Single sodium channel events were recorded from cell-attached patches on single canine cardiac Purkinje cells at 10-13 degrees C. Data from four patches containing two to four channels and one patch with one channel were selected for quantitative analysis. The channels showed prominent reopening behavior at voltages near threshold, and the number of reopenings declined steeply with depolarizati...

Schools are recognized as one of the most important settings for promoting social and emotional well-being among children and adolescents. This clustered randomized controlled trial evaluated Zippy's Friends, an international school-based emotional well-being programme, with 766 children from designated disadvantaged schools. The purpose of this study was to evaluate the immediate and long term...

Due to the growing emphasis of modern language pedagogy on meaningfulcommunication, L2 willingness to communicate (WTC) has recently become animportant concept in second language learning and communication. The presentstudy investigated the effects of individual differences on Iranian EFLlearners' willingness to communicate. As many as 431 students who were learningEnglish as a foreign language...

Because of photoacclimation, frequency distributions of phytoplankton single-cell fluorescence reflect variation in light histories among individual cells. As a result, phytoplankton can be used as biological tracers for vertical mixing. A time series of Prochlorococcus single-cell fluorescence distributions in the Sargasso Sea revealed changes that were qualitatively consistent with changes in...

Microspectrophotometric measurements were performedon 217 photoreceptors from cynom*us, Macacafascicularis, and rhesus, M. mulatto, monkeys. The distributions of cell types, for rods and blue, green, and red cones were : 52, 12, 47, and 44, respectively, for the cynomolgus, and 22, 4, 13, and 13 for the rhesus. Visual cells were obtairled fresh (unfixed), mounted in various media (some containi...
