations of treatment strategies at metaphyseal fracture sites with the concept of spontaneous remodeling of trabecular bone voids. Whereas trabecular regeneration has been proven in experimental animal studies, no histologic data exist on human fracture healing with special emphasis on bone voids. METHODS In order to qualif...

Trabecular bone is a crucial and unique load-bearing tissue in the skeleton found near the ends of long bones and in the vertebral bodies. Trabecular bone has the ability to rapidly adapt to the mechanical loading environment by optimizing its mass and structure in order to bear high loads with as little bone tissue as possible, allowing bones to remain strong while minimizing their weight. Mea...

The increase of patients with osteoporosis is a social problem. Osteoporosis decreases bone strength and increases the risk of fracture. The finding of prevention and treatment methods is an urgent issue. Since cancellous bone is metabolically more active than cortical bone, cancellous bone is used for diagnosis of osteoporosis. There are a lot of studies about stress analysis of cancellous bon...

BACKGROUND Osteoporosis in long bones involves loss of cortical thickness and of the trabecular microarchitecture. Deterioration and weakening of trabecular bone tissue during osteoporosis imposes greater physiological loads on the cortical shell. However, it is unclear whether trabecular bone significantly contributes to the strength of whole bones under non-physiological impact loads. METHO...

Introduction: This study aims to evaluate the dentomaxillofacial radiographic changes in end stage renal disease (ESRD) patients who were on hemodialysis. Methods: Parathyroid hormone (PTH), calcium, phosphorus and alkaline phosphatase (ALP) measurements, as well as Panoramic and periapical radiographs were obtained from seventy four patients with a history of end stage renal disease (ESRD). Re...

Astragalus extract mixture HT042 is a standardized multiherbal mixture comprising Astragalus membranaceus, Eleutherococcus senticosus, and Phlomis umbrosa, which has proven to promote children's height growth. The aim of this study was to investigate the effects of HT042 on longitudinal bone growth, bone mass, and bone microstructure in growing rats using a high-resolution microcomputed tomogra...

UNLABELLED The roles of microarchitecture and types of trabeculae in determining elastic modulus of trabecular bone have been studied in microCT images of 29 trabecular bone samples by comparing their Young's moduli calculated by finite element analysis (FEA) with different trabecular type-specific reconstructions. The results suggest that trabecular plates play an essential role in determining...

PURPOSE To evaluate the effect of trabecular thickness and trabecular separation on modulating the trabecular architecture of the mandibular bone in ovariectomized rats. MATERIALS AND METHODS Fourteen 12-week-old adult female Wistar rats were divided into an ovariectomy group (OVX) and a sham-ovariectomy group (sham). Five months after the surgery, the mandibles from 14 rats (seven OVX and se...
