Introduction:  Pressure  sores  refer  to  lesions  that  are  produced  while  a  constant  pressure  causes  necrotic  tissue to grow. The need for a better comprehension of the process has led researchers to artificial generation  of  pressure  sores.  Modeling  the  mechanical  behavior  of tissue  will  provide  a better understanding  of this  process as well as a more suitable selection ...

regeneration and engineering of functional new tissues containing the neural network have great importance. progression of neural network into the dental tissue has a crucial role in dental tissue regeneration. in the present study polymer-ceramic blended scaffolds containing different weight percentages of carbon nanotube in poly caprolactone nanofiber matrix were fabricated. morphological, me...

needle insertion is a minimally invasive technique in diagnosing and treating tumors. however, to perform a surgery accurately, the tissue should have minimum amount of displacement during needle insertion so that it reaches the target tissue. therefore, the tissue membrane has to move less to decrease rupturing under the membrane. in this study, the effect of different design parameters on dis...

Objective(s): Bioactive silicate ceramics have favorable features for applying as off-the-shelf bone and artificial tissue. Calcium silicate can enhance the generation of an immediate bond with host bone without an intervening rough surface in the bone layer. However, the silicate bioceramics have some drawback regarding their mechanical properties and chemical stabilities. Materials and Method...

Suki B, Bates JH. Lung tissue mechanics as an emergent phenomenon. J Appl Physiol 110: 1111–1118, 2011. First published January 6, 2011; doi:10.1152/japplphysiol.01244.2010.—The mechanical properties of lung parenchymal tissue are both elastic and dissipative, as well as being highly nonlinear. These properties cannot be fully understood, however, in terms of the individual constituents of the ...

nowadays, titanium-based alloys are among the most attractive metallic materials for biomedical applications (as implants) due to their non-biodegradability, low density, good mechanical properties as well as their good biocompatibility. hydroxyapatite (ca10 (po4)6(oh)2, ha) has been widely used for biomedical applications due to its bioactive, biocompatible and osteoconductive properties. firs...
