Porous three-dimensional hydroxyapatite scaffolds were synthesised from aragonitic cuttlefish bones via a microwave based technique. Due to its close similarity to the mineral phase found in the natural human bone matrix, synthetically produced hydroxyapatite is considered a viable apatite substitute for natural bone in a number of biomedical applications. The X-ray diffract ion data confirms t...

The mass and function of bones depends on the maintenance of a complicated balance between osteoclast-mediated bone resorption and osteoblast-mediated bone formation. Osteoporosis typically reflects an imbalance in skeletal turnover, such that bone resorption exceeds bone formation. Osteoclasts are target cells for anti-osteoporosis therapies. To discover new types of antiresorptive agents, we ...

Prior work identified a novel association between bone robustness and porosity, which may be part of a broader interaction whereby the skeletal system compensates for the natural variation in robustness (bone width relative to length) by modulating tissue-level mechanical properties to increase stiffness of slender bones and to reduce mass of robust bones. To further understand this association...

Burnt osteological materials are one focus of interest in forensic, archaeological, and palaeontological studies. We document the effects of experimental, controlled heating on a sample of modem bones and teeth from sheep and goats. Four aspects of heating specimens to between 20 and 940°C were considered: color, microscopic morphology, crystalline structure and.shrinkage. Our results show that...

The ‘Wormian bones’ or ‘sutural bones’ are small bones found at the sutures of the skull. They are unnamed bones because they vary from person to person in number and shape. They are commonly found in relation to the frontal and occipital bones. It is important to know about these bones because they can mislead in the diagnosis of fracture of skull bones. We saw a series of sutural bones in the...

SUMMARY This study is designed to confirm the changes of various bones in the osteopetrotic op/op mouse. The female adult mouse were sonicated in papain solution. After the complete treatment, the bones (Skull, Mandible, Scapula, Humerus, Radius, Ulna, Hip, Femure, Tibia, Atlas, Axis and 5th Lumbar vertebra) were measured three dimensionally using of high quality scale and low power binocular ...

Sibling competition has been shown to affect overall growth rates in birds. However, growth consists on the coordinated development of a multitude of structures, and there is ample scope for developmental plasticity and trade-offs among these structures. We would expect that the growth of structures that are used in sibling competition, such as the gape of altricial nestlings, should be priorit...

Lipoma is a very common tumor developed in soft tissue like subepithelium, however, intraosseous lipoma developed inside the bone is a quite rare tumor showing less prevalence than 0.1% or 2.5% among primary tumors developed inside the bones. Intraosseous lipoma has been reported to occur usually in metaphyseal or epiphyseal regions of long bones such as femur, tibia, fibula, and calcaneus, but...
