Isolated guinea pig ventricles were perfused as follows: A—45 min with normal Krebs-Ringer solution containing tracer amounts of K42 (NKR*); B—15 min with NKR*, 15 min with KR* in which half the calcium was replaced with sodium (Ca/2-KR*), 15 min with NKR*; C—15 min with NKR*, 15 min with Ca/2-KR*, 15 min with Ca/2-KR* + 10–6 m ouabain; D—15 min with NKR*, 15 min with NKR* + 3.4 x 10–4 m pentobarbital (PB), 15 min with NKR* + PB + ouabain. K influx, net K loss, contraction height, and flow rate were determined, and K efflux was calculated. Decreasing the external calcium concentration ([Ca]e) decreased K efflux with no effect on K influx; restoring [Ca]e increased K efflux without affecting influx. Ouabain decreased K influx more than it decreased K efflux. If [Ca]e was constant, reducing the contraction height with PB did not affect K movements. These findings are consistent with the hypotheses that: 1) calcium and potassium can compete for fixed intracellular anionic binding sites and 2) calcium and ouabain produce their effects on K movements by different means.

Functionalized Gold Nanoparticles

A gold nanoparticle-based colorimetric probe was developed for the determination of deferoxamine (desferrioxamine, DFO), a strong Fe(III) ion-chelator. Au-nanoparticles were synthesized and modified with 4-mercaptophenol (4MP) and mercaptoacetic acid (MAA)...
