The threshold potential for the classical depolarization-activated transient outward K+ current and Cl- current is positive to -30 mV. With the whole cell patch technique, a transient outward current was elicited in the presence of 5 mM 4-aminopyridine (4-AP) and

We compared intracellular K+ and Na+ ion concentrations during cell growth and differentiation of a mouse myeloid leukemia M1 cell line. Cells undergoing mitosis had higher K+ concentrations than quiescent cells. Treatment with a K+ channel blocker and furosemide enhanced

Previous clinical and experimental observations have demonstrated that cooling the brain can rapidly terminate focal seizures. We wished to determine whether cooling at regular intervals could prevent or attenuate the development of seizures in a model of focal epilepsy. We

Ab initio calculations on the HF-SCF 6-31g* level were performed on tautomers as well as protonated and deprotonated species of thiamin. Aspects of the proton relay function of the 4'-aminopyrimidine ring in the thiamin catalysis were studied on model systems.

The consequences of one-electron oxidation and one-electron reduction were studied for 4-aminopyrimidine (4APM), which displays prototropic tautomerism. Since experimental techniques are incapable of detecting less than 0.1% of minor tautomers, quantum-chemical calculations [DFT(B3LYP)/6-311+G(d,p)] were carried out for all possible tautomers
