OBJECTIVE To observe the effect of electromagnetic pulse (EMP) exposure on cerebral micro vascular permeability in rats. METHODS The whole-body of male Sprague-Dawley rats were exposed or sham exposed to 200 pulses or 400 pulses (1 Hz) of EMP at 200 kV/m. At 0.5, 1, 3, 6, and 12 h after EMP exposure, the permeability of cerebral micro vascular was detected by transmission electron microscopy ...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
Study of cerebral vascular structure broadens our understanding of underlying variations, such as pathologies that can lead to cerebrovascular disorders. The development of high resolution 3D imaging modalities has provided us with the raw material to study the blood vessels in small animals such as mice. However, the high complexity and 3D nature of the cerebral vasculature make comparison and...
OBJECTIVE We wanted to introduce a new technique for superselective catheterization of arteries with preshaping of a micro-guide wire into a shepherd's hook form, and this is useful for superselection of small arteries branching at an acute angle from a large parent artery for the treatment of tumors and hemorrhages. MATERIALS AND METHODS We developed a superselective catheterization techniqu...
The evaluation of angiogenesis inhibitors requires the analysis precise structure and function tumor vessels. anti-angiogenic agents lenvatinib sorafenib are multi-target tyrosine kinase that have been approved for treatment hepatocellular carcinoma (HCC). However, different effects on vasculature between not well understood. In this study, we analyzed both drugs vascular function, including no...
