Brain tumor-associated cerebral edema arises because tumor capillaries lack normal blood-brain barrier function; vascular permeability factor (VPF, also known as vascular endothelial growth factor, VEGF) is a likely mediator of this phenomenon. Clinically, dexamethasone reduces brain tumor-associated vascular permeability through poorly understood mechanisms. Our goals were to determine if supp...

Various preservation solutions have been evaluated for longer hypothermic cartilage storage for tissue transplantation; however, the results are mixed. This research was carried out to determine whether phosphate-buffered saline (PBS) or organ preservation solutions would preserve both the extracellular matrix and chondrocytes of articular cartilage better than culture medium during refrigerate...

Nowadays, electromagnetic metamaterials is a rapidly growing research domain involving electromagnetism, microwave and millimetre wave technology, optics, material technology and nanotechnology. In particular, paper concerns about the utilization of split ring resonators in negative permeability meta materials, the concept and the production of an isotropic negative permeability medium, an isot...

Composite soft magnetic materials consist of magnetic particles in a non-magnetic matrix. The properties of such materials can be modelled using effective medium theory. Measurements have been made of the complex permeability of composites produced using ferrite powder and polyester resin. The success of various effective medium expressions in predicting the variation of complex permeability wi...

The endothelial surface of the isolated rabbit cornea was perfused with modified KEI medium, according to the method reported previously. This in vitro cornea maintained its thickness within the normal range even after the epithelium ivas removed. The endothelial permeability of these in vitro corneas to tritiated water, >C-labeled urea, sucrose, and inulin teas determined. The reflection coeff...

The reflection, transmission spectra and the polarization transformation of linearly polarized waves in the ferrite-semiconductor multilayer structure are considered. In the long-wavelength limit, the effective medium theory is applied to describe the studied structure as a uniaxial anisotropic homogeneous medium defined by the effective permittivity and effective permeability tensors. The inve...

An analysis has been carried out to obtain the free convective heat and mass transfer characteristics of an incompressible MHD viscoelastic fluid flow immersed in a porous medium of variable permeability bounded by an infinite porous vertical plate in slip flow regime in the presence of a transverse magnetic field with heat source and radiation effects. The permeability of the porous medium dec...
