Slo2.1 channels conduct an outwardly rectifying K(+) current when activated by high [Na(+)](i). Here, we show that gating of these channels can also be activated by fenamates such as niflumic acid (NFA), even in the absence of intracellular Na(+). In Xenopus oocytes injected with <10 ng cRNA, heterologously expressed human Slo2.1 current was negligible, but rapidly activated by extracellular ap...

Vanadium is widely distributed in the environment and exhibits various biological and physiological effects in the human body. We previously documented the neuroprotective effect of sodium orthovanadate (SOV) against in rodents i.v. injected with 2 ml/kg 50 mM SOV just after the induction of middle cerebral artery occlusion (MCAO; 0 min post-MCAO). To evaluate its potential clinical use, we det...

We demonstrate efficient multimode (MM) to single-mode (SM) conversion in a 19-port photonic lantern with a 50 μm core MM delivery fiber. The photonic lantern can be used within the field of astrophotonics for coupling MM starlight to an ensemble of SM fibers in order to perform fiber-Bragg-grating-based spectral filtering. An MM delivery fiber spliced to the photonic lantern offers the advanta...

Calypso L-shaped Surface Beacon transponder has recently become available for clinical applications. We herein conduct studies to validate the Surface Beacon transponder in terms of stability, reproducibility, orientation sensitivity, cycle rate dependence, and respiratory waveform tracking accuracy. The Surface Beacon was placed on a Quasar respiratory phantom and positioned at the isocenter w...

To quantify the interaction between epinephrine infusion and carotid sinus baroreceptor reflex control of vascular capacity and resistance, we have simultaneously measured total systemic compliance, Ct, arterial compliance, Ca, changes in "unstressed vascular volume," AV0, and resistance, R, in nine dogs whose carotid sinuses were isolated and cardiac output fixed by a perfusion pump. In respon...
