This study was conducted to evaluate the performance of physical examination (PE) skills during our diagnostic medicine course and analyze the characteristics of the data collected to provide information for practical guidance to improve the quality of teaching. Seventy-two fourth-year medical students were enrolled in the study. All received an assessment of PE skills after receiving a 17-week...

HYPOTHESIS Inconsistent results have been reported using a variety of open surgical techniques to correct pectus excavatum (PE) deformities with subperiosteal resection of deformed costal cartilages. DESIGN Retrospective 6-year review of 450 consecutive patients undergoing PE repair. SETTING Tertiary care academic medical center. PATIENTS Symptomatic patients with severe PE (severity inde...

We consider perhaps the simplest non-trivial problem in advection–diffusion – a finite absorber of arbitrary cross-section in a steady two-dimensional potential flow of concentrated fluid. This problem has been studied extensively in the theory of solidification from a flowing melt, and it also arises in advection–diffusion-limited aggregation. In both cases, the fundamental object is the flux ...

To evaluate performance monitoring and error processing during lexical decision tasks, event-related potentials (ERPs) obtained by time-locked to correct and error responses were studied in 17 Parkinson's disease (PD) patients without dementia and 15 healthy elderly participants. The amplitude of error negativity (Ne) obtained by averages time-locked to error response was significantly reduced ...

The error-related negativity (ERN) and positivity (Pe) are components of event-related potential (ERP) waveforms recorded from humans and are thought to reflect performance monitoring. Error-related signals have also been found in single-neuron responses and local-field potentials recorded in supplementary eye field and anterior cingulate cortex of macaque monkeys. However, the homology of thes...

Executive functioning (EF) and motivation are associated with academic achievement and error-related ERPs. The present study explores whether early academic skills predict variability in the error-related negativity (ERN) and error positivity (Pe). Data from 113 three- to seven-year-old children in a Go/No-Go task revealed that stronger early reading and math skills predicted a larger Pe. Close...

The goal of the present study was to shed light on the respective contributions of three important action monitoring brain regions (i.e. cingulate cortex, insula, and orbitofrontal cortex) during the conscious detection of response errors. To this end, fourteen healthy adults performed a speeded Go/Nogo task comprising Nogo trials of varying levels of difficulty, designed to elicit aware and un...

In the Materials and Methods section, there is an error in the fifth and sixth sentences of the section titled “Flow cytometry.” This sentence should read: 2), PE-Cy5-conjugated anti-TCRβ (BioLegend, San Diego, CA), PE-Cy7-conjugated ant-NK1.1 (BioLegend), PE-Cy7-conjugated anti-CD8a (BioLegend), PE-CF594-conjugated anti-CD4 (BD Biosciences), and GPR30 (N15)-R Antibody (Santa Cruz Biotechnology...

Recent studies that have examined neural correlates of action monitoring with event-related potentials (ERPs) have focused on the error-related negativity (ERN) and error positivity (Pe) on error trials, as well as the correct response negativity (CRN) on correct trials. Moreover, the ERN has been assessed in relation to a number of personality traits and psychiatric disorders. However, no stud...
