fMRI of human auditory cortex response to sinusoidal tones of 200, 1000, and 3000 Hz was evaluated using block design and conventional and "silent" event-related designs. Conventional event-related fMRI revealed the timecourse of the BOLD response (approximately 5 sec to peak, approximately 4 sec full-width-half-max, and approximately 14 sec recovery to baseline). Both event-related, but not bl...

BACKGROUND Human factors account for the majority of adverse events in both aviation and medicine. Human factors awareness training entitled "Crew Resource Management (CRM)" is associated with improved aviation safety. We determined whether implementation of CRM impacts outcome in critically ill patients. METHODS We performed a prospective 3-year cohort study in a 32-bed ICU, admitting 2500-3...

We determined whether the human N1 evoked by tones with different frequencies might be affected by a brief discrimination-training at one specific frequency. During 1 h training, subjects learned to discriminate a 1062 Hz tone from another tone. Before and after training, subjects heard for 26 min tones with a frequency of 1000 Hz, replaced every sixth one by test tones with frequencies randoml...

BACKGROUND Reduction of child undernutrition is one of the Sustainable Development Goals for 2030. Achievement of this goal may be made more difficult in some settings by climate change through adverse impact on agricultural productivity. However, there is only limited quantitative evidence on the link between household crop harvests and child nutrition. We examined this link in a largely subsi...

OBJECTIVE To investigate the effects of alcoholic extract of Allium sativum and Piper longum on the muscular activity of a parasitic amphistome, Gigantocotyle explanatum. MATERIALS AND METHODS Amphistomes were isometrically mounted to record the spontaneous muscular activity by using Chart 4 software program (Power Lab, AD Instruments, Australia) and to examine the effects of cumulative doses...
