Since the cancellous bone displays a fluid-solid coupled porous structure, its solid matrix exhibits excellent osteogenic property and has been extensively used as the scaffold material of tissue-engineering bone. It is the aim of the present paper to examine the transversely isotropic behavior of cancellous bone. Correspondingly, a two-dimension image analysis method was developed to determine...

BACKGROUND & AIMS Children with cerebral palsy (CP) have a high prevalence of pathologic fractures. Bone quantitative ultrasonography (QUS) has emerged as a radiation-free method for the assessment of bone quality and fracture risk. In this study, we applied QUS technique in order to investigate bone status in handicapped institutionalized children and adolescents. METHODS This cross-sectiona...

An experiment was carried out to determine the effect of age and caponization on the development blood and bone characteristics development in male country chickens in Taiwan. A total of two hundred 8-wk-old LRI native chicken cockerels, Taishi meat No.13 from LRI-COA, were used as experimental animals. Cockerels were surgically caponized at 8 wks of age. Twelve birds in each group were bled an...

introduction: the low regeneration of bone in defective bones causes therapeutic problems. various strategies to assess the healing of bone defects have been used which they include histological and histo-chemical analysis in an invasive study. the purpose of this study was to determine the ultrasonic parameters of bone as a promising noninvasive technology for assessing bone repair process. ma...

background: several systemic factors and hormones are thought to regulate the fracture healing process. vitamin d has emerged as a compound or hormone that actively participates in the regulation of calcium homeostasis and bone metabolism. objectives: the aim of this study is to determine the serum changes in the level of vitamin d during the acute healing period of tibial and femoral shaft fra...

introduction: the purpose of the present study was to evaluate the effect of prednisolone on the sensitivity of bone scanning to detect the simulated closed fracture in the rat tibia.  methods: a total number of forty eight adult, male nmri rats randomly assigned into two parts, one part for 4 and other for 8 weeks experiments. each part has been divided into four groups, one group not receivi...

background: old laying hens are more prone to dietary calcium (ca) and phosphorus (p) deficiencies as  they absorb ca and p less efficiently than younger hens. objectives: in a 2×2 factorial design, the influence of diets with two levels of available phosphorus (ap) and phytase enzyme on the laying performance, egg quality and tibia bone characteristics of laying hens at their late 2nd producti...

abstract   background: the tibial diaphyseal fractures are the most common type of long bone fractures encountered by most orthopedic surgeons. in accordance with descriptive indices of tibia fractures on the basis of their location in the bone, distal tibia fractures have the second incidence of all tibia fractures after the middle tibia fractures. the purpose of the study was to assess the co...
