The actions of L-glutamate on the postsynaptic membrane of the squid giant synapse were investigated using two methods of application: ionophoresis and bath perfusion. Bath perfusion of 10 mmoll-1 sodium glutamate did not produce an appreciable depolarization of the postsynaptic membrane but reversibly blocked the neurally evoked postsynaptic potential (PSP). The postsynaptic membrane depolariz...

This study investigated specific patterns of a reactive approach to form-focused instruction: namely, corrective feedback and its relationship to error types and immediate learner repair. The database is drawn from transcripts of audio recordings made in four French immersion classrooms at the elementary level, totaling 18.3 hours and including 921 error sequences. The 921 learner errors were c...

MicroRNAs (miRNAs) are small RNAs responsible for the post-transcriptional regulation of a variety of human genes. To date, their involvement in the regulation of CBR1 is unknown. This study reports for the first time the identification of microRNA-574-5p (hsa-miR-574-5p) and microRNA-921 (hsa-miR-921) as two miRNAs capable of interacting with the 3'-untranslated region (3'-UTR) of the CBR1 gen...

Nitrous oxide (N2O) is a potent greenhouse gas. In North China, vegetable fields are amended with high levels of N fertilizer and irrigation water, which causes massive N2O flux. The aim of this study was to determine the contribution of microbial processes to N2O production and characterize isotopic signature effects on N2O source partitioning. We conducted a microcosm study that combined natu...

Abstract Background Acute cholecystitis is a common surgical condition. Gold standard treatment index cholecystectomy, although there are reasons this might not be offered. The aim of study was to explore treatments and outcomes in patients with acute cholecystitis. Method A multicentre retrospective carried out identify historic three-month cohort. Patients were identified through clinical cod...

The metabolic potential of the lung has been generally unrecognized. As this organ receives half the cardiac output, small changes in its metabolism could have profound effects on whole body fuel homeostatis. The lung has previously been considered to be unresponsive to insulin (Moxley & Longmore, 1975, Life Sciences. 17, 921). We have reexamined the effects of insulin using an improved in situ...
