zinc is a substance that regulates neural excitability by binding whit sodium channel and potassium channel. the efficiency of free zinc ion, make down the neural survival rate, reduced the peak amplitude of na+ and make depolarization na channel, increased the peak amplitude of transition outward k+ currents and delayed rectifier. also it is an effective blocker of one subtype of tetrodoxine (...

that varies with distance, r, from the crack tip as r 1 2 . In this paper, a traction free plane stress wedge with a discrete cohesive zone along the intended crack-path is studied. Of interest is the in uence of the cohesive zone on the crack tip stress eld. Further, the in uence of the cohesive zone on the strain energy release rate is also investigated. Two example problems are studied; a do...

The anti-edema effect of edaravone, a free radical scavenger, was evaluated by magnetic resonance imaging in six patients with extensive hemispheric ischemic stroke. T(2) relaxation time in the infarct core, the boundary zone of the infarct, and the noninfarcted hemisphere were calculated, and T(2) mapping was performed before and after edaravone administration. Edaravone administration signifi...

We derive 1D steady equilibria for partially saturated downslope flow as a solution to the reposed vadose-zone problem. The equilibria are determined by two free parameters: a mean flow and a downstream saturation. Where there is no downstream saturation, a uniform outflow of constant saturation is obtained, but if an isolated zone of excess downstream saturation exists, the upstream flow speed...

The authors report on a new tungsten-hardmask-based diamond dry-etch process for fabricating diamond zone plate lenses with a high aspect ratio. The tungsten hardmask is structured by electronbeam lithography, together with Cl2/O2 and SF6/O2 reactive ion etching in a trilayer resist-chromiumtungsten stack. The underlying diamond is then etched in an O2 plasma. The authors demonstrate excellent-...
