conclusion the minimum concentration of triolein emulsion required to increase vascular permeability adequately with minimal brain edema in a cat model was 0.5%. results the lesion hemispheres showed mild hyperintensity due to edema on t2-weighted images, and contrast enhancement on post-contrast t1-weighted images in cats of group 1-5. cers showed statistically significant differences between ...
background: angiotensin ii (ang ii) has an important role on cerebral microcirculation however, its direct roles in terms of ischemic brain edema need to be clarified. this study evaluated the role of central ang ii by using candesartan, as an at1 receptor blocker, in the brain edema formation and blood-brain barrier (bbb) disruption caused by ischemia/reperfusion (i/r) injuries in rat. methods...
nimodipine (nm), as a lipophilic calcium channel blocker indicated for the prevention and treatment of neurological disorders, suffers from an extensive first pass metabolism, resulting in low oral bioavailability. polymeric micelles, self-assembled from amphiphilic polymers, have a core-shell structure which makes them unique nano-carriers with excellent performance as drug delivery. this inve...
the formation and regulation of vertebrate endogenous intestinal microbiota has been widely studied as the microbiota plays a crucial role in the host nutrition, development, and health. despite the importance of microbiota for host health, it is still unclear whether the endogenous intestinal microorganisms are genetically distinct or whether they are genetically related with each other in dif...

We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...
