Fibrous dysplasia is a benign fibrous-osseous lesion in which normal bone is replaced by fibrous connective tissue and immature bone, affecting only one (monostotic) or several bones (polyostotic) and mainly occurring in children and young adults. When present in facial bones, the maxilla is more frequently involved than the mandible, which can cause facial asymmetry in addition to dental compl...

We have previously shown that high-frequency, high-resolution ultrasound can characterize the acoustic properties and composition of fatty plaques in cholesterol-fed rabbits. To determine whether quantitative ultrasound can delineate the regression of atherosclerotic lesions by detecting a change in their composition from fatty to fibrous types induced by alterations in dietary regimen, we fed ...

Three-dimensional (3D) fibrous hydrogels were fabricated by blending two photoactive polymers, poly(ethylene glycol) diacrylate (PEGDA) and poly(vinyl alcohol) (PVA), and the resulting solution was electrospun. PEGDA is a commonly used hydrogel material for tissue engineering applications since its interaction with cells can be tuned by crosslinking in a variety of bioactive molecules including...

Computation-based mathematical models of tissue indentation are capable predicting the distribution forces and mechanical properties soft tissues. This paper presents a three-dimensional model anisotropic developed using bidomain model. The hypothesizes that relative displacement between intra- extracellular spaces triggers force on mechanosensitive proteins in membrane: integrins. Some tissues...

albright syndrome is a rare condition, usually appears in the early years of life and characterized by bending or thickening of long bones. in girls, of endocrine glands disorders especially precocious puberty are the most common symptoms. also, brown pigments in the skin are another sing of this syndrome. certain mucosal and skin pigments are considerable features of the disease. etiology and ...
