skeletal tuberculosis is an unusual disease involving bone and joints and it may have different manifestations. this report introduces a 25-year-old woman suffering from chronic knee pain without any response to conservative treatments for one year. x-ray was normal but ct-scan and mri indicated a small lesion in medial condyle of the femur. the patient underwent percutaneous ct-guided biopsy. ...

In general, there is a lack of scientific documentation of nutritional value of marine by-products. The bone fraction from fish has been regarded as waste. Due to the high mineral content of fish bones, this material can be well suitable as a natural calcium source. In the present study, apparent calcium absorption of different fish bone sources was tested using growing pigs. The experimental d...

In altricial birds, growth rates and nestling morphology vary between broods. For natural selection to produce evolutionary change in these variables, ther must exist heritable variation. Since nestling traits are not any longer presents in parents, traditional offspring-parent regressions cannot estimate heritabilities of these. In this study, a partial cross-fostering experiment was performed...

We investigate the relevance of site-bond percolation theory to model the resorption and ossification of natural coral implanted in bones. The first step of the process is the vascularization of the implant seen here as a percolation threshold. The resorption and ossification can thus take place by activation of unoccupied sites. We compare our results with previously obtained experimental data...

Skeletal animation with vertex blending is a popular method to model believable 3D characters. Its main advantage is its speed that allows real-time deformation even on low-level hardware. However it has some drawbacks as well: for some movements it produces non-natural postures like twisting elbows. We present a new method called bones blending that can be used as an alternative to vertex blen...

osteoid osteoma is a benign bone tumor that rarely involves joints. although there are several reports of arthroscopic osteoid osteoma excisions, to our knowledge, there are no reports of this type of treatment for osteoid osteoma in carpal bones. we report two cases of arthroscopic (a person who had a pain in the left wrist and the other one with carpal tunnel syndrome) with excision of osteoi...

League dreams of breeding players with titanium knees, they will have to make do with bones and ligaments for the foreseeable future. Constraints come in many forms, from those that limit the range of variation available for natural selection to act upon (elephants with titanium legs seem unlikely to appear) to the physical forces of fluid dynamics, gravity and the like. In 1995, Kurt Schwenk u...

Successful fracture repair requires restoration of bone morphology and mechanical integrity. Recent evidence shows that fractured bones of neonatal mice undergo spontaneous realignment, dubbed "natural reduction." Here, we show that natural reduction is regulated by the proprioceptive system and improves with age. Comparison among mice of different ages revealed, surprisingly, that 3-month-old ...
