Effects of School-Based Meditation Courses on Self-Reflection, Academic Attention, and Subjective Well-Being in South Korean Middle School Students.

Purpose: The purpose of this study was to examine the effects of school-based meditation courses on middle school students' self-reflection, academic attention (ability to focus in classrooms), and subjective well-being.

Design And Methods: The research design was a nonequivalent group comparison (n = 163) with pretest and post-test. The experimental group (n = 81) was given an eight-week meditation course and the control group (n = 82) was given other elective courses such as calligraphy and reading.

Superoxide and Nitric Oxide Involvement in Enhancing of N-methyl-D-aspartate Receptor-Mediated Central Sensitization in the Chronic Post-ischemia Pain Model.

Background: Recent studies indicate that reactive oxygen species (ROS) are involved in persistent pain, including neuropathic and inflammatory pain. Since the data suggest that ROS are involved in central sensitization, the present study examines the levels of activated N-methyl-D-aspartate (NMDA) receptors in the dorsal horn after an exogenous supply of three antioxidants in rats with chronic post-ischemia pain (CPIP). This serves as an animal model of complex regional pain syndrome type-I induced by hindpaw ischemia/reperfusion injury.

Reactive oxygen species and N-methyl-D-aspartate receptor-mediated central sensitization in hindlimb ischemia/reperfusion injury-induced neuropathic pain rats.

Background: Reactive oxygen species (ROS) contribute to development of neuropathic pain. A neuropathic pain syndrome was produced in rats following prolonged hindpaw ischemia/reperfusion injury, creating an animal model of complex regional pain syndrome-Type I (CRPS-I). This study was designed to evaluate the validity of this model for ROS and pain research.
