The solution of the Stefan problem for determination temperature fields in biological tissue during cryoablation defined areas with a view to their identification and localization, followed by therapeutic action is proposed. Three types cryoinstruments considers that as first approximation presents one-dimensional problem. Identify three isothermal surfaces reveal zone influence, freezing necro...

IN I804 Baronio clearly demonstrated that experimental free skin autografts in a sheep would survive. The wide variety of free autografts now used in plastic surgery are ample testimony to his findings. Skin grafts exchanged between identical twins were first shown to survive by Bauer in I927. Tissue transplants between members of highly inbred mouse strains are similarly accepted. A kidney tha...

Biological tissue scatters light mainly in the forward direction where the scattering phase function has a narrow peak. This peak makes it difficult to solve the radiative transport equation. However, it is just for forward-peaked scattering that the Fokker-Planck equation provides a good approximation, and it is easier to solve than the transport equation. Furthermore, the modification of the ...

active in a given area will derive nothing new from the articles in his field and a person unfamiliar with the field will end up with a few new facts but a great deal of frustration. The brief space does not allow the authors to develop their ideas to any satisfying extent and as a result there are no real "perspectives" to be found in the individual contributions, while the overall collection ...

Bioceramic scaffolds such as silicate bioceramics have been widely used for bone tissue engineering. However, their high degradation rate, low mechanical strength and surface instability are main challenges compromising their bioactivity and cytocompatibility which further negatively affect the cell growth and attachment. In this study, we have investigated the effects of silk fibroin coating o...

ameloblastomas are regarded as a homogeneous group of neoplasms with locally invasive character. they generally do not show induction of dental hard tissue formation except in few cases. biological behavior and histogenesis of these tumors is still unexplored as there is lack of relevant studies and long follow-up of these patients. so, we aimed to report this rare case of dentinoameloblastoma ...

in this article we review the application and procedures involved in scanning electron microscope (sem) to observe biological and live tissues through using sem at high resolution. we discuss practical methods for optimizing tissue preservation to achieve the two principal goals of biological specimen preparation: (a) preserving biological structures as close to their living configuration as po...
