Modified Fixed Loop-in-Loop Technique in Mitral Valve Repair for Children.

For adults, the standard procedure for mitral valve repair of Carpentier classification type II mitral regurgitation is reconstruction with artificial chordae. In children, placement of artificial chordae of precise length between the papillary muscle and prolapsed mitral leaflet in the restricted mitral subvalvular space is technically difficult. We successfully performed mitral valve repair in 3 pediatric patients using a modified fixed loop-in-loop technique.

Pulse Shape Discrimination of n/γ in Liquid Scintillator at PMT Nonlinear Region Using Artificial Neural Network Technique.

Reactor-emitted electron antineutrinos can be detected via the inverse beta decay reaction, which produces a characteristic signal: a two-fold coincidence between a prompt positron event and a delayed neutron capture event within a specific time frame. While liquid scintillators are widely used for detecting neutrinos reacting with matter, detection is difficult because of the low interaction of neutrinos. In particular, it is important to distinguish between neutron (n) and gamma (γ) signals.

Association between obstructive sleep apnea and albuminuria in Korean adults: a nationwide populationbased study.

Background: Obstructive sleep apnea (OSA) is a sleep disorder associated with an increased risk of cardiovascular and metabolic complications. Albuminuria, an early marker of kidney damage, is a proposed risk factor for OSA and its adverse outcomes. The study explored the association between OSA and albuminuria in Korean adults.
