The laboratory and clinical evaluation of a potassium nitrate-saturated disk for the rapid detection of nitrate reductase production in anaerobes was investigated. The optimal disk concentration and incubation time were determined by utilizing triplicate sets of quadrant plates prepared with supplemented brucella (Difco) blood agar and swabbed with a 24-h broth (BBL; 135 C thioglycolate) suspen...

Nicorandil is an antianginal agent with nitrate-like and ATP-sensitive potassium channel activator properties. After activation of potassium channels, potassium ions are expelled out of the cells, which lead to membrane hyperpolarization, closure of voltage-gated calcium channels, and finally vasodilation. We present a uremic case suffering from repeated junctional bradycardia, especially befor...

We present a detailed study of the structural behavior and polarization reversal mechanism in phase III of KNO3, an unusual ferroelectric material in which the nitrate groups rotate during polarization reversal. This material was one of several studied in a previous work O. Diéguez and D. Vanderbilt, Phys. Rev. Lett. 96, 056401 2006 where methods were described for computing curves of energy ve...

tions of K+, and triple-barrelled microelectrodes measuring K pH and membrane potential m have provided Initial attempts to measure K+ activity (a K ) in vacuoles a major advance towards this goal ( Walker et al., 1995, of barley leaf epidermal cells using triple-barrelled K+1996). The incorporation of a pH-sensing barrel allows selective microelectrodes gave values that were only unequivocal a...

to determine the effects of priming and planting density on improvement of morphological and physiological traits of the two hybrid corns sc (s.c. 704) under double cropping in sari, a split plot experiment as randomized complete block design with four replications was conducted in 2010. treatments included two densities of 80 and 100 thousand plants per hectare as the first factor and osmoprim...
